Transjugular liver biopsy in 52 patients with an automated trucut-type needle

A three-year prospective study was conducted to assess the efficacy and safety of transjugular liver biopsy with a Trucut-type needle employing an automated device. Fifty-two consecutive patients (39 women and 13 men), ages 46.3+/-14.6 years, in whom percutaneous liver biopsy was contraindicated wer...

Description
Summary:A three-year prospective study was conducted to assess the efficacy and safety of transjugular liver biopsy with a Trucut-type needle employing an automated device. Fifty-two consecutive patients (39 women and 13 men), ages 46.3+/-14.6 years, in whom percutaneous liver biopsy was contraindicated were included in the study. An 18-gauge transjugular hepatic needle with a 20-mm throw length, a cutting cannula at the distal end, and an automated trigger device on the proximal end was used. All procedures were performed under fluoroscopic control, and the following variables were assessed: (1) number of passes, (2) size and average number of the obtained fragments, (3) number of portal triads, and (4) adequacy of the specimen for histologic diagnosis. The procedure was successful in 49/52 patients, and all samples obtained were satisfactory for histologic analysis even when cirrhosis or bridging fibrosis were present. Mean biopsy specimen length was 1.7+/-0.88 cm; mean number of passes was 2.42+/-1.01, the mean number of biopsy fragments and portal triads per attempt were 2.5+/-1.01 and 6.24+/-3.18, respectively. No major complications were observed. Transjugular hepatic biopsy with this new cutting system is an effective and safe procedure in patients with contraindication for percutaneous liver biopsy.
