[Internal ligatures of the pyloro-duodenal region after surgical treatment of bleeding ulcers].

1886 fibrogastroduodenoscopic examinations were performed in 820 patients within 7 years after operative treatment of bleeding pyloroduodenal ulcers. Catgut was used in 589 patients for internal sutures in pyloroplasty, the unresolving suture material--capron--was used in 221 patients. Clinico-endoscopic investigations have shown that the application of catgut is followed in the early postoperative period by the development of inflammatory reactions in the tissues along the suture line, while the use of the unresolving suture material is followed by inflammations of less degree, the rejection of internal ligatures was slow with episodes of bleedings, ulcerations, formation of granulomas. The article gives grounds for expedience of removal of internal ligatures during the endoscopic examination of organs in the zone of the operative intervention.
