Bowel Preparation for Colonoscopy Among Individuals With Crohn's and Ulcerative Colitis Disease.
The purpose of this study is to compare how effective and how tolerable two different bowel preparation laxatives are for colonoscopy. The aim is to compare oral sulfate solution (OSS) to another laxative called 2L polyethylene glycol (PEG) solution to see which is more effective and more tolerable by individuals with IBD (Crohn's disease or Ulcerative colitis).
