BACKGROUND: Adequate tissue sampling is fundamental for establishing a definitive diagnosis, assessing prognosis and tailoring therapy. Each of the methods for obtaining tissue (e.g., endoscopic, image guidance and surgical biopsies) results in a different diagnostic yield and complication rate profile.
OBJECTIVES: Present feasibility, and assess safety and efficacy of freehand transthoracic ultrasound-guided core-needle biopsies (USGNB) of thoracic lesions performed by pulmonologist.
METHODS: A retrospective analysis study of ultrasound-guided core-needle biopsies of thoracic lesions performed at the Pulmonary Institute of Rabin Medical Center was conducted from September 2020 to October 2021. All core-needle biopsies were performed under local anesthesia with guidance of Mindray TE7 2019 US system. Procedural variables including complications and pathological diagnostic yield were the primary end point. IRB 0671-21-RMC.
RESULTS: In total 91 biopsy procedures were analyzed in38 females and 53 males, average age 71.1 years. Twenty-three (25.3%) cases were lung lesions, 7 (7.7%) - mediastinal, 13 (14.3%) - chest wall, 27 (29.7%) - pleural, and 21 (23.1%) supraclavicular lesions. Average lesion size was 51.6 mm, the largest in the mediastinum and the smallest in supraclavicular locations (97.7mm and 28.0 mm, respectively). Overall pathological diagnostic yield was 90%, highest success in chest wall (100%) and lowest in mediastinal biopsies (71.4%). We had only one complication -hemothorax resolved by chest tube drainage- accounting for only 1.1% complication rate.
CONCLUSION: Safety and efficacy were demonstrated in freehand US-guided core-needle biopsy of thoracic lesions performed by pulmonologists. We suggest thoracic ultrasound and USG-CNB be part of training and clinical practice in interventional pulmonology.
