A prospective study of 276 patients admitted and operated on with the diagnosis of cholelithiasis was conducted from December, 1991, to November, 1997. These patients were operated on by our basic working group and most of them were referred by family physicians graduated in our Faculty. Gallstones were classified into pigment gallstones and cholesterol gallstones according to their macroscopic characteristics on cutting. A survey was done with the possible risk factors. Cholesterol gallstones (76.1 %) predominated over the pigment ones. The females prevailed over males in relation of 4:1. The diagnosis of cholelithiasis was determined more frequently in the fourth and fifth decades of life. Pigment gallstones were commonly observed at more advanced ages. Obesity (39.5 %), diabetes mellitus (19.5 %) and parity (31.8 %) were the main risk factors. Therefore, the lithiasis history in first-line relatives as well as the ingestion of oral contraceptives should be taken into account. Pigment gallstones predominated in the hemolytic states. It was proved the relationship existing between hyperlipoproteinemias of fractions IIb and IV and cholelithiasis. Only 34.5 % of the biocultures had bacterial growth. Escherichia coli and streptoccocus were the most isolated
