What is the WATS3D Biopsy?

The WATS3D (Wide Area Transepithelial Sample with 3D Analysis) Biopsy provides a significant advance in the routine prevention of the most rapidly growing cancer in the US. WATS3D has been shown to be highly effective in quickly and easily increasing your detection of precancerous abnormality of the esophagus when used as adjunct to standard targeted forceps biopsy.

How does it work?

WATS3D® Biopsy addresses the sampling limitations of random forceps biopsies by obtaining a unique wide area tissue sample composed of three dimensional microbiopsies. Unlike cytology the WATS3D brush biopsy obtains a transepithelial specimen of the full-thickness esophageal mucosa for computer-assisted 3-dimensional analysis by specially trained GI pathologists.

How do I get started?

The WATS3D® brush biopsy instrument is passed through the operating channel of a standard endoscope and adds minimal time to the overall procedure. WATS3D Clinical specialists are available for training and physician support during procedures.

…four quadrant biopsies in Barrett’s esophagus leave significant unsampled mucosa. If dysplasia is missed, both the doctor and the patient have inaccurate information to guide care. WATS increases the likelihood of finding that potentially dangerous dysplasia, and does so quickly and with relatively low cost – something other techniques cannot offer.
Dr. Michael S. Smith, Medical Director, Esophageal Program, Temple University
Seeking dysplasia in a segment of Barrett’s esophagus is like looking for the proverbial needle in a haystack. Academic centers tend to perform numerous forceps biopsies on each of the high risk patients that they follow. The fact that the brush biopsy with computer-assisted tissue analysis was found to increase detection by over 40% in even these highly experienced esophageal GI specialty centers demonstrates the potential of this technique.
Sharmila Anandasabapathy, MD, Chief of Endoscopy at The Mount Sinai Medical Center
These two large studies demonstrating the same high degree of benefit from addition of the Brush Biopsy in two very different patient populations are extremely convincing. There is no reason not to include this test as part of every upper endoscopy with biopsy, and it will soon be available through all of our member hospitals and GI ambulatory surgery centers.
