Primary Torsion of Lesser Omentum Presented with Acute Abdomen and Successfully Managed with Laparoscopic Surgery

To the Editor: Omental torsion can be classified as primary or secondary according to etiology and may be localized in the greater or lesser omentum. Primary torsion of the omentum is characterized with the absence of associated intra-abdominal pathology; however, secondary torsion of the omentum can be associated with underlying factors, including cysts, tumors, foci of intra-abdominal inflammation, postsurgical scars, and hernia sac.[1,2] Omental torsion is a relatively rare cause of an acute abdomen, which often needs surgical management. The pathogenesis of omental torsion has not yet been fully established.[1] Since omental torsion presents with various clinical features, such as no symptom, nonspecific abdominal symptoms, and signs of an acute abdomen, it must be distinguished from other causes of acute abdominal pain, such as cholecystitis, diverticulitis, appendicitis, and other intra-abdominal inflammatory conditions.
