- Abstract
Background: Data on the use of EUS-guided fine-needle biopsy (EUS-FNB) of solid liver mass (SLM) for pathology is limited., Methods: To prove superiority of the diagnostic rate of the newly designed modified Menghini-type needle with a beveled side-slot near the needle tip with slot cutting edge directed 20-gauge antegrade bevel (group A) over the original 22-gauge reverse bevel (group B) for EUS-guided fine-needle biopsy (EUS-FNB) of solid liver mass (SLM) in a prospective crossover randomized controlled trial., Results: The overall diagnostic accuracy rate of the 52 passes was 86.5% (45/52) and of group A versus B were 88.5% (23/26) versus 84.6% (22/26), respectively, p = 0.858. Tissue adequacy levels of both groups were not significantly different (grade A: B: C = 18:6:2 versus 16:7:3), p = 0.839). Grading of blood contamination of both groups was not significantly different. However, it was found that the group-A needles could biopsy tissue of significantly longer length than that of the group B; 1.3 cm (SD = 0.76) versus 0.8 cm (SD = 0.54); p = 0.007., Conclusion: The use of EUS-FNB of SLM is highly effective with similar levels of efficacy and number of adverse events between both types of needles., The Trial Registration Number: Thai Clinical Trial Registration No. TCTR2018081002., (Copyright © 2021 International Hepato-Pancreato-Biliary Association Inc.
