Objective To analyze the effect of surgical position nursing for radiofrequency ablation in posterior root ganglion in lumbar spinal nerve guided by MRI in lateral prone position．Methods Sixty-two patients with lumbar disc herniation hospitalized in Liwan Central Hospital of Guangzhou from September 2018 to December 2020 were randomly divided into two groups（the lateral prone position group and the prone position group,31 patients in each group）．The lateral prone position group used the lateral prone position with about 30 degrees elevation of the affected side,and the prone position group used the standard prone position for operation．Operating time,surgical complications,surgical position related complications,and operator satisfaction evaluation of surgical field exposure were recorded in both groups．Results All patients completed the operation successfully．No surgical complications such as bleeding,infection,lower limb paralysis,aggravated nerve injury or organ injury were found in the two groups．No surgical position related complications such as intraocular pressure raising,brachial plexus injury or pressure ulcers in both the groups either．The operation time was（60.65±12.45）min in the lateral prone position group and（70.58±10.25）min in the standard prone position group,respectively,and the difference was statistically significant（t=3.429,P=0.001）．The surgeon’s satisfaction evaluation of the surgical field exposure was much higher in the lateral prone position group（93.55%）compared with the standard prone position group（77.42%）,and the difference was statistically significant（χ²=4.29,P=0.038）．Conclusions Radiofrequency ablation in posterior root ganglion of lumbar spinal nerve guided by MRI in lateral prone position is safe and effective．Good surgical position nursing can effectively prevent complications．

目的 探究腔内微波消融(EMA)联合泡沫硬化剂治疗与腔内射频消融(RFA)联合泡沫硬化剂治疗下肢静脉曲张的临床疗效和并发症情况。方法 回顾性选择收集106例下肢静脉曲张患者的临床资料,其中54例患者(观察组)接受EMA联合泡沫硬化剂治疗,52例患者(对照组)接受RFA联合泡沫硬化剂治疗。比较2组患者相关临床指标及并发症发生情况。结果 观察组手术时间(34.92±2.35)min,对照组手术时间(46.33±2.71)min,观察组手术时间较短,差异有统计学意义(P＜0.05),其余手术参数差异不明显(P＞0.05)。观察组的住院费用(21 063.74±850.47)元,对照组住院费用(23 312.40±1 035.86)元,观察组住院费用较低,有统计学差异(P＜0.05)。2组间并发症发生率、总有效率和总满意度均无显著差异。对比2组患者手术前和手术治疗后1年的静脉临床严重程度评分、阿伯丁静脉曲张问卷评分,组间对比没有统计学差异(P＞0.05);而在患者手术1年之后的静脉临床严重程度评分、阿伯丁静脉曲张问卷评分均呈现出明显的下降趋势(P＜0.05)。结论 微波消融是有效治疗下肢静脉曲张的术式,与射频消融比较,具有同样良好的短期效果;微波消融所需的手术时间较短且费用较低。

Objective To compare the clinical efficacy and complications between endovascular microwave ablation (EMA) combined with foam sclerotherapy and radiofrequency ablation (RFA) combined with foam sclerotherapy in patients with varicose veins of lower extremity. Methods A total of 106 patients with varicose veins of lower extremity were included in the retrospective study.Among them, 54 patients (observation group) were treated with EMA combined with foam sclerotherapy, and 52 patients (control group) were treated with RFA combined with foam sclerotherapy.The related clinical indexes and complications between the two groups were compared. Results The observation group had a shorter procedure time than the control group (34.92±2.35 minutes vs 46.33±2.71 minutes, P＜0.05), and no significant differences were observed in the other procedure parameters.The hospitalization cost was (21063.74±850.47) yuan for the observation group and (23312.40±1035.86) yuan for the control group, and the hospitalization cost of the observation group was lower(P＜0.05).No significant differences were found in the total effective rate,total satisfaction and complication rate between the two groups.Comparison of venous clinical severity score (VCSS) and Aberdeen varicose vein questionnaire (AVVQ) scores before and one year after operation between the two groups showed no statistical differences (P＞0.05). While the VCSS and AVVQ scores of the patients showed a significant downward trend one year after operation (P＜0.05). Conclusions Microwave ablation is an effective treatment for varicose veins in the lower extremity, which has the same good short-term effect as radiofrequency ablation. Microwave ablation requires a shorter operation time and less cost.

目的 探讨超声引导下射频消融术治疗肝癌的资料,评价其术后局部复发的影响因素,为临床应用提供参考依据。方法 回顾性分析2010年7月—2012年7月我院进行超声引导下射频消融治疗肝癌80例患者的临床资料,通过统计学软件,明确射频消融术的疗效,通过单因素分析中的χ²检验和logistic线性回归分析等方法分析射频消融治疗肝癌局部复发的主要危险因素。结果 80例肝癌患者行超声引导下射频消融术治疗的次数共为94次,12例肝癌患者接受RFA治疗的次数≥2次,94次肝癌射频消融术处理病灶共为101个,完全消融共为68例(85.0%),不完全消融12例(15.0%);所研究病例瘤体个数按≤3 cm、3～5 cm、>5 cm分组总数分别为55、34、12,其完全消融率分别为89.09%、79.41%、66.67%;运用多因素统计分析,结果显示肝硬化、肝炎史以及血管癌栓形成是影响肝癌患者射频消融术后局部复发的独立因素。结论 RFA治疗肝癌是一种疗效满意的局部微创治疗手段,肝硬化、肝炎史、血管癌栓形成是影响肝癌患者术后局部复发的独立高危因素。

Objective To provide reference for clinical application, we investigated the data of ultrasound-guided radiofrequency ablation RFA in the treatment of hepatocellular carcinoma and evaluated the influencing factors of local recurrence after operation. Methods The clinical data of 80 patients with hepatocellular carcinoma treated with ultrasound-guided radiofrequency ablation from July 2010 to July 2012 in our hospital were analyzed retrospectively. The efficacy of radiofrequency ablation was determined by statistical software analysis. We analyzed the main risk factors of local recurrence of hepatocellular carcinoma treated with radiofrequency ablation by χ² test and logistic linear regression analysis in univariate analysis. Results The frequency of ultrasound-guided radiofrequency ablation in 80 patients with hepatocellular carcinoma was 94 times and a total of 101 lesions were treated. Among them, 12 patients with hepatocellular carcinoma were treated with RFA more than 2 times. In 80 patients with hepatocellular carcinoma treated with RFA, 68 cases (85.0%)underwent complete ablation and 12 cases (15.0%)underwent incomplete ablation. The treated lesions were divided into 55, 34 and 12 lesions respectively, according to the size of≤ 3cm, 3 ≤ 5cm,>5cm. And the complete ablation rates were 89.09%, 79.41% and 66.67% respectively. Multivariate statistical analysis showed that liver cirrhosis, hepatitis history and vascular tumor thrombus formation were independent factors for the local recurrence of patients with hepatocellular carcinoma after radiofrequency ablation. Conclusion RFA treatment of hepatocellular carcinoma is a local minimally invasive treatment with satisfactory efficacy. Cirrhosis, hepatitis history and vascular tumor thrombosis are independent high risk factors for the local recurrence of patients with hepatocellular carcinoma.
