BACKGROUND AND AIM Few studies have investigated endoscopic ultrasound-guided fine-needle aspiration with contrast-enhanced harmonic imaging (EUS-FNA-CHI) for diagnosing and adequately sampling pancreatic lesions. This study aimed to investigate the efficacy of EUS-FNA-CHI compared with that of endoscopic ultrasound-guided fine-needle aspiration with fundamental B mode imaging (EUS-FNA-FBI) for diagnosing solid pancreatic lesions. METHODS Consecutive patients with solid pancreatic lesions were e...

BACKGROUND AND AIM Chronic pancreatitis (CP) leads to permanent impairment of exocrine and endocrine functions. The endoscopic ultrasonography (EUS)-based Rosemont classification plays an important role in diagnosing CP. However, it is based on subjective judgment. In contrast, EUS shear wave measurement (EUS-SWM) has been established to be a precise modality for evaluating tissue hardness. This study aimed to evaluate the utility of EUS-SWM in diagnosing CP and determining exocrine and endocrin...

: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is useful in differentiating pancreatic cancer from other pancreatic diseases and allows the collection of histopathological evidence before surgical resection or chemotherapy for pancreatic cancer. Numerous studies have investigated the diagnostic performance of EUS-FNA in pancreatic cancer. A systematic review by Chen et al. demonstrated the high diagnostic performance of EUS-FNA based on a sensitivity of 92% (95% confidence inter...

: The first edition of the guidelines for the use of ultrasound contrast agents was published in 2004, dealing with liver applications. The second edition of the guidelines in 2008 reflected changes in the available contrast agents and updated the guidelines for the liver, as well as implementing some nonliver applications. The third edition of the contrast-enhanced ultrasound (CEUS) guidelines was the joint World Federation for Ultrasound in Medicine and Biology-European Federation of Societies...

PURPOSE: Animal studies of endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) of the liver have rarely been reported. We assessed the effectiveness and safety of EUS-RFA in pigs. METHODS: We conducted four experiments using newly designed RFA electrodes. In the first experiment, we ablated excised liver using 19 G electrodes with active electrode tips with lengths of 1, 1.5, and 2 cm. The second experiment was performed with the same electrodes as those used in the first experiment, ...

BACKGROUND: Peroral cholangioscopy (POCS) of indeterminate biliary strictures aims to achieve a diagnosis through visual examination and/or by obtaining targeted biopsies under direct visualization. In this large, prospective, multinational, real-life experience of POCS-guided evaluation of indeterminate biliary strictures, we evaluated the performance of POCS in this difficult-to-manage patient population. METHODS: This prospective registry enrolled patients, with indeterminate biliary strictur...
