OBJECTIVE: To evaluate the short-term outcomes and complication management of submucosal tunneling endoscopic resection(STER) for esophageal @entity5 ( @entity5 ) originating from the muscularis propria( @entity2468 ) layer. METHODS: Clinical data of 48 @entity1 with esophageal @entity5 from @entity2468 layer undergoing STER in the Department of Gastroenterology, the First @entity1 's Hospital of Xiangshan, Zhejiang, and the Endoscopy Center of Zhongshan Hospital, Fudan University, Shanghai between September 2013 and August 2014 were retrospectively analyzed. The clinicopathological features, complication management, and short-term outcomes were evaluated. RESULTS: All the @entity1 underwent STER successfully. The complete resection rate was 100%. The mean maximum diameter of the lesions was (22.9  12.1) mm (range 9.0-60.0 mm), and the mean operation time 41.8 min (range 15.0-140.0 min). Intraoperative @entity3137 occurred in 5 @entity1 (10.4%), which was successfully clipped, @entity516 in 2 @entity1 (4.2%) and @entity9285 in 3 @entity1 (6.3%), which were successfully controlled with conservative treatments. Five @entity1 (10.4%) had postoperative severe @entity662 . Seven @entity1 (14.6%) developed @entity221 , among them, 5 were managed by conservative therapy, and 2 were @entity281 , who were successfully treated after reclosing the ruptured tunnel entry with clips. All the @entity5 had @entity5 -free resection margins. The average length of postoperative hospital stay was 2.4 days (range 1-13 days). Local recurrence and distant metastasis did not occur during mean 6.8 months (range 2-12 months) follow up. CONCLUSIONS: STER appears to be a safe and effective option for esophageal @entity5 originating from @entity2468 layer. Common complications related to STER often can be successfully controlled with conservative treatments.
