Abstract: Objective To introduce how to identify intrahepatic anatomical structure by laparoscopic ultrasound （LUS）. Methods In one case of laparoscopic hepatectomy, using LUS to complete liver map scanning through different Trocars was performed and its imaging was collected. Results Several standard imaging of intrahepatic anatomical structure were obtained by axial rotation scanning of LUS： ①Right hepatic pedicle, right hepatic vein and middle hepatic vein were scanned by LUS through a subxiphoid Trocar. The right hepatic pedicle branched out into AT and PP, and then branched out into P5, P8 and P6, P7; V5d, V6, V8d and AFV flowed into the right hepatic vein successively, while V4, V5v and V8v flowed into the middle hepatic vein. ②Left hepatic pedicle, left hepatic vein, and middle hepatic vein were scanned by LUS through a trocar under the right costal margin. The left hepatic pedicle branched out into P2, P3, P4, V2, V3 flowed into left hepatic vein, and inferior vena cava and the vertical axis of middle hepatic vein were also scanned from this way. Conclusion The “standard imaging” of LUS in liver scaning is very helpful to identify the intrahepatic anatomical structure correctly. Surgeons must master the essential technique of LUS in liver scaning, which needs in-depth study and repetition training. After that, LUS would play a guiding role in laparoscopic hepatectomy.
