RESUMO
To carry out a meta-analysis of published studies in order to evaluate the clinical efficacy of prophylactic antibiotics in severe acute pancreatitis [SAP]. MEDLINE, China Biological Medicine, Embase and Cochrane Data Base for Systematic Reviews were searched for randomized controlled trials on the efficacy of prophylactic antibiotics in patients with SAP from 1966 to 2004. Six studies met our inclusion criteria. Two authors [G.S.X. and Z.H.W.] independently extracted the following data from these studies: trial design, characteristics of participants and outcomes. Data were analyzed by Revman 4.2 software. In patients with SAP, prophylactic antibiotics, including broad-spectrum antibiotics that usually achieve therapeutic pancreatic tissue levels, did not reduce pancreatic infection [relative risk, RR, 0.77, 95% confidence interval 0.48-1.24, p = 0.28], surgical intervention [RR 0.84, 95% confidence interval 0.40-1.74, p = 0.64] and mortality rate [RR 0.54, 95% confidence interval 0.28-1.04, p = 0.07]. Prophylactic antibiotic administration is not an appropriate treatment strategy in patients with SAP, it should be limited in patients with pancreatic necrosis, as demonstrated by computerized tomography
