BackgroundRenal insufficiency adversely affects outcomes after cardiac and vascular surgery. The effect of preoperative renal insufficiency on outcomes after major hepatectomy is unknown.Study DesignAll patients who underwent major hepatectomy (≥3 segments) at 3 institutions from 2000 to 2012 were identified. Resections were performed using low central venous pressure anesthesia. Renal function was analyzed by preoperative serum creatinine (sCr) level. Primary outcomes were major complications (Clavien grade III to V), respiratory failure, renal failure requiring hemodialysis, and 90-day mortality.ResultsOne thousand one hundred and seventy patients had preoperative sCr levels available. Renal function was analyzed using sCr dichotomized at 1.8 mg/dL, 1 SD higher than the mean value (0.97 ± 0.79 mg/dL) for the cohort. Twenty-two patients had sCr ≥1.8 mg/dL. Major complications occurred in 279 patients (23.8%), respiratory failure in 62 (5.3%), and renal failure in 31 (2.6%). Ninety-day mortality rate was 5.4%. On multivariate analysis, patients with sCr ≥1.8 mg/dL remained at significantly increased risk for major complications (hazard ratio = 3.94; 95% CI, 1.48-10.49; p = 0.006), respiratory failure (hazard ratio = 4.43; 95% CI, 1.33-14.80; p = 0.014), and renal failure (hazard ratio = 4.75; 95% CI, 1.19-18.97; p = 0.028). Serum Cr ≥1.8 mg/dL was not independently associated with 90-day mortality on multivariate analysis (p = 0.27).ConclusionsPreoperative serum creatinine ≥1.8 mg/dL identifies patients at significantly increased risk of postoperative major complications, respiratory failure, and renal failure requiring dialysis. Patients are well selected for major hepatectomy, and few patients with substantial renal insufficiency are deemed operative candidates.Copyright © 2014 American College of Surgeons.
