手术主要分为三大部分，分别是腹腔镜下肝十二指肠韧带淋巴结清扫术，腹腔镜下右半肝切除术，腹腔镜下胆肠吻合术。患者麻醉后取仰卧位，"提拉法"建立气腹，五孔法置入Trocar及操作器械。首先，解剖并骨骼化清扫肝十二指肠韧带，显露各血管及胆管分支，于十二指肠上缘切断胆总管，同时切除胆囊。其次，充分游离右半肝，解剖游离左肝管后在距肿瘤上方1 cm处并将其切断，离断门静脉右支，沿半肝缺血线切除右半肝及尾状叶右侧部。最后，将空肠切断后上提与左肝管行胆肠吻合及空肠间侧侧吻合，延长切口，取物袋取出标本。

The operation is mainly divided into three parts: Laparoscopic hepatoduodenal ligament lymph node dissection, laparoscopic right hemihepatectomy and laparoscopic cholangiojejunostomy. After anesthesia, the patient took the supine position, "lifting method" to establish pneumoperitoneum, and trocar and operating instruments were placed using five hole method. Firstly, dissect and skeletonize the hepatoduodenal ligament, expose the internal blood vessels and bile duct branches, cut off the common bile duct at the upper edge of the duodenum, and remove the gallbladder at the same time. Then, the right half of the liver was fully dissociated. After dissecting the free left hepatic duct, it was cut off at 1cm above the tumor, the right branch of the portal vein was cut off, and the right half of the liver and the right part of the caudate lobe were removed along the hemihepatic ischemia line. Finally, the jejunum was lifted up to the left hepatic duct, after biliary-enteric anastomosis and intestinal anastomosis, the incision was prolonged, and the specimen was taken out of the bag.
