RESUMO

BACKGROUND: Portal vein anastomotic complications related to size discrepancy are important causes of morbidity and mortality in pediatric liver transplantation. Interposed vascular grafts in portal vein anastomosis can solve this problem. The aim of this study is to evaluate the results of pediatric liver transplantations performed using cryopreserved interposed vascular grafts between graft portal vein and superior mesenteric vein (SMV)-splenic vein (SpV) confluence. METHODS: Twenty-nine pediatric patients received liver transplantation using cryopreserved venous grafts in our Liver Transplant Institute between 2013 and 2020 were included in this study. Demographic, clinical, and operative characteristics and postoperative follow-up were analyzed. RESULTS: Sixteen patients (55.2%) had portal hypoplasia and five patients (17.2%) had portal vein thrombosis. In total, six patients (20.6%) suffered portal vein thrombosis in the early postoperative period. Three patients (10.3%) experienced portal vein thrombosis in the late postoperative period. Late portal vein thrombosis rate was significantly higher in patients with early portal vein thrombosis (3/6 patients [50%] versus 0/23 patients [0%]; p = .034). Lack of portal flow was significantly higher in patients with both early (50% versus 0%; p = .002) and late portal vein thrombosis (66.7% versus 6.7%; p = .03). CONCLUSION: Preoperative portal vein thrombosis and insufficient flow are important factors affecting success of liver transplant in children. The use of interposed vein grafts in problematic portal anastomoses can overcome portal flow problems.

RESUMO

Diaphragmatic hernias (DHs) are rare complications after pediatric liver transplantation (PLT). It is now widely accepted that DHs after liver transplantation (LT) is a pediatric related condition. PLTs (under of age 18) performed between January 2013 and June 2019 at Malatya Inonu University Institute of Liver Transplantation were retrospectively scanned. Study group consisting DHs and a control group were compared. Among 280 PLTs, 8 of them were complicated with DHs (%2.9). Median age of the patients with DH was 3.0 (0.8-9.5) years. Median graft recipient weight ratio was 2.5 (0.9-4.4). Five patients were below 5th percentiles in terms of pediatric weight growth chart at the time of LT. Also, 6 patients were below 5th percentiles in terms of pediatric height growth chart. There was no statistical difference between study and control groups. There are many risk factors mentioned in literature that may be primarily responsible for DHs after PLT. These factors are left lobe and large-for-size grafts, malnutrition, trauma or diathermy of diaphragmatic nerve and vessels and immunosuppressants. In our study, we could not specify any reason that differs in DHs. In our aspect, narrow diaphragma and thorax are exposed to high intra-abdominal pressure from abdomen. Large-for-size grafts, which are specific to children, also may contribute to this affect. Excessive diathermy and trauma to diaphragmatic collaterals may aggravate the risk of DH. More patients are needed to make an exact conclusion, in order to evaluate with comparable study on this aspect.

RESUMO

BACKGROUND: To share our experience with hollow viscus migration of artificial vascular grafts (AVG) used for venous reconstruction of the right anterior sector in living donor liver transplantations (LDLT). METHODS: Clinical, radiological, and endoscopic data of 13 right lobe LDLT patients (range: 26-67 years) with a diagnosis of postoperative AVG migration into adjacent hollow viscus were analyzed. RESULTS: Biliary complications were detected in 12 patients. A median of four times endoscopic retrograde cholangiopancreatography (ERCP) procedures were performed in 11 patients prior to AVG migration diagnosis. A median of 2.5 times various percutaneous radiological interventional procedures were performed in eight patients prior to AVG migration diagnosis. The site of migration was the duodenum in eight patients, gastric antrum in four, and Roux limb in the remaining one patient. The migrated AVS were made of polytetrafluoroethylene (PTFE) in 10 patients and polyethylene terephthalate (Dacron) in three. The migrated AVGs were endoscopically removed in seven patients and surgically removed in six. Only one patient died due to sepsis unrelated to AVG migration. CONCLUSION: AVG migration into the adjacent hollow viscus following right lobe LDLT is a rare and serious complication. Repetitive ERCP, interventional radiological procedures, infection related to biliary leakage, and thrombosis of AVGs are among the possible risk factors.

RESUMO

Reconstruction of anomalous portal vein branching (APVB) during right lobe living donor liver transplantation (LDLT) can be challenging. The goal of this article is to describe our surgical technique, named the Malatya Approach, in case of APVB during right lobe LDLT. The technique unifies the APVB and obtains a funnel-shaped common extension with a circumferential fence by a saphenous vein conduit. In total, 126 (10.6%) of 1192 right lobe grafts had APVB that were divided into 2 groups according to the adopted surgical techniques: the Malatya Approach group (n = 91) and the previously defined other techniques group (n = 35). Both groups were compared regarding portal vein thrombosis (PVT), postoperative 90-day mortality and survival. PVT developed in 3 patients (3.3%) in the Malatya Approach group and developed in 10 (28.6%) patients for the other group (P < 0.001). There were 8 (8.8%) 90-day mortalities in the Malatya Approach group (1 PVT related) and 15 patients (9 PVT related) died in the other techniques group (P < 0.001). Mean follow-up time for both groups was similar (999.1 days for the Malatya Approach group versus 1024.7 days for the other group; P = 0.47), but longterm survival in the Malatya Approach group was better than in the other group (84.6% versus 40%; P < 0.001). Multivariate analysis revealed that the Malatya Approach group showed less PVT development and longer survival (P < 0.001). This technique is promising to avoid PVT and mortalities in cases of APVB during right lobe LDLT. Liver Transplantation 23 751-761 2017 AASLD.

RESUMO

 Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer and the third leading cause of cancer related death worldwide. In recent years, the prevalence of HCC has increased in both developing and developed countries. Most HCC cases develop in the presence of advanced chronic liver disease related to viral hepatitis. In particular hepatitis B virus and hepatitis C virus infections are considered as major HCC risk factors worldwide. However, current studies provide strong evidence for increasing numbers of HCC in nonalcoholic fatty liver disease (NAFLD). NAFLD represents the hepatic manifestation of metabolic syndrome which is based on obesity and insulin resistance. Epidemiologic data clearly demonstrates that NAFLD and obesity-related disorders are significant risk factors for tumor development in general and HCC in particular. As a consequence of life style changes towards higher calorie intake and less exercise, obesity and metabolic syndrome are spreading all over the world. Due to this increase in obesity and metabolic syndrome NAFLD-related HCC will become a major health care problem in the future. In conclusion, better understanding of the impact of NAFLD and obesity in the development of HCC will improve our treatment strategies of HCC and allow preventive measures.

RESUMO

BACKGROUND: To investigate the potential protective antioxidant role of ursodeoxycholic acid (UDCA), melatonin, and allopurinol treatment in cyclosporine (CsA)-induced hepatotoxicity. METHODS: Hepatotoxicity was established in Sprague-Dawley rats by daily administration of CsA. Treatment groups were additionally administered UDCA, melatonin, or allopurinol treatments. Rats that received no CsA and no treatments served as a control group. Liver samples from each group were examined by histopathologic analysis to determine the effects of CsA treatment on liver morphology. Biochemical assays were also used to determine the effect of CsA treatment on liver function, in the presence or absence of UDCA, melatonin, or allopurinol. RESULTS: CsA treatment induced hepatotoxicity, resulting in sinusoidal dilatation, congestion, infiltration, hydropic degeneration, and loss of glycogen storage in the liver. From a molecular perspective, the CsA treatment increased levels of malondialdehyde (MDA) levels, decreased levels of reduced glutathione and xanthine oxidase, and decreased activities of superoxide dismutase and catalase. The CsA treatment also resulted in decreased serum total antioxidant capacity, whereas alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin levels, and total oxidant status were increased. Treatment with UDCA, melatonin, or allopurinol reduced the CsA-induced histopathologic changes, as compared with CsA-treated samples. In addition, UDCA, melatonin, or allopurinol treatment mitigated the CsA-induced effects on glutathione and MDA levels, and on superoxide dismutase and catalase activities, as well as reduced the CsA-mediated perturbations in serum levels of total antioxidant capacity, total oxidant status, and alkaline phosphatase. CONCLUSIONS: UDCA, allopurinol, and melatonin may each help to protect against CsA-induced damage to liver tissues, possibly through effects on the antioxidant system.

RESUMO

OBJECTIVE: Thyroid pathologies and non-medullary thyroid cancer often accompany primary hyperparathyroidism (PHPT). The purpose of this study was to examine the association between thyroid diseases, especially micropapillary thyroid cancer, with PHPT. MATERIAL AND METHODS: Data regarding 46 patients who were operated on with a diagnosis of PHPT at Inonu University Faculty of Medicine, General Surgery Clinic between June 2009 and March 2013 were retrospectively analyzed. Age, gender, levels of preoperative calcium, parathyroid hormone and phosphorus, and the histopathological results of the removed parathyroid and thyroid tissues were evaluated. All of the patients had a preoperative diagnosis of PHPT and there was no history of radiation to the head and neck region in any of the patients. RESULTS: Out of the 46 patients who were operated on for PHPT, 39 were female and 7 were male. The mean age was 52.8 years (25-76). Simultaneous thyroidectomy was performed in 35 patients (76.1%) due to an accompanying thyroid disorder. Papillary microcarcinoma was detected in 5 of these 35 (10.9%) patients who underwent thyroidectomy, two of which (40%) were multifocal tumors. The benign thyroid pathologies detected in the remaining 30 (65.2%) cases included lymphocytic thyroiditis in 3, Hashimoto thyroiditis in 1, follicular adenoma in 3 (two of which was Hurtle cell), and nodular colloidal goiter in 23 patients. The preoperative serum phosphate level was significantly higher in the group with papillary thyroid microcarcinoma (p=0.013). CONCLUSION: In regions where goiter is endemic, thyroid diseases and thyroid papillary microcarcinoma occur in association with PHPT at a higher rate compared to the normal population. Therefore, we believe that patients who are planned for surgery due to PHPT should be thoroughly investigated for the presence of any concomitant malignant thyroid pathologies in the preoperative period. It should also be kept in mind that patients with high blood serum phosphate values may have an increased risk of papillary thyroid microcarcinoma.

RESUMO

BACKGROUND: This study aimed to determine the clinical and demographic features of acute amebic appendicitis by reviewing the reported cases. METHODS: The PubMed and MEDLINE databases were searched to identify articles related to amebic appendicitis using key words. The search included all articles published between 1935 and 2012 without restricting language, journal, or country. RESULTS: A total of 174 cases of amebic appendicitis reported in 42 articles were analyzed. The mean age of the patients was 23.5 years (range 2 months-83 years). The majority of patients were male (74.0 %), and the majority of cases were reported from countries with high/moderate risk for amebiasis (76.5 %). A history of traveling to a high/moderate-risk country was cited in 64.0 % of the overall cases. The interval between travel and onset of clinical symptoms ranged from months to years. History of or coexisting dysenteric diarrhea was present in only 7.0 and 14.0 % of overall cases, respectively. A preoperative diagnosis of amebiasis was cited for only five cases (3.0 %). Complicated appendicitis was present in 30.7 % of cases, some of which required colon resection. Severe postoperative intraabdominal complications (e.g., liver abscess, abdominal sepsis, gastrointestinal fistula, hemorrhage) occurred in 19.4 % of surgery-treated patients. The overall mortality rate was 3.2 %. CONCLUSION: Appendectomy specimens should be routinely sent for histopathologic examination. In the case of suspected amebic acute appendicitis, extra precautions-early appendectomy, metronidazole for antibiotic prophylaxis, wet-preparation examination, obtaining a timely pathology result, increasing the awareness of uncommon complications of appendectomy-can hasten appropriate therapeutic intervention and improve outcome.

RESUMO

BACKGROUND: We aimed to evaluate the clinical characteristics and outcomes of mild-severe COVID-19 pneumonia cases in liver transplant (LT) recipients. METHODS: Ten LT recipients diagnosed as having COVID-19 pneumonia in a 6-month period in our transplantation center were included. Demographic and medical data of the recipients were retrospectively collected; clinical courses, treatment responses, and outcomes were evaluated. RESULTS: Ten LT recipients were male, had a median age of 57 years (min-max, 36-69 years; interquartile range [IQR], 13 years), and had right lobe from living donor LT performed in a median of 11 months (min-max, 1-72 months; IQR, 12 months). Five patients had severe pneumonia, and the remaining patients had mild/moderate pneumonia. The most frequent symptoms were fever (90%) and cough (70%). Favipiravir, enoxaparin sodium, and corticosteroid were initiated at the time of the diagnosis; immunosuppressive drug doses were reduced or discontinued in 3 cases. Lymphopenia median: 510/mL (min-max, 90-1400 mL; IQR, 610 mL), increased levels of C-reactive protein median: 4.72 (min-max, 0.31-23.4; IQR, 8.5), and ferritin median: 641 (min-max, 40 to ≥ 1650; IQR, 1108) were frequent. Four patients required antibacterial treatments because of emerging bacterial pneumonia and/or sepsis. All patients were hospitalized for a median of 10 days. One patient with sepsis died on the 26th day after intensive care unit admission, and the remaining 9 survived. No further complication was recorded for 1-month follow-up. CONCLUSIONS: Commencing favipiravir, enoxaparin sodium, and corticosteroid treatments; close follow-up of the developing complications; the temporary reduction or cessation of immunosuppression; a multidisciplinary approach; early awareness of the bacterial infections; and the initiation appropriate antibiotic treatments can contribute to success.

RESUMO

Hepatocellular carcinoma (HCC) is a highly malignant disease and early diagnosis rates remain to be unsatisfactory. Owing to this limitation, advances in treatment options including liver transplantation (LT) are limited to improve survival. Recent HCC guidelines no longer recommend alpha-fetoprotein (AFP) as a surveillance and diagnostic tool for HCC. Hence, utilization of novel biomarkers has become imperative to improve disease management strategies. Noninvasive, serum-based biomarkers are potential options to aid early diagnosis as well as prompting treatment. However, further studies are required to find out the accuracy and potential of these approaches and introduce into clinical practice.

RESUMO

PURPOSE: Our aim was to investigate the psychosocial outcomes of the donors whose recipients died after living donor liver transplantation (LDLT). METHODS: Forty-one donors whose recipients died and 87 donors whose recipients were alive after LDLT at Inonu University Liver Transplantation Institute between 2012 and 2017 were included into the study. Demographic data form, Beck anxiety scale, Beck depression scale, Beck Hopelessness Scale, Posttraumatic Growth Inventory, Decision Regret Scale, Multidimensional Scale of Perceived Social Support, and general evaluation questionnaire (24 questions) were used in all donors by face to face questioning. In addition to the descriptive statistical analysis, chi-square and student's t tests were used to evaluate the differences between the groups. RESULTS: Recipient death after living donor liver transplantation is a factor that negatively increases the level of anxiety, depression, hopelessness levels, and repentance of donors, and adversely affects the psychological growth of the donors after donation experience. CONCLUSION: Regular follow-up of the donors should be done psychosocially in the postoperative period, especially the donors whose recipients have died should be followed up more frequently, and their support and treatment should be provided when needed. The donors should also be informed about the psychosocial implications of operative management and postoperative period. More studies are needed regarding the psychosocial problems of the donors.

RESUMO

Survival was examined from a Turkish liver transplant center of patients with HCC, to identify prognostic factors. Data from 215 patients who underwent predominantly live donor liver transplant for HCC at our institute over 12 years were included in the study and prospectively recorded. They were 152 patients within and 63 patients beyond Milan criteria. Patients beyond Milan criteria were divided into two groups according to presence or absence of tumor recurrence. Recurrence-associated factors were analyzed. These factors were then applied to the total cohort for survival analysis. We identified four factors, using multivariate analysis, that were significantly associated with tumor recurrence. These were maximum tumor diameter, degree of tumor differentiation, and serum AFP and GGT levels. A model that included all four of these factors was constructed, the 'Malatya criteria.' Using these Malatya criteria, we estimated DFS and cumulative survival, for patients within and beyond these criteria, and found statistically significant differences with improved survival in patients within Malatya criteria of 1, 5, and 10-year overall survival rates of 90.1%, 79.7%, and 72.8% respectively, which compared favorably with other extra-Milan extended criteria. Survival of our patients within the newly defined Malatya criteria compared favorably with other extra-Milan extended criteria and highlight the usefulness of serum AFP and GGT levels in decision-making.

RESUMO

CONTEXT: A solid pseudopapillary tumor of the pancreas is a rare neoplasm which, for the most part, affects young women and has a relatively favorable prognosis with a low malignant potential. These tumors usually have unclear clinical features and may form very large masses before being diagnosed. CASE REPORT: We report the case of a 29-year-old woman who underwent complete resection of the tumor using a distal pancreatectomy and splenectomy procedure. The patient is being followed-up and in good condition. A review of the relevant literature is also presented. CONCLUSIONS: A solid pseudopapillary tumor of the pancreas is a rare condition with a low potential for malignancy and favorable prognosis; surgical resection is generally curative.

RESUMO

OBJECTIVES: In irreversible acute liver failure, liver transplant is the only viable treatment option. In this study, our aim was to evaluate and determine the factors related to mortality in patients who received liver transplants in accordance with King's College criteria for acute liver failure in order to prevent futile operations. MATERIALS AND METHODS: Our study included 65 adult patients with acute liver failure who received liver transplant according to King's College criteria. Factors related to mortality, including demographic and operative data, causes of acute liver failure, severity of encephalopathy, and laboratory data, were retrospectively analyzed. Patients who received living-donor liver grafts had donations from first-degree to fourth-degree relatives. RESULTS: Of 65 patients analyzed, 55.3% were women. Ninety-day mortality rate was 36.9%. Preoperative bilirubin levels in survivor and nonsurvivor groups were 16.3 ± 9.6 and 21.3 ± 10.7 mg/dL, respectively (P = .03). Mortality rates of patients with bilirubin above and below 9 mg/dL were 31.8% and 8.3%, respectively (P = .03). Of patients who died, 75% were women (significantly more women than men, P = .015). Patients who had deceased-donor liver transplants had a significantly higher mortality rate than those who had living-donor liver transplants (52% vs 27.5% ; P = .046). At 3 days posttransplant, bilirubin, creatinine, aspartate aminotransferase, phosphorus, sodium, and ammonia levels were significantly different between survivor and nonsurvivor groups (P < .05). CONCLUSIONS: We found living-donor liver transplant to be superior versus deceased-donor liver transplant with regard to development of acute liver failure. Reasons could include the long wait period for deceased donors and liver grafts coming from marginal donors. Bilirubin level and presence of grade 4 encephalopathy had predictive values for poor prognosis of patients.

RESUMO

OBJECTIVE: To evaluate the histopathologic effects of L-carnitine (LC) in an experimental severe pancreatitis (SP) model induced with sodium taurocholate (STC). SUMMARY OF BACKGROUND DATA: LC is an amino acid-like molecule that plays an active role in transporting fatty acids and producing Acetyl CoA in mitochondrial matrix for ß-oxidation to provide energy which is needed for metabolism. It has ameliorative effects on cell injury demonstrated in many studies. The present study focuses on evaluating histopathologic effects of LC in an experimental SP model. METHODS: This experimental study in rats was conducted at the Experimental Animal Research Laboratory of the Faculty of Medicine of Inonu University, Malatya, Turkey. Thirty-two Spraque-dawley male rats were divided into 4 groups in a randomized fashion: control (C) group, L-carnitine (LC) group, pancreatitis (P) group, pancreatitis and L-carnitine (P+LC) group. Pancreatitis was induced by a retrograde pancreatic duct injection of 4% sodium taurocholate and L-carnitine was administered 200 mg/kg/day in treatment group. Rats were euthanized with cardiac puncture under anesthesia at 48th hour of the experiment for biochemical and histopathological examination. RESULTS: In (P+LC) group, the histopathological findings of the pancreatitis were markedly reduced. Acinar cell degeneration was rarely seen. Interlobular and intralobular inflammation and edema was generally mild. The pancreatic damage score of (P+LC) group was significantly lower than that of the (P) group (p<0.05). CONCLUSION: This study revealed that l-carnitine has a significant histopathologic protective effect on acinar cell degeneration in STC-induced SP model in rats.

To provide an overview of the medical literature on giant splenic artery aneurysm (SAA).The PubMed, Medline, Google Scholar, and Google databases were searched using keywords to identify articles related to SAA. Keywords used were splenic artery aneurysm, giant splenic artery aneuryms, huge splenic artery aneurysm, splenic artery aneurysm rupture, and visceral artery aneurysm. SAAs with a diameter ≥5 cm are considered as giant and included in this study. The language of the publication was not a limitation criterion, and publications dated before January 15, 2015 were considered.The literature review included 69 papers (62 fulltext, 6 abstract, 1 nonavailable) on giant SAA. A sum of 78 patients (50 males, 28 females) involved in the study with an age range of 27-87 years (mean ± SD: 55.8 ±â€Š14.0 years). Age range for male was 30-87 (mean ±â€ŠSD: 57.5 ±â€Š12.0 years) and for female was 27-84 (mean ±â€ŠSD: 52.7 ±â€Š16.6 years). Most frequent predisposing factors were acute or chronic pancreatitis, atherosclerosis, hypertension, and cirrhosis. Aneurysm dimensions were obtained for 77 patients with a range of 50-300 mm (mean ±â€ŠSD: 97.1 ±â€Š46.0 mm). Aneurysm dimension range for females was 50-210 mm (mean ±â€ŠSD: 97.5 ±â€Š40.2 mm) and for males was 50-300 mm (mean ±â€ŠSD: 96.9 ±â€Š48.9 mm). Intraperitoneal/retroperitoneal rupture was present in 15, among which with a lesion dimension range of 50-180 mm (mean ±â€ŠSD; 100 ±â€Š49.3 mm) which was range of 50-300 mm (mean ±â€ŠSD: 96.3 ±â€Š45.2 mm) in cases without rupture. Mortality for rupture patients was 33.3%. Other frequent complications were gastrosplenic fistula (n = 3), colosplenic fistula (n = 1), pancreatic fistula (n = 1), splenic arteriovenous fistula (n = 3), and portosplenic fistula (n = 1). Eight of the patients died in early postoperative period while 67 survived. Survival status of the remaining 3 patients is unclear. Range of follow-up period for the surviving patients varies from 3 weeks to 42 months.Either rupture or fistulization into hollow organs risk increase in compliance with aneurysm diameter. Mortality is significantly high in rupture cases. Patients with an evident risk should undergo either surgical or interventional radiological treatment without delay.

RESUMO

INTRODUCTION: Liver transplantation is one of the best treatment options for end-stage liver disease. In Turkey, living donor liver transplantation (LDLT) is performed more frequently than cadaveric transplantation, because organ donation is unpopular in our country. Neurological complications contribute to poor postoperative outcomes after liver transplantation. In the present study, we aimed to evaluate the outcomes of LDLT patients in whom such complications developed early during postoperative follow-up in the intensive care unit. METHODS: Of 217 LDLTs performed between August 2011 and August 2012, neurology consultations were arranged for 29 patients (13.36%) because of development of new-onset neurological symptoms and/or findings in patients with neurologically uneventful preoperative histories. We retrospectively collected data on age, gender, primary disease, Model for End-Stage Liver Disease (MELD) score, and postoperative hospitalization duration of those who survived. The indications for neurological consultation and diagnoses were categorized into acute confusion/encephalopathy, epileptic seizures, leukoencephalopathy, and focal neurological deficits. The immunosuppressive treatment regimens prescribed were also considered. The outcomes of the 2 groups (with and without neurological complications) were compared. RESULTS: The mean patient age was 44.52±16.24 years, and males predominated (65.5%, n=19). Acute confusion/encephalopathy was the most frequent complication (62.1%, n=18), followed by epileptic seizures (27.6%, n=8), cerebrovascular disease (6.9%, n=2), and leukoencephalopathy (3.4%, n=1). Statistically significant between-group differences in age (44.5±16.2 vs. 34.33±20.98 years; p<0.001), and proportions of patients with a disease of viral etiology (55.17% vs. 35.63%, p<0.05), were evident. Mortality was significantly higher in the group with neurological complications (65.5% vs. 37.32%, p<0.05). The duration of postoperative hospitalization was also significantly longer in this group (29.80±15.04 vs. 10.00±5.47 days; p<0.05). CONCLUSION: Mortality was significantly higher and the duration of postoperative hospitalization significantly longer in LDLT patients with new-onset neurological complications than in those without such complications.

RESUMO

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.
