Brief Summary

Colonoscopy withdrawal times are a critical element in determining quality of colonoscopy; however, few studies have evaluated specific factors that may influence the duration of withdrawal, and specifically short withdrawal times. Other factors affecting polyp detection rate, one element of quality of colonoscopy, also need further study. By collecting data on hundreds of colonoscopies performed by 9 endoscopists, our goal was to identify factors associated with withdrawal time, inappropriately short withdrawal times, and polyp detection rate during colonoscopy.
