Patients Judging Bowel Preparation by Using SMARTPHONE Application

Patients Judging Dose Adjustment of Bowel Preparation Solution for Bowel Preparation by Using SMARTPHONE Application: A Pilot Study

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.

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.

Inclusion Criteria:

• Patient who are scheduled for colonoscopy Available to use the SMARTPHONE application and smartphone camera

Exclusion Criteria:

• known or suspected bowel obstruction known pregnancy, breast feeding known allergy to PEG presence of severe illness(renal failure, congestive heart failure, liver failure,), refusal of consent to participate in the study not available to use the SMARTPHONE application and SMARTPHONE camera
