Assessment of Safety, Quality, and Acceptance of a Bowel Preparation Using a Food Kit With Laxatives
2026年5月18日 更新者：Joseph Spataro
A Single-Center, Randomized, Prospective, Single-Blinded Study to Assess the Safety, Quality, and Tolerance of a Bowel Preparation Using a Food Kit With Laxatives in a United States Veteran Population
The main purpose of this research study is to learn if an alternative bowel preparation (bowel prep) for colonoscopy is safe, tolerable and effective as compared to the standard bowel prep.
Participants are randomly assigned to receive one of the following bowel cleansing regimens for colonoscopy.
- Standard Bowel Prep which includes a clear liquid diet the day before the scheduled procedure and two doses of a laxative, polyethylene glycol 3350 (PEG-3350) taken with 4 liters of water.
- Happy Colon Foods Bowel Prep which begins the day before the scheduled procedure and contains various low residue foods (foods that are easily digested and absorbed), and seven doses of laxatives including PEG-3350 taken with a total of about 4 liters of water, senna tablets, and one dose of magnesium citrate.

実験的：Experimental: Food Kit with Laxatives (Happy Colon Foods)
Patients receive a commercially available prepackaged food and laxative kit (Happy Colon Foods) starting 24 hours before colonoscopy, including a low-residue diet and intermittent laxative regimen with PEG-3350 powder, senna tablets, and a single dose of magnesium citrate, following written and visual instructions.
|
Low-residue diet food items and scheduled doses of PEG-3350, senna, and magnesium citrate prior to the colonoscopy

アクティブコンパレータ：Control: Standard GoLYTELY Split-Dose Prep
Patients receive standard colonoscopy bowel preparation using a clear liquid diet for 24 hours before the procedure and split-dose 4 L polyethylene glycol 3350 electrolyte solution (PEG-3350; GoLYTELY) prior to the scheduled colonoscopy.
|
Split-dose 4 L PEG-3350 electrolyte lavage solution taken the day before and morning of colonoscopy, combined with 24-hour clear liquid diet.
