Association of pediatric inguinal hernia contents with patient age and sex.

Pediatr Int 2022 Jan;64(1):e15193

Department of Digestive and General Surgery, Shimane University Faculty of Medicine, Izumo, Shimane, Japan.

Background: Although pediatric inguinal hernia (IH) is a very common disease, systematic reviews of herniated organs are scarce. The current study aims to clarify the contents of pediatric IH using preoperative ultrasonography (US) in association with patient age, sex, and risk for developing irreducible/strangulated hernia.

Methods: The medical records of pediatric IH patients who underwent inguinal US examination prior to surgery between 2014 and 2019 were reviewed. Read More

Microcystic stromal tumor of the ovary: a recurrent case with somatic CTNNB1 missense mutation.

Virchows Arch 2022 Jun 14. Epub 2022 Jun 14.

Department of Gynecology, National Cancer Center Hospital, 5-1-1 Tsukiji, Chuo-ku, Tokyo, 104-0045, Japan.

Microcystic stromal tumors (MCSTs) of the ovary are rare sex cord-stromal tumors that are considered benign neoplasms because almost all cases display unilateral, localized lesions and have benign outcomes, except for one recurrent case with familial adenomatous polyposis and another initial metastatic case with a CTNNB1 mutation. We report herein a sporadic case that relapsed as intra-abdominal spread 9 years and 1 month after primary left salpingo-oophorectomy for torsion of the ovarian tumor pedicle. The tumor relapsed as multiple disseminations at the subabdominal wall, Douglas pouch, and omentum. Read More

Omental torsion at the time of COVID-19 in Northern Italy: a case report of conservative management with a review of the pertinent literature.

Acta Biomed 2022 04 14;93(S1):e2022123. Epub 2022 Apr 14.

.

Background And Aim: In middle-aged men, omental torsion (OT) can be a cause of acute abdomen.The right side of the omentum is longer, heavier and more mobile than the left one and, as a consequence, it can twist more easily on its vascular axis. Consequently, OT localization in the lower right quadrant is more frequent, and therefore it can mimic acute appendicitis clinical onset. Read More

J Investig Med High Impact Case Rep 2022 Jan-Dec;10:23247096221076271

Wayne State University, Detroit, MI, USA.

Acute abdomen is a common emergency condition affecting young adults, and the first consideration is usually aimed to rule out acute appendicitis in this age group. Omental fat torsion has emerged as one of the rare etiologies of acute abdomen in the younger population. It warrants serious consideration as it closely mimics acute appendicitis in its clinical presentation. Read More

Falciform Ligament Torsion Caused by Omental Hernia Through the Foramen of Morgagni.

Curr Med Imaging 2022 ;18(6):689-691

Department of Radiology, Faculty of Medicine, Hacettepe University, Ankara, Turkey.

Introduction: Torsion of the falciform ligament, one of the rarest causes of acute abdominal pain, often presents with pain in the right upper quadrant and epigastrium.

Case Presentation: In this case, we present the Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) findings of torsion of the falciform ligament that occurred in the presence of omental fat herniation through the foramen of Morgagni in an 88-year-old female patient who presented to the emergency department with acute epigastric pain.

Conclusion: Torsion of the falciform ligament may develop secondary to omental hernia in the setting of Morgagni hernia and should be taken into consideration as one of the rarest causes of acute abdominal pain, even in elderly patients. Read More

Extragonadal teratomas in women and adolescent girls: A systematic review.

Eur J Obstet Gynecol Reprod Biol 2021 Jul 7;262:134-141. Epub 2021 May 7.

Department of Obstetrics and Gynaecology, National University Hospital, 5 Lower Ridge Road, 119074, Singapore. Electronic address:

Introduction: Extragonadal teratomas (EGTs) are rare and the commonest intra-abdominal subtype is omental. We present two cases: 1) a parasitic omental teratoma likely secondary to auto-amputation of an ovarian teratoma with subsequent omental reimplantation and 2) an omental immature teratoma likely due to parthenogenetic activation of displaced primordial germ cells. We subsequently conduct a systematic review to characterise EGTs. Read More

Laparoscopic Management of Primary Omental Torsion.

Case Rep Surg 2021 24;2021:5536178. Epub 2021 Feb 24.

Centre Hospitalier Sud Francilien, Corbeil-Essonnes, France.

Primary omental torsion is an unusual condition, known for its rarity and for the particularity of being intraoperatively diagnosed, in nearly all cases. At the clinical evaluation, this pathology commonly mimics other etiologies of acute abdomen. Hemoperitoneum and necrosis of the omentum are rarely associated with the omental torsion, but when the association is found, then it means that the vascular injuries are irreversible and the required surgical procedure may be far more complex than simple devolvulus.
