AbstractBackground: There are very few available data on the novel SharkCore™ needles for EUS-FNB.Aim: Comparison of the performance of the SharkCore™ needles with the standard EUS-FNA needles for the diagnosis of solid upper GI masses.Patients and methods: Single-center, retrospective cohort study in an academic tertiary referral hospital. Patients were matched 1:1 for the site of the lesion and the presence or absence of rapid on-site evaluation (ROSE).Results: A total of 102 patients were included. There was no statistically significant difference in the mean number of passes (3.3 ± 1.3 versus 3.4 ± 1.5; p = .89). Similar results were observed at the subgroup with ROSE (4.3 ± 1.3 versus 3.7 ± 1.5; p = .26). More histological specimens were obtained with the SharkCore™ needles compared to standard needles (59 versus 5%; p < .001). Diagnostic test characteristics were not significantly different (sensitivity: 91.5 versus 85.7; specificity: 100 versus 100%; accuracy: 92.2 versus 85.4% for SharkCore™ versu...

Background and Aims FNA is the primary method of EUS tissue acquisition. In an attempt to improve our yield of EUS-guided tissue acquisition, we compared fine-needle biopsy (FNB) sampling without rapid onsite evaluation (ROSE) with FNA with ROSE and assessed the concordance of FNA and FNB sampling. Methods This was a retrospective review of prospectively collected data from consecutive patients. Patients underwent FNB sampling and FNA of the same single lesion, with the same needle gauge and num...

Background and Aims EUS-guided fine needle biopsy (FNB) sampling and FNA are important methods for obtaining core tissues and cytologic aspirates. To improve the specimen quality for pathologic evaluation, a novel EUS-FNB Shark Core (SC) needle has been designed to acquire core tissue during EUS procedures. We compared the histology yield of EUS-FNB sampling using the SC needle (EUS-FNB-SC) to EUS-FNA in patients who had solid pancreatic and nonpancreatic lesions. Methods This was a retrospectiv...

Background and study aims: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) with 25-gauge needles yields small volume samples that are mainly processed for cytology. Using 25-gauge needles with a core trap may overcome this limitation. This trial compared 25-gauge needles with and without a core trap in terms of their ability to obtain histologic samples from solid pancreatic masses. Patients and methods: Consecutive patients with solid pancreatic masses who presented to eight Japan...

Background and study aims: To overcome the limitations associated with cytology, a uniquely designed needle (ProCore) was introduced in an effort to obtain a core of tissue under endoscopic ultrasound (EUS) guidance. However, studies comparing the sample quality between ProCore and standard-design fine-needle aspiration (FNA) needles have yielded varying results. A systematic review and meta-analysis was therefore conducted to compare the performance of the ProCore and standard FNA needles when ...

ObjectivesEndoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) using standard needles has a high diagnostic value in the evaluation of solid pancreatic masses. Fenestrated needles have been developed to improve the quality of EUS-guided tissue sampling by providing core biopsies (FNB).MethodsPatients with solid pancreatic masses of >2 cm were prospectively included in our study and randomized to receive EUS sampling, using either a standard 22G FNA or a 22G Procore® FNB needle. The main...

Background and study aims: A new core biopsy needle for endoscopic ultrasound (EUS)-guided sampling has recently been developed. The aim of this prospective multicenter study was to compare this needle with a standard needle in patients with solid pancreatic masses. Patients and methods: Consecutive patients with solid pancreatic masses referred to 17 centers for EUS-guided sampling were included. Each patient had two passes with a standard 22G needle and a single pass with a 22G core needle per...

Background/aims Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has been accepted as a reliable tool in diagnosing and staging intra-abdominal tumors. In this study, we aimed to investigate the performance of EUS-FNA in the evaluation of liver masses and its impact on patient management and procedure-related complications retrospectively. Methods Data of patients who underwent EUS-FNA biopsies due to liver masses between November 2017 and July 2018 were retrieved retrospectively. B...

ABSTRACT Background & Aims Given the lack of procedure standardization, findings vary from analyses of pancreatic tissues collected by endoscopic ultrasound-guided fine-needle biopsy. It is not clear which needle and technique yield best specimen for analysis. We compared the specimen quality and accuracy of diagnoses made from samples collected by fine-needle biopsy needles using different collection techniques. Methods Patients found to have pancreatic masses during imaging (n=129) were random...

BACKGROUND EUS-guided tissue acquisition is extensively used, but the optimal sampling device is still a matter of debate. We performed a meta-analysis on studies comparing FNA to FNB needles, in addition to a mutual comparison of FNB needles. METHODS Online databases were searched for randomized controlled studies of at least 50 cases with a suspected solid pancreatic or non-pancreatic lesion that compared FNA to FNB ProCore, SharkCore, or Acquire needles. Outcome measures included diagnostic a...

Background/Aims Recently, a three-plane symmetric needle with Franseen geometry was developed for endoscopic ultrasound-guided fine needle biopsy (EUS-FNB). In this retrospective study, tissue acquisition per pass was compared between 22-gauge Franseen FNB and standard fine needle aspiration (FNA) needles in patients with solid pancreatic lesions. Methods Consecutive patients who underwent EUS-FNA or EUS-FNB for solid pancreatic lesions between October 2014 and March 2018 were retrospectively st...

Abstract Background Pancreatic endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) acquires both direct smear and small core biopsy specimens. Triage protocols for pancreatic FNBs to cytopathology (CP) or gastrointestinal surgical pathologist (GIP) is controversial and varies by institution. Material and Methods Pancreatic EUS-FNBs obtained with the SharkCoreTM FNB were reviewed between January 2014 and June 2019. Specimen characteristics and pathology data including tissue triage were obt...

: BACKGROUND : Endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) has been suggested for obtaining high quality tissue samples from pancreatic tumors. We performed a multicenter randomized crossover trial comparing EUS-FNB with a 20G Procore needle vs. a 22G Acquire needle. The aims were to compare the quantity of targeted tissue (pancreas) and diagnostic accuracy for the two needles. METHODS : 60 patients admitted for EUS-FNB in three endoscopy units were included. One pass was performed...

BACKGROUND AND AIM: Endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) is used to diagnose lesions within or adjacent to the digestive tract. However, there is no report on the overall diagnostic accuracy, technical success, and adverse events of FNB. The aims of this study were to conduct a systematic review and meta-analysis to comprehensively assess the diagnostic accuracy, technical success, and adverse events of FNB. METHODS: Pubmed, Embase, and Cochrane Library databases were search...

Linear echoendoscopes with large instrument channels enable EUS-guided interventions in organs and anatomical spaces in proximity to the gastrointestinal tract. Novel devices and tools designed for EUS-guided transluminal interventions allow various new applications and improve the efficacy and safety of these procedures. New-generation biopsy needles provide higher histology rates and require less passes. Specially designed stents and stent insertion devices enable intra- and extra-hepatic bile...
