Observational Study
Undiagnosed Obstructive Sleep Apnea and Postoperative Outcomes: A Prospective Observational Study.
The prevalence of undiagnosed obstructive sleep apnea (OSA) during preoperative evaluation and the best method to screen OSA and its association with postoperative complications remain unclear. ⋯ Unrecognized OSA is common in preoperative patients and is independently associated with postoperative complications. The STOP-BANG questionnaire had a lower performance in the diagnosis of OSA in a South Indian population than the level III sleep study.

Gastroesophageal reflux disease is a potential risk factor for idiopathic pulmonary fibrosis (IPF) progression; however, the impact of antacid therapy (AAT) is under debate. ⋯ AAT and pirfenidone had outcomes comparable to those of pirfenidone alone in patients with IPF, underscoring the need for prospective trials to elucidate the role of AAT with or without antifibrotic drugs as a treatment for IPF.

Staging of lung cancer is essential to the treatment, which is curative only in cases of localized disease. Previous studies have suggested that endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is unnecessary when positron emission tomography-computed tomography (PET-CT) shows no mediastinal involvement. ⋯ The overall probability of a clinically relevant upstaging by EBUS-TBNA in patients judged as N0/N1 at PET-CT was 6.0%, compared to 0.9% in patients classified as N0 and 17.3% in patients classified as N1. The risk of overlooking N2/N3 disease after both PET-CT and EBUS-TBNA was 10.4%.

Capsule endoscope aspiration is an increasingly reported complication, potentially responsible for respiratory distress and asphyxia. This adverse event is primarily managed by rigid bronchoscopy when spontaneous expulsion does not occur. This complication is all the more detrimental to patients as it can delay or jeopardize further digestive exploration. We report direct repositioning of the capsule in the stomach at the same time as bronchoscopy, thus making second-line gastrointestinal endoscopy needless.

Endoscopic lung volume reduction (ELVR) is being adopted as a treatment option for carefully selected patients suffering from severe emphysema. ELVR with the one-way endobronchial Zephyr valves (EBV) has been demonstrated to improve pulmonary function, exercise capacity, and quality of life in patients with both heterogeneous and homogenous emphysema without collateral ventilation. In this "expert best practices" review, we will highlight the practical aspects of this therapy. ⋯ Pneumothorax is a common complication and typically occurs in the first 2 days following treatment. A management algorithm for pneumothorax has been previously published. Long-term sequelae from EBV therapy do occur but are easily manageable.
