Epithelial cell sheet transplantation into subject 3. A Endoscopic image of the stenosis just before EBD at cell sheet transplantation. B Contrast esophagography during balloon dilation just before cell sheet transplantation. Arrows indicate the stenosis. The balloon was filled with contrast at 1 atm of internal pressure. C Enlarged image of the esophageal stenosis. The dotted line on the left is approximately 22.7 mm and the right is 21.8 mm. D Endoscopic image after balloon dilation just before cell sheet implantation. Arrows indicate the location of the laceration caused by balloon dilation. E The cell sheets were attached to the mucous dehiscence above the laceration using the transplantation device. F Contrast esophagography approximately one month before cell sheet transplantation. Arrows indicate anastomotic stenosis. G Contrast esophagography approximately 3 months (91 days) after cell sheet transplantation. Arrows indicate stenosis. H Contrast esophagography approximately five and a half months (166 days) after cell sheet transplantation. Arrows indicate the stenosis. I Endoscopic image of the stenosis approximately one month (28 days) after cell sheet transplantation. Arrows indicate the location of the laceration caused by balloon dilation just before transplantation
