Diagnostic use of endoscopic mucosal resection.
We report two cases of gastric carcinoma where repeated, multiple conventional endoscopic biopsies were falsely negative. Endoscopic mucosal resection gave a positive diagnosis in both these patients. New equipment for aspiration mucosectomy makes the technique easier to perform, and a larger, deeper biopsy is obtained.
