Mallory-Weiss syndrome. Evolution of diagnostic and therapeutic patterns over two decades

During a 19-year period ending December 1978, we treated 40 patients with upper gastrointestinal bleeding secondary to the Mallory-Weiss syndrome. Thirty patients had the triad of vomiting, hematemesis and alcoholism. The presence of lacerations within the gastric cardia was associated with the presence of hiatal hernia (p = 0.03). Endoscopic examinations demonstrated 32 of 38 additional upper gastrointestinal lesions associated with the syndrome that could have been mistaken as the actual source of hemorrhage. During the second decade, as compared with the first decade, widespread use of fiberoptic esophagogastroscopy led to the identification of the bleeding lacerations in 71% of the patients (versus 47% in the first decade) and in 80% (versus 0% in the first decade) of the patients who required an operation to control the bleeding. Although there was a 7.5% mortality rate in the two decades, the incidence of operative treatment tended to decrease (42-24%; p = 0.13). More impressive were the decreases in transfusions (14 units to 5 units per patient) and in delays before surgery (38 hours to 17 hours) (p equal to 0.05). Improved endoscopic diagnosis facilitates prompt and economic treatment.
