Brief Summary:
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
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
Detailed Description:
Because the prevalence of proximal colon cancer and APN was higher in older patients15 a greater proportion of advanced colonic neoplasia or cancer would be missed if colonoscopy was not performed for older patients So if we develop a mixed strategy to offer sigmoidoscopy for younger patients and reserve colonoscopy for older patients we might be able to detect more APN with fewer colonoscopic procedures We aimed to determine an optimal cut-off age and choose an appropriate distal sentinel lesion for subsequent colonoscopy
