Patients Judging Bowel Preparation by Using SMARTPHONE Application

Study Overview
=================
Brief Summary
-----------------
High-quality bowel preparation is a prerequisite for colonoscopy. Few studies have evaluated visual aids as a means of improving the quality of bowel preparation. We assess the effect of patient-judging dose adjustment of bowel preparation solution for bowel preparation using SMARTPHONE application on the quality of bowel preparation.

Detailed Description
-----------------
This was a randomized, prospective, endoscopist-blinded clinical trial in which the efficacy of SMARTPHONE application on the bowel cleansing was inspected. A intervention patients take the picture of stool using SMARTPHONE camera application, and then assess the bowel cleansing result. If the result is Pass, they stop the addition of bowel preparation agent. but the result is Fail, so they have the additive bowel preparation agent and repeat using the SMARTPHONE application. After the bowel preparation, Endoscopists, who were blinded to the study group of the patient, immediately completed the Ottawa scale after procedure.
