BACKGROUND Biloma is the collection of bile outside the biliary tree as a result of visceral perforation. The most common site of disruption is the gallbladder, whereas common bile duct lesions usually occur following medical procedures or trauma. Spontaneous perforation of the common bile duct has been previously reported in the literature. Retroperitoneal biloma secondary to spontaneous perforation of the common bile duct is an extremely rare pathological entity. The purpose of this report is to inform clinical doctors of this rare entity, which can have fatal consequences for the patient. CASE REPORT We present the case of an 89-year-old man who was hospitalized with symptoms of vomiting, nausea, fatigue, and diffuse abdominal pain. The clinical examination and blood tests revealed peritonitis, a finding which was confirmed by the computed tomography of the abdomen as a retroperitoneal fluid collection, extending from the region posterior to the duodenum and head of the pancreas to the right inguinal fossa. As the patient's clinical status deteriorated, an urgent laparotomy was performed, revealing the presence of retroperitoneal biloma secondary to spontaneous perforation of the common bile duct. The operation was never completed as the patient died during the operation. CONCLUSIONS The diagnosis of this entity is difficult and is made during surgery. A large spectrum of treatment approaches has been used, but, regardless of the method, the goal is to halt the spreading abdominal contamination with bile and to treat the associated biliary pathology.

Aims: Obeticholic acid (OCA) was approved for the treatment of primary biliary cholangitis (PBC) patients, as it can significantly improve the level of serum alkaline phosphatase. However, OCA-induced liver injury in PBC patients puts them at risk of acute chronic liver failure, thus limiting the clinical application of OCA. Osteopontin (OPN), an extracellular cell matrix molecule, is highly induced in many cholestatic liver diseases. Read More

Electronic address:

Intrahepatic cholangiocarcinoma (iCCA), the second most common primary liver cancer, is a highly lethal epithelial cell malignancy exhibiting features of cholangiocyte differentiation. iCCAs can potentially develop from multiple cell types of origin within liver, including immature or mature cholangiocytes, hepatic stem cells/progenitor cells, and from transdifferentiation of hepatocytes. Understanding the molecular mechanisms and genetic drivers that diversely drive specific cell lineage pathways leading to iCCA has important biological and clinical implications. Read More

The aims of this retrospective study were to characterize the epidemiological, clinical, histopathological, and microbiological findings as well as surgical outcomes in dogs admitted to a specialist veterinary hospital in Hong Kong for surgical management of gallbladder mucocoele (GBM). Inclusion criteria were cases with histopathological diagnosis of GBM and accompanying abdominal imaging, serum biochemistry, bile culture, and liver biopsy histology results. Fifty-six cases met the inclusion criteria. Read More

Abstract: Neuroendocrine tumors (NETs) are heterogeneous group of tumors arising from enterochromaffin cells. Neuroendocrine tumors are most commonly found in bowel and pancreatic tissue. Because of paucity of enterochromaffin cells in biliary tract, NETs of bile duct are very rare. Read More

We investigated the expression of insulin-like growth factor 1 (IGF-1) and IGF-1 type 1 receptor (IGF-1R) in skeletal muscle fiber types in chickens with hepatic fibrosis induced by bile duct ligation (BDL). Eleven hens, approximately 104 weeks old, were randomly assigned to BDL (n = 4) and sham surgery (SHAM; n = 7) groups. In BDL hens, histopathology revealed marked bile duct proliferation and liver fibrosis. Read More
