Laparoscopic Repair of Small Bowel Obstruction Caused by an Intersigmoid Hernia: A Case Report

Bowel obstructions can be caused by internal hernias which are protrusions of the bowel into openings within the abdominal cavity. There are various types of internal hernias including sigmoid hernias which involve the sigmoid mesentery.Sigmoid hernias are very difficult to diagnose clinically, even with the aid of radiologic imaging. Computed tomography (CT) scan findings often reveal small bowel obstructions; however, they are not sensitive to intersigmoid hernias. Most of these rare herniations are repaired by open abdominal surgery followed by the closure of the mesenteric defect to prevent a recurrence. We present the case of a 57-year-old man who presented to the emergency department with a small bowel obstruction that was caused by an intersigmoid hernia and was successfully repaired through a minimally invasive laparoscopic approach. This case demonstrates an intra-operative diagnosis of an intersigmoid hernia and reviews the benefits of a laparoscopic approach for the reduction of the sigmoid mesentery.
