Interventional, Prospective, Self Control
Conditions
Brief summary
To verify the correlation between the proposed artificial intelligence based bowel preparation assessment system and the missed detection rate of adenomas, and to evaluate whether the system can effectively assist doctors in identifying patients who need to be re-examined by colonoscopy due to poor intestinal cleanliness.
Interventions
DIAGNOSTIC_TESTBowel readiness
During the examination, the endoscopic physician required to stay in place while rinsing, and the lens could only be withdrawn after rinsing. During the examination, the recorder should record the time points of the right colon, transverse colon, and left colon, as well as the time of irrigation. If both are considered to be properly, then second colonoscopy was performed immediately. If both results agree or either side agrees that the gut is not well prepared, the review will be carried out within a year

Subjects who meet any of the following specific criteria will be refused to participate in the study: 1. have a history of drug or alcohol abuse or psychological disorders within the last 5 years; 2. Pregnant or lactating women; 3. Patients with known multiple polyp syndrome; 4. patients with known inflammatory bowel disease; 5. known intestinal stenosis or space-occupying tumor; 6. known colon obstruction or perforation; 7. patients with a history of colorectal surgery; 8. Patients with previous history of allergy to pre-used spasmolysis; 9. Unable to perform biopsy and polyp removal due to coagulation disorders or oral anticoagulants; 10. High risk diseases or other special conditions that the investigator considers the subject unsuitable for participation in the clinical trial.

| Measure | Time frame | Description |
|---|---|---|
| Missed detection rate of ≥5mm adenoma | 6 months | (≥ 5mm adenoma missed rate, ≥ 5mm AMR) : Each patient will receive two colonoscopy examinations. The ≥ 5mm adenoma that were not detected in the first colonoscopy was define as missed ≥ 5mm adenoma. Numerator is the number of missed detection of ≥5mm adenomas during colonoscopy, and denominator is the total number of ≥ 5mm adenomas receiving colonoscopy. |
