Outcomes of Adult Liver Retransplantation: A Canadian National Database Analysis.

ABSTRACT:

Background

Liver retransplantation remains as the only treatment for graft failure. This investigation aims to assess the incidence, post-transplant outcomes, and risk factors in liver retransplantation recipients in Canada.

Materials and methods

The Canadian Organ Replacement Register was used to obtain and analyse data on all adult liver retransplant recipients, matched donors, transplant-specific variables, and post-transplant outcomes from January 2000 to December 2018.

Results

377 (6.5%) patients underwent liver retransplantation. Autoimmune liver disease and hepatitis C virus (HCV) were the most common underlying diagnoses. Graft failure was 7.9% and 12.5%, and overall survival was 77.1% and 65.6% at 1 year and 5 years, respectively. In contrast to recipients receiving their first graft transplant, the retransplantation group had a significantly higher incidence of graft failure (p < 0.001) and lower overall survival (p < 0.001). The graft failure and patient survival rates were comparable between second transplant and repeat retransplant recipients. Furthermore, there were no differences in graft failure and patient survival when stratified according to time to retransplantation. Recipient and donor age (HR = 1.12, p=0.011; HR = 1.09, p=0.008), recipient HCV status (HR = 1.81, p=0.014), and donor cytomegalovirus status (HR = 4.10, p=0.006) were predictors of patient mortality.

Conclusion

This analysis of liver retransplantation demonstrates that this is a safe treatment for early and late graft failure. Furthermore, even in patients requiring more than two grafts, similar outcomes to initial retransplantation can be achieved with careful selection.

Project description:BackgroundLiver retransplant is the only option to save a patient with liver graft failure. However, it is controversial due to its poor survival outcome compared to primary transplantation. Insufficient deceased organ donation in Taiwan leads to high waitlist mortality. Hence, living-donor grafts offer a valuable alternative for retransplantation. This study aims to analyze the single center's outcome in living donor liver retransplantation (re-LDLT) and deceased donor liver retransplantation (re-DDLT) as well as the survival related confounding risk factors.MethodsThis is a single center retrospective study including 32 adults who underwent liver retransplantation (re-LT) from June 2002 to April 2020. The cohort was divided into a re-LDLT and a re-DDLT group and survival outcomes were analyzed. Patient outcomes over different periods, the effect of timing on survival, and multivariate analysis for risk factors were also demonstrated.ResultsOf the 32 retransplantations, the re-LDLT group (n=11) received grafts from younger donors (31.3 vs. 43.75 years, P=0.016), with lower graft weights (688 vs. 1,457.2 g, P<0.001) and shorter cold ischemia time (CIT) (45 vs. 313 min, P<0.001). The 5-year survival was significantly better in the re-LDLT group than in the re-DDLT group (100% vs. 70.8%, P=0.02). This difference was adjusted when only retransplantation after 2010 was analyzed. Further analysis showed that the timing of retransplantation (early vs. late) did not affect patient survival. Multivariate analysis revealed that prolonged warm ischemia time (WIT) and intraoperative blood transfusion were related to poor long-term survival.ConclusionsRetransplantation with living donor graft demonstrated good long-term outcomes with acceptable complications to both recipient and donor. It may serve as a choice in areas lacking deceased donors. The timing of retransplantation did not affect the long-term survival. Further effort should be made to reduce WIT and massive blood transfusion as they contributed to poor survival after retransplantation.

Project description:GoalsWe aimed to assess outcomes of patients with liver cirrhosis who underwent therapeutic or diagnostic endoscopic retrograde cholangiopancreatography (ERCP) to determine whether these patients had different outcomes relative to patients without cirrhosis.BackgroundERCP is an important procedure for treatment of biliary and pancreatic disease. However, ERCP is relatively technically difficult to perform when compared with procedures such as esophagogastroduodenoscopy or colonoscopy. Little is known about how ERCP use affects patients with liver cirrhosis.StudyUsing patient records from the National Inpatient Sample (NIS) database, we identified adult patients who underwent ERCP between 2009 and 2014 using International Classification of Disease, Ninth Revision coding and stratified data into 2 groups: patients with liver cirrhosis and those without liver cirrhosis. We compared baseline characteristics and multiple outcomes between groups and compared outcomes of diagnostic versus therapeutic ERCP in patients with cirrhosis. A multivariate regression model was used to estimate the association of cirrhosis with ERCP outcomes.ResultsA total of 1,038,258 hospitalizations of patients who underwent ERCP between 2009 and 2014 were identified, of which 31,294 had cirrhosis and 994,681 did not have cirrhosis. Of the patients with cirrhosis, 21,835 (69.8%) received therapeutic ERCP and 9459 (30.2%) received diagnostic ERCP. Patients with cirrhosis had more ERCP-associated hemorrhages (2.5% vs. 1.2%; P <0.0001) compared with noncirrhosis patients but had lower incidence of perforations (0.1% vs. 0.2%; P <0.0001) and post-ERCP pancreatitis (8.6% vs. 7%; P <0.0001). Cholecystitis was the same between groups (2.3% vs. 2.3%; P <0.0001). In patients with cirrhosis, those who received therapeutic ERCP had higher post-ERCP pancreatitis (7.9% vs. 5.1%; P <0.0001) and ERCP-associated hemorrhage (2.7% vs. 2.1%; P <0.0001) but lower incidences of perforation and cholecystitis (0.1% vs. 0.3%; P <0.0001) and cholecystitis (1.9 vs. 3.1%; P <0.0001) compared with those who received diagnostic ERCP.ConclusionsUse of therapeutic ERCP in patients with liver cirrhosis may lead to higher risk of complications such as pancreatitis and postprocedure hemorrhage, whereas diagnostic ERCP may increase the risk of pancreatitis and cholecystitis in patients with cirrhosis. Comorbidities in cirrhosis patients may increase the risk of post-ERCP complications and mortality; therefore, use of ERCP in cirrhosis patients should be carefully considered, and further studies on this patient population are needed.
