Safety and efficacy of sonographic-guided random real-time core needle biopsy of the liver

摘要: Purpose. To determine the safety and efficacy of real-time, sonographic-guided, random percutaneous needle biopsy liver in a tertiary medical center. Method. From an IRB-approved database, all patients who had performed over 24-month period were selected. In 350 patients, 539 biopsies under real-time sonographic visualization. The following recorded from electronic record: patient demographics, indication for procedure; radiologist's name; type gauge number passes; use amount IV sedation or anesthesia; adequacy specimen; complications procedure. Result. Of biopsies, 378 (70%) procedures on transplant recipients. Of nontransplant 81/161 (50%) concurrently underwent focal mass. An 18-gauge automated core was used 536/539 (99%). Median passes per procedure 1 (mean, 1.7; range, 1–6). Sedation using midazolam fentanyl 483/539 (90%). There only 8 inadequate specimens (1.5%, [2.3, upper 95% confidence limit, fully described Statistical Analysis]). Complications identified 11/539 (2.0%, [2.6, limit]): 5 with severe postprocedural pain, 3 symptomatic hemorrhage, 2 infection, rash. no sedation-related deaths related to procedure. Conclusion. Real-time, core-needle is safe highly effective procedure. © 2009 Wiley Periodicals, Inc. J Clin Ultrasound
