Abstract
Aims: The aim of this study was to compare the diagnostic rates, complications and histopathologic diagnoses of aspiration biopsy and tru-cut biopsy procedures in liver parenchyma and to reveal the differences between the technical methods. Methods: Patients who underwent liver parenchymal biopsy in our hospital were identified. While tru-cut biopsy needle was used in the radiology department, aspiration biopsy needle was used in the gastroenterology department. Patients who underwent parenchymal biopsy were included in the study, while lesion biopsies were excluded. Indications for biopsy, presence of hepatitis, type of biopsy needle, number of times, size of biopsy material, pathologic diagnosis and complications after biopsy were evaluated. Results: Of the 113 patients who underwent liver biopsy, 74 were male (mean age 40.38.±17.37 years) and 39 were female (mean age 45.49±15.85 years). Among the patients who underwent liver biopsy, tru-cut biopsy needle was used in 46 patients, while aspiration biopsy needle was used in 67 patients. The biopsy size and number of pieces were statistically significantly higher in aspiration biopsy compared to tru-cut biopsy. There was no difference between the two biopsies in terms of diagnosis rate, complication development, fibrosis staging and score. Conclusion: Percutaneous aspiration and tru-cut biopsies are reliable diagnostic methods with high diagnostic rates and low complication rates. The fact that biopsy is performed by experienced hands, under US guidance, and the number of biopsies is limited reduces the development of complications.
