RESUMEN
Objective To explore the clinical treatment strategies of laparoscopic hepatocellular carcinoma ablation for patients with severe cirrhosis background.Methods We analyzed the clinical data of 430 patients and analyzed the indications,key techniques,efficacy and safety of laparoscopic hepatocellular carcinoma ablation for patients with severe cirrhosis background,and summarized the related experiences.Results The first complete ablation rate for the entire cohort was 94％,the 2-year local recurrence rate was 2.8％.No significant complications were found postoperatively.Conclusions Laparoscopic hepatocellular carcinoma ablation is a minimally invasive,safe and effective treatment strategy for patients with small cancer under severe cirrhosis background.Especially when the tumor is located in the " high-risk parts" for ablation,it could be a preferred method for pre-transplant treatment of these patients.
