Improving clinical outcomes of Barrett's esophagus with high dose proton pump inhibitors and cryoablation.

INTRODUCTION: Esophageal adenocarcinoma incidence has increased significantly despite surveillance endoscopy for Barrett's esophagus (BE) and gastric acid supression medications. This prospective, cohort study's aims were to determine the long-term efficacy of proton-pump inhibitors twice daily (PPI-BID) with cryotherapy (CRYO) for complete ablation of BE.

MATERIALS AND METHODS: Consecutive BE patients were managed with a PPI-BID, CRYO ablation, follow-up protocol. Primary outcomes were to determine complete ablation rate of intestinal metaplasia (IM) or dysplasia/carcinoma, and factors affecting recurrence.

RESULTS: Sixty-two patients were enrolled: advanced disease (11%), low-grade or indefinite dysplasia (26%), non-dysplastic BE (63%). In 58 completing CRYO, eradication was confirmed in 100% on surveillance endoscopy. Adverse events (5%) were minor (mild pain 4%). IM recurred in 9% after a mean of 52 months, all successfully re-ablated. No second recurrence occurred. The primary predictor of recurrence was noncompliance with PPI-BID. BE or cardia IM recurred in 35% of those taking proton pump inhibitors once daily or less compared with 0% in those on PPI-BID or dexlansoprazole daily ( p <.001).

CONCLUSIONS: Minimizing acid reflux with at least PPI-BID combined with CRYO ablation appears to be the optimal cost-effective and safe BE treatment for any stage to minimize progression to adenocarcinoma by addressing both the stimulus that causes BE and the presence of goblet cells.
