概要	Background The utility of endoscopic transplantation of epithelial cell sheets to ulcer sites after endoscopic submucosal dissection (ESD) has been shown to prevent scar stenosis after ESD of early esophageal cancer. Previously, our group reported use of an endoscopic transplantation device fabricated with a 3-dimensional printer. Cell sheets are transplanted to the esophageal wound site with the following procedure: first, a cell sheet harvested from temperature-responsive culture dishes is placed on the device's deflated balloon surface and transported to the wound site with endoscopic forceps; second, by applying pressure from inflating the balloon locally at the wound site, the cell sheet is successfully transferred and adhered to the wound tissue; third, the balloon is deflated, and the device is removed. By repeating the procedure, several cell sheets can be safely transplanted to a wider ESD area. Nonetheless, possible damage to cell sheets using this procedure has not yet been assessed.
