Endoscopic ultrasound-guided fine needle aspiration of the pancreas

Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) is performed with a linear echoendoscope using endoscopic imaging as well as ultrasound guidance. During FNA, the needle can be seen entering the pancreas. For cystic lesions, fluid is removed. For solid lesions, cytologic material is sampled.
