A 13-year-old girl visited our hospital with persistent abdominal pain and vomiting. Abdominal CT scans revealed a cluster of small bowel loops on the left side of the ligament of Treitz. The patient was diagnosed as having a left paraduodenal hernia, and an emergency laparoscopic operation was performed. Herniation of the jejunum was observed into the dorsal side of the inferior mesenteric vein through a hernia orifice located at the left side of the ligament of Treitz. Furthermore the jejunum-comprising the content of the hernia had penetrated the hernia sac and prolapsed into the abdominal cavity. The jejunum which was incarcerated was reducted possibly by traction. The hernia orifice was laparoscopically sutured. A paraduodenal hernia is categorized into a retroperitoneal hernia. Cases in which the hernia sac has collapsed and the small bowel has penetrated the hernia sac are rare. Laparoscopic surgery for the paraduodenal hernia made diagnosis and treatment possible with its good field of view．We have gained an extremely favourable impression of this procedure.
