Techniques for EUS-guided FNA cytology.
This article addresses the technique of endoscopic ultrasound-guided fine-needle aspiration of solid lesions to obtain cytologic specimens. The technique can be broken down into a sequence of steps. The ultimate goal is to maximize the likelihood of obtaining adequate tissue for diagnostic purposes. This requires a technique that ensures that the needle can be moved inside the lesion, under ultrasound guidance, as widely as possible, as easily as possible, and safely. The other variables such as suction, needle type, and stylet use are of secondary importance.
