Abstract Background and Aim: This study aimed to determine the clinical characteristics of
immunoglobulin G4 (IgG4)‐associated sclerosing cholangitis (ISC) and provide clinical …

Aims. IgG4-related sclerosing cholangitis in extrahepatic bile ducts in the absence of
autoimmune pancreatitis (AIP) is rare and is poorly studied. Herein, we present the …

Methods We retrospectively compared clinical, serological, imaging, and histological
features of six patients with IgG4-SC and 42 patients with hilar CC. Results In patients with …

Extrahepatic bile ducts are the most commonly involved extrapancreatic organ site in
patients with type 1 autoimmune pancreatitis. IgG4-related sclerosing cholangitis (IgG4-SC) …

Background/purpose IgG4-related sclerosing cholangitis (IgG4-SC) is one of several
diseases associated with autoimmune pancreatitis (AIP). However, diffuse cholangraphic …

Sclerosing cholangitis is heterogeneous in its etiopathogenesis. Recently, sclerosing
cholangitis showing abundant immunoglobulin (Ig) G4+ plasma cell infiltration was added to …

Background The most common cause of perihilar obstruction is cholangiocarcinoma,
especially in Thailand. Benign perihilar stricture represents less than 20% of cases. IgG4 …

Background IgG4-related sclerosing cholangitis (IgG4-SC) needs to be differentiated from
primary sclerosing cholangitis (PSC). In this study, we performed a retrospective study to …

IgG4-related sclerosing cholangitis (IgG4-SC) is often associated with autoimmune
pancreatitis. However, the diffuse cholangiographic abnormalities observed in IgG4-SC may …

Background IgG4-related sclerosing cholangitis (IgG4-SC) needs to be differentiated from
