  2. Novel Biliary Reconstruction Techniques During Liver Transplantation (United States)

    Carmody, Ian C.; Romano, John; Bohorquez, Humberto; Bugeaud, Emily; Bruce, David S.; Cohen, Ari J.; Seal, John; Reichman, Trevor W.; Loss, George E.


    Background: Biliary complications remain a significant problem following liver transplantation. Several surgical options can be used to deal with a significant size mismatch between the donor and recipient bile ducts during the biliary anastomosis. We compared biliary transposition to recipient biliary ductoplasty in cadaveric liver transplant. Methods: A total of 33 reconstructions were performed from January 1, 2005 to December 31, 2013. In the biliary transposition group (n=23), 5 reconstructions were performed using an internal stent (5 or 8 French pediatric feeding tube), and 18 were performed without. Of the 10 biliary ductoplasties, 2 were performed with a stent. All patients were managed with standard immunosuppression and ursodiol. Follow-up ranged from 2 months to 5 years. Results: No patients in the biliary transposition group required reoperation; 1 patient had an internal stent removed for recurrent unexplained leukocytosis, and 2 patients required endoscopic retrograde cholangiography and stent placement for evidence of stricture. Three anastomotic leaks occurred in the biliary ductoplasty group, and 2 patients in the biliary ductoplasty group required reoperation for biliary complications. Conclusion: Our results indicate that biliary reconstruction can be performed with either biliary transposition or biliary ductoplasty. These techniques are particularly useful when a significant mismatch in diameter exists between the donor and recipient bile ducts.

    Lausada, Natalia R; Gondolesi, G E; Ortiz, E; Dreizzen, E; Raimondi, J C


    The orthotopic rat liver transplant model is a widely used technique in transplantation research. It has many advantages over other animal transplant models because of its availability and low cost. However, it must be emphasized that success with the rat model requires thorough training. The aim of this paper is to describe the microsurgical technique involved in 60 rat liver transplants and to discuss the complications and their treatments. Forty-nine liver transplants were performed at the Experimental Laboratory of the University Hospital, Ontario, Canada (ELUH) and 11 were performed at the Laboratorio de Trasplante de Organos de la Facultad de Ciencias Médicas de La Plata, Buenos Aires. Argentina (LTO). Among the transplants performed at the ELUH, the observed complications were haemorrhage (n = 4), pneumothorax (n = 1), anastomotic failure (n = 15), bile leak (n = 3), and bile duct necrosis (n = 9). The remaining 17 rats at the ELUH were healthy at day 7 after surgery. Animal survival immediately postop, at 24 hours postop and at 7 days postop was achieved with the 9th, 20th and 21st transplants respectively. At the LTO, 3 rats died as a result of anaesthetic complications. Seven-day animal survival was achieved with the 11th transplant. We beleive that the description of the orthotopic rat liver transplantation technique, as well as the discussion regarding complications and their management, can be useful for researchers interested in performing liver transplantation in rats.

    Conclusion: Our results indicate that the novel technique used in this study contributed to overcoming early and late postoperative complications associated with closure of the abdominal fascia in liver transplant patients. In addition, this new technique has proven to be easily applicable, faster, safer and efficient in these patients; it is also potentially useful for conventional surgery.

  5. Combined Piggyback Technique and Cavoportal Hemitransposition for Liver Transplant

    Full Text Available Portal Vein thrombosis (PVT increases the difficulty of liver transplant; however, it is not an absolute contraindication. Cavoportal hemitransposition (CPH is an option for patients with complete PVT and no alternative collateral vein. Our center often performs the piggyback technique for the hepatic vein reconstruction, which allows for great access to the recipient vena cava in patients with known complete PVT that may need a CPH preformed to successfully restore flow to the portal system of the donor liver. We describe the use of the piggy-back technique to prepare the vena cava for possible CPH in patients with known complete PVT.

    @@ In response to critical organ shortage, transplant surgeons have utilized living donors in an attempt to decrease the mortality rate associated with waiting on the liver transplant list. Although the surgical techniques were first utilized clinically 15 years ago, the application of living donor liver transplantation (LDLT) has been somewhat limited by the steep learning curve associated with developing a program.

    Teegen, Eva Maria; Denecke, Timm; Eisele, Robert; Lojewski, Christian; Neuhaus, Peter; Chopra, Sascha Santosh


    Liver transplantation has been established as a first-line therapy for a number of indications. Conventional ultrasound and contrast-enhanced ultrasound (CEUS) are methods of choice during the postoperative period as a safe and fast tool to detect potential complications and to enable early intervention if necessary. CEUS increases diagnostic quality and is an appropriate procedure for the examination of vessels and possibly bile ducts. This article presents the state of the art of ultrasound application during the early period after liver transplantation. It addresses common vascular complications and describes the identification of postoperative abnormal findings using ultrasound and CEUS.

    @@ Liver transplantation was developed for the treatment of hepatic failure, and the first human liver transplantation was done in 1963. From the 1990 s,liver transplantation was generally accepted as a treatment modality for both end-stage liver disease and selected liver malignancies. Initially, liver transplantation was started with deceased donor whole-size liver transplantation (whole-size LT) as in other organ transplantation, but there is now a shortage of deceased liver donors has occurred. As a solution, deceased donor split liver transplantation (split LT) began in 1989 and living donor liver transplantation (LDLT) in the early 1990 s. Current liver transplantation techniques include whole-size LT, reduced-size liver transplantation (reduced-size LT), split LT and single or dual LDLT. Two donors give a part of their livers to one adult recipient simultaneously in dual LDLT.

    Ishii, Eiichi; Shimizu, Akira; Takahashi, Mikiko; Terasaki, Mika; Kunugi, Shinobu; Nagasaka, Shinya; Terasaki, Yasuhiro; Ohashi, Ryuji; Masuda, Yukinari; Fukuda, Yuh


    Orthotopic liver transplantation (OLT) in rats is technically feasible and useful for the assessment of clinical liver transplantation and analysis of inflammatory liver diseases. OLT in rats was pioneered by Lee et al. in 1973 using hand-suture techniques of all vessels. This model has not been widely used due to the long operative time and technical demand. The cuff method was introduced by Kamada in 1979, and today, the Kamada technique is the one most commonly used worldwide. However, this technique does not include hepatic artery reconstruction, although this procedure is routinely performed in clinical transplantation. Nevertheless, several techniques for hepatic artery reconstruction in rat OLT have been reported recently, and our group also developed a simple splint technique from recipient right renal artery to donor celiac axis bearing the hepatic artery. In the present article, we describe the Kamada technique, as a standard surgical method for rat OLT. In addition, we also describe our splint technique for hepatic artery reconstruction. Then, we compare the features of Kamada technique and our splint technique for hepatic artery reconstruction and all other surgical techniques currently in use for rat OLT. The widespread use of the rat OLT model should help to provide full assessment of transplant immunology and the mechanism and treatment of inflammatory liver diseases.

  11. Improved technique of heterotopic auxiliary rat liver transplantation with portal vein arterialization. (United States)

    Schleimer, Karina; Stippel, Dirk L; Tawadros, Samir; Hölzen, J; Hölscher, A H; Beckurts, K Tobias E


    In acute, potentially reversible hepatic failure, auxiliary liver transplantation is a promising alternative approach. Using the auxiliary partial orthotopic liver transplantation (APOLT) method--the orthotopic implantation of auxiliary segments--most of the technical problems (lack of space for the additional liver mass, the portal vein reconstruction, and the venous outflow) are avoided, but extensive resections of the native liver and the graft are necessary. Erhard described the heterotopic auxiliary liver transplantation (HALT) with portal vein arterialization (PVA). Initial clinical results demonstrated that an adequate liver function can be achieved using this technique. We developed and improved a technique of HALT with flow-regulated PVA in the rat to perform further investigations. The aim of this paper is to explain in detail this improved experimental surgical technique. Liver transplantations were performed in 122 male Lewis rats: After a right nephrectomy, the liver graft, which was reduced to about 30% of the original size, was implanted into the right upper quadrant of the recipient's abdomen. The infrahepatic caval vein was anastomosed end-to-side. The donor's portal vein was completely arterialized to the recipient's right renal artery in stent technique. Using a stent with an internal diameter of 0.3 mm, the flow in the arterialized portal vein was regulated to achieve physiologic parameters. The celiac trunk of the graft was anastomosed to the recipient's aorta, end-to-side. The bile duct was implanted into the duodenum. After improvements of the surgical technique, we achieved a perioperative survival of 90% and a 6-week survival of 80% in the last 112 transplantations. We developed a standardized and improved technique, which can be used for experiments of regeneration and inter-liver competition in auxiliary liver transplantation. Furthermore, this technique is suitable for the investigation of the influence of portal vein arterialization and

    Seventy-five thousand Americans develop organ failure each year. Fifteen percent of those on the list for transplantation die while waiting. Several possible mechanisms to expand the organ pool are being pursued including the use of extended criteria donors, living donation, and split deceased donor transplants. Cadaveric organ splitting results from improved understanding of the surgical anatomy of the liver derived from Couinaud. Early efforts focused on reduced-liver transplantation (RLT) reported by both Bismuth and Broelsch in the mid-1980s. These techniques were soon modified to create both a left lateral segment graft appropriate for a pediatric recipient and a right trisegment for an appropriately sized adult. Techniques of split liver transplantation (SLT) were also modified to create living donor liver transplantation. Pichlmayr and Bismuth reported successful split liver transplantation in 1989 and Emond reported a larger series of nine split procedures in 1990. Broelsch and Busuttil described a technical modification in which the split was performed in situ at the donor institution with surgical division completed in the heart beating cadaveric donor. In situ splitting reduces cold ischemia, simplifies identification of biliary and vascular structures, and reduces reperfusion hemorrhage. However, in situ splits require specialized skills, prolonged operating room time, and increased logistical coordination at the donor institution. At UCLA over 120 in situ splits have been performed and this technique is the default when an optimal donor is available. Split liver transplantation now accounts for 10% of adult transplantations at UCLA and 40% of pediatric transplantations.

  14. A comparative study of the classic and piggyback techniques for orthotopic liver transplantation

    Directory of Open Access Journals (Sweden)

    Saman Nikeghbalian


    Full Text Available Background: The classic technique of hepatectomy with venovenous bypass may cause a longer anhepatic phase and increase the rate of some complications, such as post-operative renal failure and thromboembolic events. But, in some cases, such as tumors and anatomic difficulties, the surgeon is obligated to use the classic technique even though there is some controversy about the safety of this technique without venovenous bypass in liver transplantation. The aim of this study was to compare the results of using the classic technique without venovenous bypass and the piggyback technique for liver transplantation. Methods: A retrospective case-series study was conducted on 227 consecutive successful liver transplants, including 55 cases in which the classic technique was used and 172 cases in which the piggyback technique was used. The transplants were performed from March 2010 through June 2011 in the Visceral Transplantation Ward at Namazi Hospital in Shiraz, Iran. The piggyback method was the preferred approach for hepatectomy, but the classic technique without venovenous bypass was performed in cirrhotic cases with anatomic difficulties, when there was a tumor, or when the surgeon preferred it. Results: There were no significant differences in post-operative rise in creatinine, decreases in intraoperative blood pressure, transfused packed red blood cells (RBC, or survival rates between the groups. Warm ischemic time (duration that donor liver is out of ice until it’s blood reperfusion in the recipient was approximately seven minutes longer in the classic group (P = 0, but it was less than 52 minutes, which is an acceptable time for this phase. Hospital stays were shorter in the classic group than in the piggyback group (P = 0.024. Conclusion: Although the piggyback technique is the preferred technique for hepatectomy in liver transplantation, the classic technique without venovenous bypass can be used safely in cirrhotic livers when necessary

  15. Patient selection for liver transplantation. (United States)

    Carrion, Andres F; Aye, Lydia; Martin, Paul


    Improved outcomes in liver transplant recipients reflect advances in surgical technique, post-operative care, immunosuppression as well as better selection of potential candidates. The pre-transplant evaluation is a multidisciplinary process intended to recognize and treat important comorbid conditions that may impair outcomes during the peri- and post-transplant periods. Important psychosocial issues should also be ascertained and tackled early during the pre-transplant evaluation with an overarching intention to improve the success of liver transplantation.

    AIM: As the conventional combined liver-small bowel transplantation is complicated with many postoperative complications, the aim of this study was to describe a modified technique for the combined liver-small bowel transplantation with preservation of the duodenum, partial head of pancreas and hepatic biliary system in pigs.METHODS: Composite liver/small bowel allotransplantations were undertaken in 30 long-white pigs. The graft included liver, about 3 to 4 m proximal jejunum, duodenum and partial pancreatic head. Vessels reconstructions included subhepatic vena cava-vena cava anastomosis, aorta-aorta anastomosis and portal-splenic vein anastomosis.RESULTS: Without immunosuppressive treatment, the median survival time of the animals was 6 days (2 to 12days), and about 76.9 % (20/26) of the animals survived for more than 4 days after operation.CONCLUSION: The modified technique is feasible and safe for the composite liver/small bowel transplantation with duodenum and pancreas preserved in pigs. And also this technique can simplify the operation and decrease possible postoperative complications.

  2. Blood Conservation Strategies and Liver Transplantation Transfusion-Free Techniques Derived from Jehovah's Witness Surgical Cohorts. (United States)

    Sheth, Mansi; Kulkarni, Sujit; Dhanireddy, Kiran; Perez, Alexander; Selby, Rick


    Red blood cell and component transfusions are a frequent and widely accepted accompaniment of surgical procedures. Although the risk of specific disease transmission via allogeneic blood transfusions (ABT) is very low, the occurrence of transfusion related immune modulation (TRIM) still remains a ubiquitous concern. Recent studies have shown that ABT are linked to increased morbidity and mortality across various specialties, with negative outcomes directly correlated to number of transfusions. Blood conservation methods are therefore necessary to reduce ABT. Acute normo-volemic hemodilution (ANH) along with pre-operative blood augmentation and intraoperative cell salvage are blood conservation techniques utilized in tertiary and even quaternary (transplantation) surgery in Jehovah's Witnesses with excellent outcomes. The many hematologic complications such as anemia, thrombocytopenia and coagulopathies that occur with liver transplantation present a significant barrier when trying to avoid ABT. Despite this, living donor liver transplantation (LDLT) has been successfully performed in a transfusion-free environment, providing valuable insight into the possibilities of limiting ABT and its associated risks in all patients.

    Oldani, Graziano; Maestri, Marcello; Gaspari, Annalisa; Lillo, Ettore; Angelastri, Giacomo; Lenti, Luca Matteo; Rademacher, Johannes; Alessiani, Mario; Dionigi, Paolo


    The clinical success of liver transplantation is founded upon years of experimental research. Since Kamada and colleagues developed the "two-cuff" technique, the rat has become the best model for extensive investigations. Although the Kamada technique is technically complex and not easy to master, it is still the mainstay of orthotopic liver transplantation in rodents. We have developed a modified three-cuff version of this technique that facilitates anastomosis and markedly reduces warm ischemia time. The new technique involves a set of five microinstruments (the Quick-Linker system) designed and manufactured by our group. It was tested in male Lewis rats (group 1, donors n = 10, recipients n = 10). The graft was explanted as usual and standard cuffs were attached to the portal vein and the supra- and infrahepatic vena cavae. Corresponding vessels in the recipient were isolated, and Quicker-Linker holding rings were attached to each. The vessels were then clamped and the native organ removed. Once the graft was positioned in the recipient's abdomen, the holding rings attached to the recipient vessels and the cuffs applied to graft vessels were automatically aligned and joined with the aid of a special alignment tool. Warm ischemia times were always inferior to 6 minutes. Survival at postoperative day 10 was 80%. Liver function was well preserved in all of the surviving rats. The Quick-Linker technique significantly shortens warm ischemia time and allows rapid anastomosis that is relatively independent of operator skill. It can be considered a reliable option for microsurgeons looking for quick results and high success rates.

    Kidney transplantation after liver transplanta-tion (KALT) offers longer survival and a better quality of life to liver transplantation recipients who develop chronic renal failure. This article aimed to discuss the efifcacy and safety of KALT compared with other treatments. The medical records of 5 patients who had undergone KALT were retrospectively studied, together with a literature review of studies. Three of them developed chronic renal failure after liver transplanta-tion because of calcineurin inhibitor (CNI)-induced neph-rotoxicity, while the others had lupus nephritis or non-CNI drug-induced nephrotoxicity. No mortality was observed in the 5 patients. Three KALT cases showed good prognoses, maintaining a normal serum creatinine level during entire follow-up period. Chronic rejection occurred in the other two patients, and a kidney graft was removed from one of them. Our data suggested that KALT is a good alternative to dialysis for liver transplantation recipients. The cases also indicate that KALT can be performed with good long-term survival.

  5. Development of a New Technique for Reconstruction of Hepatic Artery during Liver Transplantation in Sprague-Dawley Rat.

    Directory of Open Access Journals (Sweden)

    Xingmu Liu

    Full Text Available Sleeve anastomosis is the most common technique used to rearterialize orthotopic liver transplants (OLT. However, this technique has a number of disadvantages, including difficulty of performance of the technique visually unaided. We herein describe a novel rearterialized OLT model in the rat.Forty-six male Sprague Dawley rats (300-400 g were used as donors and recipients. Based on Kamada's cuff technique, the new model involved performing a modified "sleeve" anastomosis between the celiac trunk of the donor and common hepatic artery of the recipient to reconstruct blood flow to the hepatic artery. An additional ten male Sprague Dawley rats underwent liver transplantation without artery reconstruction. Liver grafts were retrieved from the two groups and histological examination was performed following surgery.Total mean operating times were ~42 minutes for the donor liver extraction and 57 minutes for the recipient transplantation. Graft preparation took an additional 15 minutes and the time to fix the arterial bracket was ~3 minutes. During transplantation, the anhepatic phase lasted 18 ± 2.5 min and the artery reconstruction only required ~3 minutes. The patency rate was 94.44% and the 4-week survival rate was 90%. Histology indicated obvious fibrosis in the liver grafts without artery reconstruction, while normal histology was observed in the arterialized graft.This new method allows for the surgical procedure to be performed visually unaided with good survival and patency rates and represents an alternative model investigating OLT in rats.

    Right lobe living donor liver transplantation form a major source of liver allografts in Asia because of the scarcity of deceased donation. However, the transplant surgeons often face challenges while managing right lobe liver allografts due to variations in vascular anatomy. Such variations have led the transplant team to adopt modifications in existing techniques of inflow and outflow reconstruction. One of such variations is presence of multiple draining inferior right hepatic veins (IRHVs). This hepatic venous anomaly pose a lot of technical difficulties in the outflow reconstruction as second and/or third anastomosis to inferior vena cava is not always possible in limited retrohepatic space. Herein, we describe the "Single oval ostium technique" using dual synthetic vascular grafts ensuring a common outflow channel for all the hepatic veins.

    In previous decades, pediatric liver transplantation has become a state-of-the-art operation with excellent success and limited mortality. Graft and patient survival have continued to improve as a result of improvements in medical, surgical and anesthetic management, organ availability, immunosuppression, and identification and treatment of postoperative complications. The utilization of split-liver grafts and living-related donors has provided more organs for pediatric patients. Newer immunosuppression regimens, including induction therapy, have had a significant impact on graft and patient survival. Future developments of pediatric liver transplantation will deal with long-term followup, with prevention of immunosuppression-related complications and promotion of as normal growth as possible. This review describes the state-of-the-art in pediatric liver transplantation.

  13. Liver transplantation in Germany. (United States)

    Tacke, Frank; Kroy, Daniela C; Barreiros, Ana Paula; Neumann, Ulf P


    Liver transplantation (LT) is a well-accepted procedure for end-stage liver disease in Germany. In 2015, 1489 patients were admitted to the waiting list (including 1308 new admissions), with the leading etiologies being fibrosis and cirrhosis (n = 349), alcoholic liver disease (n = 302), and hepatobiliary malignancies (n = 220). Organ allocation in Germany is regulated within the Eurotransplant system based on urgency as expressed by the Model for End-Stage Liver Disease score. In 2015, only 894 LTs (n = 48 from living donors) were performed at 23 German transplant centers, reflecting a shortage of organs. Several factors may contribute to the low number of organ donations. The German transplant legislation only accepts donation after brain death (not cardiac death), whereas advances in neurosurgery and a more frequently requested "palliative care" approach render fewer patients suitable as potential donors. The legislation further requires the active consent of the donor or first-degree relatives before donation. Ongoing debates within the German transplant field address the optimal management of patients with alcoholic liver cirrhosis, hepatocellular carcinoma (HCC), and cholangiocarcinoma and measures to increase living donor transplantations. As a result of irregularities at mainly 4 German transplant centers that were exposed in 2012, guiding principles updated by the German authorities have since implemented strict rules (including internal and external auditing, the 8-eyes principle, mandatory repeated testing for alcohol consumption) to prohibit any manipulations in organ allocation. In conclusion, we will summarize important aspects on the management of LT in Germany, discuss legal and organizational aspects, and highlight challenges mainly related to the relative lack of organ donations, increasing numbers of extended criteria donors, and the peculiarities of the recipient patients.

    Background Although liver transplantation has become a standard therapy for end-stage liver diseases, the experience of pediatric liver transplantation is limited in China. In this article we report our experience in pediatric liver transplantation, and summarize its characters in their indications, surgical techniques, and postoperative managements. Methods Thirty-one children (≤18 years old) underwent liver transplantation in our centers. The mean age at transplantation was 12.4 years old (ranged from 5 months to 18 years) with 7 children being less than 4 years of age at transplantation. The most common diagnosis of patients who underwent liver transplantation were biliary atresia, Wilson's disease, primary biliary cirrhosis, glycogen storage disease, hepatoblastoma, urea cycle defects, fulminant hepatic failure, etc. The surgical procedures included 12 standard (without venovenous bypass), 6 pigyback, 6 reduced-size, 3 split, 3 living donor liver transplantation, and 1 Domino liver transplantation. The triple-drug (FK506, steroid, and mycophenolate mofetil) immunosuppressive regimen was used in most of patients. Patients were followed up for a mean of 21.8 months. Results Five of the 31 patients died during perioperative time; mortality rate was 16.1%. The reasons of death were infections, primary non-function, heart failure, and hypovolemic shock. Postoperative complications in 10 patients included biliary leakage, acute rejection, abdominal infection, hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, and pulmonary infection. Overall patient cumulative survival rate at 1-, 3-, and 5-year was 78.1%, 62.6%, 62.6%, respectively.Conclusions The most common indications of pediatric liver transplantation were congenital end-stage liver diseases.

    Hepatocellular carcinoma (HCC is the fifth most common cancer worldwide, and is the leading cause of death in cirrhotic individuals. 80% of HCC develops in cirrhotic patients. Unfortunately only 20 to 25% of patients can have a radical treatment, like resection, liver transplantation (LT, or percutaneous ablation. The other 75 to 80% of patients can only have supportive care.

    There is no evidence to establish the optimal first-line treatment for early HCC (one tumor of 5 cm or less, in patients with well preserved liver function, because of the lack of RCTs comparing these radical therapies. Resection and transplantation achieve a very good outcome (5-year survival of 60 to 70% but with very different recurrence rates (60-70% and 15-20% respectively. Due to the lack of liver donors, these two techniques compete as the first option for treatment in cirrhotic patients with well preserved liver function and only one tumor.

    There is no question in considering LT as the best option for patients with liver function impairment (Child-Pugh B-C patients and early tumors (less than three tumors of less than three centimeters. LT provides cure of both the neoplastic disease and the underlying liver disease. There are a few numbers of reports that shows a decrease in the overall survival, from an intention-to treat perspective as a result of the impact of dropouts from the waiting list because of death or progression. These numbers can be as high as 20%. Adjuvant therapies during the waiting period, although intuitively effective, have not had an impact on the outcome. Expansion of the accepted Milan criteria (single nodule <5 cm, two or three nodules <3 cm has been advocated by some groups

    Grecu, F


    An overview of the organization, timing and developing of the liver transplantation is difficult to be made in terms of multiple sequences and a great variety of activities during the developing of such activity. A well-trained transplant team must carry out the potential donor, the liver grafts manipulation and the graft receptor, in the condition of a competitive medical system. A summary presentation, showing the essentials of the proceedings in liver transplantation could be assimilated as a guide of multidisciplinary sequences that leads to the completion of the liver grafting. The common feature of all that means the liver transplantation and generally in organ transplantation is the performance and exactingness.

    To assess the clinical efficacy of alternative techniques for biliary stricture cannulation in patients undergoing living donor liver transplantation (LDLT), after cannulation failure with a conventional (0.035-inch guidewire) technique. Of 293 patients with biliary strictures after LDLT, 19 (6%) patients, 11 men and 8 women of mean age 48.5 years, had the failed cannulation of the stricture by conventional techniques. Recannulation was attempted by using two alternative methods, namely a micro-catheter set via percutaneous access and a snare (rendezvous) technique using percutaneous and endoscopic approaches. Strictures were successfully cannulated in 16 (84%) of the 19 patients. A microcatheter set was used in 12 and a snare technique in four patients. Stricture cannulation failed in the remaining three patients, who finally underwent surgical revision. Most technical failures using a conventional technique for biliary stricture cannulation after LDLT can be overcome by using a microcatheter set or a snare (rendezvous) technique.

    Initially considered experimental, liver transplantation (LT) has become the treatment of choice for the patients with end-stage liver diseases. Between April 2000 and October 2009, 200 LTs (10 reLTs) were performed in 190 patients, this study being retrospective. There were transplanted 110 men and 80 women, 159 adults and 31 children with the age between 1 and 64 years old (mean age--39.9). The main indication in the adult group was represented by viral cirrhosis, while the pediatric series the etiology was mainly glycogenosis and biliary atresia. There were performed 143 whole graft LTs, 46 living donor LTs, 6 split LTs, 4 reduced LTs and one domino LT RESULTS: The postoperative survival was 90% (170 patients). The patient and graft one-year and five-year survivals were 76.9%, 73.6% and 71%, 68.2%, respectively. The early complications occurred in 127 patients (67%). The late complications were recorded in 71 patients (37.3%). The intraoperative and early postoperative mortality rate was 9.5% (18 patients). The Romanian liver transplantation program from Fundeni includes all types of current surgical techniques and the results are comparable with those from other international centers.

  1. Does the standard vs piggyback surgical technique affect the development of early acute renal failure after orthotopic liver transplantation? (United States)

    Cabezuelo, J B; Ramirez, P; Acosta, F; Torres, D; Sansano, T; Pons, J A; Bru, M; Montoya, M; Rios, A; Sánchez Bueno, F; Robles, R; Parrilla, P


    The objective of this study was to evaluate the effect of the surgical technique on postoperative renal function during the first week after liver transplantation (OLT). We performed a retrospective study of 184 consecutive OLT. Criteria for acute renal failure were: serum creatinine >1.5 mg/dL, an increase by 50% in the baseline serum creatinine, or oliguria requiring renal replacement therapy. The distribution of patients according to the surgical technique was: standard (n=84), venovenous bypass (n=20), and piggyback (n=80). Other variables analyzed were: intraoperative requirement for blood products, treatment with adrenergic agonists, intraoperative complications, and postreperfusion syndrome. Univariate analysis showed the following parameters to be significantly related to postoperative renal failure: intraoperative fresh frozen plasma and cryoprecipitate requirements, intraoperative complications, postreperfusion syndrome, need for noradrenaline or dobutamine, standard surgical technique versus piggyback (39% vs 18%, P20 U cryoprecipitate requirement (OR=1.04, P=.01). In conclusion, compared with the piggyback technique, the standard surgical technique appears to be an independent risk factor for postoperative acute renal failure. When venovenous bypass is used in patients who do not tolerate trial clamping of inferior vena cava, it does not reduce the incidence of postoperative renal failure. Finally, the piggyback technique significantly reduces the probability of acute renal failure after liver transplantation.

  2. Comparison of different MRCP techniques for the depiction of biliary complications after liver transplantation

    Biliary strictures after liver transplantation are common. We aimed to compare different magnetic resonance cholangiopancreatography (MRCP) sequences with regard to their diagnostic accuracy in depicting anastomotic stenoses (AST), ischaemic-type biliary lesions (ITBL) and cholelithiasis. In patients with clinically suspected biliary obstruction after liver transplantation, MRCP was performed at 1.5 T using two-dimensional (2D) single-shot RARE, 2D T2-weighted (T2w) HASTE, 2D TrueFISP and 3D T2w TSE RESTORE sequences. The presence and localisation of lesions were assessed for each sequence independently and all sequences together. Endoscopic retrograde cholangiopancreatography (ERCP) served as the ''gold standard''. Biliary strictures were detected with a sensitivity of 96% by MRCP and most accurately depicted when all sequences were analysed together. AST was visualised with highest sensitivity on TrueFISP and 3D T2w TSE sequences (79%). For ITBL highest sensitivity was found with the HASTE sequence (81%). Highest sensitivity for filling defects was revealed by the 3D T2w TSE sequence (54%). Receiver operating characteristic (ROC) curve/area under the curve (AUC) analysis revealed the best results for the 3D T2w TSE sequence. Our results underline the value of different MRCP sequence types for the depiction of biliary lesions. A clinical protocol consisting of different sequences may be helpful depending on the clinical question and the likely underlying abnormality. (orig.)

  3. [Liver transplantation and pregnancy]. (United States)

    Goarin, A-C; Homer, L


    Management during their sexual life of patients with a liver transplantation is a more or less common situation depending centers. Based on literature review, a focus on management of recipient women was conducted, from contraception to pregnancy, describing the complications related to the status of transplant recipient, but also those that may be related to immunosuppressive agents. If fertility and access to contraception are only slightly modified by graft, complications related to graft or immunosuppressive drugs can affect the pregnancy. On the maternal side, hypertension and preeclampsia are more common, as well as renal dysfunction, iatrogenic diabetes and bacterial or viral infections, acute rejection and graft loss do not appear to be influenced by pregnancy. The fetus is also exposed to risks such as induced prematurity and IUGR. Pregnancy in recipients of hepatic grafts therefore requires joint follow-up by transplant specialist and perinatologist, which leads in most cases to successful outcome for mother and child.

    Orthotopic liver transplantation (OLT) in rats is frequently used as an experimental model. Numerous surgical techniques have been developed that enable the investigator to conduct clinically relevant studies. The objective of this study was to develop a rat model of acute and chronic rejection, to explicitly study technical modifications of vascular anastomoses with precision, and to examine histopathologic and functional changes in the graft. With DA-(RT1av1) rats as donors and Lewis-(RT1) rats as recipients, arterialized OLT was performed using a combined suture, cuff, and splint method. Recipients were divided into 5 groups: syngeneic control rats (group 1), allogeneic control rats (group 2), allogeneic OLT rats with low-dose tacrolimus (FK506) immunosuppression (group 3), allogeneic OLT rats with high-dose tacrolimus immunosuppression (group 4), and allogeneic OLT rats with high-dose tacrolimus immunosuppression and retrograde reperfusion via the infrahepatic caval vein (group 5). After OLT, serum parameters were determined and hepatic biopsy specimens were sampled. We examined the effects of acute rejection with or without immunosuppression therapy at histopathologic evaluation. Liver grafts in syngeneic and allogeneic rats (groups 1, 2, 4, and 5) demonstrated normal serum parameters and histopathologic findings at 10 days after OLT, and 93% survival at 3 months. The simplified technique using 1 suture and 2 cuff anastomoses provided the best short- and long-term survival after OLT in all groups. Retrograde perfusion via the infrahepatic caval vein resulted in lower postoperative liver enzyme values. The present model is feasible, enabling comprehensive preclinical experimental research on liver transplantation. Furthermore, we provide helpful instructions for learning this surgical technique.

    Biliary anastomosis stricture (BAS) is still among the major concerns after living donor liver transplantation (LDLT), even after the technical refinements including the universal use of the blood flow-preserving hilar dissection technique. The aim of this study is to investigate what are still the factors for BAS after LDLT. An analysis of 279 adult-to-adult LDLT grafts (left lobe, n = 161; right lobe, n = 118) with duct-to-duct biliary reconstruction, since the universal application of minimal hilar dissection technique and gradual introduction of eversion technique, was performed. There were 39 patients with BAS. Univariate analysis showed that a right lobe graft (P = 0.008), multiple bile ducts (P dissection technique could be a key for preventing BAS in duct-to-duct biliary reconstruction in LDLT.

    Obesity is an important public health and medical concern in the United States. The rate of obesity has steadily risen for the past several decades. Obesity is associated with the development of nonalcoholic steatohepatitis, which is one of the leading indications for liver transplantation. After liver transplantation, recipients tend to gain weight and develop recurrent fatty liver. Over time, recurrent fatty liver may impact patient and graft survival. A bariatric surgical approach may be beneficial in select patients.

    Schilsky, Michael L


    Although Wilsons's disease (WD) may be treated with copper chelation (to remove copper) or zinc salts (to prevent absorption) to alleviate or prevent symptom development in most patients, there are WD patients for whom medical therapy is inadequate and survival would be unlikely without liver transplantation. Liver transplantation is indicated for the ∼5% of WD patients with acute liver failure as the first presentation of disease, most commonly in the second decade of life, or those who present with end-stage liver disease and severe hepatic insufficiency, most commonly in the third and fourth decades. Liver transplantation restores normal biliary copper excretion (thereby preventing disease recurrence) and promotes removal of copper from extrahepatic sites. Outcomes of liver transplantation for WD are excellent, including both cadaveric and living donors.

    Liver transplantation with preservation of the recipient vena cava (piggyback technique) has been performed as an alternative to the conventional method. Outflow disturbance or obstruction of the vena cava in the early period after liver transplantation is associated with high morbidity and mortality. We used side-to-side cavo-caval anastomosis (modified piggyback technique) in a deceased-donor liver transplantation (DDLT) for venous outflow reconstruction. On postoperative day 9, the patient developed abdominal discomfort, and abnormal liver function showing serum total bilirubin of 6.2 mg/dl and serum AST/ALT of 297/597 IU/L. Doppler ultrasound showed mono-phasic wave forms of the hepatic vein. Computed tomography showed focal narrowing of 9.5 mm×12 mm in diameter at the cavo-caval anastomosis site. Liver biopsy was showed that there was no evidence of acute allograft rejection. Direct venogram showed stenosis of the cavo-caval anastomosis with a pressure gradient of 12 mmHg. An interventional stent was inserted in the stenotic site of the inferior vena cava, and the pressure gradient decreased to 2 mmHg. He was discharged from hospital on postoperative day 23 without any other complications. Herein we report a case of deceased-donor liver transplantation using the modified piggyback technique, who received an inferior vena cava stent due to stricture of the reconstructed orifice of the vena cava.

    Carrion, Andres F; Bhamidimarri, Kalyan Ram


    Cholestatic liver diseases include a group of diverse disorders with different epidemiology, pathophysiology, clinical course, and prognosis. Despite significant advances in the clinical care of patients with cholestatic liver diseases, liver transplant (LT) remains the only definitive therapy for end-stage liver disease, regardless of the underlying cause. As per the United Network for Organ Sharing database, the rate of cadaveric LT for cholestatic liver disease was 18% in 1991, 10% in 2000, and 7.8% in 2008. This review summarizes the available evidence on various common and rare cholestatic liver diseases, disease-specific issues, and pertinent aspects of LT.

  12. Technical Skills Required in Split Liver Transplantation. (United States)

    Liu, Huanqiu; Li, Ruijun; Fu, Jinling; He, Qianyan; Li, Ji


    The number of liver grafts obtained from a cadaver can be greatly increased with the application of split liver transplantation. In the last 10 years, pediatric waiting list mortality has been reduced significantly with the use of this form of liver transplantation, which has 2 major forms. In its most commonly used form, the liver can be transplanted into 1 adult and 1 child by splitting it into a right extended and a left lateral graft. For adult and pediatric recipients, the results of this procedure are comparable to those of whole-organ techniques. In another form, 2 hemi-grafts are obtained by splitting the liver, which can be transplanted into a medium-sized adult (the right side) and a large child/small adult (the left side). The adult liver graft pool is expanded through the process of full right/full left splitting; but it is also a critical technique when one considers the knowledge required of the potential anatomic variations and the high technical skill level needed. In this review, we provide some basic insights into the technical and anatomical aspects of these 2 forms of split liver transplantation and present an updated summary of both forms.

    Objective: The aim of our study was to evaluate our liver transplant pediatric patients and to report our experience in the complications and the long-term follow-up results. Materials and Methods: Patients between the ages of 0 and 18 years, who had liver transplantation in the organ transplantation center of our university hospital between 1997 and 2016, were included in the study. The age, sex, indications for the liver transplantation, complications after the transplantation, and long-term follow-up findings were retrospectively evaluated. The obtained results were analyzed with statistical methods. Results: In our organ transplantation center, 62 pediatric liver transplantations were carried out since 1997. The mean age of our patients was 7.3 years (6.5 months–17 years). The 4 most common reasons for liver transplantation were: Wilson’s disease (n=10; 16.3%), biliary atresia (n=9; 14.5%), progressive familial intrahepatic cholestasis (n=8; 12.9%), and cryptogenic cirrhosis (n=7; 11.3%). The mortality rate after transplantation was 19.6% (12 of the total 62 patients). The observed acute and chronic rejection rates were 34% and 4.9%, respectively. Thrombosis (9.6%) was observed in the hepatic artery (4.8%) and portal vein (4.8%). Bile leakage and biliary stricture rates were 31% and 11%, respectively. 1-year and 5-year survival rates of our patients were 87% and 84%, respectively. Conclusion: The morbidity and mortality rates in our organ transplantation center, regarding pediatric liver transplantations, are consistent with the literature. PMID:28149148

    Shen, Zhongyang


    The liver transplant program at the transplant center of Tianjin First Center Hospital opened in 1994 and has become a leading center for academic research and development in clinical liver transplantation during the past 18 years. As of Nov 30, 2011, we had performed 4,103 liver transplantations in patients ranging from 6 months to 79 years old. Since 1998, the program has ranked first in mainland China in the annual number of liver transplants performed, the cumulative total liver transplants and the number of long-surviving patients. We've accomplished a number of "firsts" among the Chinese liver transplant centers, including: the first split liver transplantation, the first pediatric liver transplant, the first living donor simultaneous liver-kidney transplant, the first dual-graft liver transplant using a domino right lobe and a living donor left lobe, the first laparoscopic assisted live donor right hepatectomy including the middle hepatic vein and we have assembled the first liver transplant chain comprising multiple donors and recipients. We have performed the largest number of living related and split liver transplantations in mainland China. The combined prophylactic protocol of "Lamivudine and HBIG" to prevent HBV recurrence post transplantation was first used by our center in China and now is utilized by most of the domestic transplant centers. We have begun using livers from donors after cardiac death (DCD) during the past 2 years, with careful donor selection and recipient management. All the approaches and techniques we've developed are aimed at the utilization of all types of available grafts. However, increasing the rate of transplantation with excellent graft and recipient survival are still the challenges facing us.

  16. Overview of immunosuppression in liver transplantation

    Institute of Scientific and Technical Information of China (English)

    Anjana A Pillai; Josh Levitsky


    Continued advances in surgical techniques and immunosuppressive therapy have allowed liver transplantation to become an extremely successful treatment option for patients with end-stage liver disease. Beginning with the revolutionary discovery of cyclosporine in the 1970s, immunosuppressive regimens have evolved greatly and current statistics confirm one-year graft survival rates in excess of 80%. Immunosuppressive regimens include calcineurin inhibitors, anti-metabolites, mTOR inhibitors, steroids and antibody-based therapies. These agents target different sites in the T cell activation cascade, usually by inhibiting T cell activation or via T cell depletion. They are used as induction therapy in the immediate periand post-operative period, as long-term maintenance medications to preserve graft function and as salvage therapy for acute rejection in liver transplant recipients. This review will focus on existing immunosuppressive agents for liver transplantation and consider newer medications on the horizon.

  17. Liver transplantation for nontransplant physicians

    Full Text Available Many of the nontransplant physicians who manage hepatic patients (internists and hepatologists keep asking about liver transplantation. The purpose of this article is to highlight important topics a nontransplant colleague may require in his practice. There are many topics in this respect; however, three most important topics need to be highlighted; those are; the time of referral to transplantation, the indications and contraindications and the metabolic issues regarding a transplanted patient. Still, there are no clear guidelines for the management of many of the metabolic issues regarding liver transplanted patients. And this why, collaborative efforts of transplant and nontransplant physicians are needed to conduct multicenter, long term randomized controlled trials and proper follow up programs.

    The paper studies the combined radiologic and endoscopic approach (rendezvous technique) to the treatment of the biliary complications following liver transplant. The "rendez-vous" technique was used with an electrokinetic lithotripter, in the treatment of a biliary anastomotic stricture with multiple biliary stones in a patient who underwent orthotopic liver transplant. In this patient, endoscopic or percutaneous transhepatic management of the biliary complication failed. The combined approach, percutaneous transhepatic and endoscopic treatment (rendez-vous technique) with the use of an electrokinetic lithotritor, was used to solve the biliary stenosis and to remove the stones.Technical success, defined as disappearance of the biliary stenosis and stone removal, was obtained in just one session, which definitively solved the complications.The combined approach of percutaneous transhepatic and endoscopic (rendez-vous technique) treatment, in association with an electrokinetic lithotritor, is a safe and feasible alternative treatment, especially after the failure of endoscopic and/or percutaneous trans-hepatic isolated procedures.

    Background Liver transplantation in Budd-Chiari syndrome remains controversial; however, some improved techniques lead to better results. We report medium-term follow-up results of liver transplantation with atrioatrial anastomosis for Budd-Chiari syndrome and explore the indications of liver transplantation with atrioatrial anastomosis for patients with end stage liver disease.Methods Nine patients (six Budd-Chiari syndromes, one end stage hepatolithiasis, one hepatocellular carcinoma and one incurable alveolar echinococcosis) underwent liver transplantation with atrioatrial anastomosis in West China Hospital of Sichuan University from 1999 to 2006. Eight liver transplants used cadaveric orthotopic livers and one a living donor liver. The operative technique was transdiaphragmatic exposure for direct atrioatrial anastomosis and replacement of inferior vena cava by cryopreserved vena cava graft with the help of venovenous bypass.Results All liver transplantations were successful. Two patients contracted pulmonary infection and acute rejection took place in another case. With proper treatment, all patients recovered well and had good quality of life. To date, they have been followed up for more than 24 months. The only death followed recurrence of hepatic carcinoma three years after liver transplantation.Conclusions Transdiaphragmatic exposure for direct atrioatrial anastomosis and the cryopreserved vena cava graftreplacement of inferior vena cava are possible for patients with end stage liver disease thus extending the indications of liver transplantation.

    Patients with end-stage isolated polycystic liver disease (PCLD) suffer from incapacitating symptoms because of very large liver volumes. Liver transplantation (LT) is the only curative option. This study assesses the feasibility of LT in PCLD. We used the European Liver Transplant Registry (ELTR)

  5. The evolution of anterior sector venous drainage in right lobe living donor liver transplantation: does one technique fit all? (United States)

    Tokat, Yaman


    In living donor liver transplantation (LDLT), an adequate hepatic venous outflow constitutes one of the basic principles of a technically successful procedure. The issue of whether the anterior sector (AS) of the right lobe (RL) graft should or should not be routinely drained has been controversial. The aim of this 10-year, single-center, retrospective cohort study was to review the evolution of our hepatic venous outflow reconstruction technique in RL grafts and evaluate the impact of routine AS drainage strategy on the outcome. The study group consisted of 582 primary RL LDLT performed between July 2004 and December 2014. The cases were divided into 3 consecutive periods with different AS venous outflow reconstruction techniques, which included middle hepatic vein (MHV) drainage in Era 1 (n=119), a more selective AS drainage with cryopreserved homologous grafts in Era 2 (n=391), and routine segment 5 and/or 8 oriented AS drainage with synthetic grafts in Era 3 (n=72). Intraoperative portal flow measurement with routine splenic artery ligation (SAL) technique (in RL grafts with a portal flow of ≥ 250 mL/min/100 g liver tissue) was added later in Era 3. These 3 groups were compared in terms of recipient and donor demographics, surgical characteristics and short-term outcome. The rate of AS venous drainage varied from 58.8% in Era 1 and 35.0% in Era 2 to 73.6% in Era 3 (P<0.001). Perioperative mortality rate of recipients significantly decreased over the years (15.1% in Era 1 and 8.7% in Era 2 vs. 2.8% in Era 3, P=0.01). After the addition of SAL technique in the 45 cases, there was only 1 graft loss and no perioperative mortality. One-year recipient survival rate was also significantly higher in Era 3 (79.6% in Era 1 and 86.1% in Era 2 vs. 92.1% in Era 3, P=0.002). Routine AS drainage via segment 5 and/or 8 veins using synthetic grafts is a technique to fit all RL grafts in LDLT. Addition of SAL effectively prevents early graft dysfunction and significantly

  6. The history of liver transplantation in Turkey. (United States)

    Moray, Gökhan; Arslan, Gülnaz; Haberal, Mehmet


    Liver transplantation is the definitive treatment for end-stage liver diseases. The first successful liver transplant was performed in the United States by Thomas Starzl in 1967. The first successful solid organ transplant in Turkey was a living-related kidney transplant performed by Dr. Haberal in 1975. After much effort by Dr. Haberal, the Turkish parliament enacted a law about organ transplantation in 1979. After clinical and experimental studies, the first liver transplant in Turkey was performed by Dr. Haberal in 1988. The first successful partial living-donor liver transplant in children in Turkey was performed by the same team on March 15, 1990. On April 24, 1990, the first living-donor liver transplant was performed on a child in Turkey using a left lateral segment by Dr. Haberal and coworkers. On May 16, 1992, Dr. Haberal performed a simultaneous living-donor liver and kidney transplantation to an adult from the same donor. There currently are 30 liver transplantation centers in Turkey. According to data from the Ministry of Health, there presently are 2065 patients in Turkey who are waiting for a liver transplantation. From January 2002 to June 2013, there were 6091 liver transplants performed in Turkey (4020 living-donor [66% ] and 2071 deceased donor liver transplants [34% ]). From January 2011 to June 2013, there were 2514 patients who had liver transplants in Turkey, and 437 patients (17%) died. The number of liver transplants per year in Turkey reached 1000 transplants in 2012 and more than 1150 transplants in 2013 (15.1/million/y). Therefore, Turkey has one of the highest volumes of liver transplantation per population worldwide, with 90% survival within 1 year after transplantation.

    The filed of liver transplantation (LT) continues to evolve and is highly effective therapy for many patients with acute and chronic liver failure resulting from a variety of causes. Improvement of perioperative care, surgical technique and immunosuppression in recent years has led to its transformation into a safe and routine procedure with steadily improving results. The aim of this paper is to present the initial experience of the transplant team at Military Medical Academy - Sofia, Bulgaria. For the period of April 2007 - August 2014 the team performed 38 liver transplants in 37 patients (one retransplantation). Patients were followed up prospectively and retrospectively. In 36 (95%) patients a graft from a cadaveric donor was used and in two cases--a right liver grafts from live donor. The mean MELD score of the transplanted patients was 17 (9-40). The preferred surgical technique was "piggyback" with preservation of inferior vena cava in 33 (86%) of the cases and classical technique in 3 (8%) patients. The overall complication rate was 48%. Early mortality rate was 13% (5 patients). The overall 1- and 5-year survival is 81% and 77% respectivelly. The setting of a new LT program is a complex process which requires the effort and effective colaboration of a wide range of speciacialists (hepatologists, surgeons, anesthesiologists, psychologists, therapists, coordinators, etc.) and institutions. The good results are function of a proper selection of the donors and the recipients. Living donation is an alternative in the shortage of cadaveric donors.

    Institute of Scientific and Technical Information of China (English)


    In 1953, the pioneer of human orthotopic liver transplantation(LT), Thomas E Starzl, was the first to attemptan orthotopic liver transplant into a 3 years old patientsuffering from biliary atresia. Thus, the first LT in humanswas attempted in a disease, which, up until today,remains the main indication for pediatric LT (pLT). Duringthe last sixty years, refinements in diagnostics and surgicaltechnique, the introduction of new immunosuppressivemedications and improvements in perioperative pediatriccare have established LT as routine procedure forchildhood acute and chronic liver failure as well asinherited liver diseases. In contrast to adult recipients,pLT differs greatly in indications for LT, allocation practice,surgical technique, immunosuppression and postoperativelife-long aftercare. Many aspects are focus ofongoing preclinical and clinical research. The presentreview gives an overview of current developments andthe clinical outcome of pLT, with a focus on alternativesto full-size deceased-donor organ transplantation.

  10. Transplantation in autoimmune liver diseases (United States)

    Mottershead, Marcus; Neuberger, James


    Liver transplantation remains an effective treatment for those with end-stage disease and with intractable liver-related symptoms. The shortage of organs for transplantation has resulted in the need for rationing. A variety of approaches to selection and allocation have been developed and vary from country to country. The shortage of donors has meant that new approaches have to be adopted to make maximal use of the available organs; these include splitting grafts, use of extended criteria livers, livers from non-heart-beating donors and from living donors. Post transplantation, most patients will need life-long immunosuppression, although a small proportion can have immunosuppression successfully withdrawn. Newer immunosuppressive drugs and different strategies may allow a more targeted approach with a reduction in side-effects and so improve the patient and graft survival. For autoimmune diseases, transplantation is associated with significant improvement in the quality and length of life. Disease may recur after transplantation and may affect patient and graft survival. PMID:18528936

  13. [Alcoholic liver disease and liver transplantation]. (United States)

    Testino, Gianni; Patussi, Valentino; Scafato, Emanuele


    Alcoholic liver disease (ALD) is the second most common diagnosis among patients undergoing liver transplantation (LT) in Europe and in the United States. The outcome of patients transplanted for ALD is at least as good as that for most other diagnoses and better than that for hepatitis C virus. In case of severe acute alcoholic hepatitis (AAH) non-responders to medical therapy, the reason for denying LT is that it requires abstinence from alcohol for six months before consideration for a transplant. A strict application of a period of abstinence as a policy for transplant eligibility is unfair to non-responder patients, as most of them will have died prior to the end of the six-month sober period. In our opinion, in severe AAH subjects with a good social support, with the frequency of self-help groups (alcoholics anonymous or association of clubs of alcoholics in treatment), with the frequency of Alcohol Unit and without severe psychotic or personality disorders, the lack of pre-LT abstinence alone should not be a barrier against being listed.

  14. Better innovate than compromise: a novel hepatic outflow reconstruction technique in pediatric living donor liver transplantation. (United States)

    Cherian, P Thomas; Mishra, Ashish K; Bangaari, Ashish; Kota, Venugopal; Sathyanarayanan, Mohan; Raya, Ravichandra; Rela, Mohamed


    Pediatric LDLT using donors with unfavorable vascular anatomy is challenging in terms of donor safety, and complexity of reconstruction in the recipient. We describe an innovative technique of hepatic venous outflow reconstruction involving the recipient RHV, in the presence of a rudimentary RHV in the donor. The postoperative course of the donor and recipient was uneventful with satisfactory venous outflow in both. This technique avoided the use of prosthetic material, an important consideration given the recipient age and requirement for growth. This shows that donors previously considered unsuitable for donation can be utilized safely as long as principles of vascular anastomosis are adhered to. Moreover, it highlights that innovation is sometimes necessary to avoid compromise in donor safety.

  18. Liver Transplantation and Bariatric Surgery: Best Approach. (United States)

    Suraweera, Duminda; Dutson, Erik; Saab, Sammy


    Obesity has become increasingly prevalent, and the number of obese patients in need of liver transplant is expected to continue to increase. In addition, liver disease due to nonalcoholic fatty liver disease is expected to become the leading cause of liver transplantation in the near future. However, obesity remains a relative contraindication in liver transplant. New strategies in managing this patient population are clearly needed. To this end, the authors review the current literature on the efficacy of bariatric surgery in the setting of liver transplantation in obese patients. Copyright © 2016 Elsevier Inc.

    Over the past 5 years, we have employed several strategies to increase the donor pool for both the pediatric and adult populations. The innovative expansion of the donor pool with the use living-related donors for children and cadaveric, high-risk donors for adults has increased our ability to serve our recipients and transplant them at an earlier stage in the disease process, thereby improving survival. As Hepatitis C is now the leading indication for liver transplantation in the adult population, the investigation of the natural history of Hepatitis C prior to and after transplantation provides a major challenge and is currently a focus of both laboratory and clinical efforts. For those recipients of Hepatitis C-positive-donor livers, determining the role of recipient and donor genotypes in the progression of recurrent hepatitis should help define the proper utilization of these organs. For patients on CsA-based immunosuppression regimens who experience steroid-resistant rejection, tacrolimus has proved to be extremely effective in reversing the rejection episodes and maintaining normal graft function. The long-term results of this therapy appear to be superior to OKT3 therapy. The recipients of living-related liver transplantation continue to have a survival advantage in comparison to recipients of cadaveric grafts. The donor operation can be routinely performed with minimal risk. Because of the superior results achieved and minimal donor risks, we feel that providing the option of living-donor transplantation is ethically justified, and medically necessary. Despite the encouraging results from living-donor transplantation, unexpected complications including portal vein complications and hepatic artery thrombosis have forced technical modifications of the original technique which may have implications to pediatric liver transplantation in general. As the volume of pediatric liver transplants and the number of immmunosuppressive regimens have increased over the

  20. Bioengineering in organ transplantation: targeting the liver. (United States)

    Fukumitsu, K; Yagi, H; Soto-Gutierrez, A


    About 27,000 deaths are registered annually in the United States due to liver disease. At this time, the only definitive treatment of hepatic failure is orthotopic transplantation. However, there is a critical shortage of organs with the total waiting list for all organs currently at 100,000 requests. The number is increasing by 5% every year. Given that only organs in pristine condition are transplantable and that the hidden demand for organs as an anti-aging solution will be many times the current figures, orthotopic transplantation will always remain a limited pool. The increasing donor organ shortage requires consideration of alternative emerging technologies. Regenerative medicine may offer novel strategies to treat patients with end-stage organ failure. The ultimate aim of cell transplantation, tissue engineering, and stem cells is to regenerate tissues and organs. With the development of whole organ decellularization methods, the equation of organ shortage may dramatically change in the near future. Decellularized organs provide the ideal transplantable scaffold with all the necessary microstructure and extracellular cues for cell attachment, differentiation, vascularization, and function. New techniques to re-engineer organs may have major implications for the fields of drug discovery, regeneration biology, and ultimately organ transplantation. In this review we have provided an overview of complementary approaches to study and enhance the success of organ repopulation strategies creating new grafts/organs for transplantation.

    Esquivel, Carlos O.; Iwatsuki, Shunzaburo; Gordon, Robert D.; Marsh, Wallis W.; Koneru, Baburao; Makowka, Leonard; Tzakis, Andreas G.; Todo, Satoru; Starzl, Thomas E.


    Two hundred fifty pediatric (<18 years of age) patients underwent orthotopic liver transplantation because of end-stage liver disease and were given combination therapy with cyclosporine and prednisone. The most common indications for transplantation In decreasing order of frequency were biliary atresia, inborn errors of metabolism, and postnecrotic cirrhosis. The 5-year actuarial survival for the entire group was 69.2%. Age and diagnosis did not influence survival. Infections were the most common cause of death, followed by liver failure and cerebrovascular accident. The impact of retransplantation on survival depends on the indication. The survival is better when retransplantation is carried out after rejection than because of technical complications, and the latter has a better survival than does primary graft nonfunction. The difference in survival among these groups is statistically significant. The quality of life for 164 of 173 survivors is good to excellent; only nine children are currently experiencing medical problems. A persisent problem in pediatric transplantation is the scarcity of small donors. PMID:3316578

    Burra, Patrizia; Germani, Giacomo


    Non-alcoholic fatty liver disease (NAFLD) is a frequent etiology of liver disease in Western Countries and non-alcoholic steato-hepatitis (NASH) is becoming a leading indication for liver transplantation in US, with constant increase overtime. Specific co-morbidities correlated to the presence of obesity and associated with metabolic syndrome should always be ruled out in patients affected by NASH-related end-stage liver disease, who are potential candidates for liver transplantation. Patients transplanted for NAFLD present similar outcomes compared with patients transplanted for other indications. With regards to post-transplant outcomes in obese patients, available data are contradictory, with reported increased mortality only in patients with BMI >40. A new multidisciplinary protocol of liver transplantation and sleeve gastrectomy seems to be effective and safe in obese patients who were not able to lose weight before liver transplantation. However prospective studies are needed. The NASH recurrence rate after liver transplantation ranges between 20-40%, but its variability largely depends on the methodology used for the diagnosis (i.e. liver tests, liver histology or imaging technique).

    After having experienced more than 2,000 cases of adult living donor liver transplantation (LDLT), we established the concepts of right liver graft standardization. Right liver graft standardization intends to provide hemodynamics-based and regeneration-compliant reconstruction of vascular inflow and outflow. Right liver graft standardization consists of the following components: Right hepatic vein reconstruction includes a combination of caudal-side deep incision and patch venoplasty of the graft right hepatic vein to remove the acute angle between the graft right hepatic vein and the inferior vena cava; middle hepatic vein reconstruction includes interposition of a uniform-shaped conduit with large-sized homologous or prosthetic grafts; if the inferior right hepatic vein is present, its reconstruction includes funneling and unification venoplasty for multiple short hepatic veins; if donor portal vein anomaly is present, its reconstruction includes conjoined unification venoplasty for two or more portal vein orifices. This video clip that shows the surgical technique from bench to reperfusion was a case presentation of adult LDLT using a modified right liver graft from the patient's son. Our intention behind proposing the concept of right liver graft standardization is that it can be universally applicable and may guarantee nearly the same outcomes regardless of the surgeon's experience. We believe that this reconstruction model would be primarily applied to a majority of adult LDLT cases.

    With the advances in technical skills,management of postoperative complications and improvements in immunosuppressive drugs,liver transplantation is the standard treatment for many patients with chronic liver disease.Today,shortage of donor organs seems to be the major limiting factor for the application of liver transplantation.This review focuses on five issues that are challenging to clinical practice of liver transplantation and relevant to gastroenterologists.These include living donor liver transplantation,recurrent viral hepatitis,non-heart-beating donors,hepatocellular carcinoma,and ABO incompatible livertransplantation.Living donor and non-heart beating donor transplantations were initiated as a solution to increase the donor organ pool and it is expected that there will be an increase in the number of these donors.Recurrent hepatitis C and hepatocellular carcinoma following liver transplantation are among major problems and ongoing research in these diseases may lead to better outcomes in these recipients.

    Liver transplantation(LT) has become the standard of care for patients with end stage liver disease. The allocation of organs, which prioritizes the sickest patients, has made the management of liver trans-plant candidates more complex both as regards their comorbidities and their higher risk of perioperative complications. Patients undergoing LT frequently display considerable physiological changes during the pro-cedures as a result of both the disease process and the surgery. Transoesophageal echocardiography(TEE), which visualizes dynamic cardiac function and overall contractility, has become essential for perioperative LT management and can optimize the anaesthetic management of these highly complex patients. More-over, TEE can provide useful information on volume status and the adequacy of therapeutic interventions and can diagnose early intraoperative complications, such as the embolization of large vessels or development of pulmonary hypertension. In this review, directed at clinicians who manage TEE during LT, we show why the procedure merits a place in challenging anaesthetic environment and how it can provide essential information in the perioperative management of compromised patients undergoing this very complex surgical procedure.

    The main goal of 2-stage liver transplant is to provide time to obtain a new liver source. We describe our experience of 3 patients with 3 different clinical conditions. A 57-year-old man was retransplanted successfully with this technique due to hepatic artery thrombosis. However, a 38-year-old woman with fulminant toxic hepatitis and a 5-year-old-boy with abdominal trauma had poor outcome. This technique could serve as a rescue therapy for liver transplant patients who have toxic liver syndrome or abdominal trauma. These patients required intensive support during long anhepatic states. The transplant team should decide early whether to use this technique before irreversible conditions develop.

    A previous study has shown that liver or combined liver-kidney transplantation can be a valuable surgical technique for the treatment of polycystic liver disease.Herein, we present the case of a 35-year-old woman with polycystic liver disease, who underwent orthotopic liver transplantation (OLT) on November 11, 2008.The whole-size graft was taken from a deceased donor (a 51-year-old man who died of a heart attack).Resection in a patient with massive hepatomegaly is very difficult. Thus, after intercepting the portal hepatic vein, left hepatectomy was performed, then the vena cava was intercepted, the second and third porta hepatic isolated, and finally, right hepatectomy was performed. OLT was performed successfully.The recipient did well after transplantation. This case suggested that OLT is an effective therapeutic option for polycystic liver disease and left hepatectomy can be performed first during OLT if the liver is over enlarged.

  16. Competition in liver transplantation: helpful or harmful? (United States)

    Saidi, Reza F; Razavi, Moaven; Cosimi, A Benedict; Ko, Dicken S C


    Improved outcomes of liver transplantation have led to increases in the numbers of US transplant centers and candidates on the list. The resultant and ever-expanding organ shortage has created competition among centers, especially in regions with multiple liver transplant programs. Multiple reports now document that competition among the country's transplant centers has led to the listing of increasingly high-risk patients and the utilization of more marginal liver allografts.

    Mendoza-Sánchez, Federico; Javier-Haro, Francisco; Mendoza-Medina, Diego Federico; González-Ojeda, Alejandro; Cortés-Lares, José Antonio; Fuentes-Orozco, Clotilde

    Liver transplantation in patients with liver cirrhosis, portal vein thrombosis, and cavernous transformation of the portal vein, is a complex procedure with high possibility of liver graft dysfunction. It is performed in 2-19% of all liver transplants, and has a significantly high mortality rate in the post-operative period. Other procedures to maintain portal perfusion have been described, however there are no reports of liver graft perfusion using right gastroepiploic vein. A 20 year-old female diagnosed with cryptogenic cirrhosis, with a Child-Pugh score of 7 points (class "B"), and MELD score of 14 points, with thrombosis and cavernous transformation of the portal vein, severe portal hypertension, splenomegaly, a history of upper gastrointestinal bleeding due to oesophageal varices, and left renal agenesis. The preoperative evaluation for liver transplantation was completed, and the right gastroepiploic vein of 1-cm diameter was observed draining to the infrahepatic inferior vena cava and right suprarenal vein. An orthotopic liver transplantation was performed from a non-living donor (deceased on January 30, 2005) using the Piggy-Back technique. Portal vein perfusion was maintained using the right gastroepiploic vein, and the outcome was satisfactory. The patient was discharged 13 days after surgery. Liver transplantation was performed satisfactorily, obtaining an acceptable outcome. In this case, the portal perfusion had adequate blood flow through the right gastroepiploic vein.

  18. Neurologic complications of liver transplantation. (United States)

    Martinez, A J; Estol, C; Faris, A A


    The clinical and neuropathologic findings of 55 adults and 30 children who received liver transplants were reviewed. Encephalopathy was the most common clinical neurologic syndrome and was usually caused by metabolic or anoxic causes. (Alzheimer type astrocytes were present in 73 per cent of patients, and evidence of diffuse hypoxic damage was present in 40 per cent of children and 25 per cent of adults.) Cerebrovascular lesions were a common finding with infarcts or hemorrhages present in 30 per cent of patients. CNS infections were documented in 34 per cent of patients. Seizures were present in a third of patients. Central pontine myelinolysis was present in 12 per cent of patients and was more common in adults than in children. Antemortem diagnosis of neurologic complications was more often based on clinical presentation rather than specific radiologic or laboratory tests.

    Liver transplantation offers excellent results for children with end-stage liver disease, and efforts should be directed toward maintaining long-term graft health. We evaluate graft pathology in healthy pediatric transplant recipients with low-maintenance immunosuppressive medications to assess whether protocol biopsies are helpful for adapting immunosuppression and protecting long-term graft function. Liver biopsies were performed on 60 healthy pediatric liver transplant recipients, and histological findings were correlated with laboratory, serological, and radiological results. Fourteen patients (23%) were diagnosed with acute or early chronic rejection, and immunosuppressive medications were increased in these children. Liver function tests did not correlate with histological findings. The incidence of fibrosis was 36% in transplant recipients five or more years after liver transplantation. We observed an unexpectedly high prevalence of rejection and fibrosis in children with no laboratory abnormalities, which led to changes in their immunosuppressive medications. Scheduled biopsies appear to be useful in pediatric transplant recipients with low immunosuppressive medications for early detection of morphological changes in liver transplants. Further studies are needed to evaluate whether adaption of immunosuppression helps to reduce tissue damage and the incidence of allograft dysfunction in the long term.

  1. Two cases of combined liver-kidney transplantation

    Institute of Scientific and Technical Information of China (English)


    Objectives To report the clinical experiences of srmultaneous hepatorenal transplantation. Methods We performed simultaneous hepatorenal transplantation in one patient with liver cirrhosis of hepatitis B and uremia of chronic nephritis on February 1,1999 and one patient with liver cirrhosis of hepatitis B complicated by hepatorenal syndrome on March 12, 1999.The donors were heart arrest cases. Rapid multiple organ harvesting techniques and UW solution infusion in situ were used. Liver and kidney transplantation were orthotopic and ordinary methods, respectively. Immunosuppressive drugs consisted of cyclosporine, Cellcept, ALG and sortstso steroids. Lamividine was used os day 50 and day 40 postoparation, respectively. Results Both transplanted organs rapidly achieved normal function postoperation and the patients recovered well but suffered mild kidney rejection day 110 postopemtion in No 1 patient. In No 2 patient, acute renal function failure, mental symptoms, muscle spasm,cerebral artery thrombosis, inhalation poeumonia and chronic liver graft rejection ensured sequentially but were controlled.The patients have survived for more than nine and eight months, respectively, with normal life quality. Conclusions Combined hepatorenal transplant is a radical treatment method for liver and kidney function failure and requires more comprehensive techniques than isolated single organ transplantation.Preventing the recurrence of hepatitis B by oral lamividine may be a kdy to long-term survival.

    The disbalance between the number of candidates to liver transplant and the number of liver grafts leads to waiting list mortality. Two potential ways of increasing the number of liver grafts are split liver transplantation and the transplantation of grafts from non-heart beating donors. Both of them were discussed in a consensus meeting of the Spanish Society of Liver Transplantation in October 2012. This paper outlines the conclusions of that meeting.

  3. Recurrent hepatitis C after liver transplant. (United States)

    deLemos, Andrew S; Schmeltzer, Paul A; Russo, Mark W


    End stage liver disease from hepatitis C is the most common indication for liver transplantation in many parts of the world accounting for up to 40% of liver transplants. Antiviral therapy either before or after liver transplantation is challenging due to side effects and lower efficacy in patients with cirrhosis and liver transplant recipients, as well as from drug interactions with immunosuppressants. Factors that may affect recurrent hepatitis C include donor age, immunosuppression, IL28B genotype, cytomegalovirus infection, and metabolic syndrome. Older donor age has persistently been shown to have the greatest impact on recurrent hepatitis C. After liver transplantation, distinguishing recurrent hepatitis C from acute cellular rejection may be difficult, although the development of molecular markers may help in making the correct diagnosis. The advent of interferon free regimens with direct acting antiviral agents that include NS3/4A protease inhibitors, NS5B polymerase inhibitors and NS5A inhibitors holds great promise in improving outcomes for liver transplant candidates and recipients.

    BACKGROUND:Calcineurin inhibitor-related renal toxicity affects patient and graft survival in transplant recipients. This study aimed to determine whether sirolimus is effective and safe in treating renal insufifciency related to tacrolimus after liver transplantation. METHODS: Tacrolimus for primary immunosuppression was used in 16 patients after liver transplantation. Patients with a creatinine level higher than 132.6μmol/L were eligible for conversion to sirolimus. Simultaneously, the dose of tacrolimus was decreased to half. Blood urea nitrogen, creatinine, tacrolimus level, liver function and rejection episodes were monitored dynamically. RESULTS:All patients showed improvement of renal function after conversion to sirolimus. Blood creatinine level was reduced from 146.8±92.4 to 105.3±71.3μmol/L (P CONCLUSION:Sirolimus can be safely used in liver transplant recipients suffering from tacrolimus-related renal insufifciency.

  6. [Schizophrenia and Liver Transplantation: Case Report]. (United States)

    Diana, Restrepo B; Marle, Duque G; Carlos, Cardeño C


    Liver transplantation is a treatment available for many patients with liver cirrhosis who find in this treatment a way to improve life expectancy and quality of life. Paranoid schizophrenia affects 1% of the general population, produces psychotic symptoms, and runs a chronic course in some cases with significant deterioration in all areas of life. To discuss the case of a patient with liver cirrhosis diagnosed with paranoid schizophrenia during the evaluation protocol for liver transplantation. Case report. We report the case of a 47-year-old woman with liver cirrhosis whose only alternative to improve life expectancy and quality of life was access to liver transplantation. During routine evaluations the liaison psychiatrist observed first-order psychotic symptoms and documented a life story that confirmed the presence of paranoid schizophrenia. Paranoid schizophrenia is a psychiatric disorder common in the general population that can be a part of the medical comorbidities of patients requiring liver transplantation and is not an absolute contraindication to its completion. We are unaware of similar cases of liver transplantation in patients with schizophrenia in our country. We believe this is a big step on the road to overcome the stigma that mental illness imposes on patients. Copyright © 2012 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

  7. Central nervous system complications after liver transplantation. (United States)

    Kim, Jeong-Min; Jung, Keun-Hwa; Lee, Soon-Tae; Chu, Kon; Roh, Jae-Kyu


    We investigated the diversity of central nervous system complications after liver transplantation in terms of clinical manifestations and temporal course. Liver transplantation is a lifesaving option for end stage liver disease patients but post-transplantation neurologic complications can hamper recovery. Between 1 January 2001 and 31 December 2010, patients who had undergone liver transplantation at a single tertiary university hospital were included. We reviewed their medical records and brain imaging data and classified central nervous system complications into four categories including vascular, metabolic, infectious and neoplastic. The onset of central nervous system complications was grouped into five post-transplantation intervals including acute (within 1 month), early subacute (1-3 months), late subacute (3-12 months), chronic (1-3 years), and long-term (after 3 years). During follow-up, 65 of 791 patients (8.2%) experienced central nervous system complications, with 30 occurring within 1 month after transplantation. Vascular etiology was the most common (27 patients; 41.5%), followed by metabolic (23; 35.4%), infectious (nine patients; 13.8%), and neoplastic (six patients). Metabolic encephalopathy with altered consciousness was the most common etiology during the acute period, followed by vascular disorders. An initial focal neurologic deficit was detected in vascular and neoplastic complications, whereas metabolic and infectious etiologies presented with non-focal symptoms. Our study shows that the etiology of central nervous system complications after liver transplantation changes over time, and initial symptoms can help to predict etiology.

  8. Iatrogenic amyloid polyneuropathy after domino liver transplantation. (United States)

    Mnatsakanova, Diana; Živković, Saša A


    Liver transplantation has been used in treatment of transthyretin amyloidosis, and some patients undergo domino liver transplantation (DLT) with explanted liver being transplanted to another patient with liver failure as the liver is otherwise usually functionally normal. Until end of 2015, there were 1154 DLT performed worldwide. DLT for transthyretin amyloidosis is associated with the risk of developing de novo systemic amyloidosis and amyloid neuropathy, and the risk may be greater with some non-Val30Met mutations. De novo amyloid neuropathy has been described in up to 23% of transplant recipients. Neuropathy may be preceded by asymptomatic amyloid deposition in various tissues and symptoms of neuropathy started after a median of 7 years following DLT (5.7 ± 3.2 years; range 2 mo to 10 years). Typical initial symptoms include neuropathic pain and sensory loss, while dysautonomia usually starts later. Progression of neuropathy may necessitate liver re-transplantation, and subsequent improvement of neuropathy has been reported in some patients. Explant allograft recipients need close monitoring for signs of systemic amyloidosis, neuropathy and dysautonomia as progressive symptoms may require re-transplantation.

  9. Liver Transplantation: Past Accomplishments and Future Challenges

    Directory of Open Access Journals (Sweden)

    William J Wall


    Full Text Available Liver transplantation has evolved from a rare and risky operation of questionable therapeutic value to the preferred treatment for an extensive list of end-stage liver diseases. Superior immunosuppression (cyclosporine, and improvements in surgery and anesthesia brought liver grafting to its current level of success. Nearly 60,000 liver transplants have been performed, and survival rates are very good; however liver grafting faces serious immediate and long term challenges, mainly due to the widening gap between donor supply and recipient demand. Increasing numbers of sick candidates, recurrent disease (especially hepatitis C and recidivism rates after transplantation for alcoholic cirrhosis will force increasingly difficult decisions on candidate selection and priority listing of potential recipients. Although xenotransplantation may be the ultimate solution, it has its own specific set of biological and societal challenges - the full extent of which should be revealed in the next several years.

    Stock, P G; Estrin, J A; Fryd, D S; Payne, W D; Belani, K G; Elick, B A; Najarian, J S; Ascher, N L


    The purpose of this study was to analyze data from all adult and pediatric liver transplants performed between January 1, 1983 and January 15, 1986 at the University of Minnesota Hospital and identify perioperative variables that predict patient survival and could aid in patient selection. Charts, intraoperative anesthesia records, blood bank records, flow sheets, outpatient records, and autopsy reports were examined in 45 pediatric and 15 adult patients who underwent primary orthotopic liver transplantation. Analysis of the data can be summarized as follows: (1) Pediatric patients whose coagulation parameters could not be corrected prior to operation and who consequently required preoperative exchange transfusion had poorer outcomes than those not requiring an exchange to correct coagulation parameters. (2) The rapid infusion technique for massive blood transfusion resulted in significantly decreased blood loss and intraoperative blood product replacement. (3) Twenty-four hour postoperative factor V levels were good predictors of survival. Patients with poor factor V levels required rigorous replacement of coagulation factors. (4) Pediatric patients with uncorrectable coagulopathies requiring immediate postoperative exchange transfusion had extremely high mortality.

    It is well-known that 30% of the remaining liver mass, following partial hepatectomy, regenerates to full original mass within 2 weeks in rats. In order to carry the transplanted rat liver to repeated transplantation, a technique of combining 30% of the liver with the pancreaticoduodenum and spleen transplantation is performed in this consecutive organ transplantation study. Our laboratory observed several 37-month-old transplanted rats by carrying through 2-3 generations, and histological disclosure were made. Because the partial liver transplants did not regenerate after the transplantation with other splanchnic organs, this technique is not so difficult though subsequent surgical maneuvers are needed and the liver histology proved entirely normal in every aspect when followed beyond the rat's life span of 24 months.

    Neumann, U P; Neuhaus, P; Schmeding, M


    The worldwide shortage of adequate donor organs implies that living donor liver transplantation represents a valuable alternative to cadaveric transplantation. In addition to the complex surgical procedure the correct identification of eligible donors and recipients plays a decisive role in living donor liver transplantation. Donor safety must be of ultimate priority and overrules all other aspects involved. In contrast to the slightly receding numbers in Europe and North America, in recent years Asian programs have enjoyed constantly increasing living donor activity. The experience of the past 15 years has clearly demonstrated that technical challenges of both bile duct anastomosis and venous outflow of the graft significantly influence postoperative outcome. While short-term in-hospital morbidity remains increased compared to cadaveric transplantation, long-term survival of both graft and patient are comparable or even better than in deceased donor transplantation. Especially for patients expecting long waiting times under the MELD allocation system, living donor liver transplantation offers an excellent therapeutic alternative. Expanding the so-called "Milan criteria" for HCC patients with the option for living donor liver transplantation is currently being controversially debated.

  17. Perioperative nutritional therapy in liver transplantation. (United States)

    Hammad, Ahmed; Kaido, Toshimi; Uemoto, Shinji


    Protein-energy malnutrition is frequently seen in patients with end-stage liver disease who undergo liver transplantation. This causes a deterioration of the patients' clinical condition and affects their post-transplantation survival. Accurate assessment of the nutritional status and adequate intervention are prerequisites for perioperative nutritional treatment. However, the metabolic abnormalities induced by liver failure make the traditional assessment of the nutritional status difficult. The methods that were recently developed for accurately assessing the nutritional status by body bioelectrical impedance may be implemented in pre-transplant management. Because preoperative malnutrition and the loss of skeletal muscle mass, called sarcopenia, have a significant negative impact on the post-transplantation outcome, it is essential to provide adequate nutritional support during all phases of liver transplantation. Oral nutrition is preferred, but tube enteral nutrition may be required to provide the necessary caloric intake. We herein discuss both bioelectrical impedance and the latest findings in the current perioperative nutritional interventions in liver transplant patients regarding synbiotics, micronutrients, branched-chain amino acid supplementation, the use of immune system modulating formulas, the fluid balance and the offering of nocturnal meals.

    Objective To study the effects of liver specific antigen (LSA) on liver allotransplantation rejection. Methods Orthotopic liver transplantation was performed in this study. Group Ⅰ: syngeneic control (Wistar-to-Wistar); Group Ⅱ: acute rejection (SD-to-Wistar). Group Ⅲ: thymic inoculation of SD rat LSA day 7 before transplantation. The observation of general condition and survival time, rejection grades and the NF-κB activity of splenocytes were used to analyze severity of acute rejection and immune state of animals in different groups. Results The general condition of group Ⅰ was fair post transplantation with no sign of rejection. All recipients of group Ⅱ died within days 9 to 13 post transplantation with median survival time of 10.7 ±1.37 days. As for group Ⅲ, 5 out of 6 recipients survived for a long period with remarkably better general condition than that of group Ⅱ. Its rejection grades were significantly lower than group Ⅱ (P< 0.05).NF-κB activity was only detected in group Ⅰ between days 5 and 7 after transplantation, whereas high activity of NF-κB was detected at all points in group Ⅱ and low NF-κB activity was detected in group Ⅲ which was significantly lower than that of group Ⅱ (P < 0.05). Conclusions LSA is an important transplantation antigen directly involved in the immunorejection of liver transplantation. Intrathymic inoculation of LSA can alleviate the rejection of liver allotransplantation,grafts survive for a period of time thereby, allowing a novel way to liver transplantation immunotolerance.

    Liver disease alters the glucose metabolism and may cause diabetes, but this condition is potentially reversible with liver transplantation (LTx). Type 1 diabetes mellitus may be coincidentally present in a LTx candidate and immunosuppressive drugs will aggravate diabetes and make its management more difficult for posttransplant. In addition, diabetes negatively influences outcome after LTx. Therefore, the question arises as to why not transplanting the pancreas in addition to the liver in selected patients suffering from both liver disease and Type 1 diabetes. We report two cases of en bloc combined liver and pancreatic transplantation, a technique originally described a decade ago in the treatment of upper abdominal malignancies but rarely used for the treatment of combined liver disease and Type 1 diabetes. Both recipients are currently liver disease-free and insulin-free more than 2 and 4 years posttransplant, respectively. Surgical, medical and immunological aspects of combined liver-pancreas transplantation are discussed in the light of the existing relevant literature.

    Appendicitis is a common cause of emergency surgery that in the population undergoing organ transplantation presents a rare incidence due to late diagnosis and treatment. To report the occurrence of acute appendicitis in a cohort of liver transplant recipients. Retrospective analysis in a period of 12 years among 925 liver transplants, in witch five cases of acute appendicitis were encountered. Appendicitis occurred between three and 46 months after liver transplantation. The age ranged between 15 and 58 years. There were three men and two women. The clinical presentations varied, but not discordant from those found in non-transplanted patients. Pain was a symptom found in all patients, in two cases well located in the right iliac fossa (40%). Two patients had symptoms characteristic of peritoneal irritation (40%) and one patient had abdominal distention (20%). All patients were submitted to laparotomies. In 20% there were no complications. In 80% was performed appendectomy complicated by suppuration (40%) or perforation (40%). Superficial infection of the surgical site occurred in two patients, requiring clinical management. The hospital stay ranged from 48 h to 45 days. Acute appendicitis after liver transplantation is a rare event being associated with a high rate of drilling, due to delays in diagnosis and therapy, and an increase in hospital stay.

  2. Human herpesvirus 6 infections after liver transplantation

    Institute of Scientific and Technical Information of China (English)

    Rima Camille Abdel Massih; Raymund R Razonable


    Human herpesvirus 6 (HHV-6) infections occur in > 95% of humans. Primary infection, which occurs in early childhood as an asymptomatic illness or manifested clinically as roseola infantum, leads to a state of subclinical viral persistence and latency. Reactivation of latent HHV-6 is common after liver transplantation, possibly induced and facilitated by allograft rejection and immunosuppressive therapy. Since the vast majority of humans harbor the virus in a latent state, HHV-6 infections after liver transplantation are believed to be mostly due to endogenous reactivation or superinfection (reactivation in the transplanted organ). In a minority of cases, however,primary HHV-6 infection may occur when an HHV-6 negative individual receives a liver allograft from an HHV-6 positive donor. The vast majority of documented HHV-6 infections after liver transplantation are asymptomatic. In a minority of cases, HHV-6 has been implicated as a cause of febrile illness with rash and myelosuppression, hepatitis, pneumonitis, and encephalitis after liver transplantation. In addition,HHV-6 has been associated with a variety of indirect effects such as allograft rejection, and increased predisposition and severity of other infections including cytomegalovirus (CMV), hepatitis C virus, and opportunistic fungi. Because of the uncommon nature of the clinical illnesses directly attributed to HHV-6, there is currently no recommended HHV-6- specific approach to prevention. However, ganciclovir and valganciclovir, which are primarily intended for the prevention of CMV disease, are also active against HHV-6 and may prevent its reactivation after transplantation. The treatment of established HHV-6 disease is usually with intravenous ganciclovir, cidofovir,or foscarnet, complemented by reduction in the degree of immunosuppression. This article reviews the current advances in the pathogenesis, clinical diagnosis, and therapeutic modalities against HHV6 in the setting of liver transplantation.

    Proteinuria is a manifestation of renal dysfunction and it has been demonstrated to be a significant prognostic factor in various clinical situations. The study was designed to analyze prognosis of patients receiving liver transplantation as well as to determine predictive performance of perioperative proteinuria. We retrospectively reviewed data of patients who had received a liver transplant in a medical center between 2002 and 2010. Demographic information and clinical characteristic parameters were recorded on the day of intensive care unit admission before operation and on postoperative days 1, 7, and 14. Among a total of 323 patients, in-hospital mortality and 90-day mortality rates were 13.0 % (42/323) and 14.2 % (46/323), respectively. Patients with proteinuria on admission had higher rates of acute kidney injury (26.8 % vs. 8.8 %, p proteinuria on admission and Sequential Organ Failure Assessment (SOFA) score were independent predictors of in-hospital mortality. The discriminatory ability of proteinuria plus SOFA was even better than that of SOFA alone, especially on postoperative day 1. The presence of proteinuria before liver transplantation is supposed to be recognized as a negative predictor for in-hospital survival. Moreover, the presence of proteinuria after liver transplantation can assist in the early prediction of poor short-term prognosis for patients receiving liver transplantation.

    Marco Carbone


    Full Text Available End-stage liver disease due to hepatitis C (HCV and cirrhosis from alcohol (ALD are the commonest indications for liver transplantation in the western countries. Up to one third of HCV-infected transplant candidates have a history of significant alcohol intake prior to transplantation. However, there are few data available about the possible interaction between alcohol and HCV in the post-transplant setting. Patients with both HCV and alcohol are more likely to die on the waiting list than those with ALD and HCV alone. However, after transplantation, non-risk adjusted graft and patient survival of patients with HCV + ALD are comparable to those of patients with HCV cirrhosis or ALD cirrhosis alone. In the short and medium term HCV recurrence after transplant in patients with HCV + ALD cirrhosis does not seem more aggressive than that in patients with HCV cirrhosis alone. A relapse in alcohol consumption in patients with HCV + ALD cirrhosis does not have a major impact on graft survival. The evidence shows that, as is currently practiced, HCV + ALD as an appropriate indication for liver transplantation. However, these data are based on retrospective analyses with relatively short follow-up so the conclusions must be treated with caution.

  6. Using old liver grafts for liver transplantation: where are the limits? (United States)

    Jiménez-Romero, Carlos; Caso Maestro, Oscar; Cambra Molero, Félix; Justo Alonso, Iago; Alegre Torrado, Cristina; Manrique Municio, Alejandro; Calvo Pulido, Jorge; Loinaz Segurola, Carmelo; Moreno González, Enrique


    The scarcity of ideal liver grafts for orthotopic liver transplantation (OLT) has led transplant teams to investigate other sources of grafts in order to augment the donor liver pool. One way to get more liver grafts is to use marginal donors, a not well-defined group which includes mainly donors > 60 years, donors with hypernatremia or macrosteatosis > 30%, donors with hepatitis C virus or hepatitis B virus positive serologies, cold ischemia time > 12 h, non-heart-beating donors, and grafts from split-livers or living-related donations. Perhaps the most practical and frequent measure to increase the liver pool, and thus to reduce waiting list mortality, is to use older livers. In the past years the results of OLT with old livers have improved, mainly due to better selection and maintenance of donors, improvements in surgical techniques in donors and recipients, and intra- and post-OLT management. At the present time, sexagenarian livers are generally accepted, but there still exists some controversy regarding the use of septuagenarian and octogenarian liver grafts. The aim of this paper is to briefly review the aging process of the liver and reported experiences using old livers for OLT. Fundamentally, the series of septuagenarian and octogenarian livers will be addressed to see if there is a limit to using these aged grafts.

  7. Thoracic radiology in kidney and liver transplantation. (United States)

    Fishman, Joel E; Rabkin, John M


    Renal transplantation accounts for more than half of all solid organ transplants performed in the U.S., and the liver is the second most commonly transplanted solid organ. Although abdominal imaging procedures are commonplace in these patients, there has been relatively little attention paid to thoracic imaging applications. Preoperative imaging is crucial to aid in the exclusion of infectious or malignant disease. In the perioperative time period, thoracic imaging focuses both on standard intensive care unit care, including monitoring devices and their complications, and on the early infections that can occur. Postoperative management is divided into three time periods, and the principles governing the occurrence of infections and malignancies are reviewed. Anatomic and pathologic aspects unique to kidney and liver transplantation patients are also discussed.

  8. Colonic Malakoplakia in a Liver Transplant Recipient

    Directory of Open Access Journals (Sweden)

    Peter TW Kim


    Full Text Available Malakoplakia is a rare inflammatory condition seen in transplant patients. There are two previously reported cases of malakoplakia involving the gastrointestinal tract in liver transplant patients. The present paper reports a case of colonic malakoplakia in a 58-year-old woman, a liver transplant recipient who was receiving immunosuppressive drugs. She presented with chronic diarrhea while on tacrolimus. There was no history of antecedent infection. Colonoscopy showed patchy mucosal edema, but no discrete yellow plaques or nodules. The diagnosis was made by colon biopsies, which showed chronic inflammation with many histiocytes containing Michaelis-Gutmann bodies. Although rare, malakoplakia is one of many potential causes of diarrhea in a transplant patient. The present case indicates that malakoplakia may be associated with chronic diarrhea, even if there are no macroscopic lesions seen during colonoscopy.

    Full Text Available Liver or hepatic transplantation (LT is the replacement of a diseased liver with part or whole healthy liver from another person (allograft. Human liver transplants were first performed by Thomas Starzl in the United States and Roy Calne in Cambridge, England in 1963 and 1967, respectively. Liver transplantation is a viable treatment option for end-stage liver disease and acute liver failure. Pediatric patients account for about 12.5% of liver transplant recipients. The most commonly used technique is orthotopic transplantation, in which the native liver is removed and replaced by the donor organ in the same anatomic location as the original liver. Cirrhosis, or liver injury, is a common reason why adults need liver transplants and children with bile duct disease issues are often the candidates. Survival statistics depend greatly on the age of donor, age of recipient, skill of the transplant center, compliance of the recipient, whether the organ came from a living or cadaveric donor and overall health of the recipient. Survival rates improve almost yearly, due to improved techniques and medications.

    Selective cyclooxygenase-2 (COX-2) inhibitors are widely used due to their efficacy and good safety profile.However, recent case reports have described varying degrees of liver injuries associated with the use of COX-2 inhibitors. We report the case of a patient who developed acute cholestatic hepatitis progressing to hepatic failure requiring liver transplantation, following a 3-d course of celecoxib for treatment of generalized muscle aches and pains. The clinical presentation, the laboratory data, as well as the liver histopathology were supportive of the putative diagnosis of drug induced liver injury.

    Eight adults and 3 children out of 85 patients who had neuropathologic examination after death following orthotopic liver transplantation showed central pontine myelinolysis (CPM). Four patients also had extrapontine myelinolysis. Eight patients had significant serum sodium changes. In 5, the fluctuation occurred perioperatively and 4 had a clinical picture consistent with CPM, although no patient had this as an antemortem diagnosis. We emphasize the role of hepatic dysfunction as a cause of CPM and recommend careful monitoring of electrolytes in the perioperative period of patients undergoing liver transplantation.

    See Ching Chan; Sheung Tat Fan


    Living donor liver transplantation (LDLT) has gone through its formative years and established as a legitimate treatment when a deceased donor liver graft is not timely or simply not available at all. Nevertheless,LDLT is characterized by its technical complexity and ethical controversy. These are the consequences of a single organ having to serve two subjects, the donor and the recipient, instantaneously. The transplant community has a common ground on assuring donor safety while achieving predictable recipient success. With this background, a reflection of the development of LDLT may be appropriate to direct future research and patient- care efforts on this life-saving treatment alternative.

    BACKGROUND: The safety and possibility of pregnancy following liver transplantation has been the hot topic in transplant. A case is reported with a review the of literature. METHOD: The data of a 22-year-old pregnant patient with end-stage liver disease who had undergone orthotopic liver transplantation in September 28, 2000 were analyzed retrospectively. RESULTS: After surgery, the patient was uneventfully recovered and was pregnant at the time of the 33rd month postoperation. The patient experienced a rejection on the 8th week of pregnancy and was successfully treated at this hospital. The patient was closely monitored throughout her pregnancy, and received routine antenatal care with respect to sonographic screening. Caesarean section was performed in March 18, 2004, and a health live-born infant weighing 2000 g was delivered at full-term. After the delivery, the patient was satisfactory with her health and the baby was healthy. CONCLUSION:Under close monitoring, successful pregnancy following liver transplantation is possible and safe in women with end-stage liver diseases.

    BACKGROUND: Liver transplantation can lead to the develop-ment of posttraumatic stress disorder (PTSD), but the risk factors associated with this progression are not well understood. To study this syndrome in adult liver transplant recipients, a cross-sectional investigation of 296 recipients at our hospital was carried out between January and June 2010. METHODS: Study participants completed two questionnaires [a PTSD self-rating scale (PTSD-SS) and a validated Chinese version of the Medical Outcomes Study Short Form-36 (SF-36)]. Clinical and demographic data were collected from the records of the Chinese Liver Transplant Registry and via questionnaires. RESULTS: The prevalence of full PTSD and partial PTSD (that met the criteria for 2 of the 3 symptom clusters) was 3.7% and 5.4%, respectively, for all transplant recipients. Significant differences between the recipients with no PTSD, partial PTSD, and full PTSD were found in all SF-36 domains except for physical functioning (P=0.466). In general, domain scores were the highest in the recipients who did not meet the criteria for PTSD and the lowest in the recipients who met the criteria for full PTSD. Greater severity of posttraumatic stress symptoms was correlated with poorer quality of life, especially in the bodily pain (P=0.004), social functioning (P=0.001), role-emotional (P=0.048), and mental health (P<0.001) domains. The model for end-stage liver disease (MELD) scores, complications, and educational status were identified by multiple regression analysis as risk factors for developing PTSD. CONCLUSIONS: PTSD occurred after liver transplantation and was significantly associated with decreased quality of life. Higher MELD scores and complications after transplantation were risk factors that contributed to PTSD, and higher education was a protective factor.

    The decision for isolated kidney transplant (KT) vs. combined liver-kidney transplant (CLKT) in patients with end-stage renal disease (ESRD) with compensated cirrhosis remains controversial. We sought to determine outcomes of patients requiring listing for a liver transplant (LT) following either a cadaveric or living donor KT and compare these outcomes to similar patients receiving a CLKT. Our dataset included the United Network for Organ Sharing (UNOS)/Standard Transplant and Analysis and Research (STAR) kidney files from 1987 to 2012 after being joined with the liver files from 2002 to 2012. Outcomes of patients who received a CLKT with an international normalized ratio (INR) ≤1 and total bilirubin ≤1 were compared to patients who received a primary KT and subsequently required listing for LT between zero and five yr or after five yr. For the three groups, 244 patients had a CLKT, 216 were wait-listed for LT between zero and five yr after KT (0-5 WL), and 320 were wait-listed five yr after KT (+5 WL). From the time of KT, the 0-5 WL group had significantly worse survival than the CLKT group and the +5 WL group. The +5 WL had the best survival of all groups. For the 0-5 WL group, 45% underwent LT and 40% died while waiting compared to the +5 WL group with 53% having LT and 26% died while waiting. At the time of LT, the 0-5 WL group had a higher model for end-stage liver disease (MELD) score, higher incidence of being in the ICU at the time of transplant, and higher incidence of requiring life support. From the time of LT, the CLKT trended toward better survival (p = 0.0549) than both the 0-5 WL and +5 WL groups, which had equivalent survival. The 0-5 WL group is a higher risk group with poorer survival due to a higher incidence of dying on the waitlist. Better identification of patients with a high risk for hepatic decompensation following KT and agreement for regional exception for LT in the event of decompensation may improve utilization of organs and

  20. [The role of liver transplantation in clinical practice]. (United States)

    Studeník, P


    The first succesful liver transplantation was made in USA in 1967. These operations had been made only in few centres in the world until the 80-ies of the last century and the results were not so good. However, along with the development of surgical techniques, immunosuppression and postoperational care the results of these operations significantly improved and their amount increased. The liver transplantation was declared the clinical therapy in USA in 1983. In the same year there was made a succesful liver transplantation in Czech republic too. Nowadays there is annually made approximately 10,000 such operations worldwide. During the last decade it is also in Czech republic where the liver transplantation has become an available therapeutic method. There are two workplaces (CKTCH Brno and IKEM Prague) where 70 such operations are made every year. The results of one-year survival are more than 90% and the long-term results and the quality of life of the patients are also very good. The liver transplantation has experienced a dynamic development in the 90-ies of the 20th century and at the edge of the millenium. There were made significant changes in the field of indications and contraindications for transplantation and immunosuppressive therapy. There developed a brand new surgical techniques making possible to use the organs of the donors who are too big, so-called reduction of the implants. Another option constitute so-called split operations when one implant may be divided into left and right lobes and thus each of them may be used separately for the two donees. Due to the significant regeneration ability of the liver tissue it is possible to make the collection of the parts of the liver from the living donor. According to the statistics of the european countries the optimal need should be 10 transplantations/1 million of inhabitants per year. The difference between the need and the real amount of operations in our country is not given by the disability of the

    End-stage liver disease,due to cholestatic liver diseases with an autoimmune background such as primary biliary cirrhosis(PBC)and primary sclerosing cholangitis(PSC),is considered a good indication for liver transplantation.Excellent overall patient and graft outcomes,based mostly on the experience from deceased donor liver ransplantation(DDLT),have been reported.Due to the limited number of oraan donations from deceased donors in most Asian countries,living donor liver transplantation(LDLT)is the mainstream treatment for end-stage liver disease,including that resulting from PBC and PSC.Although the initial experiences with LDLT for PBC and PSC seem satisfactory or comparable to that with DLT,some aspects,including the timing of transplantation,the risk of recurrent disease,and its long-term clinical implications,require further evaluation.Whether or not the long-term outcomes of LDLT from a biologically related donor are equivalent to that of DDLT requires further observations.The clinical course following LDLT may be affected by he genetic background shared between the recipient and the living related donor.(C)2008 The WJG Press.All rights reserved.

    The current role of liver transplantation in treating malignant tumors of the liver is uncertain, except for select histologic types. Pooled data on the results of liver transplantation in 12 children with hepatoblastoma is presented here. One half of the children are alive 24 to 70 (44 +/- 19) months after transplantation with no evidence of recurrence. Three patients (25%) died of tumor recurrence and three (25%) died of other causes. Unifocal and intrahepatic tumors were associated with better prognosis compared to the multifocal tumors and tumors with extrahepatic spread (p = 0.04 and 0.13). Microscopically vascular invasion and the predominance of embryonal and/or anaplastic epithelium were associated with a poor prognosis compared to the tumors with no vascular invasion and with predominantly fetal epithelium (p = 0.08 and 0.1). It is concluded that continued efforts to treat unresectable hepatoblastomas by liver transplantation is justified and the role of adjuvant chemotherapy in improving the results needs to be better defined.

    Full Text Available Liver transplant procedures require the most blood components, despite the fact that blood use in liver transplantation has declined dramatically over the last decade. Liver transplant recipients present unique challenges, not only in terms of blood supply, but also requirements for specialized blood components, serologic problems, and immunologic effects of transfusion on both the allograft and the recipient. The cause of intraoperative blood loss in liver transplantation is multifactorial, due to both technical factors and poor coagulation control. This procedure carries the risk of massive blood loss, which requires massive transfusions and is associated with postoperative infections, reduced graft survival, multi-organ dysfunction, and higher risk of mortality. Efforts to reduce intraoperative bleeding leading to limitation of blood transfusions are desirable to improve results and also to control costs.

    Physicians previously thought that heart disease was rare in patients with end stage liver disease. However, recent evidence shows that the prevalence of ischemic heart disease and cardiomyopathy is increased in transplant candidates compared to most other surgical candidates. Investigators estimate that up to 26% of all liver transplant candidates have at least one critical coronary artery stenosis and that at least half of these patients will die perioperatively of cardiac complications. Cardiomyopathy also occurs in greater frequency. While all patients with advanced cardiac disease have defects in cardiac performance, a larger than expected number of patients have classical findings of dilated, restrictive and hypertropic cardiomyopathy. This may explain why up to 56% of patients suffer from hypoxemia due to pulmonary edema following transplant surgery. There is considerable controversy on how to screen transplant candidates for the presence of heart disease. Questions focus upon, which patients should be screened and what tests should be used. This review examines screening strategies for transplant candidates and details the prognostic value of common tests used to identify ischemic heart disease. We also review the physiological consequences of cardiomyopathy in transplant candidates and explore the specific syndrome of "cirrhotic cardiomyopathy".

    Propylthiouracil- (PTU-) induced hepatotoxicity is rare but potentially lethal with a spectrum of liver injury ranging from asymptomatic elevation of transaminases to fulminant hepatic failure and death. We describe two cases of acute hepatic failure due to PTU that required liver transplantation. Differences in the clinical presentation, histological characteristics, and posttransplant management are described as well as alternative therapeutic options. Frequent monitoring for PTU-induced hepatic dysfunction is strongly advised because timely discontinuation of this drug and implementation of noninvasive therapeutic interventions may prevent progression to liver failure or even death.

    Liver transplantation for patients requiring life-support results in the lowest survival and highest costs. A ten year (1983-1993) regional experience with liver transplantation for critically ill patients was undertaken to ascertain the fate of several subgroups of patients. Of the 828 liver transplants performed at six transplant centers within the region over this period, 168 (20%) were done in patients who met today's criteria for a United Network of Organ Sharing (UNOS) status 1 (emergency) liver transplant candidate. Recipients were classified according to chronicity of disease and transplant number (primary-acute, primary-chronic, reTx-acute, reTx-chronic). Overall one-year survival was 50% for all status 1 recipients. The primary-acute subgroup (n = 63) experienced a 57% one-year survival compared with 50% for the primary-chronic (n = 51) subgroup (P = 0.07). Of the reTx-acute recipients (n = 43), 44% were alive at one year in comparison with 20% for the reTx-chronic (n = 11) group (P = 0.18). There was no significant difference in survival for the following: transplant center, blood group compatibility with donors, age, preservation solution, or graft size. For patients retransplanted for acute reasons (primary graft nonfunction (PGNF) or hepatic artery thrombosis [HAT]), survival was significantly better if a second donor was found within 3 days of relisting (52% vs. 20%; P = 0.012). Over the study period progressively fewer donor organs came from outside the region. No strong survival-based argument can be made for separating, in allocation priority, acute and chronic disease patients facing the first transplant as a status 1 recipient. Clearly patients suffering from PGNF or HAT do far better if retransplanted within 3 days. Establishing an even higher status for recipients with PGNF, perhaps drawing from a supraregional donor pool, would allow surgeons to accept more marginal donors, thus potentially expanding the pool, without significantly

  11. Protective effect of glycine on liver injury during liver transplantation

    Institute of Scientific and Technical Information of China (English)

    @@ Multiple procedures of liver transplantation bring conditions producing cold ischemia-reperfusion (I/R) injury. During cold storage, the graft organ is subjected to cold ischemia, also known as hypoxia injury. After reperfusion, although hypoxic condition has been ameliorated, reoxygenation of the graft liver can produce not only reperfusion injury including generation of oxygen free radical, lipoperoxidation and calcium overload, but also aggravate the hypoxia damage, involving endothelial cell (EC) damage, Kupffer cell (KC) activation, and adherence of neutrophils and platelets to Ecs. Clinically, I/R injury is one of the major problems complicating liver transplantation, and can ultimately result in serious complications such as primary nonfunction and delayed graft function, which may lead to the need of urgent retransplantation. Therefore, the therapeutic strategies of attenuating graft I/R injury are clinically significant and might improve overall graft function and survival.

    The following guideline represents the position of the International Liver Transplantation Society (ILTS) on key preoperative, operative, and postoperative aspects surrounding living liver donation. These recommendations were developed from experts in the field from around the world. The authors conducted an analysis of the National Library of Medicine indexed literature on "living donor liver transplantation" [Medline search] using Grading of Recommendations Assessment, Development and Evaluation methodology. Writing was guided by the ILTS Policy on the Development and Use of Practice Guidelines ( ILTS members, and many more nonmembers, were invited to comment. Recommendations have been based on information available at the time of final submission (March 2016). The lack of randomized controlled trials in this field to date is acknowledged and is reflected in the grading of evidence. Intended for use by physicians, these recommendations support specific approaches to the diagnostic, therapeutic, and preventive aspects of care.

    Non-alcoholic fatty liver disease (NAFLD) seems to recur in at least one third of patients transplanted for non-alcoholic steatohepatitis (NASH)-related cirrhosis. While, NASH recurrence does not seem to affect overall graft and patient survival up to 10 years, cardiovascular and infection-related morbidity and mortality seem to be increased in these patients. This report looks at the graft histology in patients who were transplanted for NASH-related cirrhosis after short-term follow up. We report a high prevalence of recurrent NAFLD in liver grafts post-transplant among five patients. The degree of steatosis noted among the recipients is alarming.

  14. Sclerosing peritonitis and mortality after liver transplantation. (United States)

    Mekeel, Kristin; Moss, Adyr; Reddy, Kunam Sudhakar; Douglas, David; Mulligan, David


    Sclerosing peritonitis describes the development of a peel or rind of fibrosis that spreads over the peritoneal surface and can lead to recalcitrant ascites, bowel obstruction, and sepsis. It is well described as a complication of peritoneal dialysis, especially with episodes of bacterial peritonitis. It is also a complication of end-stage liver disease with ascites and liver transplantation. This article describes 3 cases of sclerosing peritonitis present at the time of liver transplantation or soon after. All 3 patients had massive refractory ascites with episodes of spontaneous bacterial peritonitis prior to transplantation. Two patients had evidence of a fibrous peel at the time of transplantation. Postoperatively, all 3 patients continued to have refractory ascites and episodes of peritonitis, along with partial small bowel obstructions, abdominal pain, and malnutrition. Two patients also had constriction of the graft, including biliary obstruction and inferior vena cava and outflow obstruction, which has not been previously described. All 3 patients eventually died from complications related to the sclerosing peritonitis.

  15. Employment after liver transplantation: a review. (United States)

    Huda, A; Newcomer, R; Harrington, C; Keeffe, E B; Esquivel, C O


    Return to productive employment is often an important milestone in the recovery and rehabilitation process after liver transplantation (OLT). This literature review identifies factors associated with employment in patients who underwent OLT. We searched PubMed for articles that addressed the various factors affecting employment after OLT. The studies demonstrated improvement in the quality of life and examined factors that predicted whether patients would return to work after OLT. Demographic variable associated with posttransplant employment included young age, male sex, college degree, Caucasian race, and pretransplant employment. Patients with alcohol-related liver disease had a significantly lower rate of employment than did those with other etiologies of liver disease. Recipients who were employed after transplantation had a significantly better posttransplant functional status than did those who were not employed. Economic pressures are increasing the expectation that patients who undergo successful OLT will return to work. Thus, transplant teams need to have a better understanding of posttransplant work outcomes for this vulnerable population, and greater attention must be paid to the full social rehabilitation of transplant recipients. Specific interventions for OLT recipients should be designed to evaluate and change their health perceptions and encourage their return to work. Published by Elsevier Inc.

    Seventeen female patients who underwent orthotopic liver transplantation between June 1973 and June 1987 became pregnant 5 months to 11 years after transplantation. Immunosuppression was maintained with combinations of prednisone, cyclosporine, and azathioprine prior to and during pregnancy. One patient discontinued immunosuppression after knowledge of pregnancy, taking only azathioprine sporadically. Mean age at time of delivery was 26 years. Twelve patients had no alteration in liver function studies; 7 patients demonstrated mild or moderate enzyme elevations prior to delivery, with one case of rejection confirmed by percutaneous liver biopsy. Major problems related to pregnancy were hypertension, anemia, and hyperbilirubinemia. Twenty live births occurred (2 patients had 2 separate pregnancies, one patient had a set of twins); 13 were by caesarian section, 7 by vaginal delivery. Eleven of the 13 caesarian births were premature by gestational age. All vaginal births were term. Toxemia of pregnancy and early rupture of membranes were the principal indications for caesarean section. There were no congenital abnormalities or birth defects and all the children are surviving well. Fifteen of 16 children older than one year all have normal physical and mental development, with one child manifesting immature speech development. Four children are under one year, all with normal milestones thus far. Sixteen of the 17 mothers are alive from 2–18 years after transplantation; the only death was from a lymphoma, almost 4 years after transplantation and 2½ years after delivery. This experience suggests that women undergoing liver transplantation can safely bear children despite an increased risk of premature caesarian births. The effect of chronic immunosuppression of female pediatric patients on their reproductive potential later in adulthood remains to be fully evaluated but the results so far are favorable.

  17. Seizures after liver transplantation: a clinicopathologic study. (United States)

    Estol, C J; Lopez, O; Brenner, R P; Martinez, A J


    We reviewed the clinical and neuropathologic findings in 21 patients who had seizures after orthotopic liver transplants. Tonic-clonic seizures were the most common seizure type. Six patients developed status epilepticus. In 9 patients, seizures occurred within 1 week following transplantation. We found CNS lesions that were probably responsible for the occurrence of seizures in most patients; some had more than 1 finding. Neuropathologic examination revealed ischemic or hemorrhagic strokes in 18 patients, central pontine myelinolysis in 5, and CNS infections in 5. Multiple metabolic abnormalities were a contributing factor to the onset of seizures in some patients.

There was decreased BMD in axial so as in peripheral skeleton in early time and in vertebral or hip Ward triangle in late time following transplantation being lower in primary biliary cirrosis then in cirrosis following chronic virus hepatitis despite tacrolimus immunosupression without prednisolon. Tacrolimus immunosupression with prednisolon in primary biliary cirrosis patients in late postoperative time was associated with hard BMD lowering which correlated with glucocorticoid therapy duration and prednisolon cumulative dosis.

    Liver transplantation (LT) is a viable treatment option for end-stage hepatic failure. Uludag University Liver Transplant Center has begun performing liver transplant operations in December 2007 and in this article, we review outcomes of 34 cases of LT performed until August 2010 including 30 cadaveric livers and 4 living donors. We achieved a 24-month survival rate of 84.2% in our center and LT surgeries continue with an acceptable success rate. 

  1. Split liver transplantation benefits the recipient of the 'leftover liver'. (United States)

    Dunn, S P; Haynes, J H; Nicolette, L A; Falkenstein, K; Pierson, A; Billmire, D F; Vinocur, C D; Weintraub, W


    The division of a single hepatic allograft to create two reduced-size grafts has been reported with decreased graft survival (50%) resulting in decreased enthusiasm for this approach. The authors reviewed their experience with 12 recipients of this procedure to evaluate the outcome of the children electively undergoing transplant with the "leftover liver." A retrospective review of six pairs of children receiving part of one hepatic allograft included donor anatomy, recipient operation, and allograft and patient outcomes. Recipient pairs were selected according to blood type compatibility, medical priority, and size restrictions of the larger right lobe and the smaller left lateral segment. Patient and graft survival were compared with elective and urgent patients undergoing whole or reduced-size transplants. Six donors weighed 71.8 +/- 17.4 kg and were 22.6 +/- 11.0 years of age. Recipients of the right lobe were 11.8 +/- 4.2 years of age and weighed 41.9 +/- 14 kg. Recipients of the left lateral segment were 1.81 +/- 1.1 years of age and weighed 9.85 +/- 1.82 kg. Six patients were initially offered the donor allograft because of their hospitalization, critical illness or waiting time. Six additional patients electively underwent transplantation with the leftover liver. Donor organs were screened for normal arterial anatomy. Division of the allograft was performed on the back table in the falciform groove. Generally the left lateral segment graft received the major portion of the hepatic artery and the right lobe the major portion of the portal vein. Five of six (83%) elective patients, two receiving the right lobe and three receiving the left lateral segment had prompt recovery and left the hospital without surgical complication. One recipient of a right lobe transplant died from primary allograft nonfunction. These results are not different from the outcomes of all elective patients who underwent transplantation with whole or reduced-sized transplants in the

    Koneru, Baburao; Jaffe, Ronald; Esquivel, Carlos O.; Kunz, Rainer; Todo, Satuoro; Iwatsuki, Shunzaburo; Starzl, Thomas E.


    Over a 5½-year period, 22 of 262 children receiving liver transplants developed adenoviral infections. Five had adenoviral hepatitis in the allograft, caused by serotype 5. All five were treated for rejection, either just before or at the time of infection. Liver biopsy specimens had characteristic histological appearance, and diagnosis of adenoviral infection was confirmed with monoclonal anti-adenoviral antibodies, electron microscopy, and by culture of liver tissue. In the remaining 17 patients, adenovirus was isolated from urine, stool, throat secretions, and/or blood samples, but none had any detectable visceral infection. Serotypes 1 and 2 predominated, similar to children not receiving transplants during the same time period. Three of the patients with hepatitis are alive and well; two died of liver failure. Adenoviral hepatitis did not recur in the second allograft of a patient who underwent retransplantation for combined rejection and adenoviral hepatitis, and appears, therefore, not to be a contraindication to retransplantation when liver failure ensues.

    Fifteen patients with Laennec's cirrhosis underwent orthotopic liver transplantation between 1963 and the end of 1979. The first eight patients died perioperatively or within two months, but four of the next seven patients had long survival; three are still alive after 11 to 14 years. After the introduction of cyclosporine therapy, 41 more patients with alcoholic cirrhosis were treated with liver transplantation from 1980 to June 1987. The one-year survival is 73.2%, and, after one to three years, 28 (68%) of the recipients are living. Of the 35 patients in the combined old and new series who lived for six months or longer, only two returned to alcohol abuse. Social and vocational rehabilitation has been the rule in these recipients who were selected primarily because of urgency of need, because they or their families insisted on treatment, and because they and their families thereby committed themselves to long-standing programs of alcoholism care.

    Little, J M


    Liver transplantation is one of the most spectacular of surgical achievements. It is a demanding and expensive procedure, requiring great surgical skill and a great depth of supporting services. Precisely because it is a procedure at the leading edge of medicine, more and more units in developed countries are pressing to be allowed to carry it out. But there are many moral and ethical problems, some of which can be usefully examined using a "Mozart model" as proposed by Starzl.

  8. Nonalcoholic fatty liver disease after liver transplantation for cryptogenic cirrhosis or nonalcoholic fatty liver disease. (United States)

    Yalamanchili, Kanthi; Saadeh, Sherif; Klintmalm, Göran B; Jennings, Linda W; Davis, Gary L


    Nonalcoholic steatohepatitis (NASH) may account for many cases of cryptogenic cirrhosis. If so, then steatosis might recur after liver transplantation. Two thousand fifty-two patients underwent primary liver transplantation for chronic liver disease between 1986 and 2004. Serial liver biopsy samples were assessed for steatosis and fibrosis. Two hundred fifty-seven patients (12%) had a pretransplant diagnosis of cryptogenic cirrhosis (239) or NASH (18). Fatty liver developed in 31% and was more common when the pretransplant diagnosis was NASH (45% at 5 years versus 23% for cryptogenic cirrhosis, P = 0.007). NASH developed in only 4% and occurred exclusively when steatosis had already occurred. Steatosis after liver transplantation was associated with the baseline body weight and body mass index by univariate analyses, but no pretransplant or posttransplant characteristic independently predicted steatosis after liver transplantation because obesity was so common in all groups. Five percent and 10% developed bridging fibrosis or cirrhosis after 5 and 10 years, respectively, and this was more common after NASH (31%) than in those who developed steatosis alone (6%) or had no fat (3%, P = 0.002). One-, 5-, and 10-year survival was the same in patients who underwent transplantation for cryptogenic cirrhosis or NASH (86%, 71%, and 56%) and in patients who underwent transplantation for other indications (86%, 71%, and 53%; not significant), but death was more often due to cardiovascular disease and less likely from recurrent liver disease. In conclusion, fatty liver is common after liver transplantation for cryptogenic cirrhosis or NASH but is twice as common in the latter group; this suggests that some cryptogenic cirrhosis, but perhaps not all, is caused by NASH. Posttransplant NASH is unusual, and steatosis appears to be a prerequisite. Advanced fibrosis is uncommon, and survival is the same as that of patients who undergo transplantation for other causes.

    Kanizaj, Tajana Filipec; Colić-Cvrlje, Vesna; Mrzljak, Anna; Ostojić, Rajko


    Hepatitis B infection (HBV) causes liver cirrhosis and hepatocellular carcinoma that are indications for orthotopic liver transplantation (OLT). The outcome of OLT depends on the prevention of HBV reinfection and disease relapses. Out of 692 liver transplantations performed at Merkur University Hospital, 30 were done for HBV infection. These patients were treated with HBIG post OLT and lamivudine, entecavir, adefovir, tenofovir prior and post OLT. All patients became HBsAg and HBV DNA negative but four of them became HbsAg positive one year post OLT. The patients survived for 2 months to 7 years post OLT. With the introduction of HBIG immunoprophylaxis and new efficient antiviral treatment, the risk of relapse is only < 10%, and survival is the same as in other indications for OLT. Because of the high cost and long-term treatment, efforts have been made to prevent recurrent HBV disease by using the schedules according to pre- and post-transplant HBV viremia and introducing the new potent antiviral analogue nucleos(t)ides.

  10. Liver transplantation as a management of hepatocellularcarcinoma

    Institute of Scientific and Technical Information of China (English)


    Hepatocellular carcinoma (HCC) is one of the mostcommon cancers worldwide and has a poor prognosisif untreated. It is ranked the third among the causesof cancer-related death. There are multiple etiologicfactors that can lead to HCC. Screening for early HCC ischallenging due to the lack of well specific biomarkers.However, early diagnosis through successful screeningis very important to provide cure rate. Liver transplantation(LT) did not gain wide acceptance until themid-1980s, after the effective immunosuppression withcyclosporine became available. Orthotopic LT is thebest therapeutic option for early, unresectable HCC.It is limited by both, graft shortage and the need forappropriate patient selection. It provides both, theremoval of tumor and the remaining cirrhotic liver. InMilan, a prospective cohort study defined restrictiveselection criteria known as Milan criteria (MC) that led tosuperior survival for transplant patients in comparisonwith any other previous experience with transplantationor other options for HCC. When transplantation occurswithin the established MC, the outcomes are similarto those for nonmalignant liver disease after transplantation.The shortage of organs from deceaseddonors has led to the problems of long waiting timesand dropouts. This has led to the adoption of extendedcriteria by many centers. Several measures have beentaken to solve these problems including prioritizationof patients with HCC, use of pretransplant adjuvanttreatment, and living donor LT.

    BACKGROUND Right lobe living donor liver transplantation (LDLT) remains the most common form of liver transplantation in Asia. However, reconstruction of the venous outflow in a right liver allograft may pose technical difficulties if hepatic venous variations are present. Recently, much emphasis has been given to the reconstruction of large and multiple inferior right hepatic veins (IRHVs). The method of reconstructive technique, type of vascular grafts, and the outcome after the procedure have been a point of debate. In this report we discuss the IRHV reconstruction techniques using expanded polytetrafluoroethylene (ePTFE) vascular grafts and the outcomes after such reconstruction. MATERIAL AND METHODS Out of 262 right liver allografts that underwent venous reconstruction using ePTFE vascular grafts, IRHVs required either venoplasty or second inferior vena cava (IVC) anastomosis in 99 recipients. Depending upon type of IRHV reconstruction, the recipients were divided in 2 groups: Group A (n=52): IRHV venoplasty using ePTFE graft, and group B (n=47): Direct IRHV-to-IVC anastomosis. The outcome after LDLT was compared for these 2 groups. RESULTS The ePTFE venoplasty group had significantly shorter warm ischemia time as compared to the direct to IVC anastomosis group (pgraft migration in the second portion of the duodenum that required surgical exploration. CONCLUSIONS The IRHVs drain a considerable portion of the posterior sector of right liver allografts and thus must be reconstructed. Use of ePTFE vascular grafts for IRHV venoplasty is a safe and feasible concept that facilitates the outflow reconstruction of liver allografts.

    A retrospective multicenter study has been conducted to evaluate domino liver transplantations (DLTs) in Germany. The study provides insight into survival and features having an impact on the assessment of neuropathy after DLT. In addition, a neurologic follow-up program with a scheme to estimate the likelihood of de novo amyloidosis is presented. A series of 61 DLTs at seven transplant centers in Germany was enrolled. The mean age of domino recipients at the time of transplantation was 58 years, 46 of them being men, and 15 being women. The median follow-up was 46 months. The overall 1-, 3-, and 5-year survival of domino recipients was 81.6%, 70.8% and 68.8%, respectively. Causes of death were primarily not related to familial amyloidosis. The main indication of DLT was hepatocellular carcinoma. Two of the reported domino recipients developed symptoms and signs of de novo amyloidosis within 10 years after transplantation. A total of 30 domino graft recipients (49.18%) presented with diabetes post transplantation. In conclusion, an advanced follow-up program is crucial to evaluate the risk of transmitting familial amyloidosis by DLT and to establish more strict selection criteria for domino recipients. © 2013 Steunstichting ESOT.

  16. De novo autoimmune hepatitis after liver transplantation. (United States)

    Lohse, Ansgar W; Weiler-Norman, Christina; Burdelski, Martin


    The Kings College group was the first to describe a clinical syndrome similar to autoimmune hepatitis in children and young adults transplanted for non-immune mediated liver diseases. They coined the term "de novo autoimmune hepatitis". Several other liver transplant centres confirmed this observation. Even though the condition is uncommon, patients with de novo AIH are now seen in most of the major transplant centres. The disease is usually characterized by features of acute hepatitis in otherwise stable transplant recipients. The most characteristic laboratory hallmark is a marked hypergammaglobulinaemia. Autoantibodies are common, mostly ANA. We described also a case of LKM1-positivity in a patients transplanted for Wilson's disease, however this patients did not develop clinical or histological features of AIH. Development of SLA/LP-autoantibodies is also not described. Therefore, serologically de novo AIH appears to correspond to type 1 AIH. Like classical AIH patients respond promptly to treatment with increased doses of prednisolone and azathioprine, while the calcineurin inhibitors cyclosporine or tacrolimus areof very limited value - which is not surprising, as almost all patients develop de novo AIH while receiving these drugs. Despite the good response to treatment, most patients remain a clinical challenge as complete stable remissions are uncommon and flares, relapses and chronic disease activity can often occur. Pathogenetically this syndrome is intriguing. It is not clear, if the immune response is directed against allo-antigens, neo-antigens in the liver, or self-antigens, possibly shared by donor and host cells. It is very likely that the inflammatory milieu due to alloreactive cells in the transplanted organ contribute to the disease process. Either leading to aberrant antigen presentation, or providing co-stimulatory signals leading to the breaking of self-tolerance. The development of this disease in the presence of treatment with calcineurin

  17. Salvage Liver Transplantation Leads to Poorer Outcome in Hepatocellular Carcinoma Compared with Primary Liver Transplantation (United States)

    Shan, Yuhua; Huang, Lifeng; Xia, Qiang


    Hepatocellular carcinoma is the most common liver malignancy. Salvage liver transplantation (SLT) is viewed as a feasible cure for recurrence of HCC after resectomy, but the effect is under dispute. A retrospective study examined data at Renji Hospital for 239 transplants from January 2006 to December 2015, including 211 who received primary liver transplantation (PLT) and 28 who underwent SLT. A multivariable cox regression model was employed to pick out relative factors to overall survival (OS) and recurrence free survival (RFS). Propensity score matching (PSM) was used to balance the bias. Both OS and RFS were worse in SLT group than in PLT group, especially for those patients within Milan criteria. Our study demonstrates that SLT bears higher risk of recurrence and death than PLT, indicating that SLT should be given a more careful thought at performance. PMID:28294176

    Various types of extracorporeal membrane oxygenation methods have been used in liver transplant operations. The main indications are portopulmonary or hepatopulmonary syndromes and other cardiorespiratory failure syndromes that are refractory to conventional therapy. There is little literature available about extracorporeal membrane oxygenation, especially after liver transplant. We describe our experience with 2 patients who had living-related liver transplant. A 69-year-old woman had refractory aspergillosis pneumonia and underwent pumpless extracorporeal lung assist therapy 4 weeks after liver transplant. An 8-month-old boy with biliary atresia underwent urgent liver transplant; he received venoarterial extracorporeal membrane oxygenation therapy on postoperative day 1. Despite our unsuccessful experience with 2 patients, extracorporeal membrane oxygenation and pumpless extracorporeal lung assist therapy for liver transplant patients may improve prognosis in selected cases.

  20. Liver transplantation for hepatocellular carcinoma: an update. (United States)

    Zarrinpar, Ali; Kaldas, Fady; Busuttil, Ronald W


    Hepatocellular carcinoma (HCC) is a heterogeneous malignancy with multiple etiologies, high incidence, and high mortality. The standard surgical management for patients with HCC consists of locoregional ablation, surgical resection, or liver transplantation, depending on the background state of the liver. Eighty percent of patients initially presenting with HCC are unresectable, either due to the extent of tumor or the level of underlying hepatic dysfunction. While in patients with no evidence of cirrhosis and good hepatic function resection has been the surgical treatment of choice, it is contraindicated in patients with moderate to severe cirrhosis. Liver transplantation is the optimal surgical treatment. PubMed search of recent articles (from January 2000 to March 2011) was performed looking for relevant articles about hepatocellular carcinoma and its treatment. Additional articles were identified by evaluating references from selected articles. Here we review criteria for transplantation, the types, indications, and role of locoregional therapy in treating the cancer and in downstaging for possible later transplantation. We also summarize the contribution of immunosuppression and adjuvant chemotherapy in the management and prevention of HCC recurrence. Finally we discuss recent advances in imaging, tumor biology, and genomics as we delineate the remaining challenges for the diagnosis and treatment of this disease. Much can be improved in the diagnosis and treatment of HCC. A great challenge will be to improve patient selection to criteria based on tumor biology. Another will be to incorporate systemic agents post-operatively in patients at high risk for recurrence, paying close attention to efficacy and safety. The future direction of the effort in treating HCC will be to stimulate prospective trials, develop molecular imaging of lymphovascular invasion, to improve recipient selection, and to investigate biomarkers of tumor biology.

  1. Role of basic studies in expanding the donor pool for liver transplantation

    BACKGROUND: Liver transplantation is an effective treatment for end-stage liver disease, but a huge gap remains between the number of people who need a liver transplant and the number of organs available. In order to maximize donor organ access for adult and pediatric recipients, novel surgical and liver replacement procedures have evolved. Newer surgical techniques include split cadaveric liver transplantation and living donor liver transplantation (LDLT). With marginal and abnormal donor livers, despite tremendous advances in surgical technology, individual surgical procedure can not be completely brought into play unless effective measurements and basal studies are undertaken. DATA SOURCES: A literature search of MEDLINE and the Web of Science database using "liver transplantation" and"expanding donor pool"was conducted and research articles were reviewed. RESULTS: Therapies directed toward scavenging O2-, inhibiting nicotinamide adenine dinucleotide phosphate oxidase, and/or immuno-neutralizing tumor necrosis factor-alpha may prove useful in limiting the liver injury induced by surgical procedures such as split liver transplantation or LDLT. Improved donor organ perfusion and preservation methods, modulation of inlfammatory cytokines, energy status enhancement, microcirculation amelioration, and antioxidant usage can improve non-heart beating donor liver transplantation. Effective measures have been taken to improve the local conditions of donor cells with steatosis, including usage of fat-derived hormone and inlfammatory mediators, ischemic preconditioning, depletion of Kupffer cells, and cytokine antibody and gene therapy. Double-ifltration plasmapheresis can effectively reduce HCV viremia and prevent HCV recurrence in patient with high HCV RNA levels after LDLT. CONCLUSIONS: Shortage of grafts and poor function of marginal and abnormal donor grafts put many patients at risk of death in waiting for liver transplantation. Advances in surgical

    Liver transplantation is the most extreme form of surgical management of patients with hepatic trauma, with very limited literature data supporting its use. The aim of this study was to assess the results of liver transplantation for hepatic trauma. This retrospective analysis based on European Liver Transplant Registry comprised data of 73 recipients of liver transplantation for hepatic trauma performed in 37 centers in the period between 1987 and 2013. Mortality and graft loss rates at 90 days were set as primary and secondary outcome measures, respectively. Mortality and graft loss rates at 90 days were 42.5% and 46.6%, respectively. Regarding general variables, cross-clamping without extracorporeal veno-venous bypass was the only independent risk factor for both mortality (P = 0.031) and graft loss (P = 0.034). Regarding more detailed factors, grade of liver trauma exceeding IV increased the risk of mortality (P = 0.005) and graft loss (P = 0.018). Moreover, a tendency above the level of significance was observed for the negative impact of injury severity score (ISS) on mortality (P = 0.071). The optimal cut-off for ISS was 33, with sensitivity of 60.0%, specificity of 80.0%, positive predictive value of 75.0%, and negative predictive value of 66.7%. Liver transplantation seems to be justified in selected patients with otherwise fatal severe liver injuries, particularly in whom cross-clamping without extracorporeal bypass can be omitted. The ISS cutoff less than 33 may be useful in the selection process.

    Full Text Available BACKGROUND: Liver transplantation can prolong survival in patients with end-stage liver disease. We have proposed that the Sequential Organ Failure Assessment (SOFA score calculated on post-transplant day 7 has a great discriminative power for predicting 1-year mortality after liver transplantation. The Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA score, a modified SOFA score, is a newly developed scoring system exclusively for patients with end-stage liver disease. This study was designed to compare the CLIF-SOFA score with other main scoring systems in outcome prediction for liver transplant patients. METHODS: We retrospectively reviewed medical records of 323 patients who had received liver transplants in a tertiary care university hospital from October 2002 to December 2010. Demographic parameters and clinical characteristic variables were recorded on the first day of admission before transplantation and on post-transplantation days 1, 3, 7, and 14. RESULTS: The overall 1-year survival rate was 78.3% (253/323. Liver diseases were mostly attributed to hepatitis B virus infection (34%. The CLIF-SOFA score had better discriminatory power than the Child-Pugh points, Model for End-Stage Liver Disease (MELD score, RIFLE (risk of renal dysfunction, injury to the kidney, failure of the kidney, loss of kidney function, and end-stage kidney disease criteria, and SOFA score. The AUROC curves were highest for CLIF-SOFA score on post-liver transplant day 7 for predicting 1-year mortality. The cumulative survival rates differed significantly for patients with a CLIF-SOFA score ≤8 and those with a CLIF-SOFA score >8 on post-liver transplant day 7. CONCLUSION: The CLIF-SOFA score can increase the prediction accuracy of prognosis after transplantation. Moreover, the CLIF-SOFA score on post-transplantation day 7 had the best discriminative power for predicting 1-year mortality after liver transplantation.

    Jiang, Shui-Ming; Zhang, Qi-Shun; Zhou, Guang-Wen; Huang, Shi-Feng; Lu, Hai-Ming; Peng, Cheng-Hong


    The aim of this study was to investigate the differences in portal hemodynamics between whole liver transplantation and living donor liver transplantation (LDLT). Twenty patients who underwent LDLT (the L group) and 42 patients who underwent whole liver transplantation (the W group) were enrolled, and colored Doppler ultrasonography was performed preoperatively and on postoperative days (PODs) 1, 3, 5, 7, 30, and 90. The changes in the portal blood flow velocity (PBV) and portal blood flow volume (PBF) were monitored. The graft and spleen sizes were measured with angiographic computed tomography, and upper endoscopy was used to measure esophageal varices on PODs 14, 30, and 90. Although the portal venous pressure (PVP) decreased after graft implantation, it was higher in the L group with a smaller graft size ratio (25.7 ± 5.1 cm H₂O for the L group and 18.5 ± 4.6 cm H₂O for the W group, P transplantation; however, the PBF and PBV peaks were significantly higher in the W group. The postoperative PVP and graft volume were greatly related to PBF on POD 1. Grafts in the L group regenerated rapidly after the operation, and the volume increased from 704 ± 115 to 1524 ± 281 mL as early as 1 month after transplantation. A rapid improvement in splenomegaly was observed in both groups. An improvement in esophageal varices was observed in the W group on POD 14 after transplantation, whereas no change was observed in the L group. The portal venous flow in patients with portal hypertension showed a high perfusion state after LDLT, but in contrast to whole liver transplantation, the PVP elevation after LDLT postponed the closing time of the collateral circulation and affected the recovery from splenomegaly.

    BACKGROUND:Hilar cholangiocarcinoma is a devastating disease. Surgery is the only potentially curative modality. However, the results of surgical resection for hilar cholangiocarcinomas are disappointing. The introduction of liver transplantation for this condition has brought new hope for the management of this disease. The aim of this review is to discuss the role of liver transplantation in this disease. DATA SOURCES:A MEDLINE search was conducted for the articles on liver transplantation for hilar cholangiocarcinoma. Their results have been compiled and compared with the existing literature on resection for this disease. RESULTS:The earlier series on liver transplantation for hilar cholangiocarcinoma were not encouraging because of poor patient selection. The Mayo Clinic protocol of neoadjuvant chemoradiation followed by liver transplantation has shown remarkable success (survival at 1-, 3-, and 5-year post-transplantation being 92%, 82%, and 82%, respectively). With better patient selection and integration of neoadjuvant chemoradiation, the long-term survival is superior to that of the patients who undergo resection, as shown by the published literature on resection. The limitations of organ availability can be overcome by the living donor liver transplantation programme. This review article discusses the rationale, pros and cons of liver transplantation vis-à-vis resection for hilar cholangiocarcinoma. CONCLUSIONS:Liver transplantation, especially living donor liver transplantation, is a new and exciting alternative to resection for hilar cholangiocarcinoma. Integration of neoadjuvant chemoradiation has the potential to further improve the curative potential of liver transplantation. The strategy of combining neoadjuvant chemoradiation and liver transplantation brings new hope for the treatment of this dififcult disease.

    Combined en bloc liver/pancreas transplantation (CLPT) was used primarily in the treatment of otherwise non-resectable upper abdominal malignancy. In fact, a more appropriate indication is in patients with liver disease and insulin-dependent diabetes mellitus (IDDM). Here, we report on two successful cases of CLPT at our hospital. One was a patient with non-resectable advanced liver cancer. The recipient survived for 23 mo and finally died of recurrent tumor. The other was a patient with severe biliary complication after orthotopic liver transplantation and preoperative IDDM. We performed CLPT with a modified surgical technique of preserving the native pancreas. He is currently liver-disease- and insulin-free more than 27 mo post-transplant. Based on our experience in two cases of abdominal cluster transplantation, we describe the technical details of CLPT and a modification of the surgical procedure. PMID:19469010

    BACKGROUND: The availability of donor organs limits the number of patients in need who are offered liver transplantation. Measures to expand the donor pool are crucial to prevent on-list mortality. The aim of this study was to evaluate the use of livers from deceased donors who were older than 75...... years. METHODS: Fifty-four patients who received a first liver transplant (D75 group) from 2001 to 2011 were included.

  11. Bypass during Liver Transplantation: Anachronism or Revival? Liver Transplantation Using a Combined Venovenous/Portal Venous Bypass—Experiences with 163 Liver Transplants in a Newly Established Liver Transplantation Program

    Directory of Open Access Journals (Sweden)

    Anne Mossdorf


    Full Text Available Introduction. The venovenous/portal venous (VVP bypass technique has generally become obsolete in liver transplantation (LT today. We evaluated our experience with 163 consecutive LTs that used a VVP bypass. Patients and Methods. The liver transplant program was started in our center in 2010. LTs were performed using an extracorporal bypass device. Results. Mean operative time was 269 minutes and warm ischemic time 43 minutes. The median number of transfusion of packed cells and plasma was 7 and 14. There was no intraoperative death, and the 30-day mortality was 3%. Severe bypass-induced complications did not occur. Discussion. The introduction of a new LT program requires maximum safety measures for all of the parties involved. Both surgical and anaesthesiological management (reperfusion can be controlled very reliably using a VVP bypass device. Particularly when using marginal grafts, this approach helps to minimise both surgical and anaesthesiological complications in terms of less volume overload, less use of vasopressive drugs, less myocardial injury, and better peripheral blood circulation. Conclusion. Based on our experiences while establishing a new liver transplantation program, we advocate the reappraisal of the extracorporeal VVP bypass.

  13. Intracardiac Thrombosis during Adult Liver Transplantation

    Directory of Open Access Journals (Sweden)

    Marina Moguilevitch


    Full Text Available Intracardiac thrombosis (ICT and pulmonary embolism (PE during adult liver transplantation are rare but potentially lethal complications. They are often overlooked because of significant diagnostic challenges. The combination of hemodynamic compromise and transesophageal echocardiography (TEE findings allows for correct diagnosis. A large variety of putative risk factors for ICT and PE have been suggested, but these events are considered to be multifactorial. There are different proposed treatment modalities for these devastating complications. Unfortunately, in spite of growing knowledge in this area, intraoperative and postoperative mortalities remain very high. The retrospective nature of the study of these events makes the case reports extremely valuable.

  14. Mozart's Requiem–Liver Transplantation in 1988 (United States)


    Liver transplantation is one of the most spectacular of surgical achievements. It is a demanding and expensive procedure, requiring great surgical skill and a great depth of supporting services. Precisely because it is a procedure at the leading edge of medicine, more and more units in developed countries are pressing to be allowed to carry it out. But there are many moral and ethical problems, some of which can be usefully examined using a “Mozart model” as proposed by Starzl. PMID:2282327


    Abbasov, P A


    In 2012 - 2013 years in 265 patients for liver transplantation was performed, including in 224 (84.5%)--from a living donor, in 41 (15.5%)--from the dead body. Using a Foley catheter to stop bleeding, and the imposition of vascular sutures during endovenectomy in portal vein thrombosis (PVT) and its possible damage under all conditions. In particular, PVT IV degree (Grade IV) in order to restore blood flow in the graft using the left gastric and renal vein is an alternative, if they are cryopreserved vein may be suitably used.

    Kirchner, K; Malessa, Ch; Herzberg, N; Krumnow, S; Habrecht, O; Scheuerlein, H; Bauschke, A; Settmacher, U


    A reproducible and transparent quality of clinical treatments plays an important role in the performance of a hospital. In liver transplantation (LT), this is particularly important for patient safety, resource planning, documentation, and quality management. Thus, the clinical pathway for LT was documented in an electronic format within our research project PIGE. Data from clinical information systems were linked to this pathway, which allows for process monitoring (the assessment of the current state for every patient in the LT process) and a retrospective analysis of all treatments in addition to all data pertaining to the treatment, for example, cost, time, number of personnel, etc.

  17. Donation after cardio-circulatory death liver transplantation

    Hieu Le Dinh; Arnaud de Roover; Abdour Kaba; Séverine Lauwick; Jean Joris; Jean Delwaide; Pierre Honoré


    The renewed interest in donation after cardio-circulatory death (DCD) started in the 1990s following the limited success of the transplant community to expand the donation after brain-death (DBD) organ supply and following the request of potential DCD families.Since then,DCD organ procurement and transplantation activities have rapidly expanded,particularly for nonvital organs,like kidneys.In liver transplantation (LT),DCD donors are a valuable organ source that helps to decrease the mortality rate on the waiting lists and to increase the availability of organs for transplantation despite a higher risk of early graft dysfunction,more frequent vascular and ischemia-type biliary lesions,higher rates of re-listing and re-transplantation and lower graft survival,which are obviously due to the inevitable warm ischemia occurring during the declaration of death and organ retrieval process.Experimental strategies intervening in both donors and recipients at different phases of the transplantation process have focused on the attenuation of ischemia-reperfusion injury and already gained encouraging results,and some of them have found their way from pre-clinical success into clinical reality.The future of DCD-LT is promising.Concerted efforts should concentrate on the identification of suitable donors (probably Maastricht category Ⅲ DCD donors),better donor and recipient matching (high risk donors to low risk recipients),use of advanced organ preservation techniques (oxygenated hypothermic machine perfusion,normothermic machine perfusion,venous systemic oxygen persufflation),and pharmacological modulation (probably a multi-factorial biologic modulation strategy) so that DCD liver allografts could be safely utilized and attain equivalent results as DBD-LT.

    Since 1981, 20 infants younger than 1 year of age received 26 orthotopic liver transplants. Immunosuppression was with cyclosporine and corticosteroids. Thirteen (65%) of the recipients were discharged from the hospital. To date, 12 (60%) of the 20 recipients are surviving, with follow-up of 1 to 56 months (average 14 months). The 5-year actuarial survival is 53.8%. The allograft liver function in the majority of surviving infants is excellent. The predominant causes of mortality were primary nonfunction of the allograft (three patients) and sepsis (three). Major morbidity was caused by hepatic artery thrombosis (five patients), gastrointestinal complications (six), biliary tract complications (five), and bacterial and viral infections (13). Six patients underwent retransplantation; three of these six survived. Results could be improved by prevention of hepatic artery thrombosis, by decreasing the incidence of sepsis, and by procurement of more and better suited pediatric donors. PMID:3550022

    Full Text Available Since April 2010 to December 2011 were performed 35 orthotopic transplantations of cadaveric whole liver. The indication for surgery was liver cirrhosis of different etiologies: 6 – autoimmune, 5 – primary biliary cirrhosis, 2 – toxic, 4 – unspecified, 18 – virus, two of which with the outcome in hepatocellular carcinoma. Caval anastomosis formed mainly «end-to-side». In five cases, to increase the arterial perfusion of the graft, we ligated the splenic artery. Surgical complications in the early postoperative period were seen in 4 patients (11.4%. In the late period we observed stricture of bile duct in 4 patients (11.4%. In their treatment we used various combinations of minimally invasive and open surgical procedures. 2 patients died (5.7% – one of them on the sixth day because of intrahepatic portal vein thrombosis, another one in 6 months with a recurrence of autoimmune cirrhosis and humoral graft rejection. 

  20. Recurrent disease following liver transplantation for nonalcoholic steatohepatitis cirrhosis. (United States)

    Malik, Shahid M; Devera, Michael E; Fontes, Paulo; Shaikh, Obaid; Sasatomi, Eizaburo; Ahmad, Jawad


    Recurrence of the original disease following liver transplantation is not uncommon and can lead to graft failure. There are limited data on recurrent fatty liver disease following liver transplantation. The aim of this study was to determine the incidence of recurrent fatty liver disease in patients with biopsy-proven nonalcoholic steatohepatitis, its effect on survival, and whether there are any predictive factors for recurrence. We analyzed patients undergoing liver transplantation for nonalcoholic steatohepatitis cirrhosis from 1997 to 2008 at a single center. Patients undergoing transplantation for cholestatic disease, alcohol, hepatitis C, or cryptogenic cirrhosis were controls. Ninety-eight patients underwent transplantation for nonalcoholic steatohepatitis cirrhosis. Recurrent fatty liver disease was seen in 70%, 25% had recurrent nonalcoholic steatohepatitis, and 18% had stage II/IV or greater fibrosis at a mean of 18 months. No patients with recurrent nonalcoholic steatohepatitis developed graft failure or required retransplantation at a follow-up of 3 years. No recipient or donor factors were associated with disease recurrence, although patients with recurrent nonalcoholic steatohepatitis had a higher incidence of diabetes, weight gain, and dyslipidemia at the time of diagnosis of recurrence. One-third of patients with recurrent nonalcoholic steatohepatitis had normal liver enzymes at the time of diagnosis post-transplantation. In conclusion, recurrent fatty liver disease is common following liver transplantation for nonalcoholic steatohepatitis cirrhosis but does not lead to early allograft failure. Recurrent nonalcoholic steatohepatitis can occur despite normal liver enzymes, and features of metabolic syndrome are associated with disease recurrence.

    From March 1980 to July 1987, 1000 patients with various end-stage liver diseases received orthotopic liver transplants. Of the 7000 patients, three hundred two had definite histories of bleeding from esophageal varices before transplantation. There were 287 patients with nonalcoholic liver diseases and 15 patients with alcoholic cirrhosis. All patients had very poor liver function, which was the main indication for liver transplantation. One- through 5-year actuarial survival rates of the 302 patients were 79%, 74%, 71%, 71%, and 71%, respectively. These survival rates are far better than those obtained with other available modes of treatment for bleeding varices when liver disease is advanced. Long-term sclerotherapy is the treatment of primary choice for bleeding varices. Patients in whom sclerotherapy fails should be considered for liver transplantation unless clear contraindications exist. PMID:3051474

    Temporary portocaval shunt and total hepatectomy is a technique used in the presence of toxic liver syndrome because of fulminant hepatic failure, hepatic trauma, primary non-function (PNF), and eclampsia. We performed this technique on four patients. An indication for anhepatic state was severe hemodynamic instability in three of them. Etiologies of these three patients were as follows: PNF after liver transplantation, ischemic hepatitis after right hepatic artery embolization, and massive reperfusion syndrome during a liver transplantation. In the fourth patient, during the liver transplantation when hepatic artery was ligated, a kidney carcinoma in the donor graft was discovered. We decided to complete the hepatectomy and to construct a temporary portocaval shunt. Mean anhepatic phases were 19 h and 15 min. All patients survived the two-stage liver transplantation procedure without major complications. Our cases demonstrated that temporary portocaval shunt while awaiting urgent liver transplantation could be an effective "bridge" in selected patients who develop toxic liver syndrome; however, a short time between portocaval shunt and transplantation and careful intensive care managements are mandatory.

    Liver transplantation has been remarkably effective in the treatment in patients with end-stage liver disease. However, disparity between solid-organ supply and increased demand is the greatest limitation, resulting in longer waiting times and increase in mortality of transplant recipients. This situation creates the need to seek alternatives to orthotopic liver transplantation.Hepatocyte transplantation or liver cell transplantation has been proposed as the best method to support patients. The procedure consists of transplanting individual cells to a recipient organ in sufficient quantity to survive and restore the function. The capacity of hepatic regeneration is the biological basis of hepatocyte transplantation. This therapeutic option is an experimental procedure in some patients with inborn errors of metabolism, fulminant hepatic failure and acute and chronic liver failure, as a bridge to orthotopic liver transplantation. In the Hospital La Fe of Valencia, we performed the first hepatocyte transplantation in Spain creating a new research work on transplant program. Copyright 2009 AEC. Published by Elsevier Espana.

    Liver transplantation is indicated in patients with acute liver failure,decompensated cirrhosis,hepatocellular carcinoma and rare liver-based genetic defects that trigger damage of other organs.Early referral to a transplant center is crucial in acute liver failure due to the high mortality with medical therapy and its unpredictable evolution.Referral to a transplant center should be considered when at least one complication of cirrhosis occurs during its natural history.However,because of the shortage of organ donors and the short-term mortality after liver transplantation on one hand and the possibility of managing the complications of cirrhosis with other treatments on the other,patients are carefully selected by the transplant center to ensure that transplantation is indicated and that there are no medical,surgical and psychological contraindications.Patients approved for transplantation are placed on the transplant waiting list and prioritized according to disease severity.Thus,the appropriate timing of transplantation depends on recipient disease severity and,although this is still a matter of debate,also on donor quality.These two variables are known to determine the "transplant benefit"(i.e.,when the expected patient survival is better with,than without,transplantation) and should guide donor allocation.

    Liver transplantation is the best treatment for end stage liver diseases. In April 2003, our institution started a Liver Transplantation Program for both pediatric and adults population. Shown the results of the Liver Transplantation Program in the UMAE 25 Monterrey N.L. This is a retrospective cohort study of patients with liver transplantation. A total of 51 liver transplantations have been done in 49 patients with two retrasplantation, 15 in children and 36 in adults. The principal indication for liver transplantation in children was biliary atresia and hepatitis C cirrhosis in adults. The acute renal failure was the main early complication, the acute cellular rejection in the mediate period, and the cardiovascular diseases as late complication related to obesity, metabolic syndrome, diabetes mellitus and hypertension. Overall survival at 1 and 5 years was 57.1 and 54.2%, respectively. During the first three years post-transplantation, the quality of life was good or very good. Although still a young and perfectible program, the effort of a multidisciplinary team has made possible to perform liver transplantation in two patient populations, pediatric and adults.

    Uribe, M; Hunter, B; Alba, A; Calabrán, L; Flores, L; Soto, P; Herzog, C


    The success rate of pediatric liver transplantation has improved in recent years. Advances in immunosuppression have reduced the risk of rejection, but have enhanced the risk of posttransplant lymphoproliferative disorder (PTLD). Since 1994, we have performed 197 orthotopic liver transplantations in 157 recipients younger than 15 years. Herein we have performed a retrospective study to review the incidence and clinical characteristics, along with the treatment and outcomes of PTLD diagnosed over this 14-year experience. We documented 8 cases of PTLD (5%), half of which occurred during the first 2 years posttransplantation; 5 presented with abdominal involvement and 2 with thoracic masses. The histological findings showed lymphoma in 6 cases. All were treated with reduction of immunosuppression and 2 received Rituximab. Three patients died, a mortality rate of 37.5%. One subject experienced rejection, and the others responded to treatment. PTLD is a life-threatening condition that requires a high index of suspicion, appropriate imaging, biopsy diagnosis, and prompt treatment to achieve positive results. Quantitative monitoring of Epstein-Barr virus load may be useful to detect a high-risk population.

    Malik, S M; deVera, M E; Fontes, P; Shaikh, O; Ahmad, J


    Nonalcoholic steatohepatitis (NASH) associated cirrhosis is an increasing indication for liver transplant (LT). The aim of this study was to determine outcome and poor predictive factors after LT for NASH cirrhosis. We analyzed patients undergoing LT from 1997 to 2008 at a single center. NASH was diagnosed on histopathology. LT recipients with hepatitis C, alcoholic or cholestatic liver disease and cryptogenic cirrhosis acted as matched controls. Ninety-eight LT recipients were identified with NASH cirrhosis. Compared to controls, NASH patients had a higher BMI (mean 32.3 kg/m2), and were more likely to be diabetic and hypertensive. Mortality after transplant was similar between NASH patients and controls but there was a tendency for higher earlier mortality in NASH patients (30-day mortality 6.1%, 1-year mortality 21.4%). Sepsis accounted for half of all deaths in NASH patients, significantly higher than controls. NASH patients > or =60 years, BMI > or =30 kg/m2 with diabetes and hypertension (HTN) had a 50% 1-year mortality. In conclusion, patients undergoing LT for NASH cirrhosis have a similar outcome to patients undergoing LT for other indications. The combination of older age, higher BMI, diabetes and HTN are associated with poor outcome after LT. Careful consideration is warranted before offering LT to these high-risk patients.

    New-onset diabetes after transplantation (NODAT) is a serious complication of liver transplantation (LT). The present study aimed to investigate the risk factors of NODAT by a national survey using the China Liver Transplant Registry database. A total of 10 204 non-pre-existing diabetic patients undergone primary LT between January 2000 and December 2013 were included. Risk factors were identified by logistic regression analysis. NODAT occurred in 24.3% of liver recipients with a median follow-up time of 2.6 years, and was associated with a significantly lower patient survival. NODAT increased not only diabetes related complications (e.g., infection, kidney failure) but also biliary stricture and cholangitis. NODAT patients who received hypoglycaemic treatment had a worse prognosis and a higher hepatocellular carcinoma recurrence compared with those without treatment. New-onset hyperglycaemia (9 h, recipient age >50 years, body mass index >25 kg/m(2) , other hepatitis (mainly hepatitis C), post-transplant intensive care unit stay >15 days, cytomegalovirus infection and corticosteroid at discharge. The incidence of NODAT in China is similar to that in Western countries. However, the NODAT-related complications are more common and severer in China compared with those in Western countries. The major risk factors are different. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Shimul A Shah


    Full Text Available The present review outlines the principles of living donor liver transplantation, donor workup, procedure and outcomes. Living donation offers a solution to the growing gap between the need for liver transplants and the limited availability of deceased donor organs. With a multidisciplinary team focused on donor safety and experienced surgeons capable of performing complex resection/reconstruction procedures, donor morbidity is low and recipient outcomes are comparable with results of deceased donor transplantation.

    Naik, Pradeep; Premsagar, B; Mallikarjuna, M


    The acute renal failure is the frequent medical complication observed in liver transplant patients. The objective of this study was to determine the cause of acute renal failure in post liver transplant patients. A total of 70 patients who underwent (cadaveric 52, live 18) liver transplantation were categorized based on clinical presentation into two groups, namely hepatorenal failure (HRF, n = 29), and Hepatic failure (HF, n = 41). All the patients after the liver transplant had received tacrolimus, mycophenolate and steroids. We analyzed the modification of diet in renal disease, (MDRD) serum urea, creatinine and albumin before and after 5th and 30th day of liver transplant and data was categorized into survivors and non-survivors group. In HRF survivor group, serum creatinine, and urea levels were high and, albumin, MDRD were low in pre- transplant and reached to normal levels on 30th day of post transplant, and 79.3 % of patients in this group showed resumption of normal kidney function. On the contrary in HRF nonsurvivor group, we did not observed any significant difference and 20.7 % of patients showed irreversible changes after the liver transplant. In HF survivor group, 82.9 % of liver failure patients did not show any deviation in serum creatinine, urea, albumin and MDRD, whereas in HF non survivor group, 17.1 % of liver failure patients who had HCV positive before the transplant developed acute renal failure. The levels of creatinine, urea, albumin and MDRD were normal before the transplant and on day 30th, the levels of albumin and MDRD were significantly low whereas serum urea, creatinine levels were high. In conclusion, based on these observations, an diagnosis and treatment of Acute renal failure is important among the liver transplantation cases in the early postoperative period.

  15. A review of the imaging and intervention of liver transplant complications.

    LENUS (Irish Health Repository)

    McEvoy, S


    Liver transplantation has become a successful surgical solution to a variety of medical and oncological parenchymal liver diseases. As a result, these patients are being encountered more frequently within diagnostic imaging departments which may be remote from the transplant centre. Radiologists must therefore be proficient in identifying normal post-transplant anatomy which involves the anastomosis of four structures between the donor and recipient, namely the hepatic artery, the main portal vein, the retro-hepatic inferior vena cava and the extra-hepatic bile ducts. A number of potential complications can arise involving any or all of these structures, which can be potentially devastating and lead to graft failure. Radiologists must familiarise themselves with the normal post-operative appearances of liver transplantation and become competent in diagnosing post-transplant complications. Where possible, complications should be treated using interventional radiological techniques, thus avoiding the need for repeat surgical intervention or retransplantation.

  16. Fluorescence spectroscopy for assessment of liver transplantation grafts concerning graft viability and patient survival (United States)

    Vollet Filho, José D.; da Silveira, Marina R.; Castro-e-Silva, Orlando; Bagnato, Vanderlei S.; Kurachi, Cristina


    Evaluating transplantation grafts at harvest is essential for its success. Laser-induced fluorescence spectroscopy (LIFS) can help monitoring changes in metabolic/structural conditions of tissue during transplantation. The aim of the present study is to correlate LIFSobtained spectra of human hepatic grafts during liver transplantation with post-operative patients' mortality rate and biochemical parameters, establishing a method to exclude nonviable grafts before implantation. Orthotopic liver transplantation, piggyback technique was performed in 15 patients. LIFS was performed under 408nm excitation. Collection was performed immediately after opening donor's abdominal cavity, after cold perfusion, end of back-table period, and 5 min and 1 h after warm perfusion at recipient. Fluorescence information was compared to lactate, creatinine, bilirubin and INR levels and to survival status. LIFS was sensitive to liver changes during transplantation stages. Study-in-progress; initial results indicate correlation between fluorescence and life/death status of patients.

  17. Liver transplantation in adults with portal vein thrombosis: Data from the China Liver Transplant Registry. (United States)

    Gao, Peng Ji; Gao, Jie; Li, Zhao; Hu, Zhi Ping; Leng, Xi Sheng; Zhu, Ji Ye


    Portal vein thrombosis (PVT) is a common complication in patients with liver cirrhosis. During liver transplantation (LT), PVT may complicate the procedure and lead to a poor prognosis. The aim of this study is to evaluate patients enrolled in the China Liver Transplant Registry, to understand the influence of PVT to the LT recipients. We collected data from patients who underwent LT and were entered into the China Liver Transplant Registry. All data of medical records and follow-up were retrospectively reviewed. The preoperative condition, duration of surgery, intraoperative blood loss, postoperative early and late PVT, and survival rates were compared between patients with PVT and those without PVT. Multivariate Cox analysis and survival analysis were used to determine the influence of PVT. A total of 20,524 cases were recruited into the study. In all, 1810 (8.82%) patients were diagnosed with preoperative PVT of various severities. All patients were followed up for an average of 30.25±33.25months (up to a maximum of 171.68months). Patients with PVT had a significantly longer operating time, more intraoperative blood loss and a higher rate of post-LT PVT (Ptransplantation centers. Copyright © 2016.

    Telesforo Bacchella

    Full Text Available CONTEXT AND OBJECTIVE: Expanded donor criteria (marginal grafts are an important solution for organ shortage. Nevertheless, they raise an ethical dilemma because they may increase the risk of transplant failure. This study compares the outcomes from marginal and non-marginal graft transplantation in 103 cases of liver transplantation due to chronic hepatic failure. DESIGN AND SETTING: One hundred and three consecutive liver transplantations to treat chronic liver disease performed in the Liver Transplantation Service of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo between January 2001 and March 2006 were retrospectively analyzed. METHODS: We estimated graft quality according to a validated scoring system. We assessed the pre-transplantation liver disease category using the Model for End-Stage Liver Disease (MELD, as low MELD ( 20. The parameters for marginal and non-marginal graft comparison were the one-week, one-month and one-year recipient survival rates, serum liver enzyme peak, post-transplantation hospital stay and incidence of surgical complications and retransplantation. The significance level was 0.05. RESULTS: There were no differences between the groups regarding post-transplantation hospital stay, serum liver enzyme levels and surgical complications. In contrast, marginal grafts decreased overall recipient survival one month after transplantation. Furthermore, low-MELD recipients of non-marginal grafts showed better one-week and one-month survival than did high-MELD recipients of marginal livers. After the first month, patient survival was comparable in all groups up to one year. CONCLUSION: The use of marginal graft increases early mortality in liver transplantation, particularly among high-MELD recipients.

  19. Multimodality Imaging of Cardiac Transthyretin Amyloidosis 16 Years After a Domino Liver Transplantation. (United States)

    Bechiri, M Y; Eliahou, L; Rouzet, F; Fouret, P-J; Antonini, T; Samuel, D; Adam, R; Adams, D; Slama, M S; Algalarrondo, V


    We report the case of a 62-year-old man hospitalized in May 2015 for symptomatic heart failure. His medical history included two liver transplantations. The first liver transplantation was performed in 1999 for a mixed alcoholic and hepatitis C-related cirrhosis and the patient received the liver of another patient with Val30Met transthyretin amyloidosis using the domino technique. In 2008, he complained of neuropathic pains and an iatrogenic-acquired transthyretin amyloidosis was diagnosed. On cardiac evaluation, amyloidosis was suspected. In March 2010, a second liver transplantation was performed with a deceased donor without complication. In May 2015, a first episode of symptomatic heart failure occurred and cardiac amyloidosis was investigated by a multimodality evaluation. Electrocardiogram, cardiac biomarkers, echocardiography, and cardiac MRI were in favor of the diagnosis of amyloidosis, whereas (99m) Tc-dicarboxypropane diphosphonate scintigraphy was not. Endomyocardial biopsy finally confirmed the positive diagnosis of iatrogenic-acquired cardiac amyloidosis. This case is, to the best of our knowledge, the first to report biopsy-proven cardiac amyloidosis induced by domino liver transplantation and progressing heart failure in spite of retransplantation. The diagnostic modalities are discussed. This case should alert physicians to the cardiac risk in domino liver transplanted patients. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Case series Patient: Male, 38 • Male, 48 Final Diagnosis: En-bloc transplantation (liver, kidney, pancreas) Symptoms: Encephalopathy • adynamia • ascites • asthenia Medication: — Clinical Procedure: En-bloc transplantation Specialty: Transplantology Objective: Unusual setting of medical care Background: En-bloc transplantation is a surgical procedure in which multiple organs are transplanted simultaneously. It has some similarities with multi-organ transplantation but offers certain advantages. This report highlights the experience of our interdisciplinary group regarding the treatment and follow-up of patients who received en-bloc transplantation, with the aim of encouraging the development of this surgical technique. Case Report: The first case is a 38-year-old patient with type 1 diabetes mellitus, liver cirrhosis, and chronic kidney failure who received an en-bloc transplant of the liver, pancreas, and kidney with no intraoperative complications. He had a prolonged hospital stay due to anemia and systemic inflammatory response syndrome, which were resolved successfully. At follow-up, he had no requirement for insulin or for dialysis, or for new interventions. The second case describes a 48-year-old patient with type 2 diabetes mellitus, renal failure, and liver cirrhosis who received an en-bloc transplant of the liver, pancreas, and kidney with no complications. During the postoperative period, the patient suffered a possible episode of acute tubular necrosis, which evolved towards improvement, with a tendency to normal metabolic and renal functioning, with no additional events. The patient is currently in follow-up and is insulin-independent. Conclusions: En-bloc transplantation is a safe procedure, which is technically simple and which achieves excellent results. This procedure is indicated in patients with end-stage renal disease, cirrhosis, and diabetes mellitus that is difficult to control. PMID:28148909

  1. NAFLD and liver transplantation: Current burden and expected challenges (United States)

    Pais, Raluca; Barritt, A. Sidney; Calmus, Yvon; Scatton, Olivier; Runge, Thomas; Lebray, Pascal; Poynard, Thierry; Ratziu, Vlad; Conti, Filomena


    Summary Because of global epidemics of obesity and type 2 diabetes, the prevalence of non-alcoholic fatty liver disease (NAFLD) is increasing both in Europe and the United States, becoming one of the most frequent causes of chronic liver disease and predictably, one of the leading causes of liver transplantation both for end-stage liver disease and hepatocellular carcinoma. For most transplant teams around the world this will raise many challenges in terms of preand post-transplant management. Here we review the multifaceted impact of NAFLD on liver transplantation and will discuss: (1) NAFLD as a frequent cause of cryptogenic cirrhosis, end-stage chronic liver disease, and hepatocellular carcinoma; (2) prevalence of NAFLD as an indication for liver transplantation both in Europe and the United States; (3) the impact of NAFLD on the donor pool; (4) the access of NAFLD patients to liver transplantation and their management on the waiting list in regard to metabolic, renal and vascular comorbidities; (5) the prevalence and consequences of post-transplant metabolic syndrome, recurrent and de novo NAFLD; (6) the alternative management and therapeutic options to improve the long-term outcomes with particular emphasis on the correction and control of metabolic comorbidities.

    At the turn of the new century, liver transplant procedures can finally be considered an efficient treatment option. Technology has helped transplant intervention become a preferred treatment for patients with progressive and irreversible liver failure. New immuno-suppressive drugs have been introduced which reduce the patient's immunological reaction to the implanted organ, entail minimal side effects and improve practical applications of liver transplantation. As a result of these technological advanced and proper disease management, liver transplant procedures are no longer thought of as an elite therapy, reserved for selected patients with end stage liver disease. In our opinion, it is now a sound and valid surgical option with strictly defined characteristics, indications and well-understood limits. Throughout the past decade, we have studied and applied this type of intervention and have come to terms with its rapid expansion at both the theoretical and practical levels. The most significant obstacle remaining today is the discrepancy between the ever increasing demand and limited supply of organs. The future of liver transplant lies in overcoming this obstacle. Liver transplant practice began at our Institute on 23 November 1990 with the first surgical intervention to replace an organ. In the past 10 years, we have exceeded 200 liver transplant procedures.

    We are not aware of a report detailing the complex obstetrical and medical management of twin pregnancy in the context of HIV infection and early post-liver transplantation period. Here we describe the successful outcome of a twin pregnancy in a 28-year-old HIV-positive female receiving antiretroviral therapy and immunosuppressive therapy who was the recipient of a liver transplant for previous drug-induced liver failure.

  4. Predictors of employment after liver transplantation. (United States)

    Sahota, Amandeep; Zaghla, Hassan; Adkins, Rodney; Ramji, Alnoor; Lewis, Susan; Moser, Jennifer; Sher, Linda S; Fong, Tse-Ling


    Employment after orthotopic liver transplantation (OLT) indicates recipients' physical/psychosocial adjustment. Our aim was to determine clinical, socioeconomic and health-related quality of life parameters influencing employment after OLT. Questionnaire on demographics, medical conditions, alcohol and drug use before/after OLT, and a validated 12-Item Short Form Health Survey (SF-12) were mailed to 126 adult OLT patients. Stepwise logistic regression was conducted to identify best predictors of post-OLT employment. Among non-retirees, 49% were employed after OLT. The predictors of employment were: employment status, income, disability status before OLT and Model of End Stage Liver Disease score. These variables had prediction rate of 82%. Individuals working during the five yr prior to OLT were likely to return to work (p6 months prior to OLT (p$80 000 before OLT compared with or=6 months prior to OLT, were less likely to work (p=0.0005). Severity/duration of liver dysfunction prior to OLT did not correlate with employment. Sense of physical health was poorer in those employed after OLT than in unemployed (p=0.0003). Socioeconomic factors were the most important predictors of post-OLT employment.

    BACKGROUND: At present, imaging is used not only to show the form of images, but also to make three-dimensional (3D) reconstructions and visual simulations based on original data to guide clinical surgery. This study aimed to assess the use of a medical image-processing system in liver transplantation surgery. METHODS: The data of abdominal 64-slice spiral CT scan were collected from 200 healthy volunteers and 37 liver cancer patients in terms of hepatic arterial phase, portal phase, and hepatic venous phase. A 3D model of abdominal blood vessels including the abdominal aorta system, portal vein system, and inferior vena cava system was reconstructed by an abdominal image processing system to identify vascular variations. Then, a 3D model of the liver was reconstructed in terms of hepatic segmentation and liver volume was calculated. The FreeForm modeling system with a PHANTOM force feedback device was used to simulate the real liver transplantation environment, in which the total process of liver transplantation was completed. RESULTS: The reconstructed model of the abdominal blood vessels and the liver was clearly demonstrated to be three-dimensionally consistent with the anatomy of the liver, in which the variations of abdominal blood vessels were identiifed and liver segmentation was performed digitally. In the model, liver transplantation was simulated subsequently, and different modus operandi were selected successfully. CONCLUSION: The digitized medical image processing system may be valuable for liver transplantation.

  6. Diminishing Use of Liver Biopsy among Liver Transplant Recipients for Hepatitis C. (United States)

    Aby, Elizabeth; Jimenez, Melissa A; Grotts, Jonathan F; Agopian, Vatche; French, Samuel W; Busuttil, Ronald W; Saab, Sammy


    Background and Aims: Hepatitis C virus (HCV) cirrhosis is the leading indication for liver transplantation in the United States and recurrent HCV following liver transplantation is a major cause of allograft loss and mortality. Liver biopsies are commonly used to identify recurrent HCV and determine the need for antiviral therapy. The introduction of direct-acting antiviral agents (DAAs) has changed the management of recurrent HCV infection. This study aimed to describe the role of liver biopsies in liver transplant recipients with HCV after the introduction of DAAs. Methods: A retrospective analysis was performed looking at the rate of liver biopsies post-liver transplantation for HCV. The analysis included 475 adult liver transplants for hepatitis C performed at the University of California, Los Angeles from January 1, 2006 to October 1, 2015. Patients were divided into two eras, pre- and post-introduction of DAAs on December 1, 2013. Results: In the era before the introduction of DAAs, the percentage of patients biopsied was significantly higher compared to the era after the introduction of DAAs (56.1% vs. 26.9%, p < 0.001). Conclusions: The introduction of DAAs has changed the management of liver biopsy following liver transplantation and the management of recurrent HCV. Given that DAAs are well tolerated and have high efficacy, liver biopsies are no longer routinely used to justify the use antiviral therapy following liver transplantation.

    Full Text Available Liver transplantation (LT is the only available live-saving procedure for children with irreversible liver failure. This paper reports our experience from the follow-up of 16 Greek children with end-stage liver failure who underwent a LT. Over a period of 15 years, 16 pediatric liver recipients received follow up after being subjected to OLT (orthotopic liver transplantation due to end-stage liver failure. Nine children initially presented with extrahepatic biliary atresia, 2 with acute liver failure after toxic mushroom ingestion, 2 with intrahepatic cholestasis, 2 with metabolic diseases and one with hepatoblastoma. Ten children received a liver transplant in the Organ Transplantation Unit of Aristotle University of Thessaloniki and the rest in other transplant centers. Three transplants came from a living-related donor and 13 from a deceased donor. Six children underwent immunosuppressive treatment with cyclo­sporine, mycophenolate mofetil and corticosteroids, and 7 with tacrolimus, mycophenolate mofetil and corticosteroids. Three out of 16 children died within the first month after the transplantation due to post-transplant complications. Three children presented with acute rejection and one with chronic organ rejection which was successfully managed. Five children presented with cytomegalovirus infection, 5 with Epstein-Barr virus, 2 with HSV1,2, 2 with ParvoB19 virus, 2 with varicella-zoster virus and one with C. Albicans infection. One child presented with upper gastrointestinal hemorrhage and one with small biliary paucity. A satisfying outcome was achieved in most cases, with good graft function, except for the patient with small biliary paucity who required re-transplantation. The long-term clinical course of liver transplanted children is good under the condition that they are attended in specialized centers.

    Liver transplants, originally obtained from deceased donors, can now be harvested from living donors as well. This technique, called living-donor liver transplantation (LDLT), provides an effective alternative means of liver transplantation and is a method of expanding the donor pool in light of the demand and supply imbalance for organ transplants. Imaging plays an important role in LDLT programmes by providing robust evaluation of potential donors to ensure that only anatomically suitable donors with no significant co-existing pathology are selected and that crucial information that allows detailed preoperative planning is available. Imaging evaluation helps to improve the outcome of LDLT for both donors and recipients, by improving the chances of graft survival and reducing the postoperative complication rate. In this review, we describe the history of LDLT and discuss in detail the application of imaging in donor assessment with emphasis on use of modern computed tomography (CT) and magnetic resonance imaging (MRI) techniques.

    Full Text Available Liver transplantation has become the effective therapeutic method for end-stage liver disease, but the incidence of biliary complications after liver transplantation remains high. With an increasing number of liver transplantation procedures from donation after cardiac death (DCD, it is necessary to investigate the risk factors for biliary complications after liver transplantation from DCD and enhance our understanding of such risk factors in order to reduce biliary complications after liver transplantation from DCD.

  10. Liver transplantation using grafts with rare metabolic disorders. (United States)

    Schielke, Astrid; Conti, Filomena; Goumard, Claire; Perdigao, Fabiano; Calmus, Yvon; Scatton, Olivier


    Metabolic diseases that involve the liver represent a heterogeneous group of disorders. Apart from the metabolic defect, the subject's liver functions may be normal. With the increasing need for organs, livers from donors with metabolic diseases other than familial amyloid polyneuropathy might be possibly used for transplantation. However, whether such livers qualify as grafts and how they might impact recipient outcome are still unanswered questions. This review of the literature summarizes current experience in the use of such grafts in the context of cadaveric, domino, and living-related liver transplantation.

    Non-alcoholic fatty liver disease(NAFLD) is a recognized problem in patients after orthotopic liver transplantation and may lead to recurrent graft injury. As the increased demand for liver allografts fail to match the available supply of donor organs, split liver transplantation(SLT) has emerged as an important technique to increase the supply of liver grafts. SLT allows two transplants to occur from one donor organ, and provides a unique model for observing the pathogenesis of NAFLD with respect to the role of recipient environmental and genetic factors. Here we report on two recipients of a SLT from the same deceased donor where only one developed non-alcoholic steatohepatitis(NASH), suggesting that host factors are critical for the development of NASH.

  12. Liver transplantation for hepatocellular carcinoma: recent advances in China. (United States)

    Lu, Tian Fei; Hua, Xiang Wei; Cui, Xiao Lan; Xia, Qiang


    Orthotopic liver transplantation is currently the best treatment option for selected patients with hepatocellular carcinoma (HCC). From 1980 to 2011, 8874 patients with HCC in China underwent liver transplantation. The organ donation classification criteria of China (China criteria), which are established by the Government of China, are divided into three parts: China criteria I, donation after brain death; China criteria II, donation after cardiac death and China criteria III, donation after dual brain-cardiac death. Data from the China Liver Transplant Registry(CLTR) System shows that patients within the Milan criteria have higher survival rates than those who are beyond these criteria. Based on CLTR data, altogether 416 patients received living-donor liver transplantation(LDLT) in China. Their 1-year and 3-year survival rates were significantly higher than those of the non-LDLT recipients. The most common early stage(transplantation) complications include pleural effusion, diabetes, peritoneal effusion or abscess, postoperative infection, hypertension and intraperitoneal hemorrhage; while the most common late stage (≥ 30 days after liver transplantation) complications were diabetes, hypertension, biliary complications,postoperative infection, tacrolimus toxicity and chronic graft rejection. The incidence of vascular complication, which is the main reason for acute graft failure and re-transplantation, was 2.4%. Liver transplantation is an effective treatment for patients with HCC in China.

    To overcome the shortage of appropriate-sized whole liver grafts for children, technical variant liver transplantation has been practiced for decades. We perform a meta-analysis to compare the survival rates and incidence of surgical complications between pediatric whole liver transplantation and technical variant liver transplantation. To identify relevant studies up to January 2014, we searched PubMed/Medline, Embase, and Cochrane library databases. The primary outcomes measured were patient and graft survival rates, and the secondary outcomes were the incidence of surgical complications. The outcomes were pooled using a fixed-effects model or random-effects model. The one-year, three-year, five-year patient survival rates and one-year, three-year graft survival rates were significantly higher in whole liver transplantation than technical variant liver transplantation (OR = 1.62, 1.90, 1.65, 1.78, and 1.62, respectively, ptechnical variant liver transplantation. Continuing efforts should be made to minimize surgical complications to improve the outcomes of technical variant liver transplantation.

    Kasahara, Mureo; Sakamoto, Seisuke; Shigeta, Takanobu; Uchida, Hajime; Hamano, Ikumi; Kanazawa, Hiroyuki; Kobayashi, Megumi; Kitajima, Toshihiro; Fukuda, Akinari; Rela, Mohamed


    Liver transplantation is now an established treatment for children with end-stage liver disease. Left lateral segment (LLS) grafts are most commonly used in split and living donor liver transplantation in children. In very small children, LLS grafts can be too large, and further nonanatomical reduction has recently been introduced to mitigate the problem of large-for-size grafts. However, the implantation of LLS grafts can be a problem in infants and very small children because of the thickness of the grafts, and these techniques do not address problems related to thickness. We herein describe a technique for reducing the thickness of living donor left lateral grafts and successful transplantation in a 2.8-kg infant with acute liver failure.

    The aim of this work was to determine the impact of obesity on the morbidity and mortality of liver transplantation (LT) recipients. A single-center, observational-cohort, retrospective study was conducted in patients undergoing LT from January 2008 to December 2014 to compare complications and survival between those with body mass index (BMI) <35 kg/m(2) and those with BMI ≥35 kg/m(2). The study included 170 patients: 162 (95.3%) with BMI <35 kg/m(2) and 8 (4.7%) with BMI ≥35 kg/m(2). The groups significantly differed in overall mortality and graft survival: The risk of death was 3.54-fold higher (95% confidence interval, 1.39-9.03) and the mean graft survival was shorter (61 vs 21 mo; P = .001) in the group with BMI ≥35 kg/m(2). The groups did not significantly differ in rates of biliary complications, arterial and portal vein thrombosis, retransplantation or reintervention, intraoperative requirement for blood products, length of intensive care unit stay, or post-reperfusion syndrome or rejection rates. Although no significant differences were found between these groups in post-transplantation complications, BMI ≥35 kg/m(2) emerged as a mortality risk factor in these patients. Copyright © 2016.

  17. Liver transplantation for hepatocellular carcinoma on cirrhosis: Strategies to avoid tumor recurrence

    Institute of Scientific and Technical Information of China (English)

    Marco Vivarelli; Andrea Risaliti


    Hepatocellular carcinoma (HCC) is one of the most frequent neoplasms worldwide and in most cases it is associated with chronic liver disease. Liver trans-plantation (LT) is potentially the optimal treatment for those patients with HCC who have a poor functional hepatic reserve due to their underlying chronic liver disease. However, due to the limited availability of donors, only those patients whose oncologic profile is favorable can be considered for LT. Despite the care-ful selection of candidates based on strict rules, 10 to 20% of liver transplant recipients who have HCC in the native cirrhotic liver develop tumor recurrence after transplantation. The selection criteria pres-ently employed to minimize the risk of recurrence are based on gross tumor characteristics defined by imaging techniques; unfortunately, the accuracy of imaging is far from being optimal. Furthermore, mi-croscopic tumor features that are strictly linked with prognosis can not be assessed prior to transplanta-tion. Pre-transplantation tumor downstaging may allow transplantation in patients initially outside the selection criteria and seems to improve the progno-sis; it also provides information on tumor biology. The main peculiarity of the transplantation setting, when this is compared with other modalities of treatment, is the need for pharmacological immunosuppression: this is based on drugs that have been demonstrated to increase the risk of tumor development. As HCC is an aggressive malignancy, immunosuppression has to be handled carefully in patients who have HCC at the time of transplantation and new categories of immu-nosuppressive agents should be considered. Adjuvant chemotherapy following transplantation has failed to show any significant advantage. The aim of the pres-ent study is to review the possible strategies to avoid recurrence of HCC after liver transplantation based on the current clinical evidence and the more recent de-velopments and to discuss possible future directions.

  19. Brain death and marginal grafts in liver transplantation. (United States)

    Jiménez-Castro, M B; Gracia-Sancho, J; Peralta, C


    It is well known that most organs for transplantation are currently procured from brain-dead donors; however, the presence of brain death is an important risk factor in liver transplantation. In addition, one of the mechanisms to avoid the shortage of liver grafts for transplant is the use of marginal livers, which may show higher risk of primary non-function or initial poor function. To our knowledge, very few reviews have focused in the field of liver transplantation using brain-dead donors; moreover, reviews that focused on both brain death and marginal grafts in liver transplantation, both being key risk factors in clinical practice, have not been published elsewhere. The present review aims to describe the recent findings and the state-of-the-art knowledge regarding the pathophysiological changes occurring during brain death, their effects on marginal liver grafts and summarize the more controversial topics of this pathology. We also review the therapeutic strategies designed to date to reduce the detrimental effects of brain death in both marginal and optimal livers, attempting to explain why such strategies have not solved the clinical problem of liver transplantation.

  20. Transplant center quality assessment using a continuously updatable, risk-adjusted technique (CUSUM). (United States)

    Axelrod, D A; Guidinger, M K; Metzger, R A; Wiesner, R H; Webb, R L; Merion, R M


    Access to timely, risk-adjusted measures of transplant center outcomes is crucial for program quality improvement. The cumulative summation technique (CUSUM) has been proposed as a sensitive tool to detect persistent, clinically relevant changes in transplant center performance over time. Scientific Registry of Transplant Recipients data for adult kidney and liver transplants (1/97 to 12/01) were examined using logistic regression models to predict risk of graft failure (kidney) and death (liver) at 1 year. Risk-adjusted CUSUM charts were constructed for each center and compared with results from the semi-annual method of the Organ Procurement and Transplantation Network (OPTN). Transplant centers (N = 258) performed 59 650 kidney transplants, with a 9.2% 1-year graft failure rate. The CUSUM method identified centers with a period of significantly improving (N = 92) or declining (N = 52) performance. Transplant centers (N = 114) performed 18 277 liver transplants, with a 13.9% 1-year mortality rate. The CUSUM method demonstrated improving performance at 48 centers and declining performance at 24 centers. The CUSUM technique also identified the majority of centers flagged by the current OPTN method (20/22 kidney and 8/11 liver). CUSUM monitoring may be a useful technique for quality improvement, allowing center directors to identify clinically important, risk-adjusted changes in transplant center outcome.

  1. [Vascular Problem Constellations and the Operational Tactical Approaches in Post-Mortem Liver Transplantations]. (United States)

    Bauschke, A; Malessa, C; Rauchfuß, F; Gajda, M; Settmacher, U


    In liver transplantation, vascular problems may occur in the donor as well as in the recipient and during the donor operation as well as during the transplantation. They have a major influence on the outcome of the transplantation. In addition to anatomic variants, arteriosclerotic vascular diseases, complications from portal hypertension, vascular lesions from mistakes during the donor operation, complications from interventions and bridging procedures need to be identified and treated. In addition to duplex sonography and contrast enhanced computed tomography, invasive vascular diagnostics (digital subtraction angiography) are established for diagnostic purposes. Problem constellations should be identified prior to transplantation and the technique of the donor operation and the transplantation should be adjusted accordingly. Problems that are diagnosed after transplantation may be treated interventionally or with open surgery. In a number of cases, vascular complications lead to loss of the transplant or death of the recipient from post-operative organ failure.

  2. Preconditioning of the liver for efficient repopulation by primary hepatocyte transplants. (United States)

    Krause, Petra; Rave-Frank, Margret; Christiansen, Hans; Koenig, Sarah


    The therapeutic potential of liver cell transplantation has been demonstrated in multiple clinical studies to correct hereditary metabolic or chronic liver diseases. However, there are several outstanding issues, which need to be investigated: most notably donor cell engraftment and the subsequent selective expansion of transplanted cells. This protocol describes the preconditioning of the liver in a dipeptidyl peptidase-IV (DPPIV(-))-deficient rat model of efficient repopulation utilizing a selective external beam irradiation technique combined with regional transient portal ischemia (RTPI). Irradiation of the host liver impairs endogenous cell division, and the subsequent RTPI constitutes a strongly proliferative stimulus. Transplanted cells benefit from this stimulus, whereas endogenous cells have no ability to respond, due to a reduction in the mitotic capacity of the host liver. As described here, an effective preparative regime for liver repopulation is external beam liver irradiation in the form of a single dose of 25 Gy applied to the whole organ followed (4 days later) by RTPI of the right liver lobes lasting 90 min. After 1 h of reperfusion, the donor hepatocytes may be transplanted directly into the spleen as implantation site for further redistribution into the portal system and liver. This preparative regime certainly has the potential to be implemented in the clinic, since neither toxins nor highly potent carcinogens are used.

    Full Text Available Since 2008 up to 2010 eight ABO-incompatible liver transplantations have been performed in our center: one of them was urgent liver transplantation to adult patient from deceased donor, other seven were transplantations of left lateral segment to children from living relative donors. Own experience, as well as world one, proves, that barrier of ABO-incompatibility can be overcome more successfully in liver transplantation, particularly in pediatric population, that in other solid organs transplantation. Good results can be achieved even with less ag- gressive immunosuppressive therapy. Recipient conditioning before operation can significantly improve results of ABO-incompatible liver transplantation, but as own experience has shown, often there’s no need to hold some special preparation of children, because their anti-ABO antibodies are very low or absent before transplantation and do not increase after it. Thereby ABO-incompatible liver transplantation is reasonable in urgent cases and in pediatric population because of the limited pull of living relative donors for children.

    Full Text Available Objective: to compare the quality of life of liver transplant patients who received liver from donor aged ≤60 or >60 years old. Methods: a prospective study with a sample of 141 recipients from liver donors aged equal to or less than 60 years and recipients of elderly donor liver, in a reference center. Authors used a tool for identification and the Short Form-36. The Student-t and Mann-Whitney tests were applied for comparison between groups. Results: there were higher levels of quality of life with a statistically significant difference: Group A in social aspect (p=0.02 and Group B >50 months of transplantation (p=0.05 in physical component summary. Conclusion: the quality of life of liver receptors from older donor livers was similar to those who received a graft from younger donors in most dimensions. Transplanting time had a positive impact on the quality of life of elderly recipients.

  5. Treatment of addictive behaviors in liver transplant patients. (United States)

    Weinrieb, Robert M; Lucey, Michael R


    Very little addiction treatment research has been done concerning smoking cessation, illicit drugs, or even alcohol abuse in liver transplant patients. Our data suggest that a surprising number of patients who are awaiting a liver transplant for alcohol-related end-stage liver disease will return to drinking before transplantation. We found that motivational enhancement therapy afforded no marked benefit over treatment as usual for drinking, smoking, mood, or general health outcomes in alcoholics awaiting liver transplantation. Stably abstinent methadone-maintained opiate-dependent patients should not be tapered off methadone; are generally good candidates for liver transplant; show low relapse rates into illicit use of opiates; and may be at risk for more medical complications than their counterparts. Pre- and posttransplantation smoking rates are high and cause marked morbidity and mortality. Transplant teams should encourage smoking cessation treatments.Marijuana use in liver transplant recipients is not uncommon, and apart from the risk of developing aspergillosis, additional health risks have not yet been identified.

  6. Underutilization of palliative care services in the liver transplant population (United States)

    Kathpalia, Priya; Smith, Alexander; Lai, Jennifer C


    AIM To evaluate use of palliative care services in patients with end-stage liver disease who do not have access to liver transplant. METHODS Evaluated were end-stage liver disease patients who were removed from the liver transplant wait-list or died prior to transplant at a single transplant center over a 2-year period. Those who were removed due to noncompliance or ultimately transplanted elsewhere were excluded from this study. Patient characteristics associated with palliative care consultation were assessed using logistic regression analysis. RESULTS Six hundred and eighty-three patients were listed for liver transplant in 2013-2014 with 107 (16%) dying (n = 62) or removed for clinical decompensation prior to liver transplant (n = 45): Median age was 58 years, and the majority were male (66%), Caucasian (53%), had Child C cirrhosis (61%) or hepatocellular carcinoma (52%). The palliative care team was consulted in only 18 of the 107 patients (17%) who died or were removed, 89% of which occurred as inpatients. Half of these consultations occurred within 72 h of death. In univariable analysis, patients of younger age, white race, and higher end-stage liver disease scores at time of listing and delisting were more likely to receive palliative care services. Only younger age [Odds ratio (OR) = 0.92; P = 0.02] and Caucasian race (OR = 4.90; P = 0.02) were still associated with integration of palliative care services through multivariable analysis. CONCLUSION Palliative care services are grossly underutilized in older, non-white patients with cirrhosis on the liver transplant wait-list. We encourage early integration of these services into clinical decision-making in the transplant population, with further studies aimed at understanding barriers to consultation. PMID:27683638

    Full Text Available Objective: To evaluate the influence of end-stage liver disease and orthotopic liver transplantation in the pituitary function and hormone metabolism before and after liver transplantation. Methods: In a prospective study, serum levels of follicle stimulating hormone (FSH, luteinizing hormone (LH, estradiol (E2 and prolactin (PRL of 30 male patients with cirrhosis were determined two to four hours before and six months after liver transplantation. The results were compared according to the Model for End-stage Liver Disease (MELD. Results: male patients with liver cirrhosis have hypogonadism. FSH was normal, but inappropriately low due to androgen failure; E2 and PRL, on their turn, were high. After liver transplantation, FSH and LH levels increased (p 18. The severity of cirrhosis had no influence on FSH, PRL and LH.

    AIM: The aim of this study was to describe an auxiliary combined liver-small bowel transplantation model with the preservation of duodenum, head of pancreas and hepatic biliary system in pigs. The technique, feasibility, security and immunosuppression were commented.METHODS: Forty outbred long-white pigs were randomized into two groups, and the auxiliary composite liver/small bowel allotransplantations were undertaken in 10 long-white pigs in each group with the recipient liver preserved.Group A was not treated with immunosuppressive drugs while group B was treated with cyclosporine A and methylprednisolone after operation. The hemodynamic changes and amylase of body fluid (including blood, urine and abdominal drain) were analyzed.RESULTS: The average survival time of the animals was 10±1.929 d (6 to 25 d) in group A while more than 30 d in group B. The pigs could tolerate the hemodynamic fluctuation during operation and the hemodynamic parameters recovered to normal 2 h after blood reperfusion. The transient high amylase level was decreased to normal one week after operation and autopsy showed no pancreatitis.CONCLUSION: Auxiliary en-bloc liver-small bowel transplantation with partial pancreas preservation is a feasible and safe model with simplified surgical techniques for composite liver/small bowel transplantation. This model may be used as a preclinical training model for clinical transplantation method, clinical liver-small bowel transplantation related complication research, basic research including immunosuppressive treatment, organ preservation, acute rejection, chronic rejection, immuno-tolerance and xenotransplantation.

  9. New Insights in Recurrent HCV Infection after Liver Transplantation

    Directory of Open Access Journals (Sweden)

    Shih-Hsien Hsu


    Full Text Available Hepatitis C virus (HCV is a small-enveloped RNA virus belonging to the Flaviviridae family. Since first identified in 1989, HCV has been estimated to infect 170 million people worldwide. Mostly chronic hepatitis C virus has a uniform natural history, from liver cirrhosis to the development of hepatocellular carcinoma. The current therapy for HCV infection consists of a combination of Pegylated interferon and ribavirin. On the other hand, HCV-related liver disease is also the leading indication for liver transplantation. However, posttransplant HCV re-infection of the graft has been reported to be universal. Furthermore, the graft after HCV re-infection often results in accelerated progression to liver failure. In addition, treatment of recurrent HCV infection after liver transplantation is often compromised by enhanced adverse effects and limited efficacy of interferon-based therapies. Taken together, poor outcome after HCV re-infection, regardless of grafts or recipients, poses a major issue for the hepatologists and transplant surgeons. The aim of this paper is to review several specific aspects regarding HCV re-infection after transplant: risk factors, current therapeutics for HCV in different stages of liver transplantation, cellular function of HCV proteins, and molecular mechanisms of HCV entry. Hopefully, this paper will inspire new strategies and novel inhibitors against recurrent HCV infection after liver transplantation and greatly improve its overall outcome.

  10. Liver transplantation in the mouse: Insights into liver immunobiology, tissue injury, and allograft tolerance. (United States)

    Yokota, Shinichiro; Yoshida, Osamu; Ono, Yoshihiro; Geller, David A; Thomson, Angus W


    The surgically demanding mouse orthotopic liver transplant model was first described in 1991. It has proved to be a powerful research tool for the investigation of liver biology, tissue injury, the regulation of alloimmunity and tolerance induction, and the pathogenesis of specific liver diseases. Liver transplantation in mice has unique advantages over transplantation of the liver in larger species, such as the rat or pig, because the mouse genome is well characterized and there is much greater availability of both genetically modified animals and research reagents. Liver transplant experiments using various transgenic or gene knockout mice have provided valuable mechanistic insights into the immunobiology and pathobiology of the liver and the regulation of graft rejection and tolerance over the past 25 years. The molecular pathways identified in the regulation of tissue injury and promotion of liver transplant tolerance provide new potential targets for therapeutic intervention to control adverse inflammatory responses/immune-mediated events in the hepatic environment and systemically. In conclusion, orthotopic liver transplantation in the mouse is a valuable model for gaining improved insights into liver biology, immunopathology, and allograft tolerance that may result in therapeutic innovation in the liver and in the treatment of other diseases.

    Jin-Fang Zheng; Li-Jian Liang; Chang-Xiong Wu; Jin-Song Chen; Zhen-Sheng Zhang


    AIM: To investigate the effect of transplanted fetal liver epithelial progenitor (FLEP) cells on liver fibrosis in mice.METHODS: FLEP cells were isolated from embryonal day (ED) 14 BALB/c mice and transplanted into female syngenic BALB/c mice (n = 60). After partial hepatectomy (PH), diethylnitrosamine (DEN) was administered to induce liver fibrosis. Controls received FLEP cells and non-supplemented drinking water, the model group received DEN-spiked water, and the experimental group received FLEP cells and DEN.Mice were killed after 1, 2, and 3 mo, and alanine aminotransferase (ALT), aspartate aminotransferase (AST), hyaluronic acid (HA), and laminin (LN) in serum,and hydroxyproline (Hyp) content in liver were assessed.Alpha-smooth muscle actin (α-SMA) of liver was tested by immunohistochemistry. Transplanted male mice FLEP cells were identified by immunocytochemistry for sry (sex determination region for Y chromosome) protein.RESULTS: Serum ALT, AST, HA, and LN were markedly reduced by transplanted FLEP cells. Liver Hyp content and α-SMA staining in mice receiving FLEP cells were lower than that of the model group, which was consistent with altered liver pathology. Transplanted cells proliferated and differentiated into hepatocytes and bile duct epithelial cells with 30%-50% repopulation in the liver fibrosis induced by DEN after 3 mo.CONCLUSION: Transplanted FLEP cells proliferate and differentiate into hepatocytes and bile duct epithelial cells with high repopulation capacity in the fiberized liver induced by DEN, which restores liver function and reduces liver fibrosis.

    BACKGROUND: Graft loss after liver transplantation remains a significant problem, especially in pediatric patients. The aim of this study was to assess our initial series of pediatric liver transplantation and to identify the risk factors that influence graft outcome. METHODS: The first 51...... status of the recipients (hospitalization or intensive care unit care before surgery), a retransplanted graft, and a reduced-size graft were independent risk factors for graft failure. With experience, overall graft survival has improved significantly and the differences in graft survival between graft...... types have disappeared. CONCLUSIONS: To improve graft survival after pediatric liver transplantation, the timely referral of potential recipients to the transplant team and employing a meticulous technique during the operation, particularly for the technical-variant graft, are required....

  13. Effects of different mitogens on intrasplenic liver tissue transplants in comparison to orthotopic liver. (United States)

    Lupp, Amelie; Lucas, Norma; Tralls, Manuela; Fuchs, Udo; Danz, Manfred


    Ectopic liver cell transplants, when compared to orthotopic liver, can serve as a tool to study topic influences on liver cell differentiation, multiplication, function and responsiveness to xenobiotics. The aim of the present study was to evaluate, if characteristic effects of mitogens are exerted in both liver and intrasplenic liver cell transplants in a similar manner. Fetal liver tissue suspensions were transplanted into the spleens of adult male syngenic rats. Four months later, transplant recipients and controls were treated with fluorene (FEN), fluorenone (FON), 2-acetylaminofluorene (AAF), N-nitrosodibenzylamine (NDBA) or the solvent 48 hours before sacrifice. The following parameters were assessed within livers and spleens: mitotic activity of hepatocytes, glycogen content, cytochrome P450 (P450) isoforms expression, P450 mediated monooxygenase functions, tissue content of lipid peroxides (LPO) and of reduced and oxidized glutathione (GSH; GSSG). In both orthotopic livers and intrasplenic transplants FEN, FON or NDBA administration increased the mitotic activity of the hepatocytes. Treatment with the mitogens caused a distinct and characteristic induction of the P450 isoforms expression and of the respective monooxygenase functions in the livers and (with certain differences) also in the transplants. FEN and FON slightly increased, AAF and NDBA reduced liver glycogen content. The latter effect was also seen in the transplants. NDBA administration caused a slight increase in tissue LPO content in livers, but not in spleens. Additionally, AAF or NDBA treatment led to an elevation of liver (but not of spleen) GSH and GSSG concentrations. The results of the present investigation show that characteristic effects of mitogens on orthotopic liver occur with certain differences also in ectopic liver cell transplants.

  14. Diet and nutrition therapy in pre-liver transplant patients

    Neha Bakshi; Kalyani Singh


    Malnutrition is universaly prevalent among pre-liver transplantation patients. Malnutrition among cirrhotic patients had been associated to increased morbidity and mortality rates. Also, severely malnourished patients before the transplant surgery have a higher rate of complications and a decreased overal survival rate after liver transplantation. In light of the high incidence of malnutrition and associated complications, it is essential to initiate treatment as early as it is assessed. This review addresses the aetiologies of malnutrition and appropriate treatment strategies to correct it in pre-liver transplant phase. Treatment should focus on maintaining nutrient intake and correcting various nutritional deifciencies. The dietician plays an integral role as part of the transplant team by providing appropriate nutrition therapy for solving various nutrition problems.

    Ren, Fenggang; Zhu, Haoyang; Yan, Xiaopeng; Liu, Chang; Zhang, Xiaogang; Lv, Yi


    Liver transplantation is the only way to treat end-stage liver disease. In order to overcome the shortage of donor, marginal donors have been used widely, which bring about a series of problems. Machine perfusion can stimulate the circulation in vivo and is beneficial for the protection of liver. It could also improve the graft function and reduce postoperative complications, which makes it a hot spot in recent years. The aim of this study is to summarize the current status and prospects of application of machine perfusion on clinical liver transplantation.

    Adult-to-adult living donors and recipients were studied to characterize patterns of liver growth and identify associated factors in a multicenter study. Three hundred and fifty donors and 353 recipients in the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) receiving transplants between March 2003 and February 2010 were included. Potential predictors of 3-month liver volume included total and standard liver volumes (TLV and SLV), Model for End-Stage Liver Disease (MELD) score (in recipients), the remnant and graft size, remnant-to-donor and graft-to-recipient weight ratios (RDWR and GRWR), remnant/TLV, and graft/SLV. Among donors, 3-month absolute growth was 676 ± 251 g (mean ± SD), and percentage reconstitution was 80% ± 13%. Among recipients, GRWR was 1.3% ± 0.4% (8 Graft weight was 60% ± 13% of SLV. Three-month absolute growth was 549 ± 267 g, and percentage reconstitution was 93% ± 18%. Predictors of greater 3-month liver volume included larger patient size (donors and recipients), larger graft volume (recipients), and larger TLV (donors). Donors with the smallest remnant/TLV ratios had larger than expected growth but also had higher postoperative bilirubin and international normalized ratio at 7 and 30 days. In a combined donor-recipient analysis, donors had smaller 3-month liver volumes than recipients adjusted for patient size, remnant or graft volume, and TLV or SLV (P = 0.004). Recipient graft failure in the first 90 days was predicted by poor graft function at day 7 (HR = 4.50, P = 0.001) but not by GRWR or graft fraction (P > 0.90 for each). Both donors and recipients had rapid yet incomplete restoration of tissue mass in the first 3 months, and this confirmed previous reports. Recipients achieved a greater percentage of expected total volume. Patient size and recipient graft volume significantly influenced 3-month volumes. Importantly, donor liver volume is a critical predictor

  18. [Treatment of hepatitis C before and after liver transplantation]. (United States)

    Llovet, Laura-Patricia; Rodríguez-Tajes, Sergio; Londoño, María-Carlota


    Hepatitis C recurrence after liver transplantation is universal and increases morbidity and mortality in these patients. The development of new direct antiviral agents against the hepatitis C virus is a major treatment advance. Pre-transplant treatment avoids graft infection and sometimes improves liver function, allowing the patient to be withdrawn from the transplant waiting list. Delaying treatment until the postpostransplant period may be advisable in patients with advanced cirrhosis. Generally, antiviral therapy after liver transplantation is provided in patients with histological evidence of the disease. In these patients, treatment is more effective in the initial stages of the disease. The choice of antiviral therapy in these patients is based on the degree of liver function, the presence of renal failure, and potential drug-drug interactions.

  1. Warm vs. cold perfusion techniques to rescue rodent liver grafts. (United States)

    Schlegel, Andrea; Kron, Philipp; Graf, Rolf; Dutkowski, Philipp; Clavien, Pierre-Alain


    A variety of liver perfusion techniques have been proposed to protect liver grafts prior to implantation. We compared hypothermic and normothermic oxygenated perfusion techniques in a rat liver transplant model, using higher risk grafts obtained after cardiac arrest (DCD). Rat livers were subjected to 30 or 60 min in situ warm ischemia, without application of heparin. Livers were excised and stored for 4 h at 4°C, mimicking DCD organ procurement, followed by conventional organ transport. In experimental groups, DCD liver grafts received a 4 h normothermic oxygenated perfusion through the portal vein and the hepatic artery instead of cold storage. The perfusate consisted of either full blood or leukocyte-depleted blood (normothermic groups). Other livers underwent hypothermic oxygenated perfusion (HOPE) for 1 h after warm ischemia and 4 h cold storage (HOPE group). Liver injury was assessed during machine perfusion and after isolated liver reperfusion, and by orthotopic liver transplantation (OLT). DCD livers, subjected to normothermic perfusion, disclosed reduced injury and improved survival compared to cold storage after limited warm ischemia of 30 min (70%; 7/10), but failed to protect from lethal injury in grafts exposed to 60 min warm ischemia (0%; 0/10). This finding was consistent with Kupffer and endothelial cell activation in cold stored and normothermic perfused livers. In contrast, HOPE protected from hepatocyte and non-parenchymal cell injury and led to 90% (9/10) and 63% (5/8) animal survival after 30 and 60 min of donor warm ischemia, respectively. This is the first evidence that HOPE is superior to normothermic oxygenated perfusion in a clinically relevant model through modulation of the innate immunity and endothelial cell activation.

  2. Fontan completion in a patient with previous liver transplantation. (United States)

    Haida, Hirofumi; Aeba, Ryo; Hoshino, Ken; Morikawa, Yasuhide


    We present the first case of a successful Fontan completion in a patient with previous liver transplantation. An infant with polysplenia syndrome with a functional single ventricle and biliary atresia had been surgically managed by pulmonary artery banding, Kasai operation and living donor liver transplantation. Subsequently, the patient successfully underwent bidirectional cavopulmonary shunt and total cavopulmonary connection with extracardiac conduit at 3 and 5 years of age, respectively.

  3. Three-dimensional print of a liver for preoperative planning in living donor liver transplantation. (United States)

    Zein, Nizar N; Hanouneh, Ibrahim A; Bishop, Paul D; Samaan, Maggie; Eghtesad, Bijan; Quintini, Cristiano; Miller, Charles; Yerian, Lisa; Klatte, Ryan


    The growing demand for liver transplantation and the concomitant scarcity of cadaveric livers have increased the need for living donor liver transplantation (LDLT). Ensuring the safety of donors and recipients is critical. The preoperative identification of the vascular and biliary tract anatomy with 3-dimensional (3D) printing may allow better preoperative surgical planning, avert unnecessary surgery in patients with potentially unsuitable anatomy, and thereby decrease the complications of liver transplant surgery. We developed a protocol and successfully 3D-printed synthetic livers (along with their complex networks of vascular and biliary structures) replicating the native livers of 6 patients: 3 living donors and 3 respective recipients who underwent LDLT. To our knowledge, these are the first complete 3D-printed livers. Using standardized preoperative, intraoperative, and postoperative assessments, we demonstrated identical anatomical and geometrical landmarks in the 3D-printed models and native livers.

    Most countries exclude human immunodeficiency virus (HIV)-positive patients from organ donation because of concerns regarding donor-derived HIV transmission. The Swiss Federal Act on Transplantation has allowed organ transplantation between HIV-positive donors and recipients since 2007. We report the successful liver transplantation from an HIV-positive donor to an HIV-positive recipient. Both donor and recipient had been treated for many years with antiretroviral therapy and harbored multidr...

  5. Physical activity and metabolic syndrome in liver transplant recipients. (United States)

    Kallwitz, Eric R; Loy, Veronica; Mettu, Praveen; Von Roenn, Natasha; Berkes, Jamie; Cotler, Scott J


    There is a high prevalence of metabolic syndrome in liver transplant recipients, a population that tends to be physically inactive. The aim of this study was to characterize physical activity and evaluate the relationship between physical activity and metabolic syndrome after liver transplantation. A cross-sectional analysis was performed in patients more than 3 months after transplantation. Metabolic syndrome was classified according to National Cholesterol Education Panel Adult Treatment Panel III guidelines. Physical activity, including duration, frequency, and metabolic equivalents of task (METs), was assessed. The study population consisted of 204 subjects, with 156 more than 1 year after transplantation. The median time after transplantation was 53.5 months (range = 3-299 months). The mean duration of exercise was 90 ± 142 minutes, and the mean MET score was 3.6 ± 1.5. Metabolic syndrome was observed in 58.8% of all subjects and in 63.5% of the subjects more than 1 year after transplantation. In a multivariate analysis involving all subjects, metabolic syndrome was associated with a time after transplantation greater than 1 year [odds ratio (OR) = 2.909, 95% confidence interval (CI) = 1.389-6.092] and older age (OR = 1.036, 95% CI = 1.001-1.072). A second analysis was performed for only patients more than 1 year after transplantation. In a multivariate analysis, metabolic syndrome was associated with lower exercise intensity (OR = 0.690, 95% CI = 0.536-0.887), older age (OR = 1.056, 95% CI = 1.014-1.101), and pretransplant diabetes (OR = 4.246, 95% CI = 1.300-13.864). In conclusion, metabolic syndrome is common after liver transplantation, and the rate is significantly higher in patients more than 1 year after transplantation. The observation that exercise intensity is inversely related to metabolic syndrome after transplantation is novel and suggests that physical activity might provide a means for reducing metabolic syndrome complications in liver

    Interventional radiology has acquired a key role in every liver transplantation (LT) program by treating the majority of vascular and non-vascular post-transplant complications, improving graft and patient survival and avoiding, in the majority of cases, surgical revision and/or re-transplantation. The aim of this paper is to review indications, technical consideration, results achievable and potential complications of interventional radiology procedures after deceased donor LT and living related adult LT.

  7. Intraportal islet transplantation: the impact of the liver microenvironment. (United States)

    Delaune, Vaihere; Berney, Thierry; Lacotte, Stéphanie; Toso, Christian


    The portal vein remains the preferred site for pancreatic islet transplantation due to its easy access and low morbidity. However, despite great progress in isolation and transplantation protocols over the past few years, it is still associated with the early loss of some 50-70% of transplanted islets. The complex liver microenvironment itself presumably plays an important role in this loss. The present review focuses on the specifics of the liver microenvironment, notably the localized hepatic ischemia/reperfusion injury following transplantation, the low oxygenation of the portal vein, the instant blood-mediated inflammatory reaction, the endogenous liver immune system, and the gut-liver axis, and how they can each have an impact on the transplanted islets. It identifies the potential, or already applied, clinical interventions for improving intraportal islet survival, and pinpoints those promising areas still lacking preclinical research. Future interventions on clinical intraportal islet transplantation need to take into account the global context of the liver microenvironment, with multi-point interventions being most likely to improve early islet survival and engraftment. © 2017 The Authors.

  8. Liver transplantation in the management of unresectable hepatoblastoma in children. (United States)

    Meyers, Rebecka L; Tiao, Greg M; Dunn, Stephen P; Langham, Max R


    Complete surgical resection is essential to long-term survival in children with hepatoblastoma. We present the guidelines from the Children's Oncology Group (COG), liver tumor study group of the Societe Internationale Oncologie Pediatrique (SIOPEL), and German Pediatric Oncology Group (GPOH) for early referral of children with potentially unresectable hepatoblastoma to a specialty center with expertise in extreme resection and liver transplantation. Patients who will become candidates for liver transplantation should receive chemotherapy following the same protocols as for children undergoing a partial hepatectomy. The Pediatric Liver Unresectable Tumor Observatory (PLUTO) is an international prospective database established to collect data and make future recommendations on controversial issues regarding the use of transplant in hepatoblastoma including: 1) What is the optimal treatment of multifocal tumors. 2) What is the role of extreme resection vs. liver transplant in patients with major venous involvement. 3) What is the role of transplant in patients who present with lung metastasis. 3) Should patients with tumor relapse be offered a rescue transplant. 4) What is the role of pre- and post- transplant chemotherapy.

    Full Text Available Madeleine Oliver,1 Christopher Chiodo Ortiz,2 Jorge Ortiz31University of Toledo College of Medicine, Toledo, OH, 2Bucknell University, Lewisburg, PA, 3Department of Transplant Surgery, University of Toledo Medical Center, Toledo, OH, USA Abstract: Caring for liver transplant patients suffering from chronic hepatitis C virus (HCV infection is a challenging task for transplant surgeons and primary physicians alike. HCV is the leading cause of liver transplantation in the USA and comes with a myriad of complications that increase morbidity and mortality. This review focuses on patient follow-up, spanning from before the liver transplant occurs to the patient's long-term health. Pretransplant, both donor and recipient variables, must be carefully chosen to ensure optimal surgical success. Risk factors must be identified and HCV viral load must be reduced to a minimum. In addition to standard transplant complications, HCV patients suffer from additional problems, such as fibrosing cholestatic hepatitis and widespread viremia. Physicians must focus on the balance of immunosuppressive and antiviral medications, while considering possible side effects from these potent drugs. Over the years following surgery, physicians must identify any signs of failing liver health, as HCV-positive patients have an increased risk for cirrhosis and certain life-threatening malignancies.

    One of the most important problems after solid organ transplantation including liver, remains infections. Multiple risk factors play a role among which the most important are: general patients health before transplantation, prolong operative time, graft function and type of immunosuppression. The most important problems with bacterial, fungal and viral infections was described as well as treatment and profilaxis.

  11. Low predictive value of polymerase chain reaction for diagnosis of cytomegalovirus disease in liver transplant recipients. (United States)

    Delgado, R; Lumbreras, C; Alba, C; Pedraza, M A; Otero, J R; Gómez, R; Moreno, E; Noriega, A R; Payá, C V


    The polymerase chain reaction (PCR) and viral culture techniques were prospectively compared for the detection of cytomegalovirus (CMV) in blood samples from 24 liver transplant recipients. Nine patients had one or more episodes of viremia, seven of which were clinically symptomatic infections. All samples in which CMV was isolated by culture were positive by the PCR. However, the PCR result was also positive for one or more samples from 11 patients who never developed CMV-related symptoms. Although the PCR is a very sensitive technique for CMV detection in blood samples from liver transplant recipients, it is not useful as a marker of symptomatic CMV disease.

  13. Liver transplantation in PBC and PSC: indications and disease recurrence. (United States)

    Carbone, Marco; Neuberger, James


    Primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) represent major indications for liver transplantation (LT). Despite the steady increase in the incidence and prevalence of PBC, the number of liver transplants for PBC has fallen in recent years, whereas the number of transplants for PSC has remained stable. Indications for LT for PBC and PSC are no different from those of other causes of chronic liver disease, apart from some disease-specific indications. PBC and PSC have more favourable outcomes after LT, compared to viral hepatitis and alcohol-associated liver disease. Numerous studies have clearly demonstrated that PBC and PSC recur after LT. The diagnosis of recurrent disease should be made on agreed criteria. The impact of recurrent disease on survival is unclear. Study of recurrent PBC and PSC may provide a better understanding of the mechanisms of these diseases in the native liver.

  14. Cardiac Failure after Liver Transplantation Requiring a Biventricular Assist Device

    Directory of Open Access Journals (Sweden)

    Rita Jermyn


    Full Text Available Increased hepatic iron load in extrahepatic organs of cirrhotic patients with and without hereditary hemochromatosis portends a poorer long term prognosis after liver transplant. Hepatic as well as nonhepatic iron overload is associated with increased infectious and postoperative complications, including cardiac dysfunction. In this case report, we describe a cirrhotic patient with alpha 1 antitrypsin deficiency and nonhereditary hemochromatosis (non-HFE that developed cardiogenic shock requiring mechanical circulatory support for twenty days after liver transplant. Upon further investigation, she was found to have significant iron deposition in both the liver and heart biopsies. Her heart regained complete and sustained recovery following ten days of mechanical biventricular support. This case highlights the importance of preoperatively recognizing extrahepatic iron deposition in patients referred for liver transplantation irrespective of etiology of liver disease as this may prevent postoperative complications.

    Liver cell transplantation is an attractive technique to treat liver-based inborn errors of metabolism. The feasibility and efficacy of the procedure has been demonstrated, leading to medium term partial metabolic control of various diseases. CriglerNajjar is the paradigm of such diseases in that the host liver is lacking one function with an otherwise normal parenchyma. The patient is at permanent risk for irreversible brain damage. The goal of liver cell transplantation is to reduce serum bilirubin levels within safe limits and to alleviate phototherapy requirements to improve quality of life. Preliminary data on Gunn rats, the rodent model of the disease, were encouraging and have led to successful clinical trials. Herein we report on two additional patients and describe the current limits of the technique in terms of durability of the response as compared to alternative therapeutic procedures. We discuss the future developments of the technique and new emerging perspectives.

    BACKGROUND:When liver or kidney transplant can respectively cure end-stage liver or kidney disease, neither hepatic graft nor renal transplant alone can be used as a radical therapy for diseases which involve both liver and kidney. Combined liver and kidney transplantation commenced late in China, and the number of transplants has been limited. This study was designed to assess the effects of simultaneous combined liver and kidney transplantation (SLKT) on end-stage liver and kidney diseases. METHODS:Fifteen patients who had received SLKT from 1996 to 2006 in the First Afifliated Hospital of Sun Yat-Sen University were reviewed. They included 5 patients with polycystic liver and kidney, 5 patients with hepatic cirrhosis and renal failure, and 5 patients with fulminant hepatic failure and hepatorenal syndrome (11 men and 4 women; average age 43.5 years). All patients had combined liver and kidney transplantation. RESULTS:The 5 patients with polycystic liver and kidney have survived for more than one year after SLKT, and the longest survival has been 5 years. Three of the 5 patients with hepatic cirrhosis and renal failure have survived more than two years; one died perioperatively and the other died from recurrence of hepatitis B 18 months after the operation. Three of the 5 patients with fulminant hepatic failure and hepatorenal syndrome have survived for two years, and 2 died of multiple organ failure during the operation.CONCLUSIONS:SLKT is an effective therapy for end-stage liver and kidney disease but the indications of SLKT for hepatorenal syndrome should be strict. SLKT may immunologically protect the renal graft.

  17. Societal reintegration following cadaveric orthotopic liver transplantation. (United States)

    Kelly, Ryan; Hurton, Scott; Ayloo, Subhashini; Cwinn, Mathew; De Coutere-Bosse, Sarah; Molinari, Michele


    Studies on patients' societal reintegration following orthotopic liver transplantation (OLT) are scarce. Between September 2006 and January 2008, all adults who were alive after 3 years post OLT were included in this prospective cohort study. Validated questionnaires were administered to all candidates with the primary aim of investigating the rate of their social re-integration following OLT and potential barriers they might have encountered. Among 157 eligible patients 110 (70%) participated. Mean participants' age was 57 years (SD 11.4) and 43% were females. Prior to OLT, 75% of patients were married and 6% were divorced. Following OLT there was no significant difference in marital status. Employment rate fell from 72% to 30% post-OLT. Patients who had been employed in either low-skill or advanced-skill jobs were less likely to return to work. After OLT, personal income fell an average of 4,363 Canadian dollars (CAN$) (SD 20,733) (P=0.03) but the majority of recipients (80%) reported high levels of satisfaction for their role in society. Although patients' satisfaction post-OLT is high, employment status is likely to be negatively affected for individuals who are not self-employed. Strategies to assist recipients in returning to their pre-OLT jobs should be developed to improve patients' economical status and societal ability to recoup resources committed for OLT.

  18. Recipient-derived hepatocytes in liver transplants: a rare event in sex-mismatched transplants. (United States)

    Fogt, Franz; Beyser, Kurt H; Poremba, Christopher; Zimmerman, Robert L; Khettry, Urmila; Ruschoff, Josef


    Bone marrow-derived stem cells have been shown to engraft and populate native tissues during repair and in transplanted animal tissues. Very few studies have been performed in humans to evaluate the possibility of stem cell engraftment in transplanted tissues. In human renal transplants, recipient cells have been demonstrated within vascular and interstitial structures. In a previous study of patients with hepatic transplants, hepatocytes with XY chromosome patterns have been detected in sex-mismatched female to male transplanted livers in a small number of cases. Because of the possibility of Y chromosome microchimerism of females with male offspring, we analyzed the presence of X and Y chromosomes in liver biopsies of 13 patients with sex-mismatched liver transplants (8 female to male, 5 male to female) and long transplant to biopsy intervals (1.2 to 12 years; mean, 4.5 years). We were able to detect recipient-specific sex chromosomal patterns in inflammatory cells by fluorescent in situ hybridization/immunohistochemistry combination within the liver parenchyma but not within hepatocytes. In conclusion, recipient engraftment of stem cells may be an early feature in liver transplant but may be an infrequent persistent feature in long-term grafts.

  19. Calcinosis cutis following liver transplantation in a pediatric patient. (United States)

    Larralde, Margarita; Giachetti, Ana; Kowalczuk, Alicia; D'Agostino, Daniel; Galimberti, Ricardo


    We report the occurrence of calcinosis cutis in a 3-year-old girl after liver transplantation. The cutaneous lesions consisted of 5 mm white papules on an erythematous base in linear and rosette configurations that developed in the abdominal and lumbar areas 10 days after transplantation. The patient had received calcium chloride solution intravenously during surgery. We excluded other causes of ectopic calcification such as hyperparathyroidism, renal failure, and extravasation of calcium solution. We discuss the etiology of calcinosis cutis after liver transplantation. This sequence of events has not been previously described in pediatric patients.

    Liver transplantation (LT) in patients with portopulmonary hypertension (PoPH) has historically resulted in unpredictable and often poor outcomes. The United Kingdom experience for the period 1992-2012 is reported in this article. A retrospective analysis of patients, preoperatively fulfilling the PoPH European Respiratory Society Task Force on Pulmonary-Hepatic Vascular Disorders diagnostic criteria was conducted across all UK LT centers. Data collection included comorbidities, use of preoperative and postoperative pharmacotherapy, patient survival, and cause of death. To enable survival stratification, PoPH was classified as mild, moderate, or severe based on mean pulmonary pressure of consideration to transplant. Liver Transplantation 22 1637-1642 2016 AASLD.

  1. Successful Domino Liver Transplantation from a Patient with Methylmalonic Acidemia. (United States)

    Khanna, A; Gish, R; Winter, S C; Nyhan, W L; Barshop, B A


    Liver transplantation has been reported in patients with methylmalonic acidemia (MMA), but long-term outcome is controversial. Many patients with other approved indications for liver transplantation die before donor grafts are available. A 28-year-old man with MMA underwent cadaveric liver transplantation. His liver was used as a domino graft for a 61-year-old man with primary sclerosing cholangitis, who had low priority on the transplant waiting list. Surgical outcome was successful, and after transplantation both patients have excellent graft function. The patient with MMA showed substantial decrease in methylmalonate in urine (from 5,277 ± 1,968 preoperatively to 1,068 ± 384 mmol/mol creatinine) and plasma (from 445.9 ± 257.0 to 333.3 ± 117.7 μmol/l) over >1-year follow-up, while dietary protein intake increased from 0.6 to 1.36 ± 0.33 g/kg/day. The domino recipient maintained near-normal levels of plasma amino acids but did develop elevated methylmalonate in blood and urine while receiving an unrestricted diet (peak plasma methylmalonate 119 μmol/l and urine methylmalonate 84-209 mmol/mol creatinine, with 1.0-1.9 g/kg/day protein). Neither patient demonstrated any apparent symptoms of MMA or metabolic decompensation during the postoperative period or following discharge. Liver transplantation substantially corrects methylmalonate metabolism in MMA and greatly attenuates the disease. In this single patient experience, a liver from a patient with MMA functioned well as domino graft although it did result in subclinical methylmalonic acidemia and aciduria in the recipient. Patients with MMA can be considered as domino liver donors for patients who might otherwise spend long times waiting for liver transplantation.

  2. Liver steatosis in pre-transplant liver biopsies can be quantified rapidly and accurately by nuclear magnetic resonance analysis. (United States)

    Bertram, Stefanie; Myland, Cathrin; Swoboda, Sandra; Gallinat, Anja; Minor, Thomas; Lehmann, Nils; Thie, Michael; Kälsch, Julia; Pott, Leona; Canbay, Ali; Bajanowski, Thomas; Reis, Henning; Paul, Andreas; Baba, Hideo A


    Donor livers marginally acceptable or acceptable according to extended criteria are more frequently transplanted due to the growing discrepancy between demand and availability of donor organs. One type of marginally acceptable graft is a steatotic donor liver, because it is more sensitive to ischemia-reperfusion injury. Thus, quantitative assessment of steatosis is crucial prior to liver transplantation. Extent of steatosis of 49 pre-reperfusion liver biopsies from patients who received orthotopic liver transplantation was assessed by three techniques: semi-quantitative histological evaluation, computerized histomorphometry, and NMR-based estimation of fat content. The findings were correlated to clinical data and to histological examination of corresponding post-reperfusion biopsies for quantification of ischemia-reperfusion injury. We found that values obtained through all three assessment methods were positively correlated. None of the values obtained by the three applied methods correlated with clinical outcome or extent of ischemia-reperfusion injury. Quantitative evaluation of steatosis by NMR yields results comparable to histological and morphometrical assessment. This technique is rapid (livers, and provides results that can be used when evaluation by a pathologist is not available.

    Living donor liver transplant(LDLT)is a major surgi-cal undertaking.Detailed pre-operative assessment of the vascular and biliary anatomy is crucial for safe and successful harvesting of the graft and transplantation.Computed tomography(CT)and magnetic resonance imaging(MRI)are currently the imaging modalities of choice in pre-operative evaluation.These cross-sec-tional imaging techniques can reveal the vascular and biliary anatomy,assess the hepatic parenchyma and perform volumetric analysis.Knowledge of the broad indications and contraindications to qualify as a recipi-ent for LDLT is essential for the radiologist reporting scans in a pre-transplant patient.Similarly,awareness of the various anatomical variations and pathological states in the donor is essential for the radiologist to generate a meaningful report of his/her observations.CT and MRI have largely replaced invasive techniques such as catheter angiography,percutaneous cholan-giography and endoscopic retrograde cholangiopan-creatography.In order to generate a meaningful report based on these pre-operative imaging scans,it is also mandatory for the radiologist to be aware of the sur-geon’s perspective.We intend to provide a brief over-view of the common surgical concepts of LDLT and give a detailed description of the minimum that a radiologist is expected to seek and report in CT and MR scans per-formed for LDLT related evaluation.

  4. Establishment of animal model of dual liver transplantation in rat.

    Directory of Open Access Journals (Sweden)

    Ying Zhang

    Full Text Available The animal model of the whole-size and reduced-size liver transplantation in both rat and mouse has been successfully established. Because of the difficulties and complexities in microsurgical technology, the animal model of dual liver transplantation was still not established for twelve years since the first human dual liver transplantation has been made a success. There is an essential need to establish this animal model to lay a basic foundation for clinical practice. To study the physiological and histopathological changes of dual liver transplantation, "Y" type vein from the cross part between vena cava and two iliac of donor and "Y' type prosthesis were employed to recanalize portal vein and the bile duct between dual liver grafts and recipient. The dual right upper lobes about 45-50% of the recipient liver volume were taken as donor, one was orthotopically implanted at its original position, the other was rotated 180° sagitally and heterotopically positioned in the left upper quadrant. Microcirculation parameters, liver function, immunohistochemistry and survival were analyzed to evaluate the function of dual liver grafts. No significant difference in the hepatic microcirculatory flow was found between two grafts in the first 90 minutes after reperfusion. Light and electronic microscope showed the liver architecture was maintained without obvious features of cellular destruction and the continuity of the endothelium was preserved. Only 3 heterotopically positioned graft appeared patchy desquamation of endothelial cell, mitochondrial swelling and hepatocytes cytoplasmic vacuolization. Immunohistochemistry revealed there is no difference in hepatocyte activity and the ability of endothelia to contract and relax after reperfusion between dual grafts. Dual grafts made a rapid amelioration of liver function after reperfusion. 7 rats survived more than 7 days with survival rate of 58.3.%. Using "Y" type vein and bile duct prosthesis, we

    BACKGROUND: The discrepancy between available livers and requests for transplantation has forced many centers to use marginal donors in order to expand the donor pool. Many previous studies have demonstrated controversial results of the application of steatotic liver grafts. The aim of the present study was to summarize our experience and evaluate the value of steatotic liver grafts. METHODS: The clinical and follow-up data of 24 adult patients receiving moderately steatotic liver grafts (30%-60%) from May 2003 to June 2005 (group 1) were analyzed. After matching for age, gender, model for end-stage liver diseases score and cold ischemia time, another 24 patients receiving liver grafts with steatosis less than 30%were chosen as the control group (group 2). The patient and graft outcomes were compared between the two groups. RESULTS: No difference of liver and kidney functions in the ifrst post-transplant week was found between the two groups (P>0.05). Neither the incidence of early allograft dysfunction and acute kidney injury nor the patient survival rates (3 months, 6 months and 1 year) showed differences between groups 1 and 2 (P>0.05). CONCLUSION: Moderately steatotic liver grafts provide adequate function in the ifrst phase after transplantation and can be used for transplantation.

    Soung Won Jeong


    Full Text Available Recurrence of viral hepatitis after liver transplantation (LT can progress to graft failure and lead to a decrease in long-term survival. Recently, there have been remarkable improvement in the treatment of chronic hepatitis B (CHB using potent antiviral agents. Combination of hepatitis B immunoglobulin and potent antiviral therapy has brought marked advances in the management of CHB for liver transplant recipients. Post-transplant antiviral therapy for hepatitis C virus infection is generally reserved for patients showing progressive disease. Acheiving a sustained virological response in patients with LT greatly ameliorates graft and overall survival, however this only occurs in 30% of transplant recipient using pegylated interferon and ribavirin (RBV. Direct acting antivirals such as protease inhibitors, polymerase or other non-structural proteins inhibitors are anticipated to establish the new standard of care for transplant recipients. In liver transplant recipients, hepatitis E virus infection is an uncommon disease. However, it can lead to chronic hepatitis and cirrhosis and may require retransplantation. Recently, 3-month course of RBV monotherapy has been reported as an effective treatment. This review focuses on the recent management and therapeutic approaches of viral hepatitis in liver transplant recipient.

  9. Spontaneous Clearance of Hepatitis C after Liver and Renal Transplantation

    Directory of Open Access Journals (Sweden)

    CH Dale


    Full Text Available Spontaneous clearance of hepatitis C virus (HCV is rare in immunocompromised patients, such as those who have undergone organ transplantation. It has been recognized that patients receiving liver transplantation for HCV-related disease have decreased graft and patient survival compared with those transplanted for other etiologies. There is a growing trend toward treating HCV recurrence aggressively after liver transplantation. For other organ transplant recipients with concurrent HCV, treatment is not often an option, given the high rates of graft rejection and loss secondary to interferon and its immunomodulatory effects. Although spontaneous clearance of HCV has been reported in recipients of solitary liver and renal transplants, a common factor arising in these cases has been previous exposure to interferon. To date, no reports of spontaneous clearance of HCV RNA have been reported in a multiorgan transplant recipient. A case of spontaneous clearance of HCV RNA in an immunocompromised patient, within five months of simultaneous liver and kidney retransplantation is described. Importantly, this patient had no previous exposure to interferon.

    Background Liver transplantation is the most effective treatment for end-stage liver diseases;however,infections after transplantation can seriously affect the patient's health. The aim of this research was to investigate the diagnosis and treatment of fungal infection following liver transplantation.Methods Clinical data for 232 liver transplant patients at risk of fungal infection were examined for the presence of fungus in the blood,fluid,sputum,urine and stools of patients and by chest or abdominal CT scans. Patients diagnosed with a fungal infection were treated with Fluconazole or,if this was not effective,Voriconazole or Amphotericin B.Immunosuppressive therapy was also reviewed.Results Thirty-seven of 232 (15.9%) patients were diagnosed with a fungal infection,which occurred 4 to 34 days post-transplantation. Candida infections were diagnosed in 23 cases (62.2%) and Aspergillus infections in 12 cases (32.4%). Twenty-one cases were effectively treated with Fluconazole,11 cases with Voriconazole,and two cases with Amphotericin B;however,three cases were not effectively treated with any of the antifungal agents. Overall,treatment was effective in 91.9% of patients.Conclusions Fungal infection has a significant influence on survival rate after liver transplantation. Imaging studies,and pathogenic and biopsy examinations can diagnose fungal infections,which can be effectively treated with antifungal agents such as Fluconazole,Voriconazole or Amphotericin B.

  11. Liver-kidney transplantation to cure atypical hemolytic uremic syndrome. (United States)

    Saland, Jeffrey M; Ruggenenti, Piero; Remuzzi, Giuseppe


    Atypical hemolytic uremic syndrome is often associated with mutations in genes encoding complement regulatory proteins and secondary disorders of complement regulation. Progression to kidney failure and recurrence with graft loss after kidney transplantation are frequent. The most common mutation is in the gene encoding complement factor H. Combined liver-kidney transplantation may correct this complement abnormality and prevent recurrence when the defect involves genes encoding circulating proteins that are synthesized in the liver, such as factor H or I. Good outcomes have been reported when surgery is associated with intensified plasma therapy. A consensus conference to establish treatment guidelines for atypical hemolytic uremic syndrome was held in Bergamo in December 2007. The recommendations in this article are the result of combined clinical experience, shared research expertise, and a review of the literature and registry information. This statement defines groups in which isolated kidney transplantation is extremely unlikely to be successful and a combined liver-kidney transplant is recommended and also defines those for whom kidney transplant remains a viable option. Although combined liver-kidney or isolated liver transplantation is the preferred therapeutic option in many cases, the gravity of risk associated with the procedure has not been eliminated completely, and assessment of risk and benefit requires careful and individual attention.

    Emerson Seiberlich


    Full Text Available INTRODUCTION: Liver transplantation is the best therapeutic option for end-stage liver disease. Non-selective beta-blocker medications such as propranolol act directly on the cardiovascular system and are often used in the prevention of gastrointestinal bleeding resulting from HP. The effects of propranolol on cardiovascular system of cirrhotic patients during liver transplantation are not known. OBJECTIVE: Evaluate the influence of propranolol used preoperatively on cardiac index during the anhepatic phase of liver transplantation. METHOD: 101 adult patients (73 male [72.2%] who underwent cadaveric donor orthotopic liver transplantation by piggyback technique with preservation of the retrohepatic inferior vena cava performed at Hospital das Clinicas, Federal University of Minas Gerais were evaluated. There was no difference in severity between groups by the MELD system, p = 0.70. The preoperative use of propranolol and the cardiac index outcome were compared during the anhepatic phase of liver transplantation in 5 groups (I: increased cardiac index, II: cardiac index reduction lower than 16%, III: cardiac index reduction equal to or greater than 16% and less than 31%, IV: cardiac index reduction equal to or greater than 31% and less than 46%, V: cardiac index reduction equal to or greater than 46%. RESULTS: Patients in group I (46.4% who received propranolol preoperatively were statistically similar to groups II (60%, III (72.7%, IV (50% and V (30.8%, p = 0.57. CONCLUSION: The use of propranolol before transplantation as prophylaxis for gastrointestinal bleeding may be considered safe, as it was not associated with worsening of cardiac index in anhepatic phase of liver transplantation.

  13. Non-invasive measurement of hepatic oxygenation by an oxygen electrode in human orthotopic liver transplantation. (United States)

    Seifalian, A M; Mallett, S; Piasecki, C; Rolles, K; Davidson, B R


    Precise evaluation of graft reperfusion is difficult in clinical liver transplantation. The oxygen electrode (OE) is a novel technique to detect blood flow indirectly by measuring the quantity of oxygen which can diffuse from the hepatic tissue to the surface electrode. Application of the surface OE does not influence the liver blood flow or parenchymal perfusion. Adequate graft oxygenation is essential to the outcome of organ transplantation and has not previously been analysed intra-operatively in liver transplant recipients. The OE was applied to the surface of the graft intra-operatively in 22 human liver grafts after restoring portal vein and hepatic artery inflow. OE readings were compared with liver blood flow using an electromagnetic flowmeter (EMF). Intra-operative haemodynamics and donor organ parameters known to influence graft function were correlated with the OE readings. There was a significant correlation (r=0.89; poxygenation using the OE and total liver blood flow measured by EMF. The tissue oxygenation measurements were reproducible with a coefficient of variation of 5%. The hepatic tissue oxygenation increased significantly from baseline following venous reperfusion of the graft (282+/-23 vs 3107+/-288 (+/-SE) nA, poxygen perfusion. There was significant negative correlation (r=0.80, poxygenation. The OE provides a reliable, cheap and non-invasive method of monitoring liver graft oxygenation and perfusion during transplantation.

    AIM: To introduce combined liver-small bowel transplantation in pigs.METHODS: Eighteen transplantations in 36 large white pigs were performed. Three modifications in combined liver-small bowel transplantation model were applied: Veno-venous bypass was not used. Preservation of the donor duodenum and head of pancreas in continuity with the combined graft to avoid biliary reconstruction. The splenic vein of donor was anastomosed end-to-end with the portal vein of recipients by the formation of a "cuff".RESULTS: Without immunosuppressive therapy, 72-hour survival rate of the transplanted animals was 72% (13/18).Five of 18 pigs operated died of respiratory failure (3 cases)and bleeding during hepatectomy (2 cases). The longest survival time of animals was 6 days.CONCLUSION: Our surgical modifications are feasible and reliable, which have made the transplantation in pigs simpler and less aggressive, and thus these can be used for preclinical study.

    Objective To assess the information needs of family caregivers of candidates on the waiting list for a liver transplant. Methods It is a cross-sectional study conducted in a transplant center in São Paulo State in the period between April and October of 2012. For the assessment of information needed, an instrument submitted to face and content value was used. The caregivers put 10 subjects in order according to their importance and the amount of interest they had in learning about each, prior to the transplant their family member would be subjected to. Sociodemographic characteristics were also recorded. For data analysis, descriptive statistics were used. Results 42 families participated in the study. The information need about liver disease complications, complications after transplantation and care needed after surgery had higher averages. Conclusions Knowing the information needs of caregivers is important to plan teaching-learning strategies aimed at improving assistance to patients and families in transplant programs.

  16. Cystic Liver Infection after Living Donor Liver Transplantation: A Case Report

    Directory of Open Access Journals (Sweden)

    Kensuke Kudou


    Full Text Available There are no reports of cystic liver infection after liver transplantation. Herein, we report a rare case of cystic liver graft infection after living donor liver transplantation (LDLT. The patient was a 24-year-old man with primary sclerosing cholangitis who underwent right lobe graft LDLT. Preoperative abdominal computed tomography (CT revealed a liver cyst at segment 8 of the donor liver. Biliary reconstruction was performed with hepaticojejunostomy. The postoperative course was uneventful until the patient developed a high fever and abdominal pain 15 months after LDLT. Abdominal contrast CT revealed abscess formation. Percutaneous drainage of the cyst was performed and purulent liquid was drained. The fever gradually subsided after treatment. On follow-up CT, the size of the infected liver cyst was decreased. Clinicians should be aware of the potential for cystic liver infection when using grafts with liver cysts, particularly when biliary reconstruction is performed with hepaticojejunostomy.

  17. Perceptions of post-transplant recidivism in liver transplantation for alcoholic liver disease

    Although alcoholic liver disease(ALD) is regarded as a common indication for liver transplantation(LT), debatable issues exist on the requirement for preceding alcoholic abstinence, appropriate indication criteria, predictive factors for alcoholic recidivism, and outcomes following living-donor LT. In most institutions, an abstinence period of six months before LT has been adopted as a mandatory selection criterion. Data indicating that pre-transplant abstinence is an associated predictive factor for alcoholic recidivism supports the reasoning behind this. However, conclusive evidence about the benefit of adopting an abstinence period is yet to be established. On the other hand, a limited number of reports available on living-donor LT experiences for ALD patients suggest that organ donations from relatives have no suppressive effect on alcoholic recidivism. Prevention of alcoholic recidivism has proved to be the most important treatment after LT based on the resultant inferior long-term outcome of patients. Further evaluations are still needed to establish strategies before and after LT for ALD.

  18. Organisational structure of liver transplantation in the UK. (United States)

    Neuberger, James


    This review aims to outline the delivery of liver transplant services in the UK. Liver transplantation in the UK is based on seven designated transplant units serving a population of just over 60 million people. Nearly 900 liver transplants were done in 2013/2014. Potential deceased donors are identified and referred to centrally employed specialist nurses for obtaining family consent and for donor characterisation. Organs are retrieved by a National Organ Retrieval Service, based on seven abdominal and six cardiothoracic retrieval teams providing a 24/7 service which has shown to be capable of retrieving organs from up to ten donors a day. Donated organs are allocated first nationally to those who qualify for super-urgent listing. The next priority is for splitting livers, and if there is no suitable recipient or the liver is not suitable for splitting, then livers are offered first to the local centre; each centre has a designated donor zone, adjusted annually to ensure equity between the number of patients listed and the number of donors. The allocation scheme is being reviewed, and national schemes based on need, utility and benefit are being assessed. Outcomes are monitored by National Health Service Blood and Transplant (NHSBT), and if there is a possibility of adverse deviation, then further inquiries are made. Outcomes, both from listing and from transplantation, are published by the centre on the NHSBT website ( ). NHSBT works closely with stakeholders primarily through the advisory groups with clinicians, patients, lay members and professional societies and aims to provide openness and transparency. The system for organ donation and delivery of liver transplant in the UK has developed and is now providing an effective and efficient service, but there remains room for improvement.

  20. Fluordeoxyglucose positron emission tomography contributes to management of pediatric liver transplantation candidates with fever of unknown origin. (United States)

    Sturm, Ekkehard; Rings, Edmond H H M; Schölvinck, Elisabeth H; Gouw, Annette S H; Porte, Robert J; Pruim, Jan


    Fever of unknown origin (FUO) frequently complicates the management of pediatric patients with terminal chronic liver failure during the pretransplantation period and may lead to increased morbidity and mortality. Nonhepatic origins of systemic infections may render the patient unsuitable for transplantation whereas infections within the liver may require organ resection for a cure. Therefore, accurate localization of the infection focus is critical for optimal management of children on the waiting list for liver transplantation. Here we report our experience using [18 F]fluordeoxyglucose (FDG)-positron emission tomography (PET) to detect the origin of infection in 11 children with biliary cirrhosis presenting with FUO during the waiting period for liver transplantation. In 5 children, positive intrahepatic FDG-PET signals correlated with bacterial cultures of the excised liver and/or anatomic or histologic signs of infection. Based on the FDG-PET findings, these patients underwent transplantation after continuous antibiotic treatment with ongoing, recurrent episodes of fever. In 6 children, no abnormal hepatic FDG-PET signals were found and no infections could be detected in the liver. Transplantation in these patients was performed only after becoming afebrile. Standard imaging techniques did not reveal abnormalities compatible with infection in any of the children. In conclusion, in children with biliary cirrhosis and FUO on the waiting list for liver transplantation, information obtained by FDG-PET imaging may be useful for decisions on therapy and suitability for liver transplantation.

  1. Preservation of the recipient inferior vena cava in liver transplantation. (United States)

    Pereira, F; Herrera, J; Mora, N P; Nuño, J; Turrión, V S; Vicente, E; Ardaiz, J


    Twenty piggy-back (PB) liver transplantations (LT) were compared with 20 LT performed by the standard technique in order to evaluate whether or not the theoretical haemodynamic advantages of the preservation of the inferior vena cava (IVC) have any impact on the final results of the LT. Statistically significant differences were observed in the duration of the hepatectomy, which was longer for PB LT (192 min vs. 146 min), and in the duration of the anhepatic phase, which was shorter in that group (52 min vs. 76 min). There were no differences in the duration of the complete surgical procedure, consumption of blood products, incidence of postoperative acute renal failure, number of reoperations or survival.

    Abstract Aim and background. The Nordic Liver Transplant Registry (NLTR) accounts for all liver transplants performed in the Nordic countries since the start of the transplant program in 1982. Due to short waiting times, donor liver allocation has been made without considerations of the model of end-stage liver disease (MELD) score. We aimed to summarize key outcome measures and developments for the activity up to December 2013. Materials and methods. The registry is integrated with the operational waiting-list and liver allocation system of Scandiatransplant ( and accounted at the end of 2013 for 6019 patients out of whom 5198 were transplanted. Data for recipient and donor characteristics and relevant end-points retransplantation and death are manually curated on an annual basis to allow for statistical analysis and the annual report. Results. Primary sclerosing cholangitis, acute hepatic failure, alcoholic liver disease, primary biliary cirrhosis and hepatocellular carcinoma are the five most frequent diagnoses (accounting for 15.3%, 10.8%, 10.6%, 9.3% and 9.0% of all transplants, respectively). Median waiting time for non-urgent liver transplantation during the last 10-year period was 39 days. Outcome has improved over time, and for patients transplanted during 2004–2013, overall one-, five- and 10-year survival rates were 91%, 80% and 71%, respectively. In an intention-to-treat analysis, corresponding numbers during the same time period were 87%, 75% and 66%, respectively. Conclusion. The liver transplant program in the Nordic countries provides comparable outcomes to programs with a MELD-based donor liver allocation system. Unique features comprise the diagnostic spectrum, waiting times and the availability of an integrated waiting list and transplant registry (NLTR). PMID:25959101

  3. Non-Alcoholic Fatty Liver Disease and Metabolic Syndrome after Liver Transplant. (United States)

    Gitto, Stefano; Villa, Erica


    Liver transplant is the unique curative therapy for patients with acute liver failure or end-stage liver disease, with or without hepatocellular carcinoma. Increase of body weight, onset of insulin resistance and drug-induced alterations of metabolism are reported in liver transplant recipients. In this context, post-transplant diabetes mellitus, hyperlipidemia, and arterial hypertension can be often diagnosed. Multifactorial illnesses occurring in the post-transplant period represent significant causes of morbidity and mortality. This is especially true for metabolic syndrome. Non-alcoholic steatosis and steatohepatitis are hepatic manifestations of metabolic syndrome and after liver transplant both recurrent and de novo steatosis can be found. Usually, post-transplant steatosis shows an indolent outcome with few cases of fibrosis progression. However, in the post-transplant setting, both metabolic syndrome and steatosis might play a key role in the stratification of morbidity and mortality risk, being commonly associated with cardiovascular disease. The single components of metabolic syndrome can be treated with targeted drugs while lifestyle intervention is the only reasonable therapeutic approach for transplant patients with non-alcoholic steatosis or steatohepatitis.

  4. Immunosupression in liver transplant for hepatocellular carcinoma

    Full Text Available

    The hepatocellular carcinoma (HCC has turned into a frequent indication for liver transplant. The reports of different series indicate that it represents at least 12% of all liver transplants in Europe. But what kind of inmunosuppression is better in these patients is an unanswered question. Our intension with this review is to give basic information to define which would be the best immunosuppression alternative. There is enough information on the relationship between immunosuppression and cancer, as it is seen in states of primary immunodeficiency or infection with the Human Immunodeficiency virus (HIV. The immune system offers a state of permanent guard to avoid the arousal of neoplasic diseases in immunocompetent patients and from this point of view it has been seen that in immunosuppressed patients there is an association with this condition and the development of lymphoproliferative disorders, which can range from reversible diseases (polyclonal proliferation of B type lymphocytes to the development of a lymphoma and other types of tumors, like the ones observed in skin, genital region or oropharynx. Colon tumors and breast tumors have not been associated with immunosuppression. Immunosuppressive medication takes part in a different manner in the development of tumors, it has been said that steroids that are associated with some tumors, especially those regarding skin, paradoxically have a protective role in the development of lymph tissue tumors.

    It has been said about Azathioprine and Mycophenolate mofetil (MMF that its immunosuppressive effect is an antiproliferative type of immunosuppression, inhibiting the synthesis of purinic nucleotides, especially in lymphocytes. Azathioprine has been involved in the development of hepatic tumors, especially in the era previous

  5. Cardiac imaging for the assessment of patients being evaluated for kidney or liver transplantation. (United States)

    Parikh, Kalindi; Appis, Andrew; Doukky, Rami


    Cardiac risk assessment prior to kidney and liver transplantation is controversial. Given the paucity of available organs, selecting appropriate recipients with favorable short- and long-term cardiovascular risk profile is crucial. Using noninvasive cardiac imaging tools to guide cardiovascular risk assessment and management can also be challenging and controversial. In this article, we address the burden of coronary artery disease among kidney and liver transplant candidates and review the literature pertaining to the diagnostic accuracy and the prognostic value of noninvasive cardiac imaging techniques in this population.

Improved surgical and medical management has led to significant improvements in post-transplant survival rates with a 1 year and 5 year patient survival of 87% and 73%, respectively. A high mortality rate due to infections during the first post-transplant year persists. Invasive candidiasis is recognized as a significant problem associated with high morbidity and mortality. Recent surveillance data has helped to understand the changes in the epidemiology and the evolving trends in the use of antifungal agents for prophylaxis and treatment combined with the challenges of managing these invasive fungal infections, which has led the transplant community to explore the best management strategies. The emergence of resistant fungi and excess costs in managing these invasive fungal infections has added to the complexities of management. In this context, current perspectives in the management of Candida infections in liver transplant recipients will be reviewed. Keywords: Candida infections, management, liver transplant

    AIM: To describe cases of gut perforation after orthotopic liver transplantation.METHODS: Data were colleted from our center database and medical records. Six of 187 patients (3.2%)who underwent orthotopic liver transplantation from January to December 2005 developed gut perforation.All patients were male with an average age of 46 years.Modified piggyback liver transplantation was performed at the Organ Transplantation Center, First Affiliated Hospital, Sun Yat-Sen University.RESULTS: Previous operation, steroid therapy, and prolonged portal venous cross clamp time, poor nutritional status and iatrogenic injury were found to be its ecological factors. The patients with gut perforation were found to have fever, increased leukocytes, mild abdominal pain and tenderness. The median portal venous clamp time was 63 min (range 45-72 min),median cold ischaemia time was 11.3 h (range 7-15 h).Median intraoperative blood loss was 500 mL (range 100-1200 mL) and median operation time was 8.8 h (range 6-12 h). None of the six patients developed acute cellular rejection. White cell count was above 18 × 109/L in five patients (neutrophilic leukocytes were above 90%) and 1.5 × 109/L in one patient. Bacterial culture in drainage liquid revealed enterococci in five patients. Of the 6 patients undergoing orthotopic liver transplantation, 3 survived and 3 died after modified piggyback liver transplantation.CONCLUSION: Gut perforation occurs after orthotopic liver transplantation in adults. A careful and minimal dissection during OLT, longer retention of the stomach tube, and reducing the portal clamp time and steroid dose should be taken into consideration. If gut perforation is not prevented, then early diagnosis,preferably through detection of enterococci may ensure better survival.

    The aim of this study was to evaluate a software tool for non-invasive preoperative volumetric assessment of potential donors in living donated liver transplantation (LDLT). Biphasic helical CT was performed in 56 potential donors. Data sets were post-processed using a non-commercial software tool for segmentation, volumetric analysis and visualisation of liver segments. Semi-automatic definition of liver margins allowed the segmentation of parenchyma. Hepatic vessels were delineated using a region-growing algorithm with automatically determined thresholds. Volumes and shapes of liver segments were calculated automatically based on individual portal-venous branches. Results were visualised three-dimensionally and statistically compared with conventional volumetry and the intraoperative findings in 27 transplanted cases. Image processing was easy to perform within 23 min. Of the 56 potential donors, 27 were excluded from LDLT because of inappropriate liver parenchyma or vascular architecture. Two recipients were not transplanted due to poor clinical conditions. In the 27 transplanted cases, preoperatively visualised vessels were confirmed, and only one undetected accessory hepatic vein was revealed. Calculated graft volumes were 1110{+-}180 ml for right lobes, 820 ml for the left lobe and 270{+-}30 ml for segments II+III. The calculated volumes and intraoperatively measured graft volumes correlated significantly. No significant differences between the presented automatic volumetry and the conventional volumetry were observed. A novel image processing technique was evaluated which allows a semi-automatic volume calculation and 3D visualisation of the different liver segments. (orig.)

  10. Right Gastroepiploic Artery as an Alternative for Arterial Reconstruction in Living Donor Liver Transplantation

    Directory of Open Access Journals (Sweden)

    Klaus Steinbrück


    Full Text Available Background. An adequate blood flow is directly related to graft survival in living donor liver transplantation. However, in some cases, unfavorable conditions prevent the use of the hepatic artery for arterial reconstruction. Herein, we report a case in which the recipient right gastroepiploic artery was used as an option for arterial reconstruction in adult-to-adult living donor liver transplantation. Case Report. A 62-year-old woman, with cirrhosis due to hepatitis B associated with hepatocellular carcinoma, was submitted to living donor liver transplantation. During surgery, thrombosis of the hepatic artery with intimal dissection until the celiac trunk was observed, which precluded its use in arterial reconstruction. We decided to use the right gastroepiploic artery for arterial revascularization of the liver graft. Despite the discrepancy in size between donor hepatic artery and recipient right gastroepiploic artery, anastomosis was performed successfully. Conclusions. The use of the right gastroepiploic artery as an alternative for arterial revascularization of the liver graft in living donor liver transplantation should always be considered when the hepatic artery of the recipient cannot be used. For performing this type of procedure, familiarity with microsurgical techniques by the surgical team is necessary.

    Full Text Available HEHE is a rare neoplasm of vascular origin that occurs in the liver; UNOS reported a favorable outcome after liver transplantation in 110 patients with 1-year and 5-year survival of 80% and 64%. Case Report. A 40-year-old lady presented with a three-month history of right upper abdominal pain with nausea, vomiting, and significant loss of weight associated with scleral icterus and progressive abdominal distension. Examination revealed jaundice, hepatomegaly, and ascites. Serum bilirubin was 26.5 mg/dL and ALP was 552 CT. Abdomen and pelvis showed diffuse infiltrative neoplastic process of the liver with a mass effect and stretching of the hepatic and portal veins, in addition to bile duct dilatation. Viral hepatitis markers were negative and serum alpha fetoprotein was within reference range. Liver biopsy was consistent with HEHE, with positive endothelial markers (CD31, CD34, and factor VIII-related antigen. She underwent living related liver transplantation on June 2013 and was discharged after 20 days with normal liver enzymes. Four months later, she presented with diffuse disease recurrence. Liver biopsy confirmed disease recurrence; she received supportive treatment and unfortunately she died 2 weeks later. Conclusion. HEHE can have rapid and aggressive recurrence after liver transplantation.

    BACKGROUND: Hepatic artery (HA) reconstruction is one of the key steps for living donor liver transplantation (LDLT). The incidence of HA thrombosis has been reduced by the introduction of microsurgical techniques under a high resolution microscope or loupe. METHODS: We report our experience in 101 cases of HA reconstruction in LDLTs using the graft-artery-unclamp and posterior-wall-ifrst technique. The reconstructions were completed by either a plastic surgeon or a transplant surgeon. RESULTS: The rate of HA thrombosis was 2%(2/101). The risk factors for failed procedures appeared to be reduced by participation of the transplant surgeon compared with the plastic surgeon. For a graft with duplicate arteries, we considered no branches should be discarded even with a positive clamping test. CONCLUSIONS: HA reconstruction without clamping the graft artery is a feasible and simpliifed technique, which can be mastered by transplant surgeons with considerable microsurgical training.

  13. Orthotopic Liver Transplantation for Urea Cycle Enzyme Deficiency (United States)

    Todo, Satoru; Starzl, Thomas E.; Tzakis, Andreas; Benkov, Keith J.; Kalousek, Frantisek; Saheki, Takeyori; Tanikawa, Kyuichi; Fenton, Wayne A.


    Hyperammonemia, abnormalities in plasma amino acids and abnormalities of standard liver functions were corrected by orthotopic liver transplantation in a 14-day-old boy with carbamyl phosphate synthetase-I deficiency and in a 35-yr-old man with argininosuccinic acid synthetase deficiency. The first patient had high plasma glutamine levels and no measureable citrulline, whereas citrulline values were markedly increased in Patient 2. Enzyme analysis of the original livers showed undetectable activity of carbamyl phosphate synthetase-I in Patient 1 and arginosuccinic acid synthetase in Patient 2. Both patients were comatose before surgery. Intellectual recovery of patient 1 has been slightly retarded because of a brain abscess caused by Aspergillus infection after surgery. Both patients are well at 34 and 40 mo, respectively, after surgery. Our experience has shown that orthotopic liver transplantation corrects the life-threatening metabolic abnormalities caused by deficiencies in the urea cycle enzymes carbamyl phosphate synthetase-I and arginosuccinic acid synthetase. Seven other patients–six with ornithine transcarbamylase deficiency and another with carbamyl phosphate synthetase-I deficiency–are known to have been treated elsewhere with liver transplantation 1½ yr or longer ago. Four of these seven recipients also are well, with follow-ups of 1½ to 5 yr. Thus liver transplantation corrects the metabolic abnormalities of three of the six urea cycle enzyme deficiencies, and presumably would correct all. PMID:1544622

  14. The Origin of New-Onset Diabetes After Liver Transplantation: Liver, Islets, or Gut? (United States)

    Ling, Qi; Xu, Xiao; Wang, Baohong; Li, Lanjuan; Zheng, Shusen


    New-onset diabetes is a frequent complication after solid organ transplantation. Although a number of common factors are associated with the disease, including recipient age, body mass index, hepatitis C infection, and use of immunosuppressive drugs, new-onset diabetes after liver transplantation (NODALT) has the following unique aspects and thus needs to be considered its own entity. First, a liver graft becomes the patient's primary metabolic regulator after liver transplantation, but this would not be the case for kidney or other grafts. The metabolic states, as well as the genetics of the graft, play crucial roles in the development of NODALT. Second, dysfunction of the islets of Langerhans is common in cirrhotic patients and would be exacerbated by immunosuppressive agents, particularly calcineurin inhibitors. On the other hand, minimized immunosuppressive protocols have been widely advocated in liver transplantation because of liver tolerance (immune privilege). Third and last, through the "gut-liver axis," graft function is closely linked to gut microbiota, which is now considered an important metabolic organ and known to independently influence the host's metabolic homeostasis. Liver transplant recipients present with specific gut microbiota that may be prone to trigger metabolic disorders. In this review, we proposed 3 possible sites for the origin of NODALT, which are liver, islets, and gut, to help elucidate the underlying mechanism of NODALT.

  15. Cytomegalovirus infection after liver transplantation: Current concepts and challenges

    Institute of Scientific and Technical Information of China (English)

    Raymund Rabe Razonable


    Cytomegalovirus(CMV)is a common viral pathogen that influences the outcome of liver transplantation.In addition to the direct effects of CMV syndrome and tissue-invasive diseases,CMV is associated with an increased predisposition to acute and chronic allograft rejection,accelerated hepatitis C recurrence,and other opportunistic infections,as well as reduced overall patient and allograft survival.Risk factors for CMV disease are often interrelated,and include CMV D+/R-serostatus,acute rejection,female gender,age,use of high-dose mycophenolate mofetil and prednisone,and the overall state of immunity.In addition to the role of CHV-specific CD4+ and CD8+ T lymphocytes,there are data to suggest that functionality of the innate immune system contributes to CMV disease pathogenesis.In one study,liver transplant recipients with a specific polymorphism in innate immune molecules known as Toll-like receptors were more likely to develop higher Ievels of CMV replication and clinical disease.Because of the direct and indirect adverse effects of CMV disease,its prevention,whether through antiviral prophylaxis or preemptive therapy,is an essential component in improving the outcome of liver transplantation.In the majority of transplant centers,antiviral prophylaxis is the preferred strategy over preemptive therapy for the prevention of CMV disease in CMV-seronegative recipients of liver allografts from CMV-seropositive donors(D+/R-).However,the major drawback of antiviral prophylaxis is the occurrence of delayed-onset primary CMV disease.In several prospective and retrospective studies,the incidence of delayed-onset primary CMV disease ranged from 16% to 47% of CMV D+/R-liver transplant recipients.Current data suggests that delayed-onset CMV disease is associated with increased mortality after liver transplantation.Therefore,optimized strategies for prevention and novel drugs with unique modes of action are needed.Currently,a randomized controlled clinical trial is being

  17. Predicting short-term survival after liver transplantation on eight score systems: a national report from China Liver Transplant Registry. (United States)

    Ling, Qi; Dai, Haojiang; Zhuang, Runzhou; Shen, Tian; Wang, Weilin; Xu, Xiao; Zheng, Shusen


    To compare the performance of eight score systems (MELD, uMELD, MELD-Na. iMELD, UKELD, MELD-AS, CTP, and mCTP) in predicting the post-transplant mortality, we analyzed the data of 6,014 adult cirrhotic patients who underwent liver transplantation between January 2003 and December 2010 from the China Liver Transplant Registry database. In hepatitis B virus (HBV) group, MELD, uMELD and MELD-AS showed good predictive accuracies at 3-month mortality after liver transplantation; by comparison with other five models, MELD presented the best ability in predicting 3-month, 6-month and 1-year mortality, showing a significantly better predictive ability than UKELD and iMELD. In hepatitis C virus and Alcohol groups, the predictive ability did not differ significantly between MELD and other models. Patient survivals in different MELD categories were of statistically significant difference. Among patients with MELD score >35, a new prognostic model based on serum creatinine, need for hemodialysis and moderate ascites could identify the sickest one. In conclusion, MELD is superior to other score systems in predicting short-term post-transplant survival in patients with HBV-related liver disease. Among patients with MELD score >35, a new prognostic model can identify the sickest patients who should be excluded from waiting list to prevent wasteful transplantation.

  18. Neurological complications post-liver transplantation: impact of nutritional status. (United States)

    Bemeur, Chantal


    Nutritional status is significantly altered in patients with end-stage liver disease (cirrhosis). Malnutrition is a common complication of cirrhosis and is known to be associated with a greater risk of post-operative complications and mortality, especially following liver transplantation. Neurological complications occur frequently after transplant and the nature and extent of these complications may relate to nutritional deficits such as protein-calorie malnutrition as well as vitamin and micronutrient deficiencies. A consensus document from the International Society on Hepatic Encephalopathy and Nitrogen metabolism (ISHEN) has been established in order to address these concerns. Careful assessment of nutritional status followed by prompt treatment of nutritional deficits has the potential to impact on transplant outcome and, in particular, on post-transplant neurological disorders in patients with cirrhosis.

  19. Internal Hernia in a Liver Transplant Recipien: A Case Report

    Directory of Open Access Journals (Sweden)

    Hironori Hayashi


    Full Text Available Biliary complications have great importance for liver transplant recipients because of affecting long-term prognosis. In rare situations, an internal hernia of the Roux-en-Y loop cause graft injury. A 42-year-old woman with a history of living donor liver transplantation 6 years ago presented with prolonged graft injury during the past 6 months. She suddenly developed ileus of the small bowel with internal hernia through the defect of the mesentery around the Roux-en-Y limb of the hepaticojejunostomy. Emergent surgery was performed to reduce the hernia and volvulus; also the mesenteric rent was closed with interrupted suture of silk. Internal hernia of the small bowel after liver transplantation is rare but causes graft injury due to associated biliary complications and rapid deterioration of patient’s condition.

[Georgetown University Hospital, Department of Surgery, Division of Transplant Surgery, Washington, DC (United States)


    Cystic duct remnant mucocele is an extremely rare complication of liver transplantation in children. Surgical correction is usually required for cystic duct remnant mucocele when it causes biliary obstruction. We describe a 14-month-old liver transplant recipient who presented with biliary obstruction 1 month after orthotopic liver transplantation with an end-to-end choledochocholedocal biliary anastomosis for hepatoblastoma. US, CT and cholangiography findings were consistent with mucocele of the allograft cystic duct remnant. Surgery was not needed in our patient because the mucocele and biliary obstruction had resolved on repeat imaging most likely due to guidewire manipulation during cholangiography, resulting in opening of the cystic duct remnant orifice and drainage into the common duct.

    We reviewed the current status of liver transplantation in Latin America. We used data from the Latin American and Caribbean Transplant Society and national organizations and societies, as well as information obtained from local transplant leaders. Latin America has a population of 589 million (8.5% of world population) and more than 2,500 liver transplantations are performed yearly (17% of world activity), resulting in 4.4 liver transplants per million people (pmp) per year. The number of liver transplantations grows at 6% per year in the region, particularly in Brazil. The top liver transplant rates were found in Argentina (10.4 pmp), Brazil (8.4 pmp), and Uruguay (5.5 pmp). The state of liver transplantation in some countries rivals those in developed countries. Model for End-Stage Liver Disease-based allocation, split, domino, and living-donor adult and pediatric transplantations are now routinely performed with outcomes comparable to those in advanced economies. In contrast, liver transplantation is not performed in 35% of Latin American countries and lags adequate resources in many others. The lack of adequate financial coverage, education, and organization is still the main limiting factor in the development of liver transplantation in Latin America. The liver transplant community in the region should push health care leaders and authorities to comply with the Madrid and Istambul resolutions on organ donation and transplantation. It must pursue fiercely the development of registries to advance the science and quality control of liver transplant activities in Latin America.

    We present a case of progressive pulmonary calcification associated with prolonged respiratory insufficiency in a 2-year-old boy with a history of orthotopic liver transplantation. This case demonstrates the potentially progressive nature of pulmonary calcification and that it can present with respiratory insufficiency at a later period after transplantation than previously thought. We describe radiological findings and discuss established as well as plausible pathological mechanisms contributing to the development of calcifications in these patients. (orig.)

  7. Are liver transplant recipients protected against hepatitis A and B? (United States)

    Andersson, D; Castedal, M; Friman, V


    Liver transplant recipients are at an increased risk for liver failure when infected with hepatitis A virus (HAV) and hepatitis B virus (HBV). Therefore, it is important to vaccinate these individuals. The aim of the study was to evaluate how well liver transplanted patients in our unit were protected against HAV and HBV infection. Furthermore we investigated the vaccination rate and the antibody response to vaccination in these liver transplanted patients. Patients liver transplanted from January 2007 until August 2010 with a posttransplant check-up during the period March-November 2010 were included (n = 51). Information considering diagnose, date of transplantation, Child-Pugh score, and vaccination were collected from the patient records. Anti-HAV IgG and anti-HBs titers in serum samples were analyzed and protective levels were registered. Of the patients 45% were protected against hepatitis A infection and 29% against hepatitis B infection after transplantation. Only 26% were vaccinated according to a complete vaccination schedule and these patients had a vaccine response for HAV and HBV of 50% and 31%, respectively. An additional 31% received ≥ 1 doses of vaccine, but not a complete vaccination and the vaccine response was much lower among these patients, stressing the importance of completing the vaccination schedule. Even when patients were fully vaccinated, they did not respond to the same degree as healthy individuals. Patients seemed to be more likely to respond to a vaccination if they had a lower Child-Pugh score, suggesting that patients should be vaccinated as early as possible in the course of their liver disease.

    Szili, Balázs; Görög, Dénes; Gerlei, Zsuzsanna; Győri, Gabriella; Lakatos, Péter; Takács, István


    Glycogen storage disease Ib is a rare, inherited metabolic disorder caused by glucose-6-phosphatase translocase deficiency. Its main symptoms are hypoglycemia, hyperlipidemia, neutropenia, hepatomegaly, liver adenomas and short stature. The exact mechanism of short stature in this disease is unclear, the most feasible possibility is that it is caused by impairment of growth-hormone and insulin-like growth factor I axis. Here we report the case of a patient who showed typical symptoms of glycogen storage disease Ib since his infancy, his height being under 1 percentile since then. Later-developed hypothyroidism and hypogonadism have also contributed to his short stature. Hypothyroidism was treated but sexual steroid substitution was not started because of an increased risk of hepatic adenomas. Because he developed hepatic adenoma at the age of 23, he had to undergo orthotopic liver transplantation. At the time of the transplantation his height was 128cm. The transplantation was followed by rapid height growth; our patient's height reached 160.3cm 62months after transplantation. We observed that while his IGF-I level increased, his GH level remained unchanged. During the post-transplantation period we ensured adequate calcium and vitamin D supplementation, leaving hormonal substitution unchanged. According to our knowledge, this is the first report of a rapid height growth as big as 32cm, of an individual over the age of 20, not related to endocrine treatment but liver transplantation.

  11. Early Liver Transplantation for Neonatal-Onset Methylmalonic Acidemia. (United States)

    Spada, Marco; Calvo, Pier Luigi; Brunati, Andrea; Peruzzi, Licia; Dell'Olio, Dominic; Romagnoli, Renato; Porta, Francesco


    With conventional dietary treatment, the clinical course of methylmalonic acidemia due to cobalamin-unresponsive methylmalonyl-CoA mutase (MCM) deficiency is characterized by the persistent risk of recurrent life-threatening decompensation episodes with metabolic acidosis, hyperammonemia, and coma. Liver transplant has been proposed as an alternative treatment and anecdotally attempted in the last 2 decades with inconsistent results. Most criticisms of this approach have been directed at the continuing risk of neurologic and renal damage after transplant. Here, we report the perioperative and postoperative clinical and biochemical outcomes of 2 patients with severe MCM deficiency who underwent early liver transplant. In both cases, liver transplant allowed prevention of decompensation episodes, normalization of dietary protein intake, and a marked improvement of quality of life. No serious complications have been observed at 12 years' and 2 years' follow-up, respectively, except for mild kidney function impairment in the older patient. On the basis of our experience, we strongly suggest that liver transplant should be offered as a therapeutic option for children with cobalamin-unresponsive MCM deficiency at an early stage of the disease.

    Experiences in the blood flow measurement (/sup 133/Xe washing out) and function test (/sup 133/I-bromosulfophthalein, /sup 99m/Tc-IDA) in auxiliary liver transplantation in miniature swine are reported. Normal values for global blood flow (70 (35-144) ml/100 g x min) and the bromosulfophthalein half-time (6.5 +- 2.4 min) were defined preoperatively. Selective blood flow measurements were carried out invasively after transplantation. Only insufficient experience was obtained in scintiscanning of liver and biliary ducts because of graft insufficiency.

    Ashish V Choudhrie


    Full Text Available Amoebic liver abscess (ALA is by far the most common extraintestinal manifestation of invasive amoebiasis. The vast majority of these resolve with treatment; however, a small percentage of the treated ALAs are known to persist asymptomatically. Herein, we present a prospective renal allograft recipient with a residual liver abscess who had a successful renal transplant after treatment. In our opinion, persistence of a radiological finding of residual abscess in the absence of clinical disease does not appear to be a contraindication to renal transplantation.

  14. Current status and recent advances of liver transplantation from donation after cardiac death. (United States)

    Perera, M Thamara Pr; Bramhall, Simon R


    The last decade saw increased organ donation activity from donors after cardiac death (DCD). This contributed to a significant proportion of transplant activity. Despite certain drawbacks, liver transplantation from DCD donors continues to supplement the donor pool on the backdrop of a severe organ shortage. Understanding the pathophysiology has provided the basis for modulation of DCD organs that has been proven to be effective outside liver transplantation but remains experimental in liver transplantation models. Research continues on how best to further increase the utility of DCD grafts. Most of the work has been carried out exploring the use of organ preservation using machine assisted perfusion. Both ex-situ and in-situ organ perfusion systems are tested in the liver transplantation setting with promising results. Additional techniques involved pharmacological manipulation of the donor, graft and the recipient. Ethical barriers and end-of-life care pathways are obstacles to widespread clinical application of some of the recent advances to practice. It is likely that some of the DCD offers are in fact probably "prematurely" offered without ideal donor management or even prior to brain death being established. The absolute benefits of DCD exist only if this form of donation supplements the existing deceased donor pool; hence, it is worthwhile revisiting organ donation process enabling us to identify counter remedial measures.

    Objective: The aim of this study was to determine the effectiveness and safety of percutaneous laser ablation for the treatment of cirrhotic patients with hepatocellular carcinoma awaiting liver transplantation. Materials and methods: The data of 9 male cirrhotic patients (mean age 50 years, range 45-60 years) with 12 biopsy proven nodules of hepatocellular carcinoma (mean diameter 2.0 cm, range 1.0-3.0 cm) treated by laser ablation before liver transplantation between June 2000 and January 2006 were retrospectively reviewed. Laser ablation was carried out by inserting 300 nm optical fibers through 21-Gauge needles (from two to four) positioned under ultrasound guidance into the target lesions. A continuous wave Neodymium:Yttrium Aluminium Garnet laser was used. Transarterial chemoembolization prior to liver transplantation was performed in two incompletely ablated tumors. Results: No procedure-related major complications were recorded. During the waiting time to liver transplantation local tumor progression after ablation occurred in 3 nodules (25%). At histological examination of the explanted livers complete necrosis was found in 8 nodules (66.7%, all treated exclusively with laser ablation), partial necrosis >50% in 3 nodules (25%), and partial necrosis <50% in 1 nodule. Conclusion: In patients with cirrhotic livers awaiting liver transplantation, percutaneous laser ablation is safe and effective for the management of small hepatocellular carcinoma.

  16. Kidney and liver transplantation in children with fibrocystic liver-kidney disease: data from the US Scientific Registry of Transplant Recipients: 1990-2010. (United States)

    Wen, Jessica W; Furth, Susan L; Ruebner, Rebecca L


    The natural history and survival of children with fibrocystic liver-kidney disease undergoing solid organ transplantation have infrequently been described. We report outcomes in a cohort of US children with fibrocystic liver-kidney disease receiving solid organ transplants over 20 yr. Retrospective cohort study of pediatric transplant recipients with diagnoses of fibrocystic liver-kidney disease from 1/1990 to 3/2010, using data from the SRTR. Subjects were categorized by the first transplanted organ: LT, KT, or SLK. Primary outcomes were death, re-transplant, transplant of the alternate organ, or initiation of dialysis. Seven hundred and sixteen subjects were transplanted in this period. Median age at first transplant was 9.7 yr. Of the LT, 14 (19%) required a second liver transplant at median of 0.2 yr, and five (7%) required kidney transplant or dialysis at a median of 9.0 yr. Of the KT, 188 (31%) required a second kidney transplant or dialysis at a median of 5.9 yr. Twenty-nine (5%) subsequently received liver transplant at a median of 6.0 yr. Among patients in this registry, far more children underwent kidney than liver transplants. The risk of subsequently needing transplantation of an alternate organ was low.

  17. Acute Kidney Disease After Liver and Heart Transplantation. (United States)

    Rossi, Ana P; Vella, John P


    After transplantation of nonrenal solid organs, an acute decline in kidney function develops in the majority of patients. In addition, a significant number of nonrenal solid organ transplant recipients develop chronic kidney disease, and some develop end-stage renal disease, requiring renal replacement therapy. The incidence varies depending on the transplanted organ. Acute kidney injury after nonrenal solid organ transplantation is associated with prolonged length of stay, cost, increased risk of death, de novo chronic kidney disease, and end-stage renal disease. This overview focuses on the risk factors for posttransplant acute kidney injury after liver and heart transplantation, integrating discussion of proteinuria and chronic kidney disease with emphasis on pathogenesis, histopathology, and management including the use of mechanistic target of rapamycin inhibition and costimulatory blockade.

    BACKGROUND: Glycogen storage disease (GSD) is an inherited metabolic disorder in which the concentration and/or structure of glycogen in tissues is abnormal. Essentially, abnormalities in all known enzymes involved in the synthesis or degradation of glycogen and glucose have been found to cause some type of GSD. Liver and muscle have abundant quantities of glycogen and are the most common and seriously affected tissues. This study was to assess reduced-size liver transplantation for the treatment of GSD. METHODS: The clinical data from one case of GSD typeⅠ with hepatic adenoma was retrospectively analyzed. The clinical manifestations were hepatomegaly, delayed puberty, growth retardation, sexual immaturity, hypoglycemia, and lactic acidosis, which made the young female patient eligible for reduced-size liver transplantation. RESULTS: The patient recovered uneventfully with satisfactory outcome, including 12 cm growth in height and 5 kg increase in weight during 16 months after successful reduced-size liver transplantation. She has been living a normal life for 4 years so far. CONCLUSIONS: Reduced-size liver transplantation is an effective treatment for GSD with hepatomegaly and hepatic adenoma. Delayed puberty, growth retardation, hypoglycemia and lactic acidosis can be cured by surgery.

    Objective: To set up a simple and reliable rat model of combined liver-kidney transplantation. Methods: SD rats served as both donors and recipients. 4℃ sodium lactate Ringer's was infused from portal veins to donated livers,and from abdominal aorta to donated kidneys, respectively. Anastomosis of the portal vein and the inferior vena cava (IVC) inferior to the right kidney between the graft and the recipient was performed by a double cuff method, then the superior hepatic vena cava with suture. A patch of donated renal artery was anastomosed to the recipient abdominal aorta. The urethra and bile duct were reconstructed with a simple inside bracket. Results: Among 65 cases of combined liver-kidney transplantation, the success rate in the late 40 cases was 77.5%. The function of the grafted liver and kidney remained normal. Conclusion: This rat model of combined liver-kidney transplantation can be established in common laboratory conditions with high success rate and meet the needs of renal transplantation experiment.

    There are many risk factors for postoperative acute kidney injury in liver transplantation. The aim of this study is to investigate the risk factors for postoperative acute kidney injury in living donor liver transplantation recipients. 220 living donor liver transplantation recipients were retrospectively evaluated in the study. According to the Kidney Disease Improving Global Outcomes Guidelines, acute kidney injury in postoperative day 7 was investigated for all patients. The patient's demographic data, preoperative and intraoperative parameters, and outcomes were recorded. Acute kidney injury was found in 27 (12.3%) recipients. In recipients with acute kidney injury, female population, model for end-stage liver disease score, norepinephrine requirement, duration of mean arterial pressure less than 60 mmHg, the usage of gelatin and erythrocyte suspension and blood loss were significantly higher than recipients with nonacute kidney injury (for all p5 mL kg-1 and duration of MAP less than 60 mmHg ≥5.5 minutes respectively (for all p<0.05). In living donor liver transplantation recipients, serum tacrolimus levels, intraoperative blood loss, hypotension period and the usage of gelatin may be risk factors for acute kidney injury in the early postoperative period.

  2. What is the real gain after liver transplantation? (United States)

    Neuberger, James


    1. For most liver allograft recipients, both the quality and length of life are greatly improved after transplantation. However, neither the quality of life nor the length of life in the survivors returns to that seen in age-matched and sex-matched normal subjects. 2. The gain in survival after transplantation can be estimated by a comparison of the actual outcome after transplantation and the predicted survival in the absence of transplantation. 3. The reduction in graft and patient survival, in comparison with a normal age-matched and sex-matched population, is determined by several factors: short-term survival is affected by the patient's condition pre-transplant and the quality of the graft, and for longer term survival, recurrent disease accounts for most of the differences seen between different indications. Some of the causes of premature death (such as infection, de novo malignancy, and cardiovascular and cerebrovascular disease) that are increased in the liver allograft recipient may be reduced by improved management with more aggressive surveillance and treatment. 4. The aims of selection and allocation vary in different health care systems: transparency, objectivity, equity of access, justice, mortality awaiting transplantation, utility, and transplant benefit are all important but often competing demands. Understanding the associated increase in survival will allow for a rational approach to this complex area. (c) 2009 AASLD.

  4. Reconstruction of the Outflow Tract in Cross-Auxiliary Double-Domino Donor Liver Transplantation. (United States)

    Qu, W; Zhu, Z-J; Wei, L; Sun, L-Y; Liu, Y; Zeng, Z-G


    Auxiliary liver transplantation is accepted as an effective manner to expand the liver donor pool. A difficult surgical technical challenge of the procedure is hepatic vein reconstruction of the graft. To resolve this problem, complex techniques are used to perform an innovative outflow tract reconstruction in the world's first cross-auxiliary double-domino donor liver transplantation with two whole liver grafts. The inferior vena cava-sparing hepatectomy technique was applied at harvest in the two domino liver donors. For each donor, the three major hepatic veins (right, middle, and left) were joined together to create one single orifice, but there was no sufficient tissue to perform a direct anastomosis. The hepatic vein was reconstructed with the use of a longitudinally opened iliac vein graft from a cadaveric donor to prolong the outflow tract for the piggyback suturing. This new technique might provide an innovative surgical approach for reconstructing the complex outflow tract of domino transplantation. Copyright © 2016 Elsevier Inc. All rights reserved.

  5. Contemporary anesthesia management for liver transplantation: a comparison of American and European methods. (United States)

    Bezinover, Dmitri; Kadry, Zakiyah; Janicki, Piotr


    This review article compares the organization of liver transplantation programs, anesthesia management and postoperative care in the United States and Europe. Liver transplantation is a definitive treatment for end-stage liver disease. The procedure is extremely complex and requires excellent surgical technique and experienced anesthesiologists who are able to provide precise management. Liver transplantation programs, which first started in the United States and a few years later in Europe, have quickly been able to achieve remarkable results. In the United States one organization, the United Network for Organ Sharing (UNOS) is responsible for the allocation of organs and data collection; in Europe there are various organizations with different levels of cooperation. The major difference between anesthesia management in the United States and Europe is the number of medications available for coagulation improvement. Substances such as prothrombin complex concentrate, fibrinogen, and antithrombin III allow for a greater flexibility in European anesthesia management. Thromboelastography, which is routinely used in the United States for overseeing coagulation, is now increasingly being used in Europe, and seems to be highly effective in providing precise information about coagulation. The overall ICU stay in Europe is longer than in the United States, and services such as maintenance of critical care, immunosuppression and nutrition are not separated in Europe. Despite these differences in liver transplantation programs, overall one-year patient survival rate is similar in the United States and in Europe, exceeding 85% in both.

  6. Occupational therapy services to enable liver patients to thrive following transplantation. (United States)

    Scott, Patricia J


    ABSTRACT Transplantation is the only viable treatment for end-stage liver failure. With advances in biomedicine and surgical technique, survival rates have improved and current research is beginning to focus on patient-related outcomes such as of quality of life (QOL) and life satisfaction. However, attention to the rehabilitation needs of those patients whose lives are saved, is lagging. Pretransplantation, there are serious strains to role function and limitations to mental and physical capacity. Following transplantation, the ability to perform once easy familiar tasks is difficult for a prolonged recovery period. Within a year many people do well, others do not. Little has been done for this latter group. The purpose of this article is to systematically describe the contributions occupational therapy can make to the people struggling with the challenges faced during the transplantation process. The first part presents a framework for understanding the impact of end-stage liver disease, then the transplant, and the subsequent recovery through the combination of two frameworks: the International Classification of Functioning Disability and Health (ICF) and the Model of Human Occupation. The second part of this article will present the implications for occupational therapists throughout seven stages: (1) decline in health, (2) organ failure, (3) referral for transplantation, (4) the waiting period, (5) the transplant surgery, (6) recovery, and (7) return of health. Attention to the needs of transplant recipients who lack the adaptive skills to resume productive lifestyles has the capacity to improve participation outcomes for this population.

    Sutariya, Vaibhav K; Tank, Anad H; Modi, Pranjal R


    Wilson's disease (WD) is an inherited autosomal recessive disorder characterized by copper accumulation and toxicity, affecting mainly the liver and brain. Orthotopic liver transplantation (OLT) is the definitive therapy for patients with WD. Acute fulminant hepatic failure and decompensated cirrhosis are well-established indications for OLT. Patients with severe neurologic impairment can also be benefited by OLT. Here, we present a patient who underwent OLT for isolated neurological WD.

    Extraction and preservation are of special interest in any liver transplant program. The viability and correct early function of the graft are determinant factors of the success or failure of the transplant. Application of a restrictive criterion in the acceptance of donor livers has allowed us to achieve an optimal viability (96.7%) in our first 60 cases of liver transplant.

    Liver transplant recipients frequently suffer gastrointestinal (GI) complications but their prevalence and their influence on quality of life remain unknown. The objective of this study was to asses the prevalence, impact on quality of life, and management of GI complications in liver transplant recipients. This was an epidemiologic, cross-sectional, multicenter study. Four hundred seventeen liver recipients were recruited in 14 centers. A questionnaire was filled for every patient. The median age of the patients was 55 years. The median time since transplantation was 4.1 +/- 4 years. Whereas 19.2% presented some GI disease before transplantation, 49.4% showed this type of complication after transplantation. Diarrhea was the most prevalent GI complication, and anorexia was the GI disorder that affected patients daily activities the most frequently. GI complications were more frequent among female patients, subjects with pretransplantation hiatal hernia, and those readmitted after transplantation. Of the patients with GI complications, 70.9% received pharmacological treatment (89.7% with gastric protectors). Immunosuppressive therapy was also modified because of GI complications. Immunosuppressive drug dose was reduced in 18.1%, transiently stopped in 3.4%, and definitively stopped in 3.4% of cases. The drug most frequently changed was mycophenolate mofetil: dose reduction, 23.6%; transient withdrawal, 5.7%; and definitive withdrawal, 6.6%. The prevalence of GI complications in the liver transplant population was approximately 50%. GI complications showed a significant impact on the quality of life of the patients. They were related to female gender, to pretransplantation GI pathology, and posttransplantation hospital admission. These complications were frequently managed with pharmacological therapy or with changes in immunosuppressive therapy.

  10. Physician predictions of graft survival following liver transplantation (United States)

    Feurer, Irene D.; Austin, Mary T.; Porayko, Michael K.; Wright, J. Kelly; Lorenzi, Nancy M.; Pinson, C. Wright; Aronsky, Dominik


    Introduction. Due to the scarcity of cadaveric livers, clinical judgment must be used to avoid futile transplants. However, the accuracy of human judgment for predicting outcomes following liver transplantation is unknown. The study aim was to assess expert clinicians’ ability to predict graft survival and to compare their performance to published survival models. Materials and methods. Pre-transplant case summaries were prepared based on 16 actual, randomly selected liver transplants. Clinicians specializing in the care of liver transplant patients were invited to assess the likelihood of 90-day graft survival for each case using (1) a 4-point Likert scale ranging from poor to excellent, and (2) a visual analog scale denoting the probability of survival. Four published models were also used to predict survival for the 16 cases. Results. Completed instruments were received from 50 clinicians. Prognostic estimates on the two scales were highly correlated (median r=0.88). Individual clinicians’ predictive ability was 0.61±0.13, by area under the receiver operating characteristic curve. The performance of published models was MELD 0.59, Desai 0.66, Ghobrial 0.61, and Thuluvath 0.45. For three cases, clinicians consistently overestimated the probability of survival (87±10%, 89±9%, 86±9%); these patients had early graft failures caused by postoperative complications. Discussion. Clinicians varied in their ability to predict survival for a set of pre-transplant scenarios, but performed similarly to published models. When clinicians overestimated the chance of transplant success, either sepsis or hepatic artery thrombosis was involved; such events may be hard to predict before surgery. PMID:18345303

    Introduction: Patients with advanced liver disease, especially chronic cholestasis, often have osteopenia, which worsens early after orthotopic liver transplantation (OLT) before starting to recover. The changes in bone metabolism leading to this rapid loss of bone after OLT, and to its recovery,

    Besides orthotopic liver transplantation (OLT) there is no long-term and effective replacement therapy for severe liver failure. Artificial extracorporeal liver supply devices are able to reduce blood toxin levels, but do not replace any synthetic function of the liver. Molecular adsorbent recirculating system (MARS) is one of the methods that can be used to treat fulminant acute liver failure (ALF) or acute on chronic liver failure (AoCLF). The primary non-function (PNF) of the newly transplanted liver manifests in the clinical settings exactly like acute liver failure. MARS treatment can reduce the severity of complications by eliminating blood toxins, so that it can help hepatic encephalopathy (HE), hepatorenal syndrome (HRS), and the high rate mortality of cerebral herniation. This might serve as a bridging therapy before orthotopic liver retransplantation (reOLT). Three patients after a first liver transplantation became candidate for urgent MARS treatment as a bridging solution prior to reOLT in our center. Authors report these three cases, fo-cusing on indications, MARS sessions, clinical courses, and final outcomes. PMID:24265893

  13. Succinct guide to liver transplantation for medical students

    Directory of Open Access Journals (Sweden)

    Cheng-Maw Ho


    Full Text Available Literature on liver transplantation for use in medical education is limited and as yet unsatisfactory. The aim of this article is to help medical students gain enough insight into the reality of being a liver transplant recipient. This is crucial so in the future they can feel confident in approaching these patients with adequate knowledge and confidence. The knowledge-tree based learning core topics are designed for a 2-h class including indication/contraindication in the real-world setting, model for end stage liver disease scoring and organ allocation policy, liver transplantation for hepatic malignancy, transplantation surgery, immunosuppression strategy in practical consideration, and management of viral hepatitis. The rationales of each topic are discussed comprehensively for better understanding by medical students. Recipient candidates may have reversible contraindications that halt the surgery temporarily and therefore, it warrants re-evaluation before transplant. Organ allocation policy is primarily based on disease severity instead of waiting time. Transplant surgery usually involves resection of the whole liver, in situ implantation with reconstruction of the hepatic vein, the portal vein, the hepatic artery and the biliary duct in sequence. The primary goal of artificial immunosuppression is to prevent graft rejection, and the secondary one is to reduce its complication or side effects. Life-long oral nucleoside/nucleotide analogues against hepatitis virus B is needed while short course of direct acting agents against hepatitis viral C is enough to eradicate the virus. Basic understanding of the underlying rationales will help students prepare for advanced learning and cope with the recipients confidently in the future.

  14. Liver Transplantation and Cirrhotomimetic Hepatocellular Carcinoma: Classification and Outcomes (United States)

    Background & Aims Liver transplantation has become the standard of care treatment for hepatocellular carcinoma (HCC) that falls within size and numeric criteria in cirrhotic patients. Cirrhotomimetic (CMM) hepatocellular carcinoma is an uncommon growth pattern that infiltrates cirrhotic parenchyma, can become extensive in size, and can evade detection via radiologic studies. Liver transplant outcomes for this type of HCC is not well reported but generally considered to be poor. We wished to better describe this variant of HCC in explanted livers, derive a classification system for this tumor type, and assess the outcomes of liver transplantation for this tumor variant. Methods Upon retrospective analysis of all patients transplanted at a single center for HCC in 1996–2009 (358 patients) a series of 26 patients exhibiting CMM growth pattern were identified. We developed a classification system for this tumor growth pattern variant and determined patient and tumor-specific outcomes. Results We derived a classification schema of CMM HCC based upon tumor extent and cellular histopathology with clear cell pathology being associated with favorable outcome. We note a 100% 3-year and 58.3% 5-year recurrence free survival after transplant in those with tumor confined to one lobe who have clear cell pathology versus 16.2% 3- and 5-year recurrence free survival in those who do not meet these criteria. Conclusion Cirrhotomimetic HCC features are noted in 7% of patients transplanted for HCC in our center with favorable outcomes inpatients with clear cell histology and growth involving less than 50% of the liver.

  15. Proteomic analysis of tyrosine phosphorylation during human liver transplantation

    Directory of Open Access Journals (Sweden)

    Boutros Tarek


    Full Text Available Abstract Background Ischemia-reperfusion (I/R causes a dramatic reprogramming of cell metabolism during liver transplantation and can be linked to an alteration of the phosphorylation level of several cellular proteins. Over the past two decades, it became clear that tyrosine phosphorylation plays a pivotal role in a variety of important signalling pathways and was linked to a wide spectrum of diseases. Functional profiling of the tyrosine phosphoproteome during liver transplantation is therefore of great biological significance and is likely to lead to the identification of novel targets for drug discovery and provide a basis for novel therapeutic strategies. Results Using liver biopsies collected during the early phases of organ procurement and transplantation, we aimed at characterizing the global patterns of tyrosine phosphorylation during hepatic I/R. A proteomic approach, based on the purification of tyrosine phosphorylated proteins followed by their identification using mass spectrometry, allowed us to identify Nck-1, a SH2/SH3 adaptor, as a potential regulator of I/R injury. Using immunoblot, cell fractionation and immunohistochemistry, we demonstrate that Nck-1 phosphorylation, expression and localization were affected in liver tissue upon I/R. In addition, mass spectrometry identification of Nck-1 binding partners during the course of the transplantation also suggested a dynamic interaction between Nck-1 and actin during I/R. Conclusion Taken together, our data suggest that Nck-1 may play a role in I/R-induced actin reorganization, which was previously reported to be detrimental for the hepatocytes of the transplanted graft. Nck-1 could therefore represent a target of choice for the design of new organ preservation strategies, which could consequently help to reduce post-reperfusion liver damages and improve transplantation outcomes.

  16. Liver transplantation for nonalcoholic fatty liver disease: new challenges and new opportunities. (United States)

    Shaker, Mina; Tabbaa, Adam; Albeldawi, Mazen; Alkhouri, Naim


    Nonalcoholic fatty liver disease (NAFLD) is becoming rapidly one of the most common indications for orthotopic liver transplantation in the world. Development of graft steatosis is a significant problem during the post-transplant course, which may happen as a recurrence of pre-existing disease or de novo NAFLD. There are different risk factors that might play a role in development of graft steatosis including post-transplant metabolic syndrome, immune-suppressive medications, genetics and others. There are few studies that assessed the effects of NAFLD on graft and patient survival; most of them were limited by the duration of follow up or by the number of patients. With this review article we will try to shed light on post-liver transplantation NAFLD, significance of the disease, how it develops, risk factors, clinical course and treatment options.

  18. Evaluation of 100 patients for living donor liver transplantation. (United States)

    Trotter, J F; Wachs, M; Trouillot, T; Steinberg, T; Bak, T; Everson, G T; Kam, I


    The initial success of living donor liver transplantation (LDLT) in the United States has resulted in a growing interest in this procedure. The impact of LDLT on liver transplantation will depend in part on the proportion of patients considered medically suitable for LDLT and the identification of suitable donors. We report the outcome of our evaluation of the first 100 potential transplant recipients for LDLT at the University of Colorado Health Sciences Center (Denver, CO). All patients considered for LDLT had first been approved for conventional liver transplantation by the Liver Transplant Selection Committee and met the listing criteria of United Network for Organ Sharing status 1, 2A, or 2B. Once listed, those patients deemed suitable for LDLT were given the option to consider LDLT and approach potential donors. Donors were evaluated with a preliminary screening questionnaire, followed by formal evaluation. Of the 100 potential transplant recipients evaluated, 51 were initially rejected based on recipient characteristics that included imminent cadaveric transplantation (8 patients), refusal of evaluation (4 patients), lack of financial approval (6 patients), and medical, psychosocial, or surgical problems (33 patients). Of the remaining 49 patients, considered ideal candidates for LDLT, 24 patients were unable to identify a suitable donor for evaluation. Twenty-six donors were evaluated for the remaining 25 potential transplant recipients. Eleven donors were rejected: 9 donors for medical reasons and 2 donors who refused donation after being medically approved. The remaining 15 donor-recipient pairs underwent LDLT. Using our criteria for the selection of recipients and donors for LDLT gave the following results: (1) 51 of 100 potential transplant recipients (51%) were rejected for recipient issues, (2) only 15 of the remaining 49 potential transplant recipients (30%) were able to identify an acceptable donor, and (3) 15 of 100 potential living donor

    Full Text Available Hepatitis B virus (HBV-related liver disease is a common indication for liver transplantation (LT in Asian countries.1 When left untreated, the overall five-year survival rate in HBV-related cirrhosis is 71%, which in cases of decompensated cirrhosis decreases to 14%.2 In the 1980s, hepatitis B-related acute liver failure and chronic liver disease (CLD were considered contraindications for LT because of almost universal graft reinfection and high rates of graft and recipient failure (>50%.3-4 These patients had severe and rapidly progressive liver disease with a two-year graft and patient survival of 50% compared to 80% in those transplanted for non-HBV-related CLD.5 As a result, there were fewer LT for HBV liver disease for several years.6 However, with the introduction of nucleoside and nucleotide analogues and the use of intra and post- operative hepatitis B immunoglobulin (HBIG, there was renewed interest in the application of LT in these patients. There was a significant decrease in post-operative HBV recurrence rates.7-9 The current overall survival of patients transplanted for HBV-related cirrhosis has improved to 85% at one year, and 75% at five years.7,10-12 The present review highlights issues pertaining to HBV reinfection and de novo infection in LT recipients with recommendations for its management.

  1. Pre-Liver Transplant: Tips Versus Distal Splenorenal Shunt

    Directory of Open Access Journals (Sweden)

    Thomas W. Faust


    Full Text Available Recurrent variceal bleeding in liver transplant candidates with end-stage liver disease can complicate or even prohibit a subsequent transplant procedure (OLT. Endoscopic sclero-therapy and medical therapy are considered as first-line management with surgical shunts reserved for refractory situations. Surgical shunts can be associated with a high mortality in this population and may complicate subsequent OLT. The transjugular intrahepatic portosystemic shunt (TIPS has been recommended in these patients as a bridge to OLT. This is a new modality that has not been compared with previously established therapies such as the distal splenorenal shunt (DSRS. In this study we report our experience with 35 liver transplant recipients who had a previous TIPS (18 patients or DSRS (17 patients for variceal bleeding. The TIPS group had a significantly larger proportion of critically ill and Child-Pugh C patients. Mean operating time was more prolonged in the DSRS group (P=0.014 but transfusion requirements were similar. Intraoperative portal vein blood flow measurements averaged 2132±725 ml/min in the TIPS group compared with 1120±351ml/min in the DSRS group (P<0.001. Arterial flows were similar. Mean ICU and hospital stays were similar. There were 3 hospital mortalities in the DSRS group and none in the TIPS group (P=0.1. We conclude that TIPS is a valuable tool in the management of recurrent variceal bleeding prior to liver transplantation. Intra0Perative hemodynamic measurements suggest a theoretical advantage with TIPS. In a group of patients with advanced liver disease we report an outcome that is similar to patients treated with DSRS prior to liver transplantation. The role of TIPS in the treatment of nontransplant candidates remains to be clarified.

  2. Metabolic syndrome after liver transplantation: Preventable illness or common consequence?

    Institute of Scientific and Technical Information of China (English)

    Eric R Kallwitz


    The metabolic syndrome is common after liver transplant being present in approximately half of recipients.It has been associated with adverse outcomes such as progression of hepatitis C and major vascular events.As the United States population ages and the rate of obesity increases,prevention of the metabolic syndrome in the post-transplant population deserves special consideration.Currently,the metabolic syndrome after transplant appears at least two times more common than observed rates in the general population.Specific guidelines for patients after transplant does not exist,therefore prevention rests upon knowledge of risk factors and the presence of modifiable elements.The current article will focus on risk factors for the development of the metabolic syndrome after transplant,will highlight potentially modifiable factors and propose potential areas for intervention.As in the non-transplant population,behavioral choices might have a major role.Opportunities exist in this regard for health prevention studies incorporating lifestyle changes.Other factors such as the need for immunosuppression,and the changing characteristics of wait listed patients are not modifiable,but are important to know in order to identifypersons at higher risk.Although immunosuppression after transplant is unavoidable,the contribution of different agents to the development of components of the metabolic syndrome is also discussed.Ultimately,an increased risk of the metabolic syndrome after transplant is likely unavoidable,however,there are many opportunities to reduce the prevalence.

    To define the changes in liver and spleen volumes in the early postoperative period after partial liver donation for living-donor liver transplantation (LDLT) and to determine factors that influence liver and spleen volume changes. 27 donors who underwent partial hepatectomy for LDLT were included in this study. The rates of liver and spleen volume change, measured with CT volumetry, were correlated with several factors. The analyzed factors included the indocyanine green (ICG) retention rate at 15 minutes after ICG administration, preoperative platelet count, preoperative liver and splenic volumes, resected liver volume, resected-to-whole liver volume ratio (LV{sub R}/LV{sub W}), resected liver volume to the sum of whole liver and spleen volume ratio [LV{sub R}/(LV{sub W} + SV{sub 0})], and pre and post hepatectomy portal venous pressures. In all hepatectomy donors, the volumes of the remnant liver and spleen were increased (increased rates, 59.5 ± 50.5%, 47.9 ± 22.6%). The increment rate of the remnant liver volume revealed a positive correlation with LV{sub R}/LV{sub W} (r = 0.759, p < 0.01). The other analyzed factors showed no correlation with changes in liver and spleen volumes. The spleen and remnant liver volumes were increased at CT volumetry performed 2 weeks after partial liver donation. Among the various analyzed factors, LV{sub R}/LV{sub W} influences the increment rate of the remnant liver volume.

    The liver is an essential player in the pathway of coagulation in both primary and secondary haemostasis.Only von Willebrand factor is not synthetised by the liver, thus liver failure is associated with impairment of coagulation. However, recently it has been shown that the delicate balance between pro and antithrombotic factors synthetised by the liver might be reset to a lower level in patients with chronic liver disease. Therefore,these patients might not be really anticoagulated in stable condition and bleeding may be caused only when additional factors, such as infections, supervene. Portal hypertension plays an important role in coagulopathy in liver disease, reducing the number of circulating platelets, but platelet function and secretion of thrombopoietin have been also shown to be impaired in patients with liver disease. Vitamin K deficiency may coexist, so that abnormal clotting factors are produced due to lack of gamma carboxylation. Moreover during liver failure, there is a reduced capacity to clear activated haemostatic proteins and protein inhibitor complexes from the circulation. Usually therapy for coagulation disorders in liver disease is needed only during bleeding or before invasive procedures. When end stage liver disease occurs, liver transplantation is the only treatment available, which can restore normal haemostasis, and correct genetic clotting defects, such as haemophilia or factor V Leiden mutation. During liver transplantation haemorrage may occur due to the pre-existing hypocoagulable state, the collateral circulation caused by portal hypertension and increased fibrinolysis which occurs during this surgery.

  5. Managing hepatitis C in liver transplant patients with recurrent infection

    Full Text Available Tim Zimmermann1, Gerd Otto2, Marcus Schuchmann11Department of Internal Medicine, 2Transplantation Surgery, University of Mainz, GermanyAbstract: Hepatitis C virus (HCV reinfection after liver transplantation (LT and recurrent hepatitis C often lead to recurrent cirrhosis (RC. RC is one of the most frequent complications resulting in organ failure and early death after LT in HCV-positive patients with reported 5-year rates from 20% to 40%. As HCV-cirrhosis is one of the leading indications for LT, the therapeutic management is a central issue. To date, the best available therapy is a combination of pegylated interferon + ribavirin in patients with established recurrent hepatitis C proven by liver biopsy. Although increasing experience in using interferon therapy after LT has suggested better response rates, treatment is limited by a poor tolerability and high rates of severe side effects, necessitating lower doses or withdrawal of therapy. The extent to which dose reductions and the concomitant administration of growth factors affect virological response or prevent complications is still to be determined. Prospective clinical trials are mandatory to identify the best time point and schedule of antiviral treatment in transplant patients. Currently, therapeutic options need to be discussed for each individual patient. Therefore therapy should be carried out only in transplant centers with experience in managing hepatitis C after LT.Keywords: hepatitis C, liver transplantation, recurrent infection, treatment

    Background Hepatopulmonary syndrome is formed by a triad of liver disease, intrapulmonary vascular dilatation and changes in blood gases. This condition is present in 4-32% of patients with cirrhosis. Aim To analyze the blood gas changes data of patients in liver-transplant waiting list. Method Clinical data of 279 patients in liver transplantation waiting list in May 2013 were studied. Overall patient was analyzed by the demographic aspects, laboratorial and image findings on exams that determine lung disease (hypoxemia) in these cirrhotic patients. The mean values and standard deviations were used to examine normally distributed variables. Results There was a high prevalence of male patients (68%); the mean age was 51(±5,89) years, and the predominant reason for listing was hepatitis C cirrhosis. The MELD score mean was 16±5,89, without prioritization or special situation. The most common blood type was O in 129 cases (46%) and the mean of body max index was 25,94±4,58. Regarding arterial blood gas tests was observed 214 patients with PaO2 transplant. Due to the high severity and morbidity, is suggested better monitoring and therapeutic support to hypoxemic patients on liver transplant waiting list. PMID:24676301

  11. Effects of Kupffer cell inactivation on graft survival and liver regeneration after partial liver transplantation in rats

    Hang-Yu Luo; Shan-Fang Ma; Ji-Fu Qu; De-Hu Tian


    BACKGROUND: Gadolinium chloride (GdCl3) selectively in-activates Kupffer cells and protects against ischemia/reperfu-sion and endotoxin injury. However, the effect of Kupffer cell inactivation on liver regeneration after partial liver transplan-tation (PLTx) is not clear. This study was to investigate the role of GdCl3 pretreatment in graft function after PLTx, and to explore the potential mechanism involved in this process. METHODS: PLTx (30% partial liver transplantation) was per-formed using Kamada's cuff technique, without hepatic artery reconstruction. Rats were randomly divided into the control low-dose (5 mg/kg) and high-dose (10 mg/kg) GdCl3 groups. Liver injury was determined by the plasma levels of alanine aminotransferase and aspartate aminotransferase, liver regen-eration by PCNA staining and BrdU uptake, apoptosis by TU-NEL assay. IL-6 and p-STAT3 levels were measured by ELISA and Western blotting. RESULTS: GdCl3 depleted Kupffer cells and decreased animal survival rates, but did not significantly affect alanine amino-transferase and aspartate aminotransferase (P>0.05). GdCl3 pretreatment induced apoptosis and inhibited IL-6 overex-pression and STAT3 phosphorylation after PLTx in graft tissues. CONCLUSION: Kupffer cells may contribute to the liver re-generation after PLTx through inhibition of apoptosis and activation of the IL-6/p-STAT3 signal pathway.

    Cytomegalovirus (CMV) remains one of the most frequent viral infections and the most common cause of death after liver transplantation (LT). Chronic allograft liver rejection remains the major obstacle to long-term allograft survival and CMV infection is one of the suggested risk factors for chronic allograft rejection. The precise relationship between cytomegalovirus and chronic rejection remains uncertain.This review addresses the morbidity of cytomegalovirus infection and the risk factors associated with it, the relationship between cytomegalovirus and chronic allograft liver rejection and the potential mechanisms of it.

    BACKGROUND: Ischemia-related biliary tract complications remain high after orthotopic liver transplantation. Severe ischemic biliary complications often involve the hepatic duct bifurcation and left hepatic duct, resulting finally in obstructive jaundice. Prevention and management of such complications remain a challenge for transplant surgeons. METHODS: All 160 patients were followed up for at least 180 days after transplantation. One-way analysis of variance (ANOVA) and comparative univariate analysis were made using 3 groups (no complications; mild complications;severe complications), to analyze risk factors associated with biliary complications. Multiple logistic regression and linear regression analysis were used to analyze independent risk factors for severe ischemic biliary complications, after excluding other confounding factors. RESULTS: By ANOVA and comparative univariate analysis, the risk factors associated with biliary complications were preoperative bilirubin level (P=0.007) and T-tube stenting of the anastomosis (P=0.016). Multiple logistic regression analysis showed that the use of T-tube and preoperative serum bilirubin were not independent risk factors for severe ischemic biliary complications after orthotopic liver transplantation. Chi-square analysis indicated that in the incidence of severe ischemic biliary lesions, bile duct second warm ischemic time longer than 60 minutes was a significant risk factor. Linear regression demonstrated a negative correlation between cold preservation time and warm ischemia time. CONCLUSIONS: Preoperative serum bilirubin level and the use of T-tube stenting of the anastomosis were independent risk factors for biliary complications after liver transplantation, but not for severe ischemic biliary complications. The second warm ischemia time of bile duct longer than 60 minutes and prolonged bile duct second warm ischemia time combined with cold preservation time were significant risk factors for severe

    BACKGROUND: Hepatic artery thrombosis (HAT) is a frequent complication following liver transplantation, but it is rarely caused by arcuate ligament compression of the celiac artery. This article mainly describes our experience in managing a patient with celiac artery stenosis and HAT after liver transplantation. METHODS: A 44-year-old man with a 15-year history of hepatitis B was admitted to our hospital for hepatocellular carcinoma. Before the operation, he received trans-arterial chemoembolization once, and pretransplant MR angiography indicated a suspected stenosis at the initiation of the celiac artery, while color Doppler showed normal blood lfow in the arterial system. In this case, orthotopic liver transplantation was performed for radical cure of hepatocellular carcinoma. However, B-ultrasonography detected poor blood lfow in the intra- and extra-hepatic artery on the ifrst posttransplant day, and during exploratory laparotomy a thrombus was found in the hepatic artery. Thus, re-transplantation was conducted with a bypass between the graft hepatic artery and the recipient abdominal aorta with the donor's splenic artery. RESULTS: The patient made an uneventful recovery and color Doppler showed good blood lfow in the artery and portal system. Histology conifrmed extensive thrombosis in the left and right hepatic artery of the explanted graft, indicating HAT. CONCLUSIONS: Although HAT caused by celiac trunk compression is rarely reported in liver transplantation, the diagnosis should be considered in patients with pretransplant hepatic artery stenosis on angiography and abnormal blood lfow on B-ultrasonography. Once HAT is formed, treatment such as thrombectomy or re-transplantation should be performed as early as possible.

  15. Transplantation of a 2-year-old deceased-donor liver to a 61-year-old male recipient. (United States)

    The suitable size of a graft is a key element in the success of liver transplantation. A small-for-size liver graft is very likely to sustain a significant degree of injury as a result of ischemia, preservation, reperfusion, and rejection. Usually, small-for-size grafts are a concern in living-donor liver transplantation rather than in deceased-donor liver transplantation. Here, we describe the successful transplantation of a liver from a 2-year-old deceased donor to a 61-year-old male recipient who suffered from liver failure related to hepatitis B. No report of successful deceased-donor liver transplantation with discrepancies between donor and recipient age and size to such an extent has been found in the literature. Despite unusually large discrepancies, with effort in minimizing the ischemic time, revised surgical techniques, and strong regenerative power of the "young" graft, the old patient's liver function gradually returned to normal. This again proves that the definition of a "suitable graft" evolves with time and experience.

We then analyzed pre-transplant demographic and psychiatric characteristics as predictors of post-transplant heavy drinking. Information was obtained from medical records, from nationwide registries.......007), anxiety (p = 0.04), personality disorder (p = 0.05) and no lifetime diagnosis of alcohol dependence (p = 0.03) were associated with heavy drinking after transplantation. Smoking (p = 0.06) tended to be associated, whereas depression (p = 0.7) or being married was not (p = 0.7). In the multivariate...... analysis, only younger age (p = 0.03), being retired (p = 0.007) and no lifetime diagnosis of alcohol dependence (p = 0.003) remained significant predictors. Heavy drinking after transplantation decreased survival beyond 5 years post-transplant (p = 0.004). CONCLUSIONS: There is a high incidence of heavy...

  17. Severe Acute Hyperkalemia during Pre-Anhepatic Stage in Cadaveric Orthotopic Liver Transplantation

    Directory of Open Access Journals (Sweden)

    Mohammad Ali Sahmeddini


    Full Text Available A serious hazard to patients during orthotopic liver transplantation is hyperkalemia. Although the most frequent and hazardous hyperkalemia occurs immediately after reperfusion of the newly transplanted liver, morbid hyperkalemia could happen in the other phases during orthotopic liver transplantation. However, pre-anhepatic hyperkalemia during orthotopic liver transplantation is rare. This report describes one such patient, who without transfusion, developed severe hyperkalemia during pre-anhepatic phase. The variations in serum potassium concentration of the present case indicate that it is necessary to take care of the changes of serum potassium concentration not only during reperfusion but also during the other phases of the liver transplantation.

  18. Liver transplantation for hepatic and neurological Wilson's disease. (United States)

    Geissler, I; Heinemann, K; Rohm, S; Hauss, J; Lamesch, P


    Wilson's disease (WD) is an autosomal-recessive inherited disorder of copper metabolism characterized by excessive deposition of copper throughout the body. If medical treatment fails in cases of fulminant hepatic failure and progressive hepatic dysfunction due to advanced cirrhosis, liver transplantation (OLTx) has been demonstrated to be a valuable treatment option. Between December 1993 and December 2002, 225 OLTxs in 198 patients were performed in our institution. In this consecutive series six patients (three females and three males) were liver grafted for WD. The follow-up ranged from 3 to 7 years. All patients are alive with well-functioning grafts at present. The ceruloplasmin levels increased after transplantation and remained normal. The Kayser-Fleischer ring disappeared in all patients, and urinary copper excretion normalized. The neurological manifestations in the two patients with severe neurological symptoms showed after 2 to 5 years a downward tendency; in one the ataxic movements disappeared completely. The psychiatric disorder in one patient disappeared as well the mild neurological symptoms in the patient with CHILD A cirrhosis. These two patients are fully recovered and returned to work. OLTx should be considered as a treatment option in patients with severe progressive neurological deficits even in cases with stable liver function since liver grafting definitely cures the underlying biochemical defect. In such cases an early decision for liver transplantation is justified because neurological deficits may become irreversible.

  19. Role of ischaemic preconditioning in liver regeneration following major liver resection and transplantation

    Institute of Scientific and Technical Information of China (English)

    D Gomez; S Homer-Vanniasinkam; AM Graham; KR Prasad


    Liver ischaemic preconditioning (IPC) is known to protect the liver from the detrimental effects of ischaemicreperfusion injury (IRI), which contributes significantly to the morbidity and mortality following major liver surgery.Recent studies have focused on the role of IPC in liver regeneration, the precise mechanism of which are not completely understood. This review discusses the current understanding of the mechanism of liver regeneration and the role of IPC in this setting. Relevant articles were reviewed from the published literature using the Medline database. The search was performed using the keywords "liver", "ischaemic reperfusion", "ischaemic preconditioning", "regeneration", "hepatectomy"and "transplantation". The underlying mechanism of liver regeneration is a complex process involving the interaction of cytokines, growth factors and the metabolic demand of the liver. IPC, through various mediators, promotes liver regeneration by up-regulating growthpromoting factors and suppresses growth-inhibiting factors as well as damaging stresses. The increased understanding of the cellular mechanisms involved in IPC will enable the development of alternative treatment modalities aimed at promoting liver regeneration following major liver resection and transplantation.

  20. Recurrence and rejection in liver transplantation for primary sclerosing cholangitis

    Bjarte Fosby; Tom H Karlsen; Espen Melum


    Primary sclerosing cholangitis (PSC) is a chronic progressive inflammatory disease affecting the bile ducts, leading to fibrosis and eventually cirrhosis in most patients. Its etiology is unknown and so far no effective medical therapy is available. Liver transplantation (LTX) is the only curative treatment and at present PSC is the main indication for LTX in the Scandinavian countries. Close to half of the PSC patients experience one or more episodes of acute cellular rejection (ACR) following transplantation and approximately 1/5 of the transplanted patients develop recurrent disease in the graft. In addition, some reports indicate that ACR early after LTX for PSC can influence the risk for recurrent disease. For these important post-transplantation entities affecting PSC patients, we have reviewed the current literature on epidemiology, pathogenesis, treatment and the possible influence of rejection on the risk of recurrent disease in the allograft.

  1. Liver transplantation: where we are and where we are heading. (United States)

    Esquivel, C O


    Outcomes after liver transplantation are outstanding; however, the limiting factor is the shortage of organs. Recently, the utilization of donors after cardiac death has been encouraged; however, such transplants are associated with a high complication rate, mainly a high incidence of biliary complications, particularly ischemic cholangiopahty, a serious complication that often leads to retransplantation. The second problem is the morbidity associated with the use of immunosuppressive drugs. In this manuscript, the current status of clinical protocols for induction of tolerance is briefly discussed. Furthermore, the future of research in transplantation will involve basic scientists and clinical scholars working in concert as has been developed at Stanford School of Medicine with the creation of the Institute for Immunity, Transplantation and Infection.

    Although up to 50% of patients with alcoholic liver disease (ALD) resume alcohol consumption after liver transplantation (LT), numerous studies indicate that long-term results are not compromised. This study focused on evaluating the impact of ALD on outcomes up to and beyond the fifth year after LT. Among the 432 primary LT recipients included in this study, 97 underwent transplantation for ALD. Alcohol relapse rate at 10 yr was 33.5%, with younger recipient age being the only independent predictor (p = 0.019). Survival of patients with ALD (77.0%) was similar to those without (79.0%) up to the fifth post-transplant year (p = 0.655) but worse during the five subsequent years among the five-yr survivors (70.6% vs. 92.9%; p = 0.002). ALD was an independent risk factor for poorer survival beyond the fifth post-transplant year (p = 0.049), but not earlier (p = 0.717). Conversely, alcohol relapse increased the risk of death only during the first five post-transplant years (p = 0.039). There were no significant differences regarding graft failure incidence between ALD and non-ALD recipients up to the fifth post-transplant year (7.3% vs. 11.6%; p = 0.255) and beyond (12.9% vs. 5.0%; p = 0.126). In conclusion, pre-transplant diagnosis of ALD yields negative effects on post-transplant outcomes beyond the fifth post-transplant year, not attributable to recidivism.

  5. Delayed Gastric Emptying after Living Donor Hepatectomy for Liver Transplantation

    Directory of Open Access Journals (Sweden)

    Hanjay Wang


    Full Text Available Delayed gastric emptying is a significant postoperative complication of living donor hepatectomy for liver transplantation and may require endoscopic or surgical intervention in severe cases. Although the mechanism of posthepatectomy delayed gastric emptying remains unknown, vagal nerve injury during intraoperative dissection and adhesion formation postoperatively between the stomach and cut liver surface are possible explanations. Here, we present the first reported case of delayed gastric emptying following fully laparoscopic hepatectomy for living donor liver transplantation. Additionally, we also present a case in which symptoms developed after open right hepatectomy, but for which dissection for left hepatectomy was first performed. Through our experience and these two specific cases, we favor a neurovascular etiology for delayed gastric emptying after hepatectomy.

  6. Recipient aging accelerates acquired transthyretin amyloidosis after domino liver transplantation. (United States)

    Domino liver transplantation (DLT) with liver grafts from patients with hereditary transthyretin (TTR) amyloidosis has been performed throughout the world because of a severe liver graft shortage. Reports of acquired systemic TTR amyloidosis in domino liver recipients have been increasing; however, the precise pathogenesis and clinical course of acquired TTR amyloidosis remains unclear. We analyzed the relationship between the occurrence of acquired amyloidosis and clinical features in 22 consecutive domino liver donors with hereditary TTR amyloidosis (10 males and 12 females; mean age at DLT: 37.2 years; TTR mutations: V30M [n = 19], Y114C [n = 1], L55P [n = 1], and S50I [n = 1]) and 22 liver recipients (16 males and 6 females; mean age at DLT, 46.2 years). The mean times from DLT to amyloid first appearance and transplant recipient symptom onset were 8.2 years and 9.9 years, respectively. Kaplan-Meier analysis and quantification of the amyloid deposition revealed aging of recipients correlated with early de novo amyloid deposition. The sex of donors and recipients and the age, disease duration, and disease severity of donors had no significant effect on the latency of de novo amyloid deposition. In conclusion, our results demonstrate that recipient aging is associated with the early onset de novo amyloidosis. Because acquired amyloidosis will likely increase, careful follow-up for early amyloidosis detection and new treatments, including TTR stabilizers and gene-silencing therapies, are required.

    Full Text Available The number of organ transplantation has increasing worldwide. Several authors have reported an increase in cancer incidence in these patients. There is a marked increase of a variety of tumors. However, common cancers seen in the general population showed no increase. The authors describe a case of a 42-year-old male with alcoholic cirrhosis who underwent orthotopic liver transplantation. The patient developed an uncommon solid tumor two years post transplantation, an epidermoid carcinoma of the pharynx. Radical radiotherapy of the palate was performed and no change was made in immunosuppression therapy. Ten months later the patient is doing well with no evidence of local recurrence or metastatic disease.

  8. Market Competition and Density in Liver Transplantation: Relationship to Volume and Outcomes. (United States)

    Adler, Joel T; Yeh, Heidi; Markmann, James F; Nguyen, Louis L


    Liver transplantation centers are unevenly distributed within the Donor Service Areas (DSAs) of the United States. This study assessed how market competition and liver transplantation center density are associated with liver transplantation volume within individual DSAs. We conducted a retrospective cohort study of 53,156 adult liver transplants in 45 DSAs with 110 transplantation centers identified from the Scientific Registry of Transplant Recipients between 2003 and 2012. The following measures were derived annually for each DSA: market competition using the Herfindahl Hirschman Index, transplantation center density by the Average Nearest Neighbor method, liver quality by the Liver Donor Risk Index, and patient risk by the Model for End-Stage Liver Disease. A hierarchical mixed effects negative binomial regression model of the relationship between liver transplants and market factors was created annually. Patient and graft survival were investigated with a Cox proportional hazards model. Transplantation center density was associated with market competition (p market competition (IRR = 1.36; p = 0.02), increased listings (IRR = 1.14; p market variables were associated with increased mortality after transplantation. After controlling for demographic and market factors, a greater concentration of centers was associated with more liver transplants without impacting overall survival. These results warrant additional investigation into the relationship between geospatial factors and liver transplantation volume with consideration for the optimization of scarce resources.

  9. Living related liver transplant following bone marrow transplantation from same donor: long-term survival without immunosuppression. (United States)

    Granot, E; Loewenthal, R; Jakobovich, E; Gazit, E; Sokal, E; Reding, R


    We report long-term (seven yr) immunological tolerance in a 16-yr-old boy, to a liver allograft donated by his father following a bone marrow transplant at age 2.5 yr from the same donor. The bone marrow transplant was complicated by severe GVHD leading to liver failure and the ensuing need for a liver transplant, performed under planned avoidance of immunosuppression. At one wk post-transplant, although a liver biopsy was histologically compatible with acute rejection, favorable clinical and biochemical evolution precluded initiating immunosuppressive therapy, thus highlighting the need for caution when interpreting early histological changes so that administration of unnecessary immunosuppression can be avoided. Induction of tolerance in transplant recipients remains an elusive goal. In those patients who had received conventional bone marrow transplants and had endured the consequences of GVHD, development of macrochimerism may allow immunosuppression-free solid organ transplantation from the same donor.

  10. Auxiliary partial liver transplantation for acute liver failure using "high risk" grafts: Case report. (United States)

    Duan, Wei-Dong; Wang, Xi-Tao; Wang, Hong-Guang; Ji, Wen-Bin; Li, Hao; Dong, Jia-Hong


    Acute liver failure (ALF) is a reversible disorder that is associated with an abrupt loss of hepatic mass, rapidly progressive encephalopathy and devastating complications. Despite its high mortality, an emergency liver transplantation nowadays forms an integral part in ALF management and has substantially improved the outcomes of ALF. Here, we report the case of a 32-year-old female patient who was admitted with grade IV hepatic encephalopathy (coma) following drug-induced ALF. We performed an emergency auxiliary partial orthotopic liver transplantation with a "high risk" graft (liver macrovesicular steatosis approximately 40%) from a living donor. The patient was discharged on postoperative day 57 with normal liver function. Weaning from immunosuppression was achieved 9 mo after transplantation. A follow-up using CT scan showed a remarkable increase in native liver volume and gradual loss of the graft. More than 6 years after the transplantation, the female now has a 4-year-old child and has returned to work full-time without any neurological sequelae.

  11. Liver graft regeneration in right lobe adult living donor liver transplantation. (United States)

    Optimal portal flow is one of the essentials in adequate liver function, graft regeneration and outcome of the graft after right lobe adult living donor liver transplantation (ALDLT). The relations among factors that cause sufficient liver graft regeneration are still unclear. The aim of this study is to evaluate the potential predisposing factors that encourage liver graft regeneration after ALDLT. The study population consisted of right lobe ALDLT recipients from Chang Gung Memorial Hospital-Kaohsiung Medical Center, Taiwan. The records, preoperative images, postoperative Doppler ultrasound evaluation and computed tomography studies performed 6 months after transplant were reviewed. The volume of the graft 6 months after transplant divided by the standard liver volume was calculated as the regeneration ratio. The predisposing risk factors were compiled from statistical analyses and included age, recipient body weight, native liver disease, spleen size before transplant, patency of the hepatic venous graft, graft weight-to-recipient weight ratio (GRWR), posttransplant portal flow, vascular and biliary complications and rejection. One hundred forty-five recipients were enrolled in this study. The liver graft regeneration ratio was 91.2 +/- 12.6% (range, 58-151). The size of the spleen (p = 0.00015), total portal flow and GRWR (p = 0.005) were linearly correlated with the regeneration rate. Patency of the hepatic venous tributary reconstructed was positively correlated to graft regeneration and was statistically significant (p = 0.017). Splenic artery ligation was advantageous to promote liver regeneration in specific cases but splenectomy did not show any positive advantage. Spleen size is a major factor contributing to portal flow and may directly trigger regeneration after transplant. Control of sufficient portal flow and adequate hepatic outflow are important factors in graft regeneration.

    AIM: To investigate the incidence and risk factors of late-onset acute rejection (LAR) and to clarify the effectiveness of our immunosuppressive regime consisting of life-long administration of tacrolimus and steroids.METHODS: Adult living donor liver transplantation recipients (n = 204) who survived more than 6 mo after living donor liver transplantation were enrolled.Immunosuppression was achieved using tacrolimus and methylprednisolone. When adverse effects of tacrolimus were detected, the patient was switched to cyclosporine. Six months after transplantation,tacrolimus or cyclosporine was carefully maintained at a therapeutic level. The methylprednisolone dosage was maintained at 0.05 mg/kg per day by oral administration.Acute rejections that occurred more than 6 mo after the operation were defined as late-onset. The median followup period was 34 mo.RESULTS: LAR was observed in 15 cases (7%) and no chronic rejection was observed. The incidence of hyperlipidemia, chronic renal failure, new-onset posttransplantation diabetes, and deep fungal infection were 13%, 2%, 24%, and 17%, respectively. Conversion from tacrolimus to cyclosporine was required in 38 patients (19%). Multivariate analysis revealed that a cyclosporinebased regimen was significantly associated with LAR.CONCLUSION: Both LAR and drug-induced adverse events happen at a low incidence, supporting the safety and efficacy of the present immunosuppression regimen for living donor liver transplantation.

    Castaing, Denis; Azoulay, Daniel; Danet, Colette; Thoraval, Laurence; Tanguy Des Deserts, Catherine; Saliba, Faouzi; Samuel, Didier; Adam, René


    To assess acceptance and acceptable estimated mortality levels for right lobe adult-to-adult living related liver transplantation for the medical and allied professions. A paper questionnaire was sent to the physicians practicing with the French Graft Agency (Etablissement Français des Greffes) and to all nurses and ancillary staff of the Paul Brousse Hospital Hepatobiliary Center. Responses were received from surgeons: 38/73; internists specialized in hepatology: 44/120; nurses: 98/100; health care assistants: 45/86; others: 17/20. Acceptance of living donor transplantation is above average for all professional categories and indications may be extended including patients with cancer. Acceptable mortality for the donor was 4%, except among internists (0.7%). Currently, the real risk of mortality for the donor (1%) is lower. Acceptable mortality for the recipient was between 15 and 20%. Acceptance of adult living donor liver transplantation among health care professionals is clearly above average. Thus the psychological involvement of transplantation teams, which is very strong in such situations, should not hamper the development of this type of transplantation.

  15. Nasogastric tube induced refractory epistaxis during liver transplantation

    Yun Hee Kim


    Full Text Available Cirrhosis has many possible manifestations. These signs and symptoms may be either the direct results of liver cell failure or secondary to the resultant portal hypertension. Portal hypertension can decrease the number of platelets, which increases the risk of bleeding.  Additionally, the liver plays a central role in hemostasis, because it is the site of clotting factors synthesis, coagulation inhibitors, and fibrinolytic proteins. Low platelet count and prolonged clotting times may increase the risk of epistaxis arising from minimal trauma, which can cause sometimes serious and occasionally fatal results. We experienced an intraoperative refractory epistaxis in a 60-year-old man with end-stage liver disease (ESLD due to hepatitis B virus-related hepatocellular carcinoma during liver transplantation. The patient started severe epistaxis after we attempted to place a nasogastric (NG tube. We describe successful management of massive epistaxis in an operating room under appropriate anesthesia and close hemodynamic monitoring.   Keywords: End-stage liver disease; Epistaxis; Liver transplantation; Nasogastric tube

  16. Serum ferritin concentration predicts mortality in patients awaiting liver transplantation. (United States)

    Walker, Nicole M; Stuart, Katherine A; Ryan, Rebecca J; Desai, Shireena; Saab, Sammy; Nicol, Jennifer A; Fletcher, Linda M; Crawford, Darrell H G


    Additional markers are required to identify patients on the orthotopic liver transplant (OLT) waiting list at increased risk of death and adverse clinical events. Serum ferritin concentration is a marker of varied pathophysiological events and is elevated with increased liver iron concentration, hepatic necroinflammation, and systemic illness, all of which may cause a deterioration in liver function and clinical status. The aim of this study was to determine whether serum ferritin concentration is an independent prognostic factor in subjects awaiting OLT. This is a dual-center retrospective study. The study cohort consisted of 191 consecutive adults with cirrhosis accepted by the Queensland (Australia) Liver Transplant Service between January 2000 and June 2006 and a validation cohort of 131 patients from University of California Los Angeles (UCLA) Transplant Center. In the study cohort, baseline serum ferritin greater than 200 microg/L was an independent factor predicting increased 180-day and 1-year waiting list mortality. This effect was independent of model for end-stage liver disease (MELD), hepatocellular carcinoma, age, and sex. Subjects with higher serum ferritin had increased frequency of liver-related clinical events. The relationship between serum ferritin and waiting list mortality was confirmed in the UCLA cohort; all deceased patients had serum ferritin greater than 400 microg/L. Serum ferritin greater than 500 microg/L and MELD were independent risk factors for death. Serum ferritin concentration is an independent predictor of mortality-related and liver-related clinical events. Baseline serum ferritin identifies a group of "higher-risk" patients awaiting OLT and should be investigated as an adjunct to MELD in organ allocation.

  17. Accuracy of Hepatobiliary Scintigraphy after Liver Transplantation and Liver Resection

    Directory of Open Access Journals (Sweden)

    Manuel Eckenschwiller


    Full Text Available Background and Aims. Biliary complications are the most frequent complications after common liver surgeries. In this study, accuracy of hepatobiliary scintigraphy (HBS and impact of hyperbilirubinemia were evaluated. Methods. Between November 2007 and February 2016, 131 patients underwent hepatobiliary scintigraphy after having liver surgery. 39 patients with 42 scans after LTX (n=13 or hepatic resection (n=26 were evaluated in the study; 27 were male, with mean age 60 years. The subjects underwent hepatobiliary scintigraphy with Tc-99m labeled Mebrofenin. The results were compared to ERCP as gold standard performed within one month after HBS. We calculated sensitivity, specificity, PPV, and NPV. We compared LTX patients to patients with other liver surgeries. Furthermore the influence of hyperbilirubinemia on HBS scans was evaluated. Results. HBS always provided the correct diagnosis in cases of bile leak in the liver-resected group (14/14. Overall diagnostic accuracy was 76% (19/25 in this group and 54% (7/13 in the LTX group. False negative (FN diagnoses occurred more often among LTX patients (p=0.011. Hyperbilirubinemia (>5 mg/dL significantly influenced the excretion function of the liver, prolonging HBS’s time-activity-curve (p=0.001. Conclusions. Hepatobiliary scintigraphy is a reliable tool to detect biliary complications, but reduced accuracy must be considered after LTX.

  18. Risk factors of acute renal failure after liver transplantation. (United States)

    Cabezuelo, J B; Ramírez, P; Ríos, A; Acosta, F; Torres, D; Sansano, T; Pons, J A; Bru, M; Montoya, M; Bueno, F S; Robles, R; Parrilla, P


    The objective of this study was to determine the risk factors of postoperative acute renal failure (ARF) in orthotopic liver transplantation (OLT). We reviewed 184 consecutive OLT. Postoperative ARF was defined as a persistent rise of 50% increase or more of the S-creatinine (S-Cr). The patients were classified as early postoperative ARF (E-ARF) (first week) and late postoperative ARF (L-ARF) (second to fourth week). Preoperative variables were age, sex, comorbidity, indication for OLT, Child-Pugh stage, united network for organ sharing status, analysis of the blood and urine, and donor's data. Intraoperative variables were systolic arterial pressure, mean arterial pressure, pulmonary capillary wedge pressure, cardiac index, and systemic vascular resistance index. Surgical technique, number of blood products transfused, need for adrenergic agonist drugs, and intraoperative complications were also important. Postoperative variables were duration of stay in the intensive care unit, time on mechanic ventilation, liver graft dysfunction, need for adrenergic agonist drugs, units of blood products infused, episodes of acute rejection, re-operations, and bacterial infections. Firstly we carried out a univariate statistical analysis, and secondly a logistic regression analysis. The risk factors for E-ARF were: pretransplant ARF (odds ratio (OR)=10.2, P=0.025), S-albumin (OR=0.3, P=0.001), duration of treatment with dopamine (OR=1.6, P=0.001), and grade II-IV dysfunction of the liver graft (OR=5.6, P=0.002). The risk factors for L-ARF were: re-operation (OR=3.1, P=0.013) and bacterial infection (OR=2.9, P=0.017). The development of E-ARF is influenced by preoperative factors such as ARF and hypoalbuminemia, as well as postoperative factors such as liver dysfunction and prolonged treatment with dopamine. The predicting factors of L-ARF differ from E-ARF and correspond to postoperative causes such as bacterial infection and surgical re-operation.

  19. Regeneration and Cell Recruitment in an Improved Heterotopic Auxiliary Partial Liver Transplantation Model in the Rat. (United States)

    Auxiliary partial liver transplantation (APLT) in humans is a therapeutic modality used especially to treat liver failure in children or congenital metabolic disease. Animal models of APLT have helped to explore therapeutic options. Though many groups have suggested improvements, standardizing the surgical procedure has been challenging. Additionally, the question of whether graft livers are reconstituted by recipient-derived cells after transplantation has been controversial. The aim of this study was to improve experimental APLT in rats and to assess cell recruitment in the liver grafts. To inhibit recipient liver regeneration and to promote graft regeneration, we treated recipients with retrorsine and added arterial anastomosis. Using green fluorescence protein transgenic rats as recipients, we examined liver resident cell recruitment within graft livers by immunofluorescence costaining. In the improved APLT model, we achieved well-regenerated grafts that could maintain regeneration for at least 4 weeks. Regarding the cell recruitment, there was no evidence of recipient-derived hepatocyte, cholangiocyte, or hepatic stellate cell recruitment into the graft. Macrophages/monocytes, however, were consistently recruited into the graft and increased over time, which might be related to inflammatory responses. Very few endothelial cells showed colocalization of markers. We have successfully established an improved rat APLT model with arterial anastomosis as a standard technique. Using this model, we have characterized cell recruitment into the regenerating grafts.

  20. [The usefulness of angiographic studies in the vascular complications of liver transplantation. The authors' own experience]. (United States)

    Rossi, C; Teodorani, A; Galaverni, M C; Isceri, S; Stefanini, G F; Mazziotti, A; Jovine, E


    The authors report their experience with angiographic techniques in the diagnosis of vascular complications after liver transplantation. From 1986 to 1990, 78 patients were transplanted in our Hospital; of them, 8 underwent angiographic investigations for vascular complications. Angiography is very important when vascular complications are suspected, in the patients with a rise in cytolytic enzymes and in bilirubine levels, with hyperpyrexia, and with bioptic confirmation of no rejection. Duplex US is useful in the evaluation of portal canalization; if there are any doubts, angiography is performed also in the preoperative phase.

  1. Hepatitis Viral Markers in Patients Undergoing Primary Liver Transplants



    The purpose of the study was to determine the prevalence in liver transplant (OLTx) patients of the hepatitis markers (anti-A, anti-B, anti-C, anti-D and HBsAg) and the interrelationships between markers and patients’ sexes, ages, dates of transplant, clinicopathological diagnoses, and short-term survivals. Slightly more than half of the patients were male. Anti-A and anti-B were about evenly distributed between male and female. Anti-C, anti-D, and HBsAg were far more common in males. Age and...

  2. Liver Transplant Tolerance and Its Application to the Clinic: Can We Exploit the High Dose Effect?


    Cunningham, Eithne C.; Sharland, Alexandra F.; G. Alex Bishop


    The tolerogenic properties of the liver have long been recognised, especially in regard to transplantation. Spontaneous acceptance of liver grafts occurs in a number of experimental models and also in a proportion of clinical transplant recipients. Liver graft acceptance results from donor antigen-specific tolerance, demonstrated by the extension of tolerance to other grafts of donor origin. A number of factors have been proposed to be involved in liver transplant tolerance induction, includi...

  3. Brucella infection with pancytopenia after pediatric liver transplantation. (United States)

    Polat, K Y; Tosun, M S; Ertekin, V; Aydinli, B; Emre, S


    Brucellosis is considered the most widespread zoonosis in the world. It has been reported that the prevalence of seropositivity among the Turkish population varies from 3% to 14%. We present a case of brucellosis after pediatric liver transplantation. A 15-year-old boy with the diagnosis of neuro Wilson's disease underwent deceased-donor liver transplantation. The postoperative immunosuppressive protocol consisted of steroids and tacrolimus. Two months after the operation the patient experienced fever to 40°C. The patient complained of poor appetite, headache, and diarrhea. He had had pancytopenia. Despite administration of appropriate antibiotics, antiviral and antifungal agents, fever persisted for > 1 month. Multiple blood, urine, stool, and sputum cultures were negative. Bone marrow aspirate revealed hypocellularity. Liver biopsy was performed, but rejection was not observed on biopsy specimen. Brucella serology was positive and Brucella agglutination titer was 1:320. Bone marrow culture was positive for Brucella but blood culture was negative. The patient was then treated with oral doxycycline and rifampin for 8 weeks. No previous case report about Brucella infection after liver transplantation has appeared in the literature, to our knowledge; our case is presented as the first. Bone marrow hypoplasia is a rare feature of Brucella infection. Our patient with brucellosis and pancytopenia had had hypocellular bone marrow. The clinical and hematologic findings resolved with treatment of the infection. Brucella infection should be suspected in liver transplanted recipients with fever of unknown origin, especially in a recipient who has lived in an endemic area. Brucella also should be considered as a possible diagnosis in patients with pancytopenia.

    AIM:To evaluate the relationship between donor safety and remnant liver volume in right lobe living donor liver transplantation (LDLT).METHODS:From July 2001 to January 2009,our liver transplant centers carried out 197 LDLTs.The clinical data from 151 cases of adult right lobe living donors (not including the middle hepatic vein) were analyzed.The conditions of the three groups of donors were well matched in terms of the studied parameters.The donors' preoperative data,intraoperative and postoperative data were calculated for the three groups:Group 1 remnant liver volume (RLV) < 35%,group 2 RLV 36%-40%,and group 3 RLV > 40%.Comparisons included the different remnant liver volumes on postoperative liver function recovery and the impact of systemic conditions.Correlations between remnant liver volume and post-operative complications were also analyzed.RESULTS:The donors' anthroposomatology data,operation time,and preoperative donor blood test indicators were calculated for the three groups.No significant differences were observed between the donors' gender,age,height,weight,and operation time.According to the Chengdu standard liver volume formula,the total liver volume of group 1 was 1072.88 ± 131.06 mL,group 2 was 1043.84 ± 97.11 mL,and group 3 was 1065.33 ± 136.02 mL.The three groups showed no statistically significant differences.When the volume of the remnant liver was less than 35% of the total liver volume,the volume of the remnant had a significant effect on the recovery of liver function and intensive care unit time.In addition,the occurrence of complications was closely related to the remnant liver volume.When the volume of the remnant liver was more than 35% of the total liver volume,the remnant volume change had no significant effect on donor recovery.CONCLUSION:To ensure donor safety,the remnant liver volume should be greater than the standard liver volume (35%) in right lobe living donor liver transplantation.

  5. Future Economics of Liver Transplantation: A 20-Year Cost Modeling Forecast and the Prospect of Bioengineering Autologous Liver Grafts. (United States)

    Habka, Dany; Mann, David; Landes, Ronald; Soto-Gutierrez, Alejandro


    During the past 20 years liver transplantation has become the definitive treatment for most severe types of liver failure and hepatocellular carcinoma, in both children and adults. In the U.S., roughly 16,000 individuals are on the liver transplant waiting list. Only 38% of them will receive a transplant due to the organ shortage. This paper explores another option: bioengineering an autologous liver graft. We developed a 20-year model projecting future demand for liver transplants, along with costs based on current technology. We compared these cost projections against projected costs to bioengineer autologous liver grafts. The model was divided into: 1) the epidemiology model forecasting the number of wait-listed patients, operated patients and postoperative patients; and 2) the treatment model forecasting costs (pre-transplant-related costs; transplant (admission)-related costs; and 10-year post-transplant-related costs) during the simulation period. The patient population was categorized using the Model for End-Stage Liver Disease score. The number of patients on the waiting list was projected to increase 23% over 20 years while the weighted average treatment costs in the pre-liver transplantation phase were forecast to increase 83% in Year 20. Projected demand for livers will increase 10% in 10 years and 23% in 20 years. Total costs of liver transplantation are forecast to increase 33% in 10 years and 81% in 20 years. By comparison, the projected cost to bioengineer autologous liver grafts is $9.7M based on current catalog prices for iPS-derived liver cells. The model projects a persistent increase in need and cost of donor livers over the next 20 years that's constrained by a limited supply of donor livers. The number of patients who die while on the waiting list will reflect this ever-growing disparity. Currently, bioengineering autologous liver grafts is cost prohibitive. However, costs will decline rapidly with the introduction of new manufacturing

  7. Treatment of osteoporosis in patients with chronic liver disease and in liver transplant recipients. (United States)

    Maalouf, Naim M; Sakhaee, Khashayar


    The pathogenesis of osteoporosis in chronic liver disease and post-liver transplantation is complex and heterogeneous. The development of hepatic osteodystrophy may be related to both increased bone resorption and decreased bone formation. Available medical treatments can be broadly classified into antiresorptive and bone-stimulating agents. Most published studies on the treatment of osteoporosis in patients with liver disease have used the commonly prescribed antiosteoporosis drugs approved for postmenopausal osteoporosis. These studies have included a small number of subjects and used bone mineral density (BMD) changes rather than fracture occurrence as an endpoint because of the short follow-up. Although the increases in BMD are promising, no intervention is proven to have antifracture efficacy in hepatic osteodystrophy. The natural history of bone disease following liver transplantation has not been fully investigated, although studies suggest that bone mineral loss is transient and generally reverses within a year following transplantation. The approach to treatment in liver transplant recipients should be targeted at preventing the early bone loss without interfering with the later recovery. Based on the available data, no single available agent can be considered as first-line therapy. In our opinion, the best treatment approach involves the elucidation of modifiable risk factors and the selection of agents targeted at the underlying derangements.

  8. Successful living donor liver transplantation for acute liver failure after acetylsalicylic acid overdose. (United States)

    A 20-year-old woman was admitted to an emergency hospital after ingesting 66 g of acetylsalicylic acid in a suicide attempt. Although she was treated with gastric lavage, oral activated charcoal, and intravenous hydration with sodium bicarbonate, her hepatic and renal function gradually deteriorated and serum amylase levels increased. Steroid pulse therapy, plasma exchange, and continuous hemodiafiltration did not yield any improvement in her hepatic or renal function, and she was transferred to our hospital for living donor liver transplantation. Nine days after drug ingestion, she developed hepatic encephalopathy: thus, we diagnosed the patient with acute liver failure with hepatic coma accompanied by acute pancreatitis due to the overdose of acetylsalicylic acid. Living donor liver transplantation was immediately performed using a left lobe graft from the patient's mother. Following transplantation, the patient's renal and hepatic function and consciousness improved, and she was discharged. In this report, we describe a rare case of acetylsalicylic acid-induced acute liver failure with acute hepatic coma and concomitant acute pancreatitis and acute renal failure, which were treated successfully with emergency living donor liver transplantation.

  9. Liver transplantation in transthyretin amyloidosis: issues and challenges. (United States)

    Carvalho, Andreia; Rocha, Ana; Lobato, Luísa


    Hereditary transthyretin amyloidosis (ATTR) is a rare worldwide autosomal dominant disease caused by the systemic deposition of an amyloidogenic variant of transthyretin (TTR), which is usually derived from a single amino acid substitution in the TTR gene. More than 100 mutations have been described, with V30M being the most prevalent. Each variant has a different involvement, although peripheral neuropathy and cardiomyopathy are the most common. Orthotopic liver transplantation (OLT) was implemented as the inaugural disease-modifying therapy because the liver produces the circulating unstable TTR. In this review, we focus on the results and long-term outcomes of OLT for ATTR after more than 2063 procedures and 23 years of experience. After successful OLT, neuropathy and organ impairment are not usually reversed, and in some cases, the disease progresses. The overall 5-year survival rate is approximately 100% for V30M patients and 59% for non-ATTR V30M patients. Cardiac-related death and septicemia are the main causes of mortality. Lower survival is related to malnutrition, a longer duration of disease, cardiomyopathy, and a later onset (particularly for males). Deposits, which are composed of a mixture of truncated and full-length TTR (type A) fibrils, have been associated with posttransplant myocardial dysfunction. A higher incidence of early hepatic artery thrombosis of the graft has also been documented for these patients. Liver-kidney/heart transplantation is an alternative for patients with advanced renal disease or heart failure. The sequential procedure, in which ATTR livers are reused in patients with liver disease, reveals that neuropathy in the recipient may appear as soon as 6 years after OLT, and ATTR deposits may appear even earlier. Long-term results of trials with amyloid protein stabilizers or disrupters, silencing RNA, and antisense oligonucleotides will highlight the value and limitations of liver transplantation.

  10. Transjugular liver biopsy: indications, technique and results. (United States)

    Dohan, A; Guerrache, Y; Boudiaf, M; Gavini, J-P; Kaci, R; Soyer, P


    Transjugular liver biopsy is a safe, effective and well-tolerated technique to obtain liver tissue specimens in patients with diffuse liver disease associated with severe coagulopathies or massive ascites. Transjugular liver biopsy is almost always feasible. The use of ultrasonographic guidance for percutaneous puncture of the right internal jugular vein is recommended to decrease the incidence of local cervical minor complications. Semiautomated biopsy devices are very effective in obtaining optimal tissue samples for a precise and definite histological diagnosis with a very low rate of complication. The relative limitations of transjugular liver biopsy are the cost, the radiation dose given to the patient, the increased procedure time by comparison with the more common percutaneous liver biopsy, and the need of a well-trained interventional radiologist.

  11. Auxiliary partial liver transplantation for acute liver failure using "high risk" grafts: Case report


    Duan, Wei-Dong; Wang, Xi-Tao; Wang, Hong-Guang; Ji, Wen-Bin; Li, Hao; Jia-hong DONG


    Acute liver failure (ALF) is a reversible disorder that is associated with an abrupt loss of hepatic mass, rapidly progressive encephalopathy and devastating complications. Despite its high mortality, an emergency liver transplantation nowadays forms an integral part in ALF management and has substantially improved the outcomes of ALF. Here, we report the case of a 32-year-old female patient who was admitted with grade IV hepatic encephalopathy (coma) following drug-induced ALF. We performed ...

  12. Small Bowel and Liver/Small Bowel Transplantation in Children (United States)

    Reyes, Jorge; Tzakis, Andreas G.; Todo, Satoru; Nour, Bakr; Starzl, Thomas E.


    A clinical trial of intestinal transplantation was initiated at the University of Pittsburgh in May 1990. Eleven children received either a combined liver/small bowel graft (n = 8) or an isolated small bowel graft (n = 3). Induction as well as maintenance immunosuppression was with FK-506 and steroids. Four patients were male, and seven were female; the age range was 6 months to 10.2 years. There were 3 deaths (all in recipients of the combined liver/small bowel graft), which were attributed to graft-versus-host disease (n = 1), posttransplant lymphoproliferative disease (n = 1), and biliary leak (n = 1). Transplantation of the intestine has evolved into a feasible operation, with an overall patient and graft survival rate of 73%. These survivors are free of total parenteral nutrition, and the majority are home. These encouraging results justify further clinical trials. PMID:8062049

  13. Marked Transient Alkaline Phosphatemia Following Pediatric Liver Transplantation (United States)

    Koneru, Baburao; Carone, Eduardo; Malatack, J. Jeffrey; Esquivel, Carlos O.; Starzl, Thomas E.


    An isolated marked transient rise in serum alkaline phosphatase levels in otherwise healthy children is a well-documented occurrence. However, in children undergoing liver transplantation, elevated alkaline phosphatase values raise the possibility of biliary obstruction, rejection, or both. During a 6-year period, 6 of 278 children undergoing liver transplantation exhibited a similar phenomenon as an isolated abnormality. None had rejection, biliary obstruction, or other allograft dysfunction during a long follow-up. Eventually and without intervention, the alkaline phosphatase levels returned to normal. These instructive cases suggest that caution be used in advocating Invasive procedures if elevated alkaline phosphatase levels are an isolated abnormality, and close observation with noninvasive testing is recommended.

    A 53-year-old woman developed a subchondral insufficiency fracture of the right femoral head after undergoing a liver transplantation. Radiographs obtained at her first visit demonstrated a slight subchondral collapse in the superolateral portion of the femoral head. Magnetic resonance imaging (MRI) disclosed an irregular, discontinuous, low-intensity band on the T1-weighted image. After 7 months of conservative treatment, the hip pain and the radiograph abnormalities had both disappeared. On the follow-up T1-weighted MR image obtained 17 months after the onset, the band of low signal intensity was not obvious. A subchondral insufficiency fracture is one of the diagnoses to be considered in patients presenting with hip pain after a liver transplantation. (orig.)

  15. Elderly recipients of liver transplantation: impact of age and psychosocial variables on outcome. (United States)

    Niazi, Shehzad; Schneekloth, Terry; Taner, C Burcin


    With expanding experience and success of liver transplantation, increasing numbers of elderly candidates await and undergo liver transplantation. There is accumulating evidence that graft survival and mortality does not appear to differ significantly between the young and carefully selected elderly liver transplantation recipients. Although existing evidence suggests that psychosocial factors impact outcomes after liver transplantation in general, no such information is available specifically for elderly (age ≥65 years) liver transplantation recipients. We conducted a broad medical literature review of outcome studies of elderly liver transplantation recipients. In this review article, we summarize the findings and comment on psychosocial variables included in these studies. Ten outcome studies have reported on the impact of age on the liver transplantation outcomes. There is increasing evidence of favorable outcomes in elderly liver transplantation recipients. Few of these studies include measures of quality of life, functional improvement and other psychosocial variables. Very limited information is available about the impact of psychosocial factors on outcomes in elderly liver transplantation recipients. This dearth of information represents a critical gap in our knowledge and has implications for optimal candidate selection and outcomes after liver transplantation.

  16. Recurrence of primary sclerosing cholangitis in pediatric liver transplant recipients. (United States)

    Venkat, Veena L; Ranganathan, Sarangarajan; Mazariegos, George V; Sun, Qing; Sindhi, Rakesh


    There is little detailed clinical information on recurrent primary sclerosing cholangitis (rPSC) after liver transplantation in children. Our purpose was to describe the characteristics of children who had experienced rPSC after liver transplantation so that we could identify potential risk factors for recurrence. Clinical information for pediatric patients undergoing transplantation for primary sclerosing cholangitis (PSC) was retrospectively reviewed, and variables related to the pretransplant diagnosis of PSC and posttransplant variables were abstracted. The studied variables included the following: cytomegalovirus/Epstein-Barr virus status, early/late rejection, induction regimen, immunosuppression in the first year, steroid-resistant rejection, diagnosis of inflammatory bowel disease, and human leukocyte antigen markers commonly associated with PSC. A diagnosis of rPSC was made on the basis of radiographic features, histology, or both. Twelve patients underwent liver transplantation for PSC between 1993 and 2012. Patients received tacrolimus for maintenance immunosuppression after induction with steroids (n = 6) or thymoglobulin (n = 6). Three patients were diagnosed with rPSC 44, 60, and 62 months after transplantation. A fourth patient underwent retransplantation for graft failure with features of both hepatic artery stenosis and rPSC. This patient had distinct histological features of rPSC in the second graft. Three of the 4 patients were 7 years old or younger at the diagnosis of PSC. The patient and graft survival rates were similar for the steroid and thymoglobulin groups. All 4 children with rPSC received steroid-free thymoglobulin induction. In conclusion, our observation of an association between thymoglobulin, and age less than 10 years at the diagnosis of PSC, and rPSC adds to the existing suggestion of a link between the immune environment and the pathogenesis of rPSC. Defining the natural history of rPSC and searching for the etiology and

    Full Text Available BACKGROUND AND AIM: Intraperitoneal transplantation of alginate-microencapsulated human hepatocytes is an attractive option for the management of acute liver failure (ALF providing short-term support to allow native liver regeneration. The main aim of this study was to establish an optimised protocol for production of alginate-encapsulated human hepatocytes and evaluate their suitability for clinical use. METHODS: Human hepatocyte microbeads (HMBs were prepared using sterile GMP grade materials. We determined physical stability, cell viability, and hepatocyte metabolic function of HMBs using different polymerisation times and cell densities. The immune activation of peripheral blood mononuclear cells (PBMCs after co-culture with HMBs was studied. Rats with ALF induced by galactosamine were transplanted intraperitoneally with rat hepatocyte microbeads (RMBs produced using a similar optimised protocol. Survival rate and biochemical profiles were determined. Retrieved microbeads were evaluated for morphology and functionality. RESULTS: The optimised HMBs were of uniform size (583.5±3.3 µm and mechanically stable using 15 min polymerisation time compared to 10 min and 20 min (p<0.001. 3D confocal microscopy images demonstrated that hepatocytes with similar cell viability were evenly distributed within HMBs. Cell density of 3.5×10(6 cells/ml provided the highest viability. HMBs incubated in human ascitic fluid showed better cell viability and function than controls. There was no significant activation of PBMCs co-cultured with empty or hepatocyte microbeads, compared to PBMCs alone. Intraperitoneal transplantation of RMBs was safe and significantly improved the severity of liver damage compared to control groups (empty microbeads and medium alone; p<0.01. Retrieved RMBs were intact and free of immune cell adherence and contained viable hepatocytes with preserved function. CONCLUSION: An optimised protocol to produce GMP grade alginate

  1. Echinocandin Resistance in Candida Species Isolates from Liver Transplant Recipients. (United States)

    Prigent, Gwénolé; Aït-Ammar, Nawel; Levesque, Eric; Fekkar, Arnaud; Costa, Jean-Marc; El Anbassi, Sarra; Foulet, Françoise; Duvoux, Christophe; Merle, Jean-Claude; Dannaoui, Eric; Botterel, Françoise


    Liver transplant recipients are at risk of invasive fungal infections, especially candidiasis. Echinocandin is recommended as prophylactic treatment but is increasingly associated with resistance. Our aim was to assess echinocandin drug resistance in Candida spp. isolated from liver transplant recipients treated with this antifungal class. For this, all liver-transplanted patients in a University Hospital (Créteil, France) between January and June of 2013 and 2015 were included. Susceptibilities of Candida isolates to echinocandins were tested by Etest and the EUCAST reference method. Isolates were analyzed by FKS sequencing and genotyped based on microsatellites or multilocus sequence typing (MLST) profiles. Ninety-four patients were included, and 39 patients were colonized or infected and treated with echinocandin. Echinocandin resistance appeared in 3 (8%) of the treated patients within 1 month of treatment. One patient was colonized by resistant Candida glabrata, one by resistant Candida dubliniensis, and one by resistant Candida albicans Molecular analysis found three mutations in FKS2 HS1 (F659S, S663A, and D666E) for C. glabrata and one mutation in FKS1 HS1 (S645P) for C. dubliniensis and C. albicans Susceptible and resistant isolates belonged to the same genotype. To our knowledge, this is the first study on echinocandin resistance in Candida spp. in a liver transplant population. Most resistant isolates were found around/in digestive sites, perhaps due to lower diffusion of echinocandin in these sites. This work documents the risk of emergence of resistance to echinocandin, even after short-term treatment. Copyright © 2017 Prigent et al.

  2. Gabapentin withdrawal syndrome in a post-liver transplant patient. (United States)

    Finch, Christopher K; Eason, James; Usery, Justin B


    A 41-year-old male with a previous orthotopic liver transplant began experiencing insomnia, anxiety, diaphoresis, headaches, and palpitations that progressed over a 2-day period. As part of his home medication regimen, the patient was taking gabapentin for peripheral neuropathy. His acute onset of increasing symptoms coincided with an inadvertent discontinuation of gabapentin. After reinitiation of gabapentin therapy, the symptoms slowly improved over the next 24 hours and the episode of gabapentin withdrawal syndrome resolved.

  3. Medicaid enrollment after liver transplantation: Effects of medicaid expansion. (United States)

    Tumin, Dmitry; Hayes, Don; Washburn, W Kenneth; Tobias, Joseph D; Black, Sylvester M


    Liver transplantation (LT) recipients in the United States have low rates of paid employment, making some eligible for Medicaid public health insurance after transplant. We test whether recent expansions of Medicaid eligibility increased Medicaid enrollment and insurance coverage in this population. Patients of ages 18-59 years receiving first-time LTs in 2009-2013 were identified in the United Network for Organ Sharing registry and stratified according to insurance at transplantation (private versus Medicaid/Medicare). Posttransplant insurance status was assessed through June 2015. Difference-in-difference multivariate competing-risks models stratified on state of residence estimated effects of Medicaid expansion on Medicaid enrollment or use of uninsured care after LT. Of 12,837 patients meeting inclusion criteria, 6554 (51%) lived in a state that expanded Medicaid eligibility. Medicaid participation after LT was more common in Medicaid-expansion states (25%) compared to nonexpansion states (19%; P expansion (January 1, 2014), the hazard of posttransplant Medicaid enrollment increased in states participating in Medicaid expansion (hazard ratio [HR] = 1.5; 95% confidence interval [CI] = 1.1-2.0; P = 0.01), but not in states opting out of Medicaid expansion (HR = 0.8; 95% CI = 0.5-1.3; P = 0.37), controlling for individual characteristics and time-invariant state-level factors. No effects of Medicaid expansion on the use of posttransplant uninsured care were found, regardless of private or government insurance status at transplantation. Medicaid expansion increased posttransplant Medicaid enrollment among patients who had private insurance at transplantation, but it did not improve overall access to health insurance among LT recipients.

  4. Update and actual trends on bacterial infections following liver transplantation

    Institute of Scientific and Technical Information of China (English)

    Jose Luis del Pozo


    Recent advances in effective antimicrobial prophylactic strategies have led to a decline in the incidence of opportunistic infections in liver transplant recipients.However, morbidity and mortality due to infectious diseases remain as major problems. Bacterial infections occurring early after transplant are mainly related to the technical aspects of the procedure. By contrast,after the first postoperative days and beyond, the nature and variety of infectious complications change.Opportunistic bacterial infections are uncommon after 6 mo in patients receiving stable and reduced maintenance doses of immunosuppression with good graft function and little is documented about these cases in the literature. Transplant recipients may be more susceptible to some pathogens, such as the Nocardia species, Legionella species, Listeria monocytogenes , Mycoplasma species, Salmonella species or Rhodococcus equi. Respiratory infections due to capsulated bacteria, such as Streptococcus pneumoniae and Haemophilus influenza, can be lifethreatening if not promptly treated in this population.These late bacterial infections may be very difficult to recognize and treat in this population. In this article,we review what has been described in the literature with regards to late bacterial infections following liver transplantation.

  5. Still's Disease in a Pediatric Patient after Liver Transplantation

    Directory of Open Access Journals (Sweden)

    Juan-Carlos Meza


    Full Text Available Still's disease (SD is a multisystemic inflammatory disease characterized by persistent arthritis and in many cases with fever of unknown origin. Diagnosis of SD is challenging because of nonspecific characteristics and especially in the case of a patient with solid organ transplantation and immunosuppressive therapy where multiple causes of fever are possible. There is no diagnostic test for SD, even though some useful diagnostic criteria or laboratory findings, such as serum ferritin levels, have been proposed, and useful imaging studies for the diagnosis or followup of SD have not been developed. We report the case of a 9-year-old child who presented with high grade fever associated with joint pain after a history of liver transplantation and immunosuppressive therapy. Laboratory tests showed increased acute phase reactants, elevated ferritin, and leukocytosis. An 18 F-fluorodeoxyglucose positron emission tomography (18F-FDG PET was performed identifying abnormal hypermetabolic areas localized in spleen, transplanted liver, and bone marrow secondary to inflammatory process. All infectious, autoimmune, and malignant causes were ruled out. A diagnosis of SD was performed and a steroid-based regimen was initiated with adequate response and no evidence of recurrence. To our knowledge this is the first case of SD following a solid organ transplant.

    Herden, Uta; Ganschow, Rainer; Briem-Richter, Andrea; Helmke, Knut; Nashan, Bjoern; Fischer, Lutz


    Nowadays, most paediatric liver transplant recipients receive a split or other technical variant graft from adult deceased or live donors, because of a lack of available age- and size matched paediatric donors. Few data are available, especially for liver grafts obtained from very young children (transplantations between 1989 and 2009. Recipients were divided into five groups (1-5) depending on donor age (transplantations from deceased donors were performed; 1- and 5-year graft survival rates were 75%, 80%, 78%, 81%, 74% and 75%, 64%, 70%, 67%, 46%, and 1- and 5-year patient survival rates were 88%, 91%, 90%, 89%, 78% and 88%, 84%, 84%, 83%, 63% for groups 1-5, respectively, without significant difference. Eight children received organs from donors younger than 1 year and 45 children received organs from donors between 1 and 6 years of age. Overall, vascular complications occurred in 13.2% of patients receiving organs from donors younger than 6 years. Analysis of our data revealed that the usage of liver grafts from donors younger than 6 years is a safe procedure. The outcome was comparable with grafts from older donors with excellent graft and patient survival, even for donors younger than 1 year.

    Ozçay, Figen; Canan, Oğuz; Bilezikçi, Banu; Torgay, Adnan; Karakayali, Hamdi; Haberal, Mehmet


    We described six children with heritable liver disease and hepatocellular carcinoma treated with living-related liver transplantation. Underlying liver diseases were type-1 tyrosinemia (three patients), progressive familial intrahepatic cholestasis type II (two patients), and Wilson's disease (one patient). Two of the tumors were found incidentally during liver transplantation. Number of nodules was 12, 15, 3, 2, and 1 (in two patients). Three patients were treated with chemotherapy before the procedure. Chemotherapy was not given to any patient after liver transplantation. The mean follow-up was 17.7 +/- 6 months (range: 7-24). All patients are tumor recurrence free. Both graft and patient survival rates are 100% at a median of 18.5 months follow-up. Physicians in charge of treating children with heritable liver disease should screen them periodically for the development of hepatocellular carcinoma. Liver transplantation may offer these children better survival rates.

    In 2011, a pilot program for deceased organ donation was initiated in China. We describe the first successful series of liver transplants in the pilot program. From July 2011 to August 2012, our center performed 26 liver transplants from a pool of 29 deceased donors. All organ donation and allograft procurement were conducted according to the national protocol. The clinical data of donors and recipients were collected and summarized retrospectively. Among the 29 donors, 24 were China Category II donors (organ donation after cardiac death), and five were China Category III donors (organ donation after brain death followed by cardiac death). The recipients were mainly the patients with hepatocellular carcinoma. The one-year patient survival rate was 80.8% with a median follow-up of 422 (2-696) days. Among the five mortalities during the follow-up, three died of tumor recurrence. In terms of post-transplant complications, 9 recipients (34.6%) experienced early allograft dysfunction, 1 (3.8%) had non-anastomotic biliary stricture, and 1 (3.8%) was complicated with hepatic arterial thrombosis. None of these complications resulted in patient death. Notably, primary non-function was not observed in any of the grafts. With careful donor selection, liver transplant from deceased donors can be performed safely and plays a critical role in overcoming the extreme organ shortage in China.

    AIM: To assess the value of pre-transplant artificial liver support in reducing the pre-operative risk factors relating to early mortality after orthotopic liver transplantation (OLT).METHODS: Fifty adult patients with various stages and various etiologies undergoing OLT procedures were treated with molecular adsorbent recycling system (MARS) as preoperative liver support therapy. The study included two parts, the first one is to evaluate the medical effectiveness of single MARS treatment with some clinical and laboratory parameters, which were supposed to be the therapeutical pre-transplant risk factors, the second part is to study the patients undergoing OLT using the regression analysis on preoperative risk factors relating to early mortality (30 d)after OLT.RESULTS: In the 50 patients, the statistically significant improvement in the biochemical parameters was observed (pre-treatment and post-treatment). Eight patients avoided the scheduled Ltx due to significant relief of clinical condition or recovery of failing liver function, 8 patients died, 34 patients were successfully bridged to Ltx, the immediate outcome of this 34patients within 30d observation was: 28 kept alive and 6patients died.CONCLUSION: Pre-operative SOFA, level of creatinine,INR, TNF-α, IL-10 are the main preoperative risk factors that cause early death after operation, MARS treatment before transplantion can relieve these factors significantly.

    The European trial investigating normothermic ex vivo liver perfusion (NEVLP) as a preservation technique for liver transplantation (LT) uses gelofusine, a non-US Food and Drug Administration-approved, bovine-derived, gelatin-based perfusion solution. We report a safety and feasibility clinical NEVLP trial with human albumin-based Steen solution. Transplant outcomes of 10 human liver grafts that were perfused on the Metra device at 37 °C with Steen solution, plus 3 units of erythrocytes were compared with a matched historical control group of 30 grafts using cold storage (CS) as the preservation technique. Ten liver grafts were perfused for 480 minutes (340-580 minutes). All livers cleared lactate (final lactate 1.46 mmol/L; 0.56-1.74 mmol/L) and produced bile (61 mL; 14-146 mL) during perfusion. No technical problems occurred during perfusion, and all NEVLP-preserved grafts functioned well after LT. NEVLP versus CS had lower aspartate aminotransferase and alanine aminotransferase values on postoperative days 1-3 without reaching significance. No difference in postoperative graft function between NEVLP and CS grafts was detected as measured by day 7 international normalized ratio (1.1 [1-1.56] versus 1.1 [1-1.3]; P = 0.5) and bilirubin (1.5; 1-7.7 mg/dL versus 2.78; 0.4-15 mg/dL; P = 0.5). No difference was found in the duration of intensive care unit stay (median, 1 versus 2 days; range, 0-8 versus 0-23 days; P = 0.5) and posttransplant hospital stay (median, 11 versus 13 days; range, 8-17 versus 7-89 days; P = 0.23). Major complications (Dindo-Clavien ≥ 3b) occurred in 1 patient in the NEVLP group (10%) compared with 7 (23%) patients in the CS group (P = 0.5). No graft loss or patient death was observed in either group. Liver preservation with normothermic ex vivo perfusion with the Metra device using Steen solution is safe and results in comparable outcomes to CS after LT.

  15. Liver transplant outcomes using ideal donation after circulatory death livers are superior to using older donation after brain death donor livers. (United States)

    Scalea, Joseph R; Redfield, Robert R; Foley, David P


    Multiple reports have demonstrated that liver transplantation following donation after circulatory death (DCD) is associated with poorer outcomes when compared with liver transplantation from donation after brain death (DBD) donors. We hypothesized that carefully selected, underutilized DCD livers recovered from younger donors have excellent outcomes. We performed a retrospective study of the United Network for Organ Sharing database to determine graft survivals for patients who received liver transplants from DBD donors of age ≥ 60 years, DBD donors  60 years old. Careful donor organ and recipient selection can lead to excellent results, despite previous reports suggesting otherwise. Increased acceptance of these DCD livers would lead to shorter wait list times and increased national liver transplant rates. Liver Transplantation 22 1197-1204 2016 AASLD.

  16. Liver transplantation in Taiwan: the Chang Gung experience. (United States)

    Chen, C L; Wang, K L; Hui, Y L; Shieh, W B


    Between March 1984 and February 1991, six orthotopic liver transplantations were performed at the Chang Gung Memorial Hospital in Taiwan. The indications for transplantation were Wilson's disease (5 patients) and biliary atresia (1 patient). Donors and recipients were matched only for size and ABO blood group compatibility, and the recipient operations were performed without the use of a venovenous bypass. Arterial reconstruction was carried out by end-to-end hepatic artery anastomosis (4), thoracic aortic conduit (1), or interposition of an iliac artery graft (1), whereas biliary reconstruction was accomplished by a choledochocholedochostomy using a T-tube stent (4) or a choledochocholedochostomy using an external cholecystostomy without stenting (2). Biliary complications occurred in three patients, and all required additional surgery. The average duration of donor-liver cold ischemia, operating time, and blood loss during surgery were 7 h and 50 min (range, 4.5-9 h), 13.5 h (range, 11.8-17 h), and 4,385 ml (range, 750-12,000 ml), respectively. The immunosuppressive regimens included a cyclosporin-steroid combination (n = 2) and a triple-drug combination (n = 4). All except one of the surviving patients experienced at least one rejection episode that was reversed by a methyl-prednisolone bolus and/or recycle. One patient developed a primary cytomegalovirus (CMV) infection that responded well to Ganciclovir treatment. Two of the patients died, one of injuries sustained in a traffic accident 3 years after transplantation, and the other of massive upper gastrointestinal bleeding. The overall survival value at 3 months was 83%, and the follow-up period ranged from 3 months to 7 years. All of the survivors have achieved complete rehabilitation and currently enjoy an excellent quality of life with normal liver function. Although the present study involved a small number of cases, our results indicate that liver transplantation can be successfully achieved in a high

  17. Hypophosphatemia after Right Hepatectomy for Living Donor Liver Transplantation

    Directory of Open Access Journals (Sweden)

    Kelly W Burak


    Full Text Available Hypophosphatemia has been described in patients undergoing right hepatectomy for liver cancer and in living donors for liver transplantation who also received total parenteral nutrition. At the study centre, significant hypophosphatemia (0.36 mmol/L or less requiring intravenous replacement was seen in two of the first nine living donors for adult-to-adult liver transplantation. To determine the frequency of hypophosphatemia in living donors, the authors obtained phosphate levels on stored serum samples from postoperative days 0, 1, 3 and 7 in all nine patients, none of whom were on total parenteral nutrition. Within the first week, hypophosphatemia developed in 55.6% of patients and phosphate levels returned to normal by day 7 in all nine patients. One patient had normal phosphate levels during the first week, but had profound hypophosphatemia (0.32 mmol/L on day 14 when he presented with a Staphylococcus aureus infection of a bile collection and significant hypoxemia. The extent of hepatectomy and the rate of liver regeneration, estimated by baseline and postoperative day 7 volumetric computed tomography scans, did not correlate with the development of hypophosphatemia. In conclusion, hypophosphatemia is common in living donors undergoing right hepatectomy and may be associated with complications. All living donors should be monitored for the development of hypophosphatemia during the first two postoperative weeks.

    Full Text Available Background: Cardiovascular abnormalities are among common complication in patients with cirrhosis waiting for liver transplantation (LT. The aim of the present study was to investigate cardiac abnormalities among pediatric liver transplant candidates.Methods: We prospectively evaluated the pediatric patient aged less than 18 years listed for LT between 2006 and 2008. Besides history taking and physical examination all the patients underwent electrocardiogram, chest radiograph, contrast echocardiography and color Doppler echocardiography, as well as arterial blood gas analyses.Results: Totally 89 patients with mean age of 8.1±4.6 years were included in the study. The most common causes for liver disease were cryptogenic cirrhosis followed by biliary atresia and autoimmune cirrhosis. Clubbing was found in 27 out of 89 patients and was the most common abnormalities in physical examination. In 22 patients (24.7% heart murmur was heard by a pediatric cardiologist. Sixty nine patients (77.5% had normal cardiac findings in chest radiograph. Cardiomegaly was found in 17 (19.1% patients as the most common abnormal finding in chest radiograph. Electrocardiogram showed sinus tachycardia in 16 (18% patients. Eleven patients (12.4% had tricuspid regurgitation as the most common abnormal findings in echocardiography. Thirteen (14.6% patients had positive contrast echocardiography in favor of intrapulmonary shunt.Conclusion: As the leading cause of post transplant death after graft rejection are cardiovascular complications cardiac evaluation should be considered in all pediatric patients before LT to lower morbidity and mortality during and after transplantation.

    BACKGROUND: Hepatocellular carcinoma (HCC) is a heterogeneous malignancy with multiple etiologies, high incidence, and high mortality. The standard surgical management for patients with HCC consists of locoregional ablation, surgical resection, or liver transplantation, depending on the background state of the liver. Eighty percent of patients initially presenting with HCC are unresectable, either due to the extent of tumor or the level of underlying hepatic dysfunction. While in patients with no evidence of cirrhosis and good hepatic function resection has been the surgical treatment of choice, it is contraindicated in patients with moderate to severe cirrhosis. Liver transplantation is the optimal surgical treatment. DATA  SOURCES: PubMed search of recent articles (from January 2000 to March 2011) was performed looking for relevant articles about hepatocellular carcinoma and its treatment. Additional articles were identified by evaluating references from selected articles. RESULTS: Here we review criteria for transplantation, the types, indications, and role of locoregional therapy in treating the cancer and in downstaging for possible later transplantation. We also summarize the contribution of immunosuppression and adjuvant chemotherapy in the management and prevention of HCC recurrence. Finally we discuss recent advances in imaging, tumor biology, and genomics as we delineate the remaining challenges for the diagnosis and treatment of this disease. CONCLUSIONS: Much can be improved in the diagnosis and treatment of HCC. A great challenge will be to improve patient selection to criteria based on tumor biology. Another will be to incorporate systemic agents post-operatively in patients at high risk for recurrence, paying close attention to efficacy and safety. The future direction of the effort in treating HCC will be to stimulate prospective trials, develop molecular imaging of lymphovascular invasion, to improve recipient selection, and to investigate

    AIM: To investigate whether hepatocytes isolated from macroscopically normal liver during hepatic resection for neoplasia could provide a novel source of healthy hepatocytes, including the development of reliable protocols for malignant cells removal from the hepatocyte preparation.METHODS: Hepatocytes were procured from resected liver of 18 patients with liver tumors using optimised digestion and cell-enrichment protocols. Suspensions of various known quantities of the HT-29 tumor cell line and patient hepatocytes were treated or not with Ep-CAM-antibody-coated immunomagnetic beads in order to investigate the efficacy of tumor-purging by immunomagnetic depletion, using a semi-quantitative RT-PCR method developed to detect tumor cells.Immunomagnetic bead-treated or bead-untreated tumor cell-hepatocyte suspensions were transplanted intra-peritoneally in Balb/C nude mice to assess the rates of tumor development.RESULTS: Mean viable hepatocyte yield was 9.3 x 106 cells per gram of digested liver with mean viability of 70.5%. Immunomagnetic depletion removed tumor cells to below the RT-PCR detection-threshold of 1 tumor cell in 106 hepatocytes, representing a maximum tumor purging efficacy of greater than 400000-fold.Transplanted, immunomagnetic bead-purged tumor cell-hepatocyte suspensions did not form peritoneal tumors in Balb/C nude mice. Co-transplantation of hepatocytes with tumor cells did not increase tumorigenesis of the tumor cells.CONCLUSION: Immunomagnetic depletion appears to be an effective method of purging contaminating tumor cells to below threshold for likely tumorigenesis.Along with improved techniques for isolation of large numbers of viable hepatocytes, normal liver resected for neoplasia has potential as another clinically useful source of hepatocytes for transplantation.

  1. Cholesterol metabolism in cholestatic liver disease and liver transplantation:From molecular mechanisms to clinical implications

    The aim of this review is to enlighten the critical roles that the liver plays in cholesterol metabolism. Liver transplantation can serve as gene therapy or a source of gene transmission in certain conditions that affect cholesterol metabolism, such as low-density-lipoprotein(LDL) receptor gene mutations that are associated with familial hypercholesterolemia. On the other hand, cholestatic liver disease often alters cholesterol metabolism. Cholestasis can lead to formation of lipoprotein X(Lp-X), which is frequently mistaken for LDL on routine clinical tests. In contrast to LDL, Lp-X is non-atherogenic, and failure to differentiate between the two can interfere with cardiovascular risk assessment, potentially leading to prescription of futile lipid-lowering therapy. Statins do not effectively lower Lp-X levels, and cholestasis may lead to accumulation of toxic levels of statins. Moreover, severe cholestasis results in poor micellar formation, which reduces cholesterol absorption, potentially impairing the cholesterol-lowering effect of ezetimibe. Apolipoprotein B-100 measurement can help distinguish between atherogenic and non-atherogenic hypercholesterolemia. Furthermore, routine serum cholesterol measurements alone cannot reflect cholesterol absorption and synthesis. Measurements of serum non-cholesterol sterol biomarkers- such as cholesterol precursor sterols, plant sterols, and cholestanol- may help with the comprehensive assessment of cholesterol metabolism. An adequate cholesterol supply is essential for liver-regenerative capacity. Low preoperative and perioperative serum cholesterol levels seem to predict mortality in liver cirrhosis and after liver transplantation. Thus, accurate lipid profile evaluation is highly important in liver disease and after liver transplantation.

  6. Caudal shif ting of hepatic vein anastomosis inright liver living donor liver transplantation

    Institute of Scientific and Technical Information of China (English)

    Sheung Tat Fan


    BACKGROUND: In right liver living donor liver trans-plantation, hepatic venous anastomosis is performed using the recipient's right hepatic vein oriifce. There may be situations that the portal vein is short or the right liver graft is small, leading to dififculty in portal vein, hepatic artery or duct-to-duct anastomosis. METHODS: The recipient's right hepatic vein oriifce is closed partially for 2 cm at the cranial end or totally, and a new venotomy is made caudal to the right hepatic vein oriifce. Hepatic vein anastomosis is performed with the new venotomy. RESULTS: The distance between the liver graft hilum and hepatoduodenal ligament is reduced. Portal vein, hepatic artery and biliary anastomosis could be performed without tension or conduit. CONCLUSION: Caudal shifting of hepatic vein anasto-mosis facilitates implantation of a right liver living donor graft.

  7. Patients seeking liver transplant turn to China: outcomes of 15 Egyptian patients who went to China for a deceased-donor liver transplant. (United States)

    Abdeldayem, Hesham M; Salama, Ibrahim; Salaa, Ibrahim; Soliman, Sayed; Gameel, Khaled; Gabal, Ashraf Abo; El Ella, Khaled Abo; Helmy, Amr


    Increasing numbers of Egyptians with end-stage liver disease seek liver transplants in China because of lower costs and shorter wait times.We evaluated outcomes of Egyptian patients who underwent liver transplants in China and address ethical concerns. Fifteen Egyptian patients (11 men, 4 women; mean age, 52 years) who underwent liver transplants in China were included. Preoperative data before traveling to China, reports from China, and follow-up data upon return were reviewed. Indications included hepatitis-C-related liver cirrhosis (n=9), hepatitis-C-related liver cirrhosis with hepatocellular carcinoma (n=4), and hepatitis-B-related liver cirrhosis (n=2). Nine patients were evaluated for living-related liver transplant but none of their potential donors was suitable. Three patients had advanced hepatocellular carcinoma and were not accepted for living-related liver transplant by any Egyptian center. Two patients had no living-related donor. One patient refused a living-related liver transplant in Egypt and elected to get a whole liver graft from China. Overall survival rate was 80.0% at 6 months and 73.3% at 12 months. There were 4 deaths; 2 occurred in China. Of the 11 surviving patients, 9 (82%) developed complications. Nineteen complications were seen in the 13 patients who were managed after returning from China. Major complications necessitating prolonged hospitalizations occurred in 4 patients. Two patients required further laparotomy. Although deceased-donor liver transplant in China could be an option for Egyptian patients with end-stage liver disease, patients and clinicians should be aware of potential outcomes and related ethical issues.

  8. Decision support for organ offers in liver transplantation. (United States)

    Volk, Michael L; Goodrich, Nathan; Lai, Jennifer C; Sonnenday, Christopher; Shedden, Kerby


    Organ offers in liver transplantation are high-risk medical decisions with a low certainty of whether a better liver offer will come along before death. We hypothesized that decision support could improve the decision to accept or decline. With data from the Scientific Registry of Transplant Recipients, survival models were constructed for 42,857 waiting-list patients and 28,653 posttransplant patients from 2002 to 2008. Daily covariate-adjusted survival probabilities from these 2 models were combined into a 5-year area under the curve to create an individualized prediction of whether an organ offer should be accepted for a given patient. Among 650,832 organ offers from 2008 to 2013, patient survival was compared by whether the clinical decision was concordant or discordant with model predictions. The acceptance benefit (AB)--the predicted gain or loss of life by accepting a given organ versus waiting for the next organ--ranged from 3 to -22 years (harm) and varied geographically; for example, the average benefit of accepting a donation after cardiac death organ ranged from 0.47 to -0.71 years by donation service area. Among organ offers, even when AB was >1 year, the offer was only accepted 10% of the time. Patient survival from the time of the organ offer was better if the model recommendations and the clinical decision were concordant: for offers with AB > 0, the 3-year survival was 80% if the offer was accepted and 66% if it was declined (P decision support may improve patient survival in liver transplantation. © 2015 American Association for the Study of Liver Diseases.

    Background Increasing evidence suggests that the intestinal microbiota plays an important role in liver diseases. However, the dynamics of the intestinal microbiota during liver transplantation (LT) and its potential role in clinical course remain unknown. Methods We prospectively analyzed the intestinal microbiota of 38 patients who underwent LT in Kyoto University Hospital. We characterized the microbial compositions of fecal specimens from LT patients using a metagenomics approach by an Illumina MiSeq platform. We analyzed the diversity of microbiota sequentially from pretransplantation until 2 months after LT and also compared the microbiota during an episode of acute cellular rejection (ACR) and bloodstream infections (BSI) to the microbial composition of time-matched fecal specimens obtained from patients who did not experience ACR or BSI, respectively. Results Three hundred twenty fecal specimens were analyzed. Dynamic changes were observed in the microbial composition of LT recipients during the perioperative period. Over the course of LT, the mean diversity index decreased during the first 3 weeks after LT and gradually increased during our observation period. The loss of intestinal microbiota diversity was associated with high Child-Pugh scores, high model for end-stage liver disease scores, ACR, and BSI. At the family level, Bacteroides, Enterobacteriaceae, Streptococcaceae, and Bifidobacteriaceae were increased whereas Enterococcaceae, Lactobacillaceae, Clostridiaceae, Ruminococcaceae, and Peptostreptococcaceae were decreased in ACR patients. Conclusions The microbiota of LT patients was associated with the severity of liver diseases and the presence of ACR and BSI. These results lay the groundwork for more comprehensive investigations of microbiota characteristics to identify diagnostic markers for transplant health and to guide intervention strategies to improve transplant outcomes.

    AlM: Liver transplantation is indicated for Wilson's disease(WD) patients with the fulminant form and end-stage liverfailure. The aim of this study was to review our experiencewith living-related liver transplantation (LRLT) for WD.METHODS: A retrospective review was made for WDundergoing LRLT at our hospital from January 2001 toFebuary 2003.RESULTS: LRLT was carried out in 15 patients with WD,one of them had fulminant hepatic failure and the others had end-stage hepatic insufficiency. The mean age of the patients was 14.5±2.5 years (range 6 to 20 years). All the recipients had low serum ceruloplasmin levels with a mean value of 126.8±34t.8 mg/L before transplantation. The serum ceruloplasmin levels increased to an average of 238.6±34.4mg/L after LRLT at the latest evaluation, between 2 and 27months after transplantation. A marked reduction in urinary copper excretion was observed in all the recipients after transplantation. Among the eight recipients with preoperative Kayser-Fleischer (K-F) rings, this abnormality resolved completely after LRLT in five patients and partially in three.All the recipients are alive and remain well, and none has developed signs of recurrent WD after a mean follow-up period of 15.4±9.3 months (range 2-27 months) except one who died of severe rejection. The donors were 14t mothers and 1 father. The serum ceruloplasmin levels were within normal limits in all the donors (mean: 220±22.4 mg/L). The mean donor age was 35.0±4.0 years (range, 30 to 45 years).Two donors had biliary leakage and required reoperation.Grafts were harvested as follows: four right lobe grafts without hepatic middle vein and eleven left lobe grafts with hepatic middle vein. The grafts were blood group-compatible in all recibents. Two patients had hepatic artery thrombosis and underwent retransplantation.CONCLUSION: LRLT is a curative procedure in Wilson's disease manifested as fulminant hepatic failure and/or endstage hepatic insufficiency.

    Cholangiocarcinoma is a malignant tumor of the biliary system that can be classified into intrahepatic(i CCA),perihiliar(ph CCA) and distal. Initial experiences with orthotopic liver transplantation(OLT) for patientswith i CCA and ph CCA had very poor results and this treatment strategy was abandoned. In the last decade,thanks to a strict selection process and a neoadjuvant chemoradiation protocol,the results of OLT for patients with non-resectable phC CA have been shown to be excellent and this strategy has been extended worldwide in selected transplant centers. Intrahepatic cholangiocarcinoma is a growing disease in most countries and can be diagnosed both in cirrhotic and in non-cirrhotic livers. Even though OLT is contraindicated in most centers,recent investigations analyzing patients that were transplanted with a misdiagnosis of HCC and were found to have an iC CA have shown encouraging results. There is some information suggesting that patients with early stages of the disease could benefit from OLT. In this review we analyze the current stateof-the-art of OLT for cholangiocarcinoma as well as the new insights and future perspectives.

  12. A single-center experience with retrograde reperfusion in liver transplantation. (United States)

    Kniepeiss, Daniela; Iberer, Florian; Grasser, Barbara; Schaffellner, Silvia; Stadlbauer, Vanessa; Tscheliessnigg, Karl-Heinz


    Poor graft function secondary to injury by ischemia and reperfusion remains a major problem with regard to morbidity and mortality in clinical liver transplantation (LTX). Up to one fifth of patients suffer from poor initial liver function due to severe damage to hepatocytes. This situation leads either to primary nonfunction described in approximately 6% of LTX or to slow recovery. We present a new method of reperfusion during LTX. From July 1998 to July 2002, 42 LTX in 39 recipients, (10 female, 52 years old (26-70) were performed. LTX was carried out in piggy-back technique. After completing the piggy-back anastomosis, the caval vein was declamped immediately, and retrograde low pressure reperfusion of the graft with low oxygenated venous blood was established. Portal anastomosis was performed using a running suture. In order to provide optimal retrograde liver perfusion, no clamping of the donor portal vein was done. After completing portal anastomosis, the recipient portal vein was declamped immediately. During arterial anastomosis, the transplanted liver was antegradely perfused via the portal vein. After completing hepatic artery anastomosis, declamping of the hepatic artery was done and arterial perfusion started. No backtable or in-situ-flushing except the described reperfusion technique was performed. Forty-two LTX in 39 recipients using piggy-back technique and retrograde reperfusion via the caval vein followed by antegrade reperfusion via the portal vein were performed; 38 out of 39 patients (97.44%) were alive and well at day 8 after LTX. One patient (2.56%) died of a pre-existing portal vein thrombosis on day 2 after LTX. Three patients had to undergo retransplantation for hepatic artery thrombosis (7.14%). Liver enzymes, bilirubine, prothrombine time and AT III on day 1, 3, 5 and 8 after LTX showed favourable values. Median aspartate aminotransferase (ASAT) was 219 U/l on day 1 after LTX. One-month survival rate was 95.23%, and 1-year survival rate

    Transplantation for Wilson's disease occupies 1/3 of the cases for metabolic diseases in Japan. At the end of 2009, 109 transplantations had been performed including three deceased donor cases in the Japanese registry. We herein discuss problems of transplantation for Wilson's disease as well as its indication, timing, and social care. We retrospectively reviewed four fulminant cases and two chronic cases who underwent living donor liver transplantation. There were two boys and two girls. Four adolescents of average age 11.3 years underwent living donor liver transplantation. Duration from onset to transplantation ranged from 10 to 23 days. Average Model for End-stage Liver Disease (MELD) score was 27.8 (range=24-31). All patients were administrated chelates prior to transplantation. MELD, New Wilson's index, Japanese scoring for liver transplantation, and liver atrophy were useful tools for transplantation decision making; however, none of them was an independent decisive tool. Clinical courses after transplantation were almost uneventful. One girl, however, developed an acute rejection episode due to noncompliance at 3 years after transplantation. All patients currently survive without a graft loss. No disease recurrence had been noted even using living related donors. Two adults evaluated for liver transplantation were listed for deceased donor liver transplantation. Both candidates developed cirrhosis despite long-term medical treatment. There were no appropriate living donors for them. There are many problems in transplantation for Wilson's disease. The indications for liver transplantation should be considered individually using some decision-making tools. The safety of the living donor should be paid the most attention.

  14. Liver transplantation in patients with portal vein thrombosis. (United States)

    Manzanet, G; Sanjuán, F; Orbis, P; López, R; Moya, A; Juan, M; Vila, J; Asensi, J; Sendra, P; Ruíz, J; Prieto, M; Mir, J


    The aim of this study is to analyze the incidence, risk factors, management, and follow-up of patients with portal vein thrombosis (PVT) undergoing primary orthotopic liver transplantation (OLT). Four hundred fifteen OLTs were performed in 391 patients. In 62 patients, partial (group 1; n = 48) or complete (group 2; n = 14) PVT was found at the time of surgery. Portal flow was reestablished by venous thrombectomy. In this study, we compare 62 primary OLTs performed in patients with PVT at the time of OLT with a group of 329 primary OLTs performed in patients without PVT (group 3) and analyze the incidence of PVT, use of diagnostic methods, surgical management, and outcome. We found no significant differences among the 3 groups for length of surgery, cold and warm ischemic times, and postoperative stay in the intensive care unit. With the piggyback technique, groups 1 and 2 had greater blood losses and required more blood transfusions than group 3. The early reoperation rate was greater in group 2. The incidence of rethrombosis was 4.8% (group 1, 2%; group 2, 14.3%). Reexploration and thrombectomy (2 patients) and retransplantation (1 patient) had a 100% mortality rate. In particular, the mortality rate of patients with complete PVT with extension into the splanchnic veins is high (33%). Three-month and 4-year patient survival rates were statistically similar in the 3 groups. The presence of PVT at the time of OLT is not a contraindication for OLT. However, if PVT extends into the splanchnic veins, the outcome is guarded.

  15. Surgical procedures for a rat model of partial orthotopic liver transplantation with hepatic arterial reconstruction. (United States)

    Nagai, Kazuyuki; Yagi, Shintaro; Uemoto, Shinji; Tolba, Rene H


    Orthotopic liver transplantation (OLT) in rats using a whole or partial graft is an indispensable experimental model for transplantation research, such as studies on graft preservation and ischemia-reperfusion injury, immunological responses, hemodynamics, and small-for-size syndrome. The rat OLT is among the most difficult animal models in experimental surgery and demands advanced microsurgical skills that take a long time to learn. Consequently, the use of this model has been limited. Since the reliability and reproducibility of results are key components of the experiments in which such complex animal models are used, it is essential for surgeons who are involved in rat OLT to be trained in well-standardized and sophisticated procedures for this model. While various techniques and modifications of OLT in rats have been reported since the first model was described by Lee et al. in 1973, the elimination of the hepatic arterial reconstruction and the introduction of the cuff anastomosis technique by Kamada et al. were a major advancement in this model, because they simplified the reconstruction procedures to a great degree. In the model by Kamada et al., the hepatic rearterialization was also eliminated. Since rats could survive without hepatic arterial flow after liver transplantation, there was considerable controversy over the value of hepatic arterialization. However, the physiological superiority of the arterialized model has been increasingly acknowledged, especially in terms of preserving the bile duct system and the liver integrity. In this article, we present detailed surgical procedures for a rat model of OLT with hepatic arterial reconstruction using a 50% partial graft after ex vivo liver resection. The reconstruction procedures for each vessel and the bile duct are performed by the following methods: a 7-0 polypropylene continuous suture for the supra- and infrahepatic vena cava; a cuff technique for the portal vein; and a stent technique for the

    Aim: To determine whether glycine could downregulate interleukin 1 receptor associated kinase-4 (IRAK-4) expression to interfere with lipopolysaccharides (LPS) signal transduction and blunt transplantative liver ischemia-reperfusion injury (I/RI). Methods: SD rats were randomly divided into two groups: donor animals of the glycine group (n=40) were given glycine (1.5 mL; 300 mmol/L, iv) 1 h before harvest, and the control group were treated with 1.5 mL physiological saline (n= 40). Orthotropic liver transplantation was then performed according to the Kamada technique. Ten animals in each group were followed up for 7 d after surgery to assess survival. The remaining animals in each group were divided into 3 subgroups (n=10) at 1h, 2 h and 6 h after portal vein reperfusion. Levels of LPS, serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and total bilirubin in portal circulation, as well as IRAK-4 and TNF-α expression, NF-кB transcriptional activity and morphological study of liver tissues were analyzed. Results: Reperfusion resulted in a significant elevation of LPS concentrations in each group persisting to the end of our study. However, glycine, which led to improved survival rate and liver function, significantly alleviated liver parenchyma cell damage by downregulating IRAK-4, TNF-α expression and NF-кB transcriptional activity compared with the control group. Conclusion: Glycine can attenuate hepatic I/RI by downregulating IRAK-4 to interfere with LPS signal transduction.

    In the field of pediatric living donor liver transplantation, the indications for apheresis and dialysis, and its efficacy and safety are still a matter of debate. In this study, we performed a retrospective investigation of these aspects, and considered its roles. Between January 2008 and December 2010, 73 living donor liver transplantations were performed in our department. Twenty seven courses of apheresis and dialysis were performed for 19 of those patients (19/73; 26.0%). The indications were ABO incompatible-liver transplantation in 11 courses, fluid management in seven, acute liver failure in three, renal replacement therapy in two, endotoxin removal in two, cytokine removal in one, and liver allograft dysfunction in one. Sixteen courses of apheresis and dialysis were performed prior to liver transplantation for 14 patients. The median IgM antibody titers before and after apheresis for ABO blood type-incompatible liver transplantation was 128 and eight, respectively (P apheresis and dialysis were performed post liver transplantation for 10 patients. The median PaO2/FiO2 ratio before and after dialysis for fluid overload was 159 and 339, respectively (P apheresis and dialysis occurred. The 1-year survival rate of the patients was 100%. Apheresis and dialysis in pediatric living donor liver transplantation are effective for antibody removal in ABO-incompatible liver transplantation, and fluid management for acute respiratory failure.

    AIM: To evaluate the impact of early steroid withdrawal on the incidence of rejection, tumor recurrence and complications after liver transplantation for advanced-stage hepatocellular carcinoma. METHODS: Fifty-four patients underwent liver transplantation for advanced-stage hepatocellular carcinoma from April 2003 to June 2005. These cases were divided into a steroid-withdrawal group (group A, n = 28) and a steroid-maintenance group (group B, n = 26). In group A, steroid was withdrawn 3 mo after transplantation. In group B, steroid was continuously used postoperatively. The incidence of rejection, 6-mo and 1-year recurrence rate of carcinoma, 1-year survival rate, mean serum tacrolimus trough level, and liver and kidney function were compared between the two groups. RESULTS: In the two groups, no statistical difference was observed in the incidence of rejection (14.3 vs 11.5%, P > 0.05), mean serum tacrolimus trough levels (6.9 ± 1.4 vs 7.1 ± 1.1 μg/L, P > 0.05), liver and kidney function after 6 mo [alanine aminotransferase (ALT): 533 ± 183 vs 617 ± 217 nka/L, P > 0.05; creatinine: 66 ± 18 vs 71 ± 19 μmol/L, P > 0.05], 6-mo recurrence rate of carcinoma (25.0 vs 42.3%, P > 0.05), and 1-year survival rate (64.2 vs 46.1%, P > 0.05). The 1-year tumor recurrence rate (39.2 vs 69.2%, P < 0.05), serum cholesterol level (3.9 ± 1.8 vs 5.9 ± 2.6 mmol/L, P < 0.01) and fasting blood sugar (5.1 ± 2.1 vs 8.9 ± 3.6 mmol/L, P < 0.01) were significantly different. These were lower in the steroid-withdrawal group than in the steroid-maintenance group. CONCLUSION: Early steroid withdrawal was safe after liver transplantation in patients with advanced-stage hepatocellular carcinoma. When steroids were withdrawn 3 mo post-operation, the incidence of rejection did not increase, and there was no demand to maintain tacrolimus at a high level. In contrast, the tumor recurrence rate and the potential of adverse effects decreased significantly. This may have led to an increase

  19. Approach to a case of multiple irregular red cell antibodies in a liver transplant recipient: Need for developing competence

    Directory of Open Access Journals (Sweden)

    Ravi C Dara


    Full Text Available Liver transplant procedure acts as a challenge for transfusion services in terms of specialized blood components, serologic problems, and immunologic effects of transfusion. Red cell alloimmunization in patients awaiting a liver transplant complicate the process by undue delay or unavailability of compatible red blood cell units. Compatible blood units can be provided by well-equipped immunohematology laboratory, which has expertise in resolving these serological problems. This report illustrates resolution of a case with multiple alloantibodies using standard techniques, particularly rare antisera. Our case re-emphasizes the need for universal antibody screening in all patients as part of pretransfusion testing, which helps to identify atypical antibodies and plan for appropriate transfusion support well in time. We recommend that the centers, especially the ones that perform complex procedures like solid organ transplants and hematological transplants should have the necessary immunohematological reagents including rare antisera to resolve complex cases of multiple antibodies as illustrated in this case.

  20. Calcineurin inhibitor minimisation versus continuation of calcineurin inhibitor treatment for liver transplant recipients

    DEFF Research Database (Denmark)

    Penninga, Luit; Wettergren, Andre; Chan, An-Wen;


    The therapeutic success of liver transplantation has been largely attributable to the development of effective immunosuppressive treatment regimens. In particular, calcineurin inhibitors were essential in reducing acute rejection and improving early survival. Currently, more than 90% of all liver...

    BACKGROUND:Infectious complications are common during the postoperative course of a liver transplant recipient. Malaria, however, is a rare complication in such a setting. METHOD:We report post-transplantation malaria causing elevation of liver enzymes in two recipients. RESULTS:Both patients who had undergone living donor liver transplantation showed elevated levels of liver enzymes and fever during the postoperative course. Investigations (including liver biopsy in one patient) were initially inconclusive in determining the cause of liver dysfunction. The diagnosis of malaria was established in both cases by peripheral blood smear. Liver function transiently worsened with antimalarial treatment but subsequently became normal. CONCLUSION:This report highlights the importance of excluding such uncommon causes of post-transplantation liver dysfunction, especially when either the recipient or the donor comes from a region endemic for malaria.

    Hemochromatosis predisposes to dilated or restrictive cardiomyopathy which can progress to end-stage heart failure, requiring the use of advanced heart therapies including heart (HT) and heart liver (HLT) transplantation. Little is known about the characteristics and outcomes of these patients. We queried the United Network for Organ Sharing (UNOS) registry for all patients listed for HT or HLT for a diagnosis of 'hemochromatosis' between 1987 and 2014. Waitlist and post-transplantation outcomes were compared between patients with hemochromatosis (HT vs HLT) and other etiologies. Of the 81,356 adults listed for heart transplantation, 23 patients with hemochromatosis were identified (16 listed for HLT; and 7 listed for HT). Compared with other etiologies, HC patients were younger (39 vs 51years, p<0.0001), and more likely to need inotropes (56.5% vs 25.6%, p=0.003) and mechanical ventilation (13% vs 3.4%, p=0.041). Cumulative hazards of waitlist mortality or delisting were higher in hemochromatosis patients than for other etiologies of heart failure (p<0.001). There were 4 HT and 4 HLT during the study period. Post-transplantation, patients with HC had a 1- and 2-year cumulative survival of 88% and 75%, respectively. Both HT and HLT are viable options for patients with hemochromatosis. Patients with hemochromatosis are younger with increased wait-list mortality compared with other etiologies. Copyright © 2017 Elsevier B.V. All rights reserved.

    Background Because of the lack of brain death laws in China, the proportion of cadaveric organ donation is low. Many patients with end-stage liver disease die waiting for a suitable donor. Living donor liver transplantation (LDLT) would reduce the current discrepancy between the number of patients on the transplant waiting list and the number of available organ donors. We describe the early experience of LDLT in the mainland of China based on data from five liver transplant centers.Methods Between January 2001 and October 2003, 45 patients with end-stage liver disease received LDLT at five centers in China. The indication and timing, surgical techniques and complications, nonsurgical issues including rejection, infection, and advantages of LDLT in the series were reviewed. Actuarial patient and graft survival rates were calculated by using the Kaplan-Meier product-limit estimate. Statistical analysis was completed by using SPSS 10.0.Results All LDLT recipients were cirrhotic patients, except for one man with fulminant hepatic failure. Among the 45 cases of LDLT, 35 (77.8%) were performed in one center (the First Affiliated Hospital of Nanjing Medical University). The overall 1 and 3 year survival rate of the recipients was 93.1% and 92.0%, respectively. Of the 45 LDLT donors, there were 3 cases of biliary leakage, 2 subphrenic collections, 1 fat liquefaction around the incision and 1 biliary peritonitis after T tube removal. All donors recovered completely.Conclusions LDLT provides an excellent approach to addressing the problem of donor shortage in China even though the operation is complicated, uncompromising and difficult with respect to the safety of the donors and receptors. Despite early technical hurdles having been overcome, perfection of technique is still necessarily. At present, LDLT is a good choice for the patients with irreversible liver disease.

    Plasma proteome is widely used in studying changes occurring in human body during disease or other disturbances. Immunological methods are commonly used in such studies. In recent years, mass spectrometry has gained popularity in high-throughput analysis of plasma proteins. In this study, we tested whether mass spectrometry and iTRAQ-based protein quantification might be used in proteomic analysis of human plasma during liver transplantation surgery to characterize changes in protein abundances occurring during early graft reperfusion. We sampled blood from systemic circulation as well as blood entering and exiting the liver. After immunodepletion of six high-abundant plasma proteins, trypsin digestion, iTRAQ labeling, and cation-exchange fractionation, the peptides were analyzed by reverse phase nano-LC-MS/MS. In total, 72 proteins were identified of which 31 could be quantified in all patient specimens collected. Of these 31 proteins, ten, mostly medium-to-high abundance plasma proteins with a concentration range of 50-2000 mg/L, displayed relative abundance change of more than 10%. The changes in protein abundance observed in this study allow further research on the role of several proteins in ischemia-reperfusion injury during liver transplantation and possibly in other surgery.

    Abnormalities of pulmonary gas exchange are common in patients with advanced liver disease. Since arterial blood hypoxemia is an important issue in the preoperative evaluation of liver transplant candidates, the study was undertaken to determine the incidence and severity of lung function impairment with a special emphasis on pulmonary gas exchange abnormalities in this group of patients. 104 consecutive patients (47 F and 57 M, mean age 46 +/-11 yr) listed for orthotopic liver transplantation participated in this prospective study. All patients underwent evaluation including: clinical assessment (Child-Pough and MELD classification), chest X-ray, chest sonography, lung function tests, arterial blood gases measurement, and transthoracic contrast enhanced echocardiography. There were 2 patients with acute hepatic failure, 6 patients with primary or metastatic liver carcinoma, and 96 patients with chronic liver disease. The mean PaO(2) and lung function parameters for the entire group were within normal limits. There were 29 hypoxemic patients (PaO(2)20 mmHg) P(A-a)O(2). DL(CO) was significantly lower in cirrhotic vs. non-cirrhotic patients (76.5 +/-19.3 vs. 92.4 +/-19.0% predicted; P<0.001). Hepatopulmonary syndrome (HPS) was recognized in 23 (24%) patients. 91% of patients with HPS showed mild to moderate stage of disease. There were significant difference between differences HPS patients and non-HPS patients in DL(CO) (69.0 +/-14.5 vs. 83.5 +/-20.7, P<0.01). In conclusion, all patients referred for OLT should be screened for gas exchange abnormalities. Such a workup should include not only PAO(2) but also DL(CO) and P(A-a)O(2) measurement together with contrast enhanced echocardiography.

  8. Measuring Coping Behavior in Liver Transplant Candidates: A Psychometric Analysis of the Brief COPE. (United States)

    Amoyal, Nicole; Fernandez, Anne C; Ng, Reuben; Fehon, Dwain C


    Liver transplant candidates must cope with significant physiological and psychological challenges. The Brief COPE is a frequently used measure of coping behavior; however, knowledge of the scale's factor structure and construct validity is limited with regard to liver transplant candidates. This study assessed the validity of the Brief COPE in 120 liver transplant candidates using exploratory factor analysis. Results revealed a 6-factor solution, only 2 of which were consistent with the original scale assignments. Construct validity of the 6 Brief COPE scales yielded in this study was demonstrated. The results indicate that the Brief COPE is valid, reliable, and can be meaningfully interpreted in liver transplant patients. Future research should confirm this factor structure and examine its predictive validity prior to widespread use among liver transplant patients. Suggestions are presented for enhancing the care of transplant candidates by promoting the use of adaptive coping mechanisms to manage distress.

    The aim of this study was to determine the accuracy of contrast-enhanced biphasic spiral CT as a screening tool in the preoperative evaluation of orthotopic liver transplant (OLT) patients. Spiral-CT examinations were performed before liver transplantation in 53 patients. Scans were retrospectively reviewed and compared with pathologic findings in fresh-sectioned livers. When findings between spiral CT and pathology were discordant, formalized livers were reexamined with lesion-by lesion evaluation. Fresh pathologic evaluation revealed 23 liver lesions (16 HCC, 7 macro-regenerative nodules). Malignancy was identified in 13 of 53 patients (24.5%). Pre-transplantation spiral CT depicted 27 liver lesions (23 HCC, 4 macro-regenerative nodules). Malignancy was suspected in 14 patients (26.4%). In 10 of 53 (18.9%), spiral CT and pathologic evaluation were discordant. Subsequent retrospective pathologic evaluation showed malignancy in 4 additional patients. Spiral CT compared with the retrospective pathologic findings revealed 36 real-negative, 14 real-positive, 0 false-positive, and 3 false-negative patients with malignancy. Sensitivity and specificity of spiral CT in detection of malignancy was 82 and 100%, respectively. Contrast-enhanced biphasic spiral CT is an accurate technique in the evaluation of patients preceding OLT. Routine fresh-sectioned liver pathologic findings are not as sensitive as previously estimated. (orig.)

    Full Text Available Population-based evidence of the relative risk of cancer among heart, kidney, and liver transplant recipients from Asia is lacking. The Taiwan National Health Insurance Research Database was used to conduct a population-based cohort study of transplant recipients (n = 5396, comprising 801 heart, 2847 kidney, and 1748 liver transplant recipients between 2001 and 2012. Standardized incidence ratios and Cox regression models were used. Compared with the general population, the risk of cancer increased 3.8-fold after heart transplantation, 4.1-fold after kidney transplantation and 4.6-fold after liver transplantation. Cancer occurrence showed considerable variation according to transplanted organs. The most common cancers in all transplant patients were cancers of the head and neck, liver, bladder, and kidney and non-Hodgkin lymphoma. Male recipients had an increased risk of cancers of the head and neck and liver, and female kidney recipients had a significant risk of bladder and kidney cancer. The adjusted hazard ratio for any cancer in all recipients was higher in liver transplant recipients compared with that in heart transplant recipients (hazard ratio = 1.5, P = .04. Cancer occurrence varied considerably and posttransplant cancer screening should be performed routinely according to transplanted organ and sex.

    Full Text Available Abstract Objective Liver injury due to trauma is a rare indication for transplantation. The main indications in such cases were uncontrollable bleeding and insufficient hepatic function. Because of poor results, liver transplantation in these patients is occasionally described as "waste of organs", however based on insufficient data. This study aims to report our experience and to critically question the indication of transplantation in these patients. Methods All liver transplantations at our institution were reviewed retrospectively. This covered 1,529 liver transplants between September 1987 and December 2008. Of them, 6 transplants were performed due to motor-vehicle accidents which caused uncontrollable acute liver trauma in 4 patients. The patients' peri-operative course, short- and long-term outcomes were analyzed. Results Five deceased-donor liver transplantations (4 full size, 1 split and 1 living donor (right transplantation were performed. The median GCS score was 9/15; the median MELD score was 15. Postoperative complications were observed in 3 patients, requiring re-operation in 2. After a median (range follow-up of 32.95 (10.3-55.6 months, 2 patients are alive and remain well on immunosuppression. Conclusion Liver transplantation in patients with otherwise surgically uncontrollable acute liver injury can be indicated as a life saving procedure and can be performed successfully in highly selected cases.

    So far numerous post-transplant outcome predictors have been studied to decrease the loss of resources and grafts after organ transplantation. The role of education, as a predictor, in liver transplantation outcome has so far been studied in several articles. However, in most of the studies it was evaluated as a surrogate for socioeconomic status or other variants. The absolute impact of parents' education has rarely been studied. Adult patients are their own caregivers whereas pediatric liver transplantation recipients are mostly cared by their parents. To evaluate the effect of level of patients' education on the mortality and morbidity of pediatric liver transplant recipients. We studied a group of 91 children who had undergone liver transplantation in our center from March 21, 2012 to July 21, 2013. In this retrospective study, patients' medical charts and questionnaire were used to collect the necessary data. Post-transplantation mortality and complications were divided into two categories: Early (Parents' educational level was also categorized into 5 groups. Multivariate analysis of all groups showed that paternal education is an independent predictor of the late post-transplantation complications (p=0.024). Educational level of children's mothers had no significant correlation with the late post-transplantation complications (p=0.45). Neither maternal (p=0.59) nor paternal (p=0.607) education had significant effect on the late post-transplantation mortality. Paternal educational level of liver transplanted children is associated with the late post-transplantation complications.

    We wanted to valuate the mid-term therapeutic results of percutaneous transhepatic balloon angioplasty for portal vein stenosis after liver transplantation. From May 1996 to Feb 2005, 420 patients underwent liver transplantation. Percutaneous transhepatic angioplasty of the portal vein was attempted in six patients. The patients presented with the clinical signs and symptoms of portal venous hypertension or they were identified by surveillance doppler ultrasonography. The preangioplasty and postangioplasty pressure gradients were recorded. The therapeutic results were monitored by the follow up of the clinical symptoms, the laboratory values, CT and ultrasonography. The overall technical success rate was 100%. The clinical success rate was 83% (5/6). A total of eight sessions of balloon angioplasty were performed in six patients. The mean pressure gradient decreased from 14.5 mmHg to 2.8 mmHg before and after treatment, respectively. The follow up periods ranged from three months to 64 months (mean period; 32 months). Portal venous patency was maintained in all six patients until the final follow up. Combined hepatic venous stenosis was seen in one patient who was treated with stent placement. One patient showed puncture tract bleeding, and this patient was treated with coil embolization of the right portal puncture tract via the left transhepatic portal venous approach. Percutaneous transhepatic balloon angioplasty is an effective treatment for the portal vein stenosis that occurs after liver transplantation, and our results showed good mid-term patency with using this technique.
