Persistent air leaks (PAL) is a common complications after pulmonary operation. Risk factors include operationrelated and general factors. At present， stapling device, staple line buttressing, pleural tent, and pneumoperitoneum are the main methods for management. This review described the definition, risk factors, qualitative and quantitative evaluation, and recent progress in air leak prevention and management.
Surgical management of non-small cell lung cancer (NSCLC) invading chest wall is the combination of pulmonary resection, lymphadenectomy and chest wall resection and reconstruction. Hitherto the surgical procedures include combination of thoracotomy and video-assisted thoracoscopic surgery (VATS), thoracotomy, and VATS. The result of the surgery leads to a defect in the chest wall. Therefore, the requirements of the technique and material are relatively high with no consensual standard. This review describes the definitions, indications, materials, prognostic factors, and recent progress in surgical techniques.
Lung ground glass opacity (GGO), which is associated with the pathology of the lung adenocarcinoma, is drawing more and more attention with the increased detection rate. However, it is still in the research stage for the imaging interpretation of GGO lesions. In this paper, we reviewed and analyzed the new classification of lung adenocarcinoma corresponding to the interpretation of GGO imaging feature, which emphasizes on how to determine the GGO lesions comprehensively and quantitative determination of the invasive extent of GGO.
With the wide utilization of high-resolution computed tomography (HRCT) in the lung cancer screening, patients detected with pulmonary ground-glass nodules (GGNs) have increased over time and account for a large proportion of all thoracic diseases. Because of its less invasiveness and fast recovery, video-assisted thoracoscopic surgery (VATS) is currently the first choice of surgical approach to lung nodule resection. However, GGNs are usually difficult to recognize during VATS, and failure of nodule localization would result in conversion to thoracotomy or extended lung resection. In order to cope with this problem, a series of approaches for pulmonary nodule localization have developed in the last few years. This article aims to summarize the reported methods of lung nodule localization and analyze its corresponding pros and cons, in order to help thoracic surgeons to choose appropriate localization method in different clinical conditions.
With the development of thin section axial computed tomography scan, the detection rate of pulmonary ground-glass nodules (GGN) continues increasing. GGN has a special natural growth history: pure ground-glass nodules (PGGN) smaller than 10 mm can hold steady for a long term, surgery resection is unnecessary, patients need regular follow up. Larger part solid ground-glass nodules (PSN) with a solid component can be malignant early stage lung cancer, which requires early surgery intervention. Establishment of a standard definition of GGN growth, investments in the long term natural growth history of GGN, validation of the clinical, radiology and genetic risk factors would be beneficial for the management of GGN patients.
Quality control of general thoracic surgery contains many links including the qualification and technical conditions of medical institutions, preoperative diagnostic system, surgery, postoperative management, pathological diagnosis and follow-up. Standards of quality control should be based on evidence-based medicine, and general rules with detailed criteria. As one of the core concepts of quality control, fine management is ought to strictly follow clinical practice guideline of thoracic surgery, to be clear with quality standards of each key link in clinical pathway, and to improve the clinical quality control system that combines self-evaluation and supervision and inspection.
Acute pulmonary embolism (PE) is a common disorder with significant morbidity and mortality in patients who underwent pulmonary ground-glass nodules (GGN) resection. We should make efforts to increase surgeons' awareness of risk factors of PE and their understanding of the effectiveness of prevention strategies. Using the optimal risk assessment model to identify high-risk patients and give them the individualized prophylaxis. Early diagnosis and accurate risk stratification is mandatory to reduce the rates of PE, to decrease health care costs and shorten the length of stay. This article summarizes the risk factors, diagnostic process, risk assessment models, prophylaxis and therapy for the PE patients who underwent GGN resection.
