Mizone vs Water for Bowel Preparation.

Not Applicable

Completed

• Conditions: Bowel Preparation
• Interventions: Drug: PEG-Mizone; Drug: PEG-ELS

• Registration Number: NCT04247386
• Lead Sponsor: Ningbo No. 1 Hospital

Brief Summary

In order to analyze the effectiveness and patient tolerance of the two bowel preparation regimens, we will compare Polyethylene Glycol Electrolytes Powder (PEG-4000) and Mizone with PEG-ELS. The aim was to demonstrate that polyethylene glycol electrolyte powder (PEG-4000) and Mizone is not inferior in overall quality of intestinal preparation to PEG-ELS in subjects undergoing colonoscopy.

Arm && Interventions

Group	Intervention	Description
PEG-Mizone prep	PEG-Mizone	The evening before the colonoscopy: The patients who are randomized to the " PEG-Mizone prep " arm will drink single dose of 60g Polyethylene Glycol (PEG-4000) with 0.6L Mizone+0.4L water at a rate of 250 ml every 15 min. On the day of the colonoscopy: The patients who are randomized to the " PEG-Mizone prep " arm will drink single dose of 120g Polyethylene Glycol (PEG-4000) with 1.2L Mizone+0.8L water 4-6 h before colonoscopy at a rate of 250 ml every 15 min.
PEG-ELS prep	PEG-ELS	The evening before the colonoscopy: In the PEG-ELS prep group, all the patients drink single dose of 60g Polyethylene Glycol (PEG-4000) with 1L water at a rate of 250 ml every 15 min. On the day of the colonoscopy: all the patients drink single dose of 120g Polyethylene Glycol (PEG-4000) with 2L water 4-6 h before colonoscopy at a rate of 250 ml every 15 min.

Primary Outcome Measures

Name	Time	Method
Quality of Bowel Preparation	1 Day of colonoscopy	The OBPS，a scoring system with scores between 0 and 14, where 0 is the best score，divides the colon into 3 segments (right, transverse and rectosigmoid colon); each is scored from 0-4 (0=excellent, If it is necessary to suction liquid stool to adequately see the colonic wall, a score of 2 (fair) is given; if it is necessary to wash and to suction, a score of 3 (poor) is given. The remaining scores fall into place around these anchors. ). A score 0-2 is added to indicate the total amount of luminal fluid.(0=The total amount of fluid in the colon is very small,1=a moderate volume of fluid overall in the colon,2=a large volume of fluid overall in the colon)

Secondary Outcome Measures

Name	Time	Method
Adverse event rate	3 days	Including Electrolyte disorders requiring clinical treatment, etc.
patient tolerability of bowel preparation	1 Day of colonoscopy	On the day of the patient's colonoscopy, each patient will complete another form regarding their bowel preparation experience with a modified 5-point Likert scale for ease of use (score 5-1: very easy, easy, tolerable, difficult or very difficult).
