This study tests whether a computer-aided detection (CAD) system helps doctors find more polyps during screening colonoscopy, aiming to reduce the chance of advanced adenomas (precancerous growths) three years later. About 592 adults undergoing routine colonoscopy will be randoml…

This study tests whether a pre-packaged low-residue nutrition formula (Maifu Changqing®) can improve bowel cleanliness and comfort during colonoscopy preparation for 1,000 adults with inflammatory bowel disease (IBD). Participants will be randomly assigned to receive either the s…

This study looks at how much carbon dioxide is released during colonoscopy, a common test for colorectal cancer. Researchers will measure emissions from energy use, equipment, waste, and cleaning for 150 adults aged 18-80. The goal is to find ways to make this life-saving procedu…

This study involves 1,000 adults with inflammatory bowel disease (IBD) who need a colonoscopy. Researchers want to see how well current bowel preparation methods work and what factors lead to poor preparation. The goal is to create a tool that predicts which patients might have t…

This study compares two ways of explaining how to prepare for a colonoscopy: a standard oral explanation versus watching a video tutorial. About 574 adults having their first colonoscopy will take part. The goal is to see if the video leads to better bowel cleanliness and helps d…

This study is building a large database of colonoscopy reports and videos from about 1,800 people. The goal is to help train doctors, improve cancer prevention, and support research on new technologies. Participants simply undergo their planned colonoscopy, and their de-identifie…

This study looks at whether watching a video about how to prepare for a colonoscopy helps people do a better job than just getting written or spoken instructions. About 246 people who have never had a colonoscopy before will take part. The goal is to see if video education leads …

This study tests whether mixing an electrolyte beverage with water (instead of water alone) helps people drink the full bowel-cleansing solution before a colonoscopy. About 405 adults will be randomly assigned to one of three drink mixtures. The goal is to see if the electrolyte …

This study follows 8,000 adults in Denmark who are getting a screening colonoscopy for colorectal cancer. Researchers will ask about pain, discomfort, and overall experience right after the procedure. They will then check if those experiences influence whether people come back fo…

This study checks if using special clean water in reusable bottles for colonoscopies is safe. It looks for any contamination from the patient's own gut bacteria. The goal is to make the procedure more eco-friendly without risking patient safety. About 40 adults having a colonosco…
