ABSTRACT

AIM: The issue of performing an anastomosis of the anterior sector veins to the vena cava in living donor liver transplantation is still controversial. We aimed to research whether there was any difference in terms of complications, rejections, and graft survival between patients with and without anterior sector venous drainage to the vena cava. PATIENTS AND METHODS: Patients were retrospectively investigated for demographic data and ratio of graft needed to available graft weight. Donors had volumetric calculations and middle hepatic vein anterior sector drainage documented in detail. RESULTS: Seventy-three donors with middle hepatic vein drainage were included. Thirty-five had anterior sector venous drainage performed and 38 patients did not have drainage procedures performed. The incidence of general complications was higher in the group without anterior sector drainage (78.3% and P = .002). Biloma linked to bile leaks were observed in 8 patients without drainage (72.8%) and 3 patients with drainage (27.2%). Late acute rejection occurring during follow up after transplantation was identified in 28 patients (11.6%). Of these, 1 (14.3%) had anterior sector drainage and 6 (85.7%) were in the patient group without drainage (P = .067). CONCLUSION: As a result of this study, for patients with grafts at the volume limit (graft weight to receiver weight ratio <0.8) and with congestion observed in the anterior sector after liver implantation and for patients with outflow problems identified on Doppler ultrasonography, anterior sector veins >5 mm should definitely be drained into the vena cava. Hence, both complication and rejection rates will reduce, and we can lengthen the graft, and thus patient, survival.

ABSTRACT

AIM: Liver transplantation (LT) is the most promising treatment method in hepatocellular cancer (HCC). Due to the shortage of organ donors and the possible risks associated with living donation, the selection of patients for LT is critical. The aim of this study is to investigate the predictive ability of the Glasgow Prognostic Score (GPS), modified GPS (mGPS), and hepatic GPS (hGPS) on prognoses in a patient group who underwent deceased donor LT (DDLT) or living-donor LT (LDLT) for HCC. PATIENTS AND METHODS: This study includes 62 DDLT and 55 LDLT patients who underwent LT for HCC between 1998 and 2016 in a single center. The study endpoints were recurrence, 0- to 1-year mortality, 0- to 3-year mortality, mortality, and overall survival (OS). RESULTS: The median follow-up time was 70.24 ± 48.47 months. GPS and hGPS positivity were found to be prognostic indicators of 0- to 3-year mortality and overall mortality in DDLT (P = .012, P = .006; P = .044 and P = .022 respectively). In the LDLT group, GPS was found to be effective in predicting 0- to 1-year and 0- to 3-year mortality (P = .045, P = .022 respectively); GPS and hGPS were also found to be effective in predicting overall mortality (P = .001 and P = .046 respectively). The OS was significantly longer in the GPS 0 group and hGPS 0 group compared to the GPS 1-2 and hGPS 1-2 group in both DDLT and LDLT. CONCLUSION: The findings of this study and the literature indicate that using GPS and hGPS is appropriate in selecting patients with HCC who are candidates for LT.

ABSTRACT

AIM: This study aims to evaluate survival rates in elderly patients after liver transplantation (LT) and to analyze the factors associated with mortality. PATIENTS AND METHODS: Our study includes 535 patients over the age of 18 who had undergone LT in our clinic between June 2004 and January 2018. Data were collected prospectively and scanned retrospectively. Data concerning the patients' age, sex, LT indication, Child-Turcotte-Pugh score, Model for End-Stage Liver Disease score, presence of hepatocellular cancer (HCC), coexisting disease, LT types, and post-transplant survival were investigated. The patients were grouped under 2 categories (18-59 years of age and 60 years of age and over) and were compared in terms of their characteristics. In patients aged 60 and over, the causes of mortality and related factors were investigated. RESULTS: The study included 535 patients, 458 (85.6%) of whom were between 18 and 59 years of age and 77 (14.4%) were over 60 years of age. The median follow-up period was 86.7 (1 to 247) months. The elderly group's survival rate was significantly lower than that of the younger group (P = .002). In elderly patients, survival rates of 1, 3, 5, and 10 years were 67.4%, 56.4%, 53.8%, and 46.1%, respectively. CONCLUSION: In elderly patients, factors that increase post-LT mortality require thorough consideration. Equally important is the physiological status of the candidates for transplantation. Correct patient selection in the preoperative stage and good postoperative care can provide successful survival results in elderly patients.

ABSTRACT

AIM: Small-for-size grafts have become more important, especially in living donor liver transplants. The Pringle maneuver, used to reduce blood loss, and the immunosuppressive medications used to prevent graft rejection in liver transplants have different side effects on liver regeneration. We researched the effect of situations where tacrolimus and the Pringle maneuver were applied or not on liver regeneration in rats with partial hepatectomy. MATERIAL AND METHODS: This study was completed with 35 Wistar Albino rats. The subjects were randomly divided into 5 groups: Group 1 had the abdomen opened and no other procedure was performed; Group 2 underwent a 70% hepatectomy; Group 3 underwent a 15-minute Pringle maneuver + 70% hepatectomy; Group 4 underwent a 70% hepatectomy + 5 days of 1 mg/kg/day intraperitoneal tacrolimus; and Group 5 underwent a 150 minute Pringle maneuver + 0% hepatectomy + 5 days of 1 mg/kg/day intraperitoneal tacrolimus. All rats were sacrificed on the seventh postoperative day, remaining liver tissue was weighed, and weight indices created. The remaining liver tissue was stained with phosphohistone H3 and the mitotic index calculated. RESULTS: The groups that underwent the Pringle maneuver, 70% hepatectomy, and tacrolimus administration were compared with the control group in terms of mitotic index and weight index, but no statistically significant differences were identified. CONCLUSION: Suppression of regeneration forms a risk after liver transplantation with small-volume grafts. As a result, research on the effect of tacrolimus combined with the Pringle maneuver is important, especially for transplantations using segmented liver grafts. In our study, we showed that the use of tacrolimus had no negative effect on liver regeneration.

ABSTRACT

AIM: There is a well-known risk of the emergence of hepatic failure in living donor transplant cases on whom are performed a right donor hepatectomy (RDH). There are different prevalence ratios in literature on this phenomenon. In our study, we aim to depict the prevalence of hepatic failure and risk factors in our cases regarding the most recent description criteria related to hepatic failure. PATIENTS AND METHODS: We included right liver donor hepatectomy cases who fit the donor evaluation algorithm at the Dokuz Eylul University Liver Transplantation Unit between the period of June 2000 and September 2017. The patients were evaluated regarding preoperative data. Liver failure was defined according to the International Study Group of Liver Surgery (ISGLS) criteria. We also included statistical analysis of risk factors that are potentially related to liver failure. RESULTS: We included a total of 276 patients. In 27 (9.7%) patients, we observed posthepatectomy liver failure (PHLF). In 26 (9.4%) patients, we observed Grade A liver failure; in 1 (0.3%) patient, we observed Grade B liver failure. We did not observe any Grade C hepatic failure. In patients with hepatic failure, we observed a significantly longer period of hospitalization (P = .007). Old age (odds ratio = 1.065, 95% confidence interval, 1.135-29.108, P = .035) and preoperatory red blood cell (RBC) transfusion (odds ratio = 5.749, 95% confidence interval, 1.019-1.113, P = .005) were shown as independent risk factors for PHLF. CONCLUSION: Posthepatectomy liver failure is a vital complication of RDH. The risk can be decreased by careful selection of donor candidates. Elderly donor candidates and intraoperative RBC are independent risk factors for PHLF.

ABSTRACT

INTRODUCTION: Because of the shortage of organs available for transplantation, living related sequential transplantation with the use of liver and a kidney from the same donor has emerged as a reasonable therapeutic alternative. However, there is insufficient literature about the complications that living donors experience after simultaneous kidney and liver transplantations. METHODS: From December 2001 to October 2009, 5 living donors provided simultaneous donation of livers and kidneys and 1 living donor donated first her kidney and then her liver. Demographic data of the donors and information concerning the surgery and postoperative observation were collected prospectively. RESULTS: All of the donors were female. The median age was 27.5 (range, 19-36) years. Indications requiring the simultaneous transplantation of livers and kidneys were primary hyperoxaluria type 1 (PH1) in 5 potential recipients and cirrhosis due to chronic hepatitis B infection and idiopathic chronic renal insufficiency in 1 potential recipient. Four recipients underwent right hepatectomy (segments 5-8) and right nephrectomy; 1 recipient underwent left hepatectomy (segments 2-4) and right nephrectomy; and 1 recipient underwent left lobectomy (segments 2-3) and right nephrectomy. There were no complications except in 1 donor (postoperative ileus). No donor developed hypertension or microalbuminuria. CONCLUSIONS: With the right indications, appropriate preoperative evaluation, meticulous surgical technique, proper postoperative care, and long-term close monitoring to minimize morbidity and mortality risks, liver and kidney donation from the same donor can be considered for simultaneous kidney and liver transplantation.

ABSTRACT

INTRODUCTION: We investigated the liver transplantation literature since 1975 and found the most frequently cited 100 articles and assessed the distribution of authors and journals of these articles. METHOD: Using the advanced mode of the Institute for Scientific Information (ISI) Web of Science (WOS) search engine, the words "SU = transplantation AND TI = liver OR SU = transplantation AND TS = liver" were used to scan articles and determine the most-cited 100 articles on July 18, 2016. RESULTS: From 1975 to date, it appears a total of 43,369 articles were published in the field of liver transplantation in the WOS. Although the most cited article had 677 citations, the least cited article had 180 citations. The mean citation number for the 100 articles was 252.31 ± 96.75. The mean annual citation number for the articles varied from 61.55 to 5 and the mean was 15.31 ± 8.63. The most cited article was by Feng et al "Characteristics Associated With Liver Graft Failure: The Concept of a Donor Risk Index" published in the American Journal of Transplantation (677 citations). CONCLUSION: Bibliometric analysis highlights the key topics and publications that have shaped the understanding and management of liver transplantation. According to our research, this is the first study to investigate articles with most citations in the field of liver transplantation. In our study the article with the most citations was cited 677 times, whereas the 100th article was cited 180 times with a mean citation number for the 100 articles of 252.31 ± 96.75.

ABSTRACT

INTRODUCTION: In living donor liver transplantation (LDLT), hepatic arterial continuity is crucial to avoid biliary leakage, biliary stricture, cholangitis, and graft and patient loss. Sometimes there exist factors making anastomosis difficult or even impossible. In these cases, a vascular graft may be needed to bridge the two arteries for revascularization. METHOD: Medical records of 297 patients who underwent LDLT between June 2000 and July 2016 at the Hepatopancreatobiliary Surgery and Liver Transplantation Unit of Dokuz Eylul University Hospital were reviewed retrospectively. Twenty-eight (9%) patients younger than the age of 18 were excluded from the study. The remaining 269 patients were included in the study. We analyzed data of patients who developed hepatic arterial complications during or after LDLT and underwent revascularization using autologous interposed inferior mesenteric artery (IMA) grafts. RESULTS: In 8 (2.9%) of the 269 patients who underwent LDLT and were included in the study, autologous interposed IMA grafts were used for the hepatic artery revascularization. All of the patients were males. Their mean age was 42 (range, 25-57). The mean duration of follow-up was 83.25 months (range, 3-144 months). One patient developed intraoperative hepatic arterial thrombosis (HAT) after autologus IMA reconstruction and this patient needed retransplantation. No arterial complications developed in the other 7 patients. CONCLUSION: Autologous interposed IMA graft could be used as an alternative vascular graft in hepatic artery revascularization to provide tension-free hepatic arterial continuity.

ABSTRACT

INTRODUCTION: Living donor liver transplantation (LDLT) is performed with increasing frequency worldwide due to the shortage of donated organs. It is a life-saving procedure for the recipient, but, on the other hand, a major surgical procedure for healthy donors and it may cause morbidity and even mortality. PATIENTS AND METHODS: This research was completed at Dokuz Eylül University Faculty of Medicine Hospital General Surgery Department Liver Transplant Unit and included 280 cases (4 with simultaneous liver and kidney transplants from living donors) who underwent donor right hepatectomy for LDLT from June 2000 to June 2016. We analyzed the data of patients retrospectively. RESULTS: Of 280 donor right hepatectomies for LDLT, 181 were male (M; 64.6%) and 99 were female (F; 35.4%) (M/F: 1.82). Mean donor age was 31.2 ± 0.9 years (range, 18-56). Mean donor monitoring duration was 45 ± 2.4 months (range, 3-192 months). Mean body mass index (BMI) was 24.28 ± 2.96 kg/m2 (range, 18.1-32.42 kg/m2). In our study 72 cases (25.7%) developed postoperative complications. There were 17 Clavien grade 3A, 1 grade 3B, and 5 grade 4A complications and also 1 death due to pulmonary embolism. CONCLUSION: Together with the increase in living donor surgery, the morbidity and mortality of these cases are becoming controversial. Full donor safety is only possible with appropriate donor choice requiring very detailed studies, a problem-free hepatectomy process, and close postoperative donor monitoring.

ABSTRACT

Liver transplantation is increasing worldwide. Pregnancy after liver transplantation is considered to be well tolerated with favorable neonatal outcomes in cases of stable and sufficient graft function. In this study, our aim was to determine pregnancy and neonatal outcomes of patients after liver transplantation. Data for patients who had been followed-up by the liver transplantation clinic at the Dokuz Eylül University Medical Faculty Hospital, Turkey, between 2002 and 2016, and who had pregnancy after the transplantation were evaluated retrospectively. The earliest post-transplantation conception occurred after 22 months and the latest conception occurred after 108 months (mean, 55.4 months). Twenty-one pregnancies concluded with live births (100%). The mean birth week was 37.09. The earliest birth occurred at 27 weeks and the latest at 40 weeks. Mean birth weight was 2993 g (10th to 25th percentiles). No pregnancy-induced hypertension, pre-eclampsia, or gestational diabetes were observed in any patient. Five pregnancies concluded with premature birth. In conclusion, several complications may occur during pregnancy (such as hypertension or pre-eclampsia, etc) in patients with liver transplantation, but it seems that pregnancy has good effects on graft functions and the neonatal outcomes are favorable.

ABSTRACT

BACKGROUND: The aim of this study was to determine the incidence and peri-operative risk factors for acute renal injury (ARI) and their relationship with mortality rate through the use of 3 different ARI diagnostic classifications in patients after liver transplantation (LT). METHODS: We retrospectively investigated the medical records of adult LT recipients. Post-operative ARI was determined with the Risk, Injury, Failure, Loss, and End-Stage Renal Failure (RIFLE), Acute Kidney Injury Network (AKIN), and Kidney Disease: Improving Global Outcomes (KDIGO) classifications. RESULTS: We analyzed 440 adult patients. The post-operative incidence of ARI was 8.0% by the RIFLE classification, 14.31% by the AKIN classification, and 14.54% by the KDIGO classification. Significant risk factors for ARI were pre-operative albumin (odds ratio [OR], 0.776; 95% confidence interval [CI], 0.473-1.273 for AKIN; and OR, 0.724; 95% CI, 0.444-1.182 for KDIGO) and hemoglobin levels (OR, 2.830; 95% CI, 1.157-6.9261 by RIFLE), intra-operative red blood cell transfusion (OR, 1.072; 95% CI, 1.004-1.143 by AKIN; and OR, 1.077; 95% CI, 1.011-1.147 by KDIGO), and blood loss (OR, 1.00; 95% CI, 0.999-1.000 by RIFLE). The early mortality rate was 7.9% in our series. CONCLUSIONS: The RIFLE, AKIN, and KDIGO ARI classifications classify the severity of renal dysfunction in patients who have undergone LT. Direct associations were found between higher mortality rates and severity of renal disease.

ABSTRACT

INTRODUCTION: Late acute rejection (LAR) is a clinical manifestation that occurs 6 months after liver transplantation, shows histopathologic features different from those of acute rejection, and is the cause of a high prevalence of morbidity and mortality. METHODS: In this study, hospital records of 211 living donor liver transplantation (LDLT) patients who underwent surgery in our clinic between June 2000 and February 2014 were reviewed retrospectively. The patients were ≥ 18 years old and were followed for ≥ 6 months. RESULTS: Of the 211 patients, 21 (9.9%; 16 males, 5 females) developed LAR. The mean age of the patients was 46 years (range, 33-58). The mean follow-up period was 61.2 months (range, 6-152) and the median time to development of LAR was 26.4 months (range, 7-77). In our study, patients who received cyclosporine and mycophenolate mofetil (MMF) treatment developed more LAR than did patients who received tacrolimus and MMF therapy (P = .05). In addition, the incidence of LAR in patients who underwent LDLT was significantly greater in the ABO-matched groups than in the ABO identical group (P = .028). CONCLUSIONS: Development of LAR and serious complications related to it can be avoided if liver transplant recipients are followed regularly and closely in outpatient clinics after transplantation.

ABSTRACT

BACKGROUND: The aim of this study was to identify acute renal injury (ARI) through the use of RIFLE (risk, injury, failure, loss, end-stage kidney disease) criteria and to investigate perioperative risk factors for ARI in liver transplantation (LT). METHODS: We reviewed medical records of adult LT patients retrospectively. Postoperative ARI was staged with RIFLE criteria by the 1st and 7th days of the surgery. RESULTS: We analyzed 440 adult LT patients, categorized as risk (R), injury (I), or failure (F) according to the RIFLE criteria. In this study, in the first postoperative day, incidence of ARI was 7.95%; all of them were R-class, and, on the 7th day, the incidence of ARI was 7.27%, as R-class 6.59% and I-class 0.68%. Significant risk factors were detected within the first postoperative day including pre-operative hemoglobin levels <9 g/dL (P = .019), intra-operative transfusion of red blood cells (RBCs) (P = .049) and fresh-frozen plasma (FFP) (P = .049), blood loss (P = .011), and post-reperfusion syndrome (P = .023). Multivariate analysis revealed risk factors for ARI as RBCs (odds ratio [OR], 1.049; P = .247) and FFP (OR, 1.017; P = .627) transfusion and blood loss (OR, 1.000; P = .021) (blood loss OR: 0.9996952300184; 95% confidence interval: 0.9994356774026 to 0.999548500399). The only significant risk factor for the 7th postoperative day was the Model for End-Stage Liver Disease (MELD) score (>20) (P = .002). CONCLUSIONS: This study showed that RBC and FFP transfusion, perioperative blood loss, and MELD score >20 are risk factors for LT-related ARI. Also normalization of hemoglobin levels with non-blood products in patients with preoperative low hemoglobin levels can diminish the need for RBC and that can prevent ARI.

ABSTRACT

OBJECTIVE: Surgical site infection (SSI) is the most common infection after liver transplantation in our hospital. In this study, the effect of microorganisms isolated in liver transplant recipients' (LTRs') culture with SSI on antibiotic treatment has been investigated. METHOD: Between January 2003 and December 2013, microbiological data and antibiotic management of LTRs were examined from laboratory and patients' records retrospectively. For diagnosis of SSI, the Centers for Disease Control and Prevention criteria were used. Infections have been classified into 3 groups according to agent existence (culture negative, monomicrobial, or polymicrobial). The data were analyzed with the SPSS 17 program. RESULTS: In the study period, 457 liver transplantations were performed. The study included 412 adult LTRs. In 122 (29.6%) of these patients, at least 1 infection was detected within 30 days after transplantation. Seventy-one (17.2%) were SSI. Of LTRs with SSI, there were 36 (50.7%) with blood stream infection, 16 (22.5%) with pneumonia, and 10 (14.0%) with urinary tract infection together. Eighteen (25.4%) cases were polymicrobial (especially Acinetobacter baumannii and Enterococcus species), 35 (49.2%) cases were monomicrobial (firstly methicilline resistant Staphylococcus aureus), and 18 (25.4%) cases were culture negative SSI. In 60 (84%) cases, combined antibiotic treatment was used. Mortality rate was 14.0%. CONCLUSION: In LTRs with SSI, the impact of the isolation of an infectious agent on antibiotic selection could not be determined. Whether or not there are bacteria, on the basis of the local epidemiological data and patient characteristics, at least 2 or more antibiotics were combined for treatment. According to the resistance of the isolated microorganisms prior antibiotics have been changed.

ABSTRACT

OBJECTIVE: Our aim was to determine perioperative risk factors for early bacterial infection after liver transplantation. METHODS: Retrospectively examining medical records using Centers for Disease Control and Prevention (CDC) definitions to identify nosocomial infections, we analyzed data on 367 adult patients. RESULTS: The incidence of infection was 37.3% (n = 137): namely, surgical site (n = 74; 20.2%) [corrected], blood stream (n = 64; 17.4%), pulmonary (n = 49; 13.4%), urinary system (n = 26; 7.1%). Significant risk factors within the first 30 days were as follows: deceased donor, Model for End-Stage Liver Disease (MELD) >20, albumin level <2.8 g/dL, intraoperative erythrocyte transfusion >6 U, intraoperative fresh frozen plasma >12 U, bilioenteric anastomosis, postoperative intensive care unit stay >6 days, and postoperative length of stay >21 days. Significant risk factors detected within the first 90 days were as follows: MELD >20, preoperative length of stay >7 days, reoperation, postoperative length of intensive care unit stay >6 days, and postoperative length of stay >21 days. Variability was observed in risk factors according to localization of infection. As a result, except for MELD, type of donor, and biliary anastomosis, the others are preventable factors for early bacterial infection. In addition, the same risk factors showed variability according to the site of infection.

ABSTRACT

The study sought to determine the costs of liver transplantation in Turkey. All costs except physician charges were retrospectively investigated in the period from hospitalization to discharge. Liver transplantation was performed in 326 patients between 1999 and 2009. After exclusion of patients whose records could not be accessed (n=5), who underwent second transplantations in the same hospitalization (n=3) or who died before discharge (n=39), 279 patients were eligible for the study. The mean cost of liver transplantation was 30.823 dollars. The mean cost in 2008 was significantly higher than for all other years; thereafter it decreased. Costs were shown to be higher among patients with model for end-stage liver disease (MELD) scores>15. Although there was no significant cost difference among United Network for Organ Sharing (UNOS) groups, the mean costs of subjects of the B group were significantly lower than those of the Child C subjects C (P=.01). When we evaluated the relationship between etiological groups and costs the highest expenses were noted among hepatitis B virus (HBV) and hepato cellular carcinoma (HCC) patients with 75% HBV-positivity together. There was no significant difference between age, gender, and body mass index (BMI) of recipients. The costs did not significantly change with the presence of diabetes mellitus (DM) or portal vein thrombosis before transplantation or antibiotic use after transplantation. Although there was no difference between donor age and costs, living donor transplantation showed significantly higher costs than cadaveric donor cases (P=.01). In conclusion, liver transplantation is an effective treatment in end-stage liver diseases with high cost, albeit in Turkey it is relatively lower than other countries.

ABSTRACT

Living donor liver transplantation has become an alternative therapy for patients with end-stage liver disease. Donors are healthy individuals and donor safety is the primary concern. The objective of this study was to evaluate the anesthetic complications and outcomes for our donor cases; we report one death. The charts of the patients who underwent donor hepatectomy from February 1997 to June 2007 were retrospectively reviewed. Right hepatectomy (resection of segments 5-8) was done in 101 donors, left lobectomy (resection of segments 2-3) in 11 donors, and left hepatectomy (resection of segments 2-4) in one donor. Minor anesthetic complications were shoulder pain, pruritus and urinary retention related to epidural morphine, and major morbidity included central venous catheter-induced thrombosis of the brachial and subclavian vein, neuropraxia, foot drop and prolonged postdural puncture headache. One of 113 donors died from pulmonary embolism on the 11th postoperative day. This procedure has some major risks related to anesthesia and surgery. Although careful attention will lower complication rate, we have to keep in mind that the risks of donor surgery will not be completely eliminated.

ABSTRACT

INTRODUCTION: Primary hyperoxaluria type-1 (PH1) is an autosomal recessive disorder caused by impaired activity of the hepatic peroxisomal alanine-glyoxilate aminotransferase, which leads to end-stage renal disease (ESRD) and requires combined liver-kidney transplantation (CLKT). Herein, we have reported 3 children diagnosed with PH1 who received CLKT. CASE 1: A 4.5-year-old boy with an elder brother diagnosed with PH1 was diagnosed during family screening when the sonography showed multiple calculi. Within 5 years he experienced flank pain, hematuria attacks, and anuric phases due to obstruction and received hemodialysis (HD) when ESRD appeared. CLKT was performed from his full-match sister at the age of 9.5. He is doing well at 5.5 years. CASE 2: A 7-year-old boy was admitted with polyuria, polydypsia, and stomach pain with renal stones on sonography. PD was instituted when serum creatinine and BUN levels were measured as high values. At the age of 10, CKLT was performed from his mother. His liver and renal function tests are well at 14 months after CKLT. CASE 3: A 2.5-year-old girl had attacks of dark urine without any pain; renal stones were imaged on sonography. She was diagnosed with PH1 and operated on several times due to obstruction. She received peritoneal dialysis and a cadaveric CLKT was performed when she was 9 years old. At the age of 16, she experienced chronic allograft nephropathy requiring HD and subsequent cadaveric donor renal transplantation at 1.5 years after initiation of HD. CONCLUSION: Herein, we have presented the favorable clinical outcomes of patients with CKLT to indicate the validity of this treatment choice for PH1.

ABSTRACT

BACKGROUND: Without including the middle hepatic vein (MHV) into right-lobe grafts, venous drainage of the anterior segment (AS) has always been a concern. The efficacy and the necessity of additional venous reconstruction in the AS for graft viability and function are still controversial. METHODS: Since February 2002, 57 right-lobe grafts were implanted into adult recipients. The mean graft to ideal recipient weight ratio (GRWR) was 1.3% (minimum: 0.8%, maximum 2.1%). All minor venous tributaries to the MHV less than 5 mm in diameter were ligated. The management of MHV tributaries was categorized into three groups: (A) no major tributaries (n = 33); (B) major tributaries ligated (n = 11); and (C) major tributaries reconstructed (n = 13). Reconstructions were established using vascular grafts (PTF, n = 8; cadaveric, n = 2) or joining with right hepatic vein orifice (n = 6). The groups were homogenous in age, gender, MELD (17 +/- 6, 16 +/- 4, 18 +/- 7), graft weight (817 +/- 181, 838 +/- 152, and 855 +/- 159 g), and graft/ideal liver weight ratio (0.54 +/- 0.12, 0.57 +/- 0.13, and 0.57 +/- 0.1, respectively). We investigated the volume of ascites, serum bilirubin, albumin, and liver enzyme levels and INR on postoperative day 4 (POD4) and POD21. RESULTS: Two patients died of MRSA sepsis on POD18 and POD23 (MELD: 24 and 28) after initial graft function. Their graft weights were 800 g and 980 g, and their volumes were 47% (group B) and 62% (group A) of the ideal liver mass of the recipients, respectively. One PTF and another cadaveric vascular graft were found occluded 4 and 7 days after implantation without any negative consequence. At 6-month follow-up, the remaining 55 patients were alive with primary liver grafts. Vascular reconstructions were patent except for 2 early occlusions. Among the 3 groups, no significant difference was found on POD4. Three weeks after transplantation, the mean AST level in the major ligation group (46.7 +/- 8.14) was significantly higher than in the minor ligatation group (29.6 +/- 8.6) but not in the major reconstruction group (33.7 +/- 3.7; P = .03 and P = .29). The mean albumin level was highest after minor ligation (3.2 +/- 0.18), which was significantly better than the major reconstruction (2.7 +/- 0.1) but not the major ligation (3.1 +/- 0.14) cohorts (P = .02 and P = .13). CONCLUSIONS: In this study of a limited number of cases, right-lobe liver grafts with GRWR of > or =1.1% displayed optimal graft function without additional venous reconstruction to the AS.

ABSTRACT

The combination of hepatitis B immunoglobulin (HBIG) and antivirals (nucleos[t]ide analogs) has extended the applicability of orthotopic liver transplantation (OLT) for patients with hepatitis B virus (HBV)-related liver disease. However, HBIG administrations have an extremely high cost. Herein, we evaluated our results with low-dose, on-demand, intramuscular HBIG plus lamivudine (LAM) prophylaxis after OLT. The HBV DNA status in 40 patients at the time of OLT determined the treatment: group A (n = 22), HBV DNA (-), no antiviral pretreatment; group B (n = 11), HBV DNA (-), after LAM; group C (n = 3), HBV DNA (+) after LAM (LAM resistance/Adefovir [ADV] unavailable); group D (n = 2), HBV DNA (+), no antiviral pretreatment; and group E (n = 2), HBV DNA (-) after LAM + ADV (LAM resistance/ADV available). Five patients died within 12 months after OLT unrelated to HBV infection. The remaining 35 patients were followed for a median duration of 16 months (range, 6-93 months). Only two recipients from group C, who were transplanted despite LAM resistance + no ADV pretreatment, revealed recurrent HBV infections at 14 and 16 months posttransplantation; they were then treated successfully with ADV as it became available. The third group C recipient had undetectable HBV DNA at 18 months after OLT. The mean cumulative doses of HBIG administered within the first, second, and third years were 34,014, 5258, and 5090 IU, respectively. In conclusion, low-dose, on-demand, intramuscular HBIG plus (LAM +/- ADV) prophylaxis is a safe, efficient, and cost-effective regimen to prevent recurrent HBV infection following OLT. OLT despite untreated LAM resistance may require sustained higher serum HBsAb levels after surgery.
