Laparoscopic omental resection for omental infarction: a case report

Omentum is a medical term referring to layers of peritoneum that surround abdominal organs. Acute abdominal pain due to omental necrosis is rare with the incidence of less than 0.4% cases of appendicitis. In most cases, omental infarction was caused by rotation, torsion of the omentum, or abdominal infection which induces an obstruction of vessels and leads to omental necrosis. Clinical manifestations were nonspecific. All most cases, infarction of the greater omentum was diagnosed only during emergency surgery for other diseases of the abdomen such as cholecystitis, appendicitis, or peptic ulcer perforation. Nowadays, multi-sequence computed tomography was taken for acute abdomen, more and more this disease being diagnosed preoperatively. We report patient who were referred to our emergency department for right lower quadrant abdominal pain. Computed tomography (CT) scan showed signs of infiltration, thickening of the omentum. We underwent an emergency laparoscopic to abdominal cavity exploration. The patient was discharged after three days. Laparoscopic omentectomy should be performed as soon as possible with good results.
