Abstract:
ObjectiveTo study the diagnostic and therapeutic value of endoscopy for gastrointestinal (GI) schwannoma.MethodsWe retrospectively studied data of 13 patients who underwent endoscopy and were confirmed as having GI schwannoma by pathology in our hospital during January 2006 and July 2011.ResultsSchwannoma of 8 patiets located in stomach,3 in esophagus and 2 in colon.Endoscopic ultrasonography showed schwannoma originated from muscularis propria,characterized by hypoecho.Twelve patients received endoscopic treatment,and 11 were successfully removed.The en bloc resection rate was 91.7％.Among them,6 were treated by endoscopic submucosal excavation,4 by endoscopic full-thickness resection and one by submucosal tunnel endoscopic resection.Another patient with schwannoma located in esophagus with a maximum diameter of 4.7 cm was transferred to thoracic surgery since the tumor had a wide base even after partial resection.No bleeding,inflammation or abscess occurred.The average follow-up time was 23.3 ± 10.8 months ( range,6-36 months).No metastasis or recurrence was found during follow-up.ConclusionEndoscopy and endoscopic ultrasonography,safe and efficacious,are valuable for the diagnosis and treatment of GI schwannoma.
