Percutaneous CT guided true cut lung Biopsy: Efficacy in Histo Morphological Diagnosis and Complications, A Prospective Study

CT guided percutaneous needle biopsy is an indispensable tool with high diagnostic accuracy in the detection of pulmonary malignancy. It plays a vital role in clinching the evidence of malignancy, grading, differentiating between primary and secondary, and planning for treatment. This article tries to establish the relative usefulness of CT guided lung biopsy in diagnosis of pulmonary malignancies that was later confirmed by use of immunohistochemistry. This prospective study was conducted in a private hospital over a period of one year. All the patients with suspected pulmonary mass lesion on chest X-ray and clinical symptoms suggestive of lung cancer were included in the study. CT guided true cut biopsy was done in each case after obtaining informed consent. Patients were observed for post operative complications. HP study as well as IHC study was done to categorise nodules. Results All biopsies taken under CT guidance showed pictures of malignancy on IHC study. Primary adenocarcinoma was most common type encountered. Conclusion CT guided biopsy is a simple and safe technique with high efficacy and less complications in diagnosis and differentiation of lung nodules.
