Abstract
Primary greater omental torsion is a rare cause of acute abdomen extremely difficult to identify preoperatively. We report three cases of primary omental torsion diagnosed preoperatively, discussing diagnostic and therapeutic aspects. Case 1: A 57–year–old man was admitted with upper right abdominal pain. Case 2: A 52–year–old man reported lower right abdominal pain. Case 3: A 39–year–old man reported epigastralgia. Abdominal computed tomography (CT) in all cases showed a preoperative whirl pattern of fatty streaks and vessels within the greater omentum secondary to torsion —the whirl sign and concentric linear strands. All cases were treated laparoscopically. Operative findings showed a necrotic omental mass closed where the entire greater omentum had undergone torsion. All recovered uneventfully, confirming laparoscopic surgery safety and effectiveness in promptly diagnosing and treating those with acute abdominal symptoms.
