Perioperative Complications After Pediatric Liver Transplantation-A Retrospective Analysis of 421 Cases. Pediatr Transplant 2024; 28:e14872. [PMID: 39385715 DOI: 10.1111/petr.14872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Revised: 08/09/2024] [Accepted: 09/26/2024] [Indexed: 10/12/2024]
Abstract
BACKGROUND Due to the low incidence of pediatric liver transplantations, short- and long-term data regarding their outcome, details on early postoperative complications and their risk factors are under-represented in the literature. METHODS We retrospectively reviewed 1645 LTx performed at Hannover Medical School between January 2005 and December 2021. Of these, 421 transplantations were performed in 405 pediatric recipients. Univariate and multivariate binary logistic regressions were performed to identify independent risk factors for the onset of selected perioperative complications requiring intervention within the first 30 days following transplantation and their influence on graft and patient survival. RESULTS Pleural effusions represent the most common postoperative complication observed in 49.4% (n = 208) of cases, followed by vascular complications in 22.6% (n = 95) and biliary complications in 20.0% (n = 84) of cases. Donor age (OR: 1.019; p = 0.010) and recipient age between 3 and 12 years (OR: 1.849; p = 0.008) were identified as independent risk factors for the onset of pleural effusions. Retransplantations within the first year after LTx were necessary in 11.4% of all cases (n = 48). Twenty (4.8%) patients died within the first year after LTx. CONCLUSION Pleural effusions requiring postoperative intervention were observed in approximately half of the pediatric recipients. Therefore, the preemptive intraoperative placement of a chest drain under sterile conditions and general anesthesia should be considered. Our data further indicate that a two-stage procedure for biliary reconstruction may be the preferred procedure in patients at risk of early bile duct complications and retransplantation within the first year.

Abstract
Background Vascular thromboses (VT) are life-threatening events after pediatric liver transplantation (LT). Single-center studies have identified risk factors for intra-abdominal VT, but large-scale pediatric studies are lacking. Methods This multicenter retrospective cohort study of isolated pediatric LT recipients assessed pre- and perioperative variables to determine VT risk factors and anticoagulation-associated bleeding complications. Results Within seven postoperative days, 31/331 (9.37%) patients developed intra-abdominal VT. Open fascia occurred more commonly in patients with VT (51.61 vs 23.33%) and remained the only independent risk factor in multivariable analysis (OR = 2.84, p = 0.012). Patients with VT received more blood products (83.87 vs 50.00%), had significantly higher rates of graft loss (22.58 vs 1.33%), infection (50.00 vs 20.60%), and unplanned return to the operating room (70.97 vs 16.44%) compared to those without VT. The risk of bleeding was similar (p = 0.2) between patients on and off anticoagulation. Conclusions Prophylactic anticoagulation did not increase bleeding complications in this cohort. The only independent factor associated with VT was open fascia, likely a graft/recipient size mismatch surrogate, supporting the need to improve surgical techniques to prevent VT that may not be modifiable with anticoagulation.

Utilization of Segmental Grafts Is Associated With Higher Transplant Rates in Pediatric Patients. J Surg Res 2023; 290:28-35. [PMID: 37178557 DOI: 10.1016/j.jss.2023.03.048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Revised: 03/03/2023] [Accepted: 03/26/2023] [Indexed: 05/15/2023]
Abstract
INTRODUCTION In July 2017, a policy to increase the use of segmental grafts (SGs) was implemented at our institution. The aim was to compare changes in waitlist activity after implementation of this policy. METHODS A single-center, retrospective study. Pediatric patients on the liver waiting list between January 2015 and December 2019 were screened. Patients were classified as receiving a liver transplant (LT) before (Period 1) or after (Period 2) policy changes. Primary end points were transplant rates and time to transplant. RESULTS Sixty five first LT performed on 65 patients were included. Twenty nine LT were performed during Period 1 and 36 during Period 2. More than half (55%) of LT in Period 2 were SG, compared to 10.3% in Period 1 (P < 0.001). Forty nine and 56 pediatric candidates on the waiting list accounted for 38.78 and 24.48 person-years during Period 1 and Period 2, respectively. Transplant rates per 100 person-years on the waiting list increased from 85.09 during Period 1 to 187.87 in Period 2 (Rate ratio: 2.20; P < 0.001). Median time to receive a LT decreased from 229 d in Period 1 to 75 d during Period 2 (P = 0.013). One-year patient survival rates were 96.6% in Period 1 and 95.7% in Period 2. One-year graft survival rates were 89.7% and 88% in Period 1 and Period 2, respectively. CONCLUSIONS A policy to increase the use of SG was associated with significantly higher transplant rates and lower waiting times. Implementation of this policy can be done successfully with no observed negative impact on patient and graft survival.

Liver Transpl 2023; 29:58-66.

Abstract
The lower limit of body weight for "splitable" liver grafts remains unknown. To examine the outcome of split-liver transplantation (SLT) from pediatric donors ≤25 kg relative to conventional graft-type liver transplantation from deceased donors under corresponding conditions, a total of 158 patients who received primary liver transplantation, including 22 SLTs from donors ≤25 kg, 46 SLTs from donors >25 kg, 76 whole-liver transplantations, and 14 reduced-liver transplantations in donors ≤25 kg between January 2018 and December 2019, were included in the study. There was no significant difference in the complications, patient survival, and graft survival between each of the latter three groups and the SLT ≤25 kg group. Pediatric End-Stage Liver Disease (PELD) score was the independent predictor of graft loss (death or retransplantation). Graft weight was the independent predictor of hepatic artery thrombosis. SLT using well-selected pediatric donors ≤25 kg is an effective strategy to increase organ availability, especially for low-body-weight recipients, compared with conventional graft type from deceased donors under the condition of corresponding donor weight without increasing morbidity and mortality.
