ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the diagnostic value of endoscopic ultrasonography (EUS) for submucosal tumors (SMTs) of upper gastrointestinal tract.</p><p><b>METHODS</b>A retrospective analysis was made based on clinical data of 206 upper gastrointestinal SMTs patients from January 2009 to July 2013 in The First Affiliated Hospital of Soochow University. Preoperative EUS findings were compared with postoperative pathological diagnosis, and the sensitivity, specificity and accuracy of EUS diagnosis in property and layer origin of SMTs were calculated.</p><p><b>RESULTS</b>The sensitivity, specificity and accuracy of EUS diagnosis in SMTs property were 60.2%, 67.1% and 61.2%. The sensitivity, specificity and accuracy of EUS diagnosis in layer origin of SMTs were 98.0%, 98.2% and 98.1%.</p><p><b>CONCLUSION</b>EUS has limited value in the diagnosis of property of SMT, and has high accuracy of identifying the origin layer, which is helpful to choose therapeutic schedule of SMT under endoscopy.</p>
