Single Dose Versus Split Dose Polyethylene Glycol-based Colonic Lavage for Colonoscopy

Proper bowel cleansing prior is an essential requirement for the conduct of colonoscopy. However, due to the nature of cleansing process, the ideal bowel cleansing preparation remains elusive. The objective of this study is to compare the efficacy, safety and tolerability of oral polyethylene glycol lavage given either as a single dose or split dose. The study will be a randomized controlled single blind two group study. The primary study outcomes will be the previously validated Ottawa bowel preparation score.
