Abstract Background and study aims Endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) represents a standard method for tissue acquisition of lesions adjacent to the gastrointestinal wall. Needles of 19 gauge acquire more tissue than needles with a smaller diameter, but are often unable to penetrate solid, rigid masses. In this study we evaluated a novel prototype that links forward movement of the needle to rotation of the needle tip. Materials and methods Two needle-models that generate either a regular axial movement or a combination of axial movement with rotation of the needle tip were compared ex vivo for measurement of pressure needed to penetrate artificial tissue. Furthermore, a standard 19-gauge EUS-FNB needle was compared to a modified model (“Twist Needle”) in an ex vivo model to measure the amount of tissue obtained. Results Pressure measurements using the rotating needle revealed that significantly less pressure is needed for penetration compared to the regular axial movement (mean ± SEM; 3.7 ± 0.3 N vs. 5.5 ± 0.3 N). Using the modified 19-gauge “Twist Needle” did not diminish tissue acquisition measured by surface amount compared to a standard needle (37 ± 5 mm² vs. 35 ± 6 mm²). Conclusion The method of rotation of an EUS-FNB needle tip upon forward movement requires less pressure for penetration but does not diminish tissue acquisition. Hence, the concept of our “Twist Needle” may potentially reduce some of the current limitations of standard EUS-FNB.

Abstract Background and study aims Although newer needle designs are thought to improve diagnostic outcomes of endoscopic ultrasound-guided fine-needle biopsy, there is limited evidence on their diagnostic performance. The aim of this meta-analysis was to provide a pooled estimate of the diagnostic performance and safety profile of Franseen and Fork-tip fine-needle biopsy needles. Patients and methods Computerized bibliographic search on the main databases was performed through March 2019. The primary endpoint was sample adequacy. Secondary outcomes were diagnostic accuracy, optimal histological core procurement, mean number of needle passes, pooled specificity and sensitivity. Safety data were also analyzed. Results Twenty-four studies with 6641 patients were included and pancreas was the prevalent location of sampled lesions. Overall sample adequacy with the two newer needles was 94.8 % (93.1 % – 96.4 %), with superiority of Franseen needle over Fork-tip (96.1 % versus 92.4 %, P < 0.001). Sample adequacy in targeting pancreatic masses was 95.6% and both needles produced results superior to fine-needle aspiration (FNA) (odds ratio 4.29, 1.49 – 12.35 and 1.79, 1.01 – 3.19 with Franseen and Fork-tip needle, respectively). The rate of histological core procurement was 92.5%, whereas diagnostic accuracy and sensitivity were 95 % and 92.8 %, again with no difference between the two needles. Number of needle passes was significantly lower in comparison to FNA (mean difference: –0.42 with Franseen and –1.60 with Fork-tip needle). No significant adverse events were registered. Conclusion Our meta-analysis speaks in favor of use of newer biopsy needles as a safe and effective tool in endoscopic ultrasound-guided tissue acquisition.
