Internal abdominal hernias are an unusual cause of intestinal occlusion. They are responsible for 2% of all the intestinal obstructions. Various types of hernia have been described. Paraduodenal hernias are relatively rare congenital malformations and result from incomplete rotation of the midgut with entrapment of the small intestine beneath the developing colon. We report a case of paraduodenal hernia of the small intestine in a 32-year-old man with presentation of intestinal obstruction. The patient suffered from nausea, vomiting and acute abdominal pain for 9 hours. Abdominal CT showed sac-like mass of clustered, dilatated small bowel in the right upper quadrant. At operation, herniation of small intestine into a retroperitoneal space through a defect on right mesocolon was noted. A right paraduodenal (mesocolic) hernia was diagnosed. The patient made an uneventful recovery except some diarrhea after extensive segmental resectio of strangulated small bowel. Paraduodenal hernia is important as it usually presents as intestinal obstruction, and is often misdiagnosed before laparotomy. Mortality is increased significantly with delays in surgical treatment. Though rare, paraduodenal hernia should be taken into account in a differential diagnosis of intestinal obstruction. Early surgical intervention allows uneventful recovery and also prevents the possible complication of gangrenous bowels.
