title: An unusual cause of acute abdominal pain after cardiac surgery: acute epiploic appendagitis.
abstract: Abdominal complications following cardiac surgery remain unusual, but are associated with high mortality. The most common abdominal surgical complications are mesenteric ischaemia, diverticulitis, pancreatitis, gastrointestinal bleeding and cholecystitis. We describe a case of a 73-year old woman with acute abdominal pain mimicking cholecystitis on day 10 after aortic valve replacement. An abdominal examination showed tenderness of the right upper quadrant with Murphy's sign. Complete blood count, blood chemistries and urinalysis were normal as were the abdominal and chest X-rays and abdominal ultrasonography. The abdominal computed-tomography (CT) scan enabled us to rule out cholecystitis, as it demonstrated the typical appearance of epiploic appendagitis on the right colon, 1 cm below the gallbladder. Epiploic appendagitis results from twisting, kinking or venous thrombosis of an epiploic appendage. Depending on its localization, it mimics many diagnoses requiring surgery: colitis, diverticulitis, appendicitis and cholecystitis. An abdominal CT scan is the diagnostic imaging tool of choice. All physicians involved in post-cardiac surgery care should be aware of this self-limiting disease that usually resolves with non-steroidal anti-inflammatory drugs and watchful waiting, and to avoid unnecessary surgery because the spontaneous evolution of epiploic appendagitis is usually benign.
