Trial Summary

Do I need to stop my current medications for the trial?

The trial requires that you stop taking anti-platelet medications, anti-coagulation medications, and NSAIDs (non-steroidal anti-inflammatory drugs) before the procedure.

How does the OFDI Capsule Imaging treatment for Barrett's Esophagus differ from other treatments?

The OFDI Capsule Imaging treatment is unique because it uses a capsule with advanced imaging technology to non-invasively detect Barrett's Esophagus, unlike traditional methods that require endoscopy with sedation. This capsule captures high-resolution images at a fast rate, allowing for detailed examination of the esophagus without the need for invasive procedures. ^{1 2 3 4 5}

What is the purpose of this trial?

The purpose of this research is to test the feasibility, sensitivity, and specificity of the marking Optical Frequency Domain Imaging (OFDI) capsule for diagnosing Barrett's Esophagus (BE).

Eligibility Criteria

This trial is for adults over 18 who can consent to participate and are scheduled for an EGD, a type of esophagus examination. It's not suitable for those with narrowings (strictures) in the esophagus, bleeding disorders, or those taking certain blood-thinning medications including NSAIDs.

I am scheduled for an upper GI endoscopy.

Patients must be able to give informed consent

Exclusion Criteria

I have a narrowing in my esophagus.

I am taking blood thinners or NSAIDs currently.

I have a history of bleeding or clotting disorders.

Treatment Details

Interventions

• OFDI Capsule Marking

Trial Overview The study is evaluating a new capsule-based technology called OFDI Capsule Marking to diagnose Barrett's Esophagus. This involves swallowing a capsule that captures detailed images of the esophagus lining during an EGD procedure.

Participant Groups

Group I: OFDI Capsule Marking and Imaging Experimental Treatment 1 Intervention

Subject will swallow the OFDI capsule, marking will be performed by making superficial cautery marks on the tissue. This will be followed by imaging using the OFDI Imaging system.

Findings from Research

The study successfully demonstrated that laser marking of targeted esophageal sites identified through optical frequency domain imaging (OFDI) is highly accurate, with a success rate of 97.07% in marking the correct locations in an experimental study involving 5 swine.

All laser marks were clearly visible during endoscopy, and the thermal damage caused by the laser was limited to superficial mucosal layers, showing signs of partial healing within 2 days, indicating a safe approach for guiding biopsies.

Image-guided biopsy in the esophagus through comprehensive optical frequency domain imaging and laser marking: a study in living swine. Suter, MJ., Jillella, PA., Vakoc, BJ., et al.[2022]

Optical frequency domain imaging (OFDI) offers a high-resolution imaging technique (about 10μm) that can improve the diagnostic accuracy for Barrett's esophagus (BE) compared to standard endoscopy, which has limitations in accuracy and is costly due to sedation requirements.

When used with a balloon-centering catheter, OFDI allows for comprehensive imaging of the entire distal esophagus, potentially enhancing early detection of dysplastic changes that could lead to esophageal adenocarcinoma.

Recent advancements in endoscopic imaging technologies have significantly improved the detection of dysplasia and early cancer in Barrett's esophagus, emphasizing the need for high sensitivity and specificity in these techniques.

Novel imaging modalities like chromoendoscopy, autofluorescence imaging, and narrow band imaging are now being used in routine practice, allowing gastroenterologists to effectively target abnormal areas during examinations.
