The role of ultrasound-guided transthoracic Tru-Cut core biopsy in the diagnosis peripheral thorax lesion

Abstract

BackgroundThe nature of opaque lesions such as effusions, atelectasis, masses, and consolidations can be clarified by sonography. This study investigated the sensitivity and accuracy of ultrasound-guided percutaneous core needle biopsy in different thoracic tumors (lung, pleural, chest wall, and mediastinal).ResultsSixty patients underwent ultrasound-guided percutaneous transthoracic core biopsy of peripheral thoracic masses with a Tru-Cut needle with a big bore. Twenty masses were in the lung, seventeen lesions were in the pleura, ten masses were in the mediastinum, eleven were enlarged palpable lymph nodes, and two masses were in chest wall. The sensitivity, PPV, and accuracy for detection of chest tumors in the chest wall, mediastinum, lung, and pleura were 100% for all, and in LN 88.9, 100, and 90.9%, respectively. The overall diagnostic performance of sonar-guided Tru-Cut needle biopsy in diagnosis was 97.78% sensitivity, 98.18% accuracy, and 100% PPV.ConclusionTru-Cut needle percutaneous transthoracic core biopsy is a convenient and sensitive process in obtaining samples under ultrasound guidance for exact histological diagnosis of thoracic tumors. The diagnostic efficiency is high, and the technique can also be used in outpatients, which is relatively simple.Trial registrationNCT, NCT04741958 Registered 5 February 2021, retrospectively registered,
