[Imaging and pathological features of percutaneous cryosurgery on normal lung evaluated in a porcine mode].
Lung cancer is one of the most commonly occurring malignancies and frequent causes of death in the world. Cryoablation is a safe and alternative treatment for unresectable lung cancer. Due to the lung being gas-containing organ and different from solid organs such as liver and pancreas, it is difficult to achieve the freezing range of beyond the tumor edge 1 cm safety border. The aim of this study is to examine the effect of different numbers of freeze cycles on the effectiveness of cryoablation on normal lung tissue and to create an operation guideline that gives the best effect. ⋯ Percutaneous cryoablation of the lung can achieve complete ablation of target tissue. The freezing technique may be different depending on the individual circumstances of each tumor. In technology, 3 freeze-thaw cycles are recommended, and the range of cryoablation's effective diameter may be not necessarily beyond the tumor edge at least 1 cm safe border during cryosurgery.

[Initial experience on endobronchial ultrasound-guided transbronchial needle aspiration in the diagnosis and staging of lung cancer].
It has been proven that endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was a new minimally invasive method in the diagnosis for mediastinal lymph nodes. The aim of this study is to evaluate the diagnostic and staging yield of EBUS-TBNA for lung cancer. ⋯ EBUS-TBNA proved to be a safe procedure with a high yield for the diagnosis of lung cancer.

Review[The role of TBNA in diagnosis and treatment of lung diseases].
In the last 30 years, clinical application oftransbronchial needle aspiration (TBNA) has proved its efficiency, accuracy, safety and cost-effectiveness, particularly in diagnosing and staging lung cancer as well as in diagnosing benign diseases. The application of endobronchial ultrasound (EBUS) increased the accuracy of TBNA. ⋯ Combination of EUBS-TBNA and traditional methods (CT, PET, mediastinoscopy, et al) can improve the diagnostic rate and negative predictive value. In the future, EUBS-TBNA may have applications in both benign and malignant lung diseases as a routine examination.

[Role of endobronchial ultrasound-guided transbronchial needle aspiration in the diagnosis of bronchogenic carcinoma].
The aim of this study is to evaluate diagnostic yield and the safety of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis ofbronchogenic carcinoma. ⋯ EBUSTBNA seemed a safe and effective technique in making bronchogenic carcinoma diagnosis for mediastinal/hilar LNs and intra-pulmonary masses.
