Abstract
Background and Aims: Colonoscopy surveillance depends on effective bowel preparation. Inadequate bowel preparation can lead to inaccurate clinical diagnosis, insufficient visualization of the colon and increased risk of missed diagnosis. This study aimed to compare the efficacy and safety of a novel Capsule Bowel Preparation (RitePrep), high-volume (2L) polyethylene glycol electrolyte solution (MoviPrep®) and low-volume (1L) polyethylene glycol electrolyte solution (Plenvu™).Methods: Patients (n = 120) were divided into three groups and were administered either RitePrep, MoviPrep® or Plenvu™ as a pre-colonoscopy bowel preparation followed by a colonoscopy at a single center. Validated Boston Bowel Preparation Score (BBPS) and bubble score were used to evaluate bowel cleanliness. Blood tests were also evaluated. The scores and the blood results were analyzed using Kruskal-Wallis and Chi-squared tests.Results: A total of 120 patients (median age of 55; 57 males) [RitePrep (n = 40), MoviPrep® (n = 40) and Plenvu™ (n = 40)] were included in the study. RitePrep was the most effective method for cleansing the bowel, with a significantly higher median BBPS compared to MoviPrep® and Plenvu™ (p = 0.006 and 0.024, respectively). Nearly 50% of the patients in Plenvu™ group showed increased serum osmolality disturbance. Nausea and vomiting were higher in Plenvu™ and MoviPrep® groups than RitePrep group.Conclusions: RitePrep was demonstrated to be a more effective and safe preparation than the other two preparations. RitePrep was not only well-tolerated by all patients; the preparation sufficiently cleared the ascending, transverse, and descending colon, enabling optimal visualization for the clinician. RitePrep was also much safer than the comparators, with no alteration in electrolytes measured. For both the clinician and the patient, RitePrep was the preferred preparation.
Highlights
The effectiveness of a colonoscopy procedure relies on an adequately prepared bowel
Tolerability is a major factor in good bowel preparations, with the poor palatability of bowel preparation often leading to patients’ trepidation in undergoing the screening colonoscopy procedure [1]
At the Center for Digestive Diseases, we developed a novel Capsule Bowel Preparation (RitePrep)
Summary
The effectiveness of a colonoscopy procedure relies on an adequately prepared bowel. Bowel preparation aims to completely evacuate and clean the bowel before conducting a colonoscopy procedure, which allows the doctor to properly examine the colon. Poor bowel preparation leads to impaired detection rate of polyps [2]. Effective bowel preparations have yet to achieve acceptance by both the clinician and the patient. Many patients cannot tolerate the currently available bowel preparations which often sacrifice palatability and can cause severe electrolyte disturbances [4]. Tolerability is a major factor in good bowel preparations, with the poor palatability of bowel preparation often leading to patients’ trepidation in undergoing the screening colonoscopy procedure [1]. Colonoscopy surveillance depends on effective bowel preparation. Inadequate bowel preparation can lead to inaccurate clinical diagnosis, insufficient visualization of the colon and increased risk of missed diagnosis. This study aimed to compare the efficacy and safety of a novel Capsule Bowel Preparation (RitePrep), high-volume (2L) polyethylene glycol electrolyte solution (MoviPrep®) and low-volume (1L) polyethylene glycol electrolyte solution (PlenvuTM)
