The Interval Between the Time of Second PEG Dose and the Start of the Colonoscopy (TOSP)

October 4, 2011 updated by: Eun Hee Seo, Inje University
As the duration of the interval between the time of last preparation-agent dose and the start of the colonoscopy is increasing, the quality of bowel preparation will be worse.

Study Overview

Detailed Description

The aim of the present studies is to determine how the duration of the interval of the time of last preparation dose and the start of colonoscopy affects the quality of the bowel preparation and when the proper timing of the colonoscopy is after completion of last preparation regimen
