Does Inspection During Insertion Improve Adenoma Yields During Colonoscopy?

NCT01035775 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 340

Last updated 2018-11-16

No results posted yet for this study

Summary

Colonoscopy is not a perfect test. It misses a substantial number of neoplastic lesions and has some risk of missing cancer. Nearly all work on detection during colonoscopy has focused on the withdrawal phase of the examination. This randomized, controlled trial will compare the additional effect on the rate of adenoma detection of mucosal inspection during colonoscope insertion, with inspection during instrument withdrawal, in patients undergoing colonoscopy for colorectal cancer screening or surveillance.

Conditions

Interventions

PROCEDURE

Inspection during insertion

The colonic mucosa will be inspected for lesions during insertion of the instrument, and during withdrawal of the instrument.

PROCEDURE

Inspection during withdrawal

The colonic mucosa will be inspected for lesions only during withdrawal of the instrument from the cecum. The instrument will be inserted to the cecum without deliberate inspection.
