Abstract:Endoscopic submucosal dissection (ESD) is a minimally invasive technique that utilizes special electrosurgical knives under endoscopic guidance to completely remove lesions, and has become a primary treatment for early esophageal cancer and precancerous lesions. However, esophageal stenosis caused by large postoperative mucosal defects seriously affects patients' quality of life. Although various strategies exist to prevent post-ESD esophageal stenosis, including physical dilation, pharmacoprevention, biomaterial repair, and tissue engineering/regenerative medicine approaches (e.g., mucosal transplantation), no consensus exists on the optimal prevention strategy. This review discusses advances in the prevention of esophageal stenosis after ESD.
