Mucosal Impedance
Aim 1: Mucosal impedance will be measured by an endoscopic probe 1 cm above the gastroesophageal junction, 5 cm above the gastroesophageal junction and in the proximal esophagus in an area not exposed to the index therapeutic radiofrequency ablation. Aim 2: Mucosal impedance will be measured 1 cm above gastroesophageal junction, 1 cm below previous squamous columnar junction, 1 cm above previous squamocolumnar junction.
Research Biopsies
Aim 1: Research biopsies will be obtained at 1 cm above the gastroesophageal junction, 5 cm above the gastroesophageal junction, and in the proximal esophagus in an area not exposed to the index therapeutic radiofrequency ablation. Aim 2: Aim 2: Research biopsies will be taken 1 cm above gastroesophageal junction, 1 cm below previous squamous columnar junction, 1 cm above previous squamocolumnar junction.
Volumetric Laser Endomicroscopy
Aim 2: Volumetric laser endomicroscopy will be done and marked at 1 cm above gastroesophageal junction, 1 cm below previous squamous columnar junction, 1 cm above previous squamocolumnar junction.
