West African Journal of Medicine

|October 1, 1994

Summary

Cholecystectomy rates significantly increased from 1980-1991, especially in the last two years. This rise in gallbladder removal surgery reflects increased gallstone disease incidence and improved diagnostic methods like ultrasonography.

Area of Science:

Gastroenterology
Surgical Epidemiology

Background:

Biliary tract disease historically occupied a small percentage of general surgical beds (0.4% in 1966-68).
Gallstone disease management has seen a notable shift in resource allocation within surgical services.

Purpose of the Study:

To analyze trends in cholecystectomy procedures over a 12-year period (1980-1991).
To assess the impact of changing disease incidence and diagnostic capabilities on surgical bed occupancy for cholecystectomy.

Main Methods:

Retrospective analysis of cholecystectomy procedures performed between 1980 and 1991.
Comparison of surgical bed occupancy rates for biliary tract disease and cholecystectomy over different time periods.

Main Results:

A total of 165 cholecystectomies were performed from 1980-1991.
A significant increase in cholecystectomies was observed, with 98 procedures in 1990-1991 compared to 67 in the preceding 10 years.
Patients undergoing cholecystectomy occupied 1.5% of general surgical beds, a substantial rise from the 0.4% observed for biliary tract disease in 1966-68.

Conclusions:

The incidence of gallstone disease has genuinely increased.
Advancements in diagnostic tools, particularly ultrasonography, have contributed to earlier and more frequent diagnoses.
The rising number of cholecystectomies reflects both increased disease prevalence and improved diagnostic accuracy.
