Fine-needle biopsy sampling under EUS guidance: Is one needle tip really better than the other?

We read with interest the article by Abdelfatah et al1 regarding the use of 2 new types of core biopsy devices in the sampling of solid lesions under EUS guidance. We commend the authors on their effort to study the sampling capabilities of 2 novel needles, each with a unique tip design. We and others have recently demonstrated a superior tissue yield over conventional FNA using either 1 of the 2 devices2-6; hence the concern over the substantially lower diagnostic yield rates reported by Abdelfatah et al.
