Abstract
Bile bacteriology, wound sepsis and the effect of prophylactic antibiotics have been studied in a controlled prospective double blind randomized trial on 375 patients undergoing elective cholecystectomy at a district general hospital. We have examined the overall prevalence of bacteria in bile and have identified several factors associated with an increased incidence. The identity of organisms isolated from a total of 21 patients with infected wound swabs was compared with isolates from the bile at operation, and in only two instances was there a correlation. Cephazolin, given either pre-operatively, or into the wound, reduced wound infection rates compared with a control group (from 11·8 to 2·4 per cent, P < 0.005). We conclude that the majority of wound infections in this series were caused by organisms from the patients' skin or exogenous sources, rather than by bacteria from the biliary system.
