Feasibility and Effectiveness of Colonic Irrigation

The primary endpoints for this study are: * Overall quality of bowel cleansing for each of the three segments of the colon (ascending, transverse, and descending) as measured by the Boston Bowel Preparation Score (BBPS), a validated numerical scale for bowel cleanse (0-3 for each colon segment; 0-9 total score) (6). * Patient satisfaction, as measured by a questionnaire administered by a study investigator via follow-up phone call after completion of the colonic irrigation and subsequent colonoscopy.
