Polyp of colon

This study tests a vaccine that helps the body's immune system recognize and attack advanced colon polyps, which can turn into cancer. About 110 people who have had these polyps removed will receive either the vaccine or a placebo. The goal is to see if the vaccine boosts immune …

This trial asks whether a newer, simpler technique called cold snare polypectomy (CSP) causes less damage to blood vessels under colon polyps than the traditional hot snare method. It involves adults with non-cancerous colon polyps sized 10-19 mm. The study compares the presence …

This study is testing a robotic device that doctors use through the anus to remove benign growths (polyps, adenomas) from the rectum and sigmoid colon. The goal is to see if the device can remove the entire growth in one piece safely, without causing bleeding or a hole in the bow…

This study compares two methods for removing certain types of colon polyps (10-19mm adenomas or serrated lesions 10mm or larger) during a colonoscopy: cold snare piecemeal resection (CSPR) and cold snare endoscopic mucosal resection (Cold EMR). About 570 adults will take part to …

This study tests whether an artificial intelligence (AI) system can accurately identify the type of colon polyps during a colonoscopy, compared to standard visual inspection by the doctor. Over 1,700 adults having a colonoscopy will be randomly assigned to either AI-assisted or s…

This study tests a computer program that analyzes colonoscopy images to help doctors decide if a growth (polyp) is an adenoma (pre-cancerous) or not. The software gives a probability score for each lesion. The trial involves 1,178 adults and compares the software's results to lab…

This study tests a special probe that checks blood flow in ulcers left after colon polyp removal. The goal is to see if using this probe to guide treatment can prevent delayed bleeding, especially in patients taking blood thinners or with large polyps. About 180 high-risk adults …

This study tests a new device that takes detailed images of the lower gut during a standard colonoscopy. About 250 adults aged 45 to 75 will have the probe used during their procedure. The goal is to see if the device works well for real-time imaging.

This study looks at whether a 6-month or 12-month follow-up colonoscopy is better for people who had a large colon polyp (20-50 mm) removed that was not cancerous. About 546 adults will be assigned to one of the two follow-up schedules. The goal is to see which timing finds any r…

This study aimed to see if two advanced imaging modes, TXI and RDI, built into standard colonoscopy equipment, could make removing large colon polyps faster and safer. The trial was planned for adults with polyps 20 mm or larger, but it was withdrawn before any participants were …
