Adenoma miss rates associated with a 3-minute versus 6-minute colonoscopy withdrawal time: a prospective, randomized trial

摘要

Background and Aims: The 6-minute withdrawal time for colonoscopy, widely considered the standard of care, is controversial. The skill and technique of endoscopists may be as important as, or more important than, withdrawal time for adenoma detection. It is unclear whether a shorter withdrawal time with good technique yields an acceptable lesion detection rate. Our objective was to evaluate a 3-minute versus a 6-minute withdrawal time by using segmental tandem colonoscopy.
