Abstract
Liver transplantation is a life-saving treatment for children who are in liver failure. The survival rate index is used to assess the success rate of liver transplantation. The study aimed to assess the survival rate of liver transplantation in children. We searched 5 international databases in this study, including Medline/PubMed, ProQuest, Scopus, Web of Knowledge, and Google Scholar, for published articles by the end of 2020. Also, meta-regression analysis was performed based on the year of the study, and subgroup analysis was performed according to continents. A total of 425 titles were reviewed. Based on the results, 96 articles were entered in the meta-analysis. Established on the random-effect model, the survival rates of 1, 3, 5, and 10 years of transplantation were 86.62%, 77.74%, 73.95%, and 68.60%, respectively. Also, based on the meta-regression results, there was a relationship between the year of the study and the survival rate, as the study year gets more recent, the survival rate is increased. This study can provide documented and comprehensive evidence which can be the basis of many policies and decisions in various sectors of health development, including evaluating treatment options and health interventions in transplantation.

Whole liver transplantation in children under 10 kg: How to minimize the high risks of a still challenging procedure. Pediatr Transplant 2022; 26:e14222. [PMID: 34994042 DOI: 10.1111/petr.14222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Revised: 12/08/2021] [Accepted: 12/24/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Whole liver transplantation in infants <10 kg is a rare procedure with moderate outcomes (67%-79% graft survival at 1 year) and high rates of vascular complications (hepatic artery thrombosis 5-26%). METHODS Retrospective single-center analysis of whole liver transplantation in infants <10 kg and systematic review of the literature focused on survival rates and surgical complications. RESULTS Between January 2005 and December 2020, 175 liver transplantations in 173 children were performed at our center. A total of 92 (53%) children weighed less than 10 kg; 19 (21%) of them underwent WLT and constitute the study population. Median age of the recipients was 10 months (21 days-24 months) and median body weight 6.5 (3.1-9.8) kg. Median age of the donors was 5 (1-84) months and median body weight 6.1 (4-21) kg. Median donor-to-recipient body weight ratio was 1.2 (range: 0.6-4.5). Postoperatively, neither hepatic artery nor portal vein thrombosis occurred. A biliary complication occurred in 4 cases: 1 bile leak (early), 3 anastomotic stenoses (1 delayed and 2 late), and 1 non-anastomotic stenosis (late). Patient survival rate at 1, 5, and 10 years was 100%, 92%, and 92%, respectively. Overall, death-censored graft survival after 1, 5, and 10 was 100%. CONCLUSION Our results are excellent in terms of complications and graft and patient survival. This involves not only high-end surgical performance but also close interdisciplinary perioperative cooperation based on strong standard operating procedures and mainly focused on fluid management, hemostasiology, and strict monitoring of vessel patency.

Abstract
Context-The imbalance between the organ supply and the number of potential transplant recipients led to consideration of expanded-criteria liver donors. Objective-To compare right-lobe split-liver transplants (RL-SLTs) with orthotopic liver transplants (OLTs) from donors more than 70 years old (OLT-O) and OLTs from donors less than 55 years old (OLT-Y). Methods-Seventy-one patients who received an RL-SLT were matched for age, sex, and Model for End-stage Liver Disease score with 71 patients who underwent OLT-O and 142 patients who underwent OLT-Y. Clinical outcomes were compared between groups. Results-Longer operation time was associated with RL-SLT (P< .001) as well as more blood loss (P= .03) and transfusions (P= .05). Postoperative morbidity was less in the OLT-Y group, with a lower rate of grades III to IV Clavien-Dindo complication (30%), compared with values in OLT-O (52%) and RL-SLT (38%). Kaplan-Meier analysis demonstrated better 1-year and 3-year survival rates in the OLT-Y group (97% and 92%, respectively), compared with 92% and 86.3%, respectively, in the RL-SLT group; and 84.5% and 73%, respectively, in the OLT-O group (P = .03). Kaplan-Meier analysis also demonstrated differences between the groups in terms of 1-year and 3-year graft survival rates, which were 92% and 86%, respectively, in OLT-Y; 77% and 66%, respectively, in the OLT-O, and 84.2% and 76.6%, respectively, in the RL-SLT group (P= .01). Conclusion-Even if OLT-Y guarantees better patient and graft survival, both RL-SLT and OLT-O can be used safely to expand the pool of liver donors, showing acceptable clinical results and complications rates.

Abstract
During the last couple of decades, with standardization and progress in surgical techniques, immunosuppression and post liver transplantation patient care, the outcome of liver transplantation has been optimized. However, the principal limitation of transplantation remains access to an allograft. The number of patients who could derive benefit from liver transplantation markedly exceeds the number of available deceased donors. The large gap between the growing list of patients waiting for liver transplantation and the scarcity of donor organs has fueled efforts to maximize existing donor pool and identify new avenues. This article reviews the changing pattern of donor for liver transplantation using grafts from extended criteria donors (elderly donors, steatotic donors, donors with malignancies, donors with viral hepatitis), donation after cardiac death, use of partial grafts (split liver grafts) and other suboptimal donors (hypernatremia, infections, hypotension and inotropic support).

Abstract
Because of organ shortage and a constant imbalance between available organs and candidates for liver transplantation, expanded criteria donors are needed. Experience shows that there are wide variations in the definitions, selection criteria, and use of expanded criteria donors according to different geographic areas and different centers. Overall, selection criteria for donors have tended to be relaxed in recent years. Consensus recommendations are needed. This article reports the conclusions of a consensus meeting held in Paris in March 2007 with the contribution of experts from Europe, the United States, and Asia. Definitions of expanded criteria donors with respect to donor variables (including age, liver function tests, steatosis, infections, malignancies, and heart-beating versus non-heart-beating, among others) are proposed. It is emphasized that donor quality represents a continuum of risk rather than "good or bad." A distinction is made between donor factors that generate increased risk of graft failure and factors independent of graft function, such as transmissible infectious disease or donor-derived malignancy, that may preclude a good outcome. Updated data concerning the risks associated with different donor variables in different recipient populations are given. Recommendations on how to safely expand donor selection criteria are proposed.

Abstract
The need for evidence-based practice guidelines requires high quality, carefully controlled clinical research trials. This multidisciplinary conference attempted to: identify urgent clinical and research issues, identify obstacles to performing clinical trials, develop concepts for organ-specific and all-organ research and generate a report that would serve as a blueprint for future research initiatives. A few themes became evident. First, young children present a unique immunologic environment which may lead to tolerance, therefore, including young children in immunosuppression withdrawal and tolerance trials may increase the potential benefits of these studies. Second, adolescence poses significant barriers to successful transplantation. Non-adherence may be insufficient to explain poorer outcomes. More studies focused on identification and prevention of non-adherence, and the potential effects of puberty are required. Third, the relatively naive immune system of the child presents a unique opportunity to study primary infections and alloimmune responses. Finally, relatively small numbers of transplants performed in pediatric centers mandate multicenter collaboration. Investment in registries, tissue and DNA repositories will enhance productivity. The past decade has proven that outcomes after pediatric transplantation can be comparable to adults. The pediatric community now has the opportunity to design and complete studies that enhance outcomes for all transplant recipients.

Abstract
OBJECTIVE To examine the outcome of technical variant liver transplant techniques relative to whole organ liver transplantation in pediatric liver transplant recipients. BACKGROUND Technical variant liver transplant techniques comprising split, reduced, and live-donor liver transplantation evolved to address the need for timely and size appropriate grafts for pediatric recipients. METHODS Analysis of data from the Studies of Pediatric Liver Transplantation (SPLIT) registry, a multicenter database of 44 North American pediatric liver transplant programs. The outcome (morbidity and mortality) of each of the technical variants were compared with that of whole organ recipients. RESULTS Data were available on 2192 transplant recipients (1183 whole, 261 split, 388 reduced, and 360 live donor). Recipients of all technical variant graft type were significantly younger than whole organ recipients, but on average spent 2.3 months less on the waiting list. Thirty-day post-transplant morbidity was increased for each type of technical variant relative to whole organ (45.1% whole, 66.7% split, 65.5% reduced, 51.9% live-donor). Biliary complications (30 day: 7.5% whole, 18.8% split, 16% reduced, 17.5% live-donor) and portal vein thrombosis (30 day: 3.6% whole, 8% split, 8% reduced, 7.5% live-donor) were more common in all technical variant types. Graft type was an independent predictor of graft loss (death or retransplantation) in a multivariate analysis. Split and reduced (relative risk = 1.74 and 1.77, respectively) grafts had a worse outcome when compared with whole organ recipients. CONCLUSIONS Technical variant techniques expand the pediatric donor pool and reduce time from listing to transplant, but they are associated with increased morbidity and mortality.

Abstract
Pediatric liver transplantation in Germany is exclusively performed in four centers in the north of Germany. We report our experience with the implementation of a new pediatric liver transplantation program in Heidelberg for children living in the south of Germany. In a pilot phase, we have transplanted eight children with various transplantation techniques including reduced size, left lateral split (segments 2 and 3), and full left split (segments 1-4). All transplantations were successful. No vascular complications occurred. The immunosuppressive regimen we used was cyclosporine A and methylprednisolone. The rate of acute rejection was three of eight patients. No patient required a retransplantation. One patient died due to a severe fungal sepsis he had acquired prior to transplantation. We conclude that in a multidisciplinary approach with careful patient selection a new program for pediatric liver transplantation can be successfully established.

Abstract
Liver transplantation has become the accepted standard of care in the treatment of a child with a failing liver. Advances in the management of critical care and immunosuppression along with the development of innovative operative procedures have improved outcome such that 5-year survival rates of 80% to 90% are expected following liver transplantation. Organ allocation schemes have evolved in an effort to better stratify recipient risk thereby more appropriately distributing deceased donor grafts. A persistent shortage of appropriate donors continues to contribute to patient mortality. The consequences of long-term immunosuppression have become increasingly apparent such that health care providers need to be aware of the side effects of chronic immunosuppression. New strategies need to be defined to minimize the need of continuous immunosuppression. The continued success of pediatric liver transplantation will require multi-disciplinary health care teams comprised of general pediatricians, pediatric hepatologists, transplant surgeons, and transplant coordinators who focus on the complex needs of the transplant recipient.

Abstract
In the past two decades, pediatric liver transplantation has become the state-of-the-art operation with anticipated success and limited mortality. The future success of pediatric liver transplantation will require thoughtful solutions to the delicate balance of risk to donors and recipients, the complex needs of the acute postoperative patient, and the long-term challenges of chronic immunosuppression in these previously unsalvageable patients.
