Yoga and Bolus Lukewarm Saline as Rapid Colonoscopy Preparation

February 17, 2015 updated by: Vijaypal Arya MD, FACP, FACG, AGAF., Arya, Vijaypal, M.D., P.C.

A Single Blind, Parallel Group, Randomized Controlled Trial Comparing Solution PEG Based Colon Preparation (HalfLytely) Versus Bolus Luke Warm Saline (Shudh) and Yoga Exercise for Large Bowel Cleansing Prior to Colonoscopy

A quality colonoscopy examination remains as the gold standard for colorectal cancer screening, but effective large bowel cleansing prior to colonoscopy is still not achieved in all cases that undergo the procedure. Currently, the most widely used cleansing methods employ balanced electrolyte-polyethylene glycol (PEG) solutions. However, a very large volume of PEG solution is required for it to be effective, and many patients refuse to drink a sufficient amount due to non-palatability. In this study, the investigators compare a novel colon preparation method--bolus lukewarm saline with yoga exercise--with a PEG based solution (HalfLytely) for large bowel cleansing.

Detailed Description

Effective large bowel cleansing prior to colonoscopy is still not achieved in all cases that undergo the procedure. The use of balanced electrolyte-polyethylene glycol (PEG) solution have improved the cleansing results and shortened the time needed for preparing the bowel. The problem with using PEG solution alone is the relatively large volume of the solution that the patients need to drink. The recommendation is to drink the solution until diarrhea fluid is clear and often 4 L or more is needed. Many patients refuse to drink the sufficient volume needed to get a clean colon due to non-palatability. Good results of bowel cleansing have also been reported with sodium phosphate solution or tablets.

The fluid volume needed to drink along with sodium phosphate is generally no problem but this regimen causes electrolyte disturbances and renal insufficiency that usually are subclinical and of no significance. Several combinations of PEG solution and laxatives have been tested before. Low-volume PEG plus Bisacodyl preparation was better tolerated but it was not as effective as standard large-volume PEG and associated with abdominal cramping.

PEG solution 2L and Bisacodyl is used for large bowel cleansing in many centers in the United States and is the standard regimen used in our colonoscopy unit. In this study the investigators compare this standard regimen taken day before colonoscopy with Bolus lukewarm saline solution taken orally with yoga exercise on the day of colonoscopy.

The result of large bowel cleansing is evaluated during the colonoscopy according to a validated scoring method. Time to the first bowel movement and total preparation time are compared. Solution palatability, patient acceptability, abdominal symptoms, discomfort and subjective grading of how hard/easy it was to complete the cleansing program are evaluated with questionnaires.

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.

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
Efficacy of Large Bowel Cleansing as Assessed by the Physician Performing the Colonoscopy
Time Frame: Within 48 hours of bowel preparation
The primary endpoint was the "success" rate of the preparations. Preparation efficacy was evaluated by a single, blinded endoscopist (V.A.), who performed all of the colonoscopies. The evaluation involved the rating of six anatomical segments of the colon (rectum, sigmoid, descending colon, transverse colon, ascending colon and cecum) on the 5 point Arya Bowel Prep Scale (ABPS). Aggregating the segmental scores resulted in overall scores. Grade A was defined as a total overall score of 19-24, grade B as a score of 13-18, grade C as a score of 7-12, and grade D as a score of 0-6. Grade A or B preparation was considered "successes", while grade C or D was considered "failures." To assess the reliability of ABPS, we trained 4 gastroenterologists and 3 fellows.
Within 48 hours of bowel preparation

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
Palatability of Bowel Prep
Time Frame: Upto 24 weeks
Patients completed a symptom questionnaire where they rated solution palatability of their assigned prep on a 1-5 Likert scale. A rating of more than 3 was considered as "Palatable".
Upto 24 weeks
Subjective Grading by Patients on Willingness to Repeat the Large Bowel Preparation.
Time Frame: Upto 24 weeks
Subjects rated the SCC as "Willingness to repeat the same prep in future"
Upto 24 weeks
Patient-reported Adverse Events.
Time Frame: Upto 24 weeks
Patients from both groups reported adverse events in a symptom questionnaire.
Upto 24 weeks
Total Preparation Time
Time Frame: Upto 24 weeks
