Official title
The Utility of Time Segmental Withdrawal During Screening Colonoscopy for Increasing Adenoma Detection Rate. A Randomized Controlled Clinical Trial.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Colonoscopy( examining the colon with a flexible tube and a camera ) is usually done for screening purposes to find any precancerous lesions (polyps) at an early stage. During the colonoscopy the doctor will advance the colonoscope to the end of your colon and start examining the colon for any polyps. "Withdrawal time" is the period of time the doctor spends examining the colon. Doctors usually spend six minutes examining the colon after they reach the end of the colon. Studies have showed that spending more withdrawal time detects more lesions. The proposal to dedicating half of the withdrawal time during colonoscopy in examining the right side will increase the detection of polyps in the right side of the colon. There will be no other changes in the procedural aspect of the colonoscopy.
