[Indication for treatment of gastric and duodenal ulcers by resection (BI/II) (author's transl)].

After exposing the indications for resections according to Billroth, the results achieved are analysed, advantages and disadvantages of the method are discussed with regard to late results. A strict indication lowers the motality rate, postprandial disorders, anastomotic ulceration and carcinoma of the gastric stump. New operative methods like vagotomy and its modifications should complete the surgical armamentarium, but cannot replace the classic gastric resection.
