Pre-Packaged Low-Residue Diet Assisting Bowel Preparation in Patients With Inflammatory Bowel Disease

The project workflow comprises three consecutive phases: In the initiation phase, key activities include designing the study protocol, developing a bowel preparation assessment questionnaire, and establishing collaborative multicenter partnerships. During the implementation phase, subjects will be randomized into two arms-the control arm receiving conventional low-residue diet and the intervention arm administered Maifu Changqing® Complete Nutritional Formula Powder-with both regimens initiated 24 hours prior to colonoscopy. Clinical data will be systematically collected while Case Report Forms (CRFs) from all participating centers are centrally aggregated. The conclusion phase focuses on CRF quality control through standardized verification procedures to ensure data integrity, completeness, and objectivity according to Good Clinical Practice (GCP) standards.
