Cholangiolocellular carcinoma (CLC) is a unique subtype of primary liver carcinoma, which sometimes coexists with hepatocellular carcinoma (HCC), cholangiocarcinoma and combined hepatocellular-cholangiocarcinoma (cHCC-CCA). "Ductal plate malformation" (DPM)-pattern of primary liver carcinoma, which resembles biliary lesions in Caroli disease and von Meyenburg complex, is sometimes associated with CLC. We examined genetic alterations of hTERT promoter (hTERT), IDH1 or 2 (IDH1/2), KRAS, ARID1A, PBRM1, ARID2, BAP1, p53 and their association with histologic features such as proportion of CLC and DPM-pattern in 77 patients with primary liver carcinoma diagnosed as cHCC-CCA or CLC.

Purpose: Cholangiocarcinomas (CC), tumors derived from epithelial biliary cells, define a heterogeneous entity based upon their anatomic localization (intra- versus extrahepatic) and, for those developing in the liver, depending on the aspect of non-tumor liver (normal versus cirrhosis). The aim of the study was to characterize the molecular heterogeneity of the different types of CC by a global proteomic approach.
Experimental Design: Thirty-three tumor samples from 17 intrahepatic CC (iCC) including 9 and 8 developed on normal (iCC ) and cirrhotic liver (iCC ), respectively; 5 hilar CC (CC ), 5 CC developed in the pancreatic portion of the bile duct (CC ) and 6 hepatocellular carcinoma (HCC), were submitted to label-free quantitative proteomic analysis.

The cholangipathies are a class of liver diseases that specifically affects the biliary tree. These pathologies may have different etiologies (genetic, autoimmune, viral, or toxic) but all of them are characterized by a stark inflammatory infiltrate, increasing overtime, accompanied by an excess of periportal fibrosis. The cellular types that mount the regenerative/reparative hepatic response to the damage belong to different lineages, including cholagiocytes, mesenchymal and inflammatory cells, which dynamically interact with each other, exchanging different signals acting in autocrine and paracrine fashion.

Primary Biliary Cholangitis (PBC) is a chronic autoimmune liver disease characterised by progressive destruction of intrahepatic bile ducts. The strongest genetic association is with HLA-DQA1*04:01, but at least three additional independent HLA haplotypes contribute to susceptibility. We used dense single nucleotide polymorphism (SNP) data in 2861 PBC cases and 8514 controls to impute classical HLA alleles and amino acid polymorphisms using state of the art methodologies.

Peribiliary glands (PBG) are a source of stem/progenitor cells organized in a cellular network encircling large bile ducts. Severe cholangiopathy with loss of luminal biliary epithelium has been proposed to activate PBG, resulting in cell proliferation and differentiation to restore biliary epithelial integrity. However, formal evidence for this concept in human livers is lacking. Read More

Acute abdomen in patients with malignant tumors is called malignant acute abdomen, often seen in the digestive system tumor or abdominal pelvic metastasis of the other primary tumors. Bleeding, perforation, gastrointestinal obstruction, biliary obstruction with infection, acute peritonitis are acute and severe, however, prevention is more important than treatment. For high-risk patients, even if acute abdomen does not occur when the disease is diagnosed, we should make precautions, including actively local treatment of local lymph nodes or primary lesions and careful choice of drugs.

Background: Laparoscopic common bile duct exploration (LCBDE) is gaining popularity over endoscopic retrograde cholangiopancreatography (ERCP) for the management of common bile duct stones. However, its application has been almost exclusively following preoperative stone confirmation via magnetic retrograde cholangiopancreatography (MRCP), endoscopic ultrasound (EUS) or ERCP.
