Background:
We hypothesize that previous COVID-19 infection could be associated with postoperative complications (POCs) and outcomes of thoracic surgery for lung cancer. It is unknown whether the respiratory damage caused by COVID-19 infection is permanent. In addition, there is a lack of studies investigating POCs and prior COVID-19 infection in thoracic surgery.
Methods:
A retrospective study was performed on patients who underwent resections for lung cancer between May 2020 and July 2022. Variables relevant to the Society of Thoracic Surgeons database were collected, as well as COVID-19 status. The primary outcome was postoperative complications.
Results:
A total of 361 patients underwent a resection for lung cancer. Patients with a prior COVID-19 infection (n = 21) had significantly more POCs than patients without a history of COVID-19 infection (n = 340, P < .05). Pneumothorax and infections requiring intravenous antibiotics were significantly enriched in patients with a prior COVID-19 infection. COVID-19 infection was independently associated with increased POCs at multivariable analysis (adjust odds ratio, 4.36; 95% CI, 1.48-12.8). Matched case-control analysis also reviewed similar findings, where COVID-19 infection was the only significant variable as a risk factor for POCs (P < .05).
Conclusions:
After a COVID-19 infection, patients undergoing lung cancer resections were at an increased risk of POCs. This suggests that a previous COVID-19 infection should be considered as a potential risk factor for complications after lung cancer resections.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
