RÉSUMÉ
In the cases where a primary anastomosis is unable after a duodenal resection, special care must be taken to avoid any complication in the duodenal stump such as suture dehiscence. Wall inflammation is an important factor in the development of this complication. We report a case of a 35-year-old woman who had previously undergone to pyloric exclusion due to a wall defect occurred after a bilio-digestive anastomosis, which complicated with a posterior duodenal stump dehiscence. The acute edema of the stump walls that resulted after it because exposure to bile conducted to heroic measures for its closure: first, the use of a polytetrafluoroethylene tube as duodenostomy and posteriorly a patch of the same material for its final closure. Both gave successful results in the repair of a refractory duodenal stump dehiscence.
