Laparoscopic hepatectomy based on diseased bile duct tree territory guided by double landmarks for hepatolithiasis: A case report

Figure 1 Schematic diagram of enhanced magnetic resonance imaging, and 3D reconstruction results before surgery. A-C: Coronal and axial magnetic resonance imaging views showing the distribution of the lesion; D: Axial magnetic resonance image revealing dilated bile ducts; E: Magnetic resonance cholangiopancreatography clearly delineates the affected bile ducts and pancreatic ducts; F: 3D reconstruction model demonstrating the spatial relationships of intrahepatic vasculature from multiple perspectives, with volumetric analysis of the future liver remnant.
