摘要To the Editor:Esophageal leiomyomas are the most common benign primary tumors of the esophagus and the common esophageal subepithelial lesions.The methods of treatment for esophageal submucosal lesions include surgical enucleation,endoscopic submucosal dissection,endoscopic enucleation,and submucosal tunneling with endoscopic removal (STER).Courses of treatment for esophageal leiomyomas are related to a variety of factors,including tumor size,location,morphology,and the patient's symptoms.[1] The size and location of the tumor are the key factors in the selection of excision methods.With the development of endoscopic technology,the more endoscopic resection techniques have been proven to be feasible for tumors originating from muscularis propria,such as endoscopic full-thickness resection and the over-the-scope clipping device system (OTSC).[2] OTSC is used for primary or rescue therapy for patients who undergoing closure of perforations or leaks.[3]
