P1-054: Percutaneous needle biopsy for peripheral lung lesions smaller than 2cm performed under fluoroscopic CT guidance

(1) Background: The aim of this study was to conduct a prospective analysis on the diagnostic accuracy of transthoracic ultrasound-guided percutaneous needle biopsy (TUS-PNB) for the histological assessment of peripheral lung lesions and to assess the performance of transthoracic ultrasound (TUS) examination vs. chest CT (gold standard) in the differentiation between malignant and benign peripheral lung lesions. (2) Methods: A total of 961 consecutive patients with subpleural pulmonary lesions were enrolled. All the patients received a CT scan with contrast; 762 patients underwent TUS-PTNB for suspicion of malignancy, and the remaining 199 enrolled patients underwent only TUS examination as a part of routine follow-up for known non-malignant subpleural consolidations. (3) Results: Among the 762 TUS-guided biopsies, there were 627 (82.28%) malignant lesions, 82 (10.76%) benign lesions, and 53 (6.96%) indeterminate lesions. The overall diagnostic accuracy was 93.04%. The rates of pneumothorax not requiring chest-tube insertion and self-limited hemoptysis were 0.79 and 0.26%, respectively. Patients were divided into two groups based on the benign or malignant nature of the subpleural consolidations. On TUS, both malignant and benign lesions showed mostly irregular margins and a hypoechoic pattern, but no differences were assessed in terms of sonographic margins and pattern between the two groups. There was poor agreement between TUS and chest CT in assessing air bronchograms and necrotic areas. The only finding in the detection of which TUS showed superiority compared to chest-CT was pleural effusion. (4) Conclusions: TUS-PNB was confirmed to be an effective and safe diagnostic method for peripheral pulmonary consolidation, but their sonographic pattern did not allow to rule out a malignant nature. A pre-operative evaluation on CT images, combined with the possibility of performing additional immunohistochemical and cytological investigations and the experience of the medical staff, may improve the diagnostic yield of TUS-guided biopsies.

Percutaneous Transthoracic Needle Biopsy

Background: Computed tomography (CT) guided percutaneous transthoracic needle biopsy of lung is a routine procedure in patients with suspected malignant lung lesions which are either peripheral or not amenable to biopsy on fibreoptic bronchoscopy.Methods: This prospective study was conducted to obtain complication rates based on patient and physician experience after CT guided lung biopsy of central and peripheral lung lesions.Results: In our study 96 patients were included with 78 patients with peripheral and 18 patients having central lung lesions. The reported post procedural complication rates of CT guided lung biopsy were pulmonary haemorrhage 33.3 %, pneumothorax 21.9%, haemoptysis 15.6%, cough 6.3%, haemothorax 3.1% and fever 3.1%. Two patients required inter costal tube drainage. There was no reported mortality of CT guided lung biopsy in our centre.Conclusions: Pulmonary haemorrhage and pneumothorax are the most common complications of percutaneous transthoracic needle biopsy of the lung, the former one is common with central and the latter one with peripheral lung lesions.
