  • Title: Etiology and prevalence of severe persistent upper gastrointestinal bleeding.
    Author: Fleischer D.
    Journal: Gastroenterology; 1983 Mar; 84(3):538-43. PubMed ID: 6600435.
    Abstract:
    A prospective study was undertaken to establish the etiology and prevalence of episodes of upper gastrointestinal bleeding which are severe and persistent. During a 12-mo study period, 175 patients had one or more episodes of upper gastrointestinal bleeding. Thirty-six (20.6%) of the 175 patients had bleeding that was classified as severe and persistent. Upper gastrointestinal bleeding that occurred more than 24 h after admission was more apt to persist than bleeding that was a presenting complaint (32.4% vs. 12.8%, p less than 0.001). Bleeding due to esophageal varices was the single most common cause. Although the majority of upper gastrointestinal bleeding episodes are self-limited, about one-fifth are not. Studies to evaluate the many new therapeutic modalities for upper gastrointestinal bleeding should attempt to exclude patients whose bleeding will abate spontaneously.
