Diagnostic Yield of Advanced Colorectal Neoplasia at Colonoscopy, According to Indications: An Investigation from the Korean Association for the Study of Intestinal Diseases (KASID)

Abstract

Age, gender, and referral for colonoscopy from primary care physician constituted important independent predictors of advanced CRN in patients undergoing colonoscopy.

Disparities in prevalence, location, and shape characteristics of colorectal neoplasia between South Korean and U.S. patients

“…Previously, in one of the few controlled studies comparing Asian and Western patients, 16 Western men had a slightly higher prevalence of neoplasia than Chinese men (27.8% vs 22.2%, P Z .01), but Western women had a prevalence of neoplasia higher than that of Chinese women (14.5% vs 9.6%, respectively, P Z .003). In 3 uncontrolled studies on screening colonoscopy for asymptomatic South Koreans, 22,26,27 the prevalence of colorectal neoplasia and advanced neoplasia were 17.9% to 33.3% and 2.2% to 6.2%, respectively. In a prospective, multinational Asian study on screening colonoscopy, the overall prevalence of colorectal neoplasia and advanced neoplasia among Asians was 18.5% and 4.5%, respectively.…”

Korean Guidelines for Postpolypectomy Colonoscopy Surveillance

“…Although the incidence of CRC and its precursor, colorectal polyps, in South Korea is comparable to those in Western countries,22,23 Korea-specific practical guidelines for postpolypectomy surveillance are not currently available. Thus, there is a need for practical guidelines that reflect epidemiological characteristics of the Korean population and medical environment in Korea.…”
