A low-residue diet improved patient satisfaction with split-dose oral sulfate solution without impairing colonic preparation.

Background: Preprocedural dietary restrictions have been identified as a common reason potential candidates for colorectal cancer screening do not undergo colonoscopy as recommended.

Objective: To study whether a low-residue diet impacts bowel preparation with oral sulfate solution.

Design: Endoscopist blinded, prospective, randomized controlled trial.
