Peri-operative challenges and long-term outcomes in liver transplantation for polycystic liver disease

Abstract

Background The purpose of this study was to determine peri-operative mortality and long-term outcomes in patients undergoing liver transplantation in the US using the United Network for Organ Sharing (UNOS) database. Methods This study is a retrospective review of liver transplantations (LT) recorded in the UNOS database performed between 1988 and 2010. In total, 107 411 LT were performed in the US, 357 (0.3%) were for adult polycystic liver disease (PLD). A random group of 9416 adult patients transplanted for other diagnoses was created for comparison (10% of the adult non-PLD database). Results Two hundred and seventy-one patients in the adult PLD group were females (75.9%), the mean age was 52.3 ± 8.2 [standard deviation (SD)] years. The median length of transplantation hospital stay was 11 days (interquartile range 8-21). Patients from the PLD group versus the comparison group (9416 patients) consisted of more females, lower Model for End-Stage Liver Disease (MELD) scores (17 versus 21 points), more multi-organ transplants (41% versus 4 %), chronic renal failure (creatinine 2.7 versus 1.5) and fewer patients with chronic hepatitis C (1.4% versus 32%). Peri-operative mortality (≤30 days) was 9% in the PLD versus 6% in the comparison group; however, at 1 year PLD survival was similar (85% versus 85%) to other diagnoses and better at 3 (81% versus 77%) and 5 years (77% versus 71%, overall Log Rank P = 0.006). A similar PLD survival advantage was observed in isolated initial transplants (P = 0.019). Conclusion In spite of early technical challenges and mortality, transplantation should be considered an option for selected patients with PLD as excellent long-term outcomes can be achieved. © 2012 International Hepato-Pancreato-Biliary Association.
