| 4 | Antibiotic prophylaxis to prevent complications in endoscopic retrograde cholangiopancreatography:A systematic review and meta-analysis of randomized controlled trials显示文摘BACKGROUND The prophylactic use of antibiotics in endoscopic retrograde cholangiopancreatography(ERCP)is still controversial.AIM To assess whether antibiotic prophylaxis reduces the rates of complications in patients undergoing elective ERCP.METHODS This systematic review and meta-analysis were performed following the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines.A comprehensive search of multiple electronic databases was performed.Only randomized controlled trials were included.The outcomes analyzed included bacteremia,cholangitis,sepsis,pancreatitis,and mortality.The risk of bias was assessed by the Cochrane revised Risk-of-Bias tool for randomized controlled trials.The quality of evidence was assessed by the Grading of Recommendation Assessment,Development,and Evaluation.Meta-analysis was performed using the Review Manager 5.4 software.RESULTS Ten randomized controlled trials with a total of 1757 patients that compared the use of antibiotic and non-antibiotic prophylaxis in patients undergoing elective ERCP were included.There was no significant difference between groups regarding incidence of cholangitis after ERCP[risk difference(RD)=-0.02,95%confidence interval(CI):-0.05,0.02,P=0.32,cholangitis in patients with suspected biliary obstruction(RD=0.02,95%CI:-0.08 to 0.13,P=0.66),cholangitis on intravenous antibiotic prophylaxis(RD=-0.02,95%CI:-0.05 to 0.01,P=0.25),septicemia(RD=-0.02,95%CI:-0.06 to 0.01,P=0.25),pancreatitis(RD=-0.02,95%CI:-0.06 to 0.01,P=0.19),and allcause mortality(RD=0.00,95%CI:-0.01 to 0.01,P=0.71).However,the antibiotic prophylaxis group presented a 7%risk reduction in the incidence of bacteremia(RD=-0.07,95%CI:-0.14 to-0.01,P=0.03).CONCLUSION The prophylactic use of antibiotics in patients undergoing elective ERCP reduces the risk of bacteremia but does not appear to have an impact on the rates of cholangitis,septicemia,pancreatitis,and mortality. | Maria Fernanda Shinin Merchan Diogo Turiani Hourneaux de Moura Guilherme Henrique Peixoto de Oliveira Igor Mendonça Proença Epifanio Silvino do Monte Junior Edson Ide Caroline Moll Sergio A Sánchez-Luna Wanderley Marques Bernardo Eduardo Guimarães Hourneaux de Moura | 2022 | World Journal of Gastrointestinal Endoscopy2022，14，11： | 1 |
