ObjectiveTo explore the application of the technique of liver venous deprivation (LVD) for two-stage radical hepatectomy in patient with liver cancer underlying hepatitis B virus infection.MethodsA 53 years old patient diagnosed with central primary liver cancer (Ⅴ/Ⅷ segment) could not receive standard right hepatectomy since his future liver remnant was insufficient, so the LVD was performed to induce FLR growth. The general condition and CT scan were repeated at 1-, 2- and 3-week after LVD, the FLR and FLR weigh/ body weight ratio were calculated.ResultsThe FLR and FLR weight/body weight ratio before LVD were 24.2% and 0.459%, the FLR at 1-, 2- and 3-week after LVD were 29.5%, 38.3% and 44.4% respectively, the FLR weight/body weight were 0.545%, 0.707% and 0.820% at 1-, 2- and 3-week after LVD. The standard right hepatectomy was undertaken successfully at 25 days after LVD and discharged safely.ConclusionThe LVD technique could induce a rapid and large FLR volume and offer opportunity for patients with insufficient FLR to receive two-stage radical hepatectomy, is a novel method to induce FLR growth effectively.
ObjectiveTo explore the safety and efficacy of preoperative liver regeneration and then two-stage liver resection for advanced hepatic alveolar echinococcosis (HAE) patients pre-evaluating insufficient future liver remnant (FLR) after resection. MethodThe clinical data of the advanced HAE patients who were expected to have insufficient FLR after liver resection and underwent two-step liver resection in the Sichuan Provincial People’s Hospital from December 2016 to December 2022 were retrospectively collected and summarized. ResultsA total of 11 patients with advanced HAE pathologically confirmed were collected. Among them, 2 cases underwent portal vein embolization (PVE), 2 cases underwent liver vein deprivation (LVD), and 7 cases underwent associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) to promote residual liver regeneration in the first stage. The FLR/standard liver volume (SLV) exceeded the surgical requirement standard of 40%. Then the ex-vivo liver resection and autotransplantation, or directly radical liver resection was performed in the second stage. Only one patient underwent surgery to remove packed gauze on day 3 postoperatively due to massive intraoperative bleeding (approximately 4 000 mL). The median (P25, P75) follow-up time after surgery was 36 (15, 75) months, only one case was found to relapse at the third year after surgery and underwent surgical resection again, and the rest patients had no recurrence, long-term complications, or death. ConclusionsBased on the results from these cases, applying PVE, LVD, or ALPPS in the patients with advanced HAE who were expected to have insufficient FLR after resection aids to residual liver regeneration, creating conditions for the second stage radical resection. The second stage treatment including ex-vivo liver resection and autotransplantation or directly radical liver resection could achieve good results and is feasible and safe, which brings a hope of survival for the advanced HAE patients who could not previously undergo curative resection. However, this treatment strategy still incurs high costs and requires further optimization in the future.
