Summary
Brief summary (as posted)
The purpose of this study is to evaluate the treatment effect, depth of injury, and side effects using technology involving the spray of liquid nitrogen through a catheter (CryoSpray AblationTM, "CSA" or "cryospray therapy") onto healthy tissue via esophagogastroduodenoscopy (EGD) using surgical resection specimens from subjects undergoing esophagectomy.
