This is a prospective randomized study which will be done at main campus Cleveland Clinic. The investigators will be comparing the colon cleansing by the Boston Bowel Preparation Scale in participants undergoing colonoscopy as an inpatient at our hospital. Participants will be randomized to the the standard of care (4 Liter polyethylene glycol based preparation) or a low volume bowel preparation (sodium picosulfate, a stimulant laxative, magnesium oxide and anhydrous citric acid (SP/MC)). Both agents will either be administered as full dose the evening before or as split-dose on the evening before and on the day of the procedure.
The purpose of our study is to determine if a 4L bowel cleansing agent is more effective than a low volume bowel preparation, and if the time of dosing (single dose night before vs split dose) of the bowel preparation results in better bowel cleansing in participants undergoing colonoscopy. Eligible participants undergoing colonoscopy with conscious sedation will be randomly assigned to one of two bowel preparations and one of two dosing schemas of bowel preparation. Participants not eligible for conscious sedation and are undergoing colonoscopy with general anesthesia will be randomized only to the single dose arms of the study. Participants will complete a questionnaire while drinking the bowel preparation to determine timing and tolerability of the bowel preparation.

Percentage of Participants With Satisfactory Bowel Cleansing
Bowel cleansing efficacy will be measured using the Boston Bowel Prep Scale (BBPS). The BBPS divides the colon into 3 segments (right, transverse, left); each is scored from 0-3 (0=colonic mucosa not seen due to solid stool that cannot be cleared, 1=only a portion of the mucosa of the colon segment is seen due to staining, residual stool and/or opaque liquid, 2=minor amount of residual staining, small fragments of stool and/or opaque liquid but mucosa of colon segment is seen well, and 3=entire mucosa is seen well with no residual staining, small fragments of stool or opaque liquid). A total BBPS score of 6 or greater AND 2 or greater in all segments will be defined as satisfactory bowel prep. BBPS score of less than 6 or less than 2 in any segment of the colon will be taken as unsatisfactory bowel cleansing in the final analysis.
