To determine the efficacy of somatostatin or octreotide for the treatment of acute nonvariceal upper gastrointestinal hemorrhage.
Database searches of English-language articles published between 1966 and 1996 and the bibliographies of all related articles and textbook chapters.
Randomized clinical trials comparing somatostatin or octreotide with H2 blockers or placebo in patients with a clinical or endoscopic diagnosis of acute nonvariceal upper gastrointestinal hemorrhage.
Methods and quality of the studies were evaluated, and quantitative data on outcomes, including continued bleeding, rebleeding during the treatment period, need for surgery, and transfusion requirement, were extracted.
Among 1829 patients from 14 trials, the relative risk (RR) for continued bleeding or rebleeding was 0.53 (95% CI, 0.43 to 0.63) in favor of somatostatin, with a number needed to treat (NNT) of 5. Among 7 investigator-blinded trials, the relative risk was 0.73 (CI, 0.64 to 0.81) and the NNT was 11. Somatostatin was efficacious for peptic ulcer bleeding (RR, 0.48 [CI, 0.39 to 0.59]; NNT, 4) and showed a trend toward efficacy for non-peptic ulcer bleeding (RR, 0.62 [CI, 0.39 to 1.002]). Although the overall results suggested a decreased need for surgery in the somatostatin group, a subgroup analysis of investigator-blinded trials revealed a more modest effect that was not statistically significant (RR, 0.94 [CI, 0.87 to 1.001]).
Somatostatin may reduce the risk for continued bleeding from acutely bleeding peptic ulcer disease. Somatostatin may be useful either as an adjunct treatment before endoscopy or when endoscopy is unsuccessful, contraindicated, or unavailable.
