Split Dose Golytely With Amitiza Pretreatment Versus Split Dose Golytely Plus Placebo in Outpatient Colonoscopy

October 3, 2012 updated by: Joel Z. Stengel, Brooke Army Medical Center

Single Dose Lubiprostone Along With Split-dose PEG Solution Without Dietary Restrictions for Bowel Cleansing Prior to Colonoscopy, a Randomized, Double-blind, Placebo Controlled Trial

The primary outcomes of this procedure will be: 1. The cleanliness of the prep as measured by the Ottawa Scale (attachment a). Secondary outcomes will be: 1. Patient satisfaction with the prep measured by 5 point Likert scale (attachment b); 2. Procedure time; 3. The number and size of polyps detected on examination.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The Overall Cleanliness of the Prep as Measured by the Ottawa Scale
Time Frame: measured upon completion of the colonoscopy, colonoscopies completed during the course of the study (approximately 4 month period)
Bowel cleansing was evaluated with the Ottawa bowel preparation scale by each endoscopist during the endoscopy. Neither the endoscopist nor the endoscopy nurse was aware of the bowel preparation used prior to the colonoscopy. The Ottawa bowel preparation scale is a validated tool and was used in this study to provide a reliable quality assessment of the bowel preparation used for colonoscopy. This validated scale rates each section of the colon, the right, the mid, and the rectosigmoid colon, on a 5-point scale (0-4), as well as a global 3-point rating for overall colonic fluid (0-2). The total score ranges from 0 to 14. An excellent preparation with little fluid would score 0-3, a good preparation 4-6, while scores higher than 7would indicate progressively worsening bowel preparations. A completely unprepared colon would score 11-14, depending on the amount of colonic fluid
measured upon completion of the colonoscopy, colonoscopies completed during the course of the study (approximately 4 month period)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Patient Satisfaction With the Prep Measured by 5 Point Likert Scale
Time Frame: measured after completion of the bowel preparation and prior to the colonoscopy, completed during the course of the study (approximately 4 month period)
The participants completed a survey prior to the colonoscopy that graded their overall satisfaction with the bowel preparation. The subjects rated the survey questions on a 5-point Likert scale where 1 = severely distressing, 2=distressing, 3=bothersome, 4=mild, and 5=none.
measured after completion of the bowel preparation and prior to the colonoscopy, completed during the course of the study (approximately 4 month period)
Procedure Time
Time Frame: measured upon completion of the colonoscopy, colonoscopies completed during the course of the study (approximately 4 month period)
Procedure time refers to the total length of time required to complete the colonoscopy
measured upon completion of the colonoscopy, colonoscopies completed during the course of the study (approximately 4 month period)
The Number of Polyps Detected on Examination
Time Frame: measured upon completion of the colonoscopy, colonoscopies completed during the course of the study (approximately 4 month period)
The number of colon polyps detected during the colonoscopy.
measured upon completion of the colonoscopy, colonoscopies completed during the course of the study (approximately 4 month period)
