[Pathogenesis and clinics of gastric stump carcinoma (author's transl)].

Statistics of postmortem examinations and retrospective long-term observations indicate a disposition of the resected stomach for the development of a primary carcinoma. The risk to develop a carcinoma after resection for peptic ulcer shows a two- to three-fold increase compared to gastric cancer mortality of the normal population. Because of the lack of typical symptoms for gastric stump cancer surgical treatment will occur late and the 5-years survival rate is only 1.38%. The cause of the increased cancer risk after gastric resection seems to be the atrophic gastritis in the gastric remnant which is found after a few years.
