| Purpose: To assess the safety and usefulness of ultrasonography-guided transthoracic
cutting biopsy for lung lesions.
Materials and Methods: Eighty-eight patients (66 men, 22 women, mean age 59
years) with lung lesions underwent an ultrasonography(USG)-guided transthoracic
cutting biopsy. The final diagnosis was based on the findings of surgery and clinical
and radiological follow-ups. The histopathologic results and diagnostic accuracy of
cutting biopsy were determined. Also, the complication rate was statistically evaluated
according to the mass size, number of biopsies, and the presence or absence of
pleural effusion.
Results: Biopsy specimens were successfully obtained in all patients. 79 of 88
lesions (89.8%) were established by histopathology. The final diagnosis was malignant
in 58 and benign in 28. The remaining 2 patients were lost to follow-up.
Diagnostic sensitivity for malignant lesions was 89.6% (52/58) and that for benign
lesions was 96.4% (27/28). Procedure-related complications occurred in 9 patients
(10.2%) including pneumothorax (n = 2) and hemoptysis (n = 7). And there was no
significant difference according to mass size, number of biopsies, or presence of
pleural effusion.
Conclusions: USG-guided transthoracic cutting biopsy is a useful and safe
method for technically-feasible lung lesions.
