Isolated omental panniculitis (IOP), a rare form of acute abdominal syndrome, is defined as intraabdominal panniculitis that involves only omentum without extraabdominal fat necrosis, inflammatory bowel disease and pancreatitis. In the search made using PubMed English database, only 4 cases are determined with IOP. IOP is conceptually confused with idiopathic omental infarction (IOI). However, omental infarctions that are rare causes of acute abdominal syndromes were published by Bush for the first time in 1986 and less than 400 cases were reported. In this article we aimed to publish 2 IOP patients who applied with acute abdominal manifestation and were treated with laparoscopic omental resection to discuss the other 4 IOP cases comparing with IOP together with literature.
