Objectives. Inspiratory, hemodynamic and metabolic changes occur in laparoscopic surgery depending on pneumoperitoneum and patient position. This study aims to evaluate the effects of intra-abdominal pressure increase based on CO2 pneumoperitoneum in laparoscopic operations on hemodynamic parameters and respiratory dynamics and satisfaction of surgeon and operative view.Materials and Methods. A total of 116 consecutive, prospective, ASA class I–III cases aged 18–70 years undergoing laparoscopic cholecystectomy were enrolled in this study. Data of 104 patients were analysed. Patients were divided into two groups as the group Low Pressure (13 mmHg) (Group SP) (n=51). In this study administration of general anesthesia used total intravenous anaesthesia in both groups. All groups had standard and TOF monitorization applied. The anaesthesia methods used in both groups were recorded. Before, during and after peritoneal insufflation, the peroperative ventilation parameters and hemodynamic parameters were recorded. The adequacy of pneumoperitoneum, gastric and the operative view were evaluated by the operating surgeon and recorded.Results. The peripheral oxygen saturation showed no significant difference between the low and standard pressure pneumoperitoneum in view of tidal volume, respiratory rate, end tidal CO2, mean and peak inspiratory pressure, and minute ventilation values. In terms of hemodynamics, when values just after intubation and before extubation were compared, it was observed that in the LP group systolic, diastolic and mean blood pressure values were higher. In terms of heart rate, no significant difference was observed in determined periods between groups. There was no significant difference between the groups in terms of surgical satisfaction and vision.Conclusion. Low pressure pneumoperitoneum provides effective respiratory mechanics and stable hemodynamics for laparoscopic cholecystectomy. It also provides the surgeon with sufficient space for hand manipulations. Anaesthetic method, TIVA and neuromuscular blockage provided good surgery vision with low pressure pneumoperitoneum.

Objective: This study aimed to identify the expression profile and prognostic significance of inflammation-associated lncRNAs in chronic viral hepatitis (CVH) and CVH-associated hepatocellular carcinoma (CVH-HCC)., Material and Methods: In the first step, lncRNA expression analysis was performed by real-time polymerase chain reaction (RT-PCR) using an array panel of 84 inflammation-associated lncRNAs in 48 formalin-fixed paraffin-embedded (FFPE) tissue samples (12 CVH-HCC, 12 peritumoral cirrhotic parenchyma, 12 nontumoral cirrhotic CVH parenchyma, 12 normal liver samples). In the second step, 7 lncRNAs (DLEU2, HOTAIR, LINC00635, LINC00662, RP11-549J18.1, SNHG16 and XIST) were chosen for RT-PCR assay testing in 72 samples (24 CVH-HCC, 24 peritumoral cirrhotic parenchyma, 24 nontumoral cirrhotic CVH parenchyma samples)., Results: Fifty-six inflammation-associated lncRNAs were significantly up-regulated in the peritumoral cirrhotic parenchyma compared to the normal liver. Expression of 71 lncRNAs was significantly higher in peritumoral cirrhotic parenchyma compared to cirrhotic CVH parenchyma. DLEU2 and SNHG16 were up-regulated both in the tumor and peritumoral cirrhotic parenchyma compared to cirrhotic CVH parenchyma. Expression of LINC00662 was significantly higher in CVH-HCC than in cirrhotic CVH parenchyma. Expression of XIST was also increased in both tumor and peritumoral parenchyma samples, albeit without statistical significance. No significant association was found between lncRNA expressions and survival., Conclusion: Inflammation-associated lncRNAs DLEU2, SNHG16, LINC00662, and XIST are candidate diagnostic biomarkers in CVH-HCC. More evidence is needed to prove their utility as prognostic markers.

Graft survival is a critical end point in adult-to-adult living donor liver transplantation (ALDLT), where graft procurement endangers the lives of healthy individuals. Therefore, ALDLT must be responsibly performed in the perspective of a positive harm-to-benefit ratio. This study aimed to develop a risk prediction model for early (3 months) graft failure (EGF) following ALDLT. Donor and recipient factors associated with EGF in ALDLT were studied using data from the European Liver Transplant Registry. An artificial neural network classification algorithm was trained on a set of 2073 ALDLTs, validated using cross-validation, tested on an independent random-split sample (n=518), and externally validated on United Network for Organ Sharing Standard Transplant Analysis and Research data. Model performance was assessed using the AUC, calibration plots, and decision curve analysis. Graft type, graft weight, level of hospitalization, and the severity of liver disease were associated with EGF. The model ( http://ldlt.shinyapps.io/eltr&#95;app ) presented AUC values at cross-validation, in the independent test set, and at external validation of 0.69, 0.70, and 0.68, respectively. Model calibration was fair. The decision curve analysis indicated a positive net benefit of the model, with an estimated net reduction of 5-15 EGF per 100 ALDLTs. Estimated risks>40% and<5% had a specificity of 0.96 and sensitivity of 0.99 in predicting and excluding EGF, respectively. The model also stratified long-term graft survival ( p <0.001), which ranged from 87% in the low-risk group to 60% in the high-risk group. In conclusion, based on a panel of donor and recipient variables, an artificial neural network can contribute to decision-making in ALDLT by predicting EGF risk., (Copyright © 2023 American Association for the Study of Liver Diseases.)

Introduction: Health locus of control has the potential to influence health behavior among individuals with chronic diseases. However, little is known regarding the relationship between locus of control and physical activity in transplant recipients. The aim of the study was to investigate health locus of control and physical activity in liver transplant recipients., Methods: Seventy-six liver transplant recipients were enrolled. The Multidimensional Health Locus of Control - Form C, including internal, chance, doctors, and powerful others subdimensions, was used to evaluate the health locus of control. Physical activity was assessed with the International Physical Activity Questionnaire - Short Form., Results: The median internal health locus of control score was 28.54. Thirty-six participants had low, 35 participants had moderate, and five participants had high physical activity. Internal health locus of control was higher in patients having moderate activity compared to patients with low activity (p=0.04). "Doctors" subdimension of health locus of control was negatively correlated with walking (r=-0.38, p=0.02) and total activity scores among patients with low activity (r=-0.37, p=0.02)., Conclusion: Liver transplant recipients with moderate activity present higher internal health locus of control scores, suggesting a possible influence of physically active behavior on the beliefs of one's own control over disease management. As the activity level increases, the belief that health outcomes are largely the responsibility of health professionals decreases among liver transplant recipients with low activity. Promoting physical activity will help develop the control of one's own actions on health after liver transplantation., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Objective: Alterations in the expression of several long non-coding RNAs (lncRNAs) have been shown in chronic hepatitis B-associated hepatocellular carcinoma (CHB-HCC). Here, we aimed to investigate the association between the expression of inflammation-associated lncRNA X-inactive specific transcript (XIST) and the type of inflammatory cells within the tumor microenvironment., Material and Methods: Twenty-one consecutive cirrhotic patients with CHB-HCC were included. XIST expression levels were investigated on formalin-fixed paraffin-embedded (FFPE) tumoral and peritumoral tissue samples by real-time polymerase chain reaction (RT-PCR). Immunohistochemical staining for CD3, CD4, CD8, CD25, CD163, CTLA4, and PD-1 were performed. The findings were statistically analyzed., Results: Of the 21 cases, 11 (52.4%) had tumoral and 10 (47.6%) had peritumoral XIST expression. No significant association was found between the degree of inflammation and XIST expression. The number of intratumoral CD3, CD4, CD8 and CD20 positive cells was higher in XIST-expressing tumors, albeit without statistical significance. Tumoral and peritumoral XIST expression tended to be more common in patients with tumoral and peritumoral CD4high inflammation. The number of intratumoral CD25 positive cells was significantly higher in XIST-expressing tumors (p=0.01). Tumoral XIST expression was significantly more common in intratumoral CD25high cases (p=0.04). Peritumoral XIST expression was also more common among patients with CD25high peritumoral inflammation, albeit without statistical significance (p=0.19)., Conclusion: lncRNA XIST is expressed in CHB-HCC and its expression is significantly associated with the inflammatory tumor microenvironment, particularly with the presence and number of CD25 (+) regulatory T cells. In vitro studies are needed to explore the detailed mechanism.

Although Fusarium spp. rarely cause infections in healthy people, they can cause fusariosis, particularly in neutropenic hematological malignancies, bone marrow transplant patients, and immunocompromised patients, such as those with acquired immune deficiency syndrome (AIDS), and rarely in solid organ transplant recipients. Here, we present a case of a liver transplant recipient with F. solani species complex (FSSC) infection treated with posaconazole. A 61-year-old man presented with multiple itchy, painful, palpable, irregular, subcutaneous nodules on the right leg and total dystrophic onychomycosis in the right toenails. Incisional skin biopsies of the lesions were performed, and the samples were sent to the pathology and mycology laboratories for analysis. The clinical isolate was identified as FSSC using phenotypic, matrix-assisted laser desorption/ionization-time of flight mass spectrometry, and genotypic methods. Liposomal amphotericin B could not be administered owing to the development of side effects; hence, the patient was treated with posaconazole for 4 months. While some nodular lesions disappeared completely under this treatment, the others showed dimensional regression. This is the first case of FSSC infection with skin and nail involvement in a non-neutropenic, liver transplant patient in Turkey. Fusariosis may develop with rare species, such as FSSC, as first reported in this case of a liver transplant patient. Regardless of the species, amphotericin B is the first choice for treating fusariosis; however, posaconazole is an effective and safe alternative to amphotericin B., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest to disclose., (Copyright © 2023 SFMM.

Objectives: Vascular complications after liver transplant can be lethal. High levels of suspicion and aggressive use of diagnostic tools may help with early diagnosis and treatment. Here, we share our experiences regarding this topic., Materials and Methods: Adult and pediatric patients who had liver transplant between February 1997 and June 2018 in our clinic were included in the study. Patients were grouped according to age (pediatric patients were those under 18 years old), male versus female, indication for transplant, type of liver transplant, type of vascular complication, treatment, and survival aftertreatment.We analyzed the statistical incidence of vascular complications according to age, male versus female, and type of liver transplant., Results: Our analyses included 607 liver transplant procedures, including 7 retransplants, with 349 (57.4%) from living donors and 258 (42.6%) from deceased donors. Of total patients, 539 were adults (89.8%) and 61 were children (10.2%). Vascular complications occurred in 25 patients (4.1%), with hepatic artery complications seen in 13 patients (2.1%) (10 adults [1.8%] and 3 children [4.9%]), portal vein complications seen in 9 patients (1.5%) (6 adults [1.1%] and 3 children [4.9%]), and hepatic vein complications seen in 3 patients (0.5%) (2 adults [0.36%] and 1 child [1.6%]). Rate of vascular complications was statistically higher in pediatric patients (11.4% vs 3.3%; P = .007) and higher but not statistically in recipients of livers from living donors (5.2% vs 2.7%; P = .19). Twelve patients (48.8%) were treated with endovascular approach, and 11 (0.44%)required surgicaltreatment. Two patients underwent immediate retransplant due to hepatic artery thrombosis., Conclusions: Because vascular complications are the most severe complications afterlivertransplant,there must be close follow-up of vascular anastomoses, particularly early postoperatively, with radiologic methods. In cases of vascular complications, emergent treatment, including endovascular interventions, surgery, and retransplant, must be performed.

Background: We aimed to examine the comorbidity, disease progress, and vaccination status of liver transplant patients followed up in our hospital who had COVID-19., Methods: Liver transplant patients with COVID-19 were included between 11 March 2020 and 15 September 2022. Demographic data, disease progress, and COVID-19 vaccines were recorded. The SPSS 24.0 (IBM SPSS, Inc, Armonk, NY, United States) program was used for analysis. The data were analyzed using the χ 2 test. P values < .05 were considered clinically significant., Results: Sixteen SARS-CoV-2 polymerase chain reaction (+) patients were detected. Twelve (75.0%) patients were male; the mean age was 49.56 ± 14.0 years (24-76 years). The mean transplant time was 156.69 ± 54.05 months. Four (25.0%) of the 5 (31.3%) patients with comorbidities had hypertension, and 1 (6.3%) had diabetes. None of the patients had an underlying lung disease. All the patients received immunosuppressive therapy, and the most common combination was antimetabolite and calcineurin inhibitor (9 patients [69.2%]). Nine patients (56.3%) had a fever, whereas 6 (37.5%) had respiratory symptoms. Two (33.3%) had pneumonia. Five (31.4%) patients were hospitalized, and 1 (20%) was admitted to the intensive care unit due to non-invasive mechanical ventilation needs. No patient died due to COVID-19. A statistically significant correlation was found between the presence of fever, respiratory symptoms, and hospitalization (P < .05). Of those vaccinated, 10 (66.7%) were infected before the COVID-19 vaccination., Conclusions: The course of COVID-19 in liver recipients without any underlying disease other than transplantation is not different from that in the healthy population. Immunosuppressive therapy was continued in patients with the disease, and two-thirds did not require hospitalization., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Introduction: Various potential prognostic histopathologic factors for colorectal carcinoma liver metastasis have been proposed. However, there is still no consensus on pathological reporting of colorectal carcinoma liver metastasis resection materials. The aim of this study was to investigate the relation between selected tumoral and parenchymal histopathologic features and prognostic factors for better characterization and prognostic prediction of the patients with colorectal carcinoma liver metastasis. Methods: Hematoxylin-eosin stained slides from 100 patients who underwent hepatic resection were evaluated. Pathologic characteristics; including number of tumor nodules, largest tumor size, status of surgical margin, tumor distance to closest margin, tumor necrosis, the presence of tumor capsule, tumor differentiation, perineural and lymphovascular invasion, micrometastasis, tumor budding, peritumoral lymphocytic infiltrate and parenchymal features including steatosis, steatohepatitis, lobular inflammation, confluent necrosis, hepatocyte ballooning, portal inflammation were assessed. For 49 patients who were treated with preoperative chemotherapy, tumor regression grade and chemotherapy-related parenchymal changes such as sinusoidal damage, venous obstruction, nodular regenerative hyperplasia, steatosis and steatohepatitis were also evaluated. Results: The presence of lymphovascular invasion (p < 0.001), micrometastasis (p=0.004), absent or mild peritumoral lymphocytic infiltration (p =0.013), high tumor budding score (p=0.033) and moderate/poor differentiation (p=0.022) were significantly associated with shorter overall survival. Lymphovascular invasion (p < 0.001) was an independent predictor of mortality in multivariate analysis. Conclusions: We conclude that tumor differentiation, lymphovascular invasion, micrometastasis, peritumoral lymphocytic reaction and tumor budding score are potential prognostic histopathological features and candidates for inclusion in pathology reports of colorectal carcinoma liver metastasis resections.

Data on peritumoral histopathologic findings in patients with hepatocellular carcinoma (HCC) is limited. In this retrospective study, we evaluated the peritumoral histopathologic changes in patients with chronic viral hepatitis (CVH)-associated HCC (CVH-HCC) and their prognostic value. 61 consecutive cirrhotic patients who underwent liver transplantation due to CVH-HCC were included. Histopathologic features within 1 cm distance of the tumor, and their association with clinicopathological characteristics and prognosis were evaluated. A random representative slide of cirrhotic parenchyma unrelated to invasive and/or dysplastic foci was also evaluated for the same histopathologic criteria. The majority (85%, n = 52) were male with a median age of 55 ± 6.38 (range, 39-67). The etiologic agent was only HBV in 90% (n = 55). The most common peritumoral findings were portal inflammation (100%; n = 61), ductular reaction (100%; n = 61) and sinusoidal dilatation (95%; n = 58). Macrovascular invasion was observed only in four cases (7%) with mild peritumoral portal inflammation. Neutrophilic infiltration of the peritumoral portal tracts (n = 18; 30%) was significantly associated with pT4 tumor stage, tumor grade, macrovascular invasion, and pretransplant therapy. Patients with moderate or severe peritumoral sinusoidal dilatation tended to have worse prognosis, albeit not significantly. Peritumoral ballooning degeneration was associated with multifocality, recurrence and recurrence-free survival in both uni- and multivariate analysis. Peritumoral histopathologic changes in CVH-HCC can be classified as: changes related to pathogenesis, changes indirectly affecting prognosis, and changes directly affecting prognosis. Peritumoral prominent ballooning degeneration may be a predictor of recurrence while portal neutrophilic infiltration and sinusoidal dilatation seem to indicate poor prognosis., (© 2022 Scandinavian Societies for Medical Microbiology and Pathology.)

Objective: While the presence and number of metastatic lymph nodes (LNs) are important prognostic factors for pancreatic ductal adenocarcinoma (PDAC), there is no recommendation to specify metastatic regional LN localization in the current staging system. The aim of this study was to evaluate the prognostic effect of regional metastatic LN localizations in PDAC., Material and Method: Metastatic sites of 101 consecutive PDAC patients who underwent pancreaticoduodenectomy were classified as peripancreatic, perigastric, hepatica communis, hepatoduodenal, and superior mesenteric artery. The frequency of metastasis in each region and the association between the presence of metastasis in each site and overall and disease-free survival were statistically analyzed., Results: Eighty cases (79.2%) had peripancreatic, 7 (6.9%) had perigastric, 6 (5.9%) had hepatica communis, 7 (6.9%) had hepatoduodenal, and 4 (4%) had superior mesenteric artery LN metastasis. The overall and disease-free survival values were significantly shorter in patients with hepatoduodenal LN metastasis (log rank; p= 0.001, p=0.017, respectively). The presence of metastatic superior mesenteric artery LN was significantly associated with shorter disease-free survival in univariate analysis (p=0.017). Hepatoduodenal LN metastasis was an independent predictor of mortality (p=0.005) in multivariate analysis., Conclusion: The presence of hepatoduodenal LN metastasis is an independent poor prognostic factor for mortality. The presence of metastatic LN in the superior mesenteric artery region was significantly associated with shorter disease-free survival time, although not an independent predictor. We conclude that the metastatic regional LN sites, especially the hepatoduodenal region, have an impact on the prognosis, and should be included in synoptic pathology reports.

The question of how successful we are in predicting pancreatic neuroendocrine tumors (panNET) with poor prognosis has not been fully answered yet. The aim of this study was to investigate the effects of clinicopathological features on prognosis and to determine their validity in prediction of prognosis and whether a better prognostic classification can be made. Fifty-six patients who underwent pancreatic resection for pancreatic neuroendocrine tumor were included. The associations between clinicopathological parameters and prognosis were evaluated statistically. Efficiencies of different thresholds for tumor size, mitotic count, and Ki67 proliferation index for prognosis prediction were compared. Vascular invasion was statistically associated with high tumor grade, advanced pT stage, and mortality rate. The presence of non-functional tumor, lymphatic invasion, and > 10 cm tumor size were significantly related to shorter overall survival. Advanced pT stage (pT3-4), > 5 cm tumor size, and high tumor grade (grades 2-3) were significantly associated with shorter disease-free survival. The mortality rate showed the strongest statistical significance with mitotic count when grouped as 1: < 2, 2: 2-10, and 3: > 10 mitosis/ 2 mm 2 . The 10% threshold value for Ki67 index was more successful in predicting adverse prognosis. Among the morphologic variants, the ductulo-insular variant was the most promising to have positive prognostic value in our series, although no statistical significance was detected. In conclusion, threshold values of 5 cm and 10 cm for tumor size, 10% for Ki67 proliferation index, and 10/2 mm 2 for mitotic count and vascular and lymphatic invasion assessed separately are potential prognostic candidates for better stratification of panNETs., (© 2021.

Objectives: Hepatic resection and liver transplant are regarded as 2 potentially curative treatments for hepatocellular carcinoma. Here, we compared both options in patients with hepatocellular carcinoma secondary to cirrhosis seen at a single center over 12 years., Materials and Methods: We evaluated early complications and survival of patients with hepatocellular carcinoma treated with liver transplant (57 patients) or hepatic resection (36 patients) at our center between 1998 and 2010., Results: The 34-month mean follow-up period was similar for both treatment groups. The liver transplant group had a longer hospital stay than the hepatic resection group (P ⟨ .001). Patients with Child-Turcotte-Pugh A stage were treated by hepatic resection more than by liver transplant (P ⟨ .001),with Child-Turcotte-Pugh B stage patients treated by liver transplant more than by hepatic resection (P = .03). All patients with Child-Turcotte-Pugh C stage had liver transplant. Both treatment groups had similar postoperative complications and early postoperative mortality rates, but liver transplant resulted in longer overall (P = .001) and higher event-free (P = .001) survival than hepatic resection. Among the liver transplant group, 57.8% of patients met the Milan criteria. Patients who met Milan criteria were treated by liver transplant statistically more than hepatic resection, and these patients had longer overall survival (P = .01) and higher event-free survival (P ⟨ .001) than patients who had hepatic resection. Hepatocellular carcinoma recurrence rates were higher after hepatic resection (P = .232)., Conclusions: In patients with hepatocellular carcinoma, hospital stay was longer after liver transplant, but morbidity and mortality rates for liver transplant versus hepatic resection were similar. However, overall and event-free survival rates were better after liver transplant than after hepatic resection. These results suggest that liver transplant should be considered as the primary treatment option for patients with hepatocellular carcinoma secondary to cirrhosis.

Objectives: We investigated late mortality causes and risk factors in patients who were undergoing deceased-donor liver transplant., Materials and Methods: Patients who had deceased-donor liver transplant from February 1997 to June 2014 in the hepatopancreaticobiliary surgery and liver transplant unit at Dokuz Eylul University Hospital were analyzed. Inclusion criteria were patients over 18 years of age and who survived more than 1 year after liver transplant. Causes of mortality and related risk factors after the first year were analyzed., Results: Of the 157 included patients, 102 patients (72%) received transplant procedures for hepatitis B and C secondary to chronic liver disease. Mean follow-up was 89.85 months (range, 14.4-240 months). Of 157 patients, 20 patients (12.7%) died: 12 patients (60%) died during posttransplant years 2-5 and 8 patients (40%) died after 5 years. Causes of death included malignancy in 8 patients (40%), recurrent hepatitis C infection in 3 patients (15%), infection in 3 patients (15%), coronary artery disease in 2 patients (10%), graft rejection in 2 patients (10%), and biliary complications in 2 patients (10%). Univariate analyses showed that long-term survival was significantly lower in patients older than 50 years (P = .001), when there was presence of hepatocellular carcinoma (P = .011), and when donor age was higher than 38 years (P = .045). Multivariate analyses identified recipient age (P = .007) and presence of hepatocellular carcinoma (P = 0.033) as factors that reduced long-term survival., Conclusions: The main causes of late mortality in liver transplant are malignancy, recurrence of hepatitis C, infection, coronary artery disease, graft rejection, and biliary complications. Advanced age and hepatocellular carcinoma are independent risk factors that increase late mortality.

Background and Aim: Liver transplantation is performed in increasing numbers due to advances in surgical techniques and the introduction of diverse immunosuppressive drugs. The present study aims to analyze the effects of socioeconomic status and education level on patient and graft survival, in addition to all these factors., Material and Methods: All patients aged 18 years and above who underwent consecutive liver transplantation at the Liver Transplantation Unit of Department of General Surgery at the Dokuz Eylül University Hospital and whose data were available were included in this study., Results: Incompliance was noted in 68.3% of the 278 patients. On the other hand, patient compliance did not have a significant effect on graft and patient survival. However, decreased levels in the parameters, such as education status, vocational status and socioeconomic status, were found to be correlated with patient compliance. A significant correlation was not found between these factors and patient and graft survival., Conclusion: Although a direct effect of socioeconomic status on patient and graft survival could not be shown the significant association of vocational status and education status which determine socioeconomic level with parameters other than patient and graft survival may affect the success of liver transplants., Competing Interests: The authors have no conflict of interest to declare., (© Copyright 2020 by Hepatology Forum.)

Lymph node metastasis is a important factor on survival in ampullary adenocarcinoma. Log odds of positive lymph nodes (LODDS) is a novel prognostic indicator on lymph node status. We aimed to evaluate the prognostic impact of LODDS for the patients with ampullary adenocarcinoma who underwent R0 pancreaticoduodenectomy. The study includes 42 patients.. LODDS was calculated as "log (number of metastatic lymph nodes+0.5)/(number of total harvested nodes - metastatic lymph nodes+0.5)". LODDS subgroups were created based on their LODDS value: LODDS1(LODDS≤ - 1.5), LODDS2(-1.5 < LODDS≤ - 1.0), LODDS3(-1.0 < LODDS≤ - 0.5), LODDS4(LODDS> - 0.5). The mean survival time was 72.7 ± 7.82 months. Survival rates for 1, 3 and 5 years were 93%, 65% and 45%, respectively. The mean LODDS value was -1.0466 ± 0.51. LODDS subgroups show strong correlation with Overall Survival(OS). The mean survival were 114.8, 81.8, 56.6 and 25.6 months in LODDS subgroups 1, 2, 3 and 4, respectively (Log-rank; p = 0.002), in addition LOODS values shows correlation with perineural invasion and micro vascular invasion (p = 0.015 and p = 0.001 respectively). Findings in our patient group support the hypothesis that LODDS subgroups correlate with OS, and that value of LODDS has considerable role in prediction of OS as well.

Aim: This study aims to evaluate survival rates in elderly patients after liver transplantation (LT) and to analyze the factors associated with mortality., Patients and Methods: Our study includes 535 patients over the age of 18 who had undergone LT in our clinic between June 2004 and January 2018. Data were collected prospectively and scanned retrospectively. Data concerning the patients' age, sex, LT indication, Child-Turcotte-Pugh score, Model for End-Stage Liver Disease score, presence of hepatocellular cancer (HCC), coexisting disease, LT types, and post-transplant survival were investigated. The patients were grouped under 2 categories (18-59 years of age and 60 years of age and over) and were compared in terms of their characteristics. In patients aged 60 and over, the causes of mortality and related factors were investigated., Results: The study included 535 patients, 458 (85.6%) of whom were between 18 and 59 years of age and 77 (14.4%) were over 60 years of age. The median follow-up period was 86.7 (1 to 247) months. The elderly group's survival rate was significantly lower than that of the younger group (P = .002). In elderly patients, survival rates of 1, 3, 5, and 10 years were 67.4%, 56.4%, 53.8%, and 46.1%, respectively., Conclusion: In elderly patients, factors that increase post-LT mortality require thorough consideration. Equally important is the physiological status of the candidates for transplantation. Correct patient selection in the preoperative stage and good postoperative care can provide successful survival results in elderly patients., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Aim: Liver transplantation (LT) is the most promising treatment method in hepatocellular cancer (HCC). Due to the shortage of organ donors and the possible risks associated with living donation, the selection of patients for LT is critical. The aim of this study is to investigate the predictive ability of the Glasgow Prognostic Score (GPS), modified GPS (mGPS), and hepatic GPS (hGPS) on prognoses in a patient group who underwent deceased donor LT (DDLT) or living-donor LT (LDLT) for HCC., Patients and Methods: This study includes 62 DDLT and 55 LDLT patients who underwent LT for HCC between 1998 and 2016 in a single center. The study endpoints were recurrence, 0- to 1-year mortality, 0- to 3-year mortality, mortality, and overall survival (OS)., Results: The median follow-up time was 70.24 ± 48.47 months. GPS and hGPS positivity were found to be prognostic indicators of 0- to 3-year mortality and overall mortality in DDLT (P = .012, P = .006; P = .044 and P = .022 respectively). In the LDLT group, GPS was found to be effective in predicting 0- to 1-year and 0- to 3-year mortality (P = .045, P = .022 respectively); GPS and hGPS were also found to be effective in predicting overall mortality (P = .001 and P = .046 respectively). The OS was significantly longer in the GPS 0 group and hGPS 0 group compared to the GPS 1-2 and hGPS 1-2 group in both DDLT and LDLT., Conclusion: The findings of this study and the literature indicate that using GPS and hGPS is appropriate in selecting patients with HCC who are candidates for LT., (Copyright © 2019 Elsevier Inc.

Aim: There is a well-known risk of the emergence of hepatic failure in living donor transplant cases on whom are performed a right donor hepatectomy (RDH). There are different prevalence ratios in literature on this phenomenon. In our study, we aim to depict the prevalence of hepatic failure and risk factors in our cases regarding the most recent description criteria related to hepatic failure., Patients and Methods: We included right liver donor hepatectomy cases who fit the donor evaluation algorithm at the Dokuz Eylul University Liver Transplantation Unit between the period of June 2000 and September 2017. The patients were evaluated regarding preoperative data. Liver failure was defined according to the International Study Group of Liver Surgery (ISGLS) criteria. We also included statistical analysis of risk factors that are potentially related to liver failure., Results: We included a total of 276 patients. In 27 (9.7%) patients, we observed posthepatectomy liver failure (PHLF). In 26 (9.4%) patients, we observed Grade A liver failure; in 1 (0.3%) patient, we observed Grade B liver failure. We did not observe any Grade C hepatic failure. In patients with hepatic failure, we observed a significantly longer period of hospitalization (P = .007). Old age (odds ratio = 1.065, 95% confidence interval, 1.135-29.108, P = .035) and preoperatory red blood cell (RBC) transfusion (odds ratio = 5.749, 95% confidence interval, 1.019-1.113, P = .005) were shown as independent risk factors for PHLF., Conclusion: Posthepatectomy liver failure is a vital complication of RDH. The risk can be decreased by careful selection of donor candidates. Elderly donor candidates and intraoperative RBC are independent risk factors for PHLF., (Copyright © 2019 Elsevier Inc.

Objectives: Our objective was to analyze characteristics, risk factors, and incidence of de novo malignancies after liver transplant., Materials and Methods: The hospital records of 557 patients who underwent liver transplant were analyzed from the point of de novo malignancy development. We evaluated the demographic features and survival of these patients retrospectively., Results: The research covered 429 patients, 9 (2%) of whom developed de novo malignancy. All of these patients were male (100%), and their mean (SD) age was 51.33 (4.69) years (range, 45-65 y). Indications for transplant included alcohol related in 4 cases, chronic hepatitis B in 2 cases, chronic hepatitis B and C in 1 case, chronic hepatitis B and D in 1 case, and chronic hepatitis C and alcohol-related cirrhosis in 1 case. The mean (SD) time from transplant to cancer diagnosis was 63.41 (37.10) months (range, 17-122 mo). The types of tumors were lung cancer, lymphoma, neuroendocrine tumor of lung, nasopharyngeal cancer, and squamous cell carcinoma of the skin. Seven cases received chemotherapy with or without radiotherapy. Two cases received surgery and radiotherapy. One patient underwent surgical treatment. One patient died before treatment was started., Conclusions: In recent years, improvements in surgical techniques and immunosuppressive therapies have helped prolong survival of patients who undergo liver transplant. However, this also has led to a rise in the incidence of long-term complications such as de novo malignancy. These patients are more likely to develop de novo malignancy than the general population, for which chronic immunosuppression is identified as a major risk factor. Early diagnosis and treatment of de novo malignancies can help obtain better prognosis and higher survival rates in these patients.

Objectives: Primary sclerosing cholangitis is a chronic inflammatory disease of the intrahepatic and extrahepatic bile ducts. More than half of the patients will face end-stage liver disease and require liver transplant. Here, we describe the long-term outcomes of liver transplant in patients with primary sclerosing cholangitis at our center., Materials and Methods: For this retrospective, observational study, we investigated all patients who underwent liver transplant for primary sclerosing cholangitis between January 2005 and June 2013 at the Dokuz Eylul University Hospital. Patient data were obtained from hospital records. Our inclusion criteria were patients over 18 years old and diagnosed with primary sclerosing cholangitis., Results: Of 11 patients included the study, 6 (54.5%) were male and 5 (45.5%) were female. Mean age was 40.6 ± 11.0 years (range, 23-60 y). All patients had cirrhosis due to primary sclerosing cholangitis. With regard to Child-Turcot-Pugh classification, 2 patients (18.2%) were classified as having Child-Turcot-Pugh A cirrhosis, 7 patients (63.6%) were classified as having B cirrhosis, and 2 patients (18.2%) were classified as having C cirrhosis. Mean Modified End-Stage Liver Disease score was 17.5 ± 6.1 (range, 7-25). Cholangiocarcinoma was not detected in explant pathologic examinations. Primary sclerosing cholangitis recurrence developed in 2 patients (18.1%). Three patients (27.2%) died during the follow-up period., Conclusions: Liver transplant is a good therapeutic option for primary sclerosing cholangitis with satisfactory long-term outcomes. Liver transplant should be reserved for patients with end-stage liver disease and other conditions that significantly impair quality of life.
