Background: Image-guided tru-cut lung biopsy is a surgical procedure done to obtain a sample of lung tissue for histological analysis or for other analyses. However, when image-guided facilities are not readily available, a nonimage-guided lung biopsy may be desirable. Methods: This was a prospective case series of all patients seen in the cardiothoracic surgery unit of a teaching hospital for a 2-year period with clinical and radiologic features suspicious of a malignancy or other lung pathologies, and with evidence of advanced disease. The biodata, clinical features, volume of the specimen, the presence or absence of contaminants or complications, and the histological diagnosis were also collected and descriptively studied. Results: Baseline characteristics – Sixteen patients were seen with a mean age of 49.4 ± 13.7 years (28–67 years). There were 11 (68.8%) females in the sample. With regards to presenting symptoms: 14 patients had predominantly cough, 8 had predominantly dyspnea, and 5 had a combination of various other symptoms. Seven patients (43.8%) had pleural effusion which was drained before the biopsy. Biopsy results – The mean volume of the samples obtained was 1.72 ± 3.8 cm3 (0.02–15.00 cm3). The biopsy sample was contaminated by skeletal muscles in two patients (12.5%). Eleven (68.8%) samples were malignant whereas five (31.2%) were nonmalignant pathologies. There were no major complications such as subcutaneous emphysema or pneumothorax or hemothorax recorded after the procedure in any of the patients. Conclusion: It is possible to do a nonimage-guided tru-cut lung biopsy and yet achieved some level of safety, minimal or no complication, and less cost, even in advanced disease with pleural effusion.
