该视频是1例明显肝硬化背景的原发性肝癌，肿瘤紧邻肝中静脉、肝右静脉、右前肝蒂，肿瘤具有包膜，未见脉管癌栓。充分术前评估后，予以施行机器人肝右前叶（S5/8）段切除。术中采用经前裂、经laennec膜入路，沿laennec膜显露右前肝蒂、肝中静脉、肝右静脉，完整切除肝右前叶。该患者肝硬化明显，肿瘤位置特殊，操作复杂。手术解剖层面清晰、管道结构完整显露，残肝流入流出道保护完好，体现了达芬奇手术机器人系统在复杂肝切除手术中明显的技术优势。

This video shows a case of primary liver cancer with obvious liver cirrhosis background. The tumor is close to the middle hepatic vein，right hepatic vein，and right anterior hepatic pedicle. After adequate preoperative evaluation，robotic right anterior lobe（S5/8）segmentectomy was performed. During the operation，the robot’s high-definition magnified field of view and the advantages of the instruments were fully utilized，and the right anterior hepatic pedicle，middle liver，and right hepatic vein were exposed through the trans-laennec membrane approach，and the right anterior lobe of the liver was completely resected. It reflects the obvious technical advantages of the da Vinci surgical robot system in complex liver resection.
