title: [Effects of anesthesia on the lower sphincter of the esophagus].
abstract: The lower oesophageal sphincter (LOS) is the most important structure preventing regurgitation of gastric contents, with the risk of tracheobronchial aspiration, as it occurs in cases of laryngeal incompetence in connection with general anaesthesia. This article reviews anatomical data, means of assessment of the sphincter function, as well as the effects of anaesthetic agents and situations carrying a high risk of regurgitation and tracheobronchial aspiration.
