Prepackaged Nutritional Formulations Versus Restricted Diet for Bowel Preparation

April 5, 2021 updated by: Ningbo No. 1 Hospital

Comparing the Efficacy and Tolerability of a Prepackaged Semisolid Nutritional Formulations With a Restricted Diet for Colonoscopy Preparation: A Randomized Clinical Trial.

In order to analyze the effectiveness and patient tolerance of the two bowel preparation regimens, the investigators will compare prepackaged semisolid nutritional formulations and restricted diet. The aim was to demonstrate that prepackaged semisolid nutritional formulations is not inferior in overall quality of intestinal preparation to restricted diet in subjects undergoing colonoscopy.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

EXPERIMENTAL: prepackaged group

All colonoscopy were performed in the afternoon. The day before the colonoscopy: 3 bags of pre-packaged food were used for diet preparation. All the patients drink single dose of 60g Polyethylene Glycol (PEG-4000) with 1L water at a rate of 250 ml every 15 min in the evening.

On the day of the colonoscopy: a bag of pre-packaged food were used for breakfast. 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.
Other: prepackaged semisolid nutritional formulations

On the day of the colonoscopy: a bag of pre-packaged food were used for breakfast.
ACTIVE_COMPARATOR: restricted diet group

All colonoscopy were performed in the afternoon. The day before the colonoscopy: restricted diet prepared by patients were used for diet preparation. All the patients drink single dose of 60g Polyethylene Glycol (PEG-4000) with 1L water at a rate of 250 ml every 15 min in the evening.

On the day of the colonoscopy: restricted diet prepared by patients were used for breakfast. 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Quality of Bowel Preparation
Time Frame: 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)
1 Day of colonoscopy
