Core Tip

Core Tip: Endoscopic ultrasound (EUS)-guided tissue acquisition (TA) began in 1992 as EUS-guided fine-needle aspiration (FNA). Recently, with the development of personalized medicine and precision treatment, the fine-needle biopsy (FNB) needle was developed. EUS-FNB is rapidly replacing EUS-FNA for pancreatic cancer. The EUS-TA strategy with three or more punctures, the stylet retraction method, the torque or fanning technique, and a 22-G or thicker FNB needle may be effective in patients with solid pancreatic tumors scheduled for treatment, including personalized medicine. It is also important clinicians are familiar with both procedures, as EUS-FNA is occasionally necessary when FNB is unsuccessful.
