Background Several years have passed since the clinical diagnostic criteria for IgG4-related sclerosing cholangitis 2012 were published. New findings and knowledge have accumulated since then. Methods The Research Committees for IgG4-related Diseases and for Intractable Diseases of the Liver and Biliary Tract in association with the Ministry of Health, Labor and Welfare of Japan and the Japan Biliary Association, have established a working group consisting of researchers specializing in IgG4-SC ...

Abstract Background The clinical characteristics of IgG4-related sclerosing cholangitis (IgG4-SC) especially without autoimmune pancreatitis (AIP) have not been investigated in a large cohort. Aims To clarify the clinical characteristics of IgG4-SC and IgG4-SC without AIP. Methods We retrospectively reviewed imaging, serology, other organ involvement (OOI) and histology of 872 patients with IgG4-SC who participated in a Japanese nationwide survey in 2019, and compared these items between IgG4-SC...

High-grade pancreatic intraepithelial neoplasia (HG PanIN)/carcinoma in situ (CIS) in the pancreatic body and tail can induce parenchymal atrophy through chronic inflammatory changes presenting as a Hypoechoic area on EUS (Hypocho) or focal pancreatic parenchymal atrophy (FPPA) on computed tomography (CT) and magnetic resonance imaging (MRI). We herein discussed two patients with a hypoechoic area in the pancreatic head and neck on EUS resembling pancreatic ductal adenocarcinoma (PDAC). The lesi...

Background and study aims Acute obstructive suppurative pancreatic ductitis (AOSPD) is a suppurative pancreatic duct infection with main pancreatic duct (MPD) or accessory pancreatic duct obstruction in the absence of a pancreatic pseudocyst or necrosis, which is experienced usually in chronic pancreatitis. The diagnosis is confirmed by the finding of pancreatic duct obstruction on endoscopic retrograde cholangiopancreatography (ERCP) with evidence of infection, such as a positive pancreatic jui...

The biopsy-based diagnosis of autoimmune pancreatitis (AIP) is difficult but is becoming imperative for pathologists due to the increased amount of endoscopic ultrasound-guided biopsy tissue. To cope with this challenge, we propose guidance for the biopsy diagnosis of type 1 AIP. This guidance is for pathologists and comprises three main parts. The first part includes basic issues on tissue acquisition, staining, and final diagnosis, and is intended for gastroenterologists as well. The second pa...

Objectives Diagnosing high-grade intraepithelial neoplasia without invasion, traditionally referred to as carcinoma in situ (CIS), is essential for improving prognosis. We examined the imaging findings of patients with and without CIS to identify significant aspects for the diagnosis of CIS. Methods Forty-six patients strongly suspected of early pancreatic cancer without nodule on imaging (CIS group, n = 27; non-malignant group, n = 19) were retrospectively evaluated according to ten factors of ...

BACKGROUND/PURPOSE Epidemiological data on immunoglobulin G4-related sclerosing cholangitis (IgG4-SC) are scarce. METHOD We randomly selected healthcare facilities from a list of all facilities in Japan. The selection rate was determined according to a stratification based on the facility characteristics and scale. We sent questionnaires to the selected facilities enquiring about the number and sex of patients with IgG4-SC in 2018. Among responding facilities, we further inquired about the clini...

Abstract Objectives We examined the efficacy and limitations of acquiring large specimens by endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) for diagnosing type 1 autoimmune pancreatitis (AIP). Methods Patients from 12 institutions with non-neoplastic diseases or pancreatic ductal adenocarcinoma (PDAC) with large EUS-FNB specimens were investigated. Slides stained with hematoxylin-eosin, elastic, IgG4, and IgG stains were evaluated. The IgG4-and IgG-positive cell numbers were counted i...

Serial pancreatic juice aspiration cytologic examination (SPACE) by nasopancreatic tube placement can give us an opportunity to diagnose early-stage pancreatic cancer with higher sensitivity and specificity compared with conventional pancreatic cytology by one-time pancreatic juice aspiration or pancreatic duct brushing. We performed SPACE in a patient with persistent pancreatic duct stricture (PDS) with gradually advancing pancreatic parenchyma atrophy (PPA) in the pancreas tail. The result of ...
