BMC Womens Health 2020 07 13;20(1):144. Epub 2020 Jul 13.

Department of Obstetrics and Gynaecology, Hanover Medical School, Carl-Neuberg-Straße 1, 30625, Hannover, Germany.

Background: Endometriosis can be associated with considerable pain and sterility. After surgical excision of moderate or severe endometriosis lesions, the rate of recurrence reaches up to 67%. The objective of this retrospective study was to establish the recurrence and pregnancy rates following surgical resection of stage III/IV endometriosis lesions. Indications for operation were endometriosis symptoms, sonographic findings and/or infertility.

Methods: A total of 456 patients who underwent stage III/IV endometriosis surgery between 2004 and 2014 were sent a questionnaire relating to their postoperative medical treatment, pregnancies, relief of symptoms and recurrence. Responses of 206 patients (45.2%) and their clinical data were analysed for this study.

Results: A total of 66.5% (N = 137) of patients had stage III disease, and 33.5% (N = 69) had stage IV disease. The average age was 37 years (17-59). A total of 63.1% (N = 130) of surgeries were performed by laparoscopy, 21.8% (N = 45) were performed by laparotomy and 15% (N = 31) were performed by conversion. Complete resection of endometriosis lesions was achieved in 90.8% of patients (N = 187). After surgery, 48.5% (N = 100) of the women did not receive hormonal treatment; the main reason was the desire for children in 53%. Complete or partial relief in complaints was achieved in 93.2% (N = 192). The rate of recurrence was 21.8% (N = 45). The statistically significant factors that was associated with a higher risk to develop recurrence was an age < 35 (p < 0.005). After surgery, 65.8% (79/120) of patients who wished to have children became pregnant. There was a statistically significant association among a higher postoperative pregnancy rate and age < 35 (p < 0.003) in multivariate logistic regression analysis and laparoscopic surgical access in univariate logistic regression analysis (p < 0.01).

Conclusion: We assessed the high percentage of complete or partial relief of symptoms of 93.2%, the high postoperative pregnancy rate of 65.8% and the low rate of recurrence of 21.8% compared to international literature to be very encouraging for women suffering from moderate and severe endometriosis. Though laparoscopy is considered the 'gold standard'of endometriosis surgery, laparotomy still may be indicated in patients with extensive endometriosis especially to preserve reproductive function.

Clinical diagnosis and therapy of uterine scar defects after caesarean section in non-pregnant women.

Arch Gynecol Obstet 2015 Jun 17;291(6):1417-23. Epub 2014 Dec 17.

Department of Obstetrics and Gynecology, Hannover Medical School, Carl-Neuberg-Str. 1, 30625, Hannover, Germany.

Purpose: Caesarean delivery (c-section) scar dehiscences may cause bleeding abnormalities, e.g. postmenstrual spotting, dysmenorrhea and abdominal pain, secondary sterility and at worst peripartum uterine rupture. The purpose of this study was firstly to identify the correlation of women's complaints after c-section with scar-related clinical symptoms. Secondly, the effects of corrective surgery on preoperatively existing complaints were analysed and assessed in the patient population of our clinic.

Methods: We present data of a retrospective study of 13 premenopausal, non-pregnant women with symptomatic c-section scars. In 9 out of 13 patients, a microsurgical uterus reconstruction was performed by mini-laparotomy. The postoperative changes of scar-associated symptoms were assessed by a questionnaire as earliest as 4 months after surgery (N = 5).

Results: The c-section scar was visualised by transvaginal sonography in 12 out of 13 women by a typical U- or V-shaped hypoechoic or anechoic fluid accumulation in the region of former uterotomy and in all 13 patients by hysteroscopy. Bleeding disorders were often accompanied by dysmenorrhea/abdominal pain (38.5%, N = 5) and secondary sterility (46.2%, N = 6). Blood residues in the scar pouch and bleeding disorders/postmenstrual spotting were found in 30.8% of patients (N = 4) and combined with secondary sterility in 38.5% of patients (N = 5). Reconstructive surgeries resulted in discontinuation of bleeding disorders in all women and a pregnancy in three out of five patients (60%) with secondary sterility.

Conclusion: Clinical symptoms, e.g. "bleeding disorders" like postmenstrual spotting, "pain/dysmenorrhea" and "secondary sterility" could be specific indicators for the diagnosis of uterine dehiscence after c-section. Scar dehiscences can be diagnosed by obtaining the patients medical history and asking for typical symptoms followed by vaginal sonography and diagnostic hysteroscopy. If a c-section scar defect is confirmed, microsurgical uterus reconstruction can stop postmenstrual spotting, reduce abdominal pain/dysmenorrhea and improve fertility.

Diagnostic challenges of hemihematocolpos and dysmenorrhea in adolescents: obstructed hemivagina, didelphys or bicornuate uterus and renal aplasia is a rare female genital malformation.

Arch Gynecol Obstet 2012 Sep 5;286(3):785-91. Epub 2012 Jun 5.

Department of Obstetrics, Gynecology and Reproductive Medicine, Hannover Medical School, Carl-Neuberg-Str. 1, 30625, Hannover, Germany.

Objectives: To develop a clear diagnostic and therapeutic strategy for adolescents presenting with abdominal pain and vaginal tumor caused by congenital female genital anomalies, such as blind hemivagina and uterine anomalies, as the lack of the correct diagnosis of the underlying anatomical genitourinary malformation frequently leads to destructive surgical procedures.

Methods: Retrospective study, study group: patients with double/bicornuate uterus, blind hemivagina and hematocolpos (n = 13), controls: patients with uterine malformation and complete vertical vaginal septum (n = 11), analysis for: menarche, age at onset of symptoms, type of malformation, symptoms leading to admission and diagnostic/surgical techniques applied.

Results: Median age at diagnosis study group 19.85 (SD ± 6.23, range 13-23 years) versus controls 26.09 years (SD ± 7.44, 16-36 years); predominance of imperforated hemivagina: 69.2 % right-sided versus 30.8 % left-sided septum; renal agenesis ipsilateral to imperforate hemivagina 100 % study group versus 9.1 % controls; 84.6 % previous surgical interventions in the study group, such as partial removal of the septum and re-obliteration, unilateral salpingo-ovarectomy and vaginal drainage of pyometra. We used a single transvaginal surgical procedure, including removal of the obstructed vaginal septum and marsupialization of the blind hemivagina.

Conclusions: A diagnostic and therapeutic algorithm for young women presenting with progressive dysmenorrhea and abdominal pain and/or vaginal tumor reduces destructive interventions.

The risk of ectopic pregnancy following tubal reconstructive microsurgery and assisted reproductive technology procedures.

Arch Gynecol Obstet 2012 Mar 24;285(3):863-71. Epub 2011 Sep 24.

Division of Reproductive Medicine, Department of Gynecology and Obstetrics, Medical School of Hannover, Carl-Neuberg-Str. 1, 30625 Hannover, Germany.

Purpose: The incidence of ectopic pregnancy (EP) in the general population is 2%, whereas the EP rate following assisted reproductive technologies (ART) is between 2.1 and 11%. EP is also an adverse effect of tubal surgery with incidences up to 40% depending on the type, location, and severity of tubal disease and the surgical procedure.

Methods: This paper looks at the incidence of EP following tubal reconstructive microsurgery, analyzes risk factors for EP following own 1,295 ART cycles and looks on the incidence of EP in 128,314 pregnancies following ART according to the presence or absence of tubal infertility using data from the German IVF Registry (DIR).

Results: In our clinic, the EP rate following resterilization was 6.7%. In the presence of acquired tubal disease, the EP rate following adhesiolysis, salpingostomy, salpingoneostomy, fimbrioplasty, and anastomosis was 7.9%. The EP rate following ART in our clinic was 5.6%. Previous abdominal surgeries, microsurgical procedures, hydro-/sactosalpinges, salpingitis, salpingitis isthmica nodosa, and periadnexal adhesions showed a significant positive correlation with EP as outcome. Data of DIR demonstrate a significantly increased incidence of EP in the presence of tubal pathology. The highest EP rate related to all clinical pregnancies was 4.5% (95% CI 3.0-6.0) in smoking women <30 years with tubal pathology following IVF.

Conclusions: In the presence of tubal infertility, the incidence of EP following ART and tubal microsurgery are approximately comparable with each other and higher than in women without tubal infertility. The success of infertility surgery depends on a careful selection of appropriate patients.

Is there still a role for reconstructive microsurgery in tubal infertility?

Curr Opin Obstet Gynecol 2011 Jun;23(3):200-5

Division of Reproductive Medicine, Department of Gynecology and Obstetrics, Medical School of Hannover, Germany.

Purpose Of Review: To review the current role of tubal reconstructive surgery in the era of assisted reproductive techniques (ARTs).

Recent Findings: After tubal reconstructive surgery, couples may have unlimited attempts to conceive naturally. Operative risks are low; the risk for ectopic pregnancy after surgery is 4-10%. ART is associated with a number of potential complications: severe ovarian hyperstimulation syndrome (0.25-2%), multiple pregnancies (up to 25%), a higher rate of major malformations and stillbirths, and ectopic pregnancy (1-13%). Birth rates following ART differ between 19 and 35%, depending on different laws governing the fertilization of a limited number of oocytes and the number of embryos transferred. Resterilization is a main indication for microsurgery with resulting pregnancy rates up to 84%. Salpingostomy and dense adhesiolysis have the lowest success rates (term pregnancy rates: 3-65%). Proximal tubal obstructions can be successfully treated by tubocornual anastomosis. Hydrosalpinges should be removed prior to in-vitro fertilization if they cannot be reconstructed. ART is recommended for patients older than 37-38 years, for women with severe tubal pathology, after repeated ectopic pregnancies, and in case of male infertility.

Summary: Tubal reconstructive surgery still plays a role in infertility treatment. ART has not replaced microsurgery routinely as first-line treatment for tubal infertility.

Organ-preserving and reconstructive microsurgery of the fallopian tubes in tubal infertility: still an alternative to in vitro fertilization (IVF).

J Reconstr Microsurg 2010 Jul 1;26(5):317-23. Epub 2010 Mar 1.

Department of Gynecology and Obstetrics, Division of Reproductive Medicine, Medical School of Hannover, Hannover, Germany.

Tubal infertility mostly results from infections. Conception only is possible through complex treatments (in vitro fertilization or surgery). Success cannot be guaranteed, even after repeated treatments. Unfortunately, many couples are not informed about the prospect for success of tubal reconstruction. Problems of in vitro fertilization are low pregnancy and birth rates of 28.4% and <20% respectively (Germany) and the high number of multiple pregnancies (21%). In this retrospective study 462 women with acquired tubal infertility and further 127 women after previous sterilization underwent microsurgical treatment (microsurgical adhesiolysis, anastomosis, fimbrioplasty, salpingostomy, and refertilization due to former sterilization). The main outcome measures are the pregnancy and birth rates following the microsurgical procedure. Pregnancy and birth rates of 43.4% and 29.2%, respectively, were higher than the outcomes post-single in vitro fertilization (abortion: 6.4%, extrauterine pregnancy: 7.9%). When reversal of sterilization was performed, pregnancy and birth rates were higher at 73% and 50.6%, respectively (abortion: 15.7%, extrauterine pregnancy: 6.7%). The advantages of reconstructive microsurgery over in vitro fertilization include the ideally permanent restoration of woman's ability to conceive naturally (repeated pregnancies are possible without further therapy), a high postoperative birth rate overall, and avoidance of multiple births. It is advisable to inform the patient about the objective possibility of reconstructive tubal surgery.

Reconstructive, organ-preserving microsurgery in tubal infertility: still an alternative to in vitro fertilization.

Fertil Steril 2010 Mar 26;93(4):1359-61. Epub 2009 Sep 26.

Department of Obstetrics and Gynecology, Division of Reproductive Medicine, OE 6410, Hannover Medical School, Carl-Neuberg-Str. 1, 30625 Hannover, Germany.

In this retrospective study, we observed a total of 553 patients with tubal infertility who underwent microsurgical reconstructive surgery of the fallopian tubes (including adhesiolysis, anastomosis, fimbrioplasty, salpingostomy, and refertilization after former sterilization). The pregnancy (43.4%) and birth (29.2%) rates after microsurgery for acquired tubal damages (abortion: 6.4%; ectopic pregnancy: 7.9%) were higher than after single in vitro fertilization (28.4% and <20%, respectively; data from German IVF register). The pregnancy (73%) and birth (50.6%) rates after the reversal of sterilization also were higher (abortion: 15.7%; ectopic pregnancy: 6.7%). The advantages of reconstructive microsurgery over in vitro fertilization include the ideally permanent restoration of a woman's ability to conceive naturally in every cycle that she ovulates, a high postoperative birth rate overall, and avoidance of multiple births.
