A 39-year-old woman was admitted to the hospital because of acute abdomen. Abdominal CT scan at arrival showed mobile of the descending colon and dilation of the small intestine between the stomach and pancreatic body and tail. Abdominal CT scan at abdominal attack showed the dilated small intestine that converged toward the inferior mesentric vein (IMV). Therefore she was diagnosed as having left paraduodenal hernia with mobile of the descending colon. Laparotomy showed mobile of the descending colon and the entire small intestine except for the end of the ileum that which was dislocated to the left side of the descending colon passed from behind the IMV. The small intestine by 110cm from the Treitz ligament was covered with hernial sac, and the remaining small intestine was uncovered. After the intestine was repositioned, the descending colon was fixed and a deficit on the mesentery of descending colon was closed. Left paraduodenal hernia usually has a hilum of which anterior wall consist of IMV, so this case was diagnosed as left paraduodenal hernia with two components with and without hernial sac.
