RESUMO

INTRODUCTION: Liver transplantation offers the most reasonable expectation for curative treatment for hepatocellular carcinoma. Living-donor liver transplantation represents a treatment option, even in patients with extended Milan criteria. This study aimed to evaluate the outcomes of hepatocellular carcinoma patients, particularly those extended Milan criteria. MATERIALS AND PATIENTS: All HCC patients who received liver transplant for HCC were included in this retrospective study. Clinical characteristics including perioperative data and survival data (graft and patient) were extracted from records. Univariate and multivariate analyses was performed to identify significant prognostic factors for survival, postoperative complications and recurrence. RESULTS: Two-hundred and two patients were included. The median age was 54.8 years (IQR 53-61). Fifty-one patients (25.3%) underwent deceased donors liver transplantation and 151 patients (74.7%) underwent living donor liver transplantation. Perioperative mortality rate was 5.9% (12 patients). Recurrent disease occurred in 43 patients (21.2%). The overall 1-year and 5-year survival rates were 90.7% and 75.6%, respectively. Significant differences between patients beyond Milan criteria compared to those within Milan criteria were not found. Alpha-fetoprotein level >300 ng/mL, vascular invasion, and bilobar tumor lesions were independent negative prognostic factors for survival. CONCLUSION: Liver transplantation is the preferred treatment for hepatocellular carcinoma and it has demonstrated an excellent potential to cure even in patients with beyond Milan criteria. This study shows that the Milan criteria alone are not sufficient to predict survival after transplantation. The independent parameters for survival prediction are Alpha-Fetoprotein-value and status of vascular invasion.

RESUMO

Hepatocellular carcinoma, intrahepatic cholangiocarcinoma, and combined hepatocellular and cholangiocarcinoma are the most common cancers of the liver. In this study, our first aim is to evaluate the relationship between prognosis and clinicopathological parameters. The second aim involves investigating the need for immunohistochemical staining and patterns of tumours to differentiate between them. Sixty-one cases were included in this study. For IHC, we used Hep par-1, CK7, CK19, CD56 and p53 staining, and the patterns of tumours were evaluated in haematoyxylin-eosin sections. No significant differences were found in Kaplan-Meier life analysis between the tumour types and OS and DFS values, but these values were greater in HCC than in ICC. There were no relationships between clinicopathologic parameters and OS and DFS. Although the multifocality, stage and grade of tumour were higher in HCC than in ICC, the perineural invasion and lymph node metastasis were more common in ICC than in HCC. The diagnosis was changed in 4 cases, from HCC to ICC in one case and to combined type in 3 cases after IHC. Pathologist should be alert to mixed patterns in terms of diagnosis and IHC, because it helps differential diagnosis in these cases.

RESUMO

The graft-to-recipient weight ratio (GRWR) is an important selection criterion for living donor liver transplantation (LDLT). The generally accepted threshold is known to be 0.8%. We believe that this threshold can be reduced under certain conditions. The aim of this study was to evaluate the results of these patients with GRWR < 0.8%. Between 2004 and 2015, 649 patients underwent right lobe LDLT for end-stage liver disease in adult patients. All recipients who had GRWR < 0.8% were identified. The data of these patients were retrospectively analyzed and compared to patients with GRWR ≥ 0.8%. There were 43 patients with GRWR < 0.8%. Out of these patients, 7 (16%) had GRWR of 0.6%. The median Model for End-Stage Liver Disease (MELD) score was 15, and the median donor age was 30 years. Anterior segment drainage was ensured. Portal inflow modulation was performed by splenic artery ligation according to the portal flow. Postoperative complications were seen in 6 (14%) patients. Of all 43 patients, 3 (7%) died perioperatively within 1 month, and 1 (2%) patient underwent retransplantation due to graft failure. The mean hospital stay was 18 days. The 1-year survival rate was 93%. None of the patients had a laboratory MELD score above 20. The comparison of the results with the patients who had GRWR ≥ 0.8% has shown no significant difference, except MELD score, body mass index (BMI), and rate of anterior segment drainage. The GRWR can be decreased even to 0.6% if the MELD score is below 20, donor age is below 45 years, and there are no signs for any hepatosteatosis of the donor graft. In these patients, it is essential that the anterior segment drainage is secured and the portal inflow modulation is performed according to the portal flow.

RESUMO

FH is an autosomal dominant genetic disorder characterized by increased TC and LDL level, which leads to xanthomas, atherosclerosis, and cardiac complications even in childhood. The treatment options are diet, medical treatment, lipid apheresis, and LT. The aim of our study was to analyze our data of patients with FH. Between 2004 and 2015, there were 51 patients who underwent pediatric LT at our center. All patients with FH were identified, and the data were retrospectively analyzed. There were eight patients with homozygous FH in the median age of 10 years (IQR 6-12) who underwent LT. The median pre-operative TC and LDL levels were 611 mg/dL (IQR: 460-844) and 574 mg/dL (IQR: 398-728) and decreased to normal levels 1 week after LT (TC: 193 mg/dL and LDL: 141 mg/dL). Two patients died two and 18 months after LT due to sudden cardiac arrest. Both patients were diagnosed with cardiovascular disease pre-operatively. The LT is the only curative treatment for this disease. To achieve an excellent outcome, it should be performed before the development of cardiovascular disease, because the regression of severe cardiovascular disease after transplantation is limited.

RESUMO

Echinococcus alveolaris is a parasite from tenia family which causes tumor-like lesions in the livers of infected people. If it is not diagnosed in the early stage of the disease, it frequently causes multiple cysts in the liver. The clinical importance of the disease is rapid progression, infiltration into different tissues like a malignant tumor and capacity of creating metastatic masses. The disease could be treated either by surgical resection or liver transplantation. The resection of the cystic disease is the preferred treatment method. In cases where resection is not possible, liver transplantation is the choice of treatment. Here we present three cases which were admitted to the hospital with unresectable hepatic alveolar echinococcosis and treated by liver transplantation successfully. Patients for whom surgical resection is not possible, we recommend liver transplantation as the treatment method.

RESUMO

BACKGROUND: The right lobe of the liver is generally preferred for living donor liver transplantation in adult patients with end-stage liver disease. It is important to know the preoperative factors relating to the major postoperative complications. We therefore evaluated the possible risk factors for predicting postoperative complications in right lobe liver donors. METHODS: Data from 378 donors who had undergone right lobe hepatectomy at our center were evaluated retrospectively. The factors we evaluated included donor age, gender, body mass index (BMI), remnant liver volume, operation time, history of previous abdominal surgery, inclusion of the middle hepatic vein and variations in the portal and bile systems. RESULTS: Of the 378 donors, 219 were male and 159 female. None of the donors died, but 124 (32.8%) donors experienced complications including major complications (Clavien scores III and IV) in 27 (7.1%). Univariate analysis showed that complications were significantly associated with male gender and higher BMI (P<0.05), but not with donor age, remnant liver volume, operation time, graft with middle hepatic vein, variations in the portal and bile systems and previous abdominal surgery (P<0.05). Multivariate logistic regression analysis showed that major complications were significantly associated with male gender (P=0.005) and higher BMI (P=0.029). Moreover, the Chi-square test showed that there were significant relationships between major complications and male gender (P=0.010, X2=6.614, df=1) and BMI >25 kg/m2 (P=0.031, X2=8.562, df=1). Of the 96 male donors with BMI >25 kg/m2, 14 (14.6%) with major complications had significantly smaller mean remnant liver volume than those (82, 85.4%) without major complications (32.50%+/-4.45% vs 34.63%+/-3.11%, P=0.029). CONCLUSION: Male donors with BMI >25 kg/m2 and a remnant liver volume ≤32.50% had a significantly increased risk for major complications.

RESUMO

Living donor liver transplantation (LDLT) is an accepted option for end-stage liver disease, particularly in countries in which there are organ shortages. However, little is known about LDLT for obese patients. We sought to determine the effects of obesity on pretransplant living donor selection for obese recipients and their outcomes. On the basis of body mass index (BMI) values, 148 patients were classified as normal weight (N), 148 were classified as overweight (OW), and 74 were classified as obese (O). O recipients had significantly greater BMI values (32.1 ± 1.6 versus 23.2 ± 1.9 kg/m(2), P < 0.001) and received larger actual grafts (918.9 ± 173 versus 839.4 ± 162 g, P = 0.002) than recipients with normal BMI values. Donors who donated to O recipients had a greater mean BMI (26.3 ± 3.8 kg/m(2)) than those who donated to N recipients (24.4 ± 3.2 kg/m(2), P = 0.001). Although O recipients were more likely to face some challenges in finding a suitable living donor, there were no differences in graft survival [hazard ratio (HR) = 0.955, 95% confidence interval (CI) = 0.474-1.924, P = 0.90] or recipient survival (HR = 0.90, 95% CI = 0.56-1.5, P = 0.67) between the 3 groups according to an adjusted Cox proportional hazards model. There were no significant differences in posttransplant complication rates between the 3 recipient groups or in the morbidity rates for the donors who donated to O recipients versus the donors who donated to OW and N recipients (P = 0.26). Therefore, we recommend that obese patients undergo pretransplant evaluations. If they are adequately evaluated and selected, they should be considered for LDLT.

RESUMO

BACKGROUND: We aimed to study the predictive value of preoperative perform [18F] Fludeoxyglucose positron emission tomography-computed tomography ([18] FDG PET-CT) for survival in liver transplantation due to hepatocellular cancer. METHODS: Ninety-six patients who underwent liver transplantation for hepatocellular cancer (HCC) after preoperative PET-CT evaluation were examined for the study. All patients' ages, genders, body mass index, blood groups, Child-Pugh and Model for End-Stage Liver Disease scores, etiologies, median Alpha Fetoprotein values, Milan Criteria and T stages, grades, macrovascular and microvascular invasions, multicentricities, maximum and total tumor sizes, tumor number findings in explant specimens, and recurrence rates were analyzed statistically. RESULTS: Statistically, microvascular (P = .002) and macrovascular invasions (P = .034) were observed more frequently in patients who are PET-CT (+) compared with patients who are PET-CT (-). PET-CT positivity was associated with shortened disease-free survival (DFS) statistically (P = .004). CONCLUSION: Positron emission tomography-CT positivity may be important for predicting prognostic markers such as DFS and vascular invasion in the preoperative evaluation. Before transplantation, PET-CT should be applied to all patients with HCC.

RESUMO

In right lobe (RL) living donor liver transplantation (LDLT), portal vein (PV) variations are of immense clinical significance. In this study, we describe in detail our PV reconstruction techniques in RL grafts with variant PV anatomy and evaluate the impact of accompanying biliary variations on the recipient outcomes. In a total of 386 RL LDLTs performed between July 2004 and July 2012, the clinical data on 52 (13%) transplants using RL grafts with variant PV anatomy were retrospectively analyzed. Portal vein anatomy was classified as type 2 in 20 patients, type 3 in 24 patients, and type 4 in eight patients. The PV reconstruction techniques utilized included back-wall plasty (n = 21), back-wall plasty with saphenous vein graft interposition (n = 6), saphenous vein graft interposition (n = 5), cryopreserved iliac vein Y-graft interposition (n = 6), and quiltplasty (n = 3). There was no donor mortality. In a median follow-up of 29 months, none of the recipients had vascular complications. Anomalous PV anatomy was associated with a high (54%) incidence of biliary variations; however, these variations did not result in increased biliary complication rate. Overall, the 1- and 3-year patient survival rates of recipients were 91% and 81%, respectively. Vascular and biliary variations in RL grafts render LDLT technically more challenging. By employing appropriate reconstruction techniques, it is possible to successfully use RL grafts with PV variations without endangering recipient and donor safety.

RESUMO

OBJECTIVE: Factor 2 and Factor 5 mutations are among the most common procoagulant genetic disorders and are routinely evaluated in donor preparation. Homozygous mutations are contraindicated for surgery, but heterozygous mutations cannot be said to be an impediment. We aimed to investigate the effect of heterozygous gene mutation of F2 and/or F5 on complications. METHODS: In our study, 210 living liver donors were examined. The available data of Factor 2 and 5 heterozygous positive donors were evaluated in terms of 21 donor patients and 30 liver recipients. The heterozygous positive group and the control group were statistically compared in terms of age, gender, length of hospital stay, post-operative deep vein thrombosis, pulmonary embolism, portal vein thrombosis, bile duct stenosis and bile leakage complications, lung infection and atelectasis, and wound infection. In addition, these patients were statistically compared in terms of laboratory tests. In addition, complications in recipients implanted with mutant grafts were evaluated statistically and numerically. RESULTS: Hospital staying was longer statistically in the donor group with heterozygous mutations than in the control group. Hemoglobin and albumin blood levels were lower (p=0.031, p=0.016); INR and ALT levels were higher (p=0.005, p=0.047) statistically in the control group than in the donor group with heterozygous mutations. There was no statistically significant difference between heterozygous mutant groups in terms of biliary tract complications and hepatic vessel thrombosis in recipients. CONCLUSION: Considering the longer hospital stay in the presence of these mutations, the increased need for treatment in this process and the close follow-up of liver functions should be considered.

RESUMO

Background and Aim: Combined hepatocellular-cholangiocarcinoma (CHC) requires attention clinically and pathologically after liver transplantation (LT) because of its unique biology, difficulties in diagnosis, and being rare. We aimed to present our single-center experience for this incidental combined tumor. It is aimed to present our single-center experience for this incidental combined tumor. Materials and Methods: Seventeen patients with CHC were included in the study. There were 260 hepatocellular carcinoma (HCC) patients determined as the control group. Patients were evaluated for demographic, etiological, pathological features, and survival. Results: Macrovascular and microvascular invasion levels were significantly higher in the CHC group (p<0.05). P53, CK19, and CK7 levels were significantly higher in the CHC group (p<0.05). Hepatocyte-specific antigen level was significantly higher in the HCC group. The mean overall survival was significantly higher in the HCC group (p<0.05). Conclusion: Even though CHC is a rare liver tumor, it has features that need to be clarified regarding both survival and tumor biology. Investigating prognostic factors, especially in terms of survival and recurrence, will be very beneficial to identify candidates who will benefit from LT and be included in the indications for LT for CHC. This study evaluated the outcomes of patients showing combined HCC-intrahepatic cholangiocarcinoma in explant pathology.

RESUMO

Hepatorenal syndrome is defined as renal failure caused by acute or chronic liver failure without any laboratory or histological reasons. The exact etiology of this syndrome is unknown. However, vasodilatation in the splanchnic area as a result of cirrhosis and portal hypertension, reflex systemic and splanchnic vasoconstriction are the basic pathophysiological reasons of this syndrome. The decrease of renal perfusion, decrease in glomerular filtration rate, sodium retention and deterioration of excretion of free water are the major renal problems and these remain progressive according to the stage of liver disease. The treatment of this syndrome is correction of the underlying problem. Here, we report a patient who was having hemodialysis due to renal failure as a consequence of liver cirrhosis for three months and returned back to his normal life without a need for dialysis after liver transplantation.

RESUMO

Thrombosis of recipient hepatic artery is a life threatening complication for liver transplantation. The etiology of hepatic arterial thrombosis is multi-factorial and can be caused by intimal dissection, poor surgical technique and coagulopathies. The patency of hepatic arterial flow is very important for both graft survival and patient survival. Intraoperative diagnosis of inadequate hepatic arterial flow found with Doppler ultrasonography is essential in order to achieve good results after liver transplantation. Urgent re-anastomosis is necessary when the arterial blood flow is insufficient. We performed 317 living donor liver transplantations from July 2004 to July 2011. We used recipient splenic artery for hepatic artery reconstruction in six patients. These six patients were included in this study. Using the recipient splenic artery is a simple, safe and practical alternative for hepatic artery re-anastomosis in living donor liver transplantations.

RESUMO

Living donor liver right lobe transplantation using donors with variation of the right sectorial portal vein is considered a challenging procedure in terms of the donor's safety and the complexity of reconstruction in the recipient. We describe an innovative technique to reconstruct double portal vein orifices via a deceased donor iliac vein graft. The postoperative course of the recipient was uneventful. Doppler ultrasound on the fourth postoperative month revealed equivalent flow in both portal vein branches. Reconstruction of double right portal vein branches using a cryopreserved iliac vein is a valuable technique for utilizing right lobe grafts with challenging portal vein anatomy.

RESUMO

BACKGROUND: In liver transplantation or resection for hepatocellular carcinoma (HCC), patient selection depends on morphological features. In patients with HCC, we performed a clinicopathological analysis of risk factors that affected survival after liver transplantation. METHODS: In 389 liver transplantations performed from 2004 to 2010, 102 were for HCC patients. Data were collected retrospectively from the Organ Transplantation Center Database. Variables were as follows: age, gender, preoperative alpha-fetoprotein (AFP) levels, Child-Pugh and MELD scores, prognostic staging criteria (Milan and UCSF), etiology, number of tumors, the largest tumor size, total tumor size, multifocality, intrahepatic portal vein tumor thrombosis, bilobarity, and histological differentiation. RESULTS: One hundred and two patients were evaluated. The 5-year overall survival rate was 56.5%. According to the UCSF criteria, 63% of the patients were within and 37% were beyond UCSF (P=0.03). Ten patients were excluded (one with fibrolamellary HCC and 9 because of early postoperative death without HCC recurrence), and 92 patients were assessed. The mean age of the patients was 56.5+/-6.9 years. Sixty-two patients underwent living donor liver transplantations. The mean follow-up time was 29.4+/-22.6 months. Fifteen patients (16.3%) died in the follow-up period due to HCC recurrence. Univariate analysis showed that AFP level, intrahepatic portal vein tumor thrombosis, histologic differentiation and UCSF criteria were significant factors related to survival and tumor recurrence.The 5-year estimated overall survival rate was 62.2% in all patients. According to the UCSF criteria, and the 5-year overall survival rate was 66.7% within and 52.7% beyond the criteria (P=0.04). Multivariate analysis showed that AFP level and poor differentiation were independent factors. CONCLUSIONS: For proper patient selection in liver transplantation for HCC, prognostic criteria related to tumor biology (especially AFP level and histological differentiation) should be considered. Poor differentiation and higher AFP levels are indicators of poor prognosis after liver transplantation.

RESUMO

BACKGROUND: Biliary complications that developed after right lobe liver transplantation from living donors were studied in a single centre. METHODS: From 2004 to 2010, 200 consecutive living donor right lobe liver transplantations were performed. The database was evaluated retrospectively. Biliary complications were diagnosed according to clinical, biochemical and radiological tests. The number of biliary ducts in the transplanted graft, the surgical techniques used for anastomosis, biliary strictures and bile leakage rates were analysed. RESULTS: Of a total of 200 grafts, 117 invloved a single bile duct, 77 had two bile ducts and in six grafts there were three bile ducts. In 166 transplants, the anastomosis was performed as a single duct to duct, in 21 transplants double duct to ducts, in one transplant, three duct to ducts and in 12 transplants as a Roux-en-Y reconstruction. In all, 40 bile leakages (20%) and 17 biliary strictures (8.5%) were observed in 49 patients resulting in a total of 57 biliary complications (28.5%). Seventeen patients were re-operated (12 as a result of bile leakages and five owing to biliary strictures). CONCLUSION: Identification of more than one biliary orifice in the graft resulted in an increase in the complication rates. In grafts containing multiple orifices, performing multiple duct-to-duct (DD) or Roux-en-Y anastomoses led to a lower number of complications.

RESUMO

BACKGROUND: Right lobe donations are known to expose the donors to more surgical risks than left lobe donations. In the present study, the effects of remnant volume on donor outcomes after right lobe living donor hepatectomies were investigated. METHODS: The data on 262 consecutive living liver donors who had undergone a right hepatectomy from January 2004 to June 2011 were retrospectively analysed. The influence of the remnant on the outcomes was investigated according to the two different definitions. These were: (i) the ratio of the remnant liver volume to total liver volume (RLV/TLV) and (ii) the remnant liver volume to donor body weight ratio (RLV/BWR). For RLV/TLV, the effects of having a percentage of 30% or below and for RLV/BWR, the effects of values lower than 0.6 on the results were investigated. RESULTS: Complication and major complication rates were 44.7% and 13.2% for donors with RLV/TLV of ≤30%, and 35.9% and 9.4% for donors with RLV/BWR of < 0.6, respectively. In donors with RLV/TLV of ≤30%, RLV/BWR being below or above 0.6 did not influence the results in terms of liver function tests, complications and hospital stay. The main impact on the outcome was posed by RLV/TLV of ≤30%. CONCLUSION: Remnant volume in a right lobe living donor hepatectomy has adverse effects on donor outcomes when RLV/TLV is ≤30% independent from the rate of RLV/BWR with a cut-off point of 0.6.

RESUMO

OBJECTIVES: Early hepatic artery thrombosis is rare but devastating in living-donor liver transplant recipients. In this study, our aim was to evaluate the results of all patients with early hepatic artery thrombosis at our center. MATERIALS AND METHODS: Between October 2004 and November 2015, 841 patients underwent liver transplant for end-stage liver disease at our center. All recipients with early hepatic artery thrombosis were identified and retrospectively analyzed. Early hepatic artery thrombosis was defined in our study as its occurrence within the first postoperative week. RESULTS: Early hepatic artery thrombosis was seen in 12 patients (1.8%). Seven of these 12 patients developed hepatic artery thrombosis on postoperative day 1 after intraoperative dissection of the hepatic artery with necessity of repeated reconstruction. However, the primary liver function of these patients was excellent, with nearly normal serum liver panel results. The other 5 patients were diagnosed after sudden significant increases of liver values followed by graft dysfunction within the first postoperative week. All patients were listed as high urgent and underwent retransplant. Two patients died perioperatively due to primary nonfunction, and 2 other patients died due to liver cirrhosis based on recurrent autoimmune hepatitis 29 and 106 months after retransplant. The remaining patients were alive with good liver function after a median time of 18 months (interquartile range, 13-45 mo). CONCLUSIONS: Early hepatic artery thrombosis is not always associated with graft dysfunction. Retransplant is still necessary due to ischemic cholangiopathy in the long-term follow-up. However, an elective retransplant, which could mean better outcomes, should be preferred instead of an emergency retransplant.

RESUMO

An accepted definition of donor exclusion criteria has not been established for living donor liver transplantation (LDLT). The use of elderly donors to expand the living donor pool raises ethical concerns about donor safety. The aims of this study were (1) the comparison of the postoperative outcomes of living liver donors by age (≥ 50 versus < 50 years) and (2) the evaluation of the impact of the extent of right hepatectomy on donor outcomes. The study group included 150 donors who underwent donor right hepatectomy between October 2004 and April 2009. Extended criteria surgery (ECS) was defined as right hepatectomy with middle hepatic vein (MHV) harvesting or right hepatectomy resulting in an estimated remnant liver volume (RLV) less than 35%. The primary endpoints were donor outcomes in terms of donor complications graded according to the Clavien classification. Group 1 consisted of donors who were 50 years old or older (n = 28), and group 2 consisted of donors who were less than 50 years old (n = 122). At least 1 ECS criterion was present in 74% of donors: 57% had 1 criterion, and 17% had 2 criteria. None of the donors had grade 4 complications or died. The overall and major complication rates were similar in the 2 donor age groups [28.6% and 14.3% in group 1 and 32% and 8.2% in group 2 for the overall complication rates (P = 0.8) and the major complication rates (P = 0.2), respectively]. However, there was a significant correlation between the rate of major complications and the type of surgery in donors who were 50 years old or older. In LDLT, extending the limits of surgery comes at the price of more complications in elderly donors. Right hepatectomy with MHV harvesting and any procedure causing an RLV less than 35% should be avoided in living liver donors who are 50 years old or older.

RESUMO

We examined the outcomes of patients who received living donor liver transplantation (LDLT) for HCC comparing the impact of up-to-seven criteria and Asan Criteria (AC) with Milan Criteria (MC). Between July 2004 and July 2009, of 175 consecutive LDLT, there were 45 consecutive patients with HCC. Forty patients who completed 12 months follow-up were enrolled. In search for the highest number of expansion, we selected AC as the extended criteria. Patients were divided into having tumors within MC, beyond MC within AC and Beyond Criteria (BC) groups. With a median follow-up of 46 months, overall 1, 3, and 5 years survival was -90%, -81%, and -70%, respectively. In patients within AC, estimated mean survival was 49.8 vs. 40.5 months for BC group (P = 0.2). Disease-free survival was significantly higher in patients within AC comparing with BC group; 48.0 vs. 38.6 months (P = 0.04). Preoperative AFP level >400 and poor tumor differentiation were factors adversely effecting recipient survival. On multivariate analysis, the presence of poor tumor differentiation (P = 0.018 RR: 2.48) was the only independent predictor of survival. Extension of tumor size and number to AC is feasible, without significantly compromising outcomes; however, the presence of poor tumor differentiation was associated with worse outcomes after LDLT.
