Pyloroplasty for the unusual perforated duodenal ulcer.

The performance of a large number of pyloroplasties upon patients with perforated duodenal ulcers gave us an opportunity to observe some instances of unusual perforations of the superior duodenal border from ulcers of the posterior wall. A technique of treating these very severe ulcerations without antral resection by pyloroplasty is described herein. Eighteen patients have been operated upon without mortality up to December 1978.
