Abstract:
The usefulness of antibiotic prophylaxis in biliary surgery is well established. When antibiotic prophylaxis is not used, wound infection rates after biliary surgery range from 10% to 25%. With antibiotic prophylaxis, the rates can be reduced to less than 5%. Three questions are still controversial: Do all patients undergoing biliary surgery require antibiotic prophylaxis? What is the ideal antibiotic for use in biliary surgery? What should be the duration of antibiotic prophylaxis? In this study we prospectively evaluated the efficacy of a single dose of antibiotic prophylaxis in biliary surgery, administered to patients at high risk for infection, in a trial comparing cefonicid (a cephalosporin with a long half-life) with mezlocillin (a broad-spectrum ureidopenicillin).
