[Endoscopic diagnosis of tumors of the esophagus]

The analysis of the data reported indicates that fibroesophagoscopy is a valuable adjunct in the diagnosis of esophageal cancer, which may be used both under stationary and outpatient conditions. The latter is of special importance for prophylactic examinations of high-risk group individuals. The possibility to establish histological and cytologic diagnosis by means of this method of investigation is essential for tactical aspects of the treatment in such patients. The use of roentgenological and endoscopic methods of study allows a more precise judgement to be formed as to the character of esophageal involvement.
