Acute primary haemorrhagic omental torsion is an atypical and deceptive cause of acute abdomen that could closely mimic a myriad of intra-abdominal catastrophes, especially perforated appendicitis. The author reports a 30 years man who had presented with gradually worsening right-sided abdominal pain of 2 days duration. Laboratory work-up and abdominal radiographs were inconclusive. Abdominal s...

Introduction. Laparoscopic Roux-en-Y gastric bypass (LRYGBP) is a common procedure in obesity surgery. The aim of an antecolic approach is to reduce the rate of internal herniation. Our aim is to make bariatric surgeons aware of another possible complication of antecolic LRYGBP. Methods and Results. We present a case report of omental torsion 24 months after antecolic LRYGBP presenting as an ac...

Omental torsion is a rare cause of acute abdominal pain. It presents with nonspecific symptoms and signs of an acute abdomen, making it difficult to diagnose preoperatively, because symptoms mimic those caused by other conditions such as appendicitis, cholecystitis, diverticulitis, and other gynecologic diseases. Computed tomography is an effective and useful method to diagnose and exclude othe...

Omental infarction is an uncommon but important cause of acute abdominal pain, which frequently mimics other surgical presentations. The current series describes five cases of idiopathic omental torsion and infarction and provides a review of the literature. We discuss the diagnosis of primary omental infarction as well as the role of conservative and surgical management.

Background. Torsion of greater omentum is a quite uncommon cause of acute abdomen. It can be primary or secondary but in both cases omentum twists upon itself and causes omental segmentary or diffuse necrosis. Symptoms are unspecific and preoperative diagnosis is difficult. The widespread and increasing use of computer tomography (CT) in differential diagnosis of acute abdomen can be useful for...

Omental torsion is an infrecuent cause of acute abdomen. It is related to obesity, abdominal surgery and abdominal trauma. Urgent exploratory laparotomy allows diagnosis and prevents complications as intrabdominal abcess. We present CT imaging of a Omenat torsion clinical case.

Omental torsion is caused by the rotation of the greater omentum on its axis which may lead to tissue infarction and necrosis. It is a rare cause of acute abdomen. Signs, symptoms and paraclinical data are not specific. The patients usually undergo laparotomy for acute abdomen of poorly defined origin. High index of suspicious is required for the diagnosis of this entity. The diagnosis is usual...

Omental torsion is an underdiagnosed cause of acute abdomen in children. Most cases occur in adults, with only 15% presenting in children. It is estimated that omental infarct is found in approximately 0.1 to 0.5% of children undergoing operations for appendicitis. It may present with various signs and symptoms, although the clinical presentation usually mimics that of acute appendicitis. Defin...
