[ XXXX after gastric operations (author's transl)].

@entity1 @entity189
The incidence of @entity189 after gastric operations for benign lesions was analysed in the @entity1 material of five gastroenterologists in private practice in Switzerland. Of 534 such @entity1 346 had had a gastric resection with gastrojejunostomy (Billroth II), 58 with gastroduodenostomy (Billroth I), and 130 other kinds of gastric operations. Among 326 @entity1 who had a Billroth II procedure there were 21 with proven @entity189 in the residual stomach, but none after Billroth I and other operations. The incidence after Billroth II was 15.1% at or after ten years. Of 69 @entity1 10-19 years after gastric resection, six had developed @entity189 , compared with 15 of 70 who were 20 years or more after the resection. The incidence is unexpectedly high. On the other hand, among 29361 non-operated @entity1 there were 279 with @entity189 . The average interval between operation and the diagnosis of @entity189 in the residual stomach was 23.8 years. It is recommended that gastric resection should if possible be avoided for benign disease. All @entity1 who have had a gastric resection should be endoscopically controlled annually from ten years after the resection onwards.
