Poster 1823 Assessment of Sponge-on-String Device Parameters for the Non-endoscopic Detection of Barrett’s esophagus: Results from a Randomized Trial

Author Insight from Prasad G. Iyer, MD, MSc, FACG, Mayo Clinic

What’s new here and important for clinicians?

This abstract details our efforts to develop a minimally invasive method of screening for Barrett’s esophagus (BE) using a capsule sponge combined with novel methylated DNA markers. In this randomized controlled trial, we compared the tolerability and safety of two types of sponges (a 25 mm/10 pores per inch versus a 25 mm/20 pores per inch) in patients with and without BE. The capsules were successfully swallowed by 98% of participants. Patient tolerability was better with the 25/10 pores-per-inch sponge. Additionally, the capsule sponge did not cause any significant trauma in the esophagus and was safe.

Finally a two DNA methylated marker panel was able to accurately classify the presence or absence of BE with 100% accuracy, making this a promising test for BE screening.

What do patients need to know?

This is a potentially exciting screening tool for Barrett’s esophagus and esophageal cancer.
