title: [Routine endoscopy of the esophagus in buccal, pharyngeal and laryngeal cancers].
abstract: We practiced a systematic endoscopy of the upper part of the aero-digestive tract on 160 patients suffering from a cancer in the mouth, the pharynx and the upper part of the larynx. This unit, going from the mouth to the cardia does really exist: it has the same epithelial coating, the same function and is liable to suffer the same damages. It is the seat of many well-known cancerous localizations that always need to be searched for on principle when face to face with any cancer. The endoscopic examination so conceived allowed the authors to find a cancerous association on the very level of the upper sero-digestive tract among 14 per cent of the patients; 4 out of these 14 per cent having oesophageal damages impossible to detect clinically on one hand, and often radiologically on the other hand. Morever, 3 out of 7 of lesions were tiny: from 1 to 3 millimetres, extending the limits of the diagnosis of the cancer of the aesophagus and perhaps leaving better therapeutic possibilities.
