“…They also showed higher parenchymal haemorrhage among all the complications as in our study. 11 Similar finding was also seen in the study done by Thapa et al 8 However, Jumpei and Yuan et al found pneumothorax as the most common complication. 9,10 Wang et al also found significant correlation of parenchymal haemorrhage with diameter of lesion and length of needle within the lung parenchyma, which was not seen in our study.…”

Background: Early diagnosis of lung cancer can reduce its mortality and morbidity. Minimally invasive image guided percutaneous core needle biopsy can obtain tissue sample for diagnosis and staging of lung cancer, which is crucial for correct management of lung lesions. Common complications of lung biopsy include pneumothorax, parenchymal haemorrhage and haemoptysis. The study was aimed to determine diagnostic yield and complications of the percutaneous computed tomography (CT) guided core needle biopsy of lung lesion in tertiary hospital.Methods: Hospital based prospective study was performed in 40 patients in Tribhuvan University Teaching Hospital. CT guided biopsy of lung lesions was performed with 18-gauge semi-automated biopsy instrument. The complications following the biopsy were recorded and correlated with different factors using chi-square test. Histopathology report were obtained to measure the diagnostic yield.Results: Among 40 patients who underwent guided lung biopsy, histopathology showed definitive diagnosis in 37 patients; 31 malignant and 6 benign lesions. Parenchymal haemorrhage, pneumothorax and haemoptysis were seen in 13, 8 and 5 respectively; however, none required active intervention. Emphysema in traversing lung and numbers of pleural punctures used were predictive factors of complication (p value <0.05).Conclusions: The study showed percutaneous image guided core needle biopsy has high diagnostic yield with fewer complication rates and is thus recommended for routine biopsies of lung lesions.

"Introduction: Pathological confirmation of a newly identified tumor is mandatory to create an adequate treatment plan. Patients may have multiple health comorbidities, making them unsuitable for traditional invasive diagnostic procedures. The percutaneous transthoracic biopsy is a minimally invasive alternative method that can provide tissue samples to identify, diagnose, and classify lung or mediastinal tumors. Materials and methods: Data from patients who underwent fluoroscopic-guided transthoracic needle biopsy (FGTNB) in a tertiary cancer center in the Republic of Moldova from 2019 to 2021 were collected retrospectively. Results: We identified 54 patients with lung and 12 with mediastinal tumors. In the lung tumor group, the median age was 57 years; in the mediastinal tumor group, the median was 27.5 years. Most lung tumors were situated in the superior lobes (79.6%) and were found to be less than 5 cm in diameter (70.4%). Most mediastinal tumors were anteriorly located (66.7%) and were found to be more than 10 cm in diameter (58.3%). The sensitivity of transthoracic percutaneous biopsy was 79.6% in lung tumors and 83.3% in mediastinal tumors. The patients we biopsied were identified with either malignancy, infectious pathology, or pulmonary fibrosis. Transthoracic needle biopsy of the lung showed a low rate of pneumothorax (5.6%) and a low rate of bleeding (3.7%). Mediastinal tumor biopsy had a rate of pneumothorax of 16.7%, significantly higher than lung biopsy. Conclusion: Transthoracic needle biopsy performed under fluoroscopic guidance is a safe and efficient alternative diagnostic procedure for comorbid patients with lung or mediastinal tumors."
