{Abstract}: <B>OBJECTIVE: </B>Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) is an important diagnostic tool for suspected parenchymal lesions in the gastrointestinal tract and adjacent organs. Our study aimed to evaluate the safety and effectiveness of EUS-FNA in focal liver lesions (FLLs).<BR><B>METHODS: </B>Data from 88 patients diagnosed with FLLs by imaging who underwent EUS-FNA from 1 January 2017 to 31 August 2022 were reviewed in our retrospective study at the Second Affiliated Hospital of Soochow University and Ruijin Hospital of the School of Medicine of Shanghai Jiao Tong University. The EUS-FNA biopsy results were compared with the final diagnosis to evaluate diagnostic value. The relevant factors were analysed to determine their influence on EUS-FNA biopsy results.<BR><B>RESULTS: </B>The 88 patients analysed in this study resulted in a final diagnosis of 86 malignant and two benign cases. The overall diagnostic accuracy of EUS-FNA in FLLs was 93.18 % (82/88; 95 % Confidence Interval [CI], 87.9-98.5), with a sensitivity, specificity, positive predictive value, and negative predictive value of 93.02 % (80/86; 95 %CI, 87.6-98.4), 100 % (2/2; 95 %CI, 100-100), 100 % (80/80; 95 %CI, 100-100), and 25 % (2/8; 95 %CI, -5-55.0), respectively. The parameters related to lesion and procedure were not significantly different between these two groups (p > 0.05). The number of puncture needles in the groups showed a statistically significant difference between multiple and single punctures (p = 0.001).<BR><B>CONCLUSIONS: </B>Our data revealed that EUS-FNA is a safe and reliable diagnostic method for FLLs that shows high accuracy.
