Endoscopic ultrasoundguided fine needle aspiration (EUS-FNA) is performed using the curved linear array echoendoscope (Figure 1) using various needles (Figure 2). The recently introduced forward viewing linear echoendoscope is gaining momentum in endoscopic ultrasound-guided interventions (Figure 1). EUS-FNA is minimally invasive that is utilized for procurement of tissue from unresectable tumors. EUS-guided fine needle aspiration is used increasingly for the diagnosis of mediastinal, pancreatic and gastric tumors, however, not much is known about EUS-FNA in hepatic lesions. EUS imaging of the liver is currently limited to the left lobe, the proximal right lobe, the hilum and part of the intrahepatic biliary tract. EUS-FNA may be considered as an alternative to liver percutaneous biopsy in patients at high risk of bleeding or with small lesions of the liver uncharacterized by cross-sectional abdominal imaging. EUS-guided biliary drainage (EUS-BD) was developed using a curved linear array echoendoscope for cases with failed endoscopic biliary drainage. Table 1 AbstractEndoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) of the liver is a safe procedure in the diagnosis and staging of hepatobiliary malignancies with a minimal major complication rate. EUS-FNA is useful for liver lesions poorly accessible to other imaging modalities of the liver. EUS-guided FNA of biliary neoplasia and malignant biliary stricture is superior to the conventional endoscopic brushing and biopsy.

Diagnosis and Treatment of Gallbladder Polyps: Current Perspectives

“…59 On the other hand, endoscopic or percutan ultrasound-guided fine needle aspiration cytology offer clinical benefits for differential diagnosis of gallbladder wall pathologies. 47,60 Ogura et al also suggested that EUS-FNA is more sensitive, specific and accurate than ETGD for cyto-histological diagnosis of gallbladder lesions. 47 There are no specific laboratory findings refer to GBPs.…”

“…The use of EUS is not limited to visualization, but also allows tissue biopsy sampling for diagnostic purpose. EUS has played a major role in revolutionizing the diagnosis of the focal liver lesions (17).…”

Role of endoscopic ultrasound in liver disease: Where do we stand in 2017?

“…EUS-FNA is a minimally invasive procedure that is utilized for procurement of tissue of hepatic lesions. Currently, its use is limited to the left lobe, the proximal right lobe, the hilum and part of the intrahepatic biliary tract[ 17 ]. EUS-FNA has a theoretical advantage over classical percutaneous biopsy in patients with cirrhosis, since percutaneous approach may be difficult in these patients owing to the presence of ascites and coagulopathy[ 4 ].…”
