Important advancements in endoscopic ultrasound-guided tissue sampling techniques and development of new needle designs have improved the diagnostic yield of pancreatic lesions. This innovation in endoscopic ultrasound has also opened the door for early diagnosis and precision therapy in the management of cancer patients. Endoscopic ultrasound fine needle biopsy is an invaluable tool and newer biopsy designs will probably play a pivotal role in the management of pancreatic lesions in the next future. Aim of the current review is to provide an overview on the available techniques and devices for the endoscopic ultrasound-guided sampling of pancreatic solid and cystic lesions.
BACKGROUND: Cirrhotic patients are at increased risk of adverse events (AEs) after invasive procedures. However, the safety profile of endoscopic ultrasound (EUS) fine-needle aspiration in cirrhotic patients is still unknown. OBJECTIVES: To examine the AEs rate after EUS fine-needle aspiration in cirrhotic patients as compared to a control group of noncirrhotic patients. METHODS: Out of 735 patients with suspected abdominal lesions referred to our center between 2006 and 2018, after propensity-s...
Abstract Background and Aims There is limited evidence on the diagnostic performance of endoscopic ultrasound-guided fine-needle biopsy in patients with subepithelial lesions. Aim of this meta-analysis was to compare EUS-guided fine-needle biopsy performance to fine-needle aspiration in patients with GI subepithelial lesions. Methods Computerized bibliographic search on the main databases was performed through May 2019. Primary endpoint was sample adequacy. Secondary outcomes were diagnostic acc...

Abstract Background and Aims Variable diagnostic performance of sampling techniques during EUS-guided tissue acquisition of solid pancreatic masses based on needle type [fine-needle aspiration (FNA) versus fine-needle biopsy (FNB)] and gauge (19-gauge vs 22-gauge vs 25-gauge) has been reported. We performed a systematic review with network meta-analysis to compare the diagnostic accuracy of EUS-guided techniques for sampling solid pancreatic masses. Methods Through a systematic literature review...
Abstract Background and Aims The recent development of microforceps for endoscopic ultrasound (EUS) through-the-needle biopsy (TTNB) of the wall of pancreatic cystic lesions (PCLs) allows to acquire histological specimens, which pathologists never handled and evaluated before. We aimed to estimate the interobserver agreement among pathologists in evaluating such samples. Methods TTNB slides from 40 PCLs with worrisome features were retrieved and independently evaluated for specimen adequacy, pre...
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 en...
Background and Aims Contrast-enhanced EUS (CE-EUS) allows qualitative and quantitative evaluation based on real-time perfusion imaging and may improve the diagnostic capability. The aim of this study was to evaluate the efficacy of CE-EUS in differentiating malignant from benign lymphadenopathy. Methods Patients undergoing EUS-FNA for abdominal or mediastinal lymphadenopathy were prospectively enrolled. The echofeatures on B-mode EUS and the vascular and enhancement patterns in CE-EUS were quali...
Background In spite of the weak evidence, antibiotic prophylaxis prior to endoscopic ultrasound-guided fine-needle aspiration of pancreatic cystic lesions is routinely used in the clinical practice.
Background The aim of this prospective multicenter study was to compare a flexible 19 G needle with nitinol shaft (19 G Flex) with a standard 22 G needle for transduodenal endoscopic ultrasound (EUS)-guided sampling of pancreatic head tumors. Methods Patients with pancreatic head tumors requiring tissue diagnosis were randomized into two arms: puncture with either a 19 G Flex needle or a 22 G needle. The primary end point was diagnostic accuracy for malignancy. The secondary end points were ergo...
Background and Objective: Robust data in favor of clear superiority of 22G fine-needle biopsy (FNB) over 22G FNA for an echoendoscopic-guided sampling of pancreatic masses are lacking. The objective of this study is to compare the diagnostic outcomes and sample adequacy of these two needles. Materials and Methods: Computerized bibliographic search on the main databases was performed and restricted to only randomized controlled trials. Summary estimates were expressed regarding risk ratio (RR) an...
EUS-guided tissue acquisition technique plays an essential role for evaluation of gastrointestinal tumors. Several components affect the yield of EUS-guided tissue acquisition outcomes such as sampling techniques, use of ROSE (rapid onsite evaluation), training and experience, and needle designs. In this review we discuss advancement in EUS-guided fine needle sampling.

OBJECTIVES It is still unclear whether endoscopic ultrasound (EUS) contrast-enhanced fine-needle aspiration (CH-EUS-FNA) determines superior results in comparison to standard EUS-FNA in tissue acquisition of pancreatic masses. Aim of this meta-analysis was to compare the diagnostic outcomes of these two techniques. METHODS We searched the PubMed/Medline and Embase database through October 2020 and identified 6 studies, of which 2 randomized controlled trials (recruiting 701 patients). We perform...
Background: Whether endoscopic ultrasound (EUS) contrast-enhanced fine-needle aspiration (CH-EUS-FNA) determines superior results in comparison to standard EUS-FNA in tissue acquisition of pancreatic masses remains unclear. The aim of this study was to compare these two techniques on a series of patients with solid pancreatic lesions. Methods: 362 patients underwent EUS-FNA (2008–2019), after the propensity score matching of two groups were compared; 103 treated with CH-EUS-FNA (group 1) and 103...
In spite of promising preliminary results, evidence supporting the use of non-anesthesiologist-administered propofol sedation (NAAP) in endoscopic ultrasound (EUS) procedures is still limited. The aim of this manuscript was to examine the safety and efficacy of NAAP as compared to anesthesiologist-administered propofol sedation in EUS procedures performed in a referral center. Out of 832 patients referred to our center between 2016 and 2019, after propensity score matching two groups were compar...
