About the study

The purpose of this research is to compare patient preferences for two bowel preparation options: low-volume tablets (Suflave/Sutab) versus the standard colon preparation using Golytely (polyethylene glycol). The study aims to enroll approximately 300 patients, who will be randomly assigned to one of the two preparation methods in a 2:1 ratio prior to their scheduled colonoscopy appointments. Surveys will be conducted both before and after the procedures.

This project will be conducted over a 12-month period and seeks to compare patient experience of both preparation methods in an outpatient setting. The study will evaluate the rate of preparation completion, patient satisfaction, tolerance of the solutions, and the endoscopic adequacy of each method.

Eligible participants are patients aged 18 or older with upcoming colonoscopy appointments who can provide informed consent in English or Spanish. There is no health risks associated with this study, as both bowel preparation methods are FDA-approved and commonly used in clinical practice.
