[Possibilities of gastroscopy after the surgical treatment of peptic ulcer].

A considerable diagnostic value of endoscopy for the detection of recurrent ulcers and other postoperative syndromes was shown on the basis of the experience with endoscopies in 21 patients after gastroenterostomies , 281 patients after gastric resection and 96 patients after vagotomies performed for the ulcer disease of the stomach and duodenum. The methods of examining and the endoscopic picture after different operations are found to be of particular character. To study the state of the afferent loop after Bilroth -II resection of the stomach it is expedient to associate endoscopy with rentgenological examination. Endoscopy can be also used for some postoperative complications.
