Role of the teaching hospital in the development of a laparoscopic cholecystectomy program.

: Laparoscopic cholecystectomy was introduced at McGill University-affiliated hospitals in a planned manner to evaluate the safety and results of this new procedure while training attending and resident surgeons. Laparoscopy was performed with the intent of carrying out cholecystectomy in 500 consecutive patients (70% female, 30% male), whose age averaged 48 years (range from 7 to 93 years). Thirty-seven percent had undergone intra-abdominal surgery previously, and 9.1% had had acute cholecystitis. There were two common-bile-duct injuries and one major small-bowel injury. The procedure had to be converted to open cholecystectomy in 25 (5%) patients. There were no deaths. The mean duration of surgery was 88 minutes. Fifty-five percent of patients were discharged home in 24 hours or less after surgery, and 75% were back to normal activity within 1 week of discharge. Fourteen attending staff and 8 senior residents achieved competence to carry out laparoscopic cholecystectomy independently.
