Clinical Trial Summary

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.


Description:

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.

Secondary Proportion of patient requiring repeat colonoscopy Proportion of incomplete colonoscopy due to inadequate bowel preparation Patient will be attended by physicians and blood taking will be arranged Up to 24 weeks
Secondary Incidence of treatment related adverse events Patient will be monitored after colonoscopy for any complications Up to 24 weeks
