Summary

The goal of this clinical trial is to learn about bowel preparation methods compared between standard techniques and enhanced education with application for elective colonoscopy. The main questions it aims to answer are: Which bowel preparation method results in an adequate bowel preparation rate? Participants will: * Random to 1:1 ratio to be educated via the smartphone application (APP group) or the standard education (control group). * Received the same purgative regimen and diet restriction. * Endoscopist-blinded colonoscopy the participants and give score of bowel preparation scale (use Boston Bowel Preparation Scale)

Detailed description

A prospective, endoscopist-blinded, randomized, controlled trial will conducted at the GI endoscopy center, Siriraj Hospital, Bangkok, Thailand. Patients will be divided into 2 groups in a 1:1 ratio using a computer-generated randomization method, with a block of four randomizations. Written informed consent will be obtained from all participants before their enrolment in the study. * Patients in the control group received verbal instructions for preparation before endoscopy from the endoscopy nurse, along with pamphlets containing relevant information. This instructional material encompassed details regarding a purgative regimen, instructions on its administration, dietary restrictions preceding colonoscopy, and medication adjustments necessary for some patients. * Patients in the application group communicated via Line applications (APP group) with guidance on preparation before colonoscopy through video media. The registration process will entail providing basic information, including the patient's name and hospital identification number, along with the scheduled endoscopy appointment date, with strict adherence to privacy protocols. Subsequently, a trained research assistant will encourage patients to utilize the application. The video can inform the application via YouTube. The content presented in the video corresponded identically to the verbal instructions and pamphlet provided to participants in the control group, covering topics such as the purgative regimen, dietary restrictions, and medication adjustments. All participants will receive the same split-dose high-volume purgative regimen. Two liters of polyethylene glycol (PEG) solution regarding the composition of Colyte (hospital-based preparations) will be administered at 6-8 PM on the day before the colonoscopy, followed by 750 ml of PEG solution at 5-6 AM on the colonoscopy day. Colonoscopies will be performed by an experienced endoscopist under intravenous sedation within 6 hours after the last preparation regimen.
