From May 2012 to December 2017,173 patients with GI SMTs originating from the MP layer underwent STER.After 8 patients were excluded,165 patients were retrospectively enrolled,including 112 men and 53 women,with a mean age of 46.9±10.8 years.The median size of tumor sample was 20.0(range,5.0-80.0 mm).Of the 165lesions,11(6.7%)were located in the upper esophagus,49(29.7%)in the middle esophagus,46(27.9%)in the lower esophagus,and 59(35.7%)in the cardia.Irregular lesions accounted for 48.5%of all lesions.Pathological diagnosis revealed that there were 157(95.2%)leiomyomas,3(1.8%)GISTs,3(1.8%)lipomas,1(0.6%)schwannoma,and 1(0.6%)fibrous tumor.The sizes of each of these three GISTs were 8.0 mm×8.0mm,24.0 mm×11.0 mm,and 25.2 mm×13.2 mm,while their mitotic rates were no more than 5/50 high-power fields.The detailed characteristics of the patients and SMTs are summarized in Table 1.
