What this trial studies

About 300 adults scheduled for outpatient colonoscopy will be randomized in a 2:1 ratio to receive either a low-volume tablet preparation (Sutab/Suflave) or standard polyethylene glycol solution (Golytely). Participants will complete brief surveys before and after their procedures over a 12-month enrollment period to capture completion rates, satisfaction, and tolerability. Endoscopists will rate bowel cleanliness to compare the endoscopic adequacy of each method. The trial will compare patient-reported experience and objective cleansing outcomes between the two prep strategies.

Who should consider this trial

Good fit: Adults aged 18 and older scheduled for outpatient colonoscopy who can provide informed consent in English or Spanish are ideal candidates.

Not a fit: Pregnant or nursing people, those under 18, incarcerated individuals, or anyone unable to give informed consent would not be eligible and thus would not benefit from participating.

Why it matters

Potential benefit: If successful, a more tolerable prep could make bowel cleansing easier, increase completion rates, and improve the quality of colonoscopy screenings.

How similar studies have performed: Prior trials have shown low-volume tablet preps like Sutab can provide similar cleansing efficacy to PEG solutions and are often better tolerated and preferred by patients.
