Oriental cholangiohepatitis is a condition occurring in the Asian population, characterised by recurrent bacterial cholangitis and presence of calculi within the intrahepatic bile ducts, biliary strictures and an increased risk for cholangiocarcinoma. It is an uncommon disease in the West that may not always be considered. The therapeutic approach is multidisciplinary and highly individual, and includes antibiotic therapy, endoscopic and percutaneous biliary drainage with stone removal and dilation of strictures, and in selected cases surgical resection of affected liver segments.

Recurrent pyogenic cholangitis (RPC) is an infective process involving the biliary tree typified by pigmented intraductal calculi with dilatation of the intra- and extrahepatic biliary tree. Previously endemic to South-east Asia, RPC can now be seen in Western countries with the increasing access to international travel and immigration. Affected patients are often plagued by recurrent bouts of cholangitis, and commonly suffer from complications such as abscess formation and biliary strictures. Read More

Background: Acute encephalopathy in a patient with alcoholic liver disease (ALD) is a commonly encountered emergency situation occurring most frequently due to liver failure precipitated by varying etiologies. Acute reversible cerebellar ataxia with confusion secondary to prolonged metronidazole use has been reported rarely as a cause of encephalopathy in patients with ALD.

Case Report: We describe a decompensated ALD patient with recurrent pyogenic cholangitis associated with hepatolithiasis who presented to the emergency department with sudden-onset cerebellar ataxia with dysarthria and mental confusion after prolonged use of metronidazole. Read More

A variety of diseases are included under the umbrella term 'cholangitis', including hepatobiliary diseases with an autoimmune pathogenesis (such as primary sclerosing cholangitis, primary biliary cholangitis, and IgG4-associated sclerosing cholangitis) and disease processes associated with intraductal stones and infectious etiologies (such as ascending bacterial cholangitis, recurrent pyogenic cholangitis, and liver fluke-associated cholangitis). Recent advances in the pathophysiologic bases of these disorders, particularly with respect to the autoimmune variety, are allowing improved diagnosis and prognostication as well as providing the opportunity to refine and re-imagine treatment modalities. The aim of this review is to highlight selected advances in cholangitis research that point to novel insights into the pathophysiology, diagnosis, and treatment of this diverse array of disorders.

Sclerosing cholangitis is a spectrum of chronic progressive cholestatic liver disease characterized by inflammation, fibrosis, and stricture of the bile ducts, which can be classified as primary and secondary sclerosing cholangitis. Primary sclerosing cholangitis is a chronic progressive liver disease of unknown cause. On the other hand, secondary sclerosing cholangitis has identifiable causes that include immunoglobulin G4-related sclerosing disease, recurrent pyogenic cholangitis, ischemic cholangitis, acquired immunodeficiency syndrome-related cholangitis, and eosinophilic cholangitis.

Recurrent Pyogenic Cholangitis (RPC) or Primary Hepatolithiasis is a common disease of the biliary tract in Asia, whereas it is usually not seen in Europeans. With increasing global mobility, the disease will be encountered in Europe more frequently, too. It should therefore be considered as a differential diagnosis in patients from endemic countries with recurrent symptoms of cholestasis/cholangitis and bile duct dilations, strictures and hepatolithiasis.

Recurrent pyogenic cholangitis (RPC) is a clinical syndrome characterized by repeated episodes of suppurative cholangitis due to hepatolithiasis and extrahepatic stones in the biliary ducts. It is now recognized as a distinct syndrome with a different natural history and pathoetiology than spontaneously occurring liver abscesses. Most commonly seen in East Asian populations, this syndrome is growing increasingly common in Western Nations due to migration patterns. Read More

The aim of this study was to review the clinical, radiographic, and pathologic features of cases of benign segmental cholangiectasia in non-Asian US patients with clinical concern for cholangiocarcinoma and compare these features with cases of recurrent pyogenic cholangitis (RPC) in Asian patients. A total of 10 non-Asian US patients with benign segmental cholangiectasia were included in this study. Nine of them underwent partial hepatic resection due to cholangiographic findings of segmental cholangiectasia with mural thickening and/or proximal biliary stricture. Read More

Ascariasis mainly contributes to the global helminthic burden by infesting a large number of children in the tropical countries. Hepato-biliary ascariasis (HBA) is becoming a common entity now than in the past owing to the frequent usage of ultrasonograms and endoscopic diagnostic procedures in the clinical practice. There are a variety of manifestations in HBA and diagnosis depends on a high index of suspicion in endemic areas coupled with subsequent confirmation by sonographic or endoscopic demonstration of the worm.

Recurrent pyogenic cholangitis (RPC) is characterized by repeated infections of the biliary system with the formation of stones and strictures. The management aims are to treat acute cholangitis, clear the biliary ductal debris and calculi, and eliminate predisposing factors of bile stasis. Operative options include hepatectomy and biliary drainage procedures or a combination of both; nonoperative options include endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic cholangiography (PTC) guided procedures.

Introduction: Biliobronchial fistula is rare. Very rarely it may be congenital, more frequently it is acquired as a complication of the hydatide cyst of the liver, pyogenic abscess, serious trauma and resection of the liver as well as recurrent cholangitis due to benign bile duct stricture or cholangiolithiasis. The main causes of the biliobronchial fistula are billiary obstruction and infectious lesion (abscess) in the liver. Read More

Recurrent pyogenic cholangitis (RPC), or oriental cholangiohepatitis, is characterized by intrabiliary pigment stone formation, whose main manifestation consists of recurrent episodes of cholangitis, although other biliopancreatic complications can also occur. RPC develops mainly in Asian patients, in whom this entity is one of the main causes of acute abdominal pain. The differential diagnosis should be established with all other entities associated with intrahepatic stone formation, which is more common in Asian countries compared with the predominance of gallstone formation in the West.

Primary hepatolithiasis (HL), recurrent pyogenic cholangitis, and oriental cholangiohepatitis are terms commonly used in Japan, Hong Kong, and Korea respectively, and describing the different aspects of the same disease, with "HL" indicating the pathologic changes, "recurrent pyogenic cholangitis" emphasizing the clinical presentation and suppurative inflammation, and "oriental cholangiohepatitis" highlighting its ethnic preference and mysterious nature. HL is predominantly a disease of the far east and shows great regional differences in the incidence and the type of intrahepatic stones. Pathologically, it is characterized by pigmented calcium bilirubinate stones within dilated intrahepatic bile ducts featuring chronic inflammation, mural fibrosis, and proliferation of peribiliary glands, without extrahepatic biliary obstruction.

Oriental cholangiohepatitis (OCH) also called recurrent pyogenic cholangitis is characterized by intrahepatic duct calculi, strictures, and recurrent infections. In turn cholangitis can result in multiple hepatic abscesses, further biliary strictures, and in severe cases, progressive hepatic parenchymal destruction, cirrhosis, and portal hypertension. Magnetic resonance cholangiopancreatography (MRCP) and conventional T1-weighted (T1W) and T2-weighted (T2W) magnetic resonance imaging (MRI) findings have been described in patients with OCH.

The so-called bile duct adenoma and peribiliary glands are characterized by the expression of two foregut antigens (designated D10 and 1F6) and secretion of acid mucin. On account of this similarity in phenotype and their frequent close association with a large caliber bile duct, it was earlier suggested that bile duct adenoma represent a peribiliary gland hamartoma. Here, we compare the expression of 13 tissue antigens in bile duct adenomas, other benign bile duct lesions, and various foregut-derived tissues, to further investigate the bile duct adenoma phenotype and pathogenesis.
