In most patients with high-grade dysplasia or early cancer in Barrett's esophagus, subtle lesions can be identified with high-resolution endoscopy. Indigo carmine chromoendoscopy and narrow-band imaging are comparable as adjuncts to high-resolution endoscopy.

Stepwise circumferential and focal ablation appears to be a safe and effective treatment for complete removal of Barrett's esophagus containing HGD, and can be safely performed after prior endoscopic resection for endoscopically visible abnormalities.

Stepwise radical ER is effective for selected patients with early neoplasia in BE; provides optimal histopathological diagnosis; and may reduce recurrence rate, since all mucosa at risk is effectively removed. Use of APC should be limited to prevent buried Barrett's mucosa. Methods for prevention of stenosis should be developed.
