Gabexate Mesylate In The Prevention Of Post-endoscopic Retrograde Cholangiopancreatography Pancreatitis: A Systematic Review And Meta-analysis Update.
Published 2008 · Medicine
BACKGROUND Acute pancreatitis is a common complication of endoscopic retrograde cholangiopancreatography (ERCP), and the benefit of pharmacologic treatment of the condition is unclear. Although prophylactic use of gabexate mesylate (GM) for the reduction of pancreatic injury after ERCP has been evaluated, uncertainty remains regarding the effectiveness of GM treatment in post-ERCP pancreatitis (PEP). OBJECTIVE The aim of this study was to determine through systematic review and meta-analysis the effectiveness and tolerability of GM in the prophylaxis of PEP. METHODS MEDLINE (January 1966-July 2007), EMBASE (January 1966- July 2007), the Cochrane Controlled Trials Register on The Cochrane Library (Issue 2, 2007), and the China Biological Medicine Database (January 1978-July 2007) were searched. We used the method recommended by The Cochrane Collaboration to perform a systematic review and meta-analysis of randomized controlled trials (RCTs) of GM in the prevention of PEP. RESULTS Of the 38 studies identified, 31 were excluded for the following reasons: they were reviews or editorials (9 articles); were meta-analyses (4); had differences in cointerventions (4); were nonrandomized controlled trials or had incorrect randomization (4); were repeat publications (2); lacked a placebo group (1); or other (7). Seven RCTs, totaling 2883 patients, conducted in a variety of languages were included in the meta-analysis. When the RCTs were analyzed, odds ratios for GM were 0.65 (95% CI, 0.36-1.18; P 0.16) for PER 1.90 (95% CI, 0.54-6.65; P 0.32) for severe PEP, 0.55 (95% CI, 0.17-1.77; P 0.32) for the case-fatality ratio of PEP, 0.88 (95% CI, 0.74-1.05; P 0.16) for post-ERCP hyperamylasemia, and 0.78 (95% CI, 0.49 1.25; P 0.30) for post-ERCP abdominal pain. No evidence of publication bias was found. CONCLUSIONS No beneficial effects of GM on acute pancreatitis, the PEP mortality rate, or post-ERCP abdominal pain or hyperamylasemia were found; therefore, GM cannot be recommended for the prophylaxis of PEP.
