Transjugular liver biopsy

Abstract

Biopsy of the liver is considered the ‘gold standard’ and is often necessary for histopathological characterization of hepatic disease processes.The techniques to obtain liver specimen are percutaneous liver biopsy, transjugular liver biopsy and mini-laparoscopic liver biopsy. Percutaneous route is the preferred method for its simplicity, ease and safety. Transjugular biopsy of the liver has become an accepted alternative method of obtaining hepatic tissue in patients with an established contraindication to percutaneous liver biopsy viz. coagulopathy, ascites, extreme obesity, small shrunken liver etc.A total of 67 transjugular liver biopsies were performed between January 2004 and February 2012 in a tertiary care hospital. The procedure was performed on in patient basis after thorough pre procedure work up with jugular puncture under ultrasonography guidance and fluoroscopy guided liver biopsy using LABS 100 liver access and biopsy set.The commonest indication for liver biopsy was work up for indeterminate chronic liver disease and the most common contraindications for percutaneous biopsy that led to biopsy by transjugular route were coagulopathy and ascites. Technical success of the procedure was achieved in 96% cases and no major complications were encountered in this group.Transjugular liver biopsy is a valuable tool for clinical decision making in a specific sub set of patients in whom percutaneous biopsy is contraindicated. Transjugular approach with jugular access under real time USG guidance and liver biopsy using automated core biopsy needle is safe, well tolerated, effective and provides adequate tissue for histological assessment.
