Polyp of colon

This trial tests whether completely closing the wound left after removing large flat colon polyps (at least 20 mm) reduces complications like delayed bleeding or perforation. About 686 adults scheduled for polyp removal will be randomly assigned to either have the wound closed wi…

This study tests whether adding a hot tool to the standard cold removal of large colon polyps lowers the chance of polyps growing back. About 194 adults with flat or slightly raised polyps at least 20 mm wide will be randomly assigned to one of two procedures. Participants will h…

Large colorectal polyps can turn into cancer, so doctors remove them during a colonoscopy. Even after removal, polyps often grow back. This trial compares two methods for sealing the area where the polyp was removed: one uses a water jet to lift tissue and then burns it with argo…

This study tests whether a laser-based device called AccuMeasure can measure the size of polyps and ulcers during gastrointestinal endoscopy more accurately than traditional methods like visual estimation or using tools as references. Researchers will compare AccuMeasure's readin…

This study aims to create a large library of recorded endoscopy procedures from adults undergoing upper or lower gastrointestinal exams. The goal is to use these videos to develop and validate artificial intelligence tools that can automatically detect and report quality metrics,…

This study is building a registry of adults undergoing advanced therapeutic endoscopy—minimally invasive procedures like EMR, ESD, and polypectomy—to treat conditions such as Zenker diverticulum, colon polyps, and colorectal cancer. The goal is to measure complication rates, comp…
