Biliary strictures post pediatric liver transplantation-incidence and risk factors in a single tertiary referral transplant center. Pediatr Transplant 2024; 28:e14727. [PMID: 38613151 DOI: 10.1111/petr.14727] [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: 10/23/2023] [Revised: 02/14/2024] [Accepted: 02/15/2024] [Indexed: 04/14/2024]
Abstract
BACKGROUND Biliary strictures are a significant cause of morbidity and graft loss in pediatric liver transplant recipients. Risk factors for the development of biliary strictures are not fully established. We aimed to evaluate the incidence of biliary strictures and treatment modalities outcomes and to identify potential risk factors for occurrence. METHODS Pediatric patients who underwent liver transplantation in the single tertiary pediatric liver transplant center in Israel were evaluated. We compared demographics, presentation, laboratory results, imaging, treatment, and outcomes between patients with and without biliary stricture. Multivariate regression analyses were used to identify risk factors for biliary strictures. RESULTS Among 121 pediatric liver transplant patients, 65 (53.7%) were males; the median age at the time of liver transplantation was 43 (3-215) months. Fifteen patients (12.4%) had biliary strictures following transplantation. One (7%) patient with biliary stricture was treated via endoscopic retrograde cholangiopancreatography, and 12 patients (80%) underwent interventions via a percutaneous transhepatic approach. Nine of the 12 patients were treated successfully, requiring one or multiple procedures, while the remaining had surgery or laser therapy. Risk factors for the development of biliary strictures were biliary leak, acute cellular rejection, and the presence of two biliary anastomoses. CONCLUSIONS In our cohort, the presence of two biliary anastomoses and post-transplant complications including acute cellular rejection and early biliary leaks were associated with biliary strictures in pediatric liver transplantation recipients. Percutaneous transhepatic interventions result in good outcomes in most patients.

Evaluation and management of biliary complications after pediatric liver transplantation: pearls and pitfalls for percutaneous techniques. Pediatr Radiol 2022; 52:570-586. [PMID: 34713322 DOI: 10.1007/s00247-021-05212-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 08/16/2021] [Accepted: 09/16/2021] [Indexed: 10/20/2022]
Abstract
In pediatric liver transplantation, bile duct complications occur with a greater incidence than vascular anastomotic dysfunction and represent a major source of morbidity and mortality. While surgical re-anastomosis can reduce the need for retransplantation, interventional radiology offers minimally invasive and graft-saving therapies. The combination of small patient size and prevailing Roux-en-Y biliary enteric anastomotic techniques makes endoscopic retrograde cholangiopancreatography difficult if not impossible. Expertise in percutaneous management is therefore imperative. This article describes post-surgical anatomy, pathophysiology and noninvasive imaging of biliary complications. We review percutaneous techniques, focusing heavily on biliary access and interventions for reduced liver grafts. Subsequently we review the results and adverse events of these procedures and describe conditions that masquerade as biliary obstruction.

Abstract
BACKGROUND To evaluate the efficacy of percutaneous and endoscopic therapeutic interventions for biliary strictures and leaks following LT in children. METHODS Retrospective analysis of 49 consecutive pediatric liver transplant recipients (27 girls, 22 boys, mean age at transplant 3.9 years) treated at our institution from 1989 to 2019 for biliary leak and/or biliary stricture was performed. Minimally invasive approach was considered clinically successful if it resulted in patency of the narrowed biliary segment and/or correction of the biliary leak. RESULTS Forty-two patients had a stricture at the biliary anastomosis; seven had a biliary leak. After an average 13.8 years of follow-up, long-term clinical success with minimally invasive treatment (no surgery or re-transplant) was achieved for 24 children (57%) with biliary stricture and 4 (57%) with biliary leaks. Eight patients required re-transplant; however, only one was due to failure of both percutaneous and surgical management. For biliary strictures, failure of non-surgical management was associated with younger age at stricture diagnosis (p < .02). CONCLUSIONS Percutaneous and endoscopic management of biliary strictures and leaks after LT in children is associated with a durable result in >50% of children.

Serum bile acid levels assist the prediction of biliary stricture and survival after liver transplantation in children. Eur J Pediatr 2021; 180:2539-2547. [PMID: 33963902 DOI: 10.1007/s00431-021-04098-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 04/28/2021] [Accepted: 04/30/2021] [Indexed: 10/25/2022]
Abstract
Biliary stricture is an important biliary complication after liver transplant in children. We aimed to investigate the utility of serum bile acid levels for prediction of biliary stricture in children after liver transplant. This study enrolled 60 children who underwent liver transplantation at a mean age of 2.04±0.30 years; serum bile acid levels were surveyed in a cross-sectional design. These patients were followed regularly at our institute, and the clinical data were collected prospectively. The major indication of liver transplant in this pediatric cohort was biliary atresia (78.33%). During the follow-up period (3.08±0.30 years), nine patients (15%) developed biliary stricture after the check of serum bile acid. A receiver operating characteristic curve analysis yielded a serum bile acid cutoff of >40 μM for the prediction of biliary stricture (P = 0.002). A serum bile acid level >40 is the most important predictor of a biliary stricture after liver transplant (odds ratio=65.65, P = 0.003) after adjusting for gender and GGT levels. The phenomenon remained on Cox's proportional hazard survival analysis (hazard ratio =15.42, P = 0.001). The mortality risk after liver transplant was significantly higher in subjects with serum bile acid levels >40 μM than in those with levels ≤40 μM (log-rank test, P = 0.004).Conclusion: Serum bile acid levels can be used for non-invasive screening and prediction of biliary stricture and mortality in children after liver transplantation. What is Known: • Biliary stricture is a major biliary complication after pediatric liver transplantation, and we showed the serum bile acid level significantly associates with biliary stricture. What is New: • In this study, we demonstrated the serum bile acid level may assist in the early detection of biliary stricture and mortality non-invasively.

Abstract
BACKGROUND The incidence and several risk factors of biliary complication (BC) following pediatric liver transplantation (LT) are widely known, but data on long-term outcomes and management is limited. This retrospective study aimed to investigate the incidence, associated risk factors, management, and outcomes of early and late BC in pediatric LT. METHODS This study enrolled 134 pediatric patients (< 18 years old) who underwent LT at a tertiary care center in Taiwan between January 2001 and December 2015. Diagnosis of BC was based on clinical, biochemical, and radiologic examinations. Clinical data and chart records were reviewed and compared between the groups. RESULTS Among the 134 children, 21 children (15.7%) had BC after LT. Nine children had early complications, including leakage plus stricture (n = 2), stricture only (n = 2), and leakage only (n = 5). Twelve children had late BC; all of whom had anastomotic stricture. Of the 21 patients with BC, 11 patients (52.4%) were treated without surgery. The median time of first treatment for BC was 6.5 months (range, 11 days to 6.2 years). Five of the 9 patients with early complications and two of the 12 patients with late complications died of biliary tract infection. The major risk factors of BC in pediatric LT were (1) recipient age > 2 years, (2) Kasai portoenterostomy revision, and (3) hepatic artery thrombosis. CONCLUSIONS Several risk factors of BC in pediatric LT were identified. Children with early BC appeared to have relatively unfavorable outcomes. However, late BC treated by either radiological or surgical methods appeared to have a relatively good long-term prognosis.

Hepatoblastoma: Transplant Versus Resection Experience in a Latin American Transplant Center. Transplant Direct 2017; 3:e165. [PMID: 28620649 PMCID: PMC5464784 DOI: 10.1097/txd.0000000000000685] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2017] [Accepted: 04/07/2017] [Indexed: 11/26/2022] Open
Abstract
Background Hepatoblastoma is the most common primary malignant liver tumor in children and is usually diagnosed during the first 3 years of life. Overall survival has increased 50% due to chemotherapeutic schemes, expertise surgery centers, and liver transplantation. Methods A retrospective collection of data was performed from pediatric patients with diagnosis of hepatoblastoma. Variables included demographic, diagnostic tools and histological classification; chemotherapy and surgical treatment; and outcomes and patient survival. The PRETEXT classification was applied, which included the risk evaluation, and according to the medical criterion in an individualized way, underwent resection or transplant. The morbidity of patients was evaluated by the Clavien-Dindo classification. Statistical analysis was performed according to the distribution of data and the survival analysis was carried out using the Kaplan-Meier method. Results The patients (n = 16) were divided in a resection group (n = 8) and a transplant group (n = 8). The median age at the time of diagnosis was 13.5 months. The motive for the initial consultation was the discovery of a mass; all patients had high levels of α-fetoprotein and an imaging study. Ten of 16 patients required chemotherapy before the surgical procedure. In the resection group, 5 of 8 patients were classified as Clavien I and 4 of 8 patients of the transplant group were classified as Clavien II. Patient survival at 30 months was 100% in the resection group and 65% in the liver transplantation group. Conclusions To our knowledge, this is the first case report of pediatric patients with hepatoblastoma and liver resection or transplant in Colombia and Latin America. Our results are comparable with the series worldwide, showing that resection and transplant increase the survival of the pediatric patients with hepatoblastoma. It is important to advocate for an increase of reporting in the scientific literature in Latin America.
