The impact of portal vein reconstruction on portal vein complications after pediatric living-donor liver transplantation with left lobe graft. Surgery 2023; 173:537-543. [PMID: 36424198 DOI: 10.1016/j.surg.2022.10.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 10/10/2022] [Accepted: 10/14/2022] [Indexed: 11/23/2022]
Abstract
BACKGROUND This study aimed to determine whether the different methods of portal vein reconstruction have an impact on the occurrence of portal vein complications after pediatric living-donor liver transplantation with left lobe graft. METHODS A total of 567 recipients were eligible for enrollment in this study and were divided into the following 2 groups according to the type of portal vein reconstruction: group 1 underwent anastomosis of the left and right bifurcations of the recipient portal vein to the donor portal vein (type 1), whereas group 2 underwent anastomosis of the bevel formed by the main trunk and right branch of the recipient portal vein to the donor portal vein (type 2). Postoperative portal vein complications and recipient and graft survival rates were compared between the 2 groups before and after propensity score matching. RESULTS Portal vein complications occurred in 53 (9.3%) patients, including 46 recipients with portal vein stenosis and 7 with portal vein thrombosis. After propensity score matching, the incidence of portal vein stenosis in group 2 was lower than that in group 1 (P = .035). The first diagnosis time of portal vein stenosis in group 2 was later than that in group 1 (P = .033), and the incidence of early portal vein stenosis was lower than that in group 1 (P = .009). There were no statistically significant differences in the incidence of portal vein thrombosis and recipient and graft survival rates between the 2 groups. CONCLUSIONS Type 2 portal vein reconstruction appears to be a viable technique in pediatric living-donor liver transplantation with left lobe graft that can effectively reduce the incidence of portal vein stenosis.

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.

Abstract
Background Donor shortage is an important limitation of liver transplantation (LT). Split liver transplantation (SLT) may increase the sources of donors and reduce the problem of organ shortage. However, there are no standard criteria of the selection of SLT donor, especially regarding the donor age. Methods We retrospectively analyzed the clinical data of children who received initial SLT between January 2015 and December 2021. Based on the age of donors, the patients were divided into groups A (1-10 years old; n = 26), B (10-45 years old; n = 87), and C (45-55 years old; n = 27). The short-term (<1 year after SLT) outcomes of the recipients were analyzed. Results A total of 140 patients received SLT from 122 donors. The 1-, 3- and 12-month patient survival rates in group A were 100.0%, and the graft survival rates were 92.3%. The 1-, 3- and 12-month survival rates of patient and graft in group B were 97.7%, 96.6%, and 95.0%, respectively, and in group C were 85.2%, 85.2%, and 81.1%, respectively. The patient survival rate was significantly lower in group C than in groups A and B (p = 0.0082). There was no significant difference in graft survival between the three groups (p = 0.0545). Conclusions Similar results were obtained for pediatric SLT with donors <10 years old and 10-45 years old. Pediatric SLT can be performed with older donors (45-55 years) after strict donor selection and selection of appropriate recipients.

Outflow reconstruction of left lateral graft with two widely spaced hepatic veins in pediatric living donor liver transplantation. Surgery 2022; 172:391-396. [PMID: 35210103 DOI: 10.1016/j.surg.2022.01.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 12/06/2021] [Accepted: 01/16/2022] [Indexed: 11/20/2022]
Abstract
BACKGROUND Living donor liver transplantation using the left lateral segment of the liver is the most common type of pediatric liver transplantation. An appropriate surgical approach is crucial for decreasing the risk of vascular complications using these grafts with anatomical variations. METHODS Between January 2017 and December 2020, 631 living donor liver transplantations using left lateral segment grafts were performed at Tianjin First Central Hospital. The grafts from 162 (25.7%) donors have 2 hepatic vein openings. A total number of 21 transplantations using left lateral segment grafts with 2 widely spaced hepatic vein openings were performed. In group 1, the unification venoplasty technique with interposition vein graft was used at the back table for the reconstruction of hepatic vein from grafts. In group 2, dual hepatic vein reconstructions were performed, in which venoplasty of recipients' left hepatic vein, middle hepatic vein, and inferior vena cava was performed to create a large orifice for anastomosis with segment Ⅱ hepatic vein from the graft. Segment III hepatic vein from the graft was anastomosed with the recipient's right hepatic vein. The incidence, treatment, and outcomes of hepatic venous outflow obstruction were compared between the 2 groups. RESULTS The median follow-up time was 12.8 months. There was no significant difference in the incidence of hepatic venous outflow obstruction between the 2 groups. CONCLUSION Dual hepatic vein reconstruction is an alternate surgical option for grafts with 2 widely spaced hepatic veins, and it is associated with ideal graft recovery and vascular condition. However, long-term follow-up is still needed to verify the efficacy and safety of this approach.

Living Donor Liver Transplantation vs. Split Liver Transplantation Using Left Lateral Segment Grafts in Pediatric Recipients: An Analysis of the UNOS Database. Transpl Int 2022; 36:10437.

Abstract
Split and LDLT in pediatric patients have the potential to decrease wait times and waitlist mortality. Using UNOS-STAR data, we compared outcomes of pediatric patients undergoing LDLT and SLT using LLS grafts. The baseline characteristics and post-operative outcomes were compared between groups. Actuarial graft and patient survival were analyzed with Kaplan-Meier curves. Between 2010 and 2019, 911 pediatric LT were included in the analysis (LD graft group, n = 508, split graft group, n = 403). LD graft recipients spent more time on the waitlist vs. the split graft group (60 (22–138) days vs. 46 (16–108) days; p = 0.007). LD recipients had a lower rate of graft failure, found in 9.8% of patients compared with 14.6% in the split graft group (p = 0.02). HAT was the most common graft failure cause, with similar rates. Graft and patient survival at 1-, 3-, and 5-years was comparable between LDLT and SLT. In subgroup analyses, patients with biliary atresia, those ≤10 kg or ≤10 years old receiving an LD graft showed improved graft survival. In conclusion, LDLT is associated with a lower rate of graft failure in pediatric patients. The use of LLS regardless of the type of donor is a safe way to facilitate access to transplantation to pediatric patients with acceptable short and long-term outcomes.

Abstract
Difficulty in obtaining adequate abdominal wall closure due to loss of the abdominal domain is a frequent complication of multivisceral, isolated intestinal transplantation and in some cases of liver transplantation. Various methods for primary closure have been proposed, including the use of synthetic and biological meshes, as well as full-thickness abdominal wall and non-vascularized rectus fascia grafts. We describe a novel technique for abdominal wall procurement in which the graft is perfused synchronously with the abdominal organs and can be transplanted as a full-thickness wall or as a non-vascularized rectus fascia graft. We performed six transplants of non-vascularized rectus fascia in three intestinal transplants, one multivisceral transplant, and two liver transplants. The size of the covered abdominal wall defects ranged from 17 cm × 7 cm to 25 cm × 20 cm. Only one patient developed graft infection secondary to enterocutaneous fistula requiring surgical correction and removal of the fascia graft. This patient, as well as two other patients, died due to sepsis. Our procurement technique allows removal of the rectus fascia graft to cover the abdominal wall defect, providing a feasible solution for treatment of abdominal wall defects in recipients after abdominal organ transplantation.

Abstract
The goal of this study was to evaluate the efficacy of a perioperative prophylactic strategy against de novo hepatitis B virus (HBV) infection in pediatric liver transplantation (LT) recipients with hepatitis B core antibody (HBcAb)-positive grafts. A total of 482 pediatric recipients transplanted between 2013 and 2017 were enrolled, and 170 recipients received HBcAb-positive liver grafts. The overall graft and recipient survival rates in HBcAb-positive and HBcAb-negative graft recipients were 91.8% versus 91.3% and 95.3% versus 94.2% at the end of follow-up. Preoperative hepatitis B surface antibody (HBsAb) titer ≥ 1000 IU/L and postoperative HBsAb titer ≥200 IU/L were our prophylactic targets for recipients receiving HBcAb-positive grafts. While 11 recipients developed de novo HBV infection, 10 received HBcAb-positive grafts. Both the preoperative and postoperative HBsAb targets were achieved in 78 recipients, the infection rate of de novo HBV was 1.3%; 24 recipients met the preoperative target, the infection rate was 4.2%; 52 recipients met the postoperative target, the infection rate was 1.9%; and 16 recipients met neither the preoperative nor postoperative HBsAb target, 43.8% of the recipients were infected with de novo HBV, which was significantly higher than the recipients who met both or either of the preoperative and postoperative targets. Split-liver grafts positive for HBcAb showed higher risk of de novo HBV infection. Postoperative application of lamivudine to recipients whose preoperative HBsAb titer < 1000 IU/L did not show preventive effect. Out of 11 infected recipients, 3 showed seroconversion under entecavir treatment. In conclusion, the graft and recipient survival rates were similar in pediatric LT recipients receiving HBcAb-positive or HBcAb-negative grafts. Our prophylactic strategy was effective for preventing de novo HBV infection in HBcAb-positive liver graft recipients.

Abstract
Liver transplantation is the standard treatment for children with end-stage liver disease, primary hepatic neoplasms, or liver-localized metabolic defects. Perioperative mortality is almost absent, and long-term survival exceeds 90%. Organ shortage is managed thanks to advances in organ retrieval techniques; living donation and partial liver transplantation almost eliminated waiting list mortality, thus leading to expanding indications for transplantation. The success of pediatric liver transplantation depends on the prompt and early referral of patients to transplant Centers and on the close and integrated multidisciplinary collaboration between pediatricians, hepatologists, surgeons, intensivists, oncologists, pathologists, coordinating nurses, psychologists, and social workers.

Abstract
PURPOSE To investigate the efficacy of living donor liver transplantation (LDLT) plus domino-auxiliary partial orthotopic liver transplantation (D-APOLT) in pediatric patients with metabolic disorders. METHODS From May 2017 to October 2018, two patients with ornithine aminotransferase deficiency (OTCD) and one patient with type I Crigler-Najjar syndrome (CNS1) received LDLT, their livers were prepared as donors for D-APOLT. Two patients with CNS1 received domino liver grafts from OTCD patients; one OTCD patient received a domino liver graft from a CNS1 patient. RESULTS The mean follow-up was 26.6 months. The liver function and ammonia remained in the normal range at the end of the follow-up in all recipients. One D-APOLT patient experienced portal vein thrombosis 2 days after transplantation and required reoperation, this patient presented an imbalance of portal blood perfusion between the native and the domino liver at 8 months after liver transplant. The imbalance was improved by interventional radiology treatment. Two LDLT patients experienced early mild acute rejection. CONCLUSIONS The non-cirrhotic livers from pediatric patients with metabolic liver disease can be used as domino donor grafts for selected pediatric patients with different metabolic liver disease. D-APOLT achieves ideal recipient outcomes and provides a strategy to expand donor source for children.
