Brief Summary:
To assess the response of persistent Barrett's Esophagus and/or dysplasia to focal cyro ablation .

Condition or disease Intervention/treatment Phase
Barrett's Esophagus Device: CryoBalloon Focal Ablation Phase 4

Detailed Description:
Observational study of patients undergoing clinically indicated focal cryo ablation

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 10 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: CryoBalloon Focal Ablation System for Residual Barretts Esophagus Post Ablation; a Pilot Study.
Study Start Date : August 2014
Estimated Primary Completion Date : August 2018
Estimated Study Completion Date : August 2019

Arm Intervention/treatment
Experimental: focal cryo ablation
in this pilot study 10 subjects with residual barrett's esophagus (less than 3 cm) post ablation will under go one CryoBalloon Focal Ablation treatment
Device: CryoBalloon Focal Ablation

Primary Outcome Measures :
  1. eradication of barrett's esophagus and/or dysplasia [ Time Frame: 3 to 6 months post treatment ]
    Surveillance endoscopy with 4-quadrant biopsies every 1 cm from the gastric cardia, proceeding proximally at the length of the original BE lesion/s will be performed per standard clinical practice at 3 or 6 months post ablation. The presence of Barrett's Esophagus and degree of dysplasia will be confirmed by histopathologic diagnosis
