July 31, 2020 updated by: Cátia Vanessa Meixedo Arieira, Hospital da Senhora da Oliveira

Comparative, Prospective and Randomized Study of Two Preparations for the Study of the Colon Through Colonoscopy

Compare the quality of bowel preparation between two groups of patients, who will undergo two different preparations: 1. Moviprep + diet; 2. Plenvu + diet

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Detailed Description

The quality of bowel preparation is essential for the success of a colonoscopy, reducing colonoscopy duration, and increasing the rate of cecal intubation and of polyp detection. There are several types of preparations available on the market and, irrespective of the choice, the split-dose regimen should be followed. A reduced volume preparation makes the process easier and more tolerable, increasing adhesion. Regarding the diet to be applied before the examination, there are no advantages to a liquid diet compared to a low fiber diet, and there is no evidence on the duration of the diet. In addition, a restrictive diet has an impact on satisfaction and also on adherence to treatment.

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.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
1LPEG
Patients receiving 1LPEG who had a colonoscopy in the morning were advised to follow a day-before dosing regimen, where, at 7:00 pm the day before the colonoscopy, they prepared the Dose 1 sachet in 500 mL of water and consumed it over a period of 30 minutes, followed by 500 mL of clear liquids. The second dose was then taken at 11:00 pm by mixing the two Dose 2 sachets in a single glass of 500 mL of water and consuming them over 30 minutes, followed by 500 mL of clear liquids. If the colonoscopy was scheduled for the afternoon, the same dosing instructions were given, but the first dose was taken at 7:00 am on the day of the procedure, and the second dose began at 10:00 am.
Drug: PLENVU
Bowel preparation for a colonoscopy
2LPEG
Patients receiving 2LPEG who had a colonoscopy in the morning were asked to follow a similar day-before dosing regimen, where, at 7:00 pm the day before the colonoscopy, the first 1L dose was consumed over a 1-hour period, followed by the second dose at 11:00 pm. For 2LPEG patients with procedures in the afternoon, they took Dose 1 at 7:00 am and Dose 2 at 10:00 am. Any patient receiving 2LPEG was also told to consume 1L of clear liquids during the preparation procedure.
Drug: MoviPrep
Bowel preparation for a colonoscopy

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 between the two groups of patients
Time Frame: Patients were instructed to report any possible adverse events for up to 1 month after the procedure.
The colonoscopist assessed each of the 3 colon segments on the BBPS and assigned each a score of 0 to 3. Successful overall bowel preparation is defined as a BBPS score of >6 with no individual segment scoring <2.
Patients were instructed to report any possible adverse events for up to 1 month after the procedure.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Degree of satisfaction with the two bowel preparation
Time Frame: Patients were instructed to report any possible adverse events for up to 1 month after the procedure.
The level of patient satisfaction with the 2 bowel preparation regimens was also assessed through a comparative analysis of the patient satisfaction questionnaire
Patients were instructed to report any possible adverse events for up to 1 month after the procedure.
Quality of bowel preparation in patients who had a morning or afternoon colonoscopy and those who received written, oral and additional telephone re-education on the day before the colonoscopy versus written and oral information only.
Time Frame: Patients were instructed to report any possible adverse events for up to 1 month after the procedure.
The colonoscopist assessed each of the 3 colon segments on the BBPS and assigned each a score of 0 to 3. Successful overall bowel preparation is defined as a BBPS score of >6 with no individual segment scoring <2.
Patients were instructed to report any possible adverse events for up to 1 month after the procedure.
