[Clinico-endoscopic problems in malignant changes of the gastric stump].

The authors give a report on occasional difficulties concerning the radiological and endoscopic clarification of the malignant changes at the gastric stump after treatment of resection. Four relevant cases are stated and explained. The endoscopy (glass fibre gastroscopy) together with the biopsy is at present the most reliable method for the diagnosis of the pathological processes in the remaining part of the stomach. A regular endoscopic and radiological control of patients with gastric resection is desirable.
