Background: Incidentally discovered gallbladder polyp in health check-up has been increasing in numbers due to extended use of ultrasonography. Past researches have reported on the relationship between body mass index and gallbladder (GB) polyp. As there has been a recent rise in the prevalence of obesity, this research attempted to study GB polyp prevalence and the trend according to time elapse in Korea.
Methods: Retrospective cross sectional research was carried out with the data of Korean Association of Health Promotion, between 2nd. Jauary. 2003 to 3rd. Aug. 2007, for subjects who received abdominal ultrasonography. Those excluded were,below 20 years of age, non-asian and who have received cholecystectomy. The number of eligible subjects were 137,135, where 69,493 were male and 67,642 were female.
Results: Out of 137,135 subjects, the number of subjects with GB polyp were 5,278, where 3,163 were male and 2,115 were female. According to 2005 census, the age adjusted prevalence was 3.7% (3,656 per 100,000). The prevalence for men was 4,403 per 100,000 (4.4%) and for women 2,943 per 100,000 (2.9%). The prevalence has been increasing for the past five years.
Conclusion: The prevalence of GB polyp in Korea is found to be higher than the pre-existing reports and the prevalence is higher in male than female. The prevalence is on the increase and there is a need to be more attentive to the issue in the future.
