Patterns of recurrent and persistent intestinal metaplasia after successful radiofrequency ablation of Barrett's esophagus.

Objective: Radiofrequency ablation can eradicate Barrett's esophagus successfully in the majority of cases. We sought to determine (1) how often intestinal metaplasia is detected during follow-up endoscopy after successful ablation and (2) patterns of persistent/recurrent intestinal metaplasia.

Methods: Patients ablated successfully during a phase II clinical trial of radiofrequency ablation for Barrett's esophagus were followed using endoscopic surveillance according to a defined protocol.

Effect of hiatal hernia size and columnar segment length on the success of radiofrequency ablation for Barrett's esophagus: a single-center, phase II clinical trial.

Objective: Hiatal hernia is common in patients with Barrett's esophagus. We sought to evaluate the effect of hiatal hernia size and initial columnar segment length on the success of radiofrequency ablation of Barrett's esophagus.

Methods: A phase II clinical trial was conducted aimed at evaluating the success of radiofrequency ablation in eradicating Barrett's esophagus.
