[A case of left paraduodenal hernia combined with acute small bowel obstruction].

Paraduodenal hernias are rare congenital malrotational anomalies of midgut that arise in the potential spaces and folds of the posterior parietal peritoneum adjacent to the ligament of Treitz and can lead to intestinal obstruction. Also, they have shown several presentation patterns, such as asymptomatic, chronic intermittent abdominal pain, and acute severe abdominal pain. If symptomatic hernias with strangulation are untreated, according to the previous reports, they lead to overall mortality exceeding 50%. We report a case of the left paraduodenal hernia combined with small bowel obstruction from the patient who had no history of surgery before and developed abdominal pain after drinking of alcohol heavily. Abdominal CT scan showed sac-like mass of clustered in the left upper quadrant. The patient underwent the surgery of the bowel reduction and adhesiolysis and got uneventful recovery.
