[Inguinal herniation of a tubular duplication of the ascending colon (author's transl)].

A 6-year-old boy is reported who was operated upon with a pre-operative diagnosis of a recurrent right incarcerated inguinal hernia. As green-brown fluid appeared from the suspected hernial sac, a laparotomy was performed which showed a duplication of the ascending colon with a prolongation into the inguinal canal. The duplication and the relative intestinal segment were excised (right-sided) and because of the close relationship between the intestinal wall and the wall of the cyst, and the shared blood supply, an organ procedure was technically not possible.
