About

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.

Full description

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.

Enrollment: 14 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

14 participants in 4 patient groups

Group A

Active Comparator group

Description:

Participants in Group A will begin drinking the bowel preparation Golytely (4 liter Polyethylene glycol based preparation) at 4:00 PM on the day before colonoscopy - an 8-ounce glass of the bowel preparation every 10 minutes. Participants must finish drinking the bowel preparation by 7:00 PM, and may continue to drink clear liquids until midnight.

Treatment:

Drug: Golytely

Group B

Active Comparator group

Description:

Participants in Group B will begin drinking the bowel preparation Golytely (4 liter Polyethylene glycol based preparation) at 4:00 PM on the day before colonoscopy - an 8-ounce glass of the bowel preparation every 10 minutes for a total of 8 glasses, and must complete drinking the bowel preparation by 5:30 PM. Participants may continue to drink clear liquids until midnight. The next day, 4 hours before the scheduled time of colonoscopy, participants will be asked to drink an 8 ounce glass of bowel preparation every ten minutes for a total of 8 glasses over no more than 1.5 hours. Participants may continue to drink clear liquids until 2 hours before the scheduled time of colonoscopy.

Treatment:

Drug: Golytely

Group C

Active Comparator group

Description:

Participants in Group C will begin drinking the bowel preparation Clenpiq (sodium picosulfate, magnesium oxide, and citric acid) at 4:00 PM on the day before colonoscopy. Participants will be asked to drink 5 ounces of the bowel preparation and at least five (5) additional 8-ounce glasses of clear liquids by 9:00 PM. At 10:00 PM, participants will drink another 5 ounces of the bowel preparation, and will then be asked to drink at least three (3) additional glasses of clear liquids by midnight.

Treatment:

Drug: Clenpiq

Group D

Active Comparator group

Description:

Participants in Group D will begin drinking the bowel preparation Clenpiq (sodium picosulfate, magnesium oxide, and citric acid) at 4:00 PM on the day before colonoscopy. Participants will be asked to drink 5 ounces of the bowel preparation and at least five (5) additional 8-ounce glasses of clear liquids by 9:00 PM, and may continue drinking clear liquids until midnight. The next day, 4 hours before the scheduled time of colonoscopy, participants will drink another 5 ounces of the bowel preparation and at least three (3) 8 ounce glasses of clear liquids within the next 2 hours. Participants may continue to drink clear liquids until 2 hours before the scheduled time of colonoscopy.

Treatment:

Drug: Clenpiq
