[What is certain in the pathogenesis and incidence of primary carcinoma involving the operated stomach?].

It has been postulated that resection therapy for peptic ulcer disease will result in an increased frequency of gastric stump cancer depending on the ulcer type and type of operation (Billroth I, Billroth II, gastroenterostomy). However, an extensive review of the literature shows that after Billroth II resection for gastric ulcer without enteroanastomosis the frequency of primary gastric stump cancer is not greater than in the case of medically treated benign gastric ulcers. The frequency of cancer of the gastric stump seems lower after resection for duodenal ulcer disease. It is possible that the combination of the Billroth II resection with an enteroanastomosis decreases the frequency of cancer of the gastric remnant. Clinical and experimental studies do not allow final statements on cancer frequency after Billroth I resection or simple gastroenterostomy.
