The prevalence of cholelithiasis has been established in population-based surveys employing ultrasonography, and major risk factors have been identified. However, the clinical and epidemiological features that distinguish patients with pigment stones from those with cholesterol stones have received little attention. We respectively surveyed 150 patients undergoing cholecystectomy for gallstone disease at State University Hospital of Ulaanbaater. Clinical and epidemiological data were collected during patients interviews and by chart review. Gallstones were collected at surgery, physical measurements were recorded, and stone composition was determined by visual inspection and X-ray diffractometry. Patients with pigment stones were older than patients with cholesterol stones (p<0.01). Almost all patients under age 50 years old had cholesterol stones, but most patient over 61 had pigment stones. Patients with pigment cholilethiasis had stones that were generally smaller in diameter and fewer in number than those with cholesterol stones.
