The proposed study is a single center study consisting of no more than 10 subjects who are undergoing scheduled esophagectomy for reasons unrelated to the study. Subjects will be divided into 2 Groups in a sequential fashion based on the time of enrollment (Subject 1 in Group1, Subject 2 in Group 2, Subject 3 in Group1, Subject 4 in Group 2, etc). Potential study subjects will be referred from clinical practice. After entry into the study with written informed consent, subjects will be scheduled for the EGD with cryospray ablation treatment 7 days prior to the expected esophagectomy date.
