Colonoscopy Clinical Trial
Official title:
Efficacy, Tolerance and Safety of Split Dose Bowel Preparation for Colonoscopy: 4L Polyethylene Glycol (PEG) Versus 1L Polyethylene Glycol Plus Sodium Picosulfate-magnesium Citrate (SPMC)
4L split dose PEG is the gold standard for bowel preparation, however it comes with poor tolerability and poor compliance. Combination of PEG with different agent is useful in reducing total volume, improving compliance and tolerance of patient. The objective of this study is to demonstrate that combination bowel preparation, PEG plus SPMC solution, has similar efficacy and safety profile whereas with a better tolerance when compared to large volume PEG.
This is a prospective, randomized, single-center, single-blinded, non-inferiority trial. Participants with out patient colonoscopy arranged will be included and randomized in a 1:1 ratio to receive either a split dose of 4L PEG + Electrolyte (Klean-prep® ) or 1L Klean-prep® plus 2 sachets SPMC (Picoprep®). Trained endoscopists will be using the Boston Bowel Preparation Scale (BBPS) to assess the quality of bowel preparation. Patient would also rate the tolerance, compliance and adverse effect by filling the questionnaire before the colonoscopy. ;
