Increased cholecystectomy rate after the introduction of laparoscopic cholecystectomy in Scotland.

This survey determined the effect of the introduction of laparoscopic cholecystectomy on the rates of cholecystectomy (total and laparoscopic) in Scotland. From 1977 to 1990, the Scottish cholecystectomy rate fell by an average of almost 1% per annum. With the advent of laparoscopic cholecystectomy, the total cholecystectomy rate (open and laparoscopic) rose considerably--by 18.7% from 1989-93 (p < 0.05). The largest increase (25%) was observed in the 45-64 years age group but it was also particularly evident (19%) in elderly patients (65-74 years). Subjects were more likely to undergo laparoscopic cholecystectomy than open cholecystectomy if they were young and female. The increased cholecystectomy rate observed merits careful scrutiny and health economic evaluation.
