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...

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...

AIM: Primary sclerosing cholangitis (PSC) is very rare in Japan. Although a large-scale cohort study of 781 pediatric-onset PSC patients in Europe and North America showed that the 5-year survival with native liver was 88%, the long-term outcomes of pediatric-onset PSC in Japan are unknown. Here, we evaluated the clinical outcomes of pediatric-onset PSC in Japan. METHODS: We carried out a retrospective cohort study with a medical records review of pediatric PSC patients diagnosed between 1986 an...

: We herein report a 49-year-old woman with a perivascular epithelial cell tumor (PEComa) of the pancreas. Imaging studies demonstrated a relatively well-demarcated mass, measuring approximately 40 mm in diameter, located in the pancreatic tail. It was heterogeneously enhanced almost to the same degree as the surrounding pancreatic tissue in both the arterial and portal venous phases. We performed endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) using the Acquire® 22-gauge needle an...

PURPOSE: Since oncological outcomes of transanal colorectal tube (TCT) placement, an endoscopic treatment for colorectal cancer (CRC) with acute colorectal obstruction (ACO), remain unknown, this study analyzed long-term outcomes of TCT placement for stage II/III CRC with ACO. Materials and Methods: Data were retrospectively reviewed from consecutive patients with distal stage II/III CRC who underwent surgery between January 2007 and December 2011 at two Japanese hospitals. One hospital conducte...

: IgG4-related sclerosing cholangitis (IgG4-SC) is a distinct type of cholangitis frequently associated with autoimmune pancreatitis and currently recognized as a biliary manifestation of IgG4-related disease. Although clinical diagnostic criteria of IgG4-SC were established in 2012, differential diagnosis from primary sclerosing cholangitis and cholangiocarcinoma is sometimes difficult. Furthermore, no practical guidelines for IgG4-SC are available. Because the evidence level of most articles r...
