Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This was a randomized, endoscopists' blinded comparison of bowel colonoscopy cleansing and tolerability of a prespecified low-residue diet compared with a clear liquid diet and Polyethylene Glycol bowel preparation. Outcome measures included efficacy of bowel preparation, patient preparation tolerability and side-effects.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

An adequate examination is dependent on the bowel colonoscopy cleansing of stool. There are many different colon preparations, however endoscopists traditionally recommend the patient remain on a clear liquid diet for at least 24 h prior to their colonoscopy to reduce continued residue inflow into the colon from the small bowel, in addition the large volume preparation with PEG. The most common problems leading to less than adequate colon cleansing include lack of compliance with the clear liquid diet and difficulty taking the large volume preparation.
