Laparoscopic cholecystectomy in Leicester: an audit of 555 patients

Laparoscopic techniques have revolutionised the surgical approach to cholecystectomy, even though there have been no published randomised controlled trials to demonstrate the safety of this approach. We present an audit of 555 patients offered laparoscopic cholecystectomy. In all, 54 patients (9.7%) were converted to an open procedure. Peroperative cholangiography (POC) was attempted in 190 cases (34.2%) and achieved in 141 (25.4%). Major complications occurred in 26 cases (4.7%) including 5 (0.9%) deaths, two of whom had major pre-existing morbidity. There was one common bile duct (CBD) injury (0.18%). There were 30 patients (5.4%) found to have CBD stones, 27 of which were cleared at ERCP, and three converted to open exploration. Cholecystectomy by any route is a major operation and we conclude that careful case selection remains imperative. However, morbidity is favourable compared with open cholecystectomy, and comparable with other reports using the laparoscopic technique. Our experience of CBD injury (0.18%) is also acceptable compared with the risk of injury during open cholecystectomy. There were 312 patients (56.2%) who did not undergo perioperative CBD imaging with ERCP or POC and three of these developed early symptomatic retained stones. This group requires further follow-up.
