OBJECTIVE To evaluate the diagnostic value of endoscopic ultrasonography (EUS) for submucosal tumors (SMTs) of upper gastrointestinal tract. METHODS 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. RESULTS 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%. CONCLUSIONS 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.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D019160 Endosonography Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.
