Successful en bloc endoscopic full-thickness resection of a giant cervical esophageal leiomyoma originating from muscularis propria

摘要

BackgroundEsophageal leiomyomas, the most common benign primary tumors of the esophagus, are esophageal subepithelial lesions treated by surgery traditionally. In recent years, endoscopic submucosal dissection and related endoscopic treatment techniques are adopted by endoscopists to resect gastrointestinal submucosal tumors. But if a giant esophageal leiomyoma approaches the esophagus entrance and originates from the deep layer of muscularis propria, it will be difficult for both endoscopic resection and surgical treatment. Especially, endoscopic resection has a high risk of huge perforation difficult to be sutured.
