App-Based Education and Low-Residue Diet for Colonoscopy Preparation

This prospective, randomized, evaluator-blind, parallel-group trial is designed to objectively compare the effectiveness of Advanced Bowel Preparation versus Traditional Bowel Preparation in patients undergoing colonoscopy. In this study, "naive patients" are defined as individuals who have never used Bowklean® as a bowel cleansing agent, or those who may have previously used other bowel preparation regimens but have not undergone any bowel cleansing procedure within the past three years. The Traditional Bowel Preparation approach consists of standard paper-based educational handouts and self-managed low residue dietary restrictions. In contrast, the Advanced Bowel Preparation integrates a smartphone based educational app with a Prepackaged Low-Residue Diet. All participants will use Bowklean®, a bowel preparation agent combining sodium picosulfate, magnesium oxide, and anhydrous citric acid. The primary endpoint is the percentage of subjects that achieve adequate cleansing (score ≧ 6) in the Boston Bowel Preparation Scale (BBPS). The secondary endpoints include the percentage of subjects that achieve excellent cleansing (score ≧ 8) in the BBPS, mean score in different colon segments (right, transverse, left), which are assessed with the BBPS, adenoma detection rate, sessile serrated polyp detection rate, and patient satisfaction.

Comparison of Bowel Preparation Using 2 Liter Polyethylene Glycol Regimen Plus Elobixibat Versus 4-Liter Polyethylene Glycol Regimen

Comparison of bowel preparation using 2 liter polyethylene glycol regimen plus elobixibat Versus 4-Liter polyethylene glycol regimen. This study based on hypothesis that show Boston bowel preparation scale which 2L PEG regimen plus Elobixibat have result no significant difference from 4L PEG regimen
