Internal abdominal hernia is an unusual cause of intestinal obstruction. Paraduodenal hernia is relatively rare congenital malformations resulting from incomplete rotation of the midgut with entrapment of the small intestine beneath the developing colon. We report a case of paraduodenal hernia treated by laparoscopic approach. The patient was a 45-year-old man presenting with severe abdominal pain for 5 hours. Left paraduodenal hernia with jejunum hernia containing jejunal loops showed in abdominal CT. At operation, herniation of the small intestine into a retroperitoneal space through a defect on the left mesocolon was noted. After the herniated bowel was fully reduced, the hernia orifice was closed intra-corporeally in the manner of interrupted sutures with absorbable suture materials. The patient was discharged home without any serious complications on postoperative day 9. Conclusively, we think laparoscopic surgery in left paraduodenal hernia is feasible.
