Liver biopsy--past, present and future.
Percutaneous liver biopsy is widely used for the diagnosis and management of liver diseases. With the advancement in medical technology, there are now different approaches to performing liver biopsy, using various biopsy needles. This review highlights the differences between these various techniques. It re-examines in detail, the contraindications and complications of liver biopsy. Haemorrhage accounts for about 50% of all major complications and is the main cause of mortality. About 25% of complications are pulmonary in nature. The rest consists mainly of infective complications. Day case liver biopsy has been repeatedly shown to be safe in selected patients, but is underpracticed. Routine practice of image-guided biopsy is advocated, even in the absence of discrete lesion. Medicine is constantly evolving. New indications for liver biopsy, eg of transplanted liver, are to be expected. Conversely, with the advent in other less invasive modalities of investigation, some indications will disappear from the list.
