Gross 1 , Lauren Gerson2 , Blair Lewis 3 , Robert A. Ganz 4 , 1 NYU Langone Medical Center, New York, NY, 2 California Pacific Medical Center, San Francisco, CA, 3 Mount Sinai School of Medicine, New York, NY, 4 Minnesota Gastroenterology, PA  \nINTRODUCTION  \nPoor bowel preparation affects the completeness of the colonoscopy and can result in longer procedural times, missed adenomas, earlier repeat procedures, increased costs, and decreased patient satisfaction.  \nThe MOTUS GI Pure-Vu ™ System (Tirat Carmel, Israel) has been designed to improve visualization in an inadequately prepared colon by facilitating intra-procedural cleaning. The primary aim was to rate adequate colon cleansing level as defined by a Boston Bowel Prep Score (BBPS), at baseline and after the use of Pure-Vu.The secondary endpoints were Pure-Vu usability via questionnaire and safety evaluation.  \nMETHODS  \nPure-Vu System  \nThe system consists of a disposable single-use over-sleeve and a workstation controller. The disposable over-sleeve fits easily over standard colonoscopes without interfering with the working channel or the navigation or advancement of the colonoscope. The workstation controls the delivery of a novel irrigation mode via 4 jets and a regulated evacuation cycle that effectively removes considerable colon content and prevents potential clogging through an auto-purge function.  \nPure-Vu Work Station Controller Pure-Vu Disposable on Colonoscope  \nPure-Vu Disposable Distal End – Irrigation Mode  \nSTUDY DESIGN  \nThe Pure-Vu system was used in 35 procedures in swine (66% female) performed by 4 experienced gastroenterologists. In order to ensure an inadequate bowel preparation, the animals underwent a reduced preparation. Immediately after the procedure, physicians graded the cleanliness of the colon at baseline and after use of Pure-Vu as one segment using the Boston Bowel Prep Score and completed a questionnaire on the Pure-Vu usability. Following their colonoscopy, the animals were observed for 48 hours to ensure their full recovery and document any post-procedural adverse events.  \nEvaluation of Cleansing Level  \nEvaluation of Pure-Vu Usability  \nThe usability of the Pure-Vu system was done via a questionnaire after each procedure. Physicians were requested to grade the Pure-Vu usability on a 5 point scale where 1 was considered unacceptable and 5 as excellent.  \nThe questionnaire included the following evaluation criteria:  \n1. General Ease of Use 6. Device Stiffness  \n2. Ease of Insertion into Rectum 7. Device Holding Force (weight, comfort)  \n3. Ease of Angulation (steering capability) 8. Ease of Use Foot Pedals  \n4. Torque Response 9. Ease of Use Foot Buttons  \n5. Ease of Advancement 10. Safety Evaluation  \nEvaluation of Safety  \nAdverse events were evaluated during and post-procedure for 48 hours. Any adverse events during the procedure were recorded per physician discretion. Following the procedure, the animals were observed for 48 hours to assess the effect of the procedure on their health.  \nRESULTS  \nCleansing Performance  \nThe average BBPS score prior to the use of Pure-Vu was 0.5 with 86% of the animals being inadequately prepped (BBPS score \u003C2) and the majority (60%) having a score of zero. Following the use of Pure-Vu 100%(35/35) of the animals had a BBPS score = 3 (i.e. , Excellent) .  \nFigure 1. below shows the distribution of BBPS scoring at baseline and after the use of the Pure-Vu. The level of adequate bowel prep at baseline and after Pure-Vu use is shown in Figure 2.  \n14%  \nExcellent (BBPS=3) Good (BBPS=2) Fair (BBPS=1) Poor (BBPS=0)  \nThe images below are representative of colon cleansing levels at baseline and after Pure-Vu use.  \nBEFORE  \nBaseline 15P0862 Baseline 15P0845 Baseline 15P0877 Baseline 15P0719  \nAFTER  \nAfter Pure-Vu Use 15P0862 After Pure-Vu Use 15P0845 After Pure-Vu Use 15P0877 After Pure-Vu Use 15P0719  \nPure-Vu Usabil","cbCaij8EHyMJcYgZ","https://ap.wps.com/l/cbCaij8EHyMJcYgZ","pdf",3820513,"English","# Introduction\n# Methods\n## Pure-Vu System\n## Study Design\n# Evaluation\n## Cleansing Level\n## Pure-Vu Usability\n## Safety Evaluation\n# Results\n## Cleansing Performance\n## Pure-Vu Usability\n## Safety\n# Summary & Conclusions","[{\"question\":\"What problem does the study address in colonoscopy?\",\"answer\":\"Inadequate bowel preparation reduces visualization, leading to incomplete procedures, missed adenomas, longer procedural times, and lower patient satisfaction.\"},{\"question\":\"How was the MOTUS GI Pure-Vu system evaluated?\",\"answer\":\"The system was tested in 35 swine procedures using Boston Bowel Prep Score (BBPS) before and after Pure-Vu, followed by a usability questionnaire and 48-hour safety monitoring.\"},{\"question\":\"What were the study results regarding effectiveness and safety?\",\"answer\":\"After Pure-Vu use, 100% of animals achieved BBPS = 3 (Excellent).
