Abstract: ObjectiveTo find out the risk factors and the incidence of lithiasis. MethodsA questionnaire was formulated by the National Biliary Surgical Group. It was sent to the medical staff of all levels of hospitals in the Zunyi Region, Guizhou to fill in on surgically proven cases of cholelithiasis. The clinical data were collected and analyzed using SPSS 13.0. ResultFor lithiasis, the gender ratio was 1∶ 1.78; the peak age was 41-year and 51-year respectively. The proportion of cholecystolithiasis (n =4456 ; 86.76 ％) and choledocholithiasis (n =554;10.79 ％ ) was comparatively higher than in other regions in China. ConclusionsThe commonest type of lithiasis in Zunyi was cholecystolithiasis. There was an increasing tendency for lithiasis to develop in young people. Lithiasis was closely associated with factors such as gender, food and occupation.
