Abstract
Background Biliary stricture caused by malignant tumors is known as Malignant Biliary Stricture (MBS). MBS is challenging to differentiate clinically, and accurate diagnosis is crucial for patient prognosis and treatment. This study aims to identify the risk factors for malignancy in all patients diagnosed with biliary stricture by Endoscopic Retrograde Cholangiopancreatography (ERCP), and to develop an effective clinical predictive model to enhance diagnostic outcomes. Methodology Through a retrospective study, data from 398 patients diagnosed with biliary stricture using ERCP between January 2019 and January 2023 at two institutions: the First People's Hospital affiliated with Jiangsu University and the Second People's Hospital affiliated with Soochow University. The study began with a preliminary screening of risk factors using univariate regression. Lasso regression was then applied for feature selection. The dataset was divided into a training set and a validation set in an 8:2 ratio. We analyzed the selected features using seven machine learning algorithms. The best model was selected based on the Area Under the Receiver Operating Characteristic (ROC) Curve (AUROC) and other evaluation indicators. We further evaluated the model's accuracy using calibration curves and confusion matrices. Additionally, we used the SHAP method for interpretability and visualization of the model's predictions. Results RF model is the best model, achieved an AUROC of 0.988. Shap result indicate that age, stricture location, stricture length, carbohydrate antigen 199 (CA199), total bilirubin (TBil), alkaline phosphatase (ALP), (Direct Bilirubin) DBil/TBil, and CA199/C-Reactive Protein (CRP) were risk factors for MBS, and the CRP is a protective factor. Conclusion The model's effectiveness and stability were confirmed, accurately identifying high-risk patients to guide clinical decisions and improve patient prognosis.

Diagnostic and predictive ability of hyperbilirubinemia severity in cats: A multicenter retrospective study. J Vet Intern Med 2024; 38:1043-1050. [PMID: 38361342 PMCID: PMC10937506 DOI: 10.1111/jvim.17005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Accepted: 01/24/2024] [Indexed: 02/17/2024] Open
Abstract
BACKGROUND Total serum bilirubin concentration (TBIL) can provide useful information on several pathophysiological conditions in cats. Nevertheless, whether the variable severity classification of hyperbilirubinemia can reliably indicate certain disease processes or predict a biliary obstruction (BO) has not been investigated. HYPOTHESIS/OBJECTIVE Determine if hyperbilirubinemia of variable severity can assist clinicians to identify BO, which often is considered a surgical emergency. ANIMALS Two-hundred sixteen client-owned cats. METHODS Data were retrospectively collected from all cats (January 2015-August 2022) with an increased TBIL (>0.58 mg/dL [>10 μmol/L]) presented to 3 referral centers in the United Kingdom (UK). Presenting clinical features and diagnostic outcomes were collected. The predictive ability of TBIL to indicate BO was evaluated by multivariable binary logistic regression modeling and receiver operating characteristic (ROC) curves. RESULTS Median TBIL was 1.73 mg/dL (range, 0.59-26.15; 29.5 μmol/L; range, 10.1-447.1) with severity classification of hyperbilirubinemia categorized as mild (>0.58-2.92 mg/dL; >10-50 μmol/L; 68.1%), moderate (>2.92-5.85 mg/dL; >50-100 μmol/L; 17.6%), severe (>5.85-11.70 mg/dL; >100-200 μmol/L; 9.7%) and very severe (>11.70 mg/dL; >200 μmol/L; 4.6%). Biliary obstruction was present in 17 (7.9%) cats, all of which received recommendation for emergency surgery. Median TBIL in cats with BO (9.69 mg/dL; 165.7 μmol/L) differed significantly from those without obstruction (1.51 mg/dL; 25.8 μmol/L; P < .01). The optimal TBIL cut-off to discriminate between cats with and without BO was ≥3.86 mg/dL (≥66 μmol/L) with a sensitivity of 94.1% and specificity of 82.4%. Using multivariable logistic regression, as age increased, the odds of BO increased significantly (odds ratio, 1.20; 95% confidence interval, 1.01-1.42; P = .04). CONCLUSIONS AND CLINICAL IMPORTANCE As part of a thorough clinical assessment, the severity classification of hyperbilirubinemia has the potential to predict the likelihood of a BO and to discriminate between cats that may or may not require surgery for BO at a suggested cut-off of ≥3.86 mg/dL (≥66 μmol/L). Alongside TBIL, age is also useful when assessing for the likelihood of BO in a cat presented with hyperbilirubinemia.

Anal Chim Acta 2023; 1239:340678.

Abstract
Bilirubin is an indispensable biomarker for liver diseases. Utilizing organic molecules as sensor platform for effective detection of bilirubin are little. In addition, the reported fluorophores required longer incubation time for detection. Hence, herein we have attempted to design an imidazole derivative 4-(3H-imidazo[4,5-b]pyridin-2-yl)-N,N-diphenylaniline (IMI) from triphenylamine and pyridine units which could detect bilirubin swiftly without any incubation period. IMI manifested an instant quenching of emission in presence of bilirubin with limit of detection (LOD) 11.74 × 10-6 mol L-1. The mechanistic aspect of detection involves coexistence of both static and dynamic quenching which was suitably justified. Finally, the pragmatic application of IMI was performed in bio-fluids.

Gastroenterology Res 2022; 15:240-252. [PMID: 36407811 PMCID: PMC9635785 DOI: 10.14740/gr1560] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Accepted: 09/14/2022] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Current choledocholithiasis guidelines heavily focus on patients with low or no risk, they may be inappropriate for populations with high rates of choledocholithiasis. We aimed to develop a predictive scoring model for choledocholithiasis in patients with relevant clinical manifestations. METHODS A multivariable predictive model development study based on a retrospective cohort of patients with clinical suspicion of choledocholithiasis was used in this study. The setting was a 700-bed public tertiary hospital. Participants were patients who had completed three reference tests (endoscopic retrograde cholangiography, magnetic resonance cholangiopancreatography, and intraoperative cholangiography) from January 2019 to June 2021. The model was developed using logistic regression analysis. Predictor selection was conducted using a backward stepwise approach. Three risk groups were considered. Model performance was evaluated by area under the receiver operating characteristic curve, calibration, classification measures, and decision curve analyses. RESULTS Six hundred twenty-one patients were included; the choledocholithiasis prevalence was 59.9%. The predictors were age > 55 years, pancreatitis, cholangitis, cirrhosis, alkaline phosphatase level of 125 - 250 or > 250 U/L, total bilirubin level > 4 mg/dL, common bile duct size > 6 mm, and common bile duct stone detection. Pancreatitis and cirrhosis each had a negative score. The sum of scores was -4.5 to 28.5. Patients were categorized into three risk groups: low-intermediate (score ≤ 5), intermediate (score 5.5 - 14.5), and high (score ≥ 15). Positive likelihood ratios were 0.16 and 3.47 in the low-intermediate and high-risk groups, respectively. The model had an area under the receiver operating characteristic curve of 0.80 (95% confidence interval: 0.76, 0.83) and was well-calibrated; it exhibited better statistical suitability to the high-prevalence population, compared to current guidelines. CONCLUSIONS Our scoring model had good predictive ability for choledocholithiasis in patients with relevant clinical manifestations. Consideration of other factors is necessary for clinical application, particularly regarding the availability of expert physicians and specialized equipment.

JGH Open 2022; 6:434-440.

Abstract
Background and Aim The American Society of Gastrointestinal Endoscopy (ASGE) and the European Society of Gastrointestinal Endoscopy (ESGE) have published guidelines for choledocholithiasis. However, the guidelines were formulated using data from a large number of patients with no to low risk of common bile duct (CBD) stones. This study aimed to assess the guidelines' predictive performance in a population with a high frequency of stones. Methods Data for three choledocholithiasis standard reference tests were retrospectively reviewed from January 2019 to June 2021. Clinical parameters were used to categorize patients into risk groups according to the guidelines, and then the guidelines' predictive abilities were calculated. Results Among 1185 patients, 521 were included. The stone prevalence was 61.0% (n = 318). Twelve (2.3%), 146 (28.0%), and 363 (69.7%) patients were classified into low‐, intermediate‐, and high‐risk groups according to the ASGE guidelines, and 30 (5.8%), 149 (28.6%), and 342 (65.6%) according to the ESGE guidelines. Focusing on the high‐risk group, the ASGE guidelines had a positive predictive value of 73.6 and a positive likelihood ratio of 1.78. The ESGE guidelines had a positive predictive value of 73.7 and positive likelihood ratio of 1.79. Both guidelines had equivalent areas under the receiver operating characteristic curve of 0.69 (95% confidence interval [CI]: 0.65–0.73) and 0.68 (95% CI: 0.64–0.72), respectively. Conclusion In the high‐risk group, the guidelines increased the chance of detecting choledocholithiasis by approximately 10% (61.0% prevalence to 73.6 and 73.7% positive predictive value). However, statistically, the guidelines had marginal discriminative performance in a population with high stone prevalence.

The Diagnostic Value of the CA19-9 and Bilirubin Ratio in Patients with Pancreatic Cancer, Distal Bile Duct Cancer and Benign Periampullary Diseases, a Novel Approach. Cancers (Basel) 2022; 14:cancers14020344. [PMID: 35053506 PMCID: PMC8774022 DOI: 10.3390/cancers14020344] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2021] [Revised: 01/06/2022] [Accepted: 01/07/2022] [Indexed: 12/13/2022] Open
Abstract
Distinction of pancreatic ductal adenocarcinoma (PDAC) in the head of the pancreas, distal cholangiocarcinoma (dCCA), and benign periampullary conditions, is complex as they often share similar clinical symptoms. However, these diseases require specific management strategies, urging improvement of non-invasive tools for accurate diagnosis. Recent evidence has shown that the ratio between CA19-9 and bilirubin levels supports diagnostic distinction of benign or malignant hepatopancreaticobiliary diseases. Here, we investigate the diagnostic value of this ratio in PDAC, dCCA and benign diseases of the periampullary region in a novel fashion. To address this aim, we enrolled 265 patients with hepatopancreaticobiliary diseases and constructed four logistic regression models on a subset of patients (n = 232) based on CA19-9, bilirubin and the ratio of both values: CA19-9/(bilirubin-1). Non-linearity was investigated using restricted cubic splines and a final model, the 'Model Ratio', based on these three variables was fitted using multivariable fractional polynomials. The performance of this model was consistently superior in terms of discrimination and calibration compared to models based on CA19-9 combined with bilirubin and CA19-9 or bilirubin alone. The 'Model Ratio' accurately distinguished between malignant and benign disease (AUC [95% CI], 0.91 [0.86-0.95]), PDAC and benign disease (AUC 0.91 [0.87-0.96]) and PDAC and dCCA (AUC 0.83 [0.74-0.92]) which was confirmed by internal validation using 1000 bootstrap replicates. These findings provide a foundation to improve minimally-invasive diagnostic procedures, ultimately ameliorating effective therapy for PDAC and dCCA.

Abstract
Determination of the cause of a biliary obstruction is often inconclusive from serum analysis alone without further clinical tests. To this end, serum markers as well as the composition of bile of 74 patients with biliary obstructions were determined to improve the diagnoses. The samples were collected from the patients during an endoscopic retrograde cholangiopancreatography (ERCP). The concentration of eight bile salts, specifically sodium cholate, sodium glycocholate, sodium taurocholate, sodium glycodeoxycholate, sodium chenodeoxycholate, sodium glycochenodeoxycholate, sodium taurodeoxycholate, and sodium taurochenodeoxycholate as well as bile cholesterol were determined by HPLC-MS. Serum alanine aminotransferase (ALT), aspartate transaminase (AST), and bilirubin were measured before the ERCP. The aim was to determine a diagnostic factor and gain insights into the influence of serum bilirubin as well as bile salts on diseases. Ratios of conjugated/unconjugated, primary/secondary, and taurine/glycine conjugated bile salts were determined to facilitate the comparison to literature data. Receiver operating characteristic (ROC) curves were determined, and the cut-off values were calculated by determining the point closest to (0,1). It was found that serum bilirubin was a good indicator of the type of biliary obstruction; it was able to differentiate between benign obstructions such as choledocholithiasis (at the concentration of >11 µmol/L) and malignant changes such as pancreatic neoplasms or cholangiocarcinoma (at the concentration of >59 µmol/L). In addition, it was shown that conjugated/unconjugated bile salts confirm the presence of an obstruction. With lower levels of conjugated/unconjugated bile salts the possibility for inflammation and, thus, neoplasms increase.

Abstract
Purpose The accurate differentiation between benign and malignant biliary stricture is significant but challenging. Tissue diagnosis of biliary stricture by endoscopy sampling can provide excellent specificity but insufficient sensitivity. For patients with suspected malignant biliary stricture (MBS) but non-malignant was reported in endoscopy tissue samples, we constructed a nomogram to predict malignancy and improve the overall diagnostic performance. Patients and Methods 232 patients with suspected MBS and underwent endoscopy tissue sampling from January 2017 to December 2019 were included, among which 123 patients’ endoscopy tissue samples were classified as non-malignant (including atypical, negative for malignancy, and nondiagnostic). Demographics, serum markers, radiological and sampling results of these 123 patients were collected to construct a nomogram using multivariate analysis. Results The nomogram was developed based on bilirubin, CA19-9, radiological result, and atypical sampling results and provided an AUC of 0.863 (95% CI 0.795–0.930) for predicting MBS. The specificity, sensitivity, and accuracy of endoscopy tissue diagnosis were 100.00%, 59.90%, and 68.53%, respectively. With the nomogram added, the overall diagnosis specificity, sensitivity, and accuracy were 95.24%, 89.20%, and 90.23%, respectively. Conclusion The nomogram can predict malignancy in patients whose endoscopy tissue diagnoses were non-malignant. The overall diagnostic performance was improved with the nomogram added.

Abstract
Biliary stenosis may represent a diagnostic and therapeutic challenge resulting in a delay in diagnosis and initiation of therapy due to the frequent difficulty in distinguishing a benign from a malignant stricture. In such cases, the diagnostic flowchart includes the sequential execution of imaging techniques, such as magnetic resonance, magnetic resonance cholangiopancreatography, and endoscopic ultrasound, while endoscopic retrograde cholangiopancreatography is performed to collect tissue for histopathological/cytological diagnosis or to treat the stenosis by insertion of stent. The execution of percutaneous transhepatic drainage with subsequent biopsy has been shown to increase the possibility of tissue diagnosis after failure of the above techniques. Although the diagnostic yield of histopathology and imaging has increased with improvements in endoscopic ultrasound and peroral cholangioscopy, differential diagnosis between malignant and benign stenosis may not be easy in some patients, and strictures are classified as indeterminate. In these cases, a multidisciplinary workup including biochemical marker assays and advanced technologies available may speed up a diagnosis of malignancy or avoid unnecessary surgery in the event of a benign stricture. Here, we review recent advancements in the diagnosis and management of biliary strictures and describe tips and tricks to increase diagnostic yields in clinical routine.

Abstract
Background To investigate characteristic clinical and imaging features and establish a scoring system for preoperative prediction of malignancy in the bulging duodenal papilla. Methods A total of 147 patients with bulging duodenal papilla (Benign enlargement n = 67; malignant enlargement n = 80) from our hospital between 2010 and 2020 were retrospectively analyzed. We investigated meaningful clinical and CT imaging features and established the score model through logistic regression and weighted. The calibration test, the ROC, AUC, and cut-off points were performed in score model. The model was also divided into three score ranges for convenient clinical evaluation. Results Three clinical and CT imaging features were finally included in the score model including direct bilirubin (DBil) increase >7 umol/L (3 points), pancreatic duct (PD) dilation >5 mm (2 points), and irregular shape (2 points). The AUCs of the primary predictive model and score model were 0.896 (95% CI, 0.835-0.940) and 0.896 (95% CI, 0.835-0.940), respectively. This scoring system presented with a sensitivity of 78.8% and a specificity of 88.1% when using 2.5 points as cutoff value. Three score ranges were also proposed for convenient clinical use as follows: 0-2 points; 3-4 points; 5-7 points. The number of patients with malignant duodenal papillary enlargement increased with the increasing scores. Conclusions We proposed a convenient scoring system to preoperative predict malignancy in the bulging duodenal papilla.

J Clin Med 2021; 10:jcm10051048.

Abstract
The diagnostic process for biliary strictures remains challenging in some cases. A broad differential diagnosis exists for indeterminate biliary strictures, including benign or malignant lesions. The diagnosis of indeterminate biliary strictures requires a combination of physical examination, laboratory testing, imaging modalities, and endoscopic procedures. Despite the progress of less invasive imaging modalities such as transabdominal ultrasonography, computed tomography, and magnetic resonance imaging, endoscopy plays an essential role in the accurate diagnosis, including the histological diagnosis. Imaging findings and brush cytology and/or forceps biopsy under fluoroscopic guidance with endoscopic retrograde cholangiopancreatography (ERCP) are widely used as the gold standard for the diagnosis of biliary strictures. However, ERCP cannot provide an intraluminal view of the biliary lesion, and its outcomes are not satisfactory. Recently, peroral cholangioscopy, confocal laser endomicroscopy, endoscopic ultrasound (EUS), and EUS-guided fine-needle aspiration have been reported as useful for indeterminate biliary strictures. Appropriate endoscopic modalities need to be selected according to the patient's condition, the lesion, and the expertise of the endoscopist. The aim of this review article is to discuss the diagnostic process for indeterminate biliary strictures using endoscopy.

Risk factors to differentiate between benign proximal biliary strictures and perihilar cholangiocarcinoma. HPB (Oxford) 2020; 22:1753-1758. [PMID: 32321675 DOI: 10.1016/j.hpb.2020.03.023] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2019] [Revised: 03/10/2020] [Accepted: 03/30/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND The aim of this study was to evaluate potential risk factors associated with benign lesions and perihilar cholangiocarcinoma (PHC) in patients presenting with proximal biliary strictures (PBS). METHODS Patients with PBS who were referred to a specialist HPB centre between 2008 and 2016 were identified. Patients with primary sclerosing cholangitis, metastatic PHC or hilar obstruction by a peripheral tumour were excluded. The final diagnosis was determined either by (1) resection histology or (2) combination of biopsy and clinical course. Multivariable analysis of clinical, laboratory and radiological data was undertaken to identify independent predictors of benign and malignant lesions. RESULTS 155 consecutive patients were identified, including 25 patients (16%) with benign PBS. Abdominal pain (odds ratio [OR] 3.36; p = 0.027), serum CA19.9 < 100 U/ml (OR 10.35; p = 0.001), and absence of mass on imaging (OR 4.66; p = 0.004) were all associated with the presence of benign lesions on multivariable analysis. CONCLUSIONS This study has identified several independent variables that may differentiate between benign and malignant proximal biliary strictures. A larger multi-institutional study would be warranted to validate these findings, and to develop a risk score to stratify patients with suspected PHC.

Abstract
The differential diagnosis for biliary strictures is broad. However, the likelihood of malignancy is high. Determining the etiology of a biliary stricture requires a comprehensive physical exam, laboratory evaluation, imaging, and ultimately tissue acquisition. Even then, definitive diagnosis is elusive, and many strictures remain indeterminant in origin. This literary review examines the diagnostic dilemma of biliary strictures and presents innovations in both histochemical and endoscopic techniques that have increased the diagnostic power of differentiating benign and malignant strictures. The field of tissue biopsy is revolutionizing with the advent of free DNA mutation profiling, fluorescence in situ hybridization (FISH), and methionyl t-RNA synthetase 1 (MARS 1), which allow for greater testing sensitivity. Endoscopic ultrasound, endoscopic retrograde cholangiopancreatography (ERCP), cholangioscopy, confocal laser endomicroscopy, and intraductal ultrasound build upon existing endoscopic technology to better characterize strictures that would otherwise be indeterminate in etiology. This review uses recent literature to insert innovative technology into the traditional framework of diagnostic methods for malignant biliary strictures.

Fernandez Y Viesca M, Arvanitakis M. Early Diagnosis And Management Of Malignant Distal Biliary Obstruction: A Review On Current Recommendations And Guidelines. Clin Exp Gastroenterol 2019; 12:415-432.

Abstract
Malignant biliary obstruction is a challenging condition, requiring a multimodal approach for both diagnosis and treatment. Pancreatic adenocarcinoma and cholangiocarcinoma are the leading causes of malignant distal biliary obstruction. Early diagnosis is difficult to establish as biliary obstruction can be the first presentation of the underlying disease, which can already be at an advanced stage. Consequently, the majority of patients (70%) with malignant distal biliary obstruction are unresectable at the time of diagnosis. The association of clinical findings, laboratory tests, imaging, and endoscopic modalities may help in identifying the underlying cause. Novel endoscopic techniques such as cholangioscopy, intraductal ultrasonography, or confocal laser endomicroscopy have been developed with promising results, but are not used in routine clinical practice. As the number of patients with malignant distal biliary obstruction who will undergo curative surgery is limited, endoscopy has a crucial role in palliation, to relieve biliary obstruction. According to the last European guidelines published in the management of biliary obstruction, self-expandable metal stents have a central place in biliary drainage compared to plastic stents. Endoscopic ultrasound has evolved impressively in the last decades. When standard techniques of biliary cannulation by endoscopic retrograde cholangiopancreatography fail, endoscopic ultrasound-guided biliary drainage is a good option compared to percutaneous drainage.

Abstract
Background: Obstructive jaundice is one of the most common symptoms which can be caused by both malignant and benign hepato-biliary-pancreatic diseases. The differences and the differential diagnostic roles of the serum CA19-9, total bilirubin (TBIL) and especially, the ratio of CA19-9 to TBIL in these patients have not been well elucidated. This study compared the differences and the differential diagnostic roles of the increase-folds of the serum CA19-9, TBIL and the ratio of increase-folds of CA19-9 to increase-folds of TBIL in 508 cases of malignant (MOJ) and benign (BOJ) obstructive jaundice patients. Methods: Totally, 508 cases of obstructive jaundice patients with pathological results were retrospectively enrolled. 342 cases were MOJ, including gallbladder adenocarcinoma, extrahepatic cholangiocarcinoma, periampullar adenocarcinoma and pancreatic adenocarcinoma.The other 166 cases were BOJ, including cholelithiasis, primary sclerosing cholangitis (PSC), IgG4 related sclerosing cholangitis (IRSD), inflammatory stricture of bile duct, and adenoma. The data of the increase-folds of serum CA19-9, TBIL and the ratio of increase-folds of CA19-9 to increase-folds of TBIL was collected and analyzed. The ROC (receiver operating characteristic) curve was adopted to determine the optimal cutoff value to evaluate their differential diagnostic roles. Results: The CA19-9 was elevated in 94.15% of the MOJ, compared to 67.10% in BOJ (P<0.0001). The increase-folds of the CA19-9 (76.52±15.04 vs 3.55±0.41, P< 0.0001) and the increase-folds of TBIL (7.10±0.25 vs 5.95±0.36, P=0.0034) and the ratio (14.96±5.05 vs 0.79±0.93, P=0.0026) in MOJ were significantly higher than BOJ. The ROC curves indicated that the TBIL showed minimal differential diagnostic power (AUC=0.590), the increase-folds of CA19-9 and the ratio showed stronger differential diagnostic power (AUC=0.815 and AUC=0.889, respectively). The optimal value of the increase-folds of serum CA19-9 and the ratio for differential diagnosis was 4.5 and 0.88, respectively. Further, the combination of the increase-folds of serum CA19-9 and the ratio could increase the specificity and accuracy of the diagnosis of MOJ. Conclusion: The serum CA19-9, TBIL and the ratio in MOJ and BOJ are significantly different. The ratio of the increase-folds of CA19-9 to increase-folds of TBIL has stronger differential diagnostic roles than the increase-folds of CA19-9 or TBIL alone. The combination of the increase-folds of the CA19-9 and the ratio can further improve the specificity and accuracy of the diagnosis of MOJ.

Abstract
OBJECTIVE To determine the diagnostic accuracy of Tokyo guidelines (TG) 2018/2013 (TG18/TG13) and predictors of poor prognosis in acute cholangitis. METHODS Retrospective 1-year study of consecutive hospital admissions for acute cholangitis. Prognosis was defined in terms of 30 d in-hospital mortality. RESULTS Of the 183 patients with acute cholangitis, diagnostic accuracy based on Charcot's triad, TG07 and TG18/TG13 was 67.8, 86.9 and 92.3% (p < .001), respectively. Regarding severity based on TG18/TG13, 30.6% of cases were severe. A poor prognosis was found in 10.9% of patients. After multivariate analysis, systolic blood pressure <90 mmHg (OR 11.010; p < .001), serum albumin <3 g/dL (OR 1.355; p = .006), active oncology disease (OR 3.818; p = .006) and malignant aetiology of obstructive jaundice (OR 2.224; p = .021) were independent predictors of poor prognosis. The discriminative ability of the model with these four variables was high (AUROC 0.842; p < .001), being superior to TG18/TG13 (AUROC 0.693; p = .005). CONCLUSIONS TG18/TG13 showed high diagnostic accuracy in acute cholangitis. Compared with TG18/TG13, the simplified severity model ≥2 allows easy selection of patients who will benefit from admission to the intensive care unit and early biliary decompression.

Abstract
Carlinoside is a unique compound well-known for its excellent curative potential in hepatitis. There is a substantial research gap regarding the medicinal use of carlinoside, as its concentrations are greatly variable (depending on locality). We cultivated Cajanus cajan using vermicompost as a major organic amendment at two locations (Sonitpur and Birbhum) with different soil types, but identical climate conditions. Sonitpur soils were richer in soil organic C (SOC), enzyme activation, and N/P content than Birbhum. However, vermi-treatment improved many soil properties (bulk density, water retention, pH, N/P/K, and enzyme activity) to narrow the locational gap in soil quality by 15-28%. We also recorded a many-fold increment in SOC storage capacities in both locations, which was significantly correlated with carlinoside, total phenol, and flavonoid contents in Cajanus leaves. This significantly up-regulated the carlinoside induced expression of the bilirubin-solubilizing UGT1A1enzyme in HepG2 cell and rat liver. Leaf extracts of vermicompost-aided plants could cure hepatitis in affected rat livers and in the HepG2 cell line. Accordingly, vermi-treatment is an effective route for the growth of Cajanus as a cash crop for biomedical applications and can produce a concurrent improvement in soil quality.

Abstract
Surface-immobilized pure DNA hydrogels were formed using a surficial primer-induced strategy and adopted as scaffold materials for biosensing applications.
Hydrogels are of great interest in the field of biosensing for their good biocompatibility, plasticity, and capability of providing 3D scaffolds. Nevertheless, the application of hydrogels has not been linked with broad surface biosensing systems yet. To overcome the limitations, here for the first time, surface-immobilized pure DNA hydrogels were synthesized using a surficial primer-induced strategy and adopted for biosensing applications. The DNA hydrogel 3D scaffold is successfully constructed on a transparent ITO electrode, which facilitates both colourimetric and electrochemical measurements. Results show that the hydrogel is able to wrap enzymes solidly and exhibits favourable stability under different conditions. Owing to the free diffusion of the micromolecular targets throughout the hydrogel, while isolating the enzymes from the macromolecular interferences outside the hydrogel, the direct colourimetric and electrochemical detection of hydrogen peroxide and bilirubin in serum is achieved. The detection limit of hydrogen peroxide in serum is 22 nM by colourimetric analysis and 13 nM by electrochemical measurement. The detection limit of bilirubin is 32 nM, a favourable limit that could be used in jaundice diagnosis. In addition, the enzyme@hydrogel can be easily regenerated and the catalytic activity is retained for a few cycles, thus allowing the recycling of the hydrogel-based biosensing system. The successful integration of DNA hydrogels with surface biosensing systems will greatly expand the applications of hydrogels for diagnostic and environmental monitoring purposes.

Abstract
Infection with the trematode Clonorchis sinensis is the most common human fluke infection in East Asian populations. Although this infection is associated with obstructive jaundice or choledocholithiasis, portal vein thrombosis has not been reported. Here, we report the first case of a 60-year-old man who had both C. sinensis infection and portal vein thrombosis with severe hyperbilirubinemia (75.4 mg/dl). He initially presented with abdominal pain and jaundice. Computed tomography revealed gallstones, common bile duct calculus, and thrombus in the left main branch of the portal vein. A nasobiliary tube was inserted under endoscopic retrograde cholangiography. Cytology of the bile juice revealed many C. sinensis eggs. The abdominal pain and jaundice improved following choledocholithotomy and combination treatment with a chemotherapeutic agent and anti-coagulant. This case suggests that inflammation around the portal vein as a result of C. sinensis infection has the potential to evoke portal vein thrombosis. Such cases should be treated with both a chemotherapeutic agent and anti-coagulant therapy. In conclusion, the possibility of infection with C. sinensis should be considered in patients presenting with hyperbilirubinemia and portal vein thrombosis, particularly in East Asian populations.

BACKGROUND To date, no studies have sought to determine the frequency of malignancy in patients presenting with a putative biliary stricture and normal liver function tests (LFTs). The primary aim of this retrospective cohort study was to determine the likelihood of malignancy in patients presenting with a biliary stricture and normal LFTs, a normal bilirubin level either alone or in combination with normal levels of liver enzymes [alkaline phosphatase (ALP) and alanine transaminase (ALT)]. A secondary aim was to determine any clinical/biochemical/sonographic features that may be associated with malignancy. METHODS Patients presenting over a 10-year period were included. Fifteen variables were analysed to determine their association with malignant disease. RESULTS Eight hundred and thirty patients with putative biliary strictures were included. Primary hepatopancreaticobiliary (HPB) cancers presented with a normal bilirubin and normal liver enzymes (ALP and ALT) in 6% of cases. Patients with a putative biliary stricture and a normal bilirubin level whose final diagnoses were pancreatic cancer, ampullary cancer, distal cholangiocarcinoma and hilar cholangiocarcinoma represented 21%, 13%, 7% and 9% of individuals diagnosed with these pathologies, respectively. Hypoalbuminaemia and isolated intrahepatic duct dilatation on ultrasound were significantly associated with malignancy in patients with normal bilirubin and completely normal LFTs. CONCLUSIONS This study has shown that patients with a putative biliary stricture and completely normal LFTs are unlikely to have a primary HPB malignancy. Those presenting with a normal bilirubin level, but deranged liver enzymes (ALP and/or ALT), are more likely to have malignant disease, and this should necessitate a higher degree of clinical suspicion.

Abstract
BACKGROUND Early differentiation of malignant from benign bile duct obstruction is of utmost importance. AIM To identify biochemical and clinical predictors for malignancy in patients with bile duct obstruction, and establish a predictive model by combining pre-treatment patient characteristics. A web-based application was developed for easy assessment of malignant bile duct probability (www.pmal-score.org). METHODS One thousand hundred and thirty-five patients [median age 66 (52-75) years, 53% male] with bile duct obstruction of various aetiologies were retrospectively evaluated at our tertiary referral centre. Multivariate logistic regression analysis identified factors as independently significant for malignant bile duct obstruction. A predictive risk score was established using ROC analysis and applied to an external validation cohort of 101 patients. RESULTS Three hundred and ninety-four patients had malignant bile duct obstruction proven by surgery, while in 741 patients benign obstruction was observed. Multivariate analysis identified various clinical factors to be predictive for malignancy. On the basis of eight predictors, a risk score for malignancy was developed [X = 0.025 * [age] + 1.239 * [1 if weight loss, otherwise 0] - 0.235 * [1 if pain, otherwise 0] + 0.649 * [1 if diabetes, otherwise 0] + 0.896 * [1 if jaundice, otherwise 0] + 0.109 * [bilirubin] + 0.0007 * [γ-GT] + 0.0003 * [AP] - 4.374]: A significant correlation between the predicted malignancy and the actual malignancy was found by ROC (AUC: 0.862; 95% CI 0.838-0.886, P < 0.0001). CONCLUSIONS This predictive risk score estimates the risk of malignancy in patients with bile duct obstruction, and it seems to be very accurate. A better prediction enables both earlier diagnosis of malignant obstructive disease and improved management of patients with bile duct obstruction, which may result in reduced morbidity and mortality.

Abstract
BACKGROUND Cholangiocarcinoma is a very aggressive tumor with poor survival. Therefore, early diagnosis and surgical resection are of paramount importance. Its diagnosis is difficult because access to the tumor is not easy. Biopsy is possible only for intrahepatic cholangiocarcinoma, which accounts for 10% of cases. Routine brush cytology from endoscopic retrograde cholangiopancreatography (ERCP) has a high specificity of 100% but unfortunately a low sensitivity of 30%. In this review we briefly describe new diagnostic techniques applicable to ERCP brush cytology specimens and targeting the genetic background of the disease, in particular fluorescence in situ hybridization (FISH) and digital image analysis (DIA). DATA SOURCES The PubMed database up to 2011 was used for the retrieval of relevant articles. The search terms FISH, fluorescence in situ hybridization, DIA, digital image analysis and cholangiocarcinoma were used. Both original and review articles were used. RESULTS FISH identifies cells with chromosomal abnormalities, mainly numerical aberrations, using a mixture of fluorescence-labeled probes. FISH offers a higher sensitivity than routine cytology, retaining a high level of specificity. The DIA criterion for malignancy is demonstration of aneuploidy. This technique increases the sensitivity to 40%, but the specificity remains low. Preliminary data from application to other tumors suggest that combination of FISH and DIA may be of further benefit. CONCLUSIONS The new techniques offer a significantly enhanced diagnostic efficacy in the evaluation of ERCP brush specimens. Apart from contributing to a more timely diagnosis, their wider application to cholangiocarcinoma may also facilitate the genetic study of the disease and add to our understanding of oncogenesis at the molecular level, with the prospect of identifying targets for novel therapeutic interventions.
