AIM To determine the impact of transjugular intrahepatic porto-systemic shunt(TIPS) on post liver transplantation(LT) *** Utilizing the United Network for Organ Sharing(UNOS) database, we compared patients who underwent LT from 2002 to 2013 who had underwent TIPS to those without TIPS for the management of ascites while on the LT waitlist. The impact of TIPS on 30-d mortality, length of stay(LOS), and need for re-LT were studied. For evaluation of mean differences between baseline characteristics for patients with and without TIPS, we used unpaired t-tests for continuous measures and χ~2 tests for categorical measures. We estimated the impact of TIPS on each of the outcome measures. Multivariate analyses were conducted on the study population to explore the effect of TIPS on 30-d mortality post-LT, need for re-LT and LOS. All covariates were included in logistic regression *** We included adult patients(age ≥ 18 years) who underwent LT from May 2002 to September 2013. Only those undergoing TIPS after listing and before liver transplant were included in the TIPS group. We excluded patients with variceal bleeding within two weeks of listing for LT and those listed for acute liver failure or hepatocellular carcinoma. Of 114770 LT in the UNOS database, 32783(28.5%) met inclusion criteria. Of these 1366(4.2%) had TIPS between the time of listing and LT. We found that TIPS increased the days on waitlist(408 ± 553 d) as compared to those without TIPS(183 ± 330 d), P < 0.001. Multivariate analysis showed that TIPS had no effect on 30-d post LT mortality(OR = 1.26; 95%CI: 0.91-1.76) and re-LT(OR = 0.61; 95%CI: 0.36-1.05). Pre-transplant hepatic encephalopathy added 3.46 d(95%CI: 2.37-4.55, P < 0.001), followed by 2.16 d(95%CI: 0.92-3.38, P = 0.001) by TIPS to LOS. CONCLUSION TIPS did increase time on waitlist for LT. More importantly, TIPS was not associated with 30-d mortality and re-LT, but it did lengthen hospital LOS after transplantation.

AIM To examine the effect of center size on survival differences between simultaneous liver kidney transplantation(SLKT) and liver transplantation alone(LTA) in SLKT-listed *** The United Network of Organ Sharing database was queried for patients ≥ 18 years of age listed for SLKT between February 2002 and December 2015. Posttransplant survival was evaluated using stratified Cox regression with interaction between transplant type(LTA vs SLKT) and center *** During the study period, 393 of 4580 patients(9%) listed for SLKT underwent a LTA. Overall mortality was higher among LTA recipients(180/393, 46%) than SLKT recipients(1107/4187, 26%). The Cox model predicted a significant survival disadvantage for patients receiving LTA vs SLKT [hazard ratio, hazard ratio(HR) = 2.85; 95%CI: 2.21, 3.66; P < 0.001] in centers performing 30 SLKT over the study period. This disadvantage was modestly attenuated as center SLKT volume increased, with a 3% reduction(HR = 0.97; 95%CI: 0.95, 0.99; P = 0.010) for every 10 SLKs *** In conclusion, LTA is associated with increased mortality among patients listed for SLKT. This difference is modestly attenuated at more experienced centers and may explain inconsistencies between smaller-center and larger registry-wide studies comparing SLKT and LTA outcomes.
