[The causes of incompetence of the duodenal stump and gastroenteric anastomosis and the means for its prevention in the surgery of duodenal ulcers].

Causes of the incompetence of stump sutures in resection of the stomach observed in 90 out of 3479 patients with chronic duodenal ulcers were analyzed. Most patients were found to have a combination of general and local factors. Among the local factors the leading one was appearance of a large inflammatory infiltration around the "active" ulcers. The endoscopic autohemoapplication to the ulcer included in the complex of preoperative preparation of the patients reduced the frequency of incompetence of sutures from 2.58% to 1.33%.
