N/A Background : Gallbladder (GB) polyps are now increasingly detected by ultrasonography. We investigated the prevalence and risk factors of GB polyps in health screening population. Methods : An ultrasonographic study of GB polyps were conducted in 35,012 subjects who received a paid health screening examination at Samsung Medical Center. Controls, twice the subjects with GB polyp, were randomly selected from the cases with normal GB. The demographic characteristics and biochemical parameters were recorded. Results : The overall prevalence of GB polyps was 2.94% (1,330/15,573). Among them, 3.63% were men, 2.09% were women. In both males and females, the prevalence was highest in their 40s. The diameter of GB polyps ranged from 2 mm to 20 mm (mean 4.5 mm). Most polyps (98.3%) were less than 10 mm in diameter. Of 1,030 subjects, 64% had a single polyp and 36% had multiple polyps. Multiple logistic regression, with reference group of body mass index (BMI, <22.5 kg/m2), showed odds ratio of 1.074 and 1.864 for BMI groups of 22.5-24.9 and 25 or more respectively. In contrast, other demographic characteristics and biochemical parameters, such as age, smoking, alcohol use, glucose, liver function tests, lipid profiles and HBsAg carriage were lack of any relation to GB polyps. Conclusions : GB polyps are not likely to be rare in Korean adults despite their low prevalence compared to other reports. The body mass index may be a risk factor for GB polyps.

Granular cell tumor is rare and is thought to originate from neurogenic cells. The tumor rarely occurs in the colon and its occurrence in the appendix is extremely rare. We report a case of granular cell tumor developed in the appendix for the first time in Korea. The tumor was discovered incidentally during colonoscopy and removed by using an endoscopic polypectomy. The expression of S-100 protein and lack of desmin represent that the tumor is relatd with Schwann cell originally. (Kor J Gastroenterol 2000;36:404 - 407)
