|Official Title:||Pilot Study of Polar Wand Carbon Dioxide Cryotherapy for Barrett's Esophagus With Low Grade and High Grade Dysplasia|
|Study Start Date :||August 2011|
|Actual Primary Completion Date :||April 2014|
|Actual Study Completion Date :||April 2014|
Experimental: Polar Wand Treatment
Cryotherapy device utilizing carbon dioxide (room temperature gas) for treatment of GI neoplasia
Device: Polar Wand carbon dioxide cryotherapy
Patients with Barrett's esophagus dysplasia will be treated with the Polar Wand device at 0 month, 2 and 4 months,6 months (with four quadrant surveillance biopsies), 8 and 10 months (treatment as necessary), and, at 12 months for final surveillance with biopsies throughout entire initial Barrett's segment length.
- Reduction in Barrett's Histology Grade, Using the Modified Vienna Classification [ Time Frame: 12 months ]The reduction of Barrett's segment length and histology classification will be measured at 12 months.
- Reduction in Barrett's Segment Length, Using the Prague Classification [ Time Frame: 6 and 12 months ]
- Assessment of Complications [ Time Frame: 12 months ]Specific complications are GI Bleeding and Perforation and Stricture and Ulceration
- Assessment of Post-ablation Symptoms [ Time Frame: 12 months ]Specific symptoms (frequency and severity) are chest pain, difficulty swallowing, painful swallowing, nausea or vomiting, sore throat
- Reduction in Barrett's Histology Grade, Using the Modified Vienna Classification [ Time Frame: 6 months ]The reduction of Barrett's segment length and histology classification will be measured at 6 months.
