BACKGROUND: /Aims. In cholangiocarcinoma, early metastatic spread via lymphatic vessels often precludes curative therapies. Cholangiocarcinoma invasiveness is fostered by an extensive stromal reaction, enriched in cancer-associated fibroblasts (CAF) and lymphatic endothelial cells (LEC). Cholangiocarcinoma cells recruit and activate CAF by secreting PDGF-D. Here we investigated the role of PDGF-D and liver myofibroblasts in promoting lymphangiogenesis in cholangiocarcinoma. METHODS: Human cholangiocarcinoma specimens were immunostained for podoplanin (LEC marker), α-SMA (CAF), VEGF-A, VEGF-C, and their cognate receptors (VEGFR2, VEGFR3)...

Choledochal cysts (CDCs) and biliary atresia (BA) are rare pediatric hepatobiliary anomalies that require surgical intervention due to increased risk of malignancy and liver failure, respectively. The underlying disease and operative procedures place patients at risk for long-term complications, which may continue to affect them into adulthood. Lack of a transitional care model in the health care system potentiates the challenges they will face following aging out of their pediatric providers' care. We sought to elucidate the long-term complications and challenges patients with CDCs and BA face, review the current literature regarding transitioning care, and propose guidelines aiding adult providers in continued care and surveillance of these patients...

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...

Cholangiocarcinoma (CCA) is an aggressive biliary tract malignancy with limited treatment options and low survival rates. The intrahepatic subtype comprises two forms: mucin-iCCA and mixed-iCCA. Epidermal growth factor-like domain multiple (EGFL7) is overexpressed in less differentiated liver tumors. The aim of this study was to assess the presence of EGFL7 due to its possible role in the growth of CCA. Hematoxylin and Eosin and periodic acid-Schiff staining were used to evaluate the morphological aspects and glycogen deposition...

Heterotopic tissue in the bile duct is a very rare condition. There are a few case reports of heterotopic tissue including gastric and pancreatic cells. However, we could not find any data regarding heterotopic chondroid tissue obstructing the common bile duct in the literature. A 56-year-old woman was admitted to our hospital with complaints of progressive jaundice and pruritus. Laboratory test results were within the normal limits except bilirubin and alkaline phosphatase which were 10.8 mg/dL and 256 IU/L, respectively...

Ampulla of Vater is a peculiar anatomical structure, characterized by the crossroad of three distinct epithelia: Intestinal, ductal pancreatic and biliary. Adenocarcinomas arising in this area represent an opportunity to understand the comparative biology of all periampullary malignancies. These neoplasms can exhibit intestinal, pancreaticobiliary or mixed features, whereas the subclassification based on morphology and immunohistochemical features failed in demonstrating a robust prognostic reliability. In the last few years, the molecular landscape of this tumor entity has been uncovered, identifying alterations that may serve as prognostic and predictive biomarkers...

Liver transplantation (LT) has the potential to cure patients with acute and chronic liver failure as well as a number of hepatic and biliary malignancies. Over time, due to the increasing demand for organs as well as improvements in the survival of LT recipients, patients awaiting LT have become sicker, and often undergo the procedure while critically ill. This trend has made the process of preoperative assessment and planning, intraoperative management, and postoperative management even more crucial to the success of LT programs...
