[Adenocarcinoma of the duodenojejunal angle. Diagnostic and therapeutic problems].

The duodenojejunal is a rare site for the development of tumors. Diagnosis is difficult but two cases are reported in which the presence of a tumor was determined by small intestine follow through radiography and confirmed on endoscopy. Surgical treatment is limited by size of lesion. The two cases reported were treated by resection and the patients have survived for 8 months and 5 years respectively.
