Aim:
In this study, we aim to analyze the frequency and indications of repeat bronchoscopic procedures performed at our hospital over a five-year period.
Methods:
This retrospective study was conducted at the Department of Pulmonary Diseases, Akdeniz University, and included patients who underwent bronchoscopy between January 1, 2018, and May 31, 2024. Patients who required a repeat bronchoscopy were identified. Inclusion criteria for the repeat bronchoscopy group were non-diagnostic initial bronchoscopy or the need for additional samples for molecular testing in lung cancer patients. Exclusion criteria included patients with incomplete medical records or those who did not provide informed consent for the repeat procedure.
Findings:
A total of 3877 patients underwent bronchoscopy in this time periods. Among these, 69 patients (1.8 %) required a repeat bronchoscopy. The mean age of these patients was 61.3 ± 11.7 years, with 54 (78 %) being male. The most common reason for the repeat procedure was the non-diagnostic outcome of the initial bronchoscopy (n = 53, 77 %), followed by cases where the initial bronchoscopy was diagnostic for lung cancer but insufficient for molecular testing (n = 16, 23 %). Among the 16 patients who underwent molecular testing, sufficient samples for molecular tests were obtained in 12 patients (75 %) following the second bronchoscopy. Molecular tests were negative for driver mutations in 6 patients, while 6 patients tested positive (PD-L1, n = 5; EGFR, n = 1). In 4 patients (25 %), the sample was reported as insufficient for molecular testing. Patients who underwent repeat bronchoscopy had the second procedure an average of 38.5 ± 59.7 days after the initial procedure. No complications developed in patients undergoing repeat bronchoscopy, except for bleeding not requiring intervention related to the bronchoscopy procedure.
Conclusion:
In conclusion, regardless of the reason, repeated bronchoscopy in suitable patients is safe and has a high diagnostic yield.

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...

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
