Prospective, randomized study comparing amoxycillin-clavulanic acid and cefamandole for the prevention of wound infection in high-risk patients undergoing elective biliary surgery.

The efficacy of amoxycillin-clavulanic acid for prevention of postoperative wound infection was compared with that of cefamandole in 150 patients at risk for infected bile while undergoing elective biliary surgery in a prospective, randomized study. The two groups were comparable for age, sex, risk factors, operative procedures and positive bile cultures. Similar numbers of patients had an uncomplicated postoperative course (amoxycillin-clavulanic acid 70%; cefamandole 73%). Four patients in each group developed wound infection. The incidence of postoperative pneumonia, urinary tract infection and number of days (+/- SD) in hospital (amoxycillin-clavulanic acid 10.1 +/- 4.7; cefamandole 9.7 +/- 5.6) were similar. The efficacy of amoxycillin-clavulanic acid and cefamandole in preventing wound sepsis in high-risk patients undergoing biliary surgery was similar. Economic considerations may favour the use of amoxycillin-clavulanic acid.
