Study Details

Study Description

Brief Summary

High quality bowel cleaning preparation was most important prerequisites of a accurate colonoscopy, because even a small amount of residual fecal matter can obscure small polyps and increase unnecessary procedure time. Until now, several studies evaluated the impact of bowel preparation on the quality of colonoscopy using comparison of the polyp detection rate in patients with adequate bowel preparation status to that in patients with inadequate bowel preparation status during colonoscopy. However, there was no direct measurement the effect bowel preparation status on the polyp missing rate, the quality of colonoscopy, using tandem colonoscopic evaluation in prospective setting.

Condition or Disease Intervention/Treatment Phase

    Detailed Description

    1. Study flow

    2. All patients perform Colonoscopy

    • record the polyp size, shape, location and number

    • record the factors affecting polyp missing rate

    • Patients' age / gender

    • Indication of colonoscopy

    • colonoscopist career

    • colonoscopy withdrawal time

    • bowel preparation status according to scale of U.S. Multi-Society Task Force on colorectal cancer, Aronchick's scale and Ottawa bowel preparation quality scale

    1. the patients needed or wanted to 2nd stage colonoscopic polypectomy (2nd stage polypectomy was performed within 6 month)
    • record additionally detected polyp - size, shape, location and number
