[The place of total aerodigestive upper endoscopy in oncology].

The epidemiology of upper digestive and bronchogenic carcinoma shows a large overlap between the high risk groups. Thus, a candidate for bronchogenic carcinoma is also a possible candidate for upper digestive cancer. Furthermore, the high frequency of multiple carcinoma in the upper aero-digestive tract, the esophagus and the tracheo-bronchial tree warrants a pan-endoscopic (buccal-pharyngo-esophagoscopy and laryngo-tracheo-bronchoscopy) approach to the problem. Using this type of endoscopy, 16 multiple carcinomas have so far been simultaneously discovered among 200 pan-endoscopies.
