微波止血分离器在肝癌切除手术中的应用价值

Use of microwave scalpel in hepatectomy for hepatocellular carcinoma

目的分析微波止血分离器在不阻断入肝血流的肝癌切除术中的临床应用价值。方法回顾性分析2015年12月至2018年8月中山大学附属第三医院肝胆外科连续收治的126例肝细胞癌患者临床资料,其中男性111例,女性15例,年龄25-75岁。根据肝切除手术器械不同分为微波刀组(n=42)和超声刀组(n=84)。微波刀组使用微波止血分离器切除肝癌,超声刀组使用超声刀切除肝癌。比较两组术前基线资料、术中出血量、术后肝功能、术后并发症等。结果两组术前肿瘤直径、肿瘤数量、天冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)等比较,差异均无统计学意义(均P>0.05)。微波刀组术中出血量为100.0(100.0,200.0)ml,低于超声刀组的300.0(100.0,400.0)ml,差异有统计学意义(P<0.05)。微波刀组术后第1天、第3天、第7天AST、ALT均低于超声刀组,差异有统计学意义(均P<0.05)。微波刀组术后第1天、第3天白蛋白高于超声刀组,差异有统计学意义(均P<0.05)。微波刀组术后并发症发生率为4.8%(2/42),低于超声刀组并发症发生率20.2%(17/84),差异有统计学差异(P<0.05)。结论在合理掌握指征的情况下,肝细胞癌患者微波止血分离器切除肝癌组织术中出血量、术后并发症更少,肝功能损伤更轻。

Objective To study the clinical use of microwave scalpel in hepatectomy for hepatocellular carcinoma without hepatic vascular inflow occlusion.Methods A retrospective study was conducted on the clinical data of 126 consecutive patients with hepatocellular carcinoma who were treated at the Department of Hepatobiliary Surgery of the Third Affiliated Hospital of Sun Yat-sen University from December 2015 to August 2018.The patients included 111 males and 15 females,with ages which ranged from 25 to 75 years.These patients were divided into two groups by the different surgical resection methods:the microwave scalpel hepatectomy(MSH)group which employed microwave scalpels to perfonn hepatectomy(n=42),and the ultrasound scalpel hepatectomy(USH)group which employed ultrasound scalpels(n=84).The perioperative conditions which included baseline data,amount of intraoperative bleeding,liver function after operation,and morbidity of postoperative complications were compared.Results There were no significant differences in the preoperative indexes which included tumor diameter,number of tumors,levels of aspartate aminotransferase(AST)and alanine aminotransferase(ALT)behveen the 2 groups(all P>0.05).In the MSH group,the amount of intraoperative bleeding was 100.0(100.0,200.0)ml,which was significantly lower than the 300.0(100.0,400.0)ml in the USH group(P<0.05).Compared with the USH group,the levels of AST and ALT on postoperative day 1,3,7 after operation in the MSH group were significantly lower(all P<0.05),and the corresponding albumin levels were significantly higher than the USH group(P<0.05).The incidence of complications was 4.8%(2/42)in the MSH group which was significantly lower than that of 20.2%(17/84)in the USH group(P<0.05).Conclusion Microwave scalpel significantly reduced intraoperative bleeding and postoperative complications,and led to less liver functional injury.
