Treatment with proton pump inhibitors in acute non-variceal upper gastrointestinal bleeding: a meta-analysis
Abstract
Medical therapy is an attractive adjuvant to endoscopic treatment in upper gastrointestinal (UGI) bleeding. This review aims to assess the treatment effects of proton pump inhibitor (PPI) therapy in acute non-variceal UGI bleeding. Outcome measures evaluated were further bleeding, surgery, all-cause deaths, ulcer deaths and non-ulcer deaths. We searched MEDLINE (1966-2002) and EMBASE (1974-2002) using the terms 'gastrointestinal hemorrhage', 'peptic ulcer hemorrhage', 'proton pump inhibitor', 'omeprazole', 'pantoprazole', 'lansoprazole', 'rabeprazole' and 'esomeprazole'. The search was extended to the Cochrane controlled trials registry database, published abstracts from five international gastroenterology conferences, manufacturers of PPI, known contacts and bibliographies from each full-length published report. We included trials published in English and non-English languages. Eligible studies were randomized controlled trials that compared the treatment effects of PPI therapy with placebo or H2 receptor antagonists in patients with acute non-variceal UGI bleeding. Of the 175 articles screened, 26 controlled trials including 4670 subjects (2317 in treatment arm and 2353 in control arm) were analyzed. The methodology, population, intervention, and outcomes of each selected trial were evaluated using duplicate independent review. Disagreements were resolved by consensus. PPI therapy significantly reduced rates of further bleeding (odds ratio [OR], 0.48; 95% confidence…
