Rare cause of chronic abdominal pain: left paraduodenal hernia and its surgical management

A 30-year-old man presented with colicky abdominal pain for 2 months, associated with occasional episodes of bilious vomiting. He had a history of similar complaints at the age of 16 and 26 years. Contrast-enhanced computed tomography abdomen was consistent with a diagnosis of left paraduodenal hernia. On laparoscopy a 3 x 3 cm hernial defect was identified in the left paraduodenal fossa (fossa of Landzert). Contents were jejunal, and proximal ileal loops which were dilated and edematous. Anterior border of the sac was formed by the inferior mesenteric vein and left branch of the left colic artery. Initial reduction of contents was easy. However, complete reduction proved to be difficult due to adhesions with the sac opening, the hernial sac instead laid open by dividing the Inferior Mesentric Vein (IMV) (anterior border of defect) using a vascular stapler. The patient was discharged on postoperative day 3 in a stable condition. On follow-up the patient is doing well.
