This paper describes the advantages and disadvantages of radiofrequency ablation from the current situation of hepatocellular carcinoma treatment, radiofrequency ablation treatment, the efficacy of radiofrequency ablation in hepatocellular carcinoma, the shortcomings of radiofrequency ablation treatment, and the experience of the author’s treatment team. For the treatment of liver cancer, we should not blindly pursue minimally invasive and ignore the principle of radical resection, nor blindly pursue radical resection and ignore the risk of surgery. We should choose reasonable treatment methods, let the patient get the best treatment.
Objective To investigate the safety and efficacy of completely thoracoscopic lobectomy and the indications of this procedure. Methods Between Sep. 2006 and Jun. 2008, 100 consecutive patients（46 men，54 women, median age60.1±12.5 years，range from 18 to 82 years) underwent completely thoracoscopic lobectomy. All candidates were either peripheral pulmonary nodules suspected of lung cancer (85 pts.) or benign lesions (15 pts.) localized within single lobe who needed to receive lobectomy. The lobectomy was completed through three tiny incisions in the intercostal space. Anatomic lobectomies were carried out in all cases and systemic lymph node dissection was performed in malignancies. This group consisted of lobectomies of right upper lobe (n=25), right middle lobe (n=14), right lower lobe (n=22), left upper lobe (n=18), and left lower lobe (n=21). Results All procedures were successfully completed except for 3 conversions to thoracotomy. Postoperative diagnosis were primary lung cancer (n=81), lymphoma (n=1), metastasis of clear cell carcinoma from kidney (n=1), and, benign lesions (n=17). Five patients had mild complications in which two had atelectasis, one needed temperately echanical ventilation, one had pneumonia and one had chylothorax. All were treated conservatively without reoperation. No operative mortality or serious complications occurred in this group. The operative duration was 186.4±52.9min (range from 60 to 300 minutes). The blood loss was 233.9±275.9ml（range from 50 to 750ml）, and only one case needed blood transfusion. Chest drainage time was 7.1±3.0 days. Postoperative hospital stay was 9.5±3.2 days. Followedup time was for 1 to 27 months, metastasis happened in two patients with primary lung cancer 15 and 3 months separately after operation. Conclusion The completely thoracoscopic lobectomy is a safe and feasible surgical procedure with minimal invasiveness. The advocated indications include selected peripheral typed early stage lung cancer and benign pulmonary lesions which need lobectomy.
目的：探讨腹腔镜诊治附件包块的有效性与安全性。方法:回顾性分析四川大学华西第二医院2004年1月至2005年12月妇科收治的1356例附件包块行腹腔镜治疗的病例。结果:手术适应证主要为异位妊娠、卵巢宫内膜囊肿及卵巢良性畸胎瘤，手术方式主要为输卵管造口取胚术、输卵管切除术、卵巢囊肿剥除术及患侧附件切除术，手术成功率98.45%,无严重并发症发生。术中发现可疑病例78例（5.8％），病理检查提示交界性及低度恶性包块共9例（0.66％），其中4例在腹腔镜下完成手术。既往有腹部手术史85例，77例在腹腔镜下完成手术。结论：腹腔镜技术在诊治妇科良性附件占位方面是安全有效的。
ObjectiveTo summarize the progress in the application of ankle and hindfoot arthrodesis. MethodThe domestic and foreign related literature about the application of ankle and hindfoot arthrodesis was reviewed, summarized, and analyzed. ResultsAnkle and hindfoot arthrodesis include the multi-joint fusion and the single joint fusion, and they involve tibiotalar joint, subtalar joint, talonavicular joint, and calcaneocuboid joint. The methods of fixation include screw, plate, intramedullary nail, and external fixation. ConclusionsDifferent terminal illnesses of ankle and hindfoot have different choices in both the fusion location and the method of fixation, appropriate program for therapeutic purposes can also alleviate complication simultaneously.
