WATS-3D Biopsy Increases Detection of Barrett’s Esophagus in GERD (MDedge)

A new study published in The American Journal of Gastroenterology shows that using WATS-3D, a wide-area transepithelial sampling tool with 3D computer-assisted analysis, alongside traditional forceps biopsies (FB) significantly increases detection of Barrett’s esophagus (BE) and dysplasia in patients with GERD undergoing screening endoscopy. In a registry of nearly 24,000 patients, WATS-3D identified BE in nearly 20% of cases missed by FB alone and doubled the detection of dysplasia. The tool also led to changes in clinical management in over 90% of cases with positive WATS-3D and negative FB results. Authors and experts suggest WATS-3D is a valuable adjunct to FB, potentially reducing missed diagnoses and repeat procedures.
