- Conditions
- Patient Satisfaction and Efficacy of Bowel-preparation
- Interventions
- Other: Bowel-prep (Plenvu as experimental arm)
- Registration Number
- NCT05192551
- Lead Sponsor
- Karolinska Institutet
- Brief Summary
An multi-center, observational study where we compare the current standard, PEG-based bowel-prep to a (in Sweden) recently approved and introduced low volume (1 litre) PEG-based bowel-prep (Plenvu) in a clinical routine situation.
The investigators will investigate if there are any differences in patient satisfaction and efficacy of the different bowel preparations
- Detailed Description
When performing Colonoscopy it is essential to use a bowel-prep that is highly effective and at the same time tolerable to intake for the patient to ensure that the patients intakes the recommended amount of the bowel-prep.
This in order to be able to detect pathological findings in the mucosa. Currently in n Sweden the standard bowel-prep used in most endoscopy-units is high volume bowel preps (4 litres) in split dose. It can be difficult for the patient to intake the whole dose wish can lead to a sub-optimal bowel-cleansing.
Recently, in Sweden, a new low-volume bowel-prep has been approved and introduced (Plenvu).
This preparation, totally 1 litre of bowel prep given in a split dose is potentially easier for the patient to intake but it is essentially to ensure that the efficacy i at least as good as the current high dose preparation. In this study the investigators will therefore investigate patient satisfaction and efficacy of the different bowel preparations, comparing Plenvu with the current standard bowel-prep regime at the participating endoscopy units.
Five endoscopy units participates in this study (Endoskopi City, Stockholm, Endoskopienheten i Malmö, Endoskopienheten i Linköping, Endoskopienheten i Örebro, Endoskopienheten Ersta sjukhus, Stockholm).
In each endoscopy unit 100 consecutive patients will be prescribed Plenvu and another 100 consecutive patients will be prescribed the current standard bowel-prep at the actual unit. a total of 1000 patients will participate in the study.
The currently used bowel-preps at the different endoscopy units are: Vistaprep, Laxabon and Movprep This is a study performed in a clinical context and no randomization is made. When arriving to the endoscopy unit patients are asked to participate in the study and if willing to participate patients will sign an informed consent-form.
Before the colonoscopy the patients fills in a questionnaire about the bowel-prep experience concerning; smell, taste, overall experience (five graded scales) of the prep. In the questionnaire patients are also asked how much of the prescribed bowel-prep that have been digested and how much extra fluid the patient have been drinking during the preparation process. The patients are also asked about if they have been experienced nausea or been vomiting.
After the colonoscopy, the gastroenterologist performing the endoscopy fills in the Boston Bowel Preparation Scale (BBPS) as a measure of how successful the bowel cleansing has been.
Based on this information the investigators will compare patient satisfaction and efficacy of the bowel-cleansing in the group that has been prescribed Plenvu to the group that has been prescribed the endoscopy-units standard bowel-prep

Group Intervention Description Vistaprep Bowel-prep (Plenvu as experimental arm) A standard high volume bowel-prep, used for a long time in Sweden. The dose is 2000 ml x 2. The first dose is given the evening before the colonoscopy and the second dose is given 4-5 hours before the colonoscopy. Plenvu Bowel-prep (Plenvu as experimental arm) A new type of low-volume bowel-prep recently approved and introduced in the Swedish market. The dose is 500 ml x 2, The first dose is given the evening before the colonoscopy and the second dose is given 4-5 hours before the colonoscopy. Laxabon Bowel-prep (Plenvu as experimental arm) A standard high volume bowel-prep, used for a long time in Sweden. The dose is 2000 ml x 2. The first dose is given the evening before the colonoscopy and the second dose is given 4-5 hours before the colonoscopy. Movprep Bowel-prep (Plenvu as experimental arm) A standard median volume bowel-prep, used for a long time in Sweden. The dose is 1000 ml x 2. The first dose is given the evening before the colonoscopy and the second dose is given 4-5 hours before the colonoscopy.
- Primary Outcome Measures
Name Time Method Patient satisfaction with bowel prep Day 1,When arriving to the endoscopy unit, Immediately before the endoscopy When arriving to the endoscopy unit the patients fills in a questionnaire about their bowel-prep experience concerning; smell, taste, overall experience (five graded scales) of the prep. The higher the number are the more satisfied the patient are with the current experience (smell, taste and overall experience.
In the questionnaire they are also asked how much of the prescribed bowel-prep they have digested and how much extra fluid they have been drinking during the preparation process (0-4 litres).Efficacy of the bowel prep Day 1,Directly after the colonoscopy, Immediately after the colonoscopy the gastroenterologist who has performed the investigation fills in the Boston Bowel Preparation Scale,a widely used scale describing how clean the bowel is in each of the three segment ant in total. Each segment is graded form 0-3 (3 perfect cleaning) and a sum-score of 0-9 (9 perfect clening) is calculated. The higher the number the better the cleansing are
- Secondary Outcome Measures
Name Time Method Differences in the reported frequency of nausea and vomiting during the bowel-preparation process Day 1,When arriving to the endoscopy unit, Immediately before the endoscopy The patients are asked if they have been experienced nausea or been vomiting (yes /no)
