Intersigmoid hernia: A rare cause of acute intestinal obstruction

Abstract

Intersigmoid hernia (ISH) is a protrusion of the small bowel into the intersigmoid fossa. It is well known to be a rare condition. Recent reports reveal that the preoperative differentiation of ISHs is difficult and the diagnosis is often confirmed during the laparotomic exploration. This article reports a case of an ISH presenting with symptoms of bowel obstruction. Computed tomography scan revealed that dilated small bowel loops are probably related to an incarcerated ileal retrocolic loop in left iliac fossa. This case was confirmed at surgery.
