Summary

.Studies have demonstrated that the second examination of the proximal colon can significantly increase the proximal ADR.This study aimed to determine the impact of second examination of the proximal colon on AMR compared to conventional examination.Consecutive patients aged 40-75years undergoing colonoscopy for screening.Tandem withdrawal was used in the proximal colon.Patients were randomly assigned to either the second examination(SE) or the conventional examination(CE) group.The primary outcome measure was proximal AMR,defined as the number of proximal adenomas detected in the second pass（CE group）or the third pass（SE group）divided by the total number of proximal adenomas detected during the tandem colonoscopy.

Conditions

  • Adenoma Miss Rate

Interventions

DIAGNOSTIC_TEST

second examination of the proximal colon

For patients in the SE group, the colonoscope was reinserted into the cecum, additional polyps were removed from the proximal colon during the third withdrawall(third pass), and the remainder of the colon from splenic flexure to rectum was examined in a standard manner
