Patch esophagoplasty: esophageal reconstruction using biologic scaffolds.

Area of Science:

• Regenerative Medicine
• Surgical Innovation
• Gastroenterology

Background:

• Esophageal reconstruction techniques are suboptimal, with high morbidity from primary closure and contraindications for synthetic materials.
• Degradable extracellular matrix (ECM) scaffolds show promise in preventing strictures after endoscopic mucosal resection.
• A novel surgical technique using ECM scaffolds for esophageal reconstruction is proposed.

Purpose of the Study:

• To evaluate the efficacy of a novel patch esophagoplasty technique using ECM scaffolds for esophageal reconstruction.
• To assess the safety and clinical outcomes of this regenerative medicine approach.

Main Methods:

• Four patients underwent patch esophagoplasty using porcine urinary bladder ECM scaffolds.
• The ECM patch replaced the full-thickness esophageal wall and was sutured to remaining esophageal edges.

Main Results:

• All patients achieved favorable clinical outcomes with prompt oral intake restoration.
• Esophageal emptying was adequate, with complete mucosal remodeling and minimal area contraction observed.
• One patient experienced a spontaneous micro-leak, and another required surgery for a separate stricture.

Conclusions:

• ECM scaffold-based patch esophagoplasty offers a promising alternative for esophageal reconstruction.
• Further prospective studies and long-term follow-up are necessary to validate this regenerative approach.
