Background: Prolonged pulmonary air leaks (PALs) are associated with increased morbidity and extended hospital stay. We sought to investigate the role of bronchoscopic placement of 1-way valves in treating this condition.
Methods: We queried a prospectively maintained database of patients with PAL lasting more than 7 days at a tertiary medical center. Main outcome measures included duration of chest tube placement and hospital stay before and after valve deployment.
Results: Sixteen patients were eligible to be enrolled from September 2012 through December 2014. One patient refused to give consent, and in 4 patients, the source of air leak could not be identified with bronchoscopic balloon occlusion. Eleven patients (9 men; mean age, 65 ± 15 years) underwent bronchoscopic valve deployment. Eight patients had postoperative PAL and 3 had a secondary spontaneous pneumothorax. The mean duration of air leak before valve deployment was 16 ± 12 days, and the mean number of implanted valves was 1.9 (median, 2). Mean duration of hospital stay before and after valve deployment was 18 and 9 days, respectively (P = .03). Patients who had more than a 50% decrease in air leak on digital monitoring had the thoracostomy tube removed within 3-6 days. There were no procedural complications related to deployment or removal of the valves.
Conclusions: Bronchoscopic placement of 1-way valves is a safe procedure that could help manage patients with prolonged PAL. A prospective randomized trial with cost-efficiency analysis is necessary to better define the role of this bronchoscopic intervention and demonstrate its effect on air leak duration.

Noninflammatory Causes of Pulmonary Edema During Ex Vivo Lung Perfusion.
Ann Thorac Surg Short Rep

Toronto Lung Transplant Program, Toronto General Hospital, Toronto, Canada.
Ex vivo lung perfusion (EVLP) is used to evaluate donor lungs prior to lung transplantation. Development of pulmonary edema during EVLP is generally thought to represent inflammatory breakdown of the air-fluid barrier and these lungs are declined for transplant. We present the case of a donor lung that underwent stapled wedge resection during cold storage for air leak and the subsequent development of profound (∼650 mL) pulmonary edema around the staple line during EVLP.

Background: The real-world safety of robotic resections after neoadjuvant chemoimmunotherapy remains poorly defined in patients with non-small cell lung cancer. Due to reported increased operative challenges after neoadjuvant immunotherapy, we aim to describe our early institutional experience and outcomes after robotic resection in this clinical context.
Methods: We performed a retrospective chart review of patients with non-small cell lung cancer who underwent a robotic lobectomy, comparing patients from June 1, 2022, through October 31, 2023, who were treated with neoadjuvant chemoimmunotherapy consistent with the Checkmate-816 protocol and a control group with upfront resection.

Introduction: Spontaneous pneumothorax is a life-threatening thoracic condition that could be either primary spontaneous pneumothorax (PSP) in the absence of an underlying lung disease or secondary spontaneous pneumothorax (SSP) in the presence of an underlying lung disease. In the case of recurrent, contralateral spontaneous pneumothorax or persistent air leak with a chest drain, surgery with bullectomy associated with pleurectomy or pleurodesis is the gold standard management.
Aim: To compare two different techniques for bullectomy, either by using staplers or by hand sewing.

Barotrauma is a medical condition caused by sudden pressure changes in the body causing damage to multiple parts of the body. However, it is an infrequent occurrence when it comes to Colo-rectal perforation, wherein the trauma occurs due to the insufflation of compressed air through the anus. Several factors influence the outcome of a patient with colonic perforation due to barotrauma such as the severity of the injury, hemodynamic status of the patient, the patient's general health and well-being, the time taken for active medical/ surgical intervention since the injury, aggressive intravenous antibiotics administration to prevent sepsis, post-operative complications like surgical site infection, post-op ileus, anastomotic leak, etc.

Background: Hydatid cyst (HC) frequently affects the lungs, making it the second most common site after the liver. This study evaluated the clinical characteristics, surgical procedures, complications, laboratory findings, and factors influencing hospital length of stay (LOS) in patients undergoing surgery for pulmonary hydatid cysts.
Methods: This retrospective observational study included adult patients who underwent surgery for lung HC between 2017 and 2021.
