With the improvement of the endoscope technology, transoral surgery supported by endoscopy is widely spreaded as the less invasive therapeutic method for the pharynx superficial cancer. To prevent early complications by inflammations and late complications by scar contracture we conducted the non-clinical study of squamous epithelium cell sheet transplantation for porcine model to show the anti-inflammatory action, and inhibition of excessive fibrosis. To transplant cell sheets onto entire field of the pharynx after procedure, novel devices were designed and developed with a 3-D printer. Successful cell sheets transplantation are conducted for all models and the effect of transplantation has been confirmed. We obtained non-clinical proof of consent which lead to the clinical application.
