The study, entitled "RCT study of laparoscopic middle hepatic venous guidance versus conventional ananatomical hemihepatectomy", was designed to compare the efficacy of two different ananatomical hemihepatectomy procedures under laparoscopy.

In theory, the advantages of anatomical hemihepatectomy guided by middle hepatic vein are as follows: 1) correctly guiding the transecting plane of the liver parenchyma can reduce the cross-sectional area of the liver and avoid damaging the vascular ducts of the pre-cut liver. so as to reduce the residue of necrotic tissue without blood supply and reduce the occurrence of postoperative complications. 2) active anatomy and exposure of hepatic vein can avoid uncontrollable bleeding after passive injury of hepatic vein, and laparoscopic anatomy has obvious advantage in exposing hepatic vein. 3) it may reduce the early recurrence rate of hepatocellular carcinoma after operation.
According to textbooks and the views of some scholars at present, traditional anatomical hepatectomy (non-hepatic vein-guided anatomical hepatectomy) has the following advantages: 1) avoiding exposure of hepatic vein can reduce the probability of injury to the trunk of hepatic vein, thus reduce the risk of massive bleeding during operation; 2) the difficulty of operation is relatively low, and a better short-term and long-term effect can be obtained.
95 patients with primary HCC were divided into the middle hepatic vein guidance group(n=45) and the traditional group(n=45) according to the odd and even Numbers, and sealed into envelopes.Outcomes were monitored and evaluated during the 3-year follow-up period
