title: Epidemiology of gallbladder polyps: an ultrasonographic study of male self-defense officials in Japan.
abstract: The prevalence and risk factors of gallbladder polyps diagnosed by ultrasonography were investigated in 2739 male self-defense officials who received a retirement health examination at the Self-Defense Forces Fukuoka Hospital, Japan, between October 1986 and December 1990. Excluding 38 men whose gallbladder had been removed previously, 143 men were found to have gallbladder polyps. The overall prevalence of gallbladder polyps was 5.3%. The relation between gallbladder polyps and smoking, alcohol use, body mass index, glucose tolerance, and serum lipids was examined in 137 men with stoneless polyps and 2495 normal subjects. Whereas smoking tended to be inversely associated with gallbladder polyps, none of the other lifestyle and clinical variables were related to this condition. Thus the reported risk factors of gallstones had no relation to gallbladder polyps.
