Post-hepatectomy hyperbilirubinemia: The point of no return

- Post-hepatectomy hyperbilirubinemia is associated with liver insufficiency and failure.
- The aim of this study was to identify the peak postoperative tbili beyond which survival is improbable.
- A peak postoperative tbili ≥ 18 mg/dL is associated with an 86.6% risk of 90-day mortality.
- There are no survivors for tbili ≥ 30 mg/dL.
- Future studies may determine utility of tbili ≥ 18 as an indication hepatic replacement therapy.

BackgroundPost-hepatectomy hyperbilirubinemia is associated with liver insufficiency and failure. The highest survivable peak total bilirubin (ptbili) is not defined. This study aimed to identify the postop ptbili beyond which survival is improbable or impossible.MethodsAn institutional database of major hepatectomies (≥3 segments, no biliary resections), 2000-2012 was reviewed. Data were analyzed to find ptbili in the first 45 postop days. Factors associated with 90-day mortality (90 DM) and those predictive of ptbili were determined.Results603 pts were analyzed with 90DM of 4.5%. 90 DM for a ptbili ≥ 18 (n = 15) was 86.6%, but only 2.5% for a ptbili < 18. All 6 pts with a ptbili ≥ 30 died. On multivariate analysis, postop ptbili ≥ 18 (HR34.95, CI 3.8-324; p = 0.002) and cirrhosis (HR6.4, CI 1.2-33.2; p = 0.027) were associated with 90DM. Factors associated with a ptbili ≥ 18 were age >65 (HR14.24, CI 2.9-70.5; p = 0.001), preop chemotherapy (HR4.77, CI 1.3-18.2; p = 0.02) and postop FFP (HR12.5, CI 2.6-56.2; p = 0.001).ConclusionPostop ptbili ≥ 18 after major hepatectomy has an 86.6% risk of 90DM; there are no survivors for tbili ≥ 30. These values may guide postop counseling for prognosis. Future studies may evaluate tbili ≥ 18 as an indication for hepatic replacement therapy.
