Macroscopic visible core length can predict the histological sample quantity in endoscopic ultrasound-guided tissue acquisition: Multicenter prospective study

Junichi Kaneko et al.

Summary: Measuring MVC length during EUS-TA using a 22-G Franseen needle can predict histological sample quantity, which is clinically significant.

Comparison of fine-needle aspiration and fine-needle biopsy devices for endoscopic ultrasound-guided sampling of solid lesions: a systemic review and meta-analysis

Priscilla A. van Riet et al.

Summary: The meta-analyses showed that fine-needle biopsy (FNB) outperformed fine-needle aspiration (FNA) in obtaining tissue samples, with higher diagnostic accuracy and tissue core rate, and requiring fewer passes for diagnosis. Among different FNB devices, forward-facing bevel needles demonstrated higher diagnostic accuracy compared to reverse bevel needles. However, due to low quality of evidence, further research is needed to make strong recommendations on the optimal FNB design.

Comparative diagnostic accuracy of EUS needles in solid pancreatic masses: a network meta-analysis

Samuel Han et al.

Summary: Based on a network meta-analysis, FNB needles demonstrate superior diagnostic performance in sampling pancreatic masses compared to FNA needles, with 22G FNB needles showing the highest performance.

Comparison of contrast-enhanced versus conventional EUS-guided FNA/fine-needle biopsy in diagnosis of solid pancreatic lesions: a randomized controlled trial

In Rae Cho et al.

Summary: The study found that there was no significant difference in diagnostic sensitivity for solid pancreatic lesions between CEH-EUS and conventional EUS. CEH-EUS-guided FNA/FNB sampling may not need to be routinely used and can be selectively considered for small, indeterminate lesions.

Contrast-enhanced harmonic endoscopic ultrasound-guided fine-needle aspiration versus standard fine-needle aspiration in pancreatic masses: a meta-analysis

Antonio Facciorusso et al.

Summary: This meta-analysis found that CH-EUS-FNA may provide superior diagnostic outcomes compared to standard EUS-FNA in patients with pancreatic masses, with higher diagnostic sensitivity, accuracy, and sample adequacy. Further trials are needed to confirm these results.

THE ASIAN FEDERATION OF SOCIETIES FOR ULTRASOUND IN MEDICINE AND BIOLOGY (AFSUMB) GUIDELINES FOR CONTRAST-ENHANCED ENDOSCOPIC ULTRASOUND

Masayuki Kitano et al.

Summary: The Asian Federation of Societies for Ultrasound in Medicine and Biology has published consensus guidelines on CH-EUS techniques and indications based on scientific evidence, aiming to assist endosonographers in conducting CH-EUS. The guidelines include six statements on technical aspects and thirteen statements on indications.

Endoscopic Ultrasound-guided Fine-needle Biopsy With or Without Rapid On-site Evaluation for Diagnosis of Solid Pancreatic Lesions: A Randomized Controlled Non-Inferiority Trial

Stefano Francesco Crino et al.

Summary: The study found that in evaluating solid pancreatic lesions, EUS-FNB without ROSE can achieve high diagnostic accuracy. EUS-FNB without ROSE showed higher tissue core rate and shorter sampling time. Therefore, when using new-generation FNB needles, ROSE should not be routinely recommended.
