ABSTRACT
Objective To evaluate the accuracy and clinical application of endoscopic ultrasound guided fine needle aspiration (EUS-FNA) in diagnosis of occupying lesions in upper digestive tract and its pe-ripheral areas. Methods The data of 64 patients who underwent EUS-FNA for occupying lesions in upper di-gestive tract, between July 2006 and December 2007, were retrospectively analyzed. Results EUS-FNA was successfully performed on 62 patients, with a success rate of 96.88%. The overall diagnostic accuracy, sensi-tivity, specificity, positive predictive value and negative predictive value of EUS-FNA for occupying lesions in upper digestive tract and its peripheral areas were 88.71%, 86.54%, 100.00%, 100.00%, and 58.82%, respectively. There was no significant difference between the foei larger and smaller than 3cm (P > 0.05), re-garding the diagnostic accuracy and average puncture numbers. Diagnostic accuracy of those with real-time cy-tolngical evaluation was significantly higher than those without (P=0.029), and the puncture numbers were less (P=0.001). Among the total 99 punctures, the positive diagnostic accuracy of those with 5ml negative pressure suction was significantly higher than those of 10 ml (P = 0.044). Conclusion EUS-FNA is a safe and applicable approach to diagnosis of occupying lesions in upper digestive tract and its peripheral areas with higher diagnostic accuracy, sensitivity, specificity and positive predictive value. Moreover, the real-time cyto-logical evaluation and adequate negative pressure might facilitate the diagnosis accuracy.
