A European International Multicentre Survey on the Current Practice of Perioperative Antibiotic Prophylaxis for Paediatric Liver Transplantations. Antibiotics (Basel) 2023; 12:antibiotics12020292. [PMID: 36830202 PMCID: PMC9952614 DOI: 10.3390/antibiotics12020292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 01/27/2023] [Accepted: 01/30/2023] [Indexed: 02/04/2023] Open
Abstract
(1) Background: Postoperative infections are major contributors of morbidity and mortality after paediatric liver transplantation (pLTX). Evidence and recommendations regarding the most effective antimicrobial strategy are lacking. (2) Results: Of 39 pLTX centres, 20 responded. Aminopenicillins plus ß-lactamase inhibitors were used by six (30%) and third generation cephalosporins by three (15%), with the remaining centres reporting heterogenous regimens. Broad-spectrum regimens were the standard in 10 (50%) of centres and less frequent in the 16 (80%) centres with an infectious disease specialist. The duration ranged mainly between 24-48 h and 3-5 days in the absence and 3-5 days or 6-10 days in the presence of risk factors. Strategies regarding antifungal, antiviral, adjunctive antimicrobial, and surveillance strategies varied widely. (3) Methods: This international multicentre survey endorsed by the European Liver Transplant Registry queried all European pLTX centres from the registry on their current practice of perioperative antibiotic prophylaxis and antimicrobial strategies via an online questionnaire. (4) Conclusions: This survey found great heterogeneity regarding all aspects of postoperative antimicrobial treatment, surveillance, and prevention of infections in European pLTX centres. Evidence-based recommendations are urgently needed to optimise antimicrobial strategies and reduce the spectrum and duration of antimicrobial exposure.

Abstract
Objective. To review the critical care course of children receiving orthotopic liver transplantation (OLT). Methods. A retrospective chart review of patients admitted to the pediatric critical care following OLT performed in our center between 1988 and 2011. Results. A total of 149 transplants in 145 patients with a median age of 2.7 (IQR 0.9–7) years were analyzed. Mortality in the first 28 days was 8%. The median length of stay (LOS) was 7 (4.0–12.0) days. The median length of mechanical ventilation (MV) was 3 (1.0–6.2) days. Open abdomen, age, and oxygenation index on the 2nd day predicted LOS. Open abdomen, age, amount of blood transfused during surgery, and PRISM III predicted length of MV. 28% of patients had infection and 24% developed acute rejection. In recent group (2000–2011) OLT was performed in younger patients; the risk of infection and acute rejection was reduced and patients required longer LOS and MV compared with old group (1988–1999). Conclusion. The postoperative course of children after OLT is associated with multiple complications. In recent years OLT was performed in younger children; living donors were more common; the rate of postoperative infection and suspected rejection was reduced significantly; however patients required longer MV and LOS in the PCCU.

Abstract
Infection after pediatric living donor liver transplantation (LDLT) is a major cause of morbidity and mortality. Here, we sought to determine the incidence, timing, location, and risk factors for bacterial and fungal infections. We retrospectively investigated infection for 3 postoperative months in 345 consecutive pediatric patients (56.2% were females) who underwent primary LDLT at Kyoto University Hospital, Japan. A total of 179 patients (51.9%) developed at least 1 bacterial and/or fungal infection episode, with an infection rate of 2.5 per patient. The predominant infection site was the surgical site (52%). Most of the bacterial and fungal infection occurred within the first month. Enterococcus species followed by multidrug-resistant Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus were the predominant bacterial pathogens. All fungal isolates were Candida species. Prolonged preoperative hospital stay more than 7 days (P = 0.025) and bile leak (P = 0.047) were independent predictors of bacterial infection. Preoperative ascites (P = 0.009) and prolonged insertion of intravascular catheters (P = 0.001) independently predicted fungal infections. Bacterial and fungal infections were responsible for 42.9% of the causes of death in our study. To avoid bacterial and fungal infections after LDLT, broader-spectrum prophylaxis to cover the range of organisms seen in these infections should be considered as a more favorable treatment regimen to prevent prophylaxis failure, especially for patients with a preoperative hospital stay more than 7 days or operative complications in the form of a bile leak. Early drain removal and prophylactic antifungal drugs should be considered for patients with preoperative ascites. Cooperation between attending physicians and infectious disease physicians can improve the outcome of patients after LDLT.

Abstract
It is well documented that ultraviolet (UV) radiation present in sunlight suppresses immune responses. However, the majority of studies documenting the immunosuppressive effects of UV irradiation have been carried out in animals exposed to UV irradiation before immunization. Here, we report that recipient mice exposed to UV irradiation 7 days after immunization with a donor alloantigen exhibited prolongation of allograft survival in an alloantigen-specific manner. Recipient mice (H-2(b)) intravenously immunized with 2 x 10(7) allogeneic spleen cells (H-2(b/d)) 7 days before UV irradiation (40 kJ/m(2)) showed prolonged survival of allografts presenting the alloantigen used for sensitization (H-2(b/d)), but not third-party allografts (H-2(b/k)). Adoptive transfer experiments revealed that CD4(+) T cells in UV-irradiated recipients were responsible for this prolongation. CD4(+) T cells that could transfer the suppression produced large amounts of interleukin (IL)-10, but not IL-4. The effect of UV irradiation on alloantigen-specific immunosuppression was cancelled by administration of an anti-IL-10 monoclonal antibody. These results indicate that UV irradiation given after alloantigen immunization induces alloantigen-specific type 1 regulatory T cell-like regulatory T cells that prolong allograft survival and imply that the difficulties associated with predicting donor-related organ availability in transplantation can be dealt with, given the effectiveness of UV irradiation after immunization.

Abstract
An 11-year-old boy presented with hepatic failure secondary to parvovirus B19 infection, requiring urgent liver transplantation. His recovery was complicated by primary Epstein-Barr virus and cytomegalovirus infections. He subsequently developed aplastic anaemia that has been refractory to antithymocyte globulin and cyclosporine therapy and may now require bone marrow transplantation. We present this case to emphasize parvovirus as a rare cause of hepatic failure and of aplastic anaemia as a complication of the virus.

Abstract
BACKGROUND This study examines the results of liver transplantation (LT) in children 5 kg or less. Reports suggest an increased morbidity and mortality in children weighing 5 kg or less as compared to larger children. However, over half of all children needing LT are <1 year old. Improving outcomes in very small children is a major goal of liver transplantation. METHODS All children under 21 years of age transplanted from January 1990 to June 2005 were included in this study. One hundred sixty-eight primary liver transplants were done: 61 in children less than one year of age and 20 in infants weighing 5 kg or less at LT (2 to 5 kg). These 20 infants underwent 23 transplants. Whole organs were used in 39% of transplants, and reduced or split grafts were used in 61%. Arterial reconstruction using aortic conduits was done in 22%. Analysis included Fischer's exact or Chi square test for non-parametric analysis while patient survival was calculated using the Kaplan-Meier method test with differences in survival assessed using the log rank test. RESULTS Five-year survival for infants 5 kg or less was 74%, and graft survival was 60%, which was not different from patients transplanted that were >5 kg. There were three perioperative deaths, one from primary graft non-function, and two from portal vein thrombosis. There were no bile leaks or hepatic artery thromboses. Bacterial, fungal, and viral infections made up the vast majority of the postoperative complications (65%), with viral infections resulting in two graft losses requiring re-transplantation. Rejection occurred in 25% of patients, of which one required OKT3. Five of the 23 liver transplants in infants less than 5 kg were done prior to 1996, with a five-year graft survival of only 20%. Improvements in technique and postoperative care after 1996 led to improved graft and patient survival of 77% and 86% respectively. CONCLUSIONS Liver transplantation for infants weighing less than 5 kilograms can be technically challenging but can have equivalent graft and patient survival when compared to larger children requiring liver transplantation. Infants should not be denied liver transplantation based on weight alone.

Abstract
Bacterial infections in recipients of bone marrow and solid-organ transplants remain a major cause of morbidity and death. The cases of 42 children who had undergone transplantation and developed an infection with Streptococcus pneumoniae were retrospectively reviewed. Thirty-four patients had 1 episode of infection, whereas 7 had 2 episodes and 1 had 3 episodes of infection. Solid-organ recipients were more likely to have recurrent invasive disease (P<.02). A total of 31 (74%) of 42 patients were on immunosuppressive therapy, and 74% had been on antimicrobial therapy within 30 days before diagnosis of S. pneumoniae infection. Only 33% of eligible patients had received a pneumococcal vaccine. Twenty-six percent of isolates recovered were not susceptible to penicillin, and 18% were not susceptible to ceftriaxone. Two patients experienced infection-related deaths; one of these had a penicillin-nonsusceptible isolate. The antimicrobial susceptibilities and outcome of infections with S. pneumoniae in patients who have undergone transplantation are similar to those in the general pediatric population.

Abstract
We studied, retrospectively, postoperative infectious complications following paediatric liver transplantation at a single university centre. The objectives were to characterize the epidemiology of infection and to determine the associated risk factors during the early postoperative period, either the first postoperative month or the entire duration of paediatric intensive care unit (PICU) stay. Forty-eight liver transplants were performed on 46 patients. Sixty-three infections occurred in 32 patients who underwent 34 liver transplantations (1.36 infection/patient); 47 were bacterial, 6 fungal and 10 viral. The most common sites of infection were bloodstream (36.5%) and abdomen (30%). Gram-positive bacteria (78%) predominated over gram-negative bacteria (22%). Initial analysis revealed infection risk factors to be age <1 year, body weight <10 kg, extrahepatic biliary atresia, intraoperative transfusion > 160 ml x kg(-1), mechanical ventilation > 8 days and PICU stay > 19 days. After stratified analysis, the main risk factor for infection was low body weight of the recipient.

Abstract
A retrospective study was conducted to determine the significance of intensive care management on outcome after liver transplantation (LTx) in children. Of 195 transplants performed in 162 children, factors affecting morbidity and mortality were documented during the post-operative intensive care unit (ICU) stay. To assess the gain in experience of ICU management, we compared mean ventilation time and stay in the ICU as well as mortality, incidence of surgical complications, infections, and rejection episodes, during three different time-periods (October 1991-August 1994, September 1994-July 1996, and August 1996-February 1998). The time spent by patients in the ICU (9.7 days vs. 7.9 days vs. 4.7 days, p < 0.001) and time on ventilation (5.2 days vs. 3.1 days vs. 1.2 days, p < 0.001) were significantly reduced over the duration of the study. The overall mortality was 18.0% (n = 30) and 76.7% (n = 23) of these deaths occurred during the early post-operative period in the ICU. The incidence of severe surgical complications decreased significantly over time, and the application of intra-operative Doppler ultrasound since 1994 led to detection of 27 correctable vascular complications. The overall incidence of acute cellular rejection episodes in our center was 64.1%: 43.5% of the infectious episodes occurred in the ICU (bacterial 70.2%, viral 12.3%, and fungal 17.5%). The main side-effect from immunosuppressive drugs was arterial hypertension in 29% of the patients. We conclude that our efforts to improve intensive care management and monitoring were the key elements in reducing morbidity and mortality after pediatric LTx.

Abstract
STUDY OBJECTIVE To determine those infants at high risk for perioperative complications and mortality following living, related liver transplantation. DESIGN Retrospective chart review. SETTING Large metropolitan teaching hospital. MEASUREMENTS AND MAIN RESULTS The charts and anesthetic records of the 12 infants and children who received the left lateral hepatic segment from a living relative the past 2 years at our institution were reviewed. The records were examined to determine the causes of perioperative morbidity and to identify patients at high risk for serious complications and mortality. All infants and children (mean +/- SD age, 29+/-30 months; weight, 13.6 +/-6.8 kg) survived the operation (8.3+/-1.7 hours) without intraoperative complications. The average blood loss, including 500 mL of recipient blood used to flush the liver before reperfusion, was 1483 +/-873 mL (119+/-70 mL/kg). Three infants developed portal vein thrombosis, and one of these infants also had hepatic artery thrombosis. The risk of vessel thrombosis was significantly higher (3/3 vs. 0/9; p<0.0045) in infants less than 9 kg body weight, as was the risk of death (2/3 vs. 0/9; p<0.045). Both children who died had vascular thrombosis. Other serious complications were bleeding, 6; infection, 7; acute rejection, 3; and bile leak, 2. CONCLUSIONS Infants and children can successfully undergo living, related liver transplantation. However, the risks of vascular complications and death are greater in infants less than 9 kg body weight.

Abstract
Increased survival for young liver transplant recipients has greatly improved. Increasing success has led to broader indications, thereby increasing the number of potential recipients. Pediatric liver centers are developing new strategies to cope with the ever-increasing demands for suitable size appropriate grafts. UNOS is in the process of updating guidelines to regulate the sharing of organs which become available from new surgical techniques. In the future, alternative therapies, such as artificial liver assist devices and techniques of cellular transplantation and genetic modification of hepatocytes, may decrease the number of children who die while waiting for a suitable organ or even obviate the need for the liver transplantation.

Abstract
BACKGROUND The present study analyzes pretransplantation variables associated with long-term liver allograft survival in 278 children who underwent transplantation under primary tacrolimus (FK506) therapy at a single center between October 1989 and October 1996. METHODS The influence of 17 pretransplantation variables on long-term liver allograft outcome was analyzed. Donor variables included age, weight, gender, and cold ischemia time. Recipient variables included age, weight, gender, original liver disease, pretransplantation waiting time, previous abdominal surgery, United Network of Organ Sharing (UNOS) status, ABO blood group, bilirubin level, prothrombin time, ammonia level, creatinine level, and reduced-size/split liver grafts. RESULTS Overall actuarial graft survival was 79.9% at 1 year, 79.1% at 2 years, and 78.3% at 3, 4, and 5 years. Retransplantation rate was 10.8%. Pretransplantation variables with a significant adverse effect on graft survival by univariate analysis were donor age < or = 1 year (P<0.004), donor weight < or = 10 kg (P<0.003), UNOS status I and II (P<0.007), ABO type O, B, and AB (P<0.03), and reduced-size/split liver grafts (P<0.02). Pretransplantation variables significant by multivariate analysis and therefore independent predictors of inferior graft outcome were donor weight '10 kg (relative risk [RR] 2.91, confidence interval [CI] 1.53-5.51); reduced-size/split liver grafts (RR 2.53, CI 1.30-5.64); and UNOS status I (RR 2.22, CI 1.11-4.43). CONCLUSIONS Pediatric liver transplant recipients receiving primary tacrolimus therapy have long-term graft survival rates approaching 80%. UNOS status, donor weight, and the use of reduced-size/split liver grafts are the most important factors affecting survival.

Abstract
OBJECTIVE To analyze a single center's 13-year experience with 569 pediatric orthotopic liver transplants for end-stage liver disease. SUMMARY BACKGROUND DATA Despite advances in medical therapy, liver replacement continues to be the only definitive mode of therapy for children with end-stage liver disease. Innovative surgical techniques and improved immunosuppression have broadened the application of liver replacement for affected children. However, liver transplantation in the child remains challenging because of the scarcity of donor organs, complex surgical technical demands, and the necessity to prevent long-term complications. METHODS The medical records of 440 consecutive patients younger than 18 years of age undergoing orthotopic liver transplantation for end-stage liver disease from March 20, 1984, to November 15, 1997, were reviewed. Results were analyzed using Cox multivariate regression analysis to determine the statistical strength of independent associations between pretransplant covariates and patient and graft survival. Actuarial patient and graft survival rates were determined at 1, 3, 5, and 10 years. The type and incidence of posttransplant complications were determined, as was the quality of long-term allograft function. The median follow-up period was 4.1 years. RESULTS Biliary atresia was the most common cause (50.4%) of endstage liver disease in this patient population. The median recipient age was 2.4 years; 239 patients (54%) were younger than 3 years of age and 1 11 patients (25%) were younger than 1 year of age. There were 471 whole organs, 29 were ex vivo reduced size, 33 were living-related donor, and 36 were in situ split-liver allografts. Three hundred forty-three (78%) patients underwent a single allograft, whereas 97 patients required retransplantation; hepatic artery thrombosis was the most common indication for retransplantation (55 patients). The 1-, 3-, 5-, and 10-year actuarial patient survival rates were 82%, 80%, 78%, and 76%, respectively; allograft survival rates were 68%, 63%, 60%, and 54%. Long-term liver function remains excellent: current median follow-up values for total bilirubin and aspartate aminotransferase were 0.5 mg/dl and 54 IU/L, respectively. Cox multivariate regression analysis demonstrated that pretransplant patient age, the era of transplantation, and the number of allografts performed significantly and independently predicted patient survival rates, whereas allograft type and pretransplant diagnosis did not. CONCLUSIONS Liver transplantation in the pediatric patient is a durable procedure that provides excellent long-term survival. Although there have been overall improvements in patient outcome with increased experience, the effect is most pronounced for patients younger than 1 year of age. Retransplantation, although effective in a meaningful number of patients, continues to carry a progressive decrement in survival with the number of allografts performed. Use of living-related and in situ split-liver allografts has dramatically reduced waiting times for small children and has improved patient survival.

Abstract
BACKGROUND/PURPOSE This study examined the factors present before liver transplantation (LTx) influencing the outcome in 14 patients who had biliary atresia (BA) who underwent LTx. RESULTS Nine patients survived (Group A), whereas five died primarily of infection (Group B). Rate of the attempted multiple hepatic portoenterostomy (HPE) and existence of intestinal stoma was significantly higher in Group B than in Group A. Pre-LTx parameters showed significant difference between the two groups as follows: total bilirubin, 15.9 +/- 7.9 versus 29.1 +/- 14.5 mg/dL (P = .0446); gamma-glutamyl transpeptidase, 170.0 +/- 97.6 versus 65.2 +/- 38.8 IU/L (P = .0425); the body weight deviation score, 0.17 +/- 0.88 SD versus -1.46 +/- 0.30 SD (P = .0029); total cholesterol, 129.4 +/- 33.5 versus 52.2 +/- 20.4 mg/dL (P = .0008) in Group A versus Group B. Total cholesterol level and body weight for age remained within normal range until the advanced stage and rapidly decreased according to deterioration of the general condition before LTx. CONCLUSIONS From these results, avoidance of multiple HPE and closure of stoma before LTx may be preferable. LTx should be performed before failure to thrive or hypocholesterolemia develops.

Abstract
A bile duct stricture caused by an inadvertent ligation or suture during donor operation is rare, but not a negligible complication after living-related liver transplantation (LRLT). We present here a simple technique to prevent this kind of complication. Before bilioenteric anastomosis, a rod-shaped surgical probe was introduced into the bile ducts of the graft to examine their patency. The position of the surgical probe and the liver segment in which the probe proceeded was checked using ultrasonography. Using this technique in all of our 60 cases of LRLT, we have had no experience of this bile duct complication. We recommend this technique to be adopted in LRLT and split-liver transplantation to diminish the risk of biliary complications.

Abstract
The technical and medical management of small infants requiring orthotopic liver transplantation remains a challenge. The present study examined 117 orthotopic liver transplantations performed in 101 infants from <1 to 23 months of age between March 1988 and February 1995 to determine factors that influence patient and graft outcome. Factors analyzed included etiology of liver disease, recipient and donor age and weight, United Network for Organ Sharing (UNOS) status, retransplantation, ABO-compatibility, full-size (FS) versus reduced-size grafts, vascular thrombosis (VT), including hepatic artery and portal vein (PVT), and the presence of lymphoproliferative disease (LPD). UNOS status 1, fulminant hepatic failure, and the development of Epstein-Barr virus-associated LPD were each associated with 10-20% lower patient and graft survival rates. Of 101 infants, 11 (11%) developed LPD with an associated 36% mortality. VT occurred in 10 (9 hepatic artery and 1 portal vein) of 117 orthotopic liver transplantations (9%), all less than 1 year of age, and was associated with significantly poorer 1-year (50% vs. 85% no VT, P<0.01) and 5-year patient survival rates (50% vs. 83% no VT, P<0.01). One-year graft survival rates for FS grafts in recipients <12 months versus 12-23 months were 67% vs. 94% (P<0.01); the patient survival rate was also significantly lower in FS graft recipients <12 months (76% vs. 100%, P<0.05). Recipients <5 months of age had the worst survival rates: 1-year and 5-year patient survival rates were 65% and 46% for recipients 0-4 months (n=17) versus 82% and 82% for recipients 5-11 months (n=56), and 93% and 93% for recipients age 12-23 months (n=28; P<0.05). In summary, factors associated with reduced survival rates include recipient age <5 months, recipient age <12 months who received FS grafts, development of VT and donor weight <6 kg. There was a trend for UNOS status 1, fulminant hepatic failure, and presence of LPD to be associated with reduced survival rates.

Abstract
Infections due to Nocardia transvalensis are extremely rare: only four disseminated infections with this pathogen have been reported, three of which ended fatally. This is the first report of a liver transplant recipient with Nocardia transvalensis infection. The patient had disseminated infection with pulmonary involvement, which presented as pulmonary infarction. Despite a ten-day delay in the administration of correct therapy, he responded rapidly to trimethoprim-sulfamethoxazole. The pitfalls of differentiating nocardial infection from pulmonary thromboembolism in solid organ transplant recipients and the diagnostic considerations unique to liver transplant recipients are discussed.

Abstract
We reviewed 37 living related liver transplantations (LRLT) performed by our department during the last 27 months on children with end-stage liver disease. The patients were 15 boys and 22 girls aged 7 months to 15 years with biliary atresia (27), cryptogenic cirrhosis (3), Budd-Chiari syndrome (2), progressive intrahepatic cholestasis (2), protoporphyria (1), Wilson's disease (1), and fulminant hepatitis (1). The donors were 14 fathers and 23 mothers. Grafts were made from the left lateral segment (19), left lateral segment with partial S4 (11), left lobe (6), and right lobe (1). After graft harvesting all donors resumed normal liver function and normal life. The recipient underwent total hepatectomy with preservation of the inferior vena cava. FK506 and low-dose steroids were used for immunosuppression. The survival rate was 90% (27/30) in elective cases and 57% (4/7) in emergency cases. Six recipients had functioning grafts but died of extrahepatic complications. Hepatic vein stenosis occurred in 3 cases at 3 months after LRLT and was successfully treated by balloon dilatation. Portal vein stenosis occurred in 1 case at 8 months after LRLT and was also safely dilated. We incurred no hepatic artery thrombosis after introducing microsurgery techniques. Among 12 viral, 5 bacterial, and 3 fungal postoperative infections, 1 Candida pneumonia and 1 EBV-associated lymphoma were lethal. Three patients with ABO-blood group compatible grafts and one with an incompatible graft developed acute rejection, which was controlled in evey case by steroid bolus and/or increasing the dose of FK506. There were no definite episodes of rejection in ABO-identical cases. Children with moderate growth retardation (> or = -1.5 SD of normal growth) caught up in growth soon after LRLT, but those with severe retardation (<-1.5 SD) were slow to attain age-normal height. Appropriate timing, meticulous surgical procedures, and comprehensive management of complications are crucial for successful outcome with LRLT. LRLT is a promising option for alleviating the shortage of livers for pediatric transplantation and may be regarded as an independent modality to supplement cadaver donation.

Abstract
During the last 31 months, 50 children between 3 months and 15 years of age have undergone living related liver transplantation (LRLT) for end-stage liver diseases (39 biliary atresia, 2 Budd-Chiari syndrome, 2 progressive intrahepatic cholestasis, 3 liver cirrhosis, 1 Wilson disease, 1 protoporphyria, 1 tyrosinemia, and 1 fulminant hepatitis). Combined FK-506 and low-dose steroids were routinely used for immunosuppression. There were seven deaths, two of which were related to infection (Candida pneumonia and Epstein-Barr virus [EBV]-associated lymphoproliferative syndrome [LPS]). Five patients had a bacterial infection, all of which were associated with surgical complications. Three patients had Candida infection, all of which were malnourished, had biliary atresia, and had been managed with prolonged antibiotics against obstinate ascending cholangitis. There were 14 symptomatic viral infections (1 herpes simplex virus, 1 herpes zoster virus, 5 cytomegalovirus [CMV], 6 EBV, and 1 EBV-associated LPS). Three of the five CMV infections appeared in patients whose graft was ABO-incompatible, who were managed with prophylactic OKT-3. Most of the viral infections (except 1 EBV-associated LPS) were minor and were treated successfully. The low incidence and successful treatment of CMV infection are related to the high compatibility and low incidence of allograft rejection in LRLT. Bacterial and fungal infections can be decreased by greater refinement of surgical technique and more aggressive preoperative management. Treatment of EBV infection is still an unsolved problem.

Abstract
Biliary tract complications are reported in 15% to 30% of orthotopic liver transplantations (OLTs). Since 1986, 53 OLTs were done in 48 children with a mean age and weight of 5.3 years and 18.9 kg, respectively. Twenty-seven transplantations (51%) were reduced liver grafts (RLG) and 26 (49%) were whole liver grafts (WLG). Since 1988, 70% of transplantations have been RLG. Choledochocholedochostomy (mean weight, 25 kg) with a T-tube (CC) or choledochojejunostomy (CJ) (mean weight, 14.5 kg) were done in 24 (45%) and 29 (55%) cases, respectively. The overall mortality was 19% but none of the deaths were related to biliary problems. There were 13 biliary tract complications (24.5%) in 11 patients including 7 leaks, 5 obstructions, and 1 intrahepatic biloma. Leaks leading to bile peritonitis were managed with simple suture and drainage and were related to the T-tube (4), to the Roux-en-Y loop (2), and to the transection margin of a RLG (1). Obstruction was documented in 5 cases with none associated with hepatic artery thrombosis (HAT). Stenosis after CC reconstruction (2) required conversion to CJ. Two patients had revision of CJ because of kinking of the common bile duct after a left lateral segment graft and an anastomotic stricture 46 months after OLT. The last patient developed a vanishing bile duct syndrome 4 months posttransplant and is awaiting retransplantation. One patient had multiple episodes of cholangitis after HAT and was retransplanted. Neither the type of grafts (RLG 25.9% v WLG 23.1%) nor the type of biliary reconstruction (CC 25% v CJ 24%) influenced the rate of biliary complications.(ABSTRACT TRUNCATED AT 250 WORDS)
