ABSTRACT
Objective To analyze the clinical features of patients with cholelithiasis treated in our hospital in the recent 10 years to explore the changing tendency of the spectrum of cholelithiasis in the Jiaodong region. Methods The clinical data of 2899 patients receiving operation for cholelithiasis in this hospital between January 1998 and January 2008 were retrospectively analyzed. The clinical parameters of sex, age and the lesion sites were reviewed. Compared with the clinical data of cholelithiasis patients in 1991, the data of the 2899 patients were statistically analyzed by SPSS 12.0 package.Results Significant differences existed in sex, e peak morbidity, and lesion sites. The ratio of male patients and female patients with cholelithiasis in differents site had obvious diversity. The constituent ratio of the female was manifestly higher than that of the male. The peak morbidity age range of cholecystolithiasis was 40 to 69. The peak age of gallbladder stones combined with common bile duct stones was 70 to 79, which was the same as that of common bile duct stones. The peak age of intrahepatic bile duct stones was 40 to 59. The constituent ratio of cholecystolithiasis was obviously higher than cholelithiasis in other sites. The incidence of cholecystolithiasis increased with age. Conclusion In the recent 10 years, female's ratio of gallbladder stones and intrahepatic stones was higher than male's.The morbidity of cholelithiasis significantly increased in aged patients. The spectrum of cholelithiasis has changed significantly.
