Polyp of colon

This study tests whether adding a heat treatment (thermal ablation) to the standard procedure for removing large colon polyps can lower the chance they grow back. About 752 adults will be randomly assigned to receive either standard removal alone or standard removal plus burning …

This study tests whether spraying a mix of acetic acid and indigo carmine dye during colonoscopy helps doctors find more precancerous polyps (called sessile serrated lesions) in the right side of the colon compared to standard white-light colonoscopy. About 2,689 adults aged 45-8…

This study tests a new device that flattens colon polyps before they are examined under a microscope. The goal is to help doctors better identify sessile serrated lesions, a type of polyp that can lead to colorectal cancer. About 1,156 adults having polyps removed during a colono…

This study will check how well a non-invasive stool test (quantitative fecal immunochemical test, or qFIT) can detect colorectal cancer and precancerous lesions like adenomas and serrated polyps. Researchers will compare the test results with colonoscopy findings in 150 adults ag…

This study tests whether an artificial intelligence (AI) system can help doctors spot more precancerous polyps and colorectal cancers during colonoscopy compared to standard procedures. Over 3,300 adults scheduled for screening or surveillance will be randomly assigned to AI-assi…

This study tests whether spraying a protective medication (sucralfate) on the wound after removing colon polyps can prevent delayed bleeding better than the standard method of placing clips. The trial will include 160 patients who take blood thinners and have large polyps. Partic…

This early study tests a new device that supports the colon wall during polyp removal. It involves 4 people who have a positive stool test and a polyp on the left side of the colon. The main goal is to see if the device can be placed successfully in one try.

This study looks at people who have had certain types of colon polyps (serrated lesions) removed. It aims to find out why some of them later develop new advanced growths in the colon. By tracking 750 adults over time, researchers hope to identify risk factors that could help doct…

This study looks at how often polyps in the stomach or colon grow back after being removed during a scope procedure. Researchers will follow about 2,000 adults for up to three years to track recurrence and identify risk factors like polyp size, lifestyle, and health history. The …

This study looks at whether a special decision aid helps patients with a cancerous colon polyp choose between more surgery or careful monitoring. About 110 adults in Denmark will use the aid during their doctor visit. The goal is to see if it changes treatment choices and improve…

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 tests whether a computer-aided detection system can help doctors find more polyps in the right side of the colon during a colonoscopy. About 686 adults aged 40-75 will have two colonoscopies in one session, with the AI system used in one of them. The goal is to see if …

This study will look at 150 infants and children aged 1 month to 4 years who are admitted to a hospital gastroenterology unit with a gastrointestinal disease. The goal is to find out how common electrolyte disturbances (like low sodium or potassium) are in these children. By meas…
