Multiple Biliary Hamartomas, The ‘‘Von Meyenburg Complexes’’
Multiple biliary hamartomas are rare benign malformations of the intrahepatic bile ducts first described by von Meyenburg in 1918. They originate from embryonic bile ducts that fail to involute. These are generally asymptomatic and usually encountered as

Development of extrahepatic bile ducts and mechanisms of tumorigenesis: Lessons from mouse models
Abstract The biliary system is a highly branched tubular network consisting of intrahepatic bile ducts (IHBDs) and extrahepatic bile ducts (EHBDs). IHBDs are derived from hepatic progenitor cells, while EHBDs originate directly from the endoderm through a separate branching morphogenetic process.

Aberrant Right Hepatic Duct Draining into the Cystic Duct: Clinical Outcomes and Management
Background. Aberrant right hepatic duct (ARHD) draining into cystic duct (CD) is relatively rare but clinically important because of its susceptibility to injuries during cholecystectomy.

Towards Simultaneous Segmentation of Liver Tumors and Intrahepatic Vessels via Cross-attention Mechanism [PDF]
Accurate visualization of liver tumors and their surrounding blood vessels is essential for noninvasive diagnosis and prognosis prediction of tumors. In medical image segmentation, there is still a lack of in-depth research on the simultaneous segmentation of liver tumors and peritumoral blood vessels. To this end, we collect the first liver tumor, and

Histological insight into the hepatic tissue of the Nile monitor (Varanus niloticus) [PDF]
The liver of reptiles is considered an important study model for the interaction between environment and hepatic tissue. Little is known about the histology of the liver of reptiles. The aim of the current study was to elucidate the histological architecture of the liver of the Nile monitor (Varanus niloticus).

On turbulent friction in straight ducts with complex cross section: the wall law and the hydraulic diameter [PDF]
We develop predictive formulas for friction resistance in ducts with complex cross-sectional shape based on the use of the log law and neglect of wall shear stress nonuniformities. The traditional hydraulic diameter naturally emerges from the analysis as the controlling length scale for common duct shapes as triangles and regular polygons. The analysis

Sclerosing Cholangitis in Behçet’s Disease
Introduction. Sclerosing cholangitis is characterized by an inflammatory and fibrotic lesion of intra- and/or extrahepatic bile ducts. When a causal mechanism of a bile duct lesion is identified, the sclerosing cholangitis is considered secondary.

Cirrose biliar secundária em doente com histiocitose X.
Histiocitose X or Histiocytosis of the Langerhans cells represents a complex spectrum of clinical alterations, resulting from infiltration by anomalous histiocytes of various organs, including the skin, bones, lungs, lymphatic ganglia and liver.
