Analysis of the complications of liver biopsies using three different methods: report of 1557 cases / 中华肝脏病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To compare the complication rates induced by three liver biopsy methods.</p><p><b>METHODS</b>One thousand five hundred fifty-seven liver biopsies were performed from 1995 to 2006 by the senior author of the present article. The patients were grouped into a non-ultrasound-guided biopsy group (783 cases), a partially ultrasound-guided group (485 cases) and an ultrasound-guided group (289 cases). The observed complications such as death, hemorrhage, pneumothorax, pain, choleperitoneum and vasovagal syncope were compared between these three groups.</p><p><b>RESULTS</b>Only 1 patient in the non-ultrasound-guided group died. Seven patients (45%), 4 in non-ultrasound-guided group, 2 in partially ultrasound-guided group and 1 in ultrasound-guided group, had hemorrhage complications. The hemorrhage complication rates between partially ultrasound-guided group and ultrasound-guided group had no significant differences and both were lower than those of the non-ultrasound-guided group. Thirty-five patients, 23 in non-ultrasound-guided group and 12 in partially ultrasound-guided group, suffered from pneumothorax; but the rates between the two groups were not significantly different. Forty-eight patients (45%), 28 in non-ultrasound-guided group, 17 in partially ultrasound-guided group and 3 in ultrasound-guided group, had severe pain and the rate in the ultrasound-guided group was significantly lower than those of the other two groups.</p><p><b>CONCLUSION</b>Liver biopsy performed under ultrasound guidance is the safest and most reliable way to do the procedure. It should be recommended in clinical practices.</p>
