Abstract: Objective To assess the safety and reliability of submucosal tunneling endoscopic resection(STER)for the treatment of submucosal tumor originating from the muscularis propria layer of the esophagus.Methods Data of 26 patients with lesions in esophageal muscularis propria treated with STER were retrospected.Feasibility,safety and effects were evaluated accordingly.Results A total of 26 cases of submucosal tumor originating from the muscularis propria layer of the esophagus were treated by STER,25 cases were en bloc resected,the successful rate was 96.2%(25/26).The size of lesions ranged from 1.0to 2.6cm with a mean size of(1.7±0.5)cm.The mean STER procedure time was(63±23)min(ranged from 33 to 157 min).During the procedure,subcutaneous and mediastinal emphysema occurred in eleven patients(42.3%).Two patients(7.7%)developed pneumothorax,and other one(3.8%)developed pneumoperitoneum.All of them recovered after conservative treatment.No patient developed delayed hemorrhage,esophageal fistula or mediastinal infection after STER.The histological diagnoses were21 leiomyomas,3gastrointestinal stromal tumors and 1granulosa cell tumor.No residual or recurrent tumors were detected during the follow-up period(>3 months).Conclusion STER appears to be a safe,feasible and effective procedure for treatment of small(< 3.0cm)submucosal tumor originating from the muscularis propria layer of the esophagus.It can provide accurate histopathological evaluations and is a technique to be worth applying and popularizing.
