[Duodenal duplications. Apropos of 3 cases].

The treatment of three cases of double duodenum and review of 30 cases from the literature show the excess of certain surgical attitudes. Duplication is a benign lesion, most often found in the infant or newborn and for which treatment must remain simple. Mutilating excision procedures should be avoided: gastroduodenectomy, duodenopancreatectomy. Total resection, which is rarely possible, or subtotal resection with destruction of active mucosae, and internal duodenal or rarely jejunal bypasses are satisfactory forms of treatment in the immense majority of cases.
