    Abstract:
    A 58-year-old man was followed up for esophageal submucosal tumor at our hospital. Esophagogastroduodenoscopy showed the tumor was located on the left side of the thoracic esophagus and had gradually increased in size. Endoscopic ultrasonography revealed an 18×11.5mm hypoechoic tumor connected to the fourth layer of the esophagus and fine needle biopsy revealed c-kit(+), desmin(-)and a-SMA(-). Double-contrast barium study detected a tumor of diameter 20 mm in the middle-lower thoracic esophagus. We diagnosed an esophageal gastrointestinal stromal tumor(GIST)and performed mediastinoscope-assisted transhiatal esophagectomy with gastric tube reconstruction. The maximum tumor diameter was 25mm and pathological evaluation showed c-kit(+), Ki-67 index of less than 5%, and low-risk GIST by the Fletcher classification. Mediastinoscope-assisted transhiatal esophagectomy might be a useful approach for esophageal GIST, because dissection along the esophagus can be performed without thoracotomy.
