BACKGROUND: Primary screening with sigmoidoscopy would miss a substantial proportion of advanced proximal neoplasia (APN), but screening with universal colonoscopy is costly. The aim of this study is to assess the efficacy of mixed strategy which uses sigmoidoscopy for younger patients and colonoscopy for older patients.
MATERIALS and METHODS: We analyzed an established database containing consecutive average-risk adults aged 50 or older who underwent screening colonoscopy as part of health check-up. We assessed the efficacy of mixed screening strategy using colonoscopy for persons aged at and above a certain cut-off age and sigmoidoscopy for persons aged below that age. Those who underwent sigmoidoscopy initially would be referred for subsequent colonoscopy if distal sentinel lesion was detected.
