To investigate the feasibility and safety of establishing a liver suspension system by using the right inferior vena cava approach in laparoscopic right hepatectomy for HCC.

From March 2017 to March 2019, 120 patients with liver cancer underwent laparoscopic right hepatectomy (LRH) were enrolled into present prospective randomized controlled study. Patients were randomly divided into traditional group (n=60), and suspension group (n=60), while patients in traditional group received traditional LRH, and patients in suspension group received LRH with the establishment of a liver suspension system by using the right inferior vena cava approach. SPSS18.0 software was used for statistical analysis. The measurement data, such as relevant indicators in perioperative period, were expressed as(±s) and were analyzed by using independent sample t test. Count data such as postoperative complications and postoperative recurrence rate were expressed as % and were analyzed by using χ² test. A P value of <0.05 was considered as statistically significant difference.

There was no perioperative death in both two groups. The operation time, hepatic portal Pringle blocking time, intraoperative blood loss and blood transfusion cases in suspension group were significantly less than those in traditional group respectively (P<0.05). There was no significant difference between the two groups in terms of conversion rate to open operation, incision margin size, hospitalization time, incidence of postoperative complications and postoperative recurrence rate (P>0.05). The 6-month survival rate of 76.7% in traditional group was lower than 92.0% in suspension group. The 12-month survival rate of 58.3% in traditional group was also lower than 78.3% in suspension group (P<0.05).

Laparoscopic right hepatectomy with a liver suspension system by using the right inferior vena cava approach could fully expose the liver cross-section, could effectively reduce bleeding, and could shorten the operation time, which is safe and effective.
