Endobronchial ultrasound-guided transbronchial needle aspiration of mediastinal lymphadenopathy: effect of the learning curve.
This study aimed to evaluate the learning curve and efficacy of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the examination of mediastinal or hilar lymph nodes suspected of having cancer or of benign disease such as sarcoidosis. A success-adjusted cumulative sum model was used to evaluate the learning curve for diagnostic rates and operation time. A total of 99 patients (77 men and 22 women) who underwent EBUS-TBNA from April 2011 to March 2012 in a single centre were analysed retrospectively. ⋯ The sensitivity, specificity, and positive and negative predictive values and diagnostic accuracy for EBUS-TBNA were 80, 100, 100, 87.1 and 91.5%, respectively. According to the learning curve analysis, the ability to perform EBUS required performing approximately 37 procedures for the trials. In conclusion, more successful results are obtained after a certain learning curve, as is the case for every other invasive procedure.

Randomized Controlled Trial Comparative StudyLow protein content of drainage fluid is a good predictor for earlier chest tube removal after lobectomy.
Owing to the great absorption capability of the pleura for transudates, the protein content of draining pleural fluid may be considered as a more adequate determinant than its daily draining amount in the decision-making for earlier chest tube removal. In an a priori pilot study, we observed that the initially draining protein-rich exudate converts to a transudate quickly in most patients after lobectomies. Thus, chest tubes draining high-volume but low-protein fluids can safely be removed earlier in the absence of an air leak. This randomized study aims to investigate the validity and clinical applicability of this hypothesis as well as its influence on the timing for chest tube removal and earlier discharge after lobectomy. ⋯ Regardless of the daily drainage, chest tubes can safely be removed earlier than anticipated in most patients after lobectomy if the protein content of the draining fluid is low.

Comparative StudyPartly solid pulmonary nodules: waiting for change or surgery outright?
It has been assumed that if the prognosis and rate of lymph node metastases differ between two groups of patients being followed up for partly solid tumours, those with an increased solid component and those without change, these differences can help to decide on the time of surgery for patients with partly solid tumours. Therefore, this study compared the differences in pathological results and prognosis after surgical resection between patients with no change and and those with change in partly solid tumours during the preoperative period. ⋯ The pathological results and prognosis of lung cancer patients with persistent partly solid tumours who develop changes in their lesions after a certain period of follow-up time were not different from those of patients who did not develop any changes in the lesions. Therefore, surgery can be deferred until those lesions demonstrate changes in size or growth in their solid component when the overall size of ground-glass opacity (GGO) is less than 3 cm and the proportion of GGO is greater than 50%.

Case ReportsSingle-port thoracoscopic lobectomy in a nonintubated patient: the least invasive procedure for major lung resection?
General anaesthesia with single-lung ventilation was always considered a condition for thoracoscopic major pulmonary resections. However, nonintubated thoracoscopic lobectomy has been reported recently by using conventional video-assisted thoracoscopic surgery (VATS), epidural anaesthesia and vagus blockade. Here, we present a technique that reduces the surgical access trauma even more: single-incision VATS approach with no need for epidural or vagus blockade in a nonintubated patient. ⋯ Single-port video-assisted thoracoscopic lobectomy in nonintubated patients seems to be feasible and safe, and probably represents the least invasive approach to lobectomy. Further studies are necessary to evaluate the results with a series of patients.

Case ReportsThoracoscopic anatomical subsegmentectomy of the right S2b + S3 using a 3D printing model with rapid prototyping.
Thoracoscopic segmentectomies and subsegmentectomies are more difficult than lobectomy because of the complexity of the procedure; therefore, preoperative decision-making and surgical procedure planning are essential. In the literature, we could successfully perform thoracoscopic anatomical subsegmentectomy of the right S2b + S3 using a 3D printing model with rapid prototyping. This innovative surgical support model is extremely useful for planning a surgical procedure and identifying the surgical margin.
