AI-powered diagnostic platform to help prevent esophageal cancer.

Included in the Standard of Practice Guidelines for the screening and surveillance of Barrett’s esophagus, WATS3D is our proprietary diagnostic platform for identifying precancerous cells in the esophagus.

Technology

WATS3D empowers physicians to preempt cancer.

Changing the landscape of cancer prevention through innovative technology solutions.

Adjunctive use of WATS3D helps overcome sampling error that is inherent in the Seattle protocol

WATS3D provides physicians with a more effective endoscopic method of sampling tissue from the esophagus. It allows:

  • Sampling of much more at-risk mucosa, which reduces sampling error
  • Acquisition of deep mucosal tissue which is the location where pre-cancer (dysplasia) develops initially.


Limitations of the Seattle protocol:

  • 96% of the endoscopically suspect area remains completely unsampled
  • Significant sampling error and false negative results
  • Poor agreement rate among pathologists in diagnosing dysplasia
  • Time-consuming and labor intensive

"An estimated 33% of esophageal adenocarcinomas were diagnosed within 1 year of negative index endoscopy.”

— David A. Johnson, MD reviewing Visrodia K et al. Gastroenterology 2016 Mar

Clinical Data

WATS3D increased the overall detection of esophageal dysplasia by 242% and Barrett’s by 153%.

Adjunct use of our diagnostic platform has been vigorously tested for effectiveness in a clinical setting. Our largest study to date, involving more than 12,000 patients, yielded the results above. To put it simply: WATS3D has demonstrated reliable, consistent detection of more disease than standard biopsy methods alone.

Case Studies

Barrett's Esophagus and Low Grade Dysplasia Identified with WATS3D and Missed by Forceps Biopsy

68 year-old female with a chronic history of achalasia that had been treated with pneumatic dilation. Patient had been well managed for decades but developed persistent reflux symptoms. Forceps biopsy results were positive for Barrett’s metaplasia without dysplasia. WATS3D results demonstrated columnar epithelium with goblet cell metaplasia (Barrett's esophagus) with low-grade dysplasia involving the crypt.
