Background: Postoperative air leaks and pleural residual spaces are often encountered during partial lung resections and may adversely affect the immediate outcome prolonging the hospital stay. At present the only treatment consists of maintenance of the chest drainage under suction until resolution of the leaks.
Methods: From January 1995 to December 1997 the authors have operated on and subsequently treated 12 patients presenting prolonged air leaks with residual pleural spaces after lobectomies for lung cancer. The patients underwent respectively: left or right lower lobectomies (n=7), left upper lobectomies (n=3), right upper lobectomies (n=2). In this study the air leak was considered prolonged if it continued and delayed the discharge after surgery beyond the postoperative day 8. The pneumoperitoneum was carried out under local anesthesia. The air was insufflated through a needle inserted just above the umbilical scar as for laparoscopic surgery access up to an amount of about 1200 cc-1300 cc.
Results: We have obtained in all cases and without complications an immediate reduction in the air leaks and a complete resolution of the residual pleural spaces. Chest drainages were removed from 3 to 4 days after the procedure.
Conclusions: The good results achieved suggest that this procedure might be considered for selected cases, being a minor procedure, performed under local anesthesia and with minimum discomfort for the patient.

Even though the COVID-19 pandemic now belongs to the long history of infectious diseases that have struck humanity, pathogenic biological agents continue to pose a recurring threat in private places, but also and mainly in places where the public congregates. In our recent research published in this journal in 2022 and 2023, we considered the illustrative example of a commuter train coach in which a symptomatic or asymptomatic passenger, assumed to be infected with a respiratory disease, sits among other travellers. The passenger emits liquid particles containing, for example, COVID-19 virions or any other pathogen.

Background: Impairment of the visceral pleura following thoracic surgery often leads to air leaks and intrathoracic adhesions. For preventing such complications, mesothelial cell proliferation at the pleural defects can be effective. To develop new materials for pleural defects restoration, we constructed a hybrid artificial pleural tissue (H-APLT) combining polyglycolic acid (PGA) nanofiber sheets with a three-dimensional culture of mesothelial cells and fibroblasts and evaluated its therapeutic efficacy in a rat pleural defect model.

The amount of methane released to the atmosphere from the Nord Stream subsea pipeline leaks remains uncertain, as reflected in a wide range of estimates. A lack of information regarding the temporal variation in atmospheric emissions has made it challenging to reconcile pipeline volumetric (bottom-up) estimates with measurement-based (top-down) estimates. Here we simulate pipeline rupture emission rates and integrate these with methane dissolution and sea-surface outgassing estimates to model the evolution of atmospheric emissions from the leaks.

The plane running between two adjacent pulmonary segments consists of a very thin layer of connective tissue through which the pulmonary vein also runs. To perform an anatomically correct segmentectomy, this segmental plane needs to be divided. Before the operation, the locations of vessels and bronchi are confirmed by three-dimensional computed tomography.

Background: Bronchopleural fistula (BPF) is a rare and often difficult postoperative complication to manage. This case series describes a bronchoscopic technique using a bone plug for closure of BPFs.
Methods: Six patients at Henry Ford Hospital from 2014 to 2021, who had a postoperative BPF after lung resection with curative intent for non-small cell lung cancer, underwent bronchoscopic placement of a customized bone plug.
