A computer-assisted sampling system known as WATS3D that found crypt dysplasia in patients predicted a more aggressive form of Barrett's esophagus at rates the same or better than forceps biopsy, according to a study presented at the ACG Annual Scientific Meeting. Ten of the 380 patients with crypt dysplasia diagnosed through WATS3D progressed to high-grade dysplasia or esophageal adenocarcinoma, but none were caught using forceps biopsy, said Nicholas Shaheen, MD, FACG, of the University of North Carolina.
