T k e results of a study o f the value of fibreoptic endoscopy in the assessment of 76 patienfs with malignant infiltration of the stomach are presented. The Olympus gastroscope (model GTF-A), the LoPresti axophagoscope and the Olympus a?sophagoscope (model EF) were used. O f 76 patients with a radiological diagnosis of gastric cancer, 61 were submitted to endoscopy. Endoscopy was contraindicated in 15 patients for a variety of reasons. In 61 patients it was attempted, but in five the procedure failed. O f the 56 patients who had successful endoscopy, a dingnostic accuracy o f gastric cancer was achieved in 87.5%.
Fibreoptic czsophagoscopes are superior to fibreoptic gastroscopes in the diagnosis of cancer of the upper regions of the stomach. Errors in endoscopic interpretation occurred with ulcerating cancers of the lesser curve area of the stomach, and with cancer of the distal antrum.
