Objective:
To evaluate the usefulness of routine ultrasound assessment of puncture site before performing percutaneous biopsy in diffuse liver disease. Seven hundred fifty-three consecutive patients were studied retrospectively.
Methods:
Serial scanning of the last intercostal spaces allowed us to establish the most suitable access to the thicker liver parenchyma (assessing the most favorable angulation of the needle too), avoiding the puncture of adjacent organs; no more than 1 min was necessary for such a determination.
Results:
In 99.4% of patients, a definitive or indicative pathological diagnosis of chronic liver disease was obtained. Only one hemorrhagic complication (0.13%) occurred, requiring no surgical treatment or blood transfusion. Three cases of vasovagal reaction occurred (0.40%): two of these recovered spontaneously, while the other one needed i.v. administration of atropine. Mortality was 0 in our series.
Conclusions:
Routine ultrasound of the puncture site is a quick method of assessment, allowing one to increase the diagnostic yield of percutaneous liver biopsy and to maintain low complication rates for such a procedure.
