Intervention

Device:
• Acell MatriStem® Surgical Matrix
Extracellular matrix (ECM) product that is composed of collagen and natural proteins that provide a re-absorbable scaffold for tissue remodeling to facilitate constructive healing following endoscopic submucosal resection (EMR). Covers the defect site following mucosal resection using endoscopy clips or X-tac. The device will remain attached to the esophagus and integrate with native tissue over time.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Completeness of EMR Site Healing at Follow up Endoscopy	Number of subjects to have complete endoscopic submucosal resection (EMR) site healing determined by the ability of the resection site to lift with saline injection during follow-up endoscopy.	approximately 3-4 months post EMR
Secondary	Presence of Stricture Formation at Follow up Endoscopy	Number of subjects to have symptomatic esophageal stricture formation requiring dilation, preventing dysphagia as determined by questionnaires, and mitigating formation of post-resection scarring as determined by blinded comparison of pre- and post-resection images (taken using white-light endoscopy and electron chromoendoscopy).	approximately 3-4 months post EMR
