Robotic liver surgery has gained more acceptance as a feasible, safe, and effective procedure for the treatment of both benign and malignant indications. However, robotic left hepatectomy is still technically demanding. We describe our surgical technique of a robotic left hepatectomy using indocyanine green fluorescence imaging for a large biliary cyst.

Three-dimensional (3D) cellular systems are relevant models for investigating organogenesis. A hydrogel-based method for biliary cysts production and their characterization is proposed. This protocol unravels the barriers of 3D characterization, with a straightforward and reliable method to assess cyst formation efficiency, sizes, and to test their functionality.

To help assess the molecular mechanisms underlying zebrafish biliary-driven liver regeneration, we established a liver injury model in which the nitroreductase-expressing hepatocytes are genetically ablated upon metronidazole treatment. In this protocol, we describe how to adeptly manipulate, monitor and analyze hepatocyte ablation and biliary-driven liver regeneration.

FAQs
Two developmental pathways are highlighted: a congenital abnormality in bile-duct development or a localized dilation of an existing intrahepatic duct. Either pathway can create a space in which bile or clear fluid accumulates. Distinguishing these possibilities helps clinicians interpret the lesion in relation to the biliary system rather than treating it as an unrelated simple hepatic cyst.
Communication with the biliary tree is a key diagnostic feature because it links the cystic lesion to the intrahepatic ducts. Imaging that demonstrates this relationship can separate an intrahepatic biliary cyst from other hepatic cysts and biliary disorders. The distinction matters because the lesion's ductal association influences diagnostic interpretation and may affect subsequent management decisions.
Symptoms are not the only determinants of clinical significance. Infection, obstruction, interval growth, and possible malignant potential are additional considerations when evaluating an intrahepatic biliary cyst. These factors help explain why two lesions with similar cystic appearances may receive different levels of attention or intervention. Assessment therefore combines imaging findings with the patient's clinical course.
Ultrasound, computed tomography, and magnetic resonance cholangiopancreatography contribute complementary views of the lesion. Together, they can characterize its location, internal features, and relationship with the biliary tree. Using these studies to gather complementary information improves the effort to distinguish an intrahepatic biliary cyst from other hepatic cysts and supports a more tailored clinical assessment.
Imaging assessment should establish three linked features: the lesion's location within the liver, its internal characteristics, and whether it communicates with the biliary tree. Ultrasound, computed tomography, and magnetic resonance cholangiopancreatography are the named tools for this characterization. The resulting pattern supports differential diagnosis, particularly separation from other hepatic cysts and biliary disorders.
Management is selected according to symptoms, infection, obstruction, growth, and malignant potential. Observation may be appropriate in selected situations, whereas drainage or surgery may be considered when clinical or lesion-related concerns justify intervention. This conditional approach prevents imaging appearance alone from determining care and links treatment choice to the lesion's behavior and clinical impact.
Accurate distinction places the lesion in the correct biliary context and helps avoid treating all hepatic cysts as equivalent findings. Imaging contributes by showing location, internal features, and possible communication with the ducts. That information supports decisions about observation, drainage, or surgery when symptoms, infection, obstruction, growth, or malignant potential make management necessary.
