ABSTRACT

Objective To evaluate surgical approach,safety and efficacy of endoscopic submucosal excavation (ESE) for the treatment of gastric submucosal tumors originated from the muscularis propria layer.Methods Fifty-three patients with submucosal tumors of the stomach diagnosed by gastroscope,were examined using endoscopic ultrasonography (EUS) from February 2012 to April 2013.The patients were completed ESE at general anesthesia.Results The diameter of the tumor was from 5 to 35 mm (median 13.2 mm).The tumors of 48 patients were complete resection,the complete resection rate was 90.6％(48/53).The operation time was from 30 to 150 min (median 45 min).Three patients (5.7％,3/53) had impulsivity hemorrhage during ESE,no patients had unmanageable hemorrhea under the gastroscope.Perforation occurred in 6 patients during ESE,perforation rate was 11.3％ (6/53),the perforation was closed by endoclip in 5 patients.Five patients with inability resection and 1 patient with perforation inability closed were treated with surgical operation.None was developed perforation postoperative and hemorrhea.Conclusion ESE is a safety and efficacy method for treating gastric submucosal tumors originating from the muscularis propria layer.
