Polyp of large intestine

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 trial compares two endoscopic techniques for removing flat, non-cancerous colorectal polyps that are 10-20 mm in size. One method uses a cold snare (no heat), while the other uses a hot snare with electrocautery. The goal is to see if the cold approach is just as effective a…

This trial tests whether an AI system called GI Genius can help doctors accurately tell apart small colorectal polyps (5 mm or less) during a colonoscopy—identifying which ones are harmless versus those that need monitoring. For each small polyp, doctors first record their own di…

This study compares a new 3D colonoscopy with the standard 2D version to see which more accurately identifies polyps that could become colorectal cancer. About 600 adults undergoing colonoscopy will have their polyps examined with both methods, and the results will be checked aga…

This study looks at whether people who have had large colon polyps removed can safely wait longer for their next colonoscopy. About 760 adults will be split into two groups: one getting the standard schedule (colonoscopy at 6, 18, and 48 months) and another getting a relaxed sche…

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 study tests whether letting patients give themselves sedation medication (propofol) by pressing a button during a colonoscopy leads to higher satisfaction than standard sedation given by a doctor. About 40 adults scheduled for colonoscopy will be randomly assigned to either …

This study tests whether a special imaging mode called RDI helps doctors remove early-stage cancers from the stomach, esophagus, or colon more quickly and safely than standard white-light endoscopy. About 158 adults with early cancers or precancerous lesions will be randomly assi…

This study looks at whether showing AI suggestions a few seconds later helps doctors make better decisions when diagnosing small colon polyps. Seventy endoscopists will watch 100 polyp videos, with some seeing AI advice right away and others seeing it after a delay. The goal is t…

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 whether an artificial intelligence (AI) system can help doctors in general hospitals accurately decide how to manage small colon polyps (5mm or smaller) during a colonoscopy. About 363 adults with at least one small polyp will be randomly assigned to have their p…
