title: Prospective study of laparoscopic cholecystectomy in two hundred and fifty patients.
abstract: Two hundred and fifty consecutive patients (151 women, 99 men, age 49.3 years) with symptomatic gallstones as diagnosed on ultrasonography underwent elective laparoscopic cholecystectomy over a 12-month period. Preoperative intravenous cholangiography (IVC) and endoscopic retrograde cholangiography (ERC) were also performed in 203 and 200 patients, respectively. Laparoscopic cholecystectomy was successfully performed on 248 of the 250 patients (99.2%). Two patients required conversion to open cholecystectomy because of a pin hole injury to the portal vein in one case, and because of technical difficulties with the dissection due to severe adhesions in the other patient. Procedure time in the initial 100 cases decreased from an average of 216 minutes for the first ten cases to 87 minutes for the last 30 cases, including the time required for intraoperative cholangiography (IOC). Bile duct stones were found in 4 cases on IOC which were diagnosed by preoperative ultrasonography, IVC and ERC in 0, 2 and 3 cases respectively. An intraabdominal drain was inserted for two days in all cases. The mean hospital stay was 8.6 days (range 4 to 19 days) with no readmissions. No complications were seen at short-term follow-up one month after discharge. Although there was a significant learning period, the procedure was safe and effective and could be performed with minimal risk. The results show that physicians with experience in both endoscopy and laparoscopy are well qualified to perform laparoscopic cholecystectomy after appropriate training.
