Since Italian liver allocation policy was last revised (in 2012), relevant critical issues and conceptual advances have emerged, calling for significant improvements. We report the results of a national consensus conference process, promoted by the Italian College of Liver Transplant Surgeons (for the Italian Society for Organ Transplantation) and the Italian Association for the Study of the Liver, to review the best indicators for orienting organ allocation policies based on principles of urgency, utility, and transplant benefit in the light of current scientific evidence. MELD exceptions and hepatocellular carcinoma were analyzed to construct a transplantation priority algorithm, given the inequity of a purely MELD‐based system for governing organ allocation. Working groups of transplant surgeons and hepatologists prepared a list of statements for each topic, scoring their quality of evidence and strength of recommendation using the Centers for Disease Control grading system. A jury of Italian transplant surgeons, hepatologists, intensivists, infectious disease specialists, epidemiologists, representatives of patients’ associations and organ‐sharing organizations, transplant coordinators, and ethicists voted on and validated the proposed statements. After carefully reviewing the statements, a critical proposal for revising Italy's current liver allocation policy was prepared jointly by transplant surgeons and hepatologists.

Pediatric liver transplantation

Donor-derived infections due to multidrug-resistant bacteria are a growing problem in solid organ transplantation, and optimal management options are not clear. In a 2-year period, 30/214 (14%) recipients received an organ from 18/170 (10.5%) deceased donors with infection or colonization caused by a carbapenem-resistant gram-negative bacteria that was unknown at the time of transplantation. Among them, 14/30 recipients (47%) received a transplant from a donor with bacteremia or with infection/colonization of the transplanted organ and were considered at high risk of donor-derived infection transmission. The remaining 16/30 (53%) recipients received an organ from a nonbacteremic donor with colonization of a nontransplanted organ and were considered at low risk of infection transmission. Proven transmission occurred in 4 of the 14 high-risk recipients because donor infection was either not recognized, underestimated, or not communicated. These recipients received late, short or inappropriate posttransplant antibiotic therapy. Transmission did not occur in high-risk recipients who received appropriate and prompt antibiotic therapy for at least 7 days. The safe use of organs from donors with multidrug-resistant bacteria requires intra- and inter-institutional communication to allow appropriate management and prompt treatment of recipients in order to avoid transmission of infection.

This report contains clinically oriented guidelines for the diagnostic work-up and follow-up of cystic pancreatic neoplasms in patients fit for treatment. The statements were elaborated by working groups of experts by searching and analysing the literature, and then underwent a consensus process using a modified Delphi procedure. The statements report recommendations regarding the most appropriate use and timing of various imaging techniques and of endoscopic ultrasound, the role of circulating and intracystic markers and the pathologic evaluation for the diagnosis and follow-up of cystic pancreatic neoplasms.

End-stage cholestatic liver disease (ESCLD) is the main indication for liver replacement in children. Pediatric cadaver–organ-donor shortage has prompted the most important evolutions in the technique of liver transplantation, in particular living-donor liver transplantation (LDLT) and split-liver transplantation (SLT). Between November 1997 and June 2001, 127 children with ESCLD were evaluated for liver transplantation, and 124 underwent 138 liver transplantations after a median time of 40 days. Causes of liver disease were congenital biliary atresia (n=96), Alagille’s syndrome (n=12), Byler’s disease (n=8), and other cholestatic diseases (n=8). Ninety (73%) patients received a split-liver graft, 28 (23%) a whole liver, and 6 (4%) a reduced-size liver. Overall 2- and 4-year patient survival rates were 93% and 91%, respectively; the 2- and 4-year graft-survival rates were 84% and 80%, respectively. In split-liver recipients, 4-year patient and graft-survival rates were 91% and 83%, respectively; these were 93% and 78%, respectively, in whole-liver recipients and 67% and 63%, respectively, in reduced-size liver recipients. Retransplantation rate was 11%, whereas mortality rate was 8%. Overall incidence of vascular and biliary complication were 16% and 27%, respectively. SLT can provide liver grafts for children with ESCLD with an outcome similar to the one reported following LDLT, eliminating mortality while they are on a transplantation wait list. The need for pediatric LDLT should be reevaluated and programs of SLT strongly encouraged and supported at a national and international level.

To implement split liver transplantation(SLT) a mandatory‐split policy has been adopted in Italy since August 2015: donors aged 18‐50 years at standard‐risk are offered for SLT, resulting in a left‐lateral segment(LLS) graft for children and an extended‐right graft(ERG) for adults. We aim to analyse the impact of the new mandatory‐split policy on liver transplantation(LT)‐waiting list and SLT outcomes, compared to old allocation policy. Between August 2015‐December 2016 out of 413 potentially “splittable” donors, 252(61%) were proposed for SLT, of whom 53(21%) donors were accepted for SLT while 101(40.1%) were excluded because of donor characteristics and 98(38.9%) for absence of suitable paediatric recipients. The SLT rate augmented from 6% to 8.4%. Children undergoing SLT increased from 49.3% to 65.8%(p=0.009) and the paediatric LT‐waiting list time dropped [229(10‐2121) vs. 80(12‐2503) days(p=0.045)]. The paediatric [4.5% vs. 2.5%(p=0.398)] and adult [9.7% to 5.2%(p20kg(HR=5.113, p=0.048) in LLS, and ischemic time >8hours(HR=2.475,p=0.048) in ERG were identified as predictors of graft failure. A national mandatory‐split policy maximizes the SLT donor resources, whose selection criteria can be safely expanded, providing favourable impact on the paediatric LT‐waiting list and priority for adult sick LT candidates.
