[Endoscopic diagnosis of malignant tumors of the esophagus]

The results from 1389 fibroesophagoscopies in case of various esophageal diseases are reported. The diseases, in 57.6 per cent of the examined, are admitted to be precancerous. The endoscopic picture of initial carcinoma of esophagus is described and in 77 patients--of already manifested carcinoma (histologically confirmed). In 35 of the patients the lower third of esophagus was involved in the carcinoma process, in II--the middle third and in 2--the upper third. Polypoid carcinoma of esophagus was found in 55 per cent of the examined, infiltrating carcinoma--in 34 per cent and ulcerous carcinoma--in II per cent. The complex fibroendoscopic examination, combined with a biopsy and cytology, provide the highest potentialities of an accurate diagnosis of the malignant tumours of esophagus.
