Choledochoscopy it's a common method of intraoperative exploring of the extrahepatic biliary ducts and partially of the intrahepatic ones. He is used both in the open and laparoscopic surgery. We consider the operative cholangiogram, preferably transcystic, as a first step who precedes the endoscopic exploration. The transcystic choledochoscopy has specific and relatively narrow indications: undulated biliary ducts, 1-3 gallstones. The transcholedocian choledochoscopy permit a direct and complete exploration of the biliary ducts. The important diagnostic help that fibrocholedochoscopy gives in, it's accomplished by the possibility of therapeutic maneuvers (especially the gallstones extraction), which offers the quality of a miniinvasive, elegant and harmless treatment technique.

Cholestasis is a multifactorial hepatobiliary disorder, characterized by obstruction of bile flow and accumulation of bile, which in turn causes damage to liver cells and other tissues. In severe cases, it can result in the development of life-threatening conditions, including cirrhosis and liver cancer. Paeoniflorin (PF) has been demonstrated to possess favourable therapeutic potential for the treatment of cholestasis.

Purpose: Intrahepatic cholangiocarcinoma (ICC) arises from the epithelial cells of the bile ducts present inside the liver parenchyma and is associated with an overall poor prognosis due to advanced disease stage at the time of diagnosis. We used the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database to determine ICC-related mortality patterns in the United States from 1999 till 2020.
Methods: Age-adjusted mortality rates (AAMR) and crude mortality rates (CMR) were extracted from the CDC WONDER database.

Cell models emulating an in vitro parasitic infection can greatly improve our understanding of helminthiases. Nonetheless, it remains challenging to select an appropriate in vitro model to study molecular pathogenesis of infections by trematodes having a complex life cycle. Therefore, adequate models are in high demand.

Cholangitis, defined as the inflammation of the bile ducts, is the most frequent complication after Kasai hepatoportoenterostomy in patients with biliary atresia (BA). This review seeks to provide a comprehensive synthesis of current knowledge on diagnosing and managing BA-associated cholangitis while identifying gaps in the existing literature. A scoping literature review was conducted to gather global insights into the definition, evaluation, and management of post-Kasai cholangitis, illustrated through data from the Swiss Biliary Atresia Registry (SBAR).

Biliary atresia (BA) is a severe neonatal cholestatic disorder marked by fibro-obliteration of the extrahepatic and intrahepatic bile ducts. It is the most common cause of pediatric end-stage liver disease and the leading indication for liver transplantation in children. There is significant heterogeneity in the etiology, involving various genetic and environmental factors such as viral infection, immune dysregulation and genetic predisposition to defective hepatobiliary development.
