RESUMO
@#Uniportal video-assisted thoracic surgery (UniVATS) is a significant approach of mini-invasive surgery for lung cancer. UniVATS was first used for treatment of lung cancer in 2010. The European consensus and the Chinese consensus were published in 2019 and 2020 respectively. The latest Chinese consensus included the definition of UniVATS, indications for lung cancer treatment, safety and feasibility, surgical skills, learning curve, short-term and long-term results, providing suggestions for the standardization of uniportal video-assisted thoracic surgery, which are essential to improve the quality of surgery and reduce the incidence of related complications. The Chinese consensus also summarized the current status of subxiphoid UniVATS and non-intubated UniVATS for lung cancer. Considering the technical difficulties and challenges, the application of both technologies in clinical treatment has certain limitation. This article aims to give an interpretation of the results of the Chinese consensus and the similarities and to compare the differences with the European consensus, and to provide a reference for the majority of thoracic surgery colleagues.
RESUMO
@#Objective To analyze the risk factors for complications after robotic segmentectomy. Methods Clinical data of 207 patients undergoing robot-assisted anatomical segmentectomy in our hospital from June 2015 to July 2019 were retrospectively analyzed, including 69 males and 138 females with a median age of 54.0 years. The relationship between clinicopathological factors and prolonged air leakage, pleural effusion, and pulmonary infection after surgery was analyzed. Results After robot-assisted segmentectomy, 20 (9.7%) patients developed prolonged air leakage (>5 d), 17 (8.2%) patients developed pleural effusion, and 4 (1.9%) patients developed pulmonary infection. Univariate logistic regression showed that body mass index (BMI, P=0.018), FEV1% (P=0.024), number of N1 lymph nodes resection (P=0.008) were related to prolonged air leakage after robot-assisted segmentectomy. Benign lesion was a risk factor for pleural effusion (P=0.013). The number of lymph node sampling stations was significantly related to the incidence of pulmonary infection (P=0.035). Multivariate logistic analysis showed that the BMI (OR=0.73, P=0.012) and N1 lymph node sampling (OR=1.38, P=0.001) had a negative and positive relationship with prolonged air leakage after robot-assisted segmentectomy, respectively. Conclusion The incidence of pulmonary complications after robot-assisted segmentectomy is low. The lower BMI and more N1 lymph node sampling is, the greater probability of prolonged air leakage is. Benign lesions and more lymph node sampling stations are risk factors for pleural effusion and lung infection, respectively. Attention should be paid to the prevention and treatment of perioperative complications for patients with such risk factors.
RESUMO
Objective To study the appearances of split cord malformation(SCM)and evaluate the diagnostic value of CT for SCM.Methods Clinical and CT data of 48 cases with SCM were analyzed retrospectively ,21 were males and 27 were females,ranged from 1 day to 8 years with a mean of 11.6 months. All cases evaluated by plain CT with coronal and sagittal reconstructions.Results Type I accounted 75%, consisted of two hemicords, each contained in its dural tube and separated by a rigid median septum .TypeⅡaccounted 25%, consisted two hemicords contained in a single dural sac separated by a non-rigid, fibrous median septum. Associated abnormalities: tethered cord syndrome(n=38), syringomyelia(n=9), intradural lipomas(n=10), meningocele(n=18).Conclusion CT can clearly demostrate the position, the septum and the shape of the SCM, as well as associated abnormalities.
