Effectiveness of PLENVU in the General Screening Population and Patients With IBD

Overview

Patients presenting for endoscopic surveillance of IBD or colorectal screening colonoscopy at one of the participating centers will be asked to participate in the present study after careful evaluation of inclusion and exclusion criteria. The aim is that the final study population will comprise of 50% IBD patients and 50% colorectal cancer screening patients. Before inclusion, all patients have to sign the written informed consent. All participating patients will receive PLENVU, a well-known and approved bowel preparation agent. Bowel preparation is performed following the general recommendations of use. Following the bowel preparation, patients are asked if they have well tolerated the preparation, if they already had a colonoscopy in the past with another bowel preparation agent and if they would prefer PLENVU or another bowel preparation for their next endoscopy examination. Endoscopy is performed in standard way and effectiveness of the bowel preparation is specifically highlighted by the physician on the documentation report. Finally, data is analyzed regarding effectiveness of PLENVU for bowel preparation and patient satisfaction.

PLENVU is effective for bowel preparation and the efficacy and safety of PLENVU has been investigated in randomized controlled trials in patients undergoing gut cleansing prior to colonoscopy. Data on the specific screening population and for patients suffering from IBD however is limited to date. The aim of the current study is to fill this gap and to provide data of the effectiveness of PLENVU for the specific patients groups in order to provide specific recommendations for an adequate bowel preparation in those groups. In general, bowel-preparation in IBD patients is often more challenging. This might be due to the chronic disease burden but also according to compliance factors of individual patients. Of note, an adequate bowel-preparation is of paramount importance in IBD in order to detect subtle neoplasia and to perform chromoendoscopy, which is still recommended by the updated ESGE guideline. It is anticipated, that PLENVU will help IBD patients to achieve a better bowel preparation, thereby yielding in more effective screening colonoscopies and higher acceptance rates of patients for surveillance colonoscopies. In order to show that no significant differences are seen in the included IBD cohort compared to the general screening population (bias risk), the investigators aim to also include patients from the normal screening population.
