摘要
Radiofrequency ablation (RFA) for the treatment of hepatic tumors has been increasingly used across the United States. Whether treatment-related morbidity has remained low with broader adoption is unclear. We conducted this study to describe in-hospital morbidity associated with RFA for hepatic tumors and to identify predictors of adverse events in a nationally representative database. %26lt;br%26gt;Using the 2006-2009 Nationwide Inpatient Sample, we evaluated all patients aged a parts per thousand yen40 years who underwent an elective RFA for primary or metastatic liver tumors (N = 1298). Outcomes included in-hospital procedure-specific and postoperative complications. Multivariable logistic regression analyses were performed to identify patient and facility predictors of complications. %26lt;br%26gt;Most patients underwent a percutaneous (39.9 %) or laparoscopic (22.0 %) procedure for metastatic liver tumors (57.5 %). Procedure-specific complications were frequent (18.2 %), with transfusion requirements (10.7 %), intraoperative bleeding (4.3 %), and hepatic failure (2.8 %) being the most common. Arrhythmias [adjusted odds ratio (AOR) = 1.93 (1.23-3.04)], coagulopathy [AOR = 4.65 (2.95-7.34)], and an open surgical approach [AOR = 2.77 (1.75-4.36)] were associated with an increased likelihood of procedure-specific complications, whereas hospital RFA volume a parts per thousand yen16/year was associated with a reduced likelihood [AOR = 0.59 (0.38-0.91)]. Postoperative complications were also common (12.0 %), with arrhythmias, heart failure, coagulopathy, and open surgical approach acting as significant predictors. %26lt;br%26gt;In-hospital morbidity is common after RFA for hepatic tumors. While several patient factors are associated with more frequent procedure-specific complications, treatment at hospitals with an annual volume a parts per thousand yen16 cases/year was associated with a 41 % reduction in the odds of procedure-specific complications.
