Abstract

Background Orthotopic liver transplantation is the definitive treatment modality for patients with end-stage liver disease. Pre–orthotopic liver transplantation renal dysfunction has a significant negative influence on outcomes post–orthotopic liver transplantation. Intraoperative renal replacement therapy is an adjunctive therapy to address the metabolic challenges during orthotopic liver transplantation in patients with a high acuity of illness. The impact of intraoperative renal replacement therapy on post–orthotopic liver transplantation outcomes, however, is unclear. Methods From October of 2012 to April of 2016, 96 adult patients underwent orthotopic liver transplantation for end-stage liver disease. Three groups were identified: (1) Group I: patients with pre–orthotopic liver transplantation renal dysfunction who underwent intraoperative renal replacement therapy, (2) Group II: patients with pre–orthotopic liver transplantation renal dysfunction who did not receive intraoperative renal replacement therapy, and (3) Group III: patients with orthotopic liver transplantation without evidence of pretransplant renal dysfunction. Results At 17.7 months follow-up, there was no difference in survival among the study groups. Physiologic model for end-stage liver disease at the time of orthotopic liver transplantation was significantly higher in both groups with renal dysfunction (I = 43, II = 39) than in Group III (18). Post–orthotopic liver transplantation, 12-month patient survival in Group II was 100%. While the model for end-stage liver disease score at orthotopic liver transplantation was significantly different between Group I and Group III, the 12-month, post–orthotopic liver transplantation patient survival was comparable at 78% vs 88%, respectively. Conclusion Intraoperative renal replacement therapy is a safe adjunctive therapy during liver transplantation of critically ill patients with renal dysfunction. Identifying patients who require intraoperative renal replacement therapy would improve intraoperative and post–liver transplant survival and may facilitate recovery of native kidney function after transplant.
