Filter by:This is a prospective multi-center randomized study is to determine whether the use of artificial intelligence (AI)-assistance could reduce the miss rates of polyps and adenomas in the proximal colon during tandem examination
A prospective validation of real time deep learning artificial intelligence model for detection of missed colonic polyps
Comparing the complete resection rate and subsequent adenoma recurrence rate at surveillance colonoscopy of 15-40mm laterally spreading adenomas for conventional EMR vs. cold snare EMR.
This is a single centre, non-randomized, tandem colonoscopy trial of the NISInspire-C System, followed immediately by a conventional colonoscope (CC). Each trial subject will undergo colonoscopy using the NISInspire-C system, followed immediately by CC. The purpose of this study is to obtain observational data on the safety profile, feasibility and usability of the NISInspire-C System in performing diagnostic colonoscopy in human subjects. The level of procedural pain experienced by subjects will also be explored.
61 subjects (male or female) between the ages of 45 and 75 will undergo colonoscopy. The primary outcome is Cecal Intubation
The main purpose of the study is to determine risk factors of poor bowel cleansing in patients referred for colon capsule endoscopy (CCE) examination. Patients will be prepared with polyethylene glycol (PEG), and a booster by using oral low volume sodium phosphate (NaP) and sodium-amidotrizoate and meglumine-amidotrizoate (Gastrografin ®) The investigators also will try to design a predictive score of poor bowel cleansing and to validate the Bowel cleansing score designed by Leighton and modified by Spada
The Efficacy and safety of Non-anesthesiologist administered propofol (NAAP) for gastrointestinal endoscopy have been widely documented although there is not information which has evaluated the outcomes of colonoscopy it self when the endoscopist has to fulfill the additional task of supervising the sedation. Objective: To determine the equivalence of adenoma detection rate (ADR) in colorectal cancer (CRC) screening colonoscopies performed with NAAP and performed with monitored anesthesia care (MAC). Method: Single blind non-randomized controlled equivalence trial. Patients: Adults between 50 - 69 years old from National CRC screening program (CRCSP). Intervention: The patients are blindly assigned to undergo either colonoscopy with NAAP or MAC according to the arrival of fecal occult blood test, patient's suitability for colonoscopy date and availability of places at endoscopy schedule (with NAAP or MAC).
This study is to evaluate the correlation of adenoma missing rate and quality indicators of colonoscopy including adenoma detection ratee (ADR), polyp detection rate (PDR), adenoma per colonoscopy rate (APC), adenoma per positive participant (APP), ADR-Plus, and to find out the surrogate indicators of ADR. This study is a prospective observational multi-center study. Correlation between AMR and quality indicators of colonoscopy based on the previous studies, 8 endoscopists participated in this study and will enroll 50 screening colonoscopies respectively. Recruit research participants who want to participate in research in outpatient clinics. Perform colonoscopy in the morning after colon cleansing with split method. Colonoscopy is performed by back-to-back two consecutive colonoscopies. When the first colonoscopy is performed, the colonoscope is retracted after inserting the cecum, and all colon polyps are removed. After retracting to the anus of the first colonoscopy, the second colonoscopy is performed immediately. In case of newly detected colon polyps except for the small polyps and S-colon and rectal polyps which were left as photographs during the first colonoscopy with the second colonoscopy, we regard them as an overlooked lesion during the first colonoscopy. After the procedure, the histologic examination is confirmed and classified as benign lesions (all adenomas, advanced adenomas, dysplasia, and colorectal cancer) and non-lesion lesions. Using the back-to-back colonoscopy results of the participants during the study period, calculate the quality indicators including ADR, PDR, APC, ADR-plus, APP and AMR for each endoscopist. And then, evaluate the correlation between AMR and other quality indicators.
The main purpose of the study is to determine risk factors of poor bowel cleansing in inpatients after a split-dose high volume preparation with 4 liters of polyethylene glycol. The quality of colon cleansing will be measured by the Boston bowel cleansing scale (more than or equal to 2 points in each segment). The secondary aim is to design a predictive score of poor bowel cleansing.
Colonoscopy is the gold-standard for the evaluation of the colorectal mucosa. Colonoscopy quality indicators are the adenoma detection rate, the rate of cecal intubation and the bowel preparation. The role of diet in preparing for colonoscopy is not fully established. Currently there is not enough evidence available to choice between 3 days of low residue diet versus 1 day. The research hypothesis is that the low residue diet offers a non-inferior bowel preparation and an improved tolerance.
