Recruiting studies
- NCT06041945Recruiting
AI study for cheaper colon cancer screening
This study uses artificial intelligence to help doctors predict if colon polyps are harmless during a colonoscopy. This could reduce the need for lab tests and save costs.
Rozzano, MilanoAges 40 years+ - NCT07420309Recruiting
Colonoscopy training with or without AI assistance for residents
This trial tests whether using artificial intelligence (AI) during colonoscopy training helps endoscopy trainees find polyps better. It involves adult patients getting a colonoscopy for screening, diagnosis, or follow-up.
LarissaAges Any age - NCT07335705Recruiting
Factors affecting bowel prep in IBD patients
This study looks at factors that affect how well the bowel is cleaned before a colonoscopy in people with IBD. The goal is to improve preparation so the colonoscopy can be more effective.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07299071Recruiting
Computer-assisted detection to reduce advanced polyps at three-year follow-up
This trial tests whether a computer-aided detection (CAD) system helps doctors find more advanced polyps during screening colonoscopies, potentially reducing the risk of these polyps turning into cancer over three years. If you are undergoing a screening colonoscopy, this study may help improve early detection and prevention.
BayonneAges 18 years+ - NCT07060222RecruitingPhase 4
Comparing two bowel preps for colonoscopy: lactulose vs sodium phosphate
This study tests whether lactulose or sodium phosphate is better for cleaning the bowel before a colonoscopy. If you need a scheduled colonoscopy, this trial might help find which preparation works best.
Guadalajara, JaliscoAges 18 years+ - NCT06333392Recruiting
Underwater colonoscopy for better cancer screening
This trial tests if a new type of colonoscopy called total underwater colonoscopy (TUC) is better at finding polyps and cancer during routine screening. If you had a positive FIT stool test and are scheduled for a follow-up colonoscopy, you may be able to join.
DrammenAges 55–60 - NCT07699809Recruiting
Thirst relief kit for thirst after colonoscopy prep
This trial tests whether a 'thirst relief kit' can help reduce thirst after the bowel preparation for a colonoscopy. If you are having a colonoscopy with hospital-based bowel preparation, you may be eligible to receive the kit or a placebo (a kit without active ingredients) to see if it helps with thirst.
São Paulo, São PauloAges 18 years+ - NCT07355777Recruiting
Video tutorial for first colonoscopy preparation
This trial tests whether adding a short video tutorial to the usual verbal instructions helps people prepare better for their first colonoscopy. It aims to see if the video makes the preparation process easier and more effective.
LyonAges 18–80 - NCT06878378Recruiting
Why some people have poor colonoscopy prep
This study looks at what factors might make it harder to clean out your bowel before a colonoscopy. Understanding these reasons could help doctors give better instructions and improve success rates.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06924489Recruiting
3D imaging for better adenoma detection during colonoscopy
This trial tests a 3D imaging device during colonoscopy to see if it helps find more advanced adenomas (precancerous polyps) than standard colonoscopy. If you are scheduled for a diagnostic colonoscopy and haven't had colorectal cancer or polyps removed before, this study might be for you.
Xi'an, ShaanxiAges 18–75 - NCT06692673RecruitingPhase 1/Phase 2
Linaclotide for Colonoscopy Bowel Preparation
This trial tests if a medication called linaclotide (a pill that helps with constipation) can improve the bowel-cleaning process before a colonoscopy. It may make the preparation easier and more effective.
Gainesville, FloridaAges 18–65 - NCT06678477Recruiting
Comparing 3D vs. standard colonoscopy after positive stool test
This study compares a new 3D colonoscopy with the standard colonoscopy to see which one finds polyps better in people who had a positive stool test (FIT). If you're 40 or older and had a positive FIT, this trial may help improve how colorectal cancer is detected.
HsinchuAges 40 years+ - NCT05080673Recruiting
Colonoscopy planning for small, noncancerous colon polyps
This trial tests whether people with 1–2 small, noncancerous colon polyps should get their next colonoscopy after 5 years or after 10 years. It may help reduce unnecessary procedures or find cancers earlier if the shorter interval is safer for you.
Fairbanks, AlaskaAges 45–70 - NCT03363061Recruiting
People taking blood thinners having colonoscopy
This study looks at patients who are already taking blood-thinning medicines and are scheduled for a planned colonoscopy. It may help improve how colonoscopies are done safely for people on these medicines.
Hong KongAges 18 years+ - NCT07853300Enrolling by invitation
Virtual reality for comfort during colonoscopy
This study tests whether using virtual reality (a computer-generated 3D environment you can see and hear) during a colonoscopy can reduce pain, anxiety, and embarrassment. If it works, it could make the procedure more comfortable for people who have it without sedation.
Kocaeli, İzmitAges 18–65 - NCT07812155Recruiting
AI-assisted bowel prep for colonoscopy
This trial tests whether an AI-assisted app can help hospitalized patients prepare better for a colonoscopy. It may make the bowel-cleansing process easier and more effective.
Chiayi City, TaiwanAges 20 years+ - NCT07658716Recruiting
Colonoscopy surveillance recommendation study
This study tests a tool to help doctors make better recommendations for colonoscopy follow-up. It may improve how often patients get the right screening.
New York, New YorkAges 18 years+ - NCT07608120Recruiting
Electrolyte drink with bowel cleansing solution for colonoscopy prep
This study tests whether combining an electrolyte beverage (a drink with salts and minerals) with polyethylene glycol—a standard bowel-cleaning solution—helps prepare your colon better for colonoscopy. The goal is to see if this combination makes the preparation easier to tolerate while still cleaning your bowel effectively.
Guangzhou, GuangdongAges 18–75 - NCT07588386Recruiting
Early Colonoscopy After Low Rectal Cancer Surgery
This study tests whether doing a colonoscopy (camera exam of the colon) early after surgery for low rectal cancer helps catch a serious complication called anastomotic leakage—when the surgical connection between bowel segments breaks down. Early detection might help prevent severe infections and improve outcomes.
Nanchong, SichuanAges 18–80 - NCT07557173Recruiting
Better Bowel Prep for Repeat Colonoscopy After Failed Cleaning
This trial tests three different bowel-cleaning preparations for patients who need a repeat colonoscopy because their bowel wasn't clean enough the first time. The goal is to find which preparation works best to get your colon ready for a successful second procedure.
BeneventoAges 18 years+ - NCT07541924Recruiting
Image-Guided Colonoscopy: Patient Experience and Doctor Efficiency
This study tests whether using CT scan images to guide doctors during colonoscopy (a camera exam of your colon) improves how well the procedure goes and reduces doctor stress. You'll answer questions about your experience before and after the procedure.
Beijing, Beijing MunicipalityAges 18–80 - NCT07520578RecruitingPhase 3
Doctor Support to Complete Colon Screening After Positive Test
This study tests whether early information and encouragement from your primary care doctor helps you complete a follow-up colonoscopy after an abnormal screening test for colorectal cancer. The goal is to reduce delays and ensure people get the care they need quickly.
Tours, FranceAges 50–75 - NCT06786793Recruiting
AI in colonoscopy screening study
This study tests whether artificial intelligence can help doctors find polyps or other issues during a colonoscopy. It may lead to better detection and earlier treatment.
Krakow, Lesser PoladnAges 50–65 - NCT07467928Recruiting
AI colonoscopy's long-term effect on advanced polyps
This study looks at how well AI-assisted colonoscopy prevents new advanced polyps from forming over the long term. It's for people who were in our earlier AI colonoscopy study and are healthy enough for a follow-up scope.

Common questions
- Are there clinical trials for colonoscopy?
- Yes. Clin2 currently lists 115 recruiting colonoscopy studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a colonoscopy trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a colonoscopy trial?
