Objective To investigate the primary peripheral non-small cell lung cancer (NSCLC) in stage T1 of TNM (UICC2011) (the tumor size≤3 cm) and to find out the lymphadenectomy way which will benefit patients most. Methods We retrospectively analyzed the clinical data of 60 patients with primary peripheral NSCLC in our hospital between November 2014 and May 2015. There were 26 males and 34 females at age of 34-76 (57.91±7.75) years. The lymph nodes dissection and metastasis were recorded. Results The total number of intrathoracic lymph nodes dissection is 1 208,with an average of 20.1, including 33 metastasis lymph nodes. The metastasis rate was 2.73%. A total of 51 patients were not found the mediastinum and hilum metastasis lymph node through the routine pathological detection method，while metastasis lymph node in section 12 and (or) 13 and (or) 14 group were found in 3 patients in our trial. The detection rate was 5.89%. For stage T1 primary peripheral NSCLC, with increasing tumor size, lymph node metastasis rate was gradually increased. The patients with solid lesions were more likely to have lymph node metastasis than those with non-solid lesions (pure ground-glass nodules or mixed ground-glass nodules) which generally did not find lymph node metastasis. Conclusion The lymph node metastasis rate in stage T1 primary peripheral NSCLC is related to the tumor size, nature, histological type, local pleural stretch in imaging. The dissection of lung lymph node (12+13+14 groups)may be able to find simple intrapulmonary lymph nodes metastasis. It is important to the selection of delineated staging and treatment program in stage T1 primary peripheral NSCLC.
Objective To investigate the security and feasibility of silk ligating for pulmonary artery in video-assisted thoracoscopic lobectomy, and to summarize the clinical skills. Methods We retrospectively analyzed the clinical data of 68 patients underwent the video-assisted thoracoscopic lobectomy from April 2013 to March 2015. There were 49 males and 19 females with the mean age of 59.6±10.3 years, ranging from 38 to 76 years. We divided the patients into an ECR60W cut-up group (31 patients) and a silk ligation group (37 patients). There were 22 males and 9 females patients with the average age of 59.3±9.9 years with ECR60W. There were 27 males and 10 females patients with the average age of 59.9±10.5 years with silk ligation. We observed the effect of hemostasis, and analyzed the amount of bleeding loss during operation, postoperative suction drainage and the cost of operation material between the two groups. Results There were 4 patients out of 68 converted to the open lobectomy, and all of them used ECR60W. The application of silk ligation for pulmo-nary artery could effectively control bleeding loss and avoid massive amount of bleeding due to the vascular tear in opera-tions. Furthermore, the application can reduce the rate of severe complications such as massive bleeding resulting from postoperative silk ligation slippage. There was a statistical difference between the two groups on the cost of operation mate-rials (P < 0.01). Conclusions Silk ligation for pulmonary artery in video-assisted thoracoscopic lobectomy is simple and prac-tical to apply. Compared with the ECR60W, it can significantly reduce the cost of operation material. It's worth to popularize in clinic.
ObjectiveTo investigate indications,technical points,and outcomes of laparoscopic liver resection in treatment for hepatic hemangioma. MethodThe clinical data of 78 patients with hepatic hemangioma underwent laparoscopic liver resection in our institute from January 2014 to December 2014 were analyzed retrospectively. ResultsSeventy-seven patients were underwent laparoscopic liver resection successfully,1 patient was conversed to open procedure.Operation method:laparoscopic anatomical liver resections were performed in 35 patients including 23 patients with left lateral segmentectomy,4 patients with left hemihepatectomy,3 patients with right hemihepatectomy,1 patient with Ⅲ segmentectomy,1 patient with Ⅵ segmentectomy,2 patients with Ⅵ and Ⅶ segmentectomy,1 patient with left lateral segmentectomy combined with Ⅵ and Ⅶ segmentectomy.Laparoscopic non-anatomical liver resection were performed in 43 patients.The operation time was (163.6 ±62.3) min,the intraoperative blood loss was (273.6±282.4) mL.No operative death occurred.One patient with postoperative functional bowel obstruction and 3 patients with pleural effusion had been recorded.All the patients recovered well.The postoperative hospital stay was (7.2±2.5) d.The results of postoperative pathology confirmed that all the tumors were hepatic cavernous hemangiomas. ConclusionsLaparoscopic liver resection for hepatic cavernous hemangioma is a safe and feasible method with small trauma,rapid recovery,cosmetic incision.Key of this technology is to strictly select surgical indications,to transect liver parenchyma along right plane,effective control of hepatic blood inflow,and properly management of cutting surface of liver.
