BACKGROUND/AIMS: To understand the epidemiologic characteristics of gallstone disease in Korea and to evaluate the chronological changes of gallstone disease, the authors performed this prospective nationwide cooperative study.
METHODS
The subjects were 1,263 patients with gallstone. They were hospitalized at 19 hospitals in Korea from February to July, 1997. The study protocals were recorded on 1,263 patients and gallstones were removed from 1,133 patients and their chemical compositions were analyzed.
RESULTS
Among total patients with gallstone, the proportions of patients with gallbladder, common bile duct (CBD) and intrahepatic duct (IHD) stones were 64.0%, 21.9%, and 14.1%, respectively. Male to female ratio was 1 versus 1.3. The gallbladder stones were categorized as cholesterol (58.1%), black pigment (25.2%) and brown pigment (12.1%) stones. The CBD stones were classified into brown pigment (76.1%), cholesterol (18.4%) and black pigment (3.5%) stones.
