Core Tip

Core tip: Esophageal strictures after extensive endoscopic submucosal dissection (ESD) reduce quality of life. Endoscopic local injections and the oral administration of steroids are safe and effective for preventing esophageal strictures. In addition, several tissue engineering therapies have been used in attempts to overcome severe esophageal strictures. Cell-based tissue engineering therapy with fabricated autologous oral mucosal epithelial cell sheets has been used to prevent esophageal strictures after ESD in nine patients. This therapy has been shown to be safe and may be widely used in the future.
