目的:分析采用射频消融术治疗肝脏肿瘤患者肝内感染的影响因素。方法:选取2013年4月—2015年4月间接受射频治疗的肝脏肿瘤患者85例为研究对象,分析治疗后的临床疗效及对肝内感染的影响因素。结果:治疗后患者肝内抗感染的总有效率为92.94%,1年和2年期的生存率分别为96.47%和81.18%;12例患者发生感染,其中转移性肿瘤、有腹部手术史、肿瘤个数多、肿瘤直径>3 cm的患者感染的发生率明显高于原发性肿瘤、没有腹部手术史、肿瘤单发和肿瘤直径<3 cm的患者(P<0.05)。结论:采用射频消融术疗法对肝脏肿瘤患者的临床疗效较好,并对肿瘤类型、个数、直径大小和是否有腹部手术史均为肝内感染的重要影响因素。
OBJECTIVE: To analyze the influencing factors of intrahepatic infection in patients with liver tumors treated with radiofrequency catheter ablation. Methods: From April 2013 to April 2015, 85 patients with hepatic tumors treated by RFA were selected as the research object, and the clinical efficacy and factors affecting the intrahepatic infection were analyzed. Results: After treatment, the total effective rate of intrahepatic anti-infective was 92.94%, and the survival rates at 1-year and 2-year were 96.47% and 81.18% respectively. Twelve patients developed infection, including metastatic tumors, history of abdominal surgery, The number of patients with tumors> 3 cm in diameter was significantly higher than that in primary tumors, no history of abdominal surgery, single tumors and tumors <3 cm in diameter (P <0.05). Conclusion: The radiofrequency ablation therapy has a good clinical curative effect on patients with liver tumors. The type of tumor, the number of patients, the diameter and the history of abdominal surgery are important factors of intrahepatic infection.
