Polyp of colon

This study compares two methods for finding precancerous colon polyps during colonoscopy. Both methods use water instead of air to inflate the colon and an AI system to spot polyps. One group also uses a special light filter called linked-color imaging. The goal is to see if the …

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…

This study follows 404 people who previously had either an AI-assisted or conventional colonoscopy. Researchers want to see if AI help lowers the risk of developing advanced colon polyps later. Participants will undergo a surveillance colonoscopy to check for new growths.

This study is testing a new capsule camera (CapsoCam Colon) that you swallow to detect colon polyps. About 330 adults aged 45-75 will swallow the capsule and then have a standard colonoscopy for comparison. The goal is to see if the capsule, with AI help, can accurately find poly…

This study tests an AI tool called EndoAIM that helps doctors measure the size of polyps found during a colonoscopy. Accurate size measurement is important because larger polyps (over 10 mm) have a higher risk of becoming cancer. The study will enroll 278 adults undergoing colono…

This study compares AI-assisted colonoscopy to conventional colonoscopy in 915 adults aged 50 and older. The goal is to see if AI helps doctors detect more polyps and better classify them as benign or malignant. Researchers will also compare costs between the two methods.

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 trial tests whether a walking program can reduce signs of colorectal cancer in men who had pelvic radiation for prostate cancer. Radiation can raise the risk of colon cancer years later by causing mutations and inflammation. Researchers will compare colon tissue and blood sa…

Researchers are testing whether a compression belt worn around the lower abdomen, combined with water exchange colonoscopy, can lower how often endoscopy staff must press on a patient's belly during the procedure. The trial enrolls 400 adults aged 45 to 80 at average risk for col…

This study compares two sedative drugs, remimazolam and propofol, in 90 adults having colonoscopy to remove polyps. The goal is to see which drug keeps the heart and breathing more stable during the procedure. Results may help choose safer sedation for routine colonoscopies.

This study tests whether a high-flow nasal cannula (HFNC) can prevent dangerous drops in oxygen levels during sedated gastrointestinal endoscopy in critically ill patients. Researchers will compare HFNC with standard nasal oxygen in 450 adults with serious health conditions. The …

This study looks at whether using lower pressure gas during laparoscopic large bowel surgery can protect the gut and help patients recover faster. About 125 adults having certain types of colon surgery will be randomly assigned to different pressure levels. The goal is to see if …

This study tests whether a technique called cold snare polypectomy can safely remove 10-20 mm colon polyps without using heat. About 120 adults will have their polyps removed this way during a colonoscopy. The goal is to see if it works well and causes fewer complications than tr…

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 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…

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 tests a simple web-based tool that helps doctors predict whether a large colon polyp contains invasive cancer. The tool uses only standard endoscopic images and basic information like polyp size and location. Doctors of varying experience will use the tool to assess po…

This study follows 3,500 adults with large colon polyps (20 mm or bigger) to see how well current removal methods work. Doctors will record details about the patients, polyps, and procedures. The goal is to learn what leads to successful removal without surgery and to track any c…

This study is testing whether an artificial intelligence system called GI Genius can help doctors find more polyps during colonoscopy. Polyps are growths that can sometimes turn into cancer. The study will include about 764 adults having a colonoscopy at a hospital in Singapore. …

This study tests whether using a patient's existing CT scan to guide the colonoscope can make the procedure faster, less painful, and easier for doctors. About 200 adults getting a colonoscopy will be randomly assigned to standard or CT-assisted insertion. The goal is to see if t…

This study is testing a new device that uses small electric pulses to destroy colon polyps during a colonoscopy. Researchers want to see if it is safe and effective for removing polyps. Thirty adults with at least one polyp larger than 5mm in the lower colon will be enrolled. The…

This study collects high-quality videos from routine colonoscopy screenings to help test and improve an automatic polyp detection device. About 700 adults undergoing standard colonoscopy will have their procedure recorded. The goal is to gather enough good footage to evaluate how…
