Polyp of colon

This early-stage trial is testing whether a pill made from freeze-dried healthy donor stool (MTP-101P) is safe and can restore good bacteria in people having part of their colon removed. Forty adults aged 18-75 with colon polyps, early-stage cancer, or diverticulitis will take th…

This study is testing a new surgical stapler, called the Signia circular stapler, in people having left-sided colon, sigmoid, or rectal surgery. The goal is to see if it lowers the chance of a leak where the colon is reconnected. About 137 adults will take part, and the main focu…

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 tests a new device called EndoTEM, which helps doctors use two instruments at once to remove large polyps from the lower colon. The goal is to see if it is safe and can remove the entire polyp in one piece. Thirty adults with large polyps or early cancer in the rectum …

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 compares two methods used during colonoscopy to remove large, flat colon polyps: marking the edges before removal or using heat to treat the edges after removal. The goal is to see which method better prevents polyps from growing back. About 342 adults with polyps 20 m…

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 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 is testing a new blood test called DENEB that looks for tiny molecules (microRNAs) to find colorectal cancer and precancerous polyps early. Researchers will collect blood samples from 2,000 people who are also getting a colonoscopy. The goal is to see if the blood test…

This study is testing whether a real-time artificial intelligence system can help doctors find more sessile serrated lesions (a type of precancerous polyp) during colonoscopy. About 628 adults aged 40-80 will be randomly assigned to have a colonoscopy with or without the AI aid. …

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 is testing a blood test (called a liquid biopsy) to see if it can find colorectal cancer, pre-cancerous growths (adenomas), and cancers linked to Lynch syndrome at an early stage. Researchers will enroll 1,200 people who have already had a colonoscopy. The goal is to s…

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.

This study tests a new microwave-based device, called MiWEndo, that is used during a standard colonoscopy to help doctors find polyps in the colon. About 50 people who already have a polyp in their rectum will take part. The goal is to see if the device is safe and can find more …

This study looks at whether people who have had 1 or 2 small, non-cancerous polyps removed can safely wait 10 years for their next colonoscopy instead of the usual 5 years. About 9,500 adults aged 45-69 will be randomly assigned to one of two schedules: a colonoscopy at 5 and 10 …

This early-phase study tests the safety of a drug called ONC201 (dordaviprone) in 36 adults at high risk for colorectal cancer due to familial adenomatous polyposis (FAP) or a history of many polyps. The drug aims to kill precancerous cells without harming normal ones. Researcher…

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 aims to collect medical data and biological samples (blood, urine, stool, and tissue) from up to 4,000 adults with known or suspected gastrointestinal diseases. Participants receive standard medical care at the NIH, and any extra samples or leftover tissue from procedu…

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…
