A pilot study for using high-volume colon irrigation bowel preparation for colon capsule endoscopy shows feasibility of adequate bowel prep with high patient satisfaction

Abstract

A feasibility study was performed to test a bowel preparation (BP) method that would improve patients’ experience of colon capsule endoscope (CCE) while retaining clinical adequacy. Specifically, the use of high-volume colon irrigation with the Hygieacare® System, HygiPrep™, was tested in conjunction with Medtronic’s PillCam COLON 2 Capsule. This prospective, single-center, and IRB-approved study evaluated HygiPrep use prior to the PillCam COLON 2 procedure instead of the standard split-polyethylene glycol-electrolyte (PEG) oral prep. The study was performed at Austin Gastroenterology (Austin, TX), and all capsule video files were forwarded to a Central Reader to evaluate and compile a study report. Six of the seven (86%) subjects completed both the HygiPrep and PillCam COLON 2 exams and were graded as excellent, good, or adequate by the Central Reader. Patients’ feedback reported positive satisfaction scores for both the HygiPrep and the PillCam COLON 2 procedures. These results support our hypothesis that HygiPrep was as effective as Split-PEG BP. We suggest that the HygiPrep, is a suitable BP for CCE, providing adequate BP and high patient satisfaction.
