Abstract
Immunoglobulin G4-related disease (IgG4-RD) is a newly recognized chronic fibro-inflammatory autoimmune disease, and its recognition has been constantly increasing worldwide over the last few years. A correct and timely recognition, as well as appropriate intervention, is crucial for the treatment of IgG4-RD. For certain subtypes of IgG4-RD, organ-specific criteria are formulated to make the diagnosis more accurate. New biomarkers have emerged in the recent years to aid the disease diagnosis, its prognosis prediction, as well as therapy response monitoring. Although recurrence is very common in IgG4-RD, glucocorticoid is still the first-line treatment for the majority of patients. The factors that affect the likelihood of disease relapse are multifaceted. The selection strategy of various steroid-sparing agents is still being explored. Besides, when patients have special sites involvement leading to severe clinical conditions, surgical operation or interventional therapy should also be considered. An update on classification, diagnosis, and management of IgG4-RD is provided in the current study to fully elucidate the recommended clinical practice of this mysterious disease.

Endoscopic biliary stenting as the risk factor for cholangitis after endoscopic ultrasound in patients with biliary strictures. J Gastroenterol Hepatol 2021; 36:1263-1266.

Abstract
BACKGROUND AND AIM Endoscopic ultrasound (EUS) and EUS-guided fine needle aspiration (FNA) are established as efficient and safe diagnostic modalities. However, the risk of cholangitis after EUS/EUS-FNA (post-EUS cholangitis) in patients who have biliary strictures has not been fully examined. METHODS We retrospectively reviewed 136 consecutive inpatients with biliary strictures who received EUS/EUS-FNA at our hospital from April 2012 to September 2017 and evaluated complications that occurred by the next day after EUS/EUS-FNA. Patients with percutaneous biliary drainage, those in whom it was difficult to reach the duodenum, and those receiving concurrent endoscopic retrograde cholangiopancreatography were excluded. RESULTS We included 121 patients (147 cases); 90 patients were malignant. Endoscopic biliary stenting (EBS) with plastic stents had already been performed in 86 cases. Post-EUS cholangitis was observed in 4.1% (6/147). No other EUS-related complications were observed. The incidence of cholangitis with EBS was significantly higher than that in the cases without EBS (7.0% [6/86] vs 0% [0/61], P = 0.042). Biliary enzyme elevation was also identified as a risk factor of cholangitis. CONCLUSION Endoscopic biliary stenting was identified as a risk factor associated with post-EUS cholangitis in patients with biliary strictures. Endoscopists should pay attention to post-EUS cholangitis, especially in cases with EBS and biliary enzyme elevation.

Abstract
IgG4-related disease is an immune-mediated fibroinflammatory condition with a diverse spectrum of organ involvement, commonly in the pancreas and bile ducts among other organs such as salivary and lacrimal glands. Classic histopathologic findings are the gold standard for confirmation of diagnosis, although diagnosis remains challenging, as biomarkers to date are neither sufficient nor necessary. Glucocorticoids are the most effective initial treatment, generally having a dramatic response, although limited clinical evidence exists regarding effective maintenance therapy. This review summarizes key GI manifestations of this condition for the practicing gastroenterologist and addresses the pathology, disease mechanism, and current therapeutic recommendations.

Abstract
An 85-year-old man presented with a pale appearance and generalised pruritic papules. Laboratory investigations disclosed eosinophilia, autoimmune haemolytic anaemia, mixed hyperbilirubinaemia, cholestasis and elevated serum IgG4 levels. Abdominal sonography and CT showed progressive dilatation of biliary trees, with diffuse pancreatic enlargement and a subtle capsule-like low-density rim around the pancreatic head and body. Endoscopic retrograde cholangiopancreatography found no stone-related biliary obstruction, while endoscopic transpapillary biopsy demonstrated chronic inflammation only. Nevertheless, the diagnosis of IgG4-related disease with coexisting autoimmune haemolytic anaemia was presumed. The clinical picture and laboratory abnormalities improved after administration of moderate dose of methylprednisolone.

Abstract
IgG4-related disease (IgG4-RD) is an inflammatory condition characterized by a high serum IgG4 concentration and the abundant infiltration of lymphocytes and IgG4-positive plasma cells in the tissue, as well as spatial (diverse clinical manifestations) and temporal (the possibility of recurrence) multiplicities. Since the initial documentation of IgG4-related disease in patients with autoimmune pancreatitis in 2001, a growing body of evidence has been accumulating to suggest that various-virtually all-organs can be affected by IgG4-RD. In general, steroid therapy is effective and is considered to be the first-line treatment for IgG4-RD. The precise mechanism underlying this systemic disorder has remained unknown. Considering that IgG4-RD was specified as being an intractable disease in 2015, further studies are needed to clarify whether IgG4-RD is indeed a distinct disease entity or a complex of disorders of different etiologies and clinical conditions.

Abstract
Immunoglobulin G4 (IgG4)-related sclerosing cholangitis is a special form of cholangitis. As an autoimmune disease, IgG4-related sclerosing cholangitis has no specific clinical manifestations, and its pathogenesis remains unclear. In patients with this disease, serum concentration of IgG4 is elevated, intrahepatic or extrahepatic bile duct stenosis associated with biliary wall thickening is often revealed by biliary imaging, autoimmune diseases such as autoimmune pancreatitis may be present, and massive IgG4 positive plasma cell infiltration and widespread bile duct wall fibrosis are often showed by histopathological examination. It is often difficult to differentiate IgG4-related sclerosing cholangitis from primary sclerosing cholangitis, secondary sclerosing cholangitis and bile duct cancer. However, the disease is sensitive to hormone therapy. This article will review the current advances in research of IgG4-related sclerosing cholangitis.

Abstract
Immunoglobulin G4-related disease (IgG4-RD) represents a group of disorders that share features of inflammation, plasma cell infiltrates, and fibrosis. Sclerosing cholangitis is a disorder involving inflammation, scarring, and destruction of the bile ducts. IgG4-related sclerosing cholangitis (IgG4-SC) has been proposed as a bile duct lesion associated with IgG4-RD. This disease entity can be distinguished from other types of sclerosing cholangitis and classified into four types based upon the region of strictures revealed by cholangiography. Here, we present two cases in which the finding of bile duct wall thickening visualized with transabdominal ultrasonography was useful in the diagnosis of patients with IgG4-SC. At present, transabdominal ultrasonography is not included in the diagnostic algorithm for IgG4-SC. We are certain that detailed observation of the bile duct wall with transabdominal ultrasonography can make a significant contribution to the diagnosis of IgG4-SC. Furthermore, we propose that transabdominal ultrasonography may be useful in following clinical improvement in cases where a steroid trial is the best option for treatment. Both cases emphasize the practicality of transabdominal ultrasonography in the diagnosis and follow-up observation of IgG4-SC.

Abstract
PURPOSE Response to steroids is included in the diagnostic criteria for IgG4-related sclerosing cholangitis (IgG4-SC). To assess how to appropriately conduct steroid trials for IgG4-related SC, we examined the clinical pictures of steroid responsiveness in IgG4-SC patients. MATERIAL AND METHODS A total of 29 patients with IgG4-SC (lower bile duct involvement, n=29; hilar/intrahepatic bile duct involvement, n=6) initially treated with steroids were enrolled in this study. Blood biochemistry was examined at about 5, 10 and 15 days after commencing steroid therapy. Endoscopic retrograde cholangiography (ERC) and magnetic resonance cholangiopancreatography (MRCP) were performed after steroid administration in 18 and 25 patients, respectively. RESULTS In 19 patients without biliary drainage, elevated serum levels of total bilirubin, alanine aminotransferase, and alkaline phosphatase were halved in 50%, 25%, and 44% of patients at about 5 days after starting steroids, and in 17%, 38%, and 44% at about 10 days. Responsiveness to steroids could be evaluated at 1-2 weeks on ERC or MRCP, but response was lower in the hilar/intrahepatic bile duct than in the lower bile duct. CONCLUSIONS Steroid responsiveness of IgG4-SC is recommended to be assessed by blood biochemistry at 5 and 10 days and on MRCP and/or ERC at 1-2 weeks after starting steroid.

Abstract
Since the earliest reports in 2001, immunoglobulin G4 (IgG4)-related disease has been defined as an autoimmune systemic disease characterized by the lymphoplasmacytic infiltration of affected tissues leading to fibrosis and obliterative phlebitis along with elevated serum IgG4 levels. Prior to this unifying hypothesis, a plethora of clinical manifestations were considered as separate entities despite the similar laboratory profile. The pathology can be observed in virtually all organs and may thus be a challenging diagnosis, especially when the adequate clinical suspicion is not present or when obtaining a tissue biopsy is not feasible. Nonetheless, the most frequently involved organs are the pancreas and exocrine glands but these may be spared. Immunosuppressants lead to a prompt clinical response in virtually all cases and prevent histological sequelae and, as a consequence, an early differential diagnosis from other conditions, particularly infections and cancer, as well as an early treatment should be pursued. We describe herein two cases in which atypical disease manifestations were observed, i.e., one with recurrent neck lymph node enlargement and proptosis, and one with jaundice. Our understanding of the pathogenesis of IgG4-related disease is largely incomplete but data support a significant role for Th2 cytokines with the contribution of innate immunity factors such as Toll-like receptors, macrophages and basophils. Further, macrophages activated by IL4 overexpress B cell activating factors and contribute to chronic inflammation and the development of fibrosis. We cannot rule out the possibility that the largely variable disease phenotypes reflect different pathogenetic mechanisms and the tissue microenvironment may then contribute to the organ involvement.

Abstract
IgG4-related disease is a protean condition that mimics many malignant, infectious, and inflammatory disorders. This multi-organ immune-mediated condition links many disorders previously regarded as isolated, single-organ diseases without any known underlying systemic condition. It was recognised as a unified entity only 10 years ago. Histopathology is the key to diagnosis. The three central pathology features of IgG4-related disease are lymphoplasmacytic infiltration, storiform fibrosis, and obliterative phlebitis. The extent of fibrosis is an important determinant of responsiveness to immunosuppressive therapies. IgG4-related disease generally responds to glucocorticoids in its inflammatory stage, but recurrent or refractory cases are common. Important mechanistic insights have been derived from studies of patients treated by B-cell depletion. Greater awareness of this disease is needed to ensure earlier diagnoses, which can prevent severe organ damage, disabling tissue fibrosis, and even death. Identification of specific antigens and T-cell clones that drive the disease will be the first steps to elucidate the pathogenesis of IgG4-related disease.

Abstract
Cholangiocarcinoma is the most common primary malignancy of the bile ducts which has several predisposing factors such as hepatolithiasis and primary sclerosing cholangitis, and can develop from precancerous conditions such as biliary intraepithelial neoplasia and intraductal papillary neoplasm of the bile duct. As surgical resection of early stage cholangiocarcinoma or precancerous lesions may provide better prognosis, early detection of those lesions is very important. Imaging studies play important roles in the diagnosis of bile duct tumors followed by appropriate management. Indeed, not only diagnosis of cholangiocarcinoma but also appropriate categorization of bile duct tumors based on their morphologic features and location on cross-sectional imaging studies, including computed tomography and magnetic resonance imaging, is important to predict their biologic behaviors, and choose relevant treatment strategies. We herein review the classification system of the bile duct tumors with their radiologic and pathologic findings as well as role of imaging in the early detection of bile duct tumors.

Abstract
BACKGROUND Obliterative phlebitis is a useful pathological finding for the diagnosis of lymphoplasmacytic sclerosing pancreatitis (LPSP), or type 1 autoimmune pancreatitis. The present study evaluated histological findings of obliterative phlebitis, including the significance of adding Elastica van Gieson stain (EVG) in comparison with other pancreatic conditions. METHODS Specimens of LPSP (n = 18), chronic pancreatitis (CP; n = 24), and pancreatic ductal adenocarcinoma (PDA; n = 45) were enrolled. Obliterative venous lesions (OVLs), defined as the presence of inflammatory cells and/or fibrosis inside the tunica adventitia, were counted and compared between hematoxylin and eosin stain (H&E) and EVG. OVLs were classified into three types: OVL-1, lymphoplasmacytic infiltration and fibrosis against a loose textured background; OVL-2, dense fibrosis with minimal or no lymphoplasmacytic infiltration; and OVL-3, densely packed lymphoplasmacytic infiltration without fibrosis. OVL type and OVL size were compared between disease groups. RESULTS OVL counts in LPSP, CP, and PDA were significantly higher with EVG than with H&E (p < 0.001). OVL-1 was most common in LPSP (H&E 92.4 %, EVG 79.8 %), and was identified in almost all cases of LPSP, but was less common in CP and PDA. Maximum diameter and OVL count in 1 cm(2) of OVL-1 were high for LPSP. Maximum diameter of OVL-1 ≥150 μm was observed in 17 LPSP, 0 CP, and 1 PDA cases (sensitivity 94.4 %, specificity 98.6 %). CONCLUSIONS Additional EVG is useful for excluding conditions mimicking OVL-1 or detecting OVL in small specimens. The presence of OVL-1 with diameter ≥150 μm is highly diagnostic for LPSP.

Abstract
Although hilar cholangioma is the most common cause of stricture of the hilar bile duct, several diseases can contribute to stenosis. Here, we report on a patient with immunoglobulin (Ig) G4-related sclerosing cholangitis (IgG4-SC) of the hilar bile duct arising from obstructive jaundice. The patient had undergone laparoscopic cholecystectomy for the removal of gallstones. The differential diagnosis for icterus included hilar cholangiocarcinoma, primary sclerosing cholangitis, IgG4 sclerosing cholangitis, ischemic bile duct stenosis, a complication of cholecystitis, amputation neuroma, and iatrogenic stenosis. Numerous examinations were performed, but a definite diagnosis remained elusive. Because cholangiocarcinoma could not be ruled out, we proposed surgical resection. The patient subsequently underwent extended right liver lobectomy and intrahepatic cholangiojejunostomy. Pathological examination revealed numerous inflammatory cell infiltrates resembling IgG4-positive antibody plasma cells in the stromal layer of the stenotic bile duct walls. Hypertrophy of the nerve fiber fascicles was not observed. The serum IgG4 level of the patient was within the normal range. Few reports of IgG4-SC with a normal serum IgG4 level have been published. When this condition presents as it did in the present case, establishing a definite diagnosis can be difficult.

Abstract
Background/Aims Few studies have differentiated immunoglobulin G (IgG) 4-related sclerosing cholangitis (IgG4-SC) from hilar cholangiocarcinoma (CC). Thus, we sought to investigate useful features for differentiating IgG4-SC from hilar CC. 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 hilar CC, obstructive jaundice was more frequent (p<0.01), serum total bilirubin levels were significantly higher (p<0.05), serum CA19-9 levels were significantly higher (p<0.01), and serum duke pancreatic monoclonal antigen type 2 levels were frequently elevated (p<0.05). However, in patients with IgG4-SC, the serum IgG (p<0.05) and IgG4 (p<0.01) levels were significantly higher and frequently elevated. The pancreas was enlarged in all IgG4-SC patients but only in 17% of hilar CC patients (p<0.01). Salivary and/or lacrimal gland swelling was detected in only 50% of IgG4-SC patients (p<0.01). Endoscopic retrograde cholangiography revealed that the hilar or hepatic duct was completely obstructed in 83% of hilar CC patients (p<0.01). Lower bile duct stenosis, apart from hilar bile duct stenosis, was more frequent in IgG4-SC patients (p<0.01). Bile duct wall thickening in areas without stenosis was more frequent in IgG4-SC patients (p<0.01). Conclusions An integrated diagnostic approach based on clinical, serological, imaging, and histological findings is necessary to differentiate IgG4-SC from hilar CC.

Abstract
BACKGROUND IgG4-sclerosing cholangitis (IgG4-SC) patients have an increased level of serum IgG4, dense infiltration of IgG4-positive plasma cells with extensive fibrosis in the bile duct wall, and a good response to steroid therapy. However, it is not easy to distinguish IgG4-SC from primary sclerosing cholangitis, pancreatic cancer, and cholangiocarcinoma on the basis of cholangiographic findings alone because various cholangiographic features of IgG4-SC are similar to those of the above progressive or malignant diseases. METHODS The Research Committee of IgG4-related Diseases and the Research Committee of Intractable Diseases of Liver and Biliary Tract in association with the Ministry of Health, Labor and Welfare, Japan and the Japan Biliary Association have set up a working group consisting of researchers specializing in IgG4-SC, and established the new clinical diagnostic criteria of IgG4-SC 2012. RESULTS The diagnosis of IgG4-SC is based on the combination of the following 4 criteria: (1) characteristic biliary imaging findings, (2) elevation of serum IgG4 concentrations, (3) the coexistence of IgG4-related diseases except those of the biliary tract, and (4) characteristic histopathological features. Furthermore, the effectiveness of steroid therapy is an optional extra diagnostic criterion to confirm accurate diagnosis of IgG4-SC. CONCLUSION These diagnostic criteria for IgG4-SC are useful in practice for general physicians and other nonspecialists.

Abstract
Discrimination between benign and malignant biliary strictures is difficult, with 5.2 to 24.5 per cent of biliary strictures proving to be benign after histological examination of the resected specimen. This study aimed to evaluate the clinicopathological features of benign biliary strictures in patients undergoing resection for presumed biliary malignancy. From January 1990 to August 2010, 5 of 153 (3.3%) patients who had undergone resection after a preoperative diagnosis of biliary malignancy had a final histological diagnosis of benign biliary stricture. The infiltration of immunoglobulin G4-positive plasma cells was evaluated by immunohistochemistry. None of the five patients had a history of trauma or earlier hepatobiliary surgery and all five underwent hemihepatectomy (combined with extrahepatic bile duct resection in three patients). Postoperative morbidity was recorded in two patients (transient cholangitis and biliary fistula), but there was no postoperative mortality. Histological re-examination identified immunoglobulin G4-related sclerosing cholangitis (n = 2) and nonspecific fibrosis/inflammation (n = 3). No preoperative clinical or radiographic features were identified that could reliably distinguish patients with benign biliary strictures from those with biliary malignancies. Although benign biliary strictures are rare, differentiating benign strictures from malignancy remains problematic. Thus, the treatment approach for biliary strictures should remain surgical resection for presumed biliary malignancy.

Abstract
Immunoglobulin G4-related sclerosing cholangitis (IgG4-SC) is a recently defined disease entity characterized by elevated serum IgG4, chronic progressive obstructive jaundice, and diffuse or mass-forming inflammatory reaction rich in IgG4-positive plasma cells and lymphocytes associated with fibrosclerosis and obliterative phlebitis, which shares a number of clinical, biochemical, and radiological features with primary sclerosing cholangitis (PSC) or cholangiocarcinoma (CC). IgG4-SC is commonly associated with autoimmune pancreatitis (AIP). Steroid therapy comprises the mainstay of treatment for IgG4-SC patients. However, liver transplantation is the only useful treatment for PSC patients, and CC patients require surgical therapy. Therefore, the accurate discrimination between IgG4-SC and PSC or CC is a very important issue. In this article, we will review the features and role of immunoglobulin G4 (IgG4), the diagnosis and therapy of IgG4-SC, and the relations between IgG4-SC and AIP, PSC or CC.

Abstract
A 68-year-old male patient was referred to our institution in May 2011 for a suspected tumor in the pancreatic head with consecutive jaundice. Using magnetic resonance imaging, further differentiation between chronic inflammation and a malignant process was not possible with certainty. Apart from cholestasis, laboratory studies showed increased values for CA 19-9 to 532 U/ml (normal <37 U/ml) and hypergammaglobulinemia (immunoglobulin G, IgG) of 19.3% (normal 8.0–15.8%) with an elevation of the IgG4 subtype to 2,350 mg/l (normal 52–1,250 mg/l). Endoscopic retrograde cholangiopancreatography revealed a prominent stenosis of the distal ductus hepaticus communis caused by pancreatic head swelling and also a bihilar stenosis of the main hepatic bile ducts. Cytology demonstrated inflammatory cells without evidence of malignancy. Under suspicion of autoimmune pancreatitis with IgG4-associated cholangitis, immunosuppressive therapy with steroids and azathioprine was started. Follow-up endoscopic retrograde cholangiopancreatography after 3 months displayed regressive development of the diverse stenoses. Jaundice had disappeared and blood values had returned to normal ranges. Moreover, no tumor of the pancreatic head was present in the magnetic resonance control images. Due to clinical and radiological similarities but a consecutive completely different prognosis and therapy, it is of fundamental importance to differentiate between pancreatic cancer and autoimmune pancreatitis. Especially, determination of serum IgG4 levels and associated bile duct lesions induced by inflammation should clarify the diagnosis of autoimmune pancreatitis and legitimate immunosuppressive therapy.

Abstract
INTRODUCTION Autoimmune pancreatitis (AIP) is a newly developed concept for a peculiar type of pancreatitis, and at present is recognized as a pancreatic lesion reflecting IgG4-related systemic disease. It is of utmost importance to differentiate AIP from pancreatic cancer to avoid unnecessary surgery. AREAS COVERED The current management strategies for AIP, including its clinical features, diagnostic criteria, clinical subtypes, steroid therapy and prognosis are discussed, based on our 66 AIP cases and papers searched in PubMed from 1992 to March 2011, using the term 'autoimmune pancreatitis'. A new clinicopathological entity, an 'IgG4-related sclerosing disease' is also mentioned. EXPERT OPINION AIP should be considered in the differential diagnosis in elderly male patients presented with obstructive jaundice and pancreatic mass. Steroids are a standard therapy for AIP, but their regimen including maintenance therapy should be evaluated in prospective trials.

Abstract
Acute cholangitis is a potentially life-threatening systemic disease resulting from a combination of infection and obstruction of the biliary tree, secondary to different underlying etiologies. Common causes of cholangitis (eg, gallstones, benign and malignant biliary strictures) are well known. However, others (eg, immunoglobulin-G subclass-4-related sclerosing cholangitis) have been described only recently, are still under evaluation, and need to gain broader attention from clinicians. The diagnosis of acute cholangitis is based on clinical presentation and laboratory data indicating systemic infection, as well as diagnostic imaging modalities revealing signs of biliary obstruction and possibly an underlying etiology. The clinical presentation varies, and initial risk stratification is important to guide further management. Early medical therapy, including fluid resuscitation and appropriate antibiotic coverage, is of major importance in all cases, followed by a biliary drainage procedure and, if possible, definitive therapy of the underlying etiology. The type and timing of biliary drainage should be based on the severity of the clinical presentation, and the availability and feasibility of drainage techniques, such as endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC), and open surgical drainage. ERCP plays a central role in the management of biliary obstruction in patients with acute cholangitis. Endoscopic ultrasound-guided biliary drainage recently emerged as a possible alternative to PTC for second-line therapy if ERCP fails or is not possible.
