Objectives

Narrative objectives1

With the increasing prevalence of colorectal cancer and inflammatory bowel disease, the necessity of colonoscopy has become increasingly evident. Colonoscopy requires bowel preparation, which typically includes ingesting polyethylene glycol electrolyte lavage solution (PEG-ELS). However, the large volume of PEG-ELS is often a challenge and reducing this burden could reduce the overall discomfort of colonoscopy. This study assessed whether a prepackaged low-residue diet (PLRD; Clear Through) could reduce the required volume of PEG-ELS (Moviprep).
