According to the different surgical treatment methods, they were divided into the study group and the control group, each group with 32 cases. The study group was treated with single-operation-hole thoracoscopic pulmonary nodule resection, and the control group was treated with conventional multi-operation-holes thoracoscopic pulmonary nodule resection. The clinical efficacy of the two groups was compared. Results: The postoperative drainage time, intraoperative blood loss, hospitalization time, postoperative drainage volume and hospitalization cost of the study group were significantly better than those of the control group (P<0.05), and there were no significant differences between the two groups in terms of the duration of operation and the incidence of adverse reactions (such as postoperative pulmonary atelectasis and pulmonary infection) (P>0.05). There was no difference in lung function between the two groups before operation (P>0.05). Compared with the control group, the lung function indexes of the postoperative study group were significantly improved (P<0.05). There was no difference in the overall survival rate and tumor-free survival rate of the two groups after operation for half a year (P>0.05). The VAS scores of the study group were significantly lower than those of the control group on the 1st and 3rd day after operation (P<0.05). There was no difference in the quality of life between the two groups before treatment (P>0.05), but the overall health status, physiological feature, physiological function, physical pain and energy of the patients in the study group after treatment were significantly higher than those in the control group (P<0.05), but there was no significant difference in social function, emotional function and mental health (P>0.05).Conclusions: Single-operation-hole thoracoscopic surgery is effective in the treatment of elderly solitary pulmonary nodules. It can not only accelerate the recovery of patients but also improve their lung function, without affecting the prognosis of patients, which can improve their quality of life. It is worthy of clinical application, but should strictly control the indications for surgery.展开更多

This study aimed to compare the results of VATS thymectomy and open thymectomy and to identify the prognostic factors after thymectomy. Methods The clinical data of 187 consecutive thymectomies performed between July 2000 and December 2009 were retrospectively reviewed; 75 open thymectomies and 112 VATS thymectomies. Clinical efficacy and variables influencing outcome were assessed by Kaplan-Meier survival curves and Cox proportional hazards regression analysis. Results The operative blood loss in the VATS group was significantly less than that in the open group （（62.14＋55.43） ml vs. （137.87＋165.25） ml, P 〈0.05）. The postoperative crisis rate increased with the severity of preoperative MG and the prescription dose of anticholinesterase. Complete follow-up information of patients more than 12 months after the thymectomy was obtained on 151 cases, 89 cases from the VATS group and 62 cases from the open group, with a mean follow-up period of 59.3 months, range from 12 to 117 months. Complete stable remission （CSR） was the end point for evaluation of the treatment results. The overall five-year CSR rate was 57.5%. Two good prognostic factors were identified; preoperative prescription of anticholinesterase alone （P=0.035） and non-thymomatous MG （P=0.003）. The five-year CSR rate of the ocular type of MG reached a high level of 67.4%. Conclusions Thymectomy can achieve good long-term CSR in MG, and VATS is an ideal alternative method. High-dose prescription of anticholinesterase and the advanced stage by Myasthenia Gravis Foundation of America （MGFA） classification have higher risks of postoperative crisis. Preoperative prescription of anticholinesterase alone and non-thymomatous MG are good prognostic factors. Thymectomy should also be considered for the ocular tvioe of MG.展开更多
