Summary

Optimal bowel preparation is essential for colonoscopy efficacy and safety. Mucosal visualization during colonoscopy is often limited by residual stool, bubbles, bile, intraluminal fluid, and debris, which increase the risk of missing flat adenomas or other small lesions.Therefore, intestinal preparation is necessary to remove residual materials prior to endoscopy.

A combined agent, low-dose PEG with ascorbic acid (PEG-Asc), is one low-volume solution commonly used in Korea (Coolprep®; TaeJoon Pharmaceuticals, Seoul, Korea). However, practitioners have noted an increased incidence of bubble formation with this preparation method.

To the investigators knowledge, no previous study has assessed colon preparation in patients administered simethicone.

The purpose of this study was to compare the quality of bowel preparation and compliance between PEG-Asc and PEG-Asc with simethicone. The effectiveness of adding simethicone as an antifoaming agent to improve bowel cleansing for colonoscopy was evaluated in terms of bowel preparation scale and bubble score, and the compliance of both patients and endoscopists was also investigated using a questionnaire.

Conditions

Interventions

DRUG

PEG-Asc

received 1 L solution of PEG-Asc at 7 p.m the evening before colonoscopy and another 1 L solution of PEG-Asc at 5 hours before procedure

DRUG

PEG-Asc with simethicone

received 1 L solution of PEG-Asc at 7 p.m the evening before colonoscopy and another 1 L solution of PEG-Asc at 5 hours before procedure. Two packs (200 mg/10 mL each) of simethicone (400 mg) was mixed with last 500 mL of additional clear fluid.
