What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers at Fudan University are testing whether an artificial intelligence tool can score bowel preparation quality by measuring fecal coverage during colonoscopy. The study enrolls 560 adults aged 45 to 75 who have not had a colonoscopy in the past three years. The goal is to see if this AI-based score correlates with the adenoma detection rate, which is the proportion of patients in whom precancerous polyps are found. If the score works well, it could help doctors assess bowel cleanliness more consistently and potentially improve the detection of polyps during screening.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If the AI score reliably predicts adenoma detection, it could help doctors assess bowel preparation quality more objectively and improve colonoscopy outcomes.
What could go wrong
This is an observational study, so it cannot prove cause and effect. The AI score may not correlate strongly with adenoma detection in all patients.

Inclusion Criteria: * aged 45-75 years * No colonoscopy within the past 3 years Exclusion Criteria: * Patients scheduled for therapeutic colonoscopy, postoperative surveillance after colorectal surgery, or treatment of histologically confirmed polyps * Patients with highly suspected or pathologically confirmed colorectal cancer * Patients presenting with alarm symptoms or signs (hematochezia, melena, unexplained anemia or weight loss, palpable abdominal mass, or a positive digital rectal examination) * Pregnant or breastfeeding women * Patients with gastrointestinal obstruction * Patients with inflammatory bowel disease, familial adenomatous polyposis, or serrated polyposis syndrome * Patients who have taken anticoagulants (e.g., aspirin, warfarin) within 7 days before colonoscopy or who have coagulation disorders * Failed cecal intubation due to any cause other than excessive feces preventing intubation (e.g., obstructive lesions preventing scope passage, or patient intolerance to the procedure). * Use of non-guideline-recommended bowel preparation agents * Patients undergoing emergency colonoscopy
