Abstract
OBJECTIVES PSC strictures are routinely diagnosed on T2-MRCP as dominant- (DS) or high-grade stricture (HGS). However, high inter-observer variability limits their utility. We introduce the "potential functional stricture" (PFS) on T1-weighted hepatobiliary-phase images of gadoxetic acid-enhanced MR cholangiography (T1-MRC) to assess inter-reader agreement on diagnosis, location, and prognostic value of PFS on T1-MRC vs. DS or HGS on T2-MRCP in PSC patients, using ERCP as the gold standard. METHODS Six blinded readers independently reviewed 129 MRIs to diagnose and locate stricture, if present. DS/HGS was determined on T2-MRCP. On T1-MRC, PFS was diagnosed if no GA excretion was seen in the CBD, hilum or distal RHD, or LHD. If excretion was normal, "no functional stricture" (NFS) was diagnosed. T1-MRC diagnoses (NFS = 87; PFS = 42) were correlated with ERCP, clinical scores, labs, splenic volume, and clinical events. Statistical analyses included Kaplan-Meier curves and Cox regression. RESULTS Interobserver agreement was almost perfect for NFS vs. PFS diagnosis, but fair to moderate for DS and HGS. Forty-four ERCPs in 129 patients (34.1%) were performed, 39 in PFS (92.9%), and, due to clinical suspicion, five in NFS (5.7%) patients. PFS and NFS diagnoses had 100% PPV and 100% NPV, respectively. Labs and clinical scores were significantly worse for PFS vs. NFS. PFS patients underwent more diagnostic and therapeutic ERCPs, experienced more clinical events, and reached significantly more endpoints (p < 0.001) than those with NFS. Multivariate analysis identified PFS as an independent risk factor for liver-related events. CONCLUSION T1-MRC was superior to T2-MRCP for stricture diagnosis, stricture location, and prognostication. CLINICAL RELEVANCE STATEMENT Because half of PSC patients will develop clinically-relevant strictures over the course of the disease, earlier more confident diagnosis and correct localization of functional stricture on gadoxetic acid-enhanced MRI may optimize management and improve prognostication. KEY POINTS • There is no consensus regarding biliary stricture imaging features in PSC that have clinical relevance. • Twenty-minute T1-weighted MRC images correctly classified PSC patients with potential (PFS) vs with no functional stricture (NFS). • T1-MRC diagnoses may reduce the burden of diagnostic ERCPs.

Abstract
BACKGROUND/AIMS Primary sclerosing cholangitis (PSC) represents the most common hepatobiliary extraintestinal manifestation of inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD). Limited data exist on PSC in patients with IBD from India. We aimed to assess the prevalence and disease spectrum of PSC in Indian patients with IBD. METHODS Database of IBD patients at 5 tertiary care IBD centers in India were analyzed retrospectively. Data were extracted and the prevalence of PSC-IBD was calculated. RESULTS Forty-eight patients out of 12,216 patients with IBD (9,231 UC, 2,939 CD, and 46 IBD unclassified) were identified to have PSC, resulting in a prevalence of 0.39%. The UC to CD ratio was 7:1. Male sex and pancolitis (UC) or colonic CD were more commonly associated with PSC-IBD. The diagnosis of IBD preceded the diagnosis of PSC in most of the patients. Majority of the patients were symptomatic for liver disease at diagnosis. Eight patients (16.66%) developed cirrhosis, 5 patients (10.41%), all UC, developed malignancies (3 colorectal cancer [6.25%] and 2 cholangiocarcinoma [4.16%]), and 3 patients died (2 decompensated liver disease [4.16%] and 1 cholangiocarcinoma [2.08%]) on follow-up. None of the patients mandated surgical therapy for IBD. CONCLUSIONS Concomitant PSC in patients with IBD is uncommon in India and is associated with lower rates of development of malignancies.

Abstract
Autoimmune liver disease is an important immune-mediated pathologic entity involving the liver and intrahepatic bile duct, including autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis. Although it is necessary to ascertain its presence in acute or chronic liver disease without common causes, it is not easy to diagnose this disease straightforwardly because of its rarity. Recently, the incidence and prevalence of autoimmune hepatitis and primary biliary cholangitis have increased in several regions. In contrast, there is limited data dealing with the trend of the epidemiology of primary sclerosing cholangitis worldwide. Physicians should consider the epidemiologic characteristics of autoimmune liver disease because early diagnosis and proper treatment might prevent the progression of advanced liver disease. In addition, more sophisticated epidemiologic studies will be needed to elucidate the trend of these rare diseases nationwide.

Abstract
BACKGROUND Primary sclerosing cholangitis (PSC) is a chronic, progressive liver disease, and many patients ultimately require liver transplantation (LT). PSC also confers an increased risk of malignancies, including cholangiocarcinoma (CCA) and colorectal cancer. AIMS This study aimed to evaluate patient-perceived outcomes and the extent to which these impact health-related quality of life (HRQoL). METHODS Patients with PSC completed a risk perception questionnaire, the Short Form-36 (SF-36), and the Chronic Liver Disease Questionnaire. Multivariable models were used to determine factors associated with patient-perceived risks of malignancy, LT, and life expectancy, as well as their relationship with HRQoL scores. RESULTS A total of 95 patients completed the risk perception questionnaire, and 73 returned the remaining instruments. The estimated risks varied widely. Half overestimated their one-year or lifetime CCA risk, while some predicted zero chance. Predicted LT risk was the only outcome concordant with disease severity. Pruritus was associated with higher predicted one-year risks and lower life expectancy. Lifetime CCA and LT risks were associated with the SF-36 physical component score, while perceived life expectancy was strongly associated with mental health domains, including the SF-36 mental component score. CONCLUSIONS Predicted prognosis varies widely among patients with PSC and is influenced more by symptoms than objective disease severity. The psychological burden of shorter perceived life expectancy impacts mental HRQoL more than the risks of malignancy or LT. These findings highlight an opportunity for improved patient communication regarding these outcomes, as well as the importance of discussing them, as they may impact HRQoL.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic, progressive cholestatic disease that is associated with inflammatory bowel disease (IBD) in approximately 70% of cases. Although the pathogenesis is still unknown for both diseases, there is increasing evidence to indicate that they share a common underlying predisposition. Herein, we review the epidemiology, diagnosis, disease pathogenesis, and specific clinical features of the PSC-IBD phenotype. Patients with PSC-IBD have a distinct IBD phenotype with an increased incidence of pancolitis, backwash ileitis, and rectal sparing. Despite often having extensive colonic involvement, these patients present with mild intestinal symptoms or are even asymptomatic, which can delay the diagnosis of IBD. Although the IBD phenotype has been well characterized in PSC patients, the natural history and disease behavior of PSC in PSC-IBD patients is less well defined. There is conflicting evidence regarding the course of IBD in PSC-IBD patients who receive liver transplantation and their risk of recurrent PSC. IBD may also be associated with an increased risk of cholangiocarcinoma in PSC patients. Overall, the PSC-IBD population has an increased risk of developing colorectal neoplasia compared to the conventional IBD population. Lifelong annual surveillance colonoscopy is currently recommended.

Abstract
Objective: To summarize and review the clinical and genetic features of neonatal sclerosing cholangitis (NSC) caused by DCDC2 variations. Methods: Whole exome sequencing was performed to identify DCDC2 variants in two Chinese siblings with NSC who were diagnosed in Children's Hospital of Fudan University in May 2017. Clinical, laboratory and genetic data of the two cases were summarized. Key words of "DCDC2" "neonatal sclerosing cholangitis" were searched in Chinese databases and PubMed for articles published until April 2018, and all the relevant literature were reviewed. Results: Patient 1 was a 3-year-and-2-month-old boy. He was admitted to our hospital due to cholestasis for 3 years. Laboratory findings showed elevated levels of gamma-glutamyl transpeptidase (161-1 092 U/L) and total cholesterol (5.4-7.7 mmol/L). Magnetic resonance cholangiopancreatography showed multiple dilations of intrahepatic bile ducts and bilateral hydronephrosis. Patient 2, the older brother of patient 1, was a 9-year-and-9-month-old boy. He was admitted to our hospital due to "cholestasis for 9 years" . CT angiography showed hydrocephalus and left internal carotid artery aneurysms with vascular malformations. A homozygous variant c.529dupA (NM_001195610) in DCDC2 gene was identified in patient 1 by whole exome sequencing. Patient 2 was a homozygote and his parents were heterozygotes with the variation. There has been 2 relevant articles published (Chinese 0, English 2), which reported 11 cases of DCDC2-related NSC in total. All the 13 patients, including the 2 cases reported here, had an onset of symptoms at 0 to 6 months of age. The most common clinical manifestation was cholestasis with high gamma-glutamyl transpeptidase levels, acholic stool, and progression to portal hypertension. Renal and neurological abnormalities were also frequently present. Hypercholesterolemia was observed in one case. Radiological findings revealed the characteristic strictures and dilatations of the intrahepatic and (or) extrahepatic biliary tree. Liver histological examination showed peripheral ductopenia, ductal plate malformation, fibrosis, and cirrhosis. Among the 13 patients, 10 patients required liver transplantation. A total of 7 types of DCDC2 variants were detected in 13 patients. Conclusions: DCDC2-related NSC is characterized by the onset of cholestasis with high gamma-glutamyl transpeptidase level and acholic stool in early infancy, which was likely to progress to cirrhosis in early childhood. Renal and neurological abnormalities are also frequently present.Cholangiography or magnetic resonance cholangiopancreatography show strictures and dilatations of the intrahepatic or (and) extrahepatic biliary tree. Identification of pathogenic DCDC2 variants would aid the diagnosis of NSC.

Abstract
Background/Aims Diffuse or segmental irregular narrowing of the main pancreatic duct (MPD), as observed by endoscopic retrograde cholangiopancreatography (ERCP), is a characteristic feature of autoimmune pancreatitis (AIP). Methods ERCP findings were retrospectively examined in 40 patients with AIP in whom irregular narrowing of the MPD was detected near the orifice. The MPD opening sign was defined as the MPD within 1.5 cm from the orifice being maintained. The distal common bile duct (CBD) sign was defined as the distal CBD within 1.5 cm from the orifice being maintained. Endoscopic findings of a swollen major papilla and histological findings of specimens obtained from the major papilla were examined in 26 and 21 patients, respectively. Results The MPD opening sign was detected in 26 of the 40 patients (65%). The distal CBD sign was detected in 25 of the 32 patients (78%), which showed stenosis of the lower bile duct. The patients who showed the MPD opening sign frequently showed the distal CBD sign (p=0.018). Lymphoplasmacytic infiltration, but not dense fibrosis, was histologically detected in biopsy specimens obtained from the major papilla. Conclusions On ERCP, the MPD and CBD adjacent to the major papilla are frequently maintained in patients with AIP involving the pancreatic head. These signs are useful for diagnosing AIP on ERCP.

Abstract
Immunoglobulin G4 (IgG4)-related disease is a novel disease entity that can involve diverse organs, causing specific diseases, including autoimmune pancreatitis, sclerosing cholangitis, cholecystitis, inflammatory aortic aneurysm, and inflammatory pseudotumor. IgG4-related disease is characterized by elevated serum IgG4 concentrations, abundant IgG4 lymphoplasmacytic infiltration, and dramatic steroid responses. It is clinically important to differentiate this rare disease from primary sclerosing cholangitis and cholangiocarcinoma, because the treatment and prognosis of these two diseases are completely different. However, the preoperative diagnosis is challenging, and the disease is frequently misdiagnosed. If the serum level of IgG4 is within the normal range, the diagnosis of IgG4-related disease is more difficult. This article reports on a 59-year-old man with IgG4-related disease mimicking unresectable gallbladder cancer with normal serum IgG4 concentrations.
