Abstract
The Malltry-Weiss syndrome has been said to be one of the important cause of the upper gastrointestinal bleeding. We experienced 11 cases of this syndrome diagnosed by the emergency endoscopy from October 1975 to April 1981. The incidence was 9.8% of upper gastrointestinal bleeding in our series. The figure was much higher than the rate which had been thought. As the result, the emergency endoscopy was thought to be useful for the diagnosis and selection of treatment of the Mallory-Weiss syndrome. Nine cases were treated nonsurgically, and 2 cases were treated operatively.
