Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
All subjects will receive narcotic analgesics to control symptoms.
Endpoints related to pathology will be assessed by two independent reviewers, one from the Institution's Department of Pathology, and one from an independent Pathology lab chosen by the sponsor. The reviewers will evaluate the pathology slides to assess maximal extent of depth of injury, side effects, and pathological changes associated with CSA. All reviewers will be blinded to the treatment conditions of the specimens.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Esophagectomy planned based on clinical situation not related to this study.
* Deemed operable based on institutional criteria.
Exclusion Criteria
* Esophageal stricture preventing passage of endoscope or catheter.
* Known history of unresolved drug or alcohol dependency that would limit ability to comprehend or follow instructions related to informed consent, post-treatment instructions, or follow-up guidelines.
* Refusal or inability to give consent.
* Concurrent chemotherapy.
* Prior or concurrent endoscopic ablation therapy within 4 cm from the CSA treatment area including, but not limited to, cryospray therapy, laser treatment, photodynamic therapy, multi-polar electro coagulation, endoscopic mucosal resection, radiofrequency ablation, or argon plasma coagulation.
