Polyp of large intestine

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 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 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 looks at whether telling people over 45 their genetic risk for colorectal cancer helps them decide to get their first colonoscopy. Researchers will track how many people schedule a colonoscopy after learning their risk, and compare findings like polyps between risk gro…

This study tests whether a two-week plant-based Mediterranean diet can change gut bacteria and reduce inflammation in people who have had colon polyps removed. Thirty participants will eat high-fiber meals delivered to their homes, and researchers will track changes in blood and …

This study looks at whether a blood test that detects tumor DNA can accurately identify patients who still have cancer after local removal of early-stage colorectal cancer. Currently, many patients undergo additional surgery even though about 85% are already cured by the initial …

This study is a registry that will review medical records of 1,000 patients treated for benign or malignant gastrointestinal diseases between 2005 and 2030. Researchers will look at survival, symptoms like heartburn and swallowing trouble, and quality of life. The goal is to lear…

This study looks at whether a computer-aided diagnosis (CADx) system can help doctors better identify small colorectal polyps (5 mm or smaller) during a colonoscopy. Over 360 doctors will use the system to predict whether polyps are harmless or precancerous. The goal is to see if…

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 …
