Age as a Risk Factor in the Occurrence of Complications during or after Bronchoscopic Lung Biopsy.

Bronchoscopic lung biopsy (BLB) is a widely used procedure. As the world's population is ageing, more BLBs are performed for older people with comorbidities. The aim of the study was to investigate if an older age is a risk factor for BLB related complications. A prospective study at the Centre of Pulmonology and Allergology of Vilnius University Hospital Santaros klinikos was conducted. Seven hundred and eighty-six patients (male 60.6%), mean age 57 ± 16, who underwent BLB, were included. The complications that occurred due to BLB were evaluated. Bleeding and pneumothorax were classified into I° or II° grades depending on their severity. Potential determinants, which may increase the risk of complications, emphasizing on age, were analyzed. Fifty-seven (7.2%) BLB-related complications occurred. There were 27 (3.4%) pneumothoraxes, and 19 (70%) of them required thoracic drainage. Thirty (3.8%) bleeding complications occurred, and four (16%) of them were severe. Higher rates of bleeding were found in the age group ≥65 years, Older age is related to a higher incidence of mild bleeding during BLB. However, the risk of life-threatening complications is low despite the age, and older age should not be considered as a contraindication for the procedure if needed.
