Paraduodenal hernia: a rare cause of abdominal pain

I nternal abdominal hernias are rare conditions, accounting for 0.9% of all intestinal obstructions.1 Paraduodenal hernias constitute half of all internal abdominal hernias. They occur when the small bowel herniates into the paraduodenal fossa and can manifest as intestinal obstruction.2 Herniation into the left paraduodenal fossa (fossa of Landzert) occurs more frequently than herniation into the right fossa (fossa of Kolb).3 Clinical diagnosis is difficult. We report the case of a left paraduodenal hernia as a coincidental finding in a patient who underwent a laparotomy for a suspected sigmoid tumour.
