[Left paraduodenal hernia: a rare cause of acute intestinal obstruction].

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.
