Left Paraduodenal Hernia-A Rare Cause of Acute Abdomen

Para Duodenal Hernia, the most common type of internal hernia, is a rare cause of abdominal pain and an uncommon aetiology of intestinal obstruction. It arises from the error of mid-gut rotation during fixation of the mesentery to posterior abdominal wall. Duodenum and small intestine become trapped in a peritoneal sac behind the mesentery of the colon either to the right or left of midline. High suspicion is required in a young male with no history of previous abdominal surgery, and computed tomography (CT) scan of the abdomen can make preoperative diagnosis. Laparoscopy/laparotomy is the choice of treatment. We report a case of left Para Duodenal Hernia (LPDH) in a 48-yearmale complaining of abdominal pain with no history of previous abdominal surgery. LPDH was diagnosed with a CT scan, which showed encapsulated sac, situated to the left of ligament of Treitz, behind the stomach and pancreas, containing jejunal and few ileal loops. Laparotomy was done. Reduction of hernia, plication of hernial sac and suturing of the edges of hernial sac to posterior abdominal wall was done. The patient had uneventful recovery within 8 days.
