Trial Title: TECR & ECM Placement for Esophageal High Grade Dysplasia

Study Design Characteristics:
- Allocation: None
- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~1. Be at least 18 years of age and no more than 80 years of age.~2. Have an established diagnosis of HGD~   a. Specific diagnosis and grading will be determined by pathology review of biopsy tissue collected during baseline EGD as part of a patient's standard of care.~3. Have no evidence of lymphovascular invasion.~4. Have no lymph node or other metastatic involvement based on EUS and FDG-PET/CT.~5. Diameter of affected tissue must warrant circumferential excision a. Subjects must have biopsy confirmed HGD in three of four esophageal quadrants at two levels spaced two centimeters apart (minimum of 6/8 biopsies indicating HGD). If two biopsies are normal (contain no HGD) they must be located on separate levels in two different quadrants.~5. Must be an appropriate or reasonable surgical candidate. 6. Have demonstrated an understanding and signed an approved informed consent form for participation in this study.~Exclusion Criteria:~1. Have lesions into or deeper than mucosal layer (superficial (T1a) Esophageal adenocarcinoma).~   a. Those requiring endoscopic submucosal dissection (ESD) are not eligible for this study~2. Have presence of lymphovascular invasion.~3. Require resection length longer than 10 cm.~4. Have any lymph node or other metastatic involvement based on EUS and FDG-PET/CT.~5. Have history of any kind of previous esophageal surgery (i.e. anti-reflux surgery).~6. Are pregnant or planning to become pregnant.~7. Have coagulation disorders.~8. Have a known hypersensitivity to porcine-based materials.~9. Have an uncontrolled comorbid medical condition that would adversely affect participation in the trial.~10. Has a clinically significant psychological illness that in the physician's opinion would prohibit the subject's ability to meet the protocol requirements.~11. Are unable or unwilling to provide informed consent and/or fulfill the protocol follow-up requirements.~    -
