Abstract
Abstract In the past few years, endoscopic ultrasound (EUS)-guided fine-needle biopsy (EUS-FNB) has superseded EUS-fine-needle aspiration (EUS-FNA) for EUS-guided tissue acquisition. EUS-FNA does not retain the stroma as well as the surrounding tissue architecture and therefore had limitations in achieving a definitive diagnosis. Development of EUS-FNB needles had improved the diagnostic ability of EUS by providing core tissue sample that not only preserves surrounding tissue architecture but also provides adequate material for molecular typing and gene profiling of sampled lesions. At present, there are three commercially available third-generation EUS-FNB needles with unique needle tip designs. In this review, we aim to elucidate the technical aspects of the available EUS-FNB needles.
期刊介绍：
The Journal of Digestive Endoscopy (JDE) is the official publication of the Society of Gastrointestinal Endoscopy of India that has over 1500 members. The society comprises of several key clinicians in this field from different parts of the country and has key international speakers in its advisory board. JDE is a double-blinded peer-reviewed, print and online journal publishing quarterly. It focuses on original investigations, reviews, case reports and clinical images as well as key investigations including but not limited to cholangiopancreatography, fluoroscopy, capsule endoscopy etc.
