目的:探讨微波刀在肝癌切除术中的临床应用价值。方法:将肝癌患者随机分成2组,微波刀组(35例)用国产ECO-100微波刀,将微波针头插入肿瘤边缘反复进行微波消融,形成切除线,然后进行肝切除。常规组(36例)进行常规肝癌切除手术。结果:微波刀组35例38个肝癌瘤体经过肿瘤边缘消融治疗,均完成了肝切除,术后无肝功能衰竭,均顺利出院。随访1年9例复发,其中3例于原肿瘤边缘复发,5例肝内其他部位复发,1例肺部转移。患者治疗后出现轻度肝功能异常的程度较常规组明显减轻。常规组术后随访1年14例复发,6例位于肿瘤边缘复发,7例肝内转移,1例脑转移。结论:肝癌手术中运用微波刀头烧灼形成切除线,然后行肝切除术具有较高的安全性,术后肝功能恢复较快,复发率较低,是可行的手术切除方法,可以改善此类患者的预后。
Objective: To explore the clinical value of microwave knife in resection of liver cancer. Methods: The patients with liver cancer were randomly divided into two groups. The microwave knife group (35 cases) was treated with a domestic ECO-100 microwave knife. The microwave needle was inserted into the tumor edge to perform microwave ablation repeatedly to form the resection line and then hepatectomy. The conventional group (36 cases) underwent conventional hepatectomy. Results: In the microwave knife group, 35 cases of 38 HCCs were treated by ablation of tumor margins. All of them underwent liver resection, and no liver failure occurred after operation. All patients were discharged smoothly. Nine cases were followed up for 1 year, of which 3 cases recurred on the edge of the original tumor, 5 cases recurred in other parts of the liver, and 1 case had lung metastases. Patients with mild liver dysfunction after treatment than the conventional group significantly reduced. In the conventional group, 14 cases were followed up for 1 year, 6 cases were located at the edge of the tumor, 7 cases were intrahepatic metastasis and 1 case was brain metastasis. Conclusion: It is a feasible surgical resection method to use cauterization of microwave cutting to form resection line in hepatocellular carcinoma and then to perform hepatectomy with high safety, fast recovery of liver function and low recurrence rate after operation, which can be improved The patient’s prognosis.
