[Esophageal perforation in a fruitless attempt at endotracheal intubation].

Esophageal perforation is a rare but potentially serious complication of endotracheal intubation, often leading to mediastinitis. The diagnosis should be performed rapidly, based on suggestive clinical signs as well as on plain chest roentgenograms and contrast esophagogram. The usual treatment consists of broad spectrum antibiotherapy, prompt surgical closure of the perforation and adequate drainage of the area.

Intraepithelial carcinoma of the oesophagus: endoscopic morphology.

The endoscopic detection of 18 "early" hypopharyngo-oesophageal carcinomas, has allowed us to perform a detailed study of the morphological correlation between endoscopy and histology (in 10 cases). We have thus defined 4 different endoscopic types of intraepithelial carcinomas; their morphology, mapping and evolution are greatly variable. In high risk groups (heavy smoking and alcohol consumption, ENt-cancer) the multicentricity of intraepithelial carcinomas (80%) entails a thorough endoscopic screening of the upper digestive tract (mouth, pharynx, oesophagus) and of the lower respiratory tract (larynx, trachea and bronchi).
