Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
At the time of the procedure, participants will undergo TECR with ECM placement using a fully covered self-expanding metal stent to temporarily hold the ECM in place. Prior to hospital discharge, a barium swallow test (BaSW) will be performed at Day 1 following the study procedure to evaluate the passage of contrast through the GEJ. If the BaSW results in suspicious findings of esophageal perforation or mucosal necrosis, an upper endoscopy will be performed for further evaluation. The first primary safety endpoint for this study will be assessed following the procedure and BaSW and before discharge from the hospital. At this time point any adverse events will be assessed and recorded.
All subjects will undergo the same follow-up procedures, including questionnaires and post-procedure EGDs performed at Week 2, Month 1, Month 3, Month 6, Month 9 and Month 12 to visually assess tissue healing, recurrent disease, and if stricture formation is present. Biopsies will be taken during follow-up EGDs so that pathology can rule out recurrence of BE and HGD. Subjects will have a barium swallow x-ray at Month 1, Month 3, Month 6, Month 9, and Month 12 to evaluate the potential presence of stricture formation.
During Week 2 EGD, the stent will be removed during the upper endoscopy. If at any time point a subject has dysphagia with stricture formation (30% reduction in esophageal luminal diameter), routine dilation using a balloon catheter will be performed during the EGD. Validated questionnaires including dysphagia severity questionnaire, SF-36 and GERD-HRQL will be administered to objectively assess the severity of symptoms and quality of life based upon self-reported data. Additionally, adverse events will be assessed and recorded at all follow-up time points.
After completion of the Month 12 visit, subjects will be followed on a routine care basis at the Esophageal \& Lung Institute.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
TECR & ECM
Subjects undergoing TECR with ECM placement Intervention is Trans-oral Endoscopic circumferential resection (TECR) with placement of extra-cellular matrix (ECM)
Subjects undergoing TECR with ECM placement (ACell MatriStem, Boston Scientific WallFlex))
TECR will be performed to resect the entire length and area of BE lesion.
ECM PLACEMENT:
Following resection, the exposed area will be covered with a 6 ply sheet of ACell MatriStem® Surgical Matrix PSMX ECM (ACell Inc., Columbia, MA). The ECM will be placed and held in position for 14 days (±4 days) using a Boston Scientific WallFlex™ Fully Covered Esophageal Stent (Boston Scientific, Boston, MA).

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
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
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.
