Primary sclerosing cholangitis (PSC), a chronic progressive disease of unknown etiology, is characterized by fibrosis and strictures involving the intra- and extrahepatic bile ducts [1, 2]. PSC is a distinct entity from IgG4-related sclerosing cholangitis (IgG4-SC), but some IgG4-SC masquerades as PSC by way of similar manifestations, such as frequent stenosis of both intra- and extrahepatic bile ducts, bile ductal wall thickening, male predominance, cholestatic liver dysfunction, and initial mi...

OBJECTIVE: IgG4-related disease (IgG4-RD) can cause fibroinflammatory lesions in nearly any organ, leading to organ dysfunction and failure. The IgG4-RD Responder Index (RI) was developed to help investigators assess the efficacy of treatment in a structured manner. The aim of this study was to validate the RI in a multinational investigation. METHODS: The RI guides investigators through assessments of disease activity and damage in 25 domains, incorporating higher weights for disease manifestat...

Background and Objectives: Preoperative portal vein (PV) embolization using the percutaneous transhepatic approach has been performed in patients with hepatobiliary malignancy before extensive liver resection. The aim of this study is to evaluate the technical feasibility and initial safety of EUS-guided selective PV embolization using a coil and cyanoacrylate in a live porcine model. Methods: EUS-guided selective intrahepatic PV embolization with a coil and cyanoacrylate was performed in 9 pigs...

Abstract Background/objectives The pancreatoduodenal groove (anatomical groove) is a potential space bordered by the head of the pancreas, duodenum, and common bile duct. Discerning between groove carcinoma (GC) and groove pancreatitis (GP) is often difficult, but clinically important. We retrospectively analyzed and compared the findings of computed tomography (CT), laboratory tests, and endoscopic ultrasound-fine needle aspiration (EUS-FNA) for GC and GP. Methods GC (n = 36) and GP (n = 44) pa...

Background/Aims: Differentially diagnosing focal-type autoimmune pancreatitis (f-AIP) and pancreatic cancer (PC) is challenging. Contrast-enhanced harmonic endoscopic ultrasound (CEH-EUS) may provide information for differentiating pancreatic masses. In this study, we evaluated the usefulness of CEH-EUS in differentiating f-AIP from PC. Methods: Data were collected prospectively and analyzed on patients who underwent CEH-EUS between May 2014 and May 2015. Eighty consecutive patients were diagnos...

Background/Aims: Presence of enhanced mural nodules, which can be visualized using computed tomography (CT), is one of high-risk stigmata in branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs). Conversely, the absence of enhanced mural nodules on preoperative imaging does not exclude malignant risk. The present study aimed to investigate other morphological features as predictors of malignancy in "pure" BD-IPMNs without enhanced mural nodules on CT. Methods: This retrospective study ...

Background and Aims Small hepatic masses often do not have distinct margins on B-mode EUS images. Contrast-enhanced harmonic EUS (CEH-EUS) is widely used for evaluating ambiguous pancreatic lesions. However, its role in detecting hepatic lesions and the use of EUS-guided FNA are not well evaluated. We investigated the usefulness of CEH-EUS–guided FNA for evaluating hepatic lesions. Methods Thirty consecutive patients with hepatic masses underwent CEH-EUS and CEH-EUS–guided FNA between September ...

BACKGROUND AND AIM: Little is known about the standard care of small (<2 cm in diameter) pancreatic neuroendocrine tumors (PNET). The aim of the present study was to determine the clinical outcomes of small PNET after endoscopic ultrasound (EUS)-guided ethanol-lipiodol ablation (EUS-ELA). METHODS: In this prospective cohort study, consecutive patients who underwent EUS-ELA for PNET were enrolled and were followed for ≥3 years. Treatment efficacy was the primary outcome measure. RESULTS: In total...
