Abstract Background and aims The aim of this study was to compare the performance of EUS-guided fine-needle biopsy using fork-tip (SharkCore, Medtronic, USA) or side-fenestrated (ProCore, Cook Medical, Limerick, Ireland) needles in patients with solid pancreatic lesions. Methods This is a randomized controlled study conducted in a single academic center, including patients who underwent sampling with the fork-tip or the side-fenestrated 22-gauge or 25-gauge needles. Three passes were performed, which were each independently evaluated by a blinded pathologist and by endosonographers for macroscopic on-site evaluation (MOSE). The primary outcome was histological yield, whereas secondary aims were safety, diagnostic yield, sample quality, number of needle passes required to establish a diagnosis, and reliability of MOSE. Results One hundred ninety-two patients were enrolled. Both 22-gauge and 25-gauge fork-tip needles retrieved significantly higher rates of histological samples compared with side-fenestrated (p Conclusions Both needles showed equivalent safety and diagnostic accuracy. However, fork-tip needles provided higher rate of extremely good quality histological samples and required fewer needle passes to reach a diagnosis. MOSE is a highly reliable tool when fork-tip needles are used as compared with side-fenestrated needles. ClinicalTrial.gov number NCT03622229

Background and Objectives: Despite rarely, serous cystic adenoma (SCA) can assume a pseudo-solid aspect mimicking other pancreatic neoplasm as neuroendocrine tumor. EUS-FNA cytology has low diagnostic accuracy due to the scant cellularity of the collected samples. Histological diagnosis is usually made after resection. Recently, end-cutting needles for EUS-fine-needle biopsy (EUS-FNB), which obtain tissue cores by penetrating the lesions, have been developed. We aimed to assess the capability of...

Abstract Background Rapid on-site evaluation (ROSE) of cytological specimensacquired with EUS-guided fine needle aspiration (EUS-FNA) represents the most accurate available technique to reach a definitive diagnosis in patients with pancreatic solid masses. Recently, needles with high histological yield have been developed for EUS-guided fine needle biopsy (EUS-FNB), with which the need for ROSE can be potentially overcome. Aims The primary aim is to compare the diagnostic accuracy of EUS-FNB wit...

OBJECTIVES: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the gold standard for the diagnosis of solid pancreatic lesions (SPLs). Cytological samples can also be obtained using touch imprint cytology (TIC) on EUS fine-needle biopsy (FNB) specimens. We aimed to compare sample quality and diagnostic yield of EUS-FNA-standard cytology (EUS-FNA-SC) to that of EUS-FNB-TIC in a series of patients with SPLs. METHODS: Thirty-two consecutive patients referred for EUS-tissue acquisition...

Pancreatic fibrosis is caused by the excessive deposits of extracellular matrix (ECM) and collagen fibers during repeated necrosis to repair damaged pancreatic tissue. Pancreatic fibrosis is frequently present in chronic pancreatitis (CP) and pancreatic cancer (PC). Clinically, pancreatic fibrosis is a pathological feature of pancreatitis and pancreatic cancer. However, many new studies have found that pancreatic fibrosis is involved in the transformation from pancreatitis to pancreatic cancer. ...

Histopathological diagnosis of pancreatic ductal adenocarcinoma (PDAC) on endoscopic ultrasonography-guided fine-needle biopsy (EUS-FNB) specimens has become the mainstay of preoperative pathological diagnosis. However, on EUS-FNB specimens, accurate histopathological evaluation is difficult due to low specimen volume with isolated cancer cells and high contamination of blood, inflammatory and digestive tract cells. In this study, we performed annotations for training sets by expert pancreatic p...

Currently, endoscopic ultrasound (EUS) has become widely accepted and has considerable advantages over computed tomography (CT) and other imaging modalities, given that it enables echostructure assessment in lesions with <1 cm diameter and permits high resolution imaging. EUS-guided tissue acquisition (EUS-TA) provides consistent results under ultrasound guidance and has been considered more effective compared to CT- or ultrasound-guided lesion biopsy. Moreover, complication rates, including pan...

The prognosis of patients with solid tumours has remarkably improved with the development of molecular-targeted drugs and immune checkpoint inhibitors. However, the improvements in the prognosis of pancreatic cancer and biliary tract cancer is delayed compared to other carcinomas, and the 5-year survival rates of distal-stage disease are approximately 10 and 20%, respectively. However, a comprehensive analysis of tumour cells using The Cancer Genome Atlas (TCGA) project has led to the identifica...

Type 1 autoimmune pancreatitis (AIP) is histologically characterized by lymphoplasmacytic sclerosing pancreatitis (LPSP). Recently, the diagnostic yield of endoscopic ultrasonography-guided fine needle aspiration/biopsy (EUS-FNA/B) for AIP has been reported. However, its role in the diagnostic flow of AIP is not fully elucidated. We retrospectively reviewed 53 consecutive patients who were suspected with AIP and underwent EUS-FNA/B. We evaluated the contribution of EUS-FNA/B to the diagnosis of ...
