Follow-up of Barrett's epithelium after ablation by endoscopic argon plasma coagulation.

We read with interest the article by Schultz et al.1 on ablation of nondysplastic Barrett's epithelium by endoscopic argon plasma coagulation in combination with high-dose omeprazole. Using APC and acid suppression with 120 mg/day of omeprazole, they obtained complete ablation of Barrett's epithelium in all but 1 of their 70 patients and, adapting the acid suppression to obtain cumulative reflex time of less than 7% per 24 hours, they did not observe relapse of Barrett's epithelium after a median follow-up of 12 months.
