Internal herniation following laparoscopic pancreatoduodenectomy.

Laparoscopic pancreatoduodenectomy (LPD) is increasingly performed worldwide as an alternative to the open conventional method, with the aim of advancing recovery. Because of its recent introduction, little is known about late surgical complications from this procedure. Here, we describe a case of a 76-year-old woman who underwent LPD with end-to-side gastrojejunostomy and presented with pain in the right upper quadrant of the abdomen 6 months thereafter. CT showed signs of an internal herniation. Elective diagnostic laparoscopy demonstrated a hernia of the efferent loop in Petersen's space. The loop was repositioned and Petersen's space was closed. The patient was discharged on the same day. Apart from a short readmission for nausea and vomiting, which were managed conservatively, the patient recovered without any further complications. Internal herniation should be considered in patients with abdominal complaints following LPD.
