Abstract

Background: Ultrasound-guided biopsies of abdominal organs are not withoutrisks for the patients; in particular, hemorrhagic complications may occur. Thus, over the last few years, automatic biopsy guns have been developed to facilitate the biopsy process. Methods: The aim of our retrospective study was to examine the quality of specimens and the complication rate of ultrasound-guided biopsies of abdominal organs carried out in our institution using the automatic Autovac biopsy system during a period of 1.5 years. Of the total number of 321 biopsies,290 were performed with the 1.2-mm Autovac needle, and in 31 cases the 0.95-mm needle was used. Among the 321 biopsies there were 211 of the liver parenchyma (66%), 47 of a Liver tumor (14%), 38 of the pancreas (12%), 15 of the kidney parenchyma (5%), and 10 of a retroperitoneal tumor (3%). Results: In 310 of the 321 biopsies it was possible to obtain sufficient diagnostically usable material for the pathologist (96.6%). In the other 11 cases the material obtained did not enable proper histologic diagnosis (3.4%). Two of these 11 biopsies were carried out with the 0.95-mm needle, and the other 9 with the 1.2-mm needle. Twenty-four hours after the biopsy eachpatient underwent routine ultrasound examination to exclude a possible bleeding. In eight cases an afterbleeding occurred (total hemorrhagic rate, 2.5%), four times without clinical consequences. The other four bleeding complications were more serious (1.2% of all taps), and all occurred after liver biopsies in patients with a history of liver complaints and abnormal clotting variables. There were no fatalities among our biopsies (mortality rate, 0%). Conclusion: The automatic Autovac biopsy system is suitable and relativelysafe for obtaining sufficient histopathologic material from intra-abdominal organs.
