In the once-a-year mass screening survey at Naru city since 1971, an analysis of the data from 1985 to 1991 especially for biliary diseases has been conducted. The total number of the subjects receiving the mass screening was 5,210 with an average of 744 yearly in the period. Twenty-seven subjects were detected having a cancer; inculding 13 cases of gastric cancer,4 of breast cancer, and 4 of colorectal cancer. Ultrasonographic examination of the biliary tract detected 40 cases of cholecystolithiasis,27 of cholesterol polyp and 14 of intrahepaticlithiasis and others. No biliary carcinoma was detected, however, five patients died of biliary carcinoma during the same period. In the meantime, disease-bearing people who need some medical treatment have been significantly decreasing during the same period compared to those in the initial period immediately after the screeing started. It can be thought that the screening greatly contributed to the decreasing, but also considered that poses a new problem. That is, when the mass screening is conducted in the same area for a long period, appropriate strategy for people who do not receive the screening and establishment of some cost-effective system would be necessary.
