[Results of combined radiological and endoscopic investigation of the stomach (author's transl)].

In 817 patients who were subjected both to X-ray examination and endoscopy of the stomach, the diagnosis was verified histologically. The radiological findings were confirmed in 86% of the cases and the results of endoscopy were verified in 89% of cases. The diagnosis of gastric ulcer was confirmed by X-rays in 87% of cases, by endoscopy in 95%. 88% of the malignant tumours of the stomach were discovered on X-ray examination and 89% through endoscopy. The diagnostic results of X-ray examination to detect carcinoma of the gastric stump or of an anastomosis were somewhat poorer. With optimal technique the results of radiodiagnostic examination are hardly inferior to those of endoscopy. There are advantages and disadvantages inherent in both techniques but they are of a different nature so that the two methods are by no means competitive; indeed, they are complementary and a combination of both methods yields maximum results. X-ray examination offers considerable advantages if it is carried out before endoscopy.
