Successful robotic radical resection of hepatic echinococcosis located in posterosuperior liver segments

Figure 1 Contrast-enhanced magnetic resonance imaging and computed tomography manifestations of hepatic cystic and alveolar echinococcosis. A, D: Patient 1, cystic echinococcosis in caudate lobe; B, E: Patient 2, cystic echinococcosis in caudate lobe; C, F: Patient 3, cystic echinococcosis in segment VII; G: Patient 4, cystic echinococcosis in segment VIII; H, I: Patient 5, alveolar echinococcosis in segment VII/VIII. MR: Magnetic resonance; CT: Computed tomography.

Figure 2 Intraoperative visual field and status after removal of the specimen. A: Cystic echinococcosis was located in caudate lobe adjacent to the inferior vena and hepatic vein; B: Complete caudate resection; C: cystic echinococcosis was located in segment VII adjacent to the right hepatic vein; D: Segment VII resection. CE: Cystic echinococcosis; IVC: Inferior vena cava; RHV: Right hepatic vein; MHV: Middle hepatic vein.
