We investigated the prevalence of gallstones after gastrectomy by abdominal ultrasonography in 289 gastrectomized patients selected from 51, 621 Automated Multiphasic Health Testing and Services (AMHTS) examinees after barium meal studies. The results were compared with those of another group of 3, 193 AMHTS patients who routinely underwent ultrasonography (control). Among the gastrectomized patients, the overall prevalence of gallstones was 16.6%, and in the control group, 4.7%, showing a statistically significant difference (p<0.001). The prevalence of gallstones increased with age in both the control and gastrectomized groups, but was greater in gastrectomized subjects in each (10-yr) age group. The characteristics of the gallstones were compared between gastrectomized patients and the control group according to the ultrasonographic classification proposed by Tsuchiya (Yazawa et al, Jpn J Gastroenterol 85: 708, 1988). In the control group, the percentages of types I, II, III and small stone of Tsuchiya's classification were 30.2, 14.5, 21.9 and 34.3, respectively. On the other hand, in the gastrectomized group, the percentages were 8.3, 6.3, 16.7 and 68.8, respectively. This difference was statistically significant (p<0.001). The differences in the prevalence of gallstones between groups with Billroth I and II anastomoses, and between diseases necessitating gastrectomy, were not statistically significant.
