Study Population

Scheduled colonoscopy list will be reviewed to identify potential subjects for recruitment. A cover letter will be sent to the potential study subject with tablet preparation as an alternative to Golytely preparation ( PEG). For subjects who are willing to participate, a prescription for 28 tablet sodium phosphate bowel preparation as outlined in appendix: A will be mailed. A questionnaire will be given to the patients prior to their colonoscopy to identify their preferences regarding bowel preparation and their acceptance ( see appendix: B).

A separate validated questionnaire will be given to participating physicians after the procedure, to quantitate the colonic cleansing (appendix : C). Adverse events will be documented. A statistical analysis of the results will be done at the end of the study.
