Background: Recent research indicates a role of gut microbiota in development and progression of life-threatening diseases such as cancer. Carcinomas of the biliary ducts, the so-called cholangiocarcinomas, are known for their aggressive tumor biology, implying poor prognosis of affected patients. An impact of the gut microbiota on cholangiocarcinoma development and progression is plausible due to the enterohepatic circulation and is therefore the subject of scientific debate, however evidence is still lacking.

Anatomical structures of the liver could be reconstructed three dimensionally from preoperative cross-sectional imaging for over 20 years. This three-dimensional (3D) representation not only optimizes the preoperative planning options but also the communication of specific operation-relevant structures can be improved using 3D models. In addition to a plastic and interactive visualization of 3D organ models, the disruptive technology of virtual reality (VR) can also provide a possibility for structured training and further education regarding surgical anatomy of the liver and operation planning.

Article Synopsis
  • Perihilar cholangiocarcinoma is a rare bile duct cancer, and while surgery is the main treatment option, the survival rates after surgery remain low due to influences like tumor size and invasion levels.
  • The study analyzed data from 214 patients over 11 years to assess how perineural, lymphangio, and vascular invasion affect overall survival following surgical resection.
  • Results indicated that while perineural invasion is common, it has a less significant impact on survival compared to lymphangio and vascular invasions, particularly in advanced cases (Bismuth type IV), which showed stronger associations with poor outcomes.

Article Synopsis
  • The Barcelona Clinic Liver Cancer (BCLC) staging system is crucial for treating hepatocellular carcinoma (HCC); recent updates allow for BCLC stage B patients to consider liver transplantation, while hepatectomy is now discouraged.
  • A systematic review analyzed 31 studies involving 3163 patients to compare survival rates, postoperative complications, and patient selection for liver resection versus transplantation in BCLC stage B patients.
  • Results showed that while resection had a 50-month survival and a 15-month recurrence-free period, data on transplantation was limited, with only one study reporting on it, indicating the need for more research in this area.

Minimally invasive esophagectomies, including robot-assisted procedures, have demonstrated superiority over traditional open surgery. Despite the prevalence of transhiatal and transthoracic approaches, cervical access is less common in minimally invasive esophageal surgery. Advancements in robotic systems, such as the da Vinci Single Port (SP), enable controlled transcervical extrapleural mediastinoscopic access, potentially reducing pulmonary complications and extending surgical options to patients with comorbidities.

Background: Cholangiocarcinoma (CCA) is a fatal cancer of the bile duct with a poor prognosis owing to limited therapeutic options. The incidence of intrahepatic CCA (iCCA) is increasing worldwide, and its molecular basis is emerging. Environmental factors may contribute to regional differences in the mutation spectrum of European patients with iCCA, which are underrepresented in systematic genomic and transcriptomic studies of the disease.

Distinguishing primary liver cancer (PLC), namely hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA), from liver metastases is of crucial clinical importance. Histopathology remains the gold standard, but differential diagnosis may be challenging. While absent in most epithelial, the expression of the adherens junction glycoprotein N-cadherin is commonly restricted to neural and mesenchymal cells, or carcinoma cells that undergo the phenomenon of epithelial-to-mesenchymal transition (EMT).
