[The surgical treatment of chronic duodenal obstruction].
An analysis of indications to operative treatment has been made on the basis of clinical examinations of 162 patients with chronic disturbances of duodenal patency. The operation is indicated to patients with mechanical forms with any stage and to all the patients with the stage of subcompensation and decompensation. Operations were performed on 98 patients. In patients with the stage of subcompensation the operations were most effective which excluded the duodenal passage, especially antrumectomy after Roux with the elimination of the mechanical obstacles at the level of the duodenojejunal passage. At the stage of decompensation only such combined operations are thought to be effective which include additional drainage of the excluded duodenum.
