| 2 | Inferior vena cava obstruction and collateral circulation as unusual manifestations of hepatobiliary cystadenocarcinoma显示文摘BACKGROUND: Hepatobiliary cystadenocarcinoma represents a rare epithelial malignant tumor derived from the intrahepatic bile duct. METHODS: A 71-year-old woman, who had undergone laparoscopic drainage of a cystic lesion of the right hepatic lobe, was misdiagnosed as having hepatic echinococcal disease, and received intracystic infusion of 95% ethanol four years ago. She was admitted to our hospital for further treatment. RESULTS: Physical examination revealed dilated superficial veins across the right abdominal wall. After mapping the direction of blood flow in these vessels, we assumed that this was a sign of inferior vena cava obstruction. Abdominal ultrasound, computed tomography, magnetic resonance imaging combined with magnetic resonance angiography showed a large cystic mass in the right upper quadrant and epigastrium, displacing the adjacent structures, adherent to the inferior vena cava, which was not patent, resulting in dilation of superficial epigastric veins. The patient underwent an exploratory laparotomy. Total excision of the huge mass measuring 16×15 cm was possible under selective vascular exclusion of the liver. Removal of the tumor resulted in immediate restoration of flow in the inferior vena cava. On the basis of the pathology and findings of immunohistochemical analysis, a hepatobiliary cystadenocarcinoma was diagnosed.CONCLUSIONS: In the present case, hepatobiliary cystadenocar-cinoma was accompanied by dilated superficial venous collaterals due to inferior vena cava obstruction. Selective vascular exclusion of the liver allowed a safe oncological resection of the tumor. | Nikolaos Arkadopoulos Anneza I Yiallourou Constantinos Palialexis Emmanouil Stamatakis Evi Kairi-Vassilatou Vassilis Smyrniotis | 2013 | Hepatobiliary & Pancreatic Diseases International2013，12，3： | 10 |

| 4 | Update on inflammatory bowel disease in patients with primary sclerosing cholangitis显示文摘Patients with primary sclerosing cholangitis(PSC) complicated by inflammatory bowel disease(IBD) represent a distinct subset of patients with unique characteristics,which have serious clinical implications.The aim of this literature review was to shed light to the obscure clinical and molecular aspects of the two diseases combined utilizing current data available and putting issues of diagnosis and treatment into perspective.The prevalence of IBD,mainly ulcerative colitis in PSC patients is estimated to be 21%-80%,dependent on screening programs and nationality.PSC-associated colitis is likely to be extensive,characterized by rectal sparing,backwash ileitis,and generally mild symptoms.It is also more likely to progress to colorectal malignancy,making it imperative for clinicians to maintain a high level of suspicion when tackling PSC patients.There is no optimal surveillance strategy but current guidelines advocate that colonoscopy is necessary at the time of PSC diagnosis with annual endoscopic follow-up.Random biopsies have been criticized and a shift towards targeted biopsies using chromoendoscopy,laser endomicroscopy and narrow-band imaging has been noted.Techniques directed towards genetic mutations instead of histological abnormalities hold promise for easier,more accurate diagnosis of dysplastic lesions.Chemopreventive measures against colorectal cancer have been sought in these patients.Ursodeoxycholic acid seemed promising at first but subsequent studies yielded conflicting results showing anticarcinogenic effects in low doses(8-15 mg/kg per day) and carcinogenic properties in high doses(15-30 mg/kg per day). | Christos Tsaitas Anysia Semertzidou Emmanouil Sinakos | 2014 | World Journal of Hepatology2014，6，4： | 9 |
| 5 | Pancreatic duct guidewire placement for biliary cannulation in a single-session therapeutic ERCP显示文摘AIM: To investigate the technical success and clinical complication rate of a cannulated pancreatic duct with guidewire for biliary access. METHODS: During a five-year study period, a total of 2843 patients were included in this retrospective analysis. Initial biliary cannulation method consisted of single-guidewire technique (SGT) for up to 5 attempts, followed by double-guidewire technique (DGT) when repeated unintentional pancreatic duct cannulation had taken place. Pre-cut papillotomy technique was reserved for when DGT had failed or no pancreatic duct cannulation had been previously achieved. Main outcome measurements were defined as biliary cannu-lation success and post-endoscopic retrograde cholangiopancreatography (ERCP) complication rate. RESULTS: SGT (92.3% success rate) was characterized by statistically significant enhanced patient outcome compared to either the DGT (43.8%, P < 0.001), pre-cut failed DGT (73%, P < 0.001) or pre-cut as first step method (80.6%, P = 0.002). Pre-cut as first step method offered a statistically significantly more favorable outcome compared to the DGT (P < 0.001). The incidence of post-ERCP pancreatitis did not differ in a statistically significant manner between either method (SGT: 5.3%, DGT: 6.1%, Pre-cut failed DGT: 7.9%, Pre-cut as first step: 7.5%) or with patients' gender. CONCLUSION: Although DGT success rate proved not to be superior to SGT or pre-cut papillotomy, it is considered highly satisfactory in terms of safety in order to avoid the risk of a pre-cut when biliary therapy is necessary in difficult-to-cannulate cases. | Dimitrios Xinopoulos Stefanos P Bassioukas Dimitrios Kypreos Dimitrios Korkolis Andreas Scorilas Konstantinos Mavridis Dimitrios Dimitroulopoulos Emmanouil Paraskevas | 2011 | World Journal of Gastroenterology2011，17，15： | 8 |

| 7 | Postoperative jaundice after cardiac surgery显示文摘BACKGROUND:The frequency and pattern of hyperbili-rubinemia after open-heart surgery and its severe perioperative complications are not well clarified. The purpose of this study was to investigate the incidence and nature of postoperative jaundice in patients undergoing cardiac operation,to analyze the determinants,and to identify the clinical significance of this complication with regard to the associated morbidity and mortality. METHODS:A prospective observational study was made during the period of 2003-2004 in a Surgical Intensive Care Unit of a Cardiac Surgery Center,Athens. One hundred twenty-eight adult patients for open heart surgery were divided into three groups. Group A included 50 patients who underwent coronary artery bypass crafting(CABG),group B 31 patients who were subjected to aortic valve replacement(AVR)+CABG and group C 47 patients who underwent mitral valve replacement(MVR)+CABG. Aminotransferases,alkaline phosphatase,gamma-glutamyl-transpeptidase and both types of bilirubin were determined at admission,24 hours after the operation and thereafter according to clinical evolution. The presence of jaundice was associated with elevated serum bilirubin above 3 mg/dl. RESULTS:Hyperbilirubinemia developed in 34 patients(26.5%). The incidence of postoperative jaundice was higher in patients who were subjected to MVR+CABG than to CABG and AVR+CABG. Hyperbilirubinemia was correlated with prolonged cardiopulmonary by-passtime(P<0.001),aortic cross-clamping time(P<0.001),the use of intra aortic balloon pumping(P<0.001),the administration of inotrops and the number of blood and plasma transfusions. Postoperative jaundice resulted mainly from an increase in conjugated bilirubin. CONCLUSIONS:Although hyperbilirubinemia seems to be multifactorial,the type of operation,the preoperative hepatic dysfunction due to advanced heart failure(NYHA Ⅱ-Ⅲ) and the decreased hepatic flow during the operation seem to determine the incidence of jaundice. | Aikaterini Mastoraki Emmanouil Karatzis Sotiria Mastoraki Ioannis Kriaras Petros Sfirakis Stefanos Geroulanos | 2007 | Hepatobiliary & Pancreatic Diseases International2007，6，4： | 7 |
| 8 | Non-cirrhotic hepatocellular carcinoma in chronic viral hepatitis: Current insights and advancements显示文摘Primary liver cancers carry significant morbidity and mortality.Hepatocellular carcinoma(HCC)develops within the hepatic parenchyma and is the most common malignancy originating from the liver.Although 80%of HCCs develop within background cirrhosis,20%may arise in a non-cirrhotic milieu and are referred to non-cirrhotic-HCC(NCHCC).NCHCC is often diagnosed late due to lack of surveillance.In addition,the rising prevalence of non-alcoholic fatty liver disease and diabetes mellitus have increased the risk of developing HCC on noncirrhotic patients.Viral infections such as chronic Hepatitis B and less often chronic hepatitis C with advance fibrosis are associated with NCHCC.NCHCC individuals may have Hepatitis B core antibodies and occult HBV infection,signifying the role of Hepatitis B infection in NCHCC.Given the effectiveness of current antiviral therapies,surgical techniques and locoregional treatment options,nowadays such patients have more options and potential for cure.However,these lesions need early identification with diagnostic models and multiple surveillance strategies to improve overall outcomes.Better understanding of the NCHCC risk factors,tumorigenesis,diagnostic tools and treatment options are critical to improving prognosis and overall outcomes on these patients.In this review,we aim to discuss NCHCC epidemiology,risk factors,and pathogenesis,and elaborate on NCHCC diagnosis and treatment strategies. | Abhilash Perisetti Hemant Goyal Rachana Yendala Ragesh B Thandassery Emmanouil Giorgakis | 2021 | World Journal of Gastroenterology2021，27，24： | 6 |
| 9 | Treating nonalcoholic steatohepatitis with antidiabetic drugs: Will GLP-1 agonists end the struggle?显示文摘Nonalcoholic fatty liver disease(NAFLD) is highly associated with insulin resistance(IR), type 2 diabetes mellitus and metabolic syndrome, being characterized as the hepatic component of metabolic syndrome. Despite its high prevalence, no pharmacological treatment has been established, as of yet. A growing body of evidence, however, shows that reducing IR can result in improvement of the biochemical and histological features of nonalcoholic steatohepatitis(NASH)-the aggressive form of NAFLD that can lead to cirrhosis and hepatocellular carcinoma. Unfortunately, the several trials that have assessed the effect of various antidiabetic agents to date have failed to establish an effective and safe treatment regimen for patients with NAFLD. Glucagon-like peptide-1(commonly known as GLP-1) agonists are a novel class of antidiabetic drugs that improve insulin sensitivity and promote weight loss. They also appear to have a direct effect on the lipid metabolism of hepatocytes, reducing hepatic steatosis. Several trials have demonstrated that GLP-1 agonists can reduce aminotransferase levels and improve liver histology in patients with NAFLD, suggesting that these agents could serve as an alternative treatment option for these patients. This manuscript discusses the role and potential mechanisms of GLP-1 agonists in the treatment of NASH. | Maria Kalogirou Emmanouil Sinakos | 2018 | World Journal of Hepatology2018，10，11： | 6 |
| 10 | Effects of terlipressin versus splenectomy on liver regeneration after partial hepatectomy in rats: What we know so far?显示文摘We read with great interest the article entitled ‘‘Comparative study of the effects of terlipressin versus splenectomy on liver regeneration after partial hepatectomy in rats’’ by Ulmer et al. [1]. The aim of this study was to analyse the impact of terlipressin versus splenectomy on postoperative liver function and liver regeneration in rats undergoing 70% partial hepatectomy. Ulmer and his colleagues concluded that neither the administration of terlipressin nor splenectomy improved liver regeneration after 70% partial hepatectomy in rats. This is a very interesting research in our understanding regarding the study of postoperative liver failure and liver regeneration after modulation of portal vein pressure. However, there are some questions which demand further consideration. | antonios athanasiou eleftherios spartalis mairead hennessy michael spartalis demetrios moris christos damaskos emmanouil pikoulis | 2018 | Hepatobiliary & Pancreatic Diseases International2018，17，1： | 5 |
| 11 | Endoscopic ultrasound in the diagnosis of pancreatic intraductal papillary mucinous neoplasms显示文摘Pancreatic cystic lesions are increasingly recognised due to the widespread use of different imaging modalities.Intraductal papillary mucinous neoplasms(IPMNs)of the pancreas represent a common,but also heterogeneous group of cystic tumors with a significant malignant potential.These neoplasms must be differentiated from other cystic tumors and properly classified into their different types,main-duct IPMNs vs branchduct IPMNs.These types have a different malignant potential and therefore,different treatment strategies need to be implemented.Endoscopic ultrasound(EUS)offers the highest resolution of the pancreas and can aid in the differential diagnosis,classification and differentiation between benign and malignant tumors.The addition of EUS fine-needle aspiration can supply further information by obtaining fluid for cytology,measurement of tumor markers and perhaps DNA analysis.Novel techniques,such as the use of contrast and sophisticated equipment,like intraductal probes can provide information regarding malignant features and extent of these neoplasms.Thus,EUS is a valuable tool in the diagnosis and appropriate management of these tumors. | Alkiviadis Efthymiou Thrasyvoulos Podas Emmanouil Zacharakis | 2014 | World Journal of Gastroenterology2014，20，24： | 4 |

| 14 | Not only ACE2-the quest for additional host cell mediators of SARS-CoV-2 infection: Neuropilin-1 (NRP1) as a novel SARS-CoV-2 host cell entry mediator implicated in COVID-19显示文摘Two recently published studies published in Science by Daly et al.1 and Cantuti-Castelvetri et al.2 identified neuropilin-1(NRP1)as an additional cellular mediator which may facilitate the entry of the new severe acute respiratory syndrome(SARS)-coronavirus(CoV)-2(SARS-CoV-2)into host cells.The findings of these elegant studies collectively indicate that,in addition to the role of angiotensin-converting enzyme 2(ACE2)in mediating the cellular entry of SARS-CoV-2;NRP1 may act as a host cell mediator that can increase the infectivity and may thus contribute to the tissue/organ tropism of this coronavirus. | loannis Kyrou Harpal S.Randeva Demetrios A.Spandidos Emmanouil Karteris | 2021 | Signal Transduction and Targeted Therapy2021，6，2： | 3 |
| 15 | Design of a Prototype EHD Air Pump for Electronic Chip Cooling Applications显示文摘This paper presents the design,optimization and fabrication of an EHD air pump intended for high-power electronic chip cooling applications.Suitable high-voltage electrode configurations were selected and studied,in terms of the characteristics of the generated electric field,which play an important role in ionic wind flow.For this purpose,dedicated software is used to implement finite element analysis.Critical design parameters,such as the electric field intensity,wind velocity,current flow and power consumption are investigated.Two different laboratory prototypes are fabricated and their performances experimentally assessed.This procedure leads to the fabrication of a final prototype,which is then tested as a replacement of a typical fan for cooling a high power density electronic chip.To assist towards that end,an experimental thermal testing setup is designed and constructed to simulate the size of a personal computer's CPU core of variable power.The parametric study leads to the fabrication of experimental single-stage EHD pumps,the optimal design of which is capable of delivering an air flow of 51 CFM with an operating voltage of 10.5 kV.Finally,the theoretical and experimental results are evaluated and potential applications are proposed. | Emmanouil D.FYLLADITAKIS Antonios X.MORONIS Konstantinos KIOUSIS | 2014 | Plasma Science and Technology2014，16，5： | 3 |
| 16 | Enhanced recovery after surgery in liver transplantation:Challenges and feasibility显示文摘BACKGROUND Enhanced recovery after surgery(ERAS)started a revolution that changed age-old surgical stereotypical practices regarding the overall management of the surgical patient.In the last decade,ERAS has gained significant acceptance in the community of general surgery,in addition to several other surgical specialties,as the evidence of its advantages continues to grow.One of the last remaining fields,given its significant complexity and intricate nature,is liver transplantation(LT).AIM To investigate the existing efforts at implementing ERAS in LT.METHODS We conducted a systematic review of the existing studies that evaluate ERAS in orthotopic LT,with a multimodal approach and focusing on measurable clinical primary endpoints,namely length of hospital stay.RESULTS All studies demonstrated a considerable decrease in length of hospital stay,with no readmission or negative impact of the ERAS protocol applied to the postoperative course.CONCLUSIONS ERAS is a well-validated multimodal approach for almost all types of surgical procedures,and its future in selected LT patients seems promising,as the preliminary results advocate for the safety and efficacy of ERAS in the field of LT. | Georgios Katsanos Konstantina-Eleni Karakasi Nikolaos Antoniadis Stella Vasileiadou Athanasios Kofinas Antonios Morsi-Yeroyannis Evangelia Michailidou Ioannis Goulis Emmanouil Sinakos Olga Giouleme Ilias Marios Oikonomou George Evlavis Georgios Tsakiris Eleni Massa Eleni Mouloudi Georgios Tsoulfas | 2022 | World Journal of Transplantation2022，12，7： | 3 |
| 17 | Quality of life after surgical and endoscopic management of severe acute pancreatitis: A systematic review显示文摘BACKGROUND Treatment for severe acute severe pancreatitis(SAP)can significantly affect Health-related quality of life(HR-QoL).The effects of different treatment strategies such as endoscopic and surgical necrosectomy on HR-QoL in patients with SAP remain poorly investigated.AIM To critically appraise the available evidence on HR-QoL following surgical or endoscopic necrosectomy in patient with SAP.METHODS A literature search was performed on PubMed,Google^(TM) Scholar,the Cochrane Library,MEDLINE and Reference Citation Analysis databases for studies that investigated HR-QoL following surgical or endoscopic necrosectomy in patients with SAP.Data collected included patient characteristics,outcomes of interventions and HR-QoL-related details.RESULTS Eleven studies were found to have evaluated HR-QoL following treatment for severe acute pancreatitis including 756 patients.Three studies were randomized trials,four were prospective cohort studies and four were retrospective cohort studies with prospective follow-up.Four studies compared HR-QoL following surgical and endoscopic necrosectomy.Several metrics of HR-QoL were used including Short Form(SF)-36 and EuroQol.One randomized trial and one cohort study demonstrated significantly improved physical scores at three months in patients who underwent endoscopic necrosectomy compared to surgical necrosectomy.One prospective study that examined HR-QoL following surgical necrosectomy reported some deterioration in the functional status of the patients.On the other hand,a cohort study that assessed the long-term HR-QoL following sequential surgical necrosectomy stated that all patients had SF-36>60%.In the only study that examined patients following endoscopic necrosectomy,the HR-QoL was also very good.Three studies investigated the quality adjusted life years suggesting that endoscopic and surgical approaches to management of pancreatic necrosis were comparable in cost effectiveness.Finally,regarding HR-QoL between open necrosectomy and minimally invasive approaches,patients who underwent the later had a significantly better overall quality of life,vitality and mental health.CONCLUSION This review would suggest that the endoscopic approach might offer better HR-QoL compared to surgical necrosectomy.However,the available comparative literature was very limited.More randomized trials powered to detect differences in HR-QoL are required. | Emmanouil Psaltis Chris Varghese Sanjay Pandanaboyana Manu Nayar | 2022 | World Journal of Gastrointestinal Endoscopy2022，14，7： | 3 |
| 18 | Developing a donation after cardiac death risk index for adult and pediatric liver transplantation显示文摘AIM To identify objective predictive factors for donor after cardiac death(DCD) graft loss and using those factors, develop a donor recipient stratification risk predictive model that could be used to calculate a DCD risk index(DCD-RI) to help in prospective decision making on organ use.METHODS The model included objective data from a single institute DCD database(2005-2013, n = 261). Univariate survival analysis was followed by adjusted Cox-regressional hazard model. Covariates selected via univariate regression were added to the model via forward selection, significance level P = 0.3. The warm ischemic threshold was clinically set at 30 min. Points were given to each predictor in proportion to their hazard ratio. Using this model, the DCD-RI was calculated. The cohort was stratified to predict graft loss risk and respective graft survival calculated.RESULTS DCD graft survival predictors were primary indication for transplant(P = 0.066), retransplantation(P = 0.176), MELD > 25(P = 0.05), cold ischemia > 10 h(P = 0.292) and donor hepatectomy time > 60 min(P = 0.028).According to the calculated DCD-RI score three risk classes could be defined of low(DCD-RI < 1), standard(DCD-RI 2-4) and high risk(DCD-RI > 5) with a 5 years graft survival of 86%, 78% and 34%, respectively.CONCLUSION The DCD-RI score independently predicted graft loss(P < 0.001) and the DCD-RI class predicted graft survival(P < 0.001). | Shirin Elizabeth Khorsandi Emmanouil Giorgakis Hector Vilca-Melendez John O'Grady Michael Heneghan Varuna Aluvihare Abid Suddle Kosh Agarwal Krishna Menon Andreas Prachalias Parthi Srinivasan Mohamed Rela Wayel Jassem Nigel Heaton | 2017 | World Journal of Transplantation2017，7，3： | 3 |
| 19 | Boron arsenide heterostructures:lattice-matched heterointerfaces and strain effects on band alignments and mobility显示文摘BAs is a III–V semiconductor with ultra-high thermal conductivity,but many of its electronic properties are unknown.This work applies predictive atomistic calculations to investigate the properties of BAs heterostructures,such as strain effects on band alignments and carrier mobility,considering BAs as both a thin film and a substrate for lattice-matched materials.The results show that isotropic biaxial in-plane strain decreases the band gap independent of sign or direction.In addition,1%biaxial tensile strain increases the in-plane electron and hole mobilities at 300 K by>60%compared to the unstrained values due to a reduction of the electron effective mass and of hole interband scattering.Moreover,BAs is shown to be nearly lattice-matched with InGaN and ZnSnN2,two important optoelectronic semiconductors with tunable band gaps by alloying and cation disorder,respectively. | Kyle Bushick Sieun Chae Zihao Deng John T.Heron Emmanouil Kioupakis | 2020 | npj Computational Materials2020，，1： | 2 |
