手术采取左侧60°卧位，术中打开下腔静脉旁间隙及下腔静脉前间隙，在第一肝门预置阻断带，阻断第一肝门，打开尾状叶尾状突，沿Rouviere沟寻找右后叶肝Glisson鞘，予以悬吊并结扎，松开第一肝门阻断，术中超声确定肿瘤、右肝静脉位置及右后叶血管是否阻断完全。沿缺血线打开肝脏被膜，利用超声刀扫地法打开肝实质，翻书式逐层分离，切割闭合器离断右后区Glisson鞘，在右后区Glisson鞘上方找到肝右静脉，沿肝静脉左侧向第二肝门方向分离，从下往上，逐条离断肝短静脉及腔静脉韧带，上下合围显露右肝静脉根部并利用切割闭合器离断，最后分离肝周韧带，完整切除右后叶并装入标本袋，于下腹取横切口取出标本。

The operation was performed by using left 60°lying position. During the operation, the paravena cava and the anterior space of inferior vena cava were dissected. The first hepatic portal was blocked by using a pre-set blocking band, then the caudate lobe was exposed. The Glisson sheath of the right posterior lobe liver was identified along the Rouviere ditch, therefore suspension and ligation were carried out, then first hepatic portal was released. During the operation, ultrasound was used to locate the tumor and right hepatic vein and to determine whether vessels of right posterior lobe were blocked completely. To dissect the hepatic capsule along the ischemic line, to expose the liver parenchymalayer by layer by using ultrasonic knife. To disconnect the Glisson sheath of right posterior lobe by using closure device, and to locate the right hepatic vein above Glisson sheath of right posterior region. To dissect the left side of the hepatic vein to the second hepatic portal, from bottom to top, to cut off the short hepatic vein and the ligament of the vena cava one by one, to expose the root of the right hepatic vein and to cut off right posterior lobe by using closure devices, which was put into a specimen bag. The specimen was taken out through the transverse incision in the lower abdomen.
