Abstract
Left paraduodenal hernia is a congenital internal hernia rarely complicated by acute intestinal occlusion and resulting, sometimes, in life-threatening loops ischemia. We report the case of a 28-year old man treated for occlusive syndrome. Abdominal computerized tomography (CT) scan objectified acute upper intestinal obstruction; intraoperative exploration found jejunal loops incarcerated into left paraduodenal hernia. The neck was closed and the operative suites were simple. Left paraduodenal hernia is often diagnosed when patients have complications. Surgery is the treatment of choice, in particular laparoscopy.
