OBJECTIVE: To evaluate the safety, the quality and adequacy of specimens obtained and the cost benefits associated with performing liver biopsy out of hospital, on a short-stay basis, using radiological guidance. DESIGN AND SETTING: A prospective study undertaken over a three-year period, from March 1998 to March 2001, in a private radiology practice. PATIENTS AND PROCEDURES: 251 patients (159 men) with stable liver disease participated. Coagulation studies were performed within a two-week period before biopsy, which was carried out under the guidance of ultrasound (143 patients) or computed tomography (108 patients). A disposable, spring-loaded gun with an 18-gauge biopsy needle was used in each case. A repeat ultrasound or CT scan was performed after the procedure to monitor for complications such as haemorrhage. MAIN OUTCOME MEASURES: Complications of liver biopsy; adequacy of specimens for histological examination; cost of out-of-hospital procedures compared with liver biopsies performed in the hospital setting. RESULTS: Two hundred and twenty nine patients (91.2%) were discharged 60 minutes after the biopsy. The only post-biopsy complication was pain, either at the biopsy site or in the right shoulder. Pain was severe in three patients and, for one of these patients, a subcapsular hepatic haematoma was found on ultrasound eight days after the biopsy. Sufficient material for histopathological examination was obtained from all patients. The cost of out-of-hospital biopsies was substantially less than the cost of hospital-based, day-stay procedures. CONCLUSIONS: Short-stay, out-of-hospital, radiologically guided liver biopsy is safe for patients who have stable chronic liver disease and acceptable coagulation profiles.
