Abstract: Objective To investigate the sampling errors of two different ways of percutaneous liver biopsies. Methods The liver biopsy in 3059 patients were performed by Menghini needle and in 263 patients by automatic Tru-cut needle. Results The average length of samples by Menghini needle were 2.06±0.62cm,longer than by automatic Tru-cut(1.29±0.50cm,t=17.089,P=0.000);In 221 fragmented tissue samples obtained by Menghini,the liver cirrhosis were confirmed in 184 patients(83.26%);In other 37 patients with fragmented samples without pathological diagnosis at first needle,the second needle by automatic Tru-cut showed liver cirrhosis in 35 patients(94.6%). Conclusion The samples obtained by Menghini are longer than that by automatic Tru-cut. Nearly all the samples with fragmented tissues by suction needle in patients with hepatitis B are diagnosed as liver cirrhosis.
