“…Success of percutaneous biopsy techniques has rapidly increased in the last quarter century along with the rapid advancements in biopsy devices and in US and CT technologies, which are the guided imaging techniques in percutaneous biopsy procedure and this technique has become essential in the clinical practice for tissue diagnosis of hepatic mass lesions (10,11). In addition, it has been stated that US-guided biopsy enables histological diagnosis with a high accuracy even in small (≤1 cm) lesions (12).…”

“…Numerous different biopsy devices and needles that provide to obtain high-quality specimens appropriate for histopathological examination have been introduced for the use of operators (10). In general, a side-notch cutting needle in 18G thickness, which is compatible with automatic biopsy gun, is used in our clinic for liver biopsy procedures.…”

Aim: To evaluate the role of using 18 Gauge (G) and 20G sharp needles in ultrasonography (US)-guided percutaneous liver mass biopsy regarding diagnostic success and efficacy is aimed. Materials and Methods: Sixty patients who underwent US-guided liver mass biopsy using 18G and 20G cutting needles were included in the study. Definite diagnosis was established based on results of histopathological examinations of the biopsied lesions, follow-up clinical and imaging findings and for performed patients the results of repeated biopsy. In addition, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy were calculated for 18G and 20G needles. Results: Among 60 liver masses, definite diagnosis was malignant in 54 (90%) masses and benign in 6 (10%) masses. Sensitivity, specificity, PPV, NPV, and diagnostic accuracy were 90.7%, 100.0%, 100.0%, 75.0%, and 91.6%, respectively, for the liver mass biopsies performed with 18G needles. These values were 87.0%, 100.0%, 100.0%, 66.7%, and 88.3%, respectively, for the liver mass biopsies performed with 20G needles. No significant difference was determined between the results found for the use of 18G needle and 20G needle in US-guided cutting needle biopsy performed in hepatic masses (p=0.540) Conclusion: The present study demonstrated that 18G and 20G sharp needles had similar diagnostic success and efficacy in US-guided percutaneous biopsy of liver mass lesions. Owing to its fine calibration, 20G sharp needle can be preferred in high-risk patient groups, particularly in those with bleeding disorder.
