[Paraduodenal hernia: 3 cases and revue of the literature (author's transl)]. / Les hernies paraduodénales. Revue de la littérature à propos de 3 cas.

Three cases of surgically treated para-duodenal hernia are presented. The literature is reviewed. Several modalities of this entity are described as well as the embryological hypotheses to explain their genesis. The diagnosis is usually made at the time of a laparotomy for bowel obstruction. The surgical manipulations to reduce the hernia content (one or several loops of small bowel) are discussed.
