Intersigmoid hernia. A forgotten diagnosis. A systematic review of the literature over anatomical, diagnostic, surgical, and medicolegal aspects

Intersigmoid hernia is a hernia 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 intersigmoid hernias is difficult and the diagnosis is often confirmed during the laparotomic exploration. Due to the vague clinical manifestation in most cases, the surgical treatment is frequently delayed.
