[The technical modalities of duodenojejunoplasty in large parietal defects of the duodenum].

The authors present two technical modalities for solving extensive defects of the duodenal wall which occurred during surgery for large duodenal ulcers, which in one case involved the entire anterior part of D1-D2. In another case the duodenal wall defect was due to tumoral invasion by cancer of the hepatic angle of the colon. The solution consisted in duodenoplasty with excluded intestinal loop in "Y", in the first case, and duodenoplasty on an omega loop associated with GEP in the second case.
