A novel treatment on small hepatocellular carcinoma adjacent to large vessels by ultrasound assisted precision microwave ablation

Abstract

Abstract: Objective To observe the effect of a novel ultrasound technology assisted precise microwave ablation for small hepatocellular carcinoma adjacent to large vessels.Methods A total of 76 patients with small hepatocellular carcinoma near large blood vessels who were admitted to Xi'an Baoshihua Changqing Hospital were selected and divided into a control group (with surgical resection, n=36 cases) and a study group (with microwave ablation treatment assisted by new technology of ultrasound, n=40 cases) according to the different surgical regimes selected. The operation time, hospital stay, incidence of complications and 1month postoperative resection rate were compared between the two groups. The patients were followed up for 1 year, and the incidence of tumor progression and survival at 1 year after surgery were compared.Results The operation time and hospital stay in the study group were shorter than those of the control group [(92.45±15.28) min vs (138.41±28.35) min, and (6.12±1.47) d vs (10.06±2.13)d, respectively] (t=8.918, 9.463, all P<0.05). The incidence of complications during hospitalization in the study group (2.78% vs 17.50%) was lower (χ²=4.360, P=0.037). The surgical resection rates of the control group and the study group (2.78% vs 17.50%) were similar (χ²=1.849, P=0.174). The incidence of tumor progression at 1 year after operation in the control group and the study group was similar (16.67% vs 17.50%) (χ²=0.009, P=0.923). The 1-year survival rates of the control group and the study group were similar (83.33% vs 80.00%) (χ²=0.165, P=0.684).Conclusion The treatment of ultrasound technology assisted precise microwave ablation for small liver cancer adjacent to large vessels can achieve the same therapeutic effect as surgical resection, with shorter operation time and hospital stay, as well as relatively less complications.
