Laparoscopic cholecystectomy: an analysis on 114,005 cases of United States series.

Abstract

114,005 cases from 40 United States series of laparoscopic cholecystectomies (LC) were reviewed. Indications, conversion rates, rates of intra-operative cholangiography (IOC), and incidence of bile duct stone and iatrogenic bile duct injuries were assessed. Indications included acute cholecystitis in 11.6% and gallstone pancreatitis in 2.1% of reported cases. Conversion rate was to be primarily related to inflammation. Unsuspected bile duct stones were detected intra-operatively in 7.8% of cases. 561 major bile duct injuries (BDI) and 401 bile leaks (BL) were recorded and acute or chronic inflammation was their most important potential predisposing factor. In series with a high rate of IOC performed during LC, BDJ and BL were slightly lower and lesions recognized intra-operatively were much higher than in series with low rate of IOC. BDJ occurred in the first 50 patients of the surgeon's experience in about 91% of the cases.
