Introduction Liver acceptance patterns vary significantly between transplant centers. Data pertaining to outcomes of livers declined by local and regional centers and allocated nationally remains limited. Project aim The objective was to compare post-liver transplant outcomes between liver allografts transplanted as a result of national and local-regional allocation. Design This was a retrospective evaluation of 109 nationally allocated liver allografts used for transplant by a single center. Outcomes of nationally allocated grafts were compared to standard allocation grafts (N = 505) during the same period. Results Recipients of nationally allocated grafts had lower model for end stage liver disease scores (17 vs 22, P = .001). Nationally allocated grafts were more likely to be post-cross clamp offers (29.4% vs 13.4%, P = .001) and have longer cold ischemia times (median hours 7.8 vs 5.5, P = .001). Early allograft dysfunction was common (54.1% vs 52.5%, P = .75) and did not impact hospital length of stay (median 5 vs 6 days, P = .89). There were no differences in biliary complications ( P = .11). There were no differences in patient ( P = .88) or graft survival ( P = .35). In a multivariate model, after accounting for differences in cold ischemia time and posttransplant biliary complications, nationally allocated grafts were not associated with increased risk for graft loss (HR 0.9, 95% CI 0.4-1.8). Abnormal liver biopsy findings (33.0%) followed by donor donation after circulatory death status (22.9%) were the most common reasons for decline by local-regional centers. Conclusion Despite longer cold ischemia times, patient and graft survival outcomes remain excellent and comparable to those seen from standard allocation grafts.

Background and Aims: Identifying international differences in utilization and outcomes of liver transplantation (LT) after donation after circulatory death (DCD) donation provides a unique opportunity for benchmarking and population-level insight. Methods: Adult (≥18 years) LT data between 2008 and 2018 from the UK and US were used to assess mortality and graft failure after DCD LT. We used time-dependent Cox-regression methods to estimate hazard ratios (HR) for risk-adjusted short-term (0–90 days) and longer-term (90 days–5 years) outcomes. Results: One-thousand five-hundred-and-sixty LT receipts from the UK and 3426 from the US were included. Over the study period, the use of DCD livers increased from 15.7% to 23.9% in the UK compared to 5.1% to 7.6% in the US. In the UK, DCD donors were older (UK:51 vs. US:33 years) with longer cold ischaemia time (UK: 437 vs. US: 333 min). Recipients in the US had higher Model for End-stage Liver Disease (MELD) scores, higher body mass index, higher proportions of ascites, encephalopathy, diabetes and previous abdominal surgeries. No difference in the risk-adjusted short-term mortality or graft failure was observed between the countries. In the longer-term (90 days–5 years), the UK had lower mortality and graft failure (adj.mortality HR:UK: 0.63 (95% CI: 0.49–0.80); graft failure HR: UK: 0.72, 95% CI: 0.58–0.91). The cumulative incidence of retransplantation was higher in the UK (5 years: UK: 11.9% vs. 4.6%; p

Liver transplant remains the definitive therapy for patients with end-stage liver disease. Outcomes have continued to improve, in part owing to interventions used to treat posttransplant complications involving the hepatic arteries, portal vein, hepatic veins or inferior vena cava (IVC), and biliary system. Significant hepatic artery stenosis can be treated with angioplasty or stent placement to prevent thrombosis and biliary ischemic complications. Hepatic arterioportal fistula and hepatic artery pseudoaneurysm are rare complications that can often be treated with endovascular means. Treatment of hepatic artery thrombosis can have mixed results. Portal vein stenosis can be treated with venoplasty or more commonly stent placement. The rarer portal vein thrombosis can also be treated with endovascular techniques. Hepatic venous outflow stenosis of the hepatic veins or IVC is amenable to venoplasty or stent placement. Complications of the bile ducts are the most encountered complication after liver transplant. When not amenable to endoscopic intervention, biliary stricture, bile leak, and ischemic cholangiopathy can be treated with percutaneous transhepatic cholangiography with biliary drainage and other interventions. New techniques have further improved care for these patients. Transsplenic portal vein recanalization has improved transplant candidacy for patients with chronic portal vein thrombosis. Spontaneous splenorenal shunt and splenic artery steal syndrome (nonocclusive hepatic artery hypoperfusion syndrome) remain complicated topics, and the role of endovascular embolization is developing. When patients have recurrence of cirrhosis after transplant, most commonly due to viral hepatitis, transjugular intrahepatic portosystemic shunt (TIPS) may be required to treat symptoms of portal hypertension.

As the number of donation after circulatory death (DCD) liver transplants (LTs) performed in the United States continues to increase annually, there has been interest by policy makers to develop a more robust exception point safety net for patients who develop ischemic cholangiopathy (IC) following DCD LT. As such, there is a need for better understanding of the clinical course and long-term outcomes in patients who develop IC, as well as determining if IC can be classified into distinct categories with distinctly different clinical outcomes.All DCD LT performed at Mayo Clinic Florida, Mayo Clinic Arizona, and Mayo Clinic Rochester from January 1999 to March 2020 were included (N = 770). Outcomes were compared between 4 distinct radiologic patterns of IC: diffuse necrosis, multifocal progressive, confluence dominant, and minor form.In total, 88 (11.4%) patients developed IC, of which 42 (5.5%) were listed for retransplantation of liver (ReLT). Patients with diffuse necrosis and multifocal progressive patterns suffered from frequent hospital admissions for cholangitis in the first year following DCD LT (median 3 and 2), were largely stent dependent (100% and 85.7%), and almost universally required ReLT. Patients with confluence dominant disease were managed with multiple stents and frequently recovered, ultimately becoming stent free without need for ReLT. Patients with the minor form IC did well with limited need for stent placement or repeat procedures and did not require ReLT. Graft survival was different between the 4 distinct IC patterns (P 0.001).The present analysis provides a detailed analysis on the natural history and clinical course of IC. Patients developing IC can be classified into 4 distinct patterns with distinct clinical courses.

In this report, we present a case of successful long-term salvage of a patient with transfusion-related acute lung injury associated with acute respiratory distress syndrome immediately after a liver transplant. The patient was a 29-year-old man with end-stage liver disease due to sclerosing cholangitis who underwent liver transplant. After organ reperfusion, there was evidence of liver congestion, acidosis, coagulopathy, and acute kidney injury. He received 61 units of blood products. Continuous renal replacement therapy was initiated intraoperatively. On arrival to the intensive care unit, the patient was on high-dose pressors, and the patient developed respiratory failure and was immediately placed on veno-arterial extracorporeal membrane oxygenation via open femoral exposure. The patient presented with severe coagulopathy and early allograft dysfunction; therefore, no systemic heparin was administered and no thrombotic events occurred. He required extracorporeal membrane oxygenation support until posttransplant day 4, when resolution of the respiratory and cardiac dysfunction was noted. At 2 years after liver transplant, the patient has normal liver function, normal cognitive function, and stage V chronic kidney disease. We conclude that extracorporeal membrane oxygenation is a valuable therapeutic approach in patients with cardiorespiratory failure after liver transplant.

We report our experience with 3 strategies for treating hilar and extrahepatic cholangiocarcinoma (CCA) including chemoradiotherapy: neoadjuvant chemoradiotherapy (nCRT) and orthotopic liver transplant, surgical resection and adjuvant chemoradiotherapy (aCRT), and definitive chemoradiotherapy (dCRT).We included patients treated from 1998 through 2019. Kaplan-Meier estimates, log-rank testing, and univariate/multivariate Cox models were used to assess outcomes (local progression-free survival, disease-free survival, and overall survival).Sixty-five patients (nCRT, n=20; aCRT, n=16; dCRT, n=29) met inclusion criteria [median (range) age 65 years (27-84 years)]. Median posttreatment follow-up was 19.1 months (0.8-164.8 months) for all patients and 38.6, 24.3, and 9.0 months for the nCRT, aCRT, and dCRT groups, respectively. At 3 and 5 years, overall survival was 78% and 59% for the nCRT group; 47% and 35%, aCRT group; and 11% and 0%, dCRT group. Compared with the dCRT group, the nCRT group (hazard ratio =0.13, 95% CI: 0.05-0.33) and the aCRT group (hazard ratio =0.29, 95% CI: 0.14-0.64) had significantly improved overall survival (P0.001). The 5-year local progression-free survival (50% nCRTOutcomes for patients with extrahepatic CCA were superior for those who underwent nCRT/orthotopic liver transplant or postsurgical aCRT than for patients treated with dCRT. The excellent outcomes after nCRT/orthotopic liver transplant provide additional independent data supporting the validity of this strategy. The poor survival of patients treated with dCRT highlights a need for better therapies when surgery is not possible.

Hispanic patients receive disproportionately fewer living donor kidney transplants (LDKTs) than non-Hispanic Whites (NHWs). The Northwestern Medicine Hispanic Kidney Transplant Program (HKTP), designed to increase Hispanic LDKTs, was evaluated as a nonrandomized, implementation-effectiveness hybrid trial of patients initiating transplant evaluation at two intervention and two similar control sites. Using a mixed method, observational design, we evaluated the fidelity of the HKTP implementation at the two intervention sites. We tested the impact of the HKTP intervention by evaluating the likelihood of receiving LDKT comparing pre-intervention (January 2011-December 2016) and postintervention (January 2017-March 2020), across ethnicity and centers. The HKTP study included 2063 recipients. Intervention Site A exhibited greater implementation fidelity than intervention Site B. For Hispanic recipients at Site A, the likelihood of receiving LDKTs was significantly higher at postintervention compared with pre-intervention (odds ratio [OR] = 3.17 95% confidence interval [1.04, 9.63]), but not at the paired control Site C (OR = 1.02 [0.61, 1.71]). For Hispanic recipients at Site B, the likelihood of receiving an LDKT did not differ between pre- and postintervention (OR = 0.88 [0.40, 1.94]). The LDKT rate was significantly lower for Hispanics at paired control Site D (OR = 0.45 [0.28, 0.90]). The intervention significantly improved LDKT rates for Hispanic patients at the intervention site that implemented the intervention with greater fidelity. Registration: ClinicalTrials.gov registered (retrospectively) on September 7, 2017 (NCT03276390).

Concerns regarding outcomes and early resource utilization are potential deterrents to broader use of kidneys at risk for delayed graft function (DGF). We assessed outcomes specific to kidneys with DGF that required early readmission following transplant. Three groups were identified: 1) recipients with DGF not requiring readmission, 2) recipients with DGF having an isolated readmission, and 3) recipients with DGF requiring ≥2 readmissions. Most recipients either required a single readmission (26.8%, n = 247) or no readmission (56.1%, n = 517); 17.1% (n = 158), had ≥2 readmissions. Recipients requiring ≥2 readmissions were likely to be diabetic (53.8%, p = 0.04) and have longer dialysis vintage (p = 0.01). Duration of DGF was longer with increasing number of readmissions (p < 0.001). There were no differences in patient survival for those with DGF and 0, 1 and ≥2 readmissions (p = 0.13). Graft survival, however, was lower for those with ≥2 readmissions (p < 0.0001). This remained true when accounting for death-censored graft loss (p = 0.0012). Additional subgroup analysis was performed on mate kidneys with and without DGF and mate kidneys, both with DGF, with and without readmissions. For these subgroups, there were no differences in patient or graft survival. As a whole, patients with DGF have excellent outcomes, however, patients with DGF requiring ≥2 readmissions have lower graft survival. A better understanding of recipient variables contributing to multiple readmissions may allow for improvements in the utilization of DGF at-risk kidneys.

In the United States, Hispanic/Latinx patients receive disproportionately fewer living donor kidney transplants (LDKTs) than non-Hispanic White patients. Northwestern Medicine's culturally targeted Hispanic Kidney Transplant Program (HKTP) was found to increase LDKTs in Hispanic patients at 1 of 2 transplant programs with greater implementation fidelity.We conducted a budget impact analysis to evaluate HKTP's impact on program financial profiles from changes in volume of LDKTs and deceased donor kidney transplants (DDKTs) in 2017 to 2019. We estimated HKTP programmatic costs, and kidney transplant (KT) program costs and revenues. We forecasted transplant volumes, HKTP programmatic costs, and KT program costs and revenues for 2022-2024.At both programs, HKTP programmatic costs had1% impact on total KT program costs, and HKTP programmatic costs comprised1% of total KT program revenues in 2017-2019. In particular, the total volume of Hispanic KTs and HKTP LDKTs increased at both sites. Annual KT program revenues of HKTP LDKTs and DDKTs increased by 226.9% at site A and by 1042.9% at site B when comparing 2019-2017. Forecasted HKTP LDKT volume showed an increase of 36.4% (site A) and 33.3% (site B) with a subsequent increase in KT program revenues of 42.3% (site A) and 44.3% (site B) among HKTP LDKTs and DDKTs.HKTP programmatic costs and KT evaluation costs are potentially recoverable by reimbursement of organ acquisition costs and offset by increases in total KT program revenues of LDKTs; transplant programs may find implementation of the HKTP financially manageable.

Statin therapy may reduce the risk of venous thromboembolism (VTE), which may impact solid organ transplant outcomes. We evaluated the incidence of VTE and other complications after liver transplantation stratified by hyperlipidemia status and statin use using a retrospective cohort study approach from a high-volume liver transplant center. We reviewed all primary orthotopic liver transplant (OLT) records from January 2014-December 2019 from our center. Intraoperative deaths were excluded. Recipient and donor clinical and demographic data were collected. We developed risk-adjusted models to assess the effect of statin use on the occurrence of VTE, hepatic artery complications, graft failure, and death, accounting for clinical covariates and competing risks. 672 OLT recipients were included in the analysis. 11.9% (n=80) of this cohort received statin therapy. 47 patients (7.0%) had VTE events. Hepatic artery complications occurred in 40 patients (6.0%). 42 (6.1%) patients experienced graft loss while 9.1% (n=61) of the cohort died during the study interval. 268 (39.9%) OLT recipients had hyperlipidemia, of which 80 (29.8%) were treated with statins. Of those treated with statins, 0% of patients had VTE vs. 7.9% of those not on statins (p=0.01). Hepatic artery complications were identified in 1.2% of the statin group and 6.8% of the non-statin group. Untreated hyperlipidemia was associated with a 2.1-fold higher risk of hepatic artery complications vs no hyperlipidemia status patients (p=0.05). Statins were associated with significantly better risk-adjusted thromboembolic event-free survival (absence of DVT, PE, CVA, MI, HAC, and death) (90% statins vs. 73.9% untreated; HR =0.37, p = 0.01). These data indicate that statin therapy is correlated with a lower rate of VTE and hepatic artery complications after liver transplantation. Prospective studies are warranted.

Kidneys from very young pediatric donors continue to be underutilized. To reduce discard, the Organ Procurement and Transplantation Network (OPTN) policy was recently updated to allow kidneys from donors weighing18 kg to be recovered en bloc.We reviewed our center's experience with kidney transplantation in adult recipients of18 kg pediatric donor kidneys to assess renal function outcomes specific to solitary vs en bloc usage.The majority of18 kg donors were used en bloc (n = 39, 72.2% vs n = 15, 27.8%). Donor weight (kg) was similar between the 2 groups (12.3 ± 3.2 vs 14.1 ± 2.5, P = .05). Recipient weight was lower in the solitary kidney group (P = .01). Both groups had a similar donor-to-recipient body weight ratio (0.24 ± 0.3 vs 0.18 ± 0.3, P = .51). The solitary kidney group had a lower estimated glomerular filtration rate at 1 (56.9 ± 24.3 vs 81.8 ± 24.8, P = .01) and 2 years (72 ± 18.6 vs 93.7 ± 21.6, P = .03). By 2 years, both groups had an average estimated glomerular filtration rate60 mL/min. Kidney allograft growth occurred in both groups, with the largest increase occurring the first month posttransplant (11.9%, 18.6%, P.0001).For pediatric donors weighing18 kg, improvements in renal function continue beyond the first posttransplant year. Risk for hyperfiltration injury appears low and renal mass-recipient mass matching is useful in guiding decision-making for solitary vs en bloc utilization.

Dual kidney transplantation (DKT), utilizing two adult kidneys from the same donor for one recipient, has been used as a way to expand the available donor pool. These kidneys often come from high Kidney Donor Profile Index donors (KDPI 85%). Data comparing outcomes between high KDPI DKT and single kidney transplants (SKT) remain limited. We assessed outcomes of 336 high KDPI kidney transplants performed at our center; 11.0% (n = 37) were DKT. Recipients of DKT were older (P = .02) and donors had a higher KDPI score (median 96% vs. 91%, P .0001). DKT operative time was higher compared to SKT (+1.4 hours, P .0001). There were no differences in delayed graft function (54.1% vs. 51.5%, P = .77) and hospital length of stay (median 4.0 vs. 3.0 days, P = .21) between DKT and SKT. Grade I Clavien-Dindo complications occurred in 8.1% of DKT and 13.7% of SKT (P = .008). There were no grade IVa, IVb, or V complications in either group. DKT had more glomerulosclerosis (P = .04), interstitial fibrosis (P = .02), tubular atrophy (P = .01), and arterial thickening (P = .03) on 1-year protocol biopsies. Estimated glomerular filtration was higher for DKT at 1- (P = .004) and 2-years post-transplant (P = .01). There were no differences in patient (HR 1.3, 95% CI .5-3.3, P = .58) or graft (HR 1.1, 95% CI .5-2.3, P = .83) survival. Good outcomes can be achieved with DKT using high KDPI kidneys with moderate chronic changes. DKT is a good option to help further utilize high KDPI kidneys and minimize discard.

This study aimed to assess the differences between the United States and the United Kingdom in the characteristics and posttransplant survival of patients who received donation after circulatory death (DCD) liver allografts from donors aged60 y.Data were collected from the UK Transplant Registry and the United Network for Organ Sharing databases. Cohorts were dichotomized into donor age subgroups (donor60 y [D60]; donor ≤60 y [D ≤60]). Study period: January 1, 2001, to December 31, 2015.1157 DCD LTs were performed in the United Kingdom versus 3394 in the United States. Only 13.8% of US DCD donors were aged50 y, contrary to 44.3% in the United Kingdom. D60 were 22.6% in the United Kingdom versus 2.4% in the United States. In the United Kingdom, 64.2% of D60 clustered in 2 metropolitan centers. In the United States, there was marked inter-regional variation. A total of 78.3% of the US DCD allografts were used locally. One- and 5-y unadjusted DCD graft survival was higher in the United Kingdom versus the United States (87.3% versus 81.4%, and 78.0% versus 71.3%, respectively; P0.001). One- and 5-y D60 graft survival was higher in the United Kingdom (87.3% versus 68.1%, and 77.9% versus 51.4%, United Kingdom versus United States, respectively; P0.001). In both groups, grafts from donors ≤30 y had the best survival. Survival was similar for donors aged 41 to 50 versus 51 to 60 in both cohorts.Compared with the United Kingdom, older DCD LT utilization remained low in the United States, with worse D60 survival. Nonetheless, present data indicate similar survivals for older donors aged ≤60, supporting an extension to the current US DCD age cutoff.

Outcomes of both donation after cardiac death (DCD) liver and kidney transplants are improving. Experience in simultaneous liver-kidney transplant (SLK) using DCD donors, however, remains limited. In an updated cohort (2010-2018), outcomes of 30 DCD SLK and 131 donation after brain death (DBD) SLK from Mayo Clinic Arizona and Mayo Clinic Minnesota were reviewed. The Model for End-Stage Liver Disease score was lower in the DCD SLK group (23 vs 29, P = .01). Kidney delayed graft function (DGF) rates were similar between the 2 groups (P = .11), although the duration of DGF was longer for DCD SLK recipients (20 vs 4 days, P = .01). Liver allograft (93.3% vs 93.1%, P = .29), kidney allograft (93.3% vs 93.1%, P = .91), and patient (96.7% vs 95.4%, P = .70) 1-year survival rates were similar. At 1 year, there were no differences in the estimated glomerular filtration rate (57.7 ± 18.2 vs 56.3 ± 17.7, P = .75) or progression of fibrosis (ci) on protocol kidney biopsy (P = .67). A higher incidence of biliary complications was observed in the DCD SLK group, with ischemic cholangiopathy being the most common (10.0% vs 0.0%, P = .03). The majority of biliary complications resolved with endoscopic management. With appropriate selection, DCD SLK recipients can have results equivalent to those of DBD SLK recipients.

Objective To evaluate the outcomes and perioperative complication rates following robot- assisted transplant nephrectomy ((RATN). Methods All patients who underwent RATN at our institution were included. No exclusion criteria were applied. Clinical records were retrospectively reviewed and reported. This included preoperative, intraoperative, and postoperative outcomes. Complications were reported utilizing the Clavien-Dindo classification system. Descriptive statistics were reported using frequencies and percentages for categorical variables, means and standard deviation for continuous variables. Results Between July 2014 and April 2018, 15 patients underwent RATN. Most patients had the transplant in the right iliac fossa (13/15). Ten patients underwent a concomitant procedure. The total operative time for the entire cohort was 336 (±102) minutes (including cases who had concomitant procedures) and 259 (±46 minutes) when cases with concomitant procedures were excluded. Mean estimated blood loss was 383 (±444) mL. Postoperatively, 3 patients required blood transfusion. Average hospital stay was 4 (±2.7) days. Most patients had finding consistent with graft rejection on final pathology. There were 5 complications; 3 of which were minor (grade 2 = 2 and grade 3 = 1); one patient had a wound infection requiring dressing (3A) and one patient died due to pulmonary embolism following discharge. Limitations include small series and retrospective nature of the study. Conclusion This case series demonstrate that RATN is technically feasible. With continued experience and larger case series, the robotic approach may provide a minimally invasive alternative to open allograft nephrectomy.

Purpose of review Deceased donation represents the largest supply of organs for transplant in the United States. Organs with suboptimal characteristics related to donor disease or recovery-related issues are increasingly discarded at the time of recovery, prompting late allocation to candidates later in the match sequence. Late allocation contributes to organ injury by prolonging cold ischemia, which may further lead to the risk of organ discard, despite the potential to provide benefit to certain transplant candidates. Recent findings Expedited placement of marginal organs has emerged as a strategy to address the growing problem of organ discard of marginal organs that have been declined late after recovery. In this review, we describe the basis for expedited organ placement, and approaches to facilitating placement of these grafts, drawing examples from kidney and liver donation and transplantation globally. Summary There is significant global variation in practice related to late allocation. Multiple policy mechanisms exist to facilitate expedited placement, including simultaneous offers to multiple centers, predesignation of aggressive centers, and increasing organ procurement organization autonomy in late allocation. Optimizing late allocation of deceased donor organs holds significant promise to increase the number of transplants.

Hepatocellular Carcinoma (HCC) is the most common liver malignancy and third leading cause of cancer death worldwide. For early- and intermediate-stage disease, liver-directed therapies for locoregional control, or down-staging prior to definitive surgical therapy with hepatic resection or liver transplantation, have been studied broadly, and are the mainstays of current treatment guidelines. As HCC incidence has continued to grow, and with more patients presenting with advanced disease, our current treatment modalities do not suffice, and better therapies are needed to improve disease-specific and overall survival. Until recently, sorafenib was the only systemic therapy utilized, and was associated with dismal results. The advent of immuno-oncology has been of significant interest, and has changed the paradigm of therapy for HCC. Lately, combination regimens including atezolizumab plus bevacizumab; durvalumab plus tremelimumab; and pembrolizumab plus Lenvatinib have shown impressive responses of between 25–35%; this is much higher than responses observed with single agents. Complete responses with checkpoint inhibitor therapy have been observed in advanced-stage HCC patients. These dramatic results have naturally led to several questions. Can or should checkpoint inhibitors, or other immunotherapy combinations, be used routinely before resection or transplant? Is there a synergistic effect of immunotherapy with locoregional therapy, and will pre-treatment increase disease-free survival after surgical intervention? Is it immunologically safe to use these therapies prior to transplantation? Much is still to be learned in terms of the dosing, timing, and overall utility of the use of immune checkpoint inhibitors for pre-transplant care and down-staging. More studies will be needed to understand the management of adverse events while maximizing the therapeutic window of these agents. In this review, we look at the current data on therapy with immune checkpoint inhibitors in advanced HCC, with a focus on pre-transplant treatment prior to liver transplant.

BACKGROUND Given the potentially additive risk from using donor livers that are both steatotic and from a donation after circulatory death (DCD) donor, there is a paucity of data on the outcome of DCD liver transplantation (LT) utilizing livers with macrosteatosis. METHODS All DCD LT performed at Mayo Clinic-Florida, Mayo Clinic-Arizona, and Mayo Clinic-Rochester from 1999 to 2019 were included (N = 714). Recipients of DCD LT were divided into 3 groups: those with moderate macrosteatosis (30%-60%), mild macrosteatosis (5%-30%), and no steatosis (

OBJECTIVE To understand whether reduced lengths of stay after kidney transplantation were associated with excess health care utilization in the first 90 days or long-term graft and patient survival outcomes. BACKGROUND Reducing length of stay after kidney transplant has an unknown effect on post-transplant health care utilization. We studied this association in a cohort of 1001 consecutive kidney transplants. METHODS We retrospectively reviewed 2011-2015 data from a prospectively-maintained kidney transplant database from a single center. RESULTS A total of 1001 patients underwent kidney transplant, and were dismissed from the hospital in 3 groups: Early [≤2 days] (19.8%), Normal [3-7 days] (79.4%) and Late [>7 days] (3.8%). 34.8% of patients had living donor transplants (Early 51%, Normal 31.4%, Late 18.4%, P < 0.001). Early patients had lower delayed graft function rates (Early 19.2%, Normal 32%, Late73.7%, P = 0.001). By the hospital dismissal group, there were no differences in readmissions or emergency room visits at 30 or 90 days. Glomerular filtration rate at 12 months and rates of biopsy-proven acute rejection were also similar between groups. The timing of hospital dismissal was not associated with the risk-adjusted likelihood of readmission. Early and Normal patients had similar graft and patient survival. Late dismissal patients, who had higher rates of cardiovascular complications, had significantly higher late mortality versus Normal dismissal patients in unadjusted and risk-adjusted models. CONCLUSION Dismissing patients from the hospital 2 days after kidney transplant is safe, feasible, and improves value. It is not associated with excess health care utilization or worse short or long-term transplant outcomes.

Aim of the study is the description of the successful management of gastroepiploic artery pseudoaneurysm with preservation of parent vessels using flow-diversion technology. The present report describes the application of a flow-diversion Pipeline™ Flex device for occlusion of a sidewall bleeding pseudoaneurysm on a patient who was status-post sub-total pancreatectomy and remote esophagectomy with a gastric conduit. The pseudoaneurysm was on the solitary vessel supplying the patient's conduit. Use of flow diversion technology excluded the sidewall pseudoaneurysm while maintaining gastric conduit perfusion. In our case, the application of flow diversion technology allowed the preservation of patency of the main arterial supply to the gastric conduit on a post-esophagectomy patient; loss of the right gastroepiploic artery in that case would had been otherwise catastrophic. Flow-diversion technology can be considered for the treatment of pseudoaneurysms post-pancreatic resections, especially when there is no other surgical or endovascular treatment option.

Donation after circulatory death (DCD) liver transplantation (LT) outcomes have been attributed to multiple variables, including procurement surgeon recovery techniques. Outcomes of 196 DCD LTs at Mayo Clinic Arizona were analyzed based on graft recovery by a surgeon from our center (transplant procurement team [TPT]) versus a local procurement surgeon (non-TPT [NTPT]). A standard recovery technique was used for all TPT livers. The recovery technique used by the NTPT was left to the discretion of that surgeon. A total of 129 (65.8%) grafts were recovered by our TPT, 67 (34.2%) by the NTPT. Recipient age (p = 0.43), Model for End-Stage Liver Disease score (median 17 vs. 18; p = 0.22), and donor warm ischemia time (median 21.0 vs. 21.5; p = 0.86) were similar between the TPT and NTPT groups. NTPT livers had longer cold ischemia times (6.5 vs. 5.0 median hours; p 0.001). Early allograft dysfunction (80.6% vs. 76.1%; p = 0.42) and primary nonfunction (0.8% vs. 0.0%; p = 0.47) were similar. Ischemic cholangiopathy (IC) treated with endoscopy occurred in 18.6% and 11.9% of TPT and NTPT grafts (p = 0.23). At last follow-up, approximately half of those requiring endoscopy were undergoing a stent-free trial (58.3% TPT; 50.0% NTPT; p = 0.68). IC requiring re-LT in the first year occurred in 0.8% (n = 1) of TPT and 3.0% (n = 2) of NTPT grafts (p = 0.23). There were no differences in patient (hazard ratio [HR], 1.95; 95% confidence interval [CI], 0.76-5.03; p = 0.23) or graft (HR, 1.99; 95% CI, 0.98-4.09; p = 0.10) survival rates. Graft survival at 1 year was 91.5% for TPT grafts and 95.5% for NTPT grafts. Excellent outcomes can be achieved using NTPT for the recovery of DCD livers. There may be an opportunity to expand the use of DCD livers in the United States by increasing the use of NTPT.

BACKGROUND AND OBJECTIVES We aimed to determine outcomes with transplanting kidneys from deceased donors with severe acute kidney injury requiring acute renal replacement therapy (RRT). MATERIALS AND METHODS A total of 172 recipients received a kidney from donors with acute kidney injury stage 3 (AKIN3) requiring RRT. We compared the study group to 528 recipients who received a kidney from donors with AKIN stage 3 not on RRT and 463 recipients who received

Biliary strictures can be a challenging clinical problem to manage and often have unclear etiologies, including benign and malignant causes. Left untreated, these problems can lead to significant morbidity and mortality linked to their underlying diagnosis. The approach to adult patients with biliary strictures requires a multidisciplinary team involving surgeons, interventional endoscopists, and interventional radiologists for diagnosis, symptom relief, palliation, as well as potential curative management. From a surgeon's perspective, there are many ways to classify and approach these strictures. It is of paramount importance to start with an excellent understanding of the patient's prior surgical history. In approaching a patient with a new diagnosis of biliary stricture, it is also critical to understand its etiology relatively quickly, as 70% are malignant in the adult population. Concurrently, one must clearly define the location and extent of the stricture: intrahepatic, hilar, or distal extrahepatic bile duct, as well as whether it is a singular lesion or multifocal phenotypes. This information provides a path forward in clinical decision-making regarding durability and efficacy of therapy, which is typically aimed at decompression and/or surgical resection to prevent cholangitis, sepsis, and progressive hepatic insufficiency.

During 2001–2015, numbers of donation after circulatory death (DCD) liver transplantations (LTs) remained surprisingly low. Post-transplant outcomes improved overall over time, regardless of centre volume. High-volume centres that promoted DCD LT significantly shortened their waiting list time, therefore limiting waiting list mortality and drop-outs.

BACKGROUND Opioids are associated with negative transplant outcomes. We sought to identify patient and center effects on over-prescribing of opioids (> 200 OME (oral morphine equivalents)). STUDY DESIGN Clinical and opioid prescription data (2014-2017) were collected from three academic transplant centers for kidney (KT), liver (LT), and simultaneous liver-kidney transplant (SLK) patients. Multivariable models were used to identify predictors of opioid over-prescribing at discharge and the occurrence of refill prescriptions at 90 days. RESULTS Three-thousand seven-hundred and two patients underwent transplant in the cohort (KT: n = 2358, LT: n = 1221, SLK: n = 123). More than 80% of recipients were over-prescribed opioids at discharge (Median OME (mOME) = 300 (IQR 225-375). LT and SLK had the largest prescription size (LT mOME 338 (IQR 300-450); SLK mOME 338 (IQR 225-450) and refill rate (LT: 64%, SLK 59%) (all, P

The optimal care for the transplant candidate is to receive a timely organ transplant. Effective organ donation is critical to this equation. Organ procurement organizations (OPOs) are responsible for: 1) ensuring organ donation occurs by identifying potential donors, obtaining consent, and executing organ allocation/distribution processes, and 2) that organs are recovered safely and efficiently to allow timely transplantation.

INTRODUCTION The population of patients with cirrhosis is growing and shifting toward a more elderly demographic and thus are at risk of developing orthopedic complications. There is lack of data on safety of orthopedic procedures in this population. METHODS We performed an analysis of the Nationwide Inpatient Sample from 2005 to 2011 for patients undergoing hip arthroplasty, knee arthroplasty, and spinal laminectomy/fusion, stratified by presence of cirrhosis. The primary endpoint was in-hospital mortality and secondary endpoints included length of stay (LOS) and costs. RESULTS There were 693,610 inpatient stays for orthopedic procedures conducted during the study period, with 3014 (0.43%) patients coded as having cirrhosis. Patients with cirrhosis had a lower median age (62 vs. 66 y; P

Kidneys from deceased donors with acute kidney injury (AKI) are more likely to be discarded because of concerns for poor outcomes after transplantation. The aim of this study was to determine the long-term outcomes of a large cohort of patients transplanted utilizing kidneys from deceased donors with AKI.All patients receiving a deceased donor kidney transplant during a recent 10-year period were included. Acute Kidney Injury Network (AKIN) criteria were used to classify the donors. Donor kidneys with10% cortical necrosis or more than mild chronic changes were discarded. The primary outcome is the combined endpoint of death or graft loss.The cohort included 1313 kidneys from 974 donors, AKIN stage 0 (no AKI) in 319 (24.3%), stage 1 in 370 (28.2%), stage 2 in 177 (13.5), and stage 3 in 447 (34.0%). Estimated 5-year graft survival (95% confidence interval) was 78.5% (72.5-84.5), 77.8% (72.8-82.1), 83.8% (76.8-88.9), and 84.6% (79.5-88.7) for AKIN donor stage 0 to 3, respectively (log-rank P = 0.10). After adjusting for baseline differences, the hazard ratio (95% confidence interval) for the combined endpoint for the AKIN stage 3 group (relative to AKIN 0 group) was 0.70 (0.45-1.10). Delayed graft function occurred in 44.6% and 75.4% of AKIN 2 and 3 groups, as compared to 33.9% and 33.5% in AKIN 0 and 1 (P0.001).We conclude that transplanting selected kidneys from deceased donors with AKI with preimplantation biopsy showing10% cortical necrosis and no more than mild chronic changes have excellent long-term graft survival.

With an increasing demand for donor organs, strategies to increase the number of available donor organs have become more focused. Compensating donors for donation is one strategy proposed to increase the availability of organs for transplant. This has been implemented in several systems internationally, but debate continues in the United States with respect to appropriate strategies. The National Organ Transplant Act (NOTA) currently prohibits the transfer of any human organ 'for valuable consideration' for transplantation, but allows for the removal of financial disincentives.Several proposals currently exist for compensating patients for living donation. Recent data have focused on studying and creating mechanisms for reimbursement of costs incurred as part of the donation process, which is related to the removal of disincentives to living donation. Others have advocated for the provision of actual incentives to patients for the act of donating, in an attempt to further expand living donation. The current debate focuses on what measures can reasonably be taken to increase donation, and whether additional incentives will encourage more donation or reduce the motivation for altruistic donation.Currently, the transplant community broadly supports the removal of disincentives for living donors, including reimbursement of expenses for travel, housing and lost wages incurred during evaluation, surgery and after care. Others have advocated for financial incentives to further increase the number of donor organs available for transplant. Although the removal of disincentives is currently allowed under the existing legal structure of NOTA, providing financial incentives for living donation would require further evaluation of the economics, law, ethics and public readiness for a significant policy shift.

To investigate the outcomes of radiation segmentectomy (RS) versus standard-of-care surgical resection (SR).A multisite, retrospective analysis of treatment-naïve patients who underwent either RS or SR was performed. The inclusion criteria were solitary hepatocellular carcinoma ≤8 cm in size, Eastern Cooperative Oncology Cohort performance status of 0-1, and absence of macrovascular invasion or extrahepatic disease. Target tumor and overall progression, time to progression (TTP), and overall survival rates were assessed. Outcomes were censored for liver transplantation.A total of 123 patients were included (RS, 57; SR, 66). Tumor size, Child-Pugh class, albumin-bilirubin score, platelet count, and fibrosis stage were significantly different between cohorts (P ≤ .01). Major adverse events (AEs), defined as grade ≥3 per the Clavien-Dindo classification, occurred in 0 patients in the RS cohort vs 13 (20%) patients in the SR cohort (P .001). Target tumor progression occurred in 3 (5%) patients who underwent RS and 5 (8%) patients who underwent SR. Overall progression occurred in 19 (33%) patients who underwent RS and 21 (32%) patients who underwent SR. The median overall TTP was 21.9 and 29.4 months after RS and SR, respectively (95% confidence interval [CI], 15.5-28.2 and 18.5-40.3, respectively; P = .03). Overall TTP subgroup analyses showed no difference between treatment cohorts with fibrosis stages 3-4 (P = .26) and a platelet count of150 × 10RS and SR were performed in different patient populations, which limits comparison. RS approached SR outcomes, with a lower incidence of major AEs, in patients who were not eligible for hepatectomy.

Kidney transplant (KT) outcomes from high kidney donor profile index (KDPI ≥85%) donors with acute kidney injury (AKI) remain underreported. KT from 172 high KDPI Acute Kidney Injury Network (AKIN) stage 0-1 donors and 76 high KDPI AKIN stage 2-3 donors from a single center were retrospectively assessed. The AKIN 2-3 cohort had more delayed graft function (71% vs. 37%, p

Background The volume-mortality association led to regionalization recommendations for pancreatic surgery. Mortality following pancreatectomy has declined, but case-volume thresholds remain unchanged. Methods Patients undergoing pancreatectomy from 2004 to 2013 were identified in the National Cancer Database (NCDB). Hospitals were divided into low (LV), medium (MV), and high-volume (HV) strata using 30-day mortality quartiles and logistic regression with cubic splines. Adjusted absolute difference and odds of 30-day mortality between strata were calculated. Results Annual volumes for LV, MV, and HV were 18 cases using quartiles and 18 using cubic splines. Absolute 30-day mortality trended downwards, with differential improvements for MV and LV. Benchmark 30-day mortality for hospitals with >18 cases was 2.8%. For this benchmark, the case-volume threshold decreased from 31 in 2004 to 6 in 2013. Conclusion Differential improvement in 30-day mortality at LV and MV hospitals led to similar 30-day mortality odds at MV and HV hospitals by 2013.
