This study is observing patients who are already receiving radiofrequency ablation (RFA) for dysplastic Barrett's Esophagus (BE) or esophageal cancer. RFA is a treatment that uses heat to remove abnormal cells. Researchers want to understand how RFA changes the esophagus by measuring its 'distensibility' (how easily it stretches) and 'mucosal impedance' (how well the lining resists electrical current). This information could help predict how well RFA works and identify potential problems. You may be able to join if you are an adult with a confirmed diagnosis of BE with dysplasia or early-stage esophageal cancer, can take high-dose proton pump inhibitors (like omeprazole), and are willing to undergo multiple rounds of endoscopic treatment. This study is currently unclear on its recruitment status.

Study design

This is an observational study, meaning researchers will collect information during your regular treatment. It plans to include 10 participants.

What's involved

You would have measurements of your esophagus taken with two different devices during your clinically indicated upper endoscopies while you are receiving RFA treatments.

Compensation

Not stated in the trial record.

Follow-up

Measurements will be taken every 12 weeks, for up to one year.
