ABSTRACT
ObjectiveTo retrospectively evaluate the clinical efficacy of endoscopic submucosal tunnel resection for esophageal leiomyoma originating from muscularis propria.MethodsA total of 16 patients with esophageal mass originating from muscularis propria were recruited with informed consents from January 2011 to November 2011,and underwent esophageal submucosal tunneling endoscopic resection.ResultsAll lesions were completely resected.Histological examinations confirmed the diagnosis of leiomyona,and immunohistochemical staining indicated active hyperplasia in 9 cases.Intraoperative mediastinal,subcutaneous and retroperitoneal emphysema occurred in one patient,and the patient recovered one week later.No other complications or death were recorded.The patients were followed up for six months on average,and no cases of recurrence were found.ConclusionEndoscopic submncosal tunnel resection of esophageal leiomyoma originating from the muscularis propria is a minimally invasive,safe and effective procedure.
