The aim of the study was to investigate the BiCx after the pediatric OLT and to assess the efficacy of the fluoroscopic‐guided PBI in the patients with BiCx as compared to the SR. A total of 340 OLTs were performed in 302 patients over the last 16 years. The inclusion criteria were the presence of BS or BL as a complication after OLT. The management of the BiCx was studied. Graft revision, graft loss, and survival were evaluated following PBI and SR. BiCx occurred in 17.1% (58/339) of the transplants; 6.2% (21/339) of transplants demonstrated BL and 12.7% (43/339) of the transplants had BS. Overall graft survival rates at 1 and 3 years in OLT with BL treated with PBI were 75.0% and 68.8% as compared with 75% and 66.7% in OLT treated with SR (P>.05). Overall graft survival rates at 1 and 3 years in OLT with BS treated with PBI were 70.6% and 54.5% as compared with 71.4% and 50% in OLT with SR or ERCP, respectively (P>.05). Based on the results, we conclude that PBI is as effective as SR in patients with the BL and BS after OLT. 相似文献

Biliary atresia (BA) is the most common indication for LT in children. We investigated whether this diagnosis per se, compared to other chronic liver diseases (OCLD), had an influence on patient survival. Data from 421 Scandinavian children, 194 with BA and 227 with OCLD, listed for LT between 1990 and 2010 were analyzed. The intention‐to‐treat survival and influencing risk factors were studied. Patients with BA had higher risk of death after listing than patients with OCLD. The youngest (<1 year) and smallest (<10 kg) children with the highest bilirubin (>510 μmol/L), highest INR (>1.6), and highest PELD score (>20) listed during 1990s had the worst outcome. Given the same PELD score, patients with BA had higher risk of death than patients with OCLD. For adolescents, low weight/BMI was the only prognostic marker. Impaired intention‐to‐treat survival in patients with BA was mainly explained by more advanced liver disease in younger ages and higher proportion of young children in the BA group rather than diagnosis per se. PELD score predicted death, but seemed to underestimate the severity of liver disease in patients with BA. Poor nutritional status and severe cholestasis had negative impact on survival, supporting the “sickest children first” allocation policy and correction of malnutrition before surgery. 相似文献

Auxiliary liver transplantation has been used mostly for patients with acute liver failure, but between 1980 and 2000, it has gained wider application for patients with both acute and chronic liver diseases. It is particularly applicable in patients in whom there is specific indication for removing the native liver. However, to date, very few patients have survived auxiliary liver transplantation in the long term. In this report, we describe a patient with normal liver function following heterotopic segmental auxiliary liver transplantation whom we followed for nine yr. 相似文献

The aim of our study was to determine the impact of initial orientation for medical and surgical care of children with BA on procedures and outcomes of the first LT. We retrospectively analyzed charts of children with BA who underwent first LT between 2006 and 2015. Patients were divided into two groups for comparison: a single‐center management group (from diagnosis to transplantation) and a secondarily referred group (children referred after failure of KP). We focused analysis on disease severity at transplantation, blood transfusion, and overall survival. One hundred and eighty‐five children were included. The median delay between pretransplant check‐up and transplantation was shorter in patients secondarily referred. A severe undernutrition was observed in 23.7% of children secondarily referred compared to 11.1% in children with a single‐center management (P = .024). At transplantation, INR and factor V level were higher in single‐center group patients (respectively, 67% vs 55%, P < .001 and 61% vs 49%, P = .002). The total of red blood cell and fresh frozen plasma administrated during procedure was two times higher in patients secondarily referred. Finally, patients with a single‐center management had a higher overall 12 months of survival rate (92.1% vs 83.1%, P = .033). In a country without low‐density population issues, the authors advocate an early referring to transplant center to further improving LT outcomes in children with BA. 相似文献

The effect of donor–recipient sex matching on long‐term survival in pediatric heart transplantation is not well known. Adult data have shown worse survival when male recipients receive a sex‐mismatched heart, with conflicting results in female recipients. We analyzed 5795 heart transplant recipients ≤18 yr in the Scientific Registry of Transplant Recipients (1990–2012). Recipients were stratified based on donor and recipient sex, creating four groups: MM (N = 1888), FM (N = 1384), FF (N = 1082), and MF (N = 1441). Males receiving sex‐matched donor hearts had increased unadjusted allograft survival at five yr (73.2 vs. 71%, p = 0.01). However, this survival advantage disappeared with longer follow‐up and when adjusted for additional risk factors by multivariable Cox regression analysis. In contrast, for females, receiving a sex‐mismatched heart was associated with an 18% higher risk of allograft loss over time compared to receiving a sex‐matched heart (HR 1.18, 95% CI: 1.00–1.38) and a 26% higher risk compared to sex‐matched male recipients (HR 1.26, 95% CI: 1.10–1.45). Females who receive a heart from a male donor appear to have a distinct long‐term survival disadvantage compared to all other groups. 相似文献

The treatment of biliary stenosis after pediatric LDLT is challenging. We describe an innovative technique of peripheral IHCJ for the treatment of patients with complex biliary stenosis after pediatric LDLT in whom percutaneous treatment failed. During surgery, the percutaneous biliary drainage is removed and a flexible metal stylet is introduced trough the tract. Subsequently, the most superficial aspect of the biliary tree is recognized by palpation of the stylet's round tip in the liver surface. The liver parenchyma is then transected until the bile duct is reached. A side‐to‐side anastomosis to the previous Roux‐en‐Y limb is performed over a silicone stent. Among 328 pediatric liver transplants performed between 1988 and 2015, 26 patients developed biliary stenosis. From nine patients requiring surgery, three patients who had received left lateral grafts from living‐related donors due to biliary atresia were successfully treated with IHCJ. After a mean of 45.6 months, all patients are alive with normal liver morphological and function tests. The presented technique was a feasible and safe surgical option to treat selected pediatric recipients with complex biliary stenosis in whom percutaneous procedures or rehepaticojejunostomy were not possible, allowing complete resolution of cholestasis and thus avoiding liver retransplantation. 相似文献

Historically, 9–29% of pediatric liver transplant recipients have required retransplantation. Although outcomes have improved over the last decade, currently published patient and graft survival remain lower after retransplant than after primary transplant. Data from liver retransplantation recipients at our institution between 1991 and 2013 were retrospectively reviewed. Kaplan–Meier estimates were used to depict patient and graft survival. Predictors of survival were analyzed using a series of Cox proportional hazards models. Predictors were analyzed separately for patients who had “early” (≤30 days after primary transplant) and “late” retransplants. Eighty‐four patients underwent retransplant at a median time of 241 days. Sixty percent had late retransplants. At one, five, and 10 yr, actuarial patient and graft survival were 73%/71%, 66%/63%, and 58%/53%, respectively. Since 2002, patient and graft survival improved to 86%/86% at one yr and 93%/87% at five yr. While operative complications were a common cause of death after earlier retransplants, since 2002, infection has been the only cause of death. Significant morbidities at five‐yr follow‐up include renal dysfunction (15%), diabetes (13%), hypertension (26%), chronic rejection (7%), and PTLD (2%). Current survival after pediatric liver retransplantation has improved significantly, but long‐term immunosuppressant morbidity remains an opportunity for improvement. 相似文献

Hepatoblastoma (HB) is the most common malignant liver tumor in children. Twenty percent of the cases may remain unresectable after neoadjuvant chemotherapy and, for these patients, liver transplant (LT) is an accepted therapeutic option. To analyze the risk factors to event‐free survival (EFS) that influence the clinical outcome of patients with HB receiving LT, we retrospectively analyzed 21 patients with HB who underwent LT between January 1, 2005, and May 1, 2018. Overall survival (OS) was 90%. The univariate analysis shows that the AFP level at the time of LT was associated with a higher risk of EFS. With a ROC curve analysis, we established a cutoff point value of AFP levels at 16 000 ng/dL, with a sensitivity of 71.43% and a specificity of 85.71%. Multivariate analysis showed that patients with higher values of pretransplant AFP (>16 000 ng/dL) had a significantly higher risk of EFS than those transplanted with lower levels (HR: 10.180; 95% CI: 1.54‐66.97; P = .02). Efforts should be made to improve the selection of candidates for LT for unresectable HB, aiming at a better definition of chemoresistance as a risk factor of poor outcomes. 相似文献

Orthotopic liver transplantation (Tx) has improved survival in infants with extrahepatic biliary atresia (BA) when portoenteroanastomosis fails. Symptoms leading to Tx include liver failure, poor quality of life and growth failure. The objective of the study was to determine catch-up growth in children with BA. Medical records and growth data of 36 patients (24 girls) who received a Tx due to BA were analyzed. Thirty-two patients completed 3 yr and 15 patients 7 yr of follow-up after Tx. At Tx, the median age was 2.7 yr (range 0.7-12.6) and mean height Z score (+/-s.d.) was -1.56 (+/-1.3). Patients were divided in two groups according to age at Tx: group I (n = 10), younger than 1.0 yr, and group II (n = 26) older than 1.0 yr. Median age (range) at Tx in group I was 0.8 yr (0.7-1.0) and in group II it was 3.35 yr (1.25-12.6). Thirteen patients (nine in group I) were receptors of living related donors. We evaluated linear growth, liver and renal function, immunosuppressive regimen and allograft rejection episodes. We did not find any significant differences in allograft or renal function, immunosuppressive therapy and number of acute rejection episodes or height Z score at Tx, second and third year post-Tx between both groups. The mean height Z score at Tx in group I was -1.61 and in group II -1.54; at the second year, group I -0.66 and group II -1.08; at the third year, group I -0.17 and group II -0.85; and at the seventh year (total group) -0.3. However, the height gain at the third year was better in group I than in group II (p < 0.01, t-test). Height Z score at the third year improved more than 1 SDS in seven out of eight patients in group I and in only nine out of 24 in group II (odds ratio 11.6). We also found a correlation between height gain at the third year and age at Tx (r-0.65) and between height gain at the third year and height Z score at Tx (r-0.54) (Pearson, p < 0.05). Children with BA who are transplanted before 12 months of age presented better catch-up growth without change survival and morbidity. Orthotopic liver Tx improves survival and also enables height gain in these children. 相似文献

To understand factors contributing to liver graft loss and patient death, we queried a national database designed to follow pediatric patients transplanted between 1987 and 1995 till adulthood. A comparison was made to a cohort transplanted between 2000 and 2014. The 5‐, 10‐, 15‐, 20‐, and 25‐year patient survival and graft survival were 95.5%, 93.7%, 89.1%, 80.8%, and 73.1%, and 92.5%, 86.7%, 77.6%, 68.7%, and 62.2%, respectively. The twenty‐year patient/graft survival was significantly worse in those transplanted between 5 and 17 years of age compared to those transplanted at <5 years of age (P < 0.001). For the modern era cohort, the 3‐year patient survival was significantly lower in children transplanted at 16‐17 years of age compared to those transplanted at <5 and 11‐15 years of age (P ≤ 0.02). The 3‐year graft survival was similarly lower in children transplanted at 16‐17 years of age compared to those transplanted at <5, 5‐10, and 11‐15 years of age (P ≤ 0.001). Infection as a cause of death occurred either early or >15 years post‐transplant. Chronic rejection remained the leading cause of graft loss in both cohorts and the commonest indication for retransplantation 20‐25 years following primary transplant. Further research is required to identify modifiable factors contributing to development of chronic rejection. 相似文献

HB is the most common primary liver tumor in children. Complete tumor excision, either by partial resection or by total hepatectomy and liver transplantation, in combination with chemotherapy provides the best chance for cure. We performed a retrospective analysis of patients who underwent liver transplantation for HB and herein present our 14‐year single‐institution experience. Twenty‐five patients underwent liver transplantation for HB at a median age of 26 months (IQR: 15‐44). Graft survival was 96%, 87%, and 80% at 1, 3, and 5 years, respectively. There were four patient deaths, three of them due to disease recurrence within the first year post‐transplant. Ten‐year overall survival was 84%. Three recipients initially presented with pulmonary metastases and underwent resection of metastatic disease, of which two are alive at 3.9 years. Of three patients who underwent salvage transplants, two are alive at 1.5 years after transplant. Non‐survivors were associated with lower median alpha fetoprotein value at presentation compared to survivors (21 707 vs 343 214; P = .04). In conclusion, the overall long‐term outcome of primary liver transplantation for HB is excellent. Tumor recurrence was the highest contributor to mortality. Even patients with completely treated pulmonary metastases prior to transplant demonstrated a favorable survival. 相似文献

LT has played a significant role in improving the outcome of children with BA. We review our five‐yr experience of LDLT for children with BA. Records of all children who underwent LDLT in our institution over a five‐yr period (August 2010–June 2015) were reviewed and those with a primary diagnosis of BA were selected for our study. Data were extracted from a prospectively maintained database. Additional data were collected by review of case notes and imaging studies. Analysis was carried out using standard statistical means. One hundred and thirty‐two children underwent LDLT at our center over the study period, of which 58 children (31 females) had a primary diagnosis of BA. Thirty‐three (56.9%) children had undergone a prior KPE and 25 (43.1%) had a primary LT. Thirty‐four children had at least one post‐op complication, of which 13 had minor complications (Clavien grades I and II) and 21 had major complications (Clavien grade >II). Thirty‐day survival was 96.6% and one‐yr survival was 91.4%. Univariate analysis of variables comparing children who did and did not have a KPE prior to LT showed that age at LT, weight at LT, PELD, and GRWR were significantly different. LDLT provides excellent outcomes in children with BA. Primary LDLT and LT after KPE provide equivalent results, although the former is technically more challenging as the child is younger. 相似文献

The best type of biliary anastomosis to use in lower weight pediatric liver transplant recipients is debatable. In this study, we share a single center's experience comparing the rate of anastomotic biliary complications based on the type of biliary anastomosis performed in this population of patients. A retrospective review of pediatric liver transplants for recipients weighing <15 kg from 11/2003 till 12/2011 was performed. Patients were grouped based on the type of biliary anastomosis into two groups: duct‐to‐duct (d‐d) and Roux‐en‐Y hepaticojejunostomy (h‐j) anastomoses. A total of 24 patients (12 males, 12 females) with a mean age of 26 ± 20 months and a mean weight of 9.27 ± 2.63 kg (range = 5.3–13.9 kg) were studied. All anastomotic complications occurred in patients who received left lateral segments. No statistical differences were found in the post‐operative biliary (p = 0.86) or vascular (p = 0.99) complications between the two groups. Acknowledging the limited sample size, our data suggest that duct‐to‐duct anastomosis can be performed safely in pediatric liver transplantation recipients weighing below 15 kg. 相似文献

Little is known about the achievement of developmental milestones (i.e., COL) after pediatric liver transplantation. The aim of this study was to examine the COL of young adults who underwent a liver transplantation during childhood and to compare it to healthy peers. Furthermore, we studied factors possibly related to their COL. COL was assessed using the CLQ, which assesses the achievement of developmental milestones (autonomy, psychosexual, social, and antisocial development) and risk behavior (substance abuse and gambling). Sociodemographic characteristics and clinical data were collected using the prospective institutional liver transplantation database. A total of 39 young adults who underwent a liver transplantation at the UMCG in their childhood completed the CLQ. They achieved fewer milestones with regard to autonomy, psychosexual, and social development compared to healthy peers, and they reported less risk behavior. Neither age at the time of study nor age at the time of transplantation was significantly correlated with any of the COL subscales. Young adults show delay in reaching developmental milestones in every dimension after a liver transplantation during their childhood. 相似文献

LT is a practical therapeutic alternative for unresectable hepatoblastoma; however, deciding when to perform LT is difficult. The aim of this study was to optimize the timing of LT for hepatoblastoma using pretransplant trends in AFP levels. Trends in pretransplant AFP levels and their influence on post‐transplant outcomes were retrospectively evaluated. All patients who underwent living donor LT for hepatoblastoma in our institution since 2002 were included. Variables analyzed included history of prior tumor resection, pretransplant AFP responses to chemotherapy, metastatic disease at diagnosis, and post‐transplant chemotherapy. Eight patients (seven boys and one girl; median age, 35 months; range, 15 months‐12 years) were transplanted. The overall post‐transplant recurrence‐free survival rate was 62.5% (5/8) with a mean follow‐up of 77 months. Patients with post‐transplant recurrence showed a 0.573 log increase in AFP levels after the last chemotherapy session before LT. This was significantly higher than the 0.279 log decrease observed in patients without post‐transplant recurrence (P = .024). Because the AFP response cannot be accurately predicted before each cycle of chemotherapy, it may be appropriate to perform LT when AFP levels do not decrease after the last cycle and before they are found to be elevated again. 相似文献

Background
The results obtained by protocols for children with rhabdomyosarcoma (RMS) have improved in recent decades. Survival curves usually reach a plateau 3 years after the diagnosis, suggesting that long‐term survival can be expected, but late events are known to occur. We analyzed the long‐term results of the RMS 79 protocol to investigate the type and impact of such events.Procedure
From 1979 to 1987, 163 children with RMS diagnosed at 21 Italian institutions were registered. Each institution was contacted every year to record patients' status after the end of treatment. When patients were lost to follow‐up, their status was checked by inquiring at the Registry Offices of the towns of residence and the cause of death or occurrence of second cancers was investigated by contacting the patients or their family by phone.Results
Overall, 16 patients had late events, that is, 7 tumor recurrences, 6 second tumors, and 3 deaths due to treatment‐related complications. The overall survival rates dropped from 62.6 at 3 years to 52.8 at 20 years. By multivariate analysis, the characteristics influencing long‐term survival were histology, tumor site and size, and IRS group. Factors predictive of any kind of late event were tumor site and IRS group.Conclusions
Major late events can significantly affect the long‐term survival of children with RMS. Modern protocols should provide for a much longer follow‐up than is usually considered to confirm the results achieved and enable possible correlations between primary treatment and late events to be investigated.

LDLT is indicated for a variety of metabolic disorders, primarily in Asian countries due to the absolute scarcity of deceased donor LT. We analyzed data for all pediatric LDLTs performed between November 1989 and December 2010, during which 2224 pediatric patients underwent LDLT in Japan. Of these patients, 194 (8.7%) underwent LDLT for metabolic disorders. Wilson's disease (n = 59; 30.4%) was the most common indication in the patients with metabolic disorders, followed by OTCD (n = 40; 20.6%), MMA (n = 20; 10.3%), and GSD (n = 15; 7.7%). The one‐, five‐, 10‐, and 15‐yr patient and graft survival rates were 91.2%, 87.9%, 87.0%, and 79.3%, and 91.2%, 87.9%, 86.1%, and 74.4%, respectively. Wilson's disease and urea cycle deficiency were associated with better patient survival. The use of heterozygous donors demonstrated no negative impact on either the donors or recipients. With regard to X‐linked OTCD, symptomatic heterozygote maternal donors should not be considered potential donor candidates. Improving the understanding of the long‐term suitability of this treatment modality will require the registration and ongoing evaluation of all patients with inherited metabolic disease considered for LT. 相似文献
