A rare laparoscopic diagnosis in acute abdominal pain: torsion of epiploic appendix

Torsion of an epiploic appendix is seldom diagnosed preoperatively because of the difficult differential diagnosis with other diseases causing acute abdominal pain, particularly appendicitis. The classic McBurney approach overlooks many infarcted epiploic appendixes. The use of diagnostic laparoscopy in acute abdominal pain can show an infarcted epiploic appendix to be at the origin of pain. Four patients were admitted for acute abdominal pain and moderate tenderness in lower quadrants and were operated on for suspected acute appendicitis. In all cases laparoscopy found the torsion of an epiploic appendix, which was resected, and a normal cecal appendix. Postoperative course was uneventful. In case of acute abdominal pain in the lower quadrants of suspected appendiceal origin, laparoscopy should be routinely performed not only in women but also in men to avoid overlooking other intraperitoneal diseases that can be the cause of symptoms.
