Yield of ultrasound-guided biopsies of focal lesions in an Internal Medicine Department
Background
Ultrasound-guided biopsy (UGB) is a diagnostic procedure that is usually performed by radiologists; however, its use by internists has been poorly studied. This study evaluated the diagnostic yield, accuracy, and safety of UGB for focal lesions with a high suspicion of malignancy in an Internal Medicine Department.
Methods
We retrospectively analyzed 255 UGB in 248 patients between 2021 and 2024. Solid organ biopsies were performed to evaluate diagnostic yield, complications, and factors associated with success.
Results
The overall diagnostic yield was 84% with an accuracy of 83% for malignancy and 89% for benignity. The biopsies predominantly comprised of hepatic, pulmonary, and lymph node specimens. Major complications occurred infrequently (3%). Factors such as sample size and accumulated experience improved the results.
Conclusions
UGBs performed by internists for focal lesions suspected of malignancy are safe and effective. Its implementation can reduce diagnostic time and improve patient care.
