Intervention / Treatment |
---|---|
Experimental: Optical coherence tomography (OCT) probe
After consent, the endoscopist will perform a standard of care colonoscopy.
If a polyp is found, then OCT will be used to image that polyp.
Patients with polyps, regardless of number found, will have either one tubular adenoma (NICE type 2) imaged OR one hyperplastic polyp (NICE type 1) imaged.
If no polyps are found, then one area of normal mucosa will be imaged.
If on the rare chance a malignant appearing colonic tumor (NICE type 3) is found, this and no other polyps will be imaged with OCT.
|
The OCT probe is attached to an approximately 3-meter wire that is attached to the OCT fiber probe system setup.
This setup consists of a power supply unit, and a control platform that controls fiber probe rotation and retraction.
The OCT probe will be advanced through the colonoscope instrument channel

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Proportion of Participants Whose Procedure Length Using an OCT Probe During Routine Colonoscopy is Within 5 Minutes
Time Frame: Within 5 minutes during standard of care colonoscopy - Day 1 (average length 3:40 minutes (full range 1:54-8:20 minutes)
|
If the proportion of the patients whose procedure length using an OCT probe during routine colonoscopy is within 5 minutes is greater than 75%, then the feasibility is defined in this study.
|
Within 5 minutes during standard of care colonoscopy - Day 1 (average length 3:40 minutes (full range 1:54-8:20 minutes)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Adverse Events Related to OCT Imaging During Routine Colonoscopy
Time Frame: From start of colonoscopy through 48 hours after colonoscopy (estimated time of 3 days)
|
The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 will be utilized for all toxicity reporting.
|
From start of colonoscopy through 48 hours after colonoscopy (estimated time of 3 days)
|
Number of Participants Who Have a Successfully Captured OCT Image Using Machine Learning Algorithm
Time Frame: During colonoscopy (Day 1)
|
Whether OCT image is successfully captured using machine learning algorithm, coded as "good" or "noisy".
|
During colonoscopy (Day 1)
|
Cohen's Weighted Kappa Score
Time Frame: During colonoscopy (Day 1)
|
Overall agreement (OCT probe yielding results consistent with clinical pathology biopsy results) as measured by Cohen's Kappa. Overall Cohen's Kappa is a statistical measure for assessing the reliability of agreement between the two results by taking into account the element of chance. Cohen's kappa can range from 0 to 1 with 1 indicating perfect agreement and 0 indicating an agreement equivalent to chance. Clinical pathology is the gold standard for diagnosis. Diagnosis from both OCT and clinical pathology will be assigned as normal mucosa, hyperplastic polyp, tubular adenoma, sessile serrated adenoma, or colorectal cancer. |
