Gynecol Oncol 2021 Jun 1. Epub 2021 Jun 1.

Division of Gynaecology and Human Reproduction Physiopathology, Department of Medical and Surgical Sciences (DIMEC)., IRCCS Azienda Ospedaliero-Universitaria di Bologna. S. Orsola Hospital. University of Bologna, Via Massarenti 13, Bologna 40138, Italy.

Background: 2021 ESGO/ESTRO/ESP guidelines for the management of patients with endometrial carcinoma (EC) encourage molecular classification and propose a new prognostic risk stratification based on both pathologic and molecular features. Although deep myometrial invasion (DMI) has been considered as a crucial risk factor in EC, it is unclear if its prognostic value is independent from The Cancer Genome ATLAS (TCGA) groups.

Aim: To assess if the prognostic value of DMI is independent from the TCGA groups in EC patients.

Materials And Methods: A systematic review and meta-analysis was performed by searching through 5 electronic databases, from their inception to March 2021, for all studies that allowed to assess DMI as a prognostic factor independent of the TCGA groups in EC patients. Pooled hazard ratio (HR) of DMI for overall survival (OS) and disease-free survival (DFS) was calculated at multivariable analyses including TCGA groups as a variable. Superficial myometrial invasion (<50% of myometrial thickness) was considered as a reference. In DFS analyses, locoregional and distant recurrence were separately considered for one study.

Results: Five studies with 2469 patients were included in the systematic review and 3 studies with 1549 patients in the meta-analysis. Pooled HR of DMI was 1.082 (CI 95% 0.85-1.377; p = 0.524) for OS, 1.709 (CI 95% 1.173-2.491; p = 0.005) for DFS, 1.585 (CI 95% 1.154-2.178; p = 0.004) for DFS additionally considering locoregional recurrence for one study, and 1.701 (CI 95% 1.235-2.344, p = 0.001) for DFS additionally considering distant recurrence for the same study.

Conclusions: DMI does not appear as an independent prognostic factor for OS in EC patients; instead, it seems to affect the risk of recurrence independently from the TCGA groups. Further studies are necessary to confirm these findings and to assess the prognostic impact of DMI separately in each TCGA group.

Laparotomic versus robotic surgery in elderly patients with endometrial cancer: A systematic review and meta-analysis.

Int J Gynaecol Obstet 2021 May 27. Epub 2021 May 27.

Division of Gynecology and Human Reproduction Physiopathology, Department of Medical and Surgical Sciences (DIMEC), IRCCS Azienda Ospedaliero-Univeristaria di Bologna, University of Bologna, Bologna, Italy.

Background: Although robotics has been shown to improve outcomes in some high-difficulty surgical category patients, it is unclear if such an approach may improve outcomes in elderly patients with endometrial carcinoma (EC).

Objective: To compare robotic and laparotomic surgery in the treatment and staging of elderly EC patients.

Materials And Methods: A systematic review and meta-analysis was performed assessing the risk of overall, intra-operative, and peri-operative complications associated with the surgical approach (laparotomic vs robotic) for elderly patients with EC by relative risk (RR). Pooled means ± standard deviation of length of stay were compared with the unpaired t test. Subgroup analyses for overall complications were performed based on different age cut-offs (>70, >65, and >75 years) and severity of complications (minor and major). A value of P less than 0.05 was considered significant.

Results: Five studies with 7629 EC patients were included. Pooled RR for robotic compared with laparotomic surgery was 0.40 (P < 0.001) for overall, 0.46 (P = 0.18) for intra-operative, and 0.43 (P < 0.001) for peri-operative complications. Pooled difference between means ± standard deviation of length of stay for robotic versus laparotomic surgery was -3.34 (P < 0.001). At subgroup analyses, pooled RR of overall complications for robotic surgery versus laparotomic surgery was 0.34 (P < 0.001) in the >70 years, 0.51 (P < 0.01) in the >65 years, 0.20 (P = 0.12) in the >75 years groups. Pooled RR was 0.50 (P = 0.1) in the minor complications subgroup, and 0.42 (P = 0.002) in the major complications subgroup.

Conclusion: Robotics might be a viable alternative to the laparotomic approach for EC in elderly patients because it significantly decreases the risk of overall and peri-operative complications (mainly major complications), and the length of stay when compared with laparotomy. The decrease in risk of overall complications is greater with increasing patient age.

The unbearable burden of endometriosis: Results from a large cohort about anxiety reduction during the first outpatient evaluation.

J Psychosom Res 2021 May 18;147:110512. Epub 2021 May 18.

Gynecology and Human Reproduction Physiopathology, Dipartimento di Scienze Mediche e Chirurgiche (DIMEC), Via Massarenti, 13, IRCCS, Sant'Orsola-Malpighi Hospital, University of Bologna, Bologna, Italy.

Objective: To evaluate the impact of the first outpatient evaluation on anxiety levels in women with suspected endometriosis. Secondarily, we investigated which individual characteristics exerted the greatest influence on distress levels.

Methods: Women referred to our academic center between January 2019 and March 2020 on the suspicion of endometriosis were enrolled in this prospective, observational study. Before the visit, participants answered questionnaires such as the Generalized Anxiety Disorder-7 (GAD) and the Spielberg State Trait Anxiety Inventory (STAI) Y6. After the visit, the STAI-Y6 was resubmitted to each woman, along with the Patient Global Impression of Improvement (PGII) questionnaire. Women's and physicians' satisfaction with the visit were also evaluated using a 5-point scale.

Results: One hundred and four women were enrolled. Anxiety levels decreased after the evaluation (STAI-Y6 60.0 ± 15.0 vs 40.8 ± 14.2, P < .001). Higher reductions were noted in patients who had higher baseline anxiety levels (est. change -24.3; 95% CI -29.2, -19.5; P < .001), had previously sought information online (est. change -15.9; 95% CI -21.4, -10.5; P < .001), and when endometriosis was not confirmed, but not in those waitlisted for surgery (est. change 1.7; 95% CI -5.9, 9.2; P 0.659). Most patients' mood improved after the examination (67%) and were satisfied with the visit (98%).

Conclusions: Anxiety levels are reduced after medical examination in women with higher baseline distress and who sought information online. To create a trustful relationship with women, providing them with tailored counselling, seems essential to improve their psychological wellbeing.

Comparison of perioperative outcomes between standard laparoscopic and robot-assisted approach in patients with rectosigmoid endometriosis.

Acta Obstet Gynecol Scand 2021 May 17. Epub 2021 May 17.

Division of Gynecology and Human Reproduction Physiopathology, Department of Medical and Surgical Sciences (DIMEC), IRCCS, Sant'Orsola-Malpighi Hospital, University of Bologna, Bologna, Italy.

Introduction: Robot-assisted laparoscopic surgery (RALS) has gained widespread application in several surgical specialties. Previous studies on the feasibility and safety of RALS versus standard laparoscopy (S-LPS) for rectosigmoid endometriosis are limited and reported conflicting data. This study aims to compare S-LPS and RALS in patients with rectosigmoid endometriosis in terms of perioperative surgical and clinical data.

Material And Methods: This is a multicentric, observational, prospective cohort study including 44 patients affected by rectosigmoid endometriosis referred to two tertiary referral centers for endometriosis from September 2018 to September 2019. Patients were divided into two groups: 22 patients underwent S-LPS, and 22 underwent RALS. Our primary outcome was to compare operative time (from skin incision to suture) between the two groups. Secondary outcomes included: operative room time (patient entry into operative room and patient out), estimated blood loss, laparotomic conversion rate, length of hospital stay, perioperative complications, and evaluation of endometriosis-related symptoms at 12-month follow up.

Results: The two groups were comparable regarding preoperative and surgical data, except for higher rates of hysterectomies and bilateral uterosacral ligament removal procedures in the RALS group. Also after adjusting for these discrepancies, operative time was similar between S-LPS and RALS. Operative room time was statistically longer in the RALS group compared with that of S-LPS. No statistically significant difference was found concerning other study outcomes. Pain and bowel symptoms improved in both groups at 12-month follow up.

Conclusions: If performed by expert teams, RALS provides similar perioperative outcomes compared with S-LPS in rectosigmoid endometriosis surgical treatment, except for longer operative room time.

Endometriosis, the hidden enemy: multivariable fractional polynomial approach for evaluation of preoperative risk factors in the absence of ureteral dilation.

Fertil Steril 2021 May 4. Epub 2021 May 4.

Gynecology and Human Reproduction Physiopathology, Dipartimento di Scienze Mediche e Chirurgiche (DIMEC), Istituto di Ricovero e Cura a Carattere Scientifico (IRCCS) Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy.

Objective: To determine whether it is possible to predict the risk of ureteral endometriosis (UE) using a mathematical model based on preoperative findings.

Design: Prospective observational study conducted between January 2017 and April 2020.

Setting: Tertiary-level academic referral center.

Patient(s): Three hundred consecutive women of reproductive age with a diagnosis of posterior deep infiltrating endometriosis (DIE) scheduled for laparoscopic surgery.

Intervention(s): Before surgery, anamnestic data and the severity of endometriosis-related symptoms were evaluated, and all patients underwent a complete gynecological examination. Transvaginal and transabdominal ultrasound were performed to map the endometriotic lesion. Ureteral involvement was surgically and histologically confirmed.

Main Outcome Measure(s): To select important risk factors for UE and determine a suitable functional form for continuous predictors, we used the multivariable fractional polynomial.

Results: UE was surgically found in 145 women (48.3%). Based on our multivariable polynomial mathematical model, UE was significantly associated with adenomyosis, parametrial involvement, and previous surgery for endometriosis. A posterior DIE nodule with a transverse diameter >1.8 cm was associated with a higher probability of ureteral involvement.

Conclusions: Posterior DIE nodule with a transverse diameter >1.8 cm, adenomyosis, parametrial involvement, and previous surgery for endometriosis appear to be good predictors of UE.

Long-Term Medical Therapy after Laparoscopic Excision of Ovarian Endometriomas: Can We Reduce and Predict the Risk of Recurrence?

Gynecol Obstet Invest 2021 13;86(1-2):170-176. Epub 2021 Apr 13.

Gynecology and Human Reproduction Physiopathology, Dipartimento di Scienze Mediche e Chirurgiche (DIMEC), IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy.

Objectives: Up to 32% of women experience anatomic recurrence after conservative surgery for endometriomas, while pain recurs in 10-40% of cases. Long-term postoperative hormonal therapy is recommended to prevent disease recurrence. We evaluated the efficacy of long-term therapy with estroprogestins (EPs) or progestins (Ps) in preventing endometrioma recurrence, as identifiable cysts and subjective symptoms, after laparoscopic excision.

Design: This retrospective cohort study included 375 women submitted to laparoscopic endometrioma excision. Women were followed up at 6 and 12 months and then yearly after surgery. Based on postoperative medical therapy, women were divided into 4 groups: nonusers, cyclic EP users, continuous EP users, and progestogen users. Materials, Setting, Methods: Anamnestic and anthropometric characteristics were collected as well as clinical and surgical data. Gynecological examination, and transvaginal and transabdominal ultrasound scans were performed. Pain (numerical rating score >5) and endometrioma recurrence at ultrasound (ovarian cyst with typical sonographic features ≥10 mm in mean diameter) were recorded at each examination. The reoperation rate in women with recurrence was investigated.

Results: The median follow-up was 3.7 years with a maximum of 16.7 years. Most patients used EPs (119 cyclic and 61 continuous users), 95 used P, and 100 were nonusers. In 135 women (36%), endometriotic cyst recurrence was diagnosed, with a mean diameter of 18.7 ± 10.8 mm (range 10-55 mm). The median recurrent cyst-free time was 7.9 years (95% CI 5.8-10.8). Dysmenorrhea was the first symptom to reappear, affecting 162 patients (43.2%). Upon multivariable regression analysis, continuous users had a lower risk of relapse (OR 0.56, 95% CI 0.32-0.99), in terms of both cysts and symptom recurrence, than patients who received no medications. The reoperation rate was 16.2%.

Limitations: The main limitation of this study is its retrospective design. Also, women switching therapies throughout the follow-up period were sorted into one of the study groups based on the longest treatment taken, without considering the discontinuation rates.

Conclusions: Long-term EPs, administered in a continuous regimen and starting immediately after conservative surgery for endometriomas, seem to reduce the disease recurrence risk.

Tumor-infiltrating lymphocytes and POLE mutation in endometrial carcinoma.

Gynecol Oncol 2021 May 12;161(2):621-628. Epub 2021 Mar 12.

Division of Gynaecology and Human Reproduction Physiopathology, Department of Medical and Surgical Sciences (DIMEC). IRCCS Azienda Ospedaliero-Univeristaria di Bologna. S. Orsola Hospital. University of Bologna, Via Massarenti 13, Bologna 40138, Italy.

Background: Polymerase-ε (POLE)-mutated endometrial carcinomas (ECs) have displayed an increased number of tumor-infiltrating lymphocytes (TIL) compared to POLE-wild-type ECs. However, it is unclear if TIL may aid in identifying POLE-mutated ECs when molecular data are unavailable. The identification of a POLE mutation surrogate may be crucial to translate TCGA/ProMisE risk assessment in the clinical practice.

Aim: To assess TIL as histological surrogate of POLE mutation in EC.

Materials And Methods: Seven electronic databases were searched from their inception to September 2020 for studies that allowed data extraction about TIL and TCGA/ProMisE groups of EC. We calculated pooled sensitivity, specificity, positive and negative likelihood ratios (LR+ and LR-), diagnostic odds ratio (DOR) and area under the curve (AUC) on SROC curves of TIL in distinguishing POLE-mutated from i) POLE-wild-type, ii) no specific molecular profile (NSMP), iii) POLE-wild-type/MMR-proficient, iii) MMR-deficient ECs.

Results: 10 studies assessing 1169 women were included in the qualitative analysis. TIL-high pattern showed: sensitivity = 0.65, specificity = 0.63, LR + =2.06, LR- = 0.48, DOR = 4.39, AUC = 0.7532 for POLE-mutant vs POLE-wild-type ECs; sensitivity = 0.85, specificity = 0.73, LR + =2.80, LR- = 0.22, DOR = 15.17 for POLE-mutant vs NSMP ECs; sensitivity = 0.85, specificity = 0.66, LR + =2.49, LR- = 0.25, DOR = 10.30 for POLE-mutant vs POLE-wild-type/MMR-proficient ECs; sensitivity = 0.68, specificity = 0.44, LR + =1.38, LR- = 0.64, DOR = 2.68, AUC = 0.6694 for POLE-mutant vs MMR-deficient ECs.

Conclusion: TIL-high pattern shows a moderate accuracy in distinguishing POLE-mutated from POLE-wild-type ECs after the exclusion of MMR-deficient cases. TIL might be considered in an integrate algorithm to identify POLE-mutated ECs when sequencing is unavailable. Further studies are necessary in this regard.

Transvaginal ultrasound features of normal uterosacral ligaments.

Fertil Steril 2021 Jul 12;116(1):275-277. Epub 2021 Feb 12.

Division of Obstetrics and Gynecology, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy.

Objective: To show a step-by-step technique to assess normal uterosacral ligaments (USLs) during transvaginal ultrasound. Uterosacral ligaments represent the most common location of deep infiltrating endometriosis (DIE) in the posterior compartment and their involvement significantly increases the risk of ureteral lesions. The ultrasonographic diagnosis of DIE involving USLs is characterized by a wide range of accuracies described between studies, probably due to variations in the examination technique, quality of ultrasound equipment, and experience of the operators. Although described as a new classification system of DIE involving USLs, the technique for visualizing normal USLs has not yet been described.

Design: Stepwise demonstration of the technique with narrated video footage.

Setting: Academic tertiary hospital.

Patient(s): The video shows a 33-year-old nulliparous woman scheduled for laparoscopic removal of a para-ovarian cyst of approximately 6 cm. Procedural steps were repeated and confirmed in another four patients submitted to laparoscopy for benign diseases (Table 1). Moreover, we here show the case of a 29-year-old woman with an isolated DIE nodule of the right USL with a comparison of laparoscopic and ultrasound findings. To better point out the technique applied in a clinical setting we show also cases of infiltrated USLs (Table 2) during the ultrasound scan in women scheduled for endometriosis surgery. Informed consent was obtained from all of the patients. The study protocol was approved by the local institutional Ethics Committee (580/2018/Oss/AOUBo).

Intervention(s): To understand correctly the right position of USLs we performed an ultrasound during a surgical procedure; in this way it was possible to recognize the area of interest while the surgeon filled the pouch of Douglas with fluid and highlighted the anatomical area with pliers. Uterosacral ligaments can be seen in the mid-sagittal and transverse view of the uterus.

Main Outcome Measure(s): Description of appearance of normal USLs during transvaginal ultrasound.

Result(s): Uterosacral ligaments, at transvaginal ultrasound, appear as hyperechoic stripes starting from the cervix and pointing laterally in a semi-horizontal direction.

Conclusion(s): We provided a step-by-step technique (Table 3) that may be a useful tool to see accurately both the USLs at transvaginal ultrasound.

Uterine Fundus Remodeling after Hysteroscopic Metroplasty: A Prospective Pilot Study.

J Clin Med 2021 Jan 12;10(2). Epub 2021 Jan 12.

Gynecology and Human Reproduction Physiopathology Unit, IRCCS Azienda Ospedaliero-Universitaria di Bologna, 40138 Bologna, Italy.

The septate uterus is the most common congenital uterine malformation and is treated by hysteroscopic metroplasty. There are few studies on the fundal uterine changes that occur after surgery. We designed a pilot prospective observational study to evaluate by three-dimensional transvaginal ultrasound (3D-TVS) the changes not only of the internal fundal uterine profile, but also of the external one, after hysteroscopic metroplasty. Sixty women who underwent hysteroscopic metroplasty for partial or complete uterine septum (U2a and U2b subclasses of ESHRE/ESGE classification) were enrolled. We performed 3D-TVS after surgery confirming optimal removal of the septum. However, at ultrasound follow-up after three months, we observed a significant increase ( < 0.001) in the residual septum (Zr) (3.7 mm (95% CI: 3.1-4.4)), the myometrial wall thickness (Y) (2.5 mm (95% CI: 2.0-3.0)) and the total fundal wall thickness (Y + Zr) (6.2 mm (95% CI: 5.5-6.9)). Forty-three patients (72%) required a second step of hysteroscopic metroplasty. Moreover, the shape of uterine fundus changed in 58% of cases. We actually observed a remodeling of the uterine fundus with modifications of its external and internal profiles. Therefore, we propose to always perform a second ultrasound look at least three months after the metroplasty to identify cases that require a second- step metroplasty.

Indocyanine Green Fluorescence Angiography after Full-thickness Bowel Resection for Rectosigmoid Endometriosis-A Feasibility Study.

J Minim Invasive Gynecol 2021 Jun 11;28(6):1225-1230. Epub 2021 Jan 11.

Division of Gynaecology and Human Reproduction Physiopathology, Department of Medical and Surgical Sciences (DIMEC), IRCCS Azienda Ospedaliero-Universitaria di Bologna, S. Orsola Hospital, University of Bologna, Bologna, Italy (all authors).

Study Objective: To evaluate feasibility of near-infrared (NIR)-indocyanine green (ICG) imaging for bowel vascularization assessment after full-thickness bowel resection for rectosigmoid endometriosis (RSE).

Design: This is a prospective, single-center, preliminary study on consecutive patients who were symptomatic submitted to discoid or segmental resection for RSE and NIR-ICG evaluation for vascular assessment of the anastomotic line from May 2018 to January 2020.

Setting: Tertiary university hospital.

Patients: Thirty-two women with RSE meeting eligibility criteria were included for study analysis.

Interventions: NIR-ICG evaluation of anastomotic line vascularization after RSE removal.

Measurements And Main Results: Fluorescence degree of the anastomotic line was assessed with a 0 to 2 Likert scale, as follows: 0 or "absent" (no fluorescence observed), 1 or "irregular" (not uniform distribution or weak fluorescence), and 2 or "regular" (uniform distribution of fluorescence and similar to the proximal colon). In all the patients included in the study (100%), NIR-ICG imaging allowed the evaluation of fluorescence degree of the anastomotic line. No adverse reaction related to ICG use was recorded. The protocol did not greatly lengthen operating time (median, 4 [range, 3-5] minutes). Excellent interoperator agreement was observed. Most of the patients (31 of 32, 96.9%) showed regular fluorescence on the anastomotic line; in 1 patient with irregular fluorescence at NIR-ICG after discoid excision, the anastomotic suture was reinforced through interrupted stitches. We had 1 case of anastomotic leakage after segmental resection with intraoperative good fluorescence at NIR-ICG evaluation.

Conclusion: NIR-ICG imaging for anastomotic perfusion assessment after discoid or segmental resection for RSE seems to be a feasible, safe, and reproducible method.

Relationship between morular metaplasia and squamous differentiation in endometrial carcinoma.

Pathol Res Pract 2021 Jan 30;217:153307. Epub 2020 Nov 30.

Pathology Unit, Department of Advanced Biomedical Sciences, University of Naples "Federico II", Naples, Italy.

Morular metaplasia (MM) is a peculiar type of metaplastic change commonly observed in endometrial lesions, which is defined by the absence of overt squamous features and a characteristic immunophenotype. The nature of MM and its relationship with conventional squamous differentiation (SD) is still undefined. Here, we present a morphological and immunophenotypical study of cases with mixed MM/SD and conventional SD, providing new insights on this field. Twenty cases of endometrioid carcinoma (10 with mixed MM and SD and 10 with conventional SD) were assessed by immunohistochemistry for β-catenin, CD10, CDX2, ki67, p63, p40, estrogen receptor (ER), progesterone receptor (PR) and cytokeratins (CK) 5/6, 7, 8/18 and 19. In mixed MM/SD cases, SD was mostly located within the MM areas; several degrees of SD development were observed within MM, from cells with larger cytoplasm and prominent membrane, to overt SD with morular shape and ghost cell keratinization. In the MM→SD transition, there was progressive loss of nuclear β-catenin, CD10, CDX2 and CK8/18 expression, increase of CK5/6 and CK7 expression, and stable CK19 positivity. ER, PR and ki67/MIB1 expression was low-to-negative in both MM and SD. The squamous cell markers p63 and p40 were mostly expressed at the interfaces between MM and SD. Conventional SD cases showed direct transition from glandular epithelium to SD with a surface growth and no ghost cell keratinization; immunohistochemistry showed strong positivity for ER, PR and all CKs, basal positivity for p63, p40 and ki67/MIB1, negativity for nuclear β-catenin, CD10 and CDX2. In conclusion, MM appears as the precursor of a peculiar form of SD, which differs morphologically and immunophenotypically from conventional SD. Defining MM based on the absence of overt squamous might not be meaningful. Further studies are necessary to clarify the nature of MM.

Fertility Sparing Treatment of Endometrial Cancer with and without Initial Infiltration of Myometrium: A Single Center Experience.

Cancers (Basel) 2020 Nov 29;12(12). Epub 2020 Nov 29.

Gynecology and Human Reproduction Physiopathology Unit, IRCCS Policlinico di Sant'Orsola, DIMEC, University of Bologna, 40138 Bologna, Italy.

Endometrial cancer (EC) is the fourth largest female cancer in Europe and North America. In 5% of cases, the diagnosis is made in women who wish to become pregnant. In our retrospective study, we reported our experience about fertility sparing treatment of G1 endometrioid endometrial cancer (G1 EEC) or atypical endometrial hyperplasia/endometrial intraepithelial neoplasm (AEH/EIN) in young women desiring pregnancy treated in our Center. Conservative treatment was based on operative hysteroscopy and hormone therapy with megestrol acetate (160 mg/die for 9 months). For the first time we included women with G1 EEC with minimal myometrial infiltration. The minimum follow-up period was two years and consisted of serial outpatient hysteroscopies with endometrial biopsies. Among the 36 women with G1 EEC we observed one case of disease persistence and four recurrences and four recurrences among the 46 women diagnosed with AEH/EIN. To date, 35 live births were obtained in both groups. Our results advance the hypothesis that conservative treatment can represent a safe and feasible alternative to propose to young women with desire for pregnancy. Further randomized and multicentric studies are needed to arrive at unambiguous and standardized guidelines on the surgical and medical treatment of young women with EEC or AEH/EIN.

Adhesion barriers in laparoscopic myomectomy: Evidence from randomized clinical trials.

Int J Gynaecol Obstet 2021 Mar 8;152(3):308-320. Epub 2021 Jan 8.

Gynecology and Human Reproduction Physiopathology, Dipartimento di Scienze Mediche e Chirurgiche (DIMEC), IRCCS S. Orsola Hospital, University of Bologna, Bologna, Italy.

Objective: To evaluate the effectiveness of different adhesion barriers in the prevention of de novo adhesion development after laparoscopic myomectomy.

Methods: A systematic review was performed by searching seven electronic databases for all randomized clinical trials (RCTs) comparing the use of any absorbable adhesion barrier (i.e. intervention group) with either no treatment or placebo (i.e. control group) in the prevention of adhesion development after laparoscopic myomectomy.

Results: Eight RCTs with a total of 748 participants (392 in the intervention group and 356 in the control group) were included. The assessed adhesion barrier methods were: oxidized regenerated cellulose (ORC) in two studies, auto-crosslinked hyaluronic acid (HA) gel in two studies, 4% icodextrin solution in one study, modified HA and carboxy-methylcellulose in one study, polyethylene glycol ester trilysine amine solution plus a borate buffer solution in one study, and polyethylene glycol amine plus dextran aldehyde polymers in another study.

Conclusion: Adhesion barrier methods showing the most promising results were: ORC, auto-crosslinked HA gel, and polyethylene glycol amine plus dextran aldehyde polymers.

Prevalence of adenomyosis in endometrial cancer patients: a systematic review and meta-analysis.

Arch Gynecol Obstet 2021 01 23;303(1):47-53. Epub 2020 Oct 23.

Gynecology and Obstetrics Unit, Department of Neuroscience, Reproductive Sciences and Dentistry, School of Medicine, University of Naples Federico II, Naples, Italy.

Introduction: Several studies have assessed the histological co-existence of endometrial carcinoma (EC) and adenomyosis. However, the significance of this association is still unclear.

Objective: To assess the prevalence of adenomyosis in women with EC for a better understanding of the association between the two diseases.

Materials And Methods: A systematic review and meta-analysis was performed by searching electronics databases from their inception to March 2020, for all studies that allowed extraction of data about prevalence of adenomyosis in EC patients. Adenomyosis prevalence was calculated for each included study and as pooled estimate, with 95% confidence interval (CI).

Results: Eight retrospective cohort studies assessing 5573 EC patients were included in our analysis. Of total, 1322 were patients with adenomyosis, and 4251 were patients without adenomyosis. Pooled prevalence of adenomyosis in EC patients was 22.6% (95% CI 12.7-37.1%).

Conclusion: Adenomyosis prevalence in EC patients was not different from that reported for other gynecological conditions. The supposed association between the two diseases appears unsupported.

Laparoscopic cervicopexy for correction of apical genital prolapse in 10 steps: a pilot study.

Int Urogynecol J 2021 May 25;32(5):1313-1316. Epub 2020 Sep 25.

Gynaecology and Human Reproduction Physiopathology, DIMEC, S. Orsola Hospital, University of Bologna, Bologna, Italy.

Introduction: Surgical repair of pelvic organ prolapse is one of the most frequent gynecological procedures, and its frequency is expected to increase as the population is gradually aging. Mesh use in urogynecological surgery should be limited because of important and life-treating complications. Sacral mesh-less and lateral procedures have been described as safe and effective to treat apical compartment prolapse. In this video, we describe a new laparoscopic mesh-less cervicopexy in women with symptomatic uterovaginal prolapse who did not desire uterine preservation.

Methods: Eleven women with symptomatic uterovaginal prolapse [stage 2 or higher according to the Pelvic Organ Prolapse Quantitative (POP-Q) classification system] underwent laparoscopic mesh-less cervicopexy to the sacrum and transverse fascia between May 2018 and June 2019. We performed application of the right uterosacral ligament starting from the sacrum and two semicontinous sutures including the transverse fascia, round ligament, prevescical peritoneum, pubocervical fascia and cervix that were subsequently knotted.

Results: At 6-month follow-up, the objective success rate for apical prolapse (POP-Q score C > -1) was 90.9% (10/11 women). Only one woman presented stage 3 apical prolapse recurrence with vaginal buldge.

Conclusion: Laparoscopic mesh-less cervicopexy for uterovaginal prolapse seems to be a feasible surgical technique at 6-month follow-up.

Comparison of fertility outcomes after laparoscopic myomectomy for barbed versus nonbarbed sutures.

Fertil Steril 2021 01 12;115(1):248-255. Epub 2020 Sep 12.

Gynaecology and Human Reproduction Physiopathology, Dipartimento di Scienze Mediche e Chirurgiche (DIMEC), S. Orsola Hospital, University of Bologna, Bologna, Italy.

Objective: To assess the impact on women's reproductive outcomes of barbed sutures to repair uterine breaches during laparoscopic myomectomy compared with traditional smooth sutures.

Design: Retrospective, monocentric cohort study, with information on subsequent pregnancies prospectively acquired for some women.

Setting: Tertiary-level academic referral center.

Patient(s): Women older than 18 years who had undergone a laparoscopic myomectomy and had sought pregnancy afterward, divided into two groups based on type of suture used to repair the uterine wall: group A (nonbarbed) and group B (barbed).

Intervention(s): Laparoscopic removal of FIGO types 3, 4, 5, and 6 uterine leiomyomas by use of either only barbed sutures or only traditional smooth sutures to reconstruct the uterine defect.

Main Outcome Measure(s): Pregnancy achievement rates, delivery modes, main pregnancy complications, perioperative complications for both kinds of suture, and the trend of the use of barbed sutures over time at our center.

Result(s): Of 164 patients included, 83 were in group A and 81 in group B. Ninety-one patients (55.5%) experienced at least one postoperative pregnancy, with no differences between the groups (group A 60.5%; group B 50.6%). Of the 103 recorded postoperative pregnancies, 70 (68%) resulted in live births, 29 (28.1%) in first-trimester miscarriages, and 4 (3.9%) were ongoing.

Conclusion(s): Barbed sutures have a similar impact on reproductive outcomes as smooth conventional threads, both in terms of pregnancy and obstetric complication rates, after laparoscopic myomectomy.

Transperineal Ultrasound Visual Feedback Assisted Pelvic Floor Muscle Physiotherapy in Women With Deep Infiltrating Endometriosis and Dyspareunia: A Pilot Study.

J Sex Marital Ther 2020 24;46(7):603-611. Epub 2020 Jun 24.

Gynaecology and Human Reproduction Physiopathology Unit, DIMEC, S. Orsola Hospital, University of Bologna, Bologna, Italy.

A prospective study with the aim to evaluate the effects of pelvic floor physiotherapy was conducted among women with deep infiltrating endometriosis (DIE) and associated dyspareunia. At initial evaluation superficial and deep dyspareunia were assessed using a numerical rating scale, and levator hiatus area (LHA) was assessed with 3-D/4-D transperineal ultrasound. Women underwent five individual sessions of ultrasound visual feedback assisted pelvic floor physiotherapy. One month after the therapy, dyspareunia and LHA were reassessed and compared with pre-therapy data. Pelvic floor physiotherapy seems to improve both superficial and deep dyspareunia and pelvic floor muscle relaxation in women with DIE.

Adenomyosis and endometriosis in adolescents and young women with pelvic pain: prevalence and risk factors.

Minerva Pediatr 2020 Jun 16. Epub 2020 Jun 16.

Gynecology and Human Reproduction Pathophysiology, DIMEC, S. Orsola Hospital, University of Bologna, Bologna, Italy.

Aim: To evaluate the prevalence of ultrasound diagnosis of adenomyosis and endometriosis in young women complaining of pelvic pain and to find the symptoms and clinical characteristics associated with these diseases in young women.

Methods: Cross-sectional study, including 100 young women (14-24 years) with a history of chronic pelvic pain. Women were asked detailed medical hystory and pain symptoms scores (Visual Analogue Scale) and underwent gynecological examination and ultrasound evaluation.

Results: The prevalence of endometriosis and adenomyosis in young women amounted to 25.0% and 46.0%, respectively. A significant correlation was found between ovarian endometriosis and adenomyosis. Dysmenorrhea and dyspareunia were risk factors for adenomyosis. Dyschezia, dyspareunia, chronic pelvic pain, presence of sonographic soft markers suggestive of pelvic adhesions, being a worker and having a previous surgery were risk factors for endometriosis. Young women (20-24 years) had a higher incidence of both adenomyosis and endometriosis than adolescents (14-19 years).

Conclusions: Our outcomes strengthen the hypothesis of a progressive and common course of the natural history of endometriosis, which initially may manifest with symptoms, then with signs of pelvic adhesions and finally as adenomyosis, ovarian endometriomas or deep infiltrating endometriosis.

Feasibility and safety of laparoscopic approach in obese patients with endometriosis: a multivariable regression analysis.

Arch Gynecol Obstet 2020 09 6;302(3):665-670. Epub 2020 Jun 6.

Department of Obstetrics and Gynecology, DIMEC, S. Orsola Hospital, University of Bologna, Massarenti, 13, 40138, Bologna, Italy.

Purpose: To evaluate the feasibility and safety of laparoscopic excision of endometriotic lesions in obese women.

Methods: Retrospective analysis of prospectively collected data involving consecutive women scheduled for complete laparoscopic removal of macroscopic endometriotic lesions between January 2012 and November 2018. Operative time, laparotomic conversion rates, complication rates, and length of hospital stay were recorded.

Results: One thousand two hundred thirty women were enrolled and divided into two main groups, according to the World Health Organization classification of obesity, obese (body mass index ≥ 30 kg/m) and non-obese (body mass index < 30 kg/m). During the study period, 91 (7.4% of overall study cohort) obese women underwent surgery. At univariate analyses, significant differences between the two groups were found in terms of age, rates of severe endometriosis, American Society of Anesthesiologists physical status classification ≥ III, and different surgical procedures. Significant differences in terms of median operative time [125 (interquartile range (IQR) 85-165) in obese group vs 110 min (IQR 75-155) in non-obese group, P = 0.04] were observed. There were no significant differences between the obese and non-obese groups with respect to the other variables of interest. After adjusted multivariable regression models for potential confounders, difference in operating time (coefficient of 13.389; 95% CI 1.716, 25.060) was still found to be significant.

Conclusion: In our tertiary care referral center, laparoscopic removal of endometriosis is feasible and safe, except for a slight increase of operative time and conversion rate.

Rectosigmoid Endometriosis Vascular Patterns at Intraoperative Indocyanine Green Angiography and their Correlation with Clinicopathological Data.

Surg Innov 2020 Oct 5;27(5):474-480. Epub 2020 Jun 5.

Gynecology and Human Reproduction Physiopathology, Dipartimento di Scienze Mediche e Chirurgiche (DIMEC), 18508Sant'Orsola Hospital, University of Bologna, Italy.

The objective of the study was to evaluate the presence of different rectosigmoid endometriosis (RSE) vascular patterns using intraoperative indocyanine green (ICG) angiography and their correlation with clinicopathological data. A prospective pilot study on 30 consecutive symptomatic women affected by RSE and scheduled for minimally invasive surgery between May 2018 and January 2019. ICG was used for the intraoperative evaluation of RSE vascularization. Perfusion grade was classified as follows: 0-1 = no or low fluorescence (hypovascular pattern); 2 = regular fluorescence, similar to healthy surrounding rectosigmoid tract (isovascular pattern); and 3-4 = diffuse or abundant fluorescence (hypervascular pattern). Thirty women were intravenously injected with ICG after nodule exposure. No adverse effects related to ICG use were noted. After a 5- to 50-s latency from ICG injection, the real-time direct visualization of RSE perfusion showed diffuse or abundant fluorescence in 12/30 (40%) women, while in the remaining 18/30 (60%), fluorescence was poor or absent. No statistical differences were observed between the 2 groups regarding preoperative, intraoperative, and histological variables analyzed, except for a maximum diameter of bowel lesions and microvessel density (MVD). Hypovascular nodules had a larger maximum diameter (39.5 ± 15.6 mm vs 30.3 ± 11.4 mm, < .05) and lower MVD (154.6+/43.6 vs 281.1+/-77.4, < .05) than hypervascular ones. ICG angiography is a feasible and safe technique to intraoperatively assess RSE vascularization. The majority (60%) of endometriotic nodule presented a hypovascular pattern. The hypovascular pattern seems to be associated with a larger nodule size and lower MVD.

Laparoscopic surgery for benign adnexal conditions under spinal anaesthesia: Towards a multidisciplinary minimally invasive approach.

J Gynecol Obstet Hum Reprod 2020 Sep 16;49(7):101813. Epub 2020 May 16.

Gynaecology and Human Reproduction Physiopathology, Dipartimento di Scienze Mediche e Chirurgiche (DIMEC), S. Orsola Hospital, University of Bologna, Via Massarenti 13, 40138 Bologna, Italy.

Background: Laparoscopic gynaecological surgery is commonly performed under general anaesthesia with endotracheal intubation. In general surgery, locoregional anaesthesia was applied to laparoscopic procedures, increasing minimally invasive surgery advantages.

Aims: To assess and compare postoperative pain after laparoscopic adnexal procedures for benign conditions under spinal anaesthesia (SA) versus general anaesthesia (GA). Furthermore, anaesthesiologic, surgical and clinical data were evaluated in both groups.

Materials And Methods: This is a prospective cohort study performed in a tertiary level referral centre for minimally invasive gynaecological surgery (Gynaecology and Human Reproduction Physiopathology, University of Bologna). Women scheduled for adnexal laparoscopic surgery for benign conditions between February and May 2019 were assigned to receive either SA or GA with endotracheal intubation. A sample size of 13 women per group was needed to detect a 2-point difference in pain scores.

Main Findings: 13 women were enrolled in the SA arm, 15 in the GA arm. In the SA cohort, the most common intraoperative adverse event was shoulder pain, reported by 3/12 women. At 1, 8, 12, 24 and 48 h after surgery pain was significantly lower in the SA arm (p < .05). Patients submitted to SA experienced no need for opioid drugs administration, unlike those receiving GA. Patients' mobilization and return of bowel function were noted significantly earlier in the SA group (p < .05).

Conclusions: SA is a feasible, safe and effective anaesthesiologic technique for laparoscopic gynaecological procedures for benign conditions, allowing a better control of postoperative pain. Women undergoing SA achieve earlier mobilization and bowel canalization. During the Covid-19 pandemics, SA could be useful in reducing the need for invasive procedures on respiratory tract.

Acute abdominal pain in non-pregnant endometriotic patients: not just dysmenorrhoea. A systematic review.

J Obstet Gynaecol 2021 Jan 21;41(1):7-20. Epub 2020 Apr 21.

Gynaecology and Human Reproduction Physiopathology, Dipartimento di Scienze Mediche e Chirurgiche (DIMEC), S. Orsola Hospital, University of Bologna, Bologna, Italy.

Endometriosis, defined as the presence of functional endometrial tissue outside the uterine cavity, presents mainly with pelvic pain and infertility. Acute abdominal pain in non-pregnant patients with endometriosis might be minimised as a typical feature of the disease, while endometriosis is rarely considered in the differential diagnosis of acute abdominal pain. Our objective was to conduct a systematic review of the current literature of cases of acute abdomen/acute abdominal pain in non-pregnant endometriotic patients. We performed a PubMed/MEDLINE search of studies published from January 1990 to December 2018, selecting English language reports and series of non-pregnant patients with acute abdomen and histological confirmation of endometriosis. The studies were revised by two independent authors. Data were abstracted and compiled for analysis. Fifty articles reporting 62 patients were identified. The complications were classified according to anatomical sites in bowel, urinary tract, and genital organs emergencies. Rarely was the first diagnostic hypothesis endometriosis, misdiagnosis was frequent. The time frame from symptoms onset to management was often long. This is the first systematic review evaluating acute abdomen/acute abdominal pain in non-pregnant endometriotic patients. These conditions are rare but possibly life-threating and require prompt diagnosis and emergent medical or surgical treatment.

Use of Indocyanine Green for Intraoperative Perfusion Assessment in Women with Ureteral Endometriosis: A Preliminary Study.

J Minim Invasive Gynecol 2021 01 10;28(1):42-49. Epub 2020 Apr 10.

Unit of Gynecology and Human Reproduction Physiopathology, Department of Medical and Surgical Sciences, S. Orsola Hospital, University of Bologna, Bologna, Italy (Drs. Raimondo, Borghese, Arena, Ambrosio, Del Forno, Degli Esposti, Casadio, Mattioli, Mastronardi, and Seracchioli).

Study Objective: To evaluate the feasibility, safety, and potential usefulness of near-infrared imaging (NIR) with indocyanine green (ICG) to assess ureteral perfusion after conservative surgery (ureterolysis or nodule removal) for ureteral endometriosis. Any changes to the surgical plan regarding intraoperative ureteral stent placement after NIR-ICG evaluation and early postoperative outcomes were recorded.

Design: Prospective case series study.

Setting: Tertiary level referral center for endometriosis and minimally invasive gynecology.

Patients: Consecutive symptomatic women scheduled for laparoscopic conservative ureteral surgery for ureteral endometriosis.

Interventions: After ureterolysis or nodule removal, residual perfusion of the ureters with regular caliber and peristalsis was evaluated through NIR-ICG imaging. Ureteral perfusion grade was defined as absent, irregular, or regular. Time required for NIR-ICG assessment, interoperator agreement regarding ureteral perfusion grade, any changes to the surgical plan after NIR-ICG evaluation, perioperative complications, and clinical-radiologic outcomes at early follow-up were recorded.

Measurements And Main Results: A total of 31 ureters were examined with NIR-ICG imaging after conservative ureteral procedures. ICG assessment required 5.4 + 2.3 minutes. No complications related to fluorescence imaging were observed. Local ischemia supporting ureteral stent placement was suspected in 5 ureters (16.1%) at white light. Of these, 2 (40.0%) presented regular fluorescence; thus, ureteral stent placement was avoided. In the remaining 3 (60.0%), NIR-ICG confirmed irregular or absent fluorescence, requiring ureteral stent placement. Interoperator agreement regarding NIR-ICG evaluation was high. At a 3-month follow-up, all procedures were clinically and radiologically successful.

Conclusion: NIR-ICG imaging after conservative surgery for ureteral endometriosis seems to be a feasible, safe, and useful tool to assess ureteral perfusion and guide surgical decision, together with other visual cues at white light. However, this approach needs to be validated by further larger and controlled studies.

Real three-dimensional approach vs two-dimensional camera with and without real-time near-infrared imaging with indocyanine green for detection of endometriosis: A case-control study.

Acta Obstet Gynecol Scand 2020 10 17;99(10):1330-1338. Epub 2020 May 17.

Department of Gynecology and Human Reproduction Physiopathology, Department of Medical and Surgical Sciences, S. Orsola Hospital, University of Bologna, Bologna, Italy.

Introduction: The complete surgical removal of endometriosis lesions is not always feasible because some implants may be very small or hidden. The use of intraoperative near-infrared radiation (NIR) imaging after intravenous injection of indocyanine green (ICG) coupled with robotic technical advances, including three-dimensional (3D) and high-resolution vision, might improve detection rates.

Material And Methods: This is a retrospective, multicenter case-control study (Canadian Task Force classification II-2) on medical records of women with endometriosis who underwent surgery at the Catholic University of Rome (Controls) and the University of Bologna (Cases) between January 2016 and March 2018. Surgical and post-surgical data from the procedures were collected. We compared the visual detection rate of endometriotic lesions using near-infrared radiation imaging after intravenous injection of indocyanine green (NIR-ICG) in Real 3D (Cases) with the 2D Camera approach (Controls) in symptomatic women with pelvic endometriosis.

Results: Twenty cases were matched as closely as possible with 27 controls. The numbers of suspected lesions identified both with the white light and the NIR-ICG approach were 116 and 70 in the Controls (2D) and Cases (3D), respectively. Among them, 16 of 116 controls (13.8%) and 12 of 70 cases (17.1%) were identified using only NIR-ICG imaging and collected as occult lesions (P = .536). The overall NIR-ICG lesion identification showed a positive predictive value of 97.8%, negative predictive value of 82.3%, sensitivity of 82.0%, and specificity of 97.9% for the Control group, and a positive predictive value of 100%, negative predictive value of 97.1%, sensitivity of 97.1%, and specificity of 100% for the Case group, confirming that NIR-ICG imaging is a good diagnostic and screening test (P = .643 and P = .791, according to the Cohen κ tests, respectively for the laparoscopic and robotic groups).

Conclusions: The few differences observed did not seem to be clinically relevant, making the 2 procedures comparable in terms of the ability to visually detect endometriotic lesions. Further prospective trials are needed to confirm our results.

Unicornuate uterus with noncommunicating functional horn: diagnostic workup and laparoscopic horn amputation.

Fertil Steril 2020 04;113(4):885-887

Gynaecology and Human Reproduction Physiopathology, Department of Obstetrics and Gynecology, DIMEC, Sant'Orsola Academic Hospital, University of Bologna, Bologna, Italy.

Objective: To describe the diagnosis and the management of hematometra in a patient with unicornuate uterus with noncommunicating functional horn (hemi uterus and rudimentary uterine hemicavity).

Design: Video case report.

Setting: Minimally invasive gynaecology unit.

Patient(s): Sixteen-year-old nulliparous woman admitted to the gynaecologic emergency department with pelvic pain during menses.

Intervention(s): Two-dimensional transvaginal ultrasound, magnetic resonance imaging, and laparoscopic rudimentary horn resection.

Main Outcome Measure(s): Description of a case of anomaly of the female reproductive tract treated by laparoscopy.

Result(s): After pain reduction and stabilization of clinical condition, ultrasound and magnetic resonance were performed, which detected a hemi uterus with a right rudimentary uterine hemicavity and a hematosalpinx. The removal of the right rudimentary uterine horn was successfully performed. The patient was in good health at the 3-month follow-up visit.

Conclusion(s): Laparoscopic amputation of a functional rudimentary horn is considered the basic and traditional surgical option for women with hemiuterus. A detailed diagnostic evaluation should be performed to avoid misdiagnoses of other anomalies with blind hemicavity, which may be treated by hysteroscopy. Laparoscopic surgery with minimally invasive approach could be an essential tool to treat these cases, achieving optimal results with low postsurgical pain and a short hospital stay.

Feasibility and safety of two different surgical routes for the eradication of recto-vaginal endometriosis with vaginal mucosa infiltration (Endo-Vag-r study).

Acta Obstet Gynecol Scand 2020 08 27;99(8):1050-1056. Epub 2020 Feb 27.

Department of Obstetrics and Gynecology, Dipartimento di Scienze Mediche e Chirurgiche (DIMEC), S. Orsola Hospital, University of Bologna, Bologna, Italy.

Introduction: Recto-vaginal endometriosis surgical management needing partial colpectomy is a surgically challenging condition and has been associated with a notable risk of major postoperative complications. In the present study we sought to compare feasibility and safety of total laparoscopic (TL) and vaginal-assisted (VA) routes in women affected by symptomatic recto-vaginal endometriosis with vaginal mucosa infiltration scheduled for minimally invasive surgery.

Material And Methods: Multi-centric, retrospective cohort study on medical records of consecutive reproductive age women submitted to complete macroscopic eradication of symptomatic recto-vaginal endometriosis with vaginal mucosa infiltration between March 2013 and November 2017. The two groups were compared in terms of preoperative data and surgical outcomes.

Results: 84 women were included in the study (TL = 57 and VA = 27). The two groups were comparable in terms of preoperative, surgical and postoperative data. The major postoperative complications rate was 5.3% (3 of 57) in the TL group and 7.4% (2 of 27) in the VA group, without a significant difference. In the TL group we reported one case of bowel anastomosis dehiscence and two cases of pelvic abscess. In the VA group, one case of small bowel perforation after extensive adhesiolysis treated with ileal resection and one case of rectal sub-occlusion after segmental resection and mechanical anastomosis were noticed.

Conclusions: In women affected by recto-vaginal endometriosis with vaginal mucosal infiltration, perioperative outcomes do not seem to be influenced by the surgical route adopted.

Question Mark Sign and Transvaginal Ultrasound Uterine Tenderness for the Diagnosis of Adenomyosis: A Prospective Validation.

J Ultrasound Med 2020 Jul 7;39(7):1405-1412. Epub 2020 Feb 7.

Department of Gynecology and Human Reproduction Pathophysiology, Saint'Orsola Hospital, University of Bologna, Bologna, Italy.

Objectives: To evaluate the diagnostic accuracy of the classic ultrasound (US) signs of adenomyosis, the question mark sign and transvaginal ultrasound (TVUS) uterine tenderness, in the diagnosis of adenomyosis.

Methods: This was a prospective study including 78 patients waiting for hysterectomy for uterine benign diseases and undergoing preoperative US examinations to evaluate all criteria for US diagnosis of adenomyosis as reported by the consensus statement of the Morphological Uterus Sonographic Assessment group. A US diagnosis of adenomyosis was made in the presence of 2 or more Morphological Uterus Sonographic Assessment features. Moreover, the question mark sign and TVUS uterine tenderness were evaluated. Ultrasound features were compared with the histologic examination, which was considered the reference standard for the diagnosis of adenomyosis. The Cohen κ coefficient was used to measure the accordance between US and histologic results. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of each US feature were calculated.

Results: The prevalence of adenomyosis in the sample was 33.3%. The sensitivity, specificity, PPV, NPV, and accuracy of TVUS in the diagnosis of adenomyosis were 77%, 96%, 91%, 89%, and 90%, respectively. Myometrial heterogeneity was the most frequently encountered feature (100%) but showed low specificity (7%). The question mark sign and TVUS uterine tenderness showed sensitivity, specificity, PPV, NPV, and accuracy of 41%, 96%, 83%, 77%, and 69% and 69%, 65%, 66%, 81%, and 67%.

Conclusions: The question mark sign and TVUS uterine tenderness are useful tools for the diagnosis of adenomyosis.

Frequency and clinical impact of Dolichocolon in women submitted to surgery for rectosigmoid endometriosis.

J Gynecol Obstet Hum Reprod 2020 Apr 1;49(4):101697. Epub 2020 Feb 1.

Department of Obstetrics and Gynecology, DIMEC, S. Orsola Hospital, University of Bologna, Italy.

Introduction: Rectosigmoid endometriosis and Dolichocolon can both present with a triad of chronic abdominal pain, constipation and bloating. The relationship between these two pathologies is unknown. The present study aims to determine the frequency of DC in women with rectosigmoid endometriosis and its possible impact on pre- and post-operative symptoms.

Material And Methods: We conducted a retrospective cohort study on 113 consecutive patients submitted to magnetic resonance imaging enema and subsequent complete surgical removal for symptomatic rectosigmoid endometriosis between June 2015 to June 2018. Dolichocolon is an anatomic variant characterized by redundancies and lengthening of the colon. We divided our study population according to its presence or absence. The two groups were compared in terms of demographic data, surgical findings and pre- and post-operative clinical variables. Pain symptoms were assessed through numerical rating scale from 0 to 10. Bowel complaints included constipation, bloating and diarrhea.

Results: Thirty-five patients (31 %) presented a dolichocolon at magnetic resonance imaging enema. The two groups were comparable in terms of demographic data, pre-operative clinical variables and surgical findings. At 6-month follow-up, there was a significant improvement of symptoms, except for constipation and bloating in dolichocolon group. In particular, we observed with a statistical difference (p < .05) the persistence of constipation and bloating in dolichocolon group compared to non-dolichocolon group.

Conclusions: Dolichocolon was observed in one third patients with rectosigmoid endometriosis and could influence surgical outcomes for rectosigmoid endometriosis in terms of relief of bowel symptoms.

Transvaginal Ultrasound and Doppler Features of Intraligamental Myomas.

J Ultrasound Med 2020 Jul 16;39(7):1253-1259. Epub 2020 Jan 16.

Department of Obstetrics and Gynecology, S. Orsola Malpighi Hospital, University of Bologna, Bologna, Italy.

Objectives: To describe the ultrasound (US) features of intraligamental myomas (IMs) using Morphological Uterus Sonographic Assessment group standardized terminology.

Methods: This was a retrospective monocentric study. A total of 125 consecutive women with a preoperative US diagnosis of a myoma located close to the uterine isthmus (International Federation of Gynecology and Obstetrics stages 5, 6, and 7) from 2016 to 2019 who underwent laparoscopic or laparotomic myomectomy or hysterectomy were included for study analyses. The US data were retrieved from US reports and stored digital images by 2 authors. Ultrasound features of myomas were described according to Morphological Uterus Sonographic Assessment terminology. Clinical data for the study population were retrieved from the patients' records.

Results: Nineteen women with a surgical confirmation of an IM were included in the study group; the remaining population constituted the control group (n = 106). Non-uniform echogenicity was detected in 17 of 19 (89%) of IMs compared to 26 of 106 (25%) fibroids in the control group (P < .001). The presence of shadowing was detected in 12 of 19 (63%) IMs compared to 94 of 106 (89%) cases in the control group (P = .004). Intraligamental myomas were more vascularized tumors compared to myomas in the control group (P = .004). Transvaginal US showed high specificity for the diagnosis of an IM (0.93; 95% confidence interval, 0.87-0.96).

Conclusions: On US imaging, IMs appear as vascularized solid tumors with nonuniform echogenicity; cones of shadows were less frequent in IMs than the control group, and this finding can help in the differential diagnosis. Knowledge of their specific US features could help sonographers make an accurate diagnosis, allowing them to plan correct surgery and avoid severe complications.
