Duodenojejunostomy in gastric operations for postbulbar duodenal ulcer

In two cases, two different techniques of duodenojejunostomy were employed as an alternative to an insecure closure of the "difficult duodenal stump." The arrangements are either duodenojejunostomy Roux-en-Y or isoperistaltic jejunal interposition. A single-layered suture line is employed. The ampulla of Vater is visualized during the construction of these anastomoses. In addition to obviating a tenuous stump closure, this technique has the theoretical advantage of providing internal drainage.
