[The incidence of gastric carcinoma after gastrectomy for peptic ulcer in the Vigo region. A case-control study].

After reviewing 10,000 upper gastrointestinal endoscopies performed at the endoscopy unit of the city of Vigo over a 38 month period, we have found 485 partial gastric resections for peptic ulcer, 357 gastric carcinomas were found, of which 26 occurred after partial gastric resection for peptic ulcer. Therefore the incidence of gastric cancer in this area was 22-23/100,000. The frequency of gastric cancer after partial resective surgery was lower than expected during the first 20 years after surgery. However, thereafter a significant increase of gastric cancer occurred in those patients in which a Billroth-II but not Billroth-I procedure was used.
