Purpose: This study sought to identify the complication, mortality, and readmission rates of patients undergoing either percutaneous (PCLB) or transjugular liver biopsy (TJLB) when propensity matched for demographics and hepatic comorbidities.
Methods: A retrospective review of New York's Statewide Planning and Research Cooperative System ICD9 coded database from the years 2009-2013 was conducted. Patients over the age of 18 undergoing either PCLB or TJLB were included. Patients with hepatic neoplasm or metastasis were excluded. 2:1 PCLB:TJLB propensity match for age, race, payment, coagulopathy, thrombocytopenia/purpura, hypercoagulability, ascites, acute liver failure, chronic hepatitis, cirrhosis, and bone marrow disease was conducted. Univariate analysis compared demographics, complications, readmissions, and mortality.
Results: 1467 patients met inclusion criteria (PCLB = 978, TJLB = 489). Propensity match was successful in that there were no significant differences in demographics or hepatic comorbidities. TJLB had significantly lower rates of hematoma (0.20 % vs 1.20 %, p = 0.049) and higher rates of cardiac complications (0.40 % vs 0.00 %, p = 0.045). Other complication, readmission, and mortality rates did not differ significantly. Logistic regression found no significant predictors of readmission within 7 days or any complication within 5 days.
Conclusion: This retrospective, multi-center database review of adult patients undergoing PCLB or TJLB propensity matched for demographics and hepatic comorbidities found that TJLB patients had a significantly higher rate of cardiac complications while PCLB patients had a significantly higher rate of hematoma. These findings support prior literature suggesting a trend towards safety of TJLB compared to PCLB in patients with hemostatic disorders and/or advanced liver disease.
