WATS3D Biopsy Overview 2018-05-14T15:40:55+00:00


WATS3D Biopsy – A More Complete Biopsy

The WATS3D Biopsy is an adjunct to standard forceps biopsy of the esophagus which increases the tissue area sampled and therefore, increases the yield of patients identified with abnormality in the esophagus. The WATS3D biopsy device is passed through the operating channel of a standard endoscope. WATS3D is specifically designed to consistently sample deeper layers of the more firmly attached glandular epithelium found in Barrett’s esophagus.

WATS3D specimens are analyzed at CDx Diagnostics, where they are stained and examined by an advanced computer image three dimensional analysis system that was specifically designed to detect abnormalities including dysplasia and carcinoma. This is accomplished through detection of a combination of abnormal cellular morphology and molecular diagnostics. A pathologist with expertise in WATS biopsy analysis renders the final result following both computer-assisted and manual microscopic examination of the slide.

Why use WATS3D for every screening and surveillance biopsy:

Simply stated, the WATS3D Biopsy collects more tissue than any other biopsy used in the esophagus.
Even though the WATS3D biopsy is less invasive than a forceps biopsy, it is a full thickness biopsy; collecting tissue down to the lamina propria.
The proprietary 3-dimensional analysis allows every cell on the slide to be analyzed; making it easier to find more disease.


Collects More Tissue

The proprietary WATS3D instrument is designed to get a complete tissue biopsy down to the lamina propria. It’s linear design allows the endoscopist to sample more tissue, as well as a circumferential sample to be collected if necessary.


Analyzes More Cells

All of the over 100,000 harvested microbiopsies and individual cells on each WATS3D slide are analyzed by expert pathologists with the aid of a patented three dimensional neural network based imaging system.

Finds More Disease

Since the WATS3D instrument collects more tissue, and every cell on the slide is reviewed with computer assistance, the WATS3D computer-assisted biopsy is able to find more disease.
