Clinical Application On Endoscopic Mucosal Resection Of Esophageal Submucosal Tumors

Objective:to evaluate the value of endoscopic mucosal resection (EMR) for treatment of esophageal submucosal tumors(SMTs).Methods:66 esophageal submucosal tumors less than 2cm of diameter which come from muscularis and submucosa for 63 patients, which were conformed by endoscopy and endoscopic ultrasonography (EUS), from January 2008 to October 2009. Among 63 patients, there were 33 men and 30 women, and the age was from 22 to 73 years old, and the average age was 44.4 years old. All lesions were treated with EMR, All patients were treated with fasting, restraining acid secretion, protecting mucous membrane and other treatments in post-operation. Patients were followed up with EUS examination at 1 month,3 month and 6 months to observed the wound surface in the post-operation.Results:65 lesions were successfully treated with EMR, and the success rare was 98.5%(65/66). Five cases(7.9%) were complicated with bleeding, during the procedure and were managed and controlled by eletrocogulation and metal tongs, none cases suffered from perforation and bleeding in post-operation. The pathological and immunohisto-chemistry examination proved 58 leimyomas,3 esophageal stormal turmors,2 cysts,1 lipomas,1 granular cell tumor and 1 hemangioma.62 patients were followed up with EUS examination at 1 month,3 month and 6 months, the wound surfaces were completely cured after 1 month, no case suffered from recurrence and stenosis during the followed-up.Conclusion:EMR could treat with esophageal submucosal tumors less than 2cm of diameter which come from muscularis and submucosa completely and could provide complete pathologic date. The method is simple, lower complication and worth spreading for clinical use.
