Abstract
Twenty patients with duodenal ulcer were treated by pylorus-preserving gastrectomy. Post operative reduction in maximal acid output was 65%. Gastric emptying was slow without producing stasis. A provocative test showed that dumping was almost completely eliminated and was very mild in the one case in which it did occur. Short-term review between 2 and 3 years postoperatively showed continuing satisfactory results with no gastric stasis and an absence of early recurrence. The results are compared with the results of proximal selective vagotomy, and the mechanism of maintenance of a functioning pylorus is discussed.
