Microwave ablation guided by real-time contrast-enhanced ultrasound and fusion image in treatment of patients with small liver cancer
Objective To study the value of microwave ablation guided by real-time contrast-enhanced ultrasound and fusion image in the treatment of patients with small liver cancer.Methods A total of 84 patients with small liver cancer admitted to Huangshi Central Hospital from May 2019 to November 2020 were selected as the study samples.According to the treatment methods,they were divided into an observation group,taking microwave ablation guided by real-time contrast ultrasound and fusion image,and a control group,taking surgical treatment,with 42 cases each group.There were 23 males and 19 females in the observation group;they were(44.86±3.46)years old;there were 58 lesions;the longest lesion diameter was(1.56±1.07)cm.There were 25 males and 17 females in the control group;they were(43.60±3.50)years old;there were 61 lesions;the longest lesion diameter was(1.62±1.02)cm.The operation times,hospitalization times,and incidences of complications were compared between the two groups.The patients were followed up until November 2022.The disease progress and survival and death within 2 years were compared between the two groups.t,x2,and Log-rank tests were applied.Results The operation time and hospitalization time in the observation group were shorter than those in the control group[(92.37±19.43)min vs.(142.16±21.83)min and(4.37±2.26)d vs.(9.42±2.81)d],with statistical differences between the two groups(t=11.041 and 9.076;both P＜0.001).The total incidence of complications in the observation group was lower than that in the control group[9.52％(4/42)vs.26.19％(11/42);x2=3.977;P=0.046].The local progression rate,mortality rate,and 2-year cumulative survival rate of the observation group were 35.71％(15/42),28.57％(12/42),and 70.00％(28/40),respectively;and those of the control group were 33.33％(14/42),30.95％(13/42),and 68.29％(28/41),respectively;there were no statistical differences(x2=0.054 and 0.067;Log-rank=0.084;all P＞0.05).Conclusion Microwave ablation guided by real-time contrast-enhanced ultrasound and fusion image in the treatment of patients with small liver cancer is of great clinical value,minimally invasive,and safe.
