Short- and long-term results of isolated selective proximal vagotomy (SPV) performed at non-complicated duodenal ulcer and SPV with duodenoplastic and drainage surgeries at ulcerous pyloroduodenal stenosis were analyzed. Principles of choice of duodenoplastic and drainage surgeries are discussed. Six variants of duodenoplasty is used depending on anatomic characteristics and localization of stenosis. Advantage of duodenoplasty over drainage surgeries is demonstrated. It is concluded that SPV with duodenoplasty should be regarded as surgical method of choice at the treatment of ulcerous duodenal stenosis because of low rate of stomach and duodenum functional disorders at long-term period after surgery.
