Common bile duct (CBD) stone is a relatively frequent disorder with a prevalence of 10-20% in patients with gallstones. This is also associated with serious complications, including obstructive jaundice, acute suppurative cholangitis, and acute pancreatitis. Early diagnosis and prompt treatment is the most important for managing CBD stones. According to a recent meta-analysis, endoscopic ultrasonography and magnetic resonance cholangiopancreatography have high sensitivity, specificity, and accuracy for the diagnosis of CBD stones...

REVIEW
Sang Woo Cha
Intrahepatic duct (IHD) stone is the presence of calculi within the intrahepatic bile duct specifically located proximal to the confluence of the left and right hepatic ducts. This stone is characterized by its intractable nature and frequent recurrence, requiring multiple therapeutic interventions. Without proper treatment, biliary strictures and retained stones can lead to repeated episodes of cholangitis, liver abscesses, secondary biliary cirrhosis, portal hypertension, and death from sepsis or hepatic failure...

Transforming growth factor-β (TGF-β) plays a central role in hepatic fibrogenesis. This study investigated the function and mechanism of bone morphogenetic protein-2 (BMP-2) in regulation of hepatic fibrogenesis. BMP-2 expression in fibrotic liver was measured in human tissue microarray and mouse models of liver fibrosis induced by bile duct ligation surgery or carbon tetrachloride administration. Adenovirus-mediated BMP-2 gene delivery was used to test the prophylactic effect on liver fibrosis. Primary hepatic stellate cells (HSC), HSC-T6 and clone-9 cell lines were used to study the interplay between BMP-2 and TGF-β1...

An 89-year-old man was referred to our hospital for treatment of hepatolithiasis causing recurrent cholangitis. He had undergone a prior Whipple procedure. Computed tomography demonstrated left-sided hepatolithiasis. First, we conducted peroral direct cholangioscopy (PDCS) using an ultraslim endoscope. Although PDCS was successfully conducted, it was unsuccessful in removing all the stones. The stones located in the B2 segment were difficult to remove because the endoscope could not be inserted deeply into this segment due to the small size of the intrahepatic bile duct...

Biodegradable self-expanding stents are an emerging alternative to standard biliary stents as the development of endoscopic insertion devices advances. The aim was to systematically review the existing literature on biodegradable biliary stents. In-vivo studies on the use of biodegradable stents in the biliary duct were systematically reviewed from 1990 to 2017. Despite extensive research on the biocompatibility of stents, the experience so far on their clinical use is limited. A few favorable reports have recently been presented on endoscopically and percutaneously inserted self-expanding biodegradable polydioxanone stents in benign biliary strictures...

Primary sclerosing cholangitis (PSC) is a chronic inflammatory disease of the hepatobiliary system characterized by chronic inflammation, progressive fibrosis, stricture formation and destruction of extrahepatic and intrahepatic bile ducts. Areas covered: The increased incidence of cholangiocarcinoma (CCA) in PSC has been well documented and can be explained by the continuous inflammation in the biliary tree leading to an enhanced dysplasia-carcinoma sequence. Although PSC patients may progress to liver cirrhosis; CCA most commonly occurs between the ages of 30 and 45 years when cirrhosis has not yet developed...

BACKGROUND: Liver cirrhosis is associated with increased intrahepatic resistance due to hepatic fibrosis and exaggerated vasoconstriction. Recent studies have indicated that proton pump inhibitors (PPIs), in addition to acid suppression, modulate vasoactive substances and vasoresponsiveness. PPIs are frequently prescribed in patients with cirrhosis due to a higher prevalence of peptic ulcers, however other impacts are unknown. METHODS: Liver cirrhosis was induced in Sprague-Dawley rats with common bile duct ligation (BDL)...

Intrahepatic cholangiocarcinoma(ICC) is generally found late along with extremely poor prognosis and lack of effective and standardized treatment. Tremendous heterogeneities exist in onset factors, geographic distribution, clinical manifestation, and biological characteristics of ICC patients. However, the relevant causes and mechanisms have not been clearly illustrated. Recent studies indicate that the diverse celluar origins of ICC, including liver cells, bile duct epithelial cells, glandular cells around the duct, and liver stem cells, etc...
