Successful step-by-step diagnosis and management of expiratory central airway collapse.

A 45-year-old woman with recurrent dyspnea for 40 years was previously diagnosed with bronchial asthma and spasmodic dysphonia. On admission, the patient was diagnosed with expiratory central airway collapse (ECAC) due to expiratory dynamic airway collapse based on radiographic examination, chest computed tomography, and bronchoscopy. After continuous positive airway pressure and temporal airway stenting, surgical tracheobronchoplasty and tracheal membranous portion reinforcement using polypropylene mesh successfully relieved the respiratory symptoms.

Virtual-assisted lung mapping using dual staining with indocyanine green and indigo carmine enhanced marking detectability.

Background: Virtual-assisted lung mapping (VAL-MAP) is a preoperative bronchoscopic multispot dye-marking procedure to facilitate sublobar lung resection for unidentifiable lung nodules. To increase detectable markings, we performed VAL-MAP using dual staining (VAL-MAP DS) with indocyanine green (ICG) and indigo carmine. This study was designed to evaluate the efficacy and safety of the modified technique.

[The Significance of Surgical Biopsy in Case of the Resistance to Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors for the Treatment of Postoperative Recurrence of Lung Cancer].

To evaluate the clinical features of patients who developed resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) administered for postoperative recurrence of lung cancer, we assessed eight patients who underwent surgical biopsy or sampling for the detection of T790M mutation under general anesthesia from 2017 to 2019 in our hospital. All 8 patients had undergone lobectomy with nodal dissection for lung cancer of pathological stageⅠB/Ⅲ/Ⅳa (4/3/1 patients). The median disease-free survival was 29 months (range:11~110 months).

[Lung Cancer Accompanied by Sarcoidosis with Mediastinal and Bilateral Hilar Lymphadenopathy;Report of a Case].

A 64-year-old woman with complete atrioventricular block caused by sarcoidosis was emergently placed a pacemaker. A 10 mm nodule in the left upper lobe of the lung and the mediastinal and bilateral hilar lymphadenopathy was detected through chest computed tomography. To establish the diagnosis, resection of the tumor and #4L was performed.
