Abstract
BACKGROUND: This study aims to encourage the use of percutaneous transthoracic biopsies by thoracic surgeons as a diagnostic method. METHODS: This retrospective study was conducted between January 1, 2015, and January 31, 2024, with 793 patients (632 males, 160 females; mean age: 65±12 years; range, 11 to 93 years) who underwent lung tru-cut biopsy under computed tomography guidance. Patients whose radiologic and pathology records were accessible via the Hospital Information System and the Picture Archiving and Communication System were included. RESULTS: A total of 973 tru-cut biopsy procedures were performed. There was no statistically significant difference in age distribution between sexes (p=0.15). Most biopsies were performed on the upper lobes, predominantly the right upper lobe (33.2%). The supine position was the most commonly used during the procedure (49.4%). The mean lesion diameter and distance from the chest wall were 49±17 mm and 51±16 mm, respectively. A definitive diagnosis was obtained on the first attempt in 78.6% of patients, while repeat biopsies were required in 21.4%. Primary lung malignancy was diagnosed in 63% of cases. Postprocedural complications included pneumothorax in 16.1%, intraparenchymal hemorrhage in 0.1%, hemoptysis in 0.1%, and hemothorax in 0.1% of patients. Complications were most frequently observed following biopsies of the left lower lobe (32.4%). Lesions located in the upper lobes were significantly more likely to be malignant (p=0.01). A significant increase in complication rates was observed with greater parenchymal tissue penetration during the procedure (p=0.001). CONCLUSION: Computed tomography-guided percutaneous lung biopsies can be performed more safely by thoracic surgeons due to their procedural experience. Additionally, in the event of complications, thoracic surgeons are more capable of providing prompt and effective intervention, thereby enhancing patient safety. Thoracic surgeons should be actively involved in all diagnostic stages of pulmonary or mediastinal nodules or masses, including procedures such as tru-cut lung biopsy and endobronchial ultrasonography.
