Core Tip
Core tip: The current standard of care in treatment of dysplastic Barrett’s esophagus is endoscopic ablation. Cryospray ablation, the newest modality can achieve complete eradication of dysplasia and intestinal metaplasia in over 90% of patients. Unlike other endoscopic methods, its unique mechanisms and depth of injury enable successful ablation of early esophageal carcinoma, palliative debulking of advanced carcinoma and reduction of tumor ingrowth into stents. The applications of cryospray ablation beyond the esophagus include control of bleeding from gastric antral vascular ectasia, portal hypertensive gastropathy, and radiation proctitis. This modality continues to evolve as an important tool of therapeutic endoscopy.
