| 1 | Pathophysiological consequences of obstructive jaundice and perioperative management显示文摘Background: Obstructive jaundice is a common problem in daily clinical practice. Understanding completely the pathophysiological changes in obstructive jaundice remains a challenge for planning current and future management.Data sources: A Pub Med was searched for relevant articles published up to August 2016. The effect of obstructive jaundice on proinflammatory cytokines, coagulation status, hemodynamics and organ functions were evaluated.Results: The effects of obstructive jaundice included biliary tree, the hepatic cell and liver function as well as systemic complications. The lack of bile in the gut, the disruption of the intestinal mucosal barrier,the increased absorption of endotoxin and the subsequent endotoxemia cause proinflammatory cytokine production(TNF-α, IL-6). Bilirubin induces systemic inflammatory response syndrome which may lead to multiple organ dysfunction syndrome. The principal clinical manifestations include hemodynamic instability and acute renal failure, cardiovascular suppression, immune compromise, coagulation disorders,nutritional impairment, and wound healing defect. The proper management includes full replacement of water and electrolyte deficiency, prophylactic antibiotics, lactulose, vitamin K and fresh frozen plasma,albumin and dopamine. The preoperative biliary drainage has not been indicated in overall, but only in a few selected cases.Conclusion: The perioperative management is an essential measure in improving the outcome after the appropriate surgical operation in jaundiced patients especially those with malignancy. | Efstathios T Pavlidis Theodoros E Pavlidis | 2018 | Hepatobiliary & Pancreatic Diseases International2018，17，1： | 63 |
| 2 | Advances in prognostic factors in acute pancreatitis:a mini-review显示文摘BACKGROUND:Early assessment of the severity of acute pancreatitis is essential to the proper management of the disease.It is dependent on the criteria of the Atlanta classification system.DATA SOURCES:PubMed search of recent relevant articles was performed to identify information about the severity and prognosis of acute pancreatitis.RESULTS:The scoring systems included the Ranson's or Glasgow's criteria ≥3,the APACHE II classification system ≥8,and the Balthazar's criteria ≥4 according to the computed tomography enhanced scanning findings.The single factors on admission included age >65 years,obesity,hemoconcentration(>44%),abnormal chest X-ray,creatinine >2 mg/dl,C-reactive protein>150 mg/dl,procalcitonin >1.8 ng/ml,albumin <2.5 mg/dl,calcium <8.5 mg/dl,early hyperglycemia,increased intra-abdominal pressure,macrophage migration inhibitory factor,or a combination of IL-10 >50 pg/ml with calcium <6.6 mg/dl.CONCLUSION:The prediction of the severity of acute pancreatitis is largely based on well defined multiple factor scoring systems as well as several single risk factors. | Theodoros E Pavlidis Efstathios T Pavlidis Athanasios K Sakantamis | 2010 | Hepatobiliary & Pancreatic Diseases International2010，9，5： | 25 |
| 3 | Role of bevacizumab in colorectal cancer growth and its adverse effects:A review显示文摘Angiogenesis affects both wound healing and malignant cell growth through nutrients and oxygen.Vascular endothelial growth factor(VEGF) is the most important element involved in this complex process.Inhibition of VEGF influences angiogenesis and may restrict tumor growth and metastatic ability.Modern antiangiogenic therapy is based on this theory.Bevacizumab is a recombinant humanized monoclonal antibody(immunoglobulin G1) which binds with VEGF-A forming a large molecule.It can not be bound with VEGF tyrosine kinase receptors preventing VEGF-A incorporation;thus its activity is inhibited inducing blockage of VEGFmediated angiogenesis.Bevacizumab,in combination with chemotherapy or other novel targeted therapeutic agents,is currently used more frequently in clinical practice,mainly for managing advanced colorectal cancer.It is also used for managing other malignancies,such as breast cancer,pancreatic cancer,prostate cancer,non small-cell lung cancer,metastatic renal carcinoma and ovarian tumors.Although it is generally considered a safe treatment,there are reports of some rare side effects which should be taken into account.Recent experiments in rats and mice show promising results with a wider therapeutic range. | Efstathios T Pavlidis Theodoros E Pavlidis | 2013 | World Journal of Gastroenterology2013，19，31： | 24 |
| 4 | Current opinion on lymphadenectomy in pancreatic cancer surgery显示文摘BACKGROUND:Adenocarcinoma of the pancreas exhibits aggressive behavior in growth,inducing an extremely poor prognosis with an overall median 5-year survival rate of only 1%-4%.Curative resection is the only potential therapeutic opportunity. DATA SOURCES:A PubMed search of relevant articles published up to 2009 was performed to identify information about the value of lymphadenectomy and its extent in curative resection of pancreatic adenocarcinoma. RESULTS:Despite recent advances in chemotherapy,radio-therapy or even immunotherapy,surgery still remains the major factor that affects the outcome.The initial promising performance in Japan gave conflicting results in Western countries for the extended and more radical pancreatectomy; it has failed to prove beneficial.Four prospective,randomized trials on extended versus standard lymphadenectomy during pancreatic cancer surgery have shown no improvement in long-term survival by the extended resection.The exact lymph node status,including malignant spread and the total number retrieved as well as the lymph node ratio,is the most important prognostic factor.Positive lymph nodes after pancreatectomy are present in 70%.Paraaortic lymph node spread indicates poor prognosis. CONCLUSIONS:Undoubtedly,a standard lymphadenectomy including>15 lymph nodes must be no longer preferred in patients with the usual head location.The extended lymphadenectomy does not have any place,unless in randomized trials.In cases with body or tail location,the radical antegrade modular pancreatosplenectomy gives promising results.Nevertheless,accurate localization and detailed examination of the resected specimen are required for better staging. | Theodoros E Pavlidis Efstathios T Pavlidis Athanasios K Sakantamis | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，1： | 12 |
| 5 | Autoimmune pancreatitis versus pancreaticcancer: a comprehensive review withemphasis on differential diagnosis显示文摘BACKGROUND: Autoimmune pancreatitis (AIP) is a rare form of chronic pancreatitis with a discrete pathophysiology occasional diagnostic radiological findings, and characteristic histological features. Its etiology and pathogenesis are still under investigation, especially during the last decade Another aspect of interest is the attempt to establish specific criteria for the differential diagnosis between autoimmune pancreatitis and pancreatic cancer, entities that are frequently indistinguishable. DATA SOURCES: An extensive search of the PubMed database was performed with emphasis on articles about the differential diagnosis between autoimmune pancreatitis and pancreatic cancer up to the present. RESULTS: The most interesting outcome of recent research is the theory that autoimmune pancreatitis and its various extra-pancreatic manifestations represent a systemic fibro inflammatory process called IgG4-related systemic disease The diagnostic criteria proposed by the Japanese Pancreatic Society, the more expanded HISORt criteria, the new definitions of histological types, and the new guidelines of the International Association of Pancreatology help to establish the diagnosis of the disease types. CONCLUSION: The valuable help of the proposed criteria for the differential diagnosis between autoimmune pancreatitis and pancreatic cancer may lead to avoidance of pointless surgical treatments and increased patient morbidity. | Kyriakos Psarras Minas E Baltatzis Efstathios T Pavlidis Miltiadis A Lalountas Theodoros E Pavlidis Athanasios K Sakantamis | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，5： | 9 |
| 6 | Serum leptin and ghrelin in chronic hepatitis C patients with steatosis显示文摘AIM:To determine the associations between leptin and ghrelin concentrations and sustained virological response(SVR)in chronic hepatitis C patients with ste-atosis.METHODS:We retrospectively assessed 56 patients infected with hepatitis C virus(HCV)genotype-1 and 40 with HCV genotype-3.Patients with decompensated cirrhosis,and those with other causes of chronic liver disease,were excluded.Serum HCV-RNA concentra-tions were measured before the initiation of treatment;at weeks 12(for genotype 1 patients),24 and 48 during treatment;and 24 wk after the end of treatment.Genotype was determined using INNO-LIPA HCV as-says,and serum leptin and ghrelin concentrations were measured using enzyme-linked immunosorbent assay.Biopsy specimens were scored according to the Ishak system and steatosis was graded as mild,moderate,or severe,according to the Brunt classif ication.RESULTS:Overall,SVR was positively related to the presence of genotype-3,to biopsy-determined lower histological stage of liver disease,and lower grade of steatosis.Patients ≥ 40 years old tended to be less responsive to therapy.In genotype-1 infected pa-tients,SVR was associated with a lower grade of liver steatosis,milder fibrosis,and an absence of insulin resistance.Genotype-1 infected patients who did not achieve SVR had significantly higher leptin concen-trations at baseline,with significant increases as the severity of steatosis worsened,whereas those who achieved SVR had higher ghrelin concentrations.In genotype-3 infected patients,SVR was associated only with fibrosis stage and lower homeostasis model as-sessment insulin resistance at baseline,but not with the degree of steatosis or leptin concentrations.Geno-type-3 infected patients who achieved SVR showed signif icant decreases in ghrelin concentration at end of treatment.Baseline ghrelin concentrations were elevat-ed in responders of both genotypes who had moderate and severe steatosis.CONCLUSION:Increased serum leptin before treat-ment may predict non-SVR,especially in HCV geno-type-1 infected patients,whereas increased ghrelin may predict SVR in genotype-1. | Christos Pavlidis Georgios I Panoutsopoulos Dina Tiniakos Sotirios Koutsounas John Vlachogiannakos Irini Zouboulis-Vafiadis | 2011 | World Journal of Gastroenterology2011，17，46： | 6 |
| 7 | Current surgical management of pancreatic endocrine tumor liver metastases显示文摘BACKGROUND: The management of metastatic disease in pancreatic endocrine tumors (PETs) demands a multidisciplinary approach and the cooperation of several medical specialties. The role of surgery is critical, even when a radical excision cannot always be achieved. DATA SOURCES: A PubMed search of relevant articles published up to February 2011 was performed to identify current information about PET liver metastases regarding diagnosis and management, with an emphasis on surgery. RESULTS: The early diagnosis of metastases and their accurate localization, most commonly in the liver, is very important. Surgical options include radical excision, and palliative excision to relieve symptoms in case of failure of medical treatment. The goal of the radical excision is to remove the primary tumor bulk and all liver metastases at the same time, but unfortunately it is not feasible in most cases. Palliative excisions include aggressive tumor debulking surgeries in well-differentiated carcinomas, trying to remove at least 90% of the tumor mass, combined with other additional destructive techniques such as hepatic artery embolization or chemoembolization to treat metastases or chemoembolization to relieve symptoms in cases of rapidly growing tumors. The combination of chemoembolization and systemic chemotherapy results in better response and survival rates. Other local destructive techniques include ethanol injection, cryotherapy and radiofrequency ablation. CONCLUSION: It seems that the current management of PETs can achieve important improvements, even in advanced cases. | Theodoros E Pavlidis Kyriakos Psarras Nikolaos G Symeonidis Efstathios T Pavlidis Athanasios K Sakantamis | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，3： | 5 |
| 8 | Role of stenting in the palliation of gastroesophageal junction cancer: A brief review显示文摘Gastroesophageal junction cancer has an increasing in-cidence in western countries. It is inoperable when firstmanifested in more than 50% of cases. So, palliationis the only therapeutic option for the advanced diseaseto relieve dysphagia and its consequences in weakenedpatients with an estimated mean survival under 6 mo.This article has tried to identify trends focusing on cur-rent information about the best palliative treatment,with an emphasis on the role of stenting. Self-expand-ing stent placement, either metal or plastic, is the mainmanagement option. However, this anatomical loca-tion creates some particular problems for stent safetyand effectiveness which may be overcome by properlydesigned novel stents. The stents ensure a good qual-ity of life and must be preferred over other alterna-tive methods of loco-regional modalities, i.e., externalradiation, laser thermal or photodynamic therapy. Al-though stent placement is generally a simple, safe andeffective method, there are sometimes complications,increasing the morbidity and mortality rate. Bypassoperative procedures have now been abandoned as afirst choice. The stomach instead of the colon must beused for a bypass operation when it is needed. Chemo-therapy, despite the toxicity, and intraluminal radiation(brachytherapy) have a well-defined role. | Theodoros E Pavlidis Efstathios T Pavlidis | 2014 | World Journal of Gastrointestinal Surgery2014，6，3： | 5 |
| 9 | Use of isolated Roux loop for pancreaticojejunostomy reconstruction after pancreaticoduodenectomy显示文摘AIM: To evaluate the efficacy of the isolated Roux loop technique in decreasing the frequency of pancreaticojejunal anastomosis failure. METHODS: We retrospectively reviewed 88 consecutive patients who underwent pancreaticoduodenectomy (standard or pylorus-preserving). Single jejunal loop was used in 42 patients (SL group) while isolated Roux loop was used in 46 patients (RL group). Demographic characteristics (age, gender) and perioperative results (major/minor complications, mortality, hospital stay) were compared between the two groups. RESULTS: Mortality was almost equal in both groups and overall mortality was 2.27%. Leak rate from the pancreaticojejunal anastomosis and hospital stay were lower in the RL group without significant difference. Morbidity was 39.1% in the RL group, insignificantly higherthan the SL group. Operative time was almost 30 min longer in the RL group. CONCLUSION: The isolated Roux loop, although an equally safe alternative, does not present advantages over the traditional use of a single jejunal loop. Randomized controlled studies are required to further clarify its efficacy. | Konstantinos Ballas Nikolaos Symeonidis Savvas Rafailidis Theodoros Pavlidis Georgios Marakis Nikolaos Mavroudis Athanasios Sakantamis | 2010 | World Journal of Gastroenterology2010，16，25： | 4 |
| 10 | Association of arterial stiffness with coronary flow reserve in revascularized coronary artery disease patients显示文摘AIM: To investigate the association of arterial wave reflection with coronary flow reserve(CFR) in coronary artery disease(CAD) patients after successful revascularization.METHODS: We assessed 70 patients with angiographically documented CAD who had undergone recent successful revascularization. We measured(1) reactive hyperemia index(RHI) using fingertip peripheral arterial tonometry(RH-PAT Endo-PAT);(2) carotid to femoral pulse wave velocity(PWVc-Complior);(3) augmentation index(AIx), the diastolic area(DAI%) and diastolic reflection area(DRA) of the central aortic pulse wave(Arteriograph);(4) CFR using Doppler echocardiography; and(5) blood levels of lipoprotein-phospholipase A2(LpPLA2).RESULTS: After adjustment for age, sex, blood pressure parameter, lipidemic, diabetic and smoking status, we found that coronary flow reserve was independently related to AIx(b =-0.38, r = 0.009), DAI(b = 0.36, P = 0.014), DRA(b = 0.39, P = 0.005) and RT(b =-0.29,P = 0.026). Additionally, patients with CFR < 2.5 had higher PWVc(11.6 ± 2.3 vs 10.2 ± 1.4 m/s, P = 0.019), SBPc(139.1 ± 17.8 vs 125.2 ± 19.1 mm Hg, P = 0.026), AIx(38.2% ± 14.8% vs 29.4% ± 15.1%, P = 0.011) and lower RHI(1.26 ± 0.28 vs 1.50 ± 0.46, P = 0.012), DAI(44.3% ± 7.9% vs 53.9% ± 6.7%, P = 0.008), DRA(42.2 ± 9.6 vs 51.6 ± 11.4, P = 0.012) and Lp PLA2(268.1 ± 91.9 vs 199.5 ± 78.4 ng/m L, P = 0.002) compared with those with CFR ≥ 2.5. Elevated Lp PLA2 was related with reduced CFR(r =-0.33, P = 0.001), RHI(r =-0.37, P < 0.001) and DRA(r =-0.35, P = 0.001) as well as increased PWVc(r = 0.34, P = 0.012) and AIx(r = 0.34, P = 0.001). CONCLUSION: Abnormal arterial wave reflections are related with impaired coronary flow reserve despite successful revascularization in CAD patients. There is a common inflammatory link between impaired aortic wall properties, endothelial dysfunction and coronary flow impairment in CAD. | Vlassis Tritakis Stavros Tzortzis Ignatios Ikonomidis Kleanthi Dima Georgios Pavlidis Paraskevi Trivilou Ioannis Paraskevaidis Giorgos Katsimaglis John Parissis John Lekakis | 2016 | World Journal of Cardiology2016，8，2： | 4 |
| 11 | Numerical simulation of three-dimensional breaking waves and its interaction with a vertical circular cylinder显示文摘Wave breaking plays an important role in wave-structure interaction. A novel control volume finite element method with adaptive unstructured meshes is employed here to study 3-D breaking waves. The numerical framework consists of a 'volume of fluid' type method for the interface capturing and adaptive unstructured meshes to improve computational efficiency. The numerical model is validated against experimental measurements of breaking wave over a sloping beach and is then used to study the breaking wave impact on a vertical circular cylinder on a slope. Detailed complex interfacial structures during wave impact, such as plunging jet formation and splash-up are captured in the simulation, demonstrating the capability of the present method. | Zhihua Xie 吕林 Thorsten Stoesser 林建国 Dimitrios Pavlidis Pablo Salinas Christopher C.Pain Omar K.Matar | 2017 | Journal of Hydrodynamics2017，29，5： | 4 |
| 12 | Effect of early propranolol administration on portal hypertensive gastropathy in cirrhotic rats显示文摘AIM:To investigate any protective effect of early propranolol administration in the development of portal hypertensive gastropathy in cirrhotic rats. METHODS:For the development of liver cirrhosis and portal hypertensive gastropathy,60 rats underwent ligation of the left adrenal vein and complete devascularization of the left renal vein,followed by phenobarbital and carbon tetrachloride(CCl4) administration.After two weeks of CCl4 administration, the rats were randomly separated into two groups.In group A,propranolol was continuously administered intragastrically throughout the study,whereas in group B normal saline(placebo)was administered instead. Hemodynamic studies and vascular morphometric analysis of gastric sections were performed after complete induction of cirrhosis. RESULTS:Vascular morphometric studies showed higher numbers of vessels in all mucosal layers in the control group.Statistical analysis revealed a significantly higher total vascular surface in the control group compared to the propranolol group,but with no statistically significant difference between the mean vascular surfaces between the groups.Our study clearly shows that the increased mucosal blood flow is manifested by a marked increase of vessel count. CONCLUSION:Early propranolol's administration in portal hypertensive cirrhotic rats seems to prevent intense gastric vascular congestion that characterizes portal hypertensive gastropathy. | Savas Rafailidis Charalampos Demertzidis Konstantinos Ballas Michail Alatsakis Nikolaos Symeonidis Theodoros Pavlidis Kyriakos Psarras Valentini Tzioufa-Asimakopoulou Athanassios Sakadamis | 2009 | World Journal of Gastroenterology2009，15，34： | 3 |

| 15 | Current management of concomitant cholelithiasis and common bile duct stones显示文摘The management policy of concomitant cholelithiasis and choledocholithiasis is based on a one-or two-stage procedure.It basically includes either laparoscopic cholecystectomy(LC)with laparoscopic common bile duct(CBD)exploration(LCBDE)in the same operation or LC with preoperative,postoperative and even intraoperative endoscopic retrograde cholangiopancreatography-endoscopic sphincterotomy(ERCP-ES)for stone clearance.The most frequently used worldwide option is preoperative ERCP-ES and stone removal followed by LC,preferably on the next day.In cases where preoperative ERCP-ES is not feasible,the proposed alternative of intraoperative rendezvous ERCP-ES simultaneously with LC has been advocated.The intraoperative extraction of CBD stones is superior to postoperative rendezvous ERCP-ES.However,there is no consensus on the superiority of laparoendoscopic rendezvous.This is equivalent to a traditional two-stage procedure.Endoscopic papillary large balloon dilation reduces recurrence.LCBDE and intraoperative ERCP have similar good outcomes.The risk of recurrence after ERCP-ES is greater than that after LCBDE.Laparoscopic ultrasonography may delineate the anatomy and detect CBD stones.The majority of surgeons prefer the transcductal instead of the transcystic approach for CBDE with or without T-tube drainage,but the transcystic approach must be used where possible.LCBDE is a safe and effective choice when performed by an experienced surgeon.However,the requirement of specific equipment and advanced training are drawbacks.The percutaneous approach is an alternative when ERCP fails.Surgical or endoscopic reintervention for retained stones may be needed.For asymptomatic CBD stones,ERCP clearance is the firstchoice method.Both one-stage and two-stage management are acceptable and can ensure improved quality of life. | Efstathios T Pavlidis Theodoros E Pavlidis | 2023 | World Journal of Gastrointestinal Surgery2023，15，2： | 2 |
| 16 | 在不含酒精的脂肪肝疾病和尖锐 ischemic 击严厉和结果之间的协会显示文摘 AIM:To evaluate the association of nonalcoholic fatty liver disease(NAFLD)with acute ischemic stroke severity and in-hospital outcome.METHODS:We prospectively studied all patients who were admitted in our Department with acute ischemic stroke between September 2010 and August 2012(n=415;39.5%males,mean age 78.8±6.6 years).The severity of stroke was assessed with the National Institutes of Health Stroke Scale(NIHSS)score at admission.NALFD was defined as serum alanine aminotransferase and/or aspartate aminotransferase levels above the upper limit of normal in the absence of other causes of elevated aminotransferases levels[chronic hepatitis B or C,drug toxicity,increased alcohol consumption(>21 and>14 drinks per week in men and women,respectively),cholestatic diseases or rhabdomyolysis].The outcome was assessed with the modified Rankin scale(mRS)score at discharge and in-hospital mortality.Adverse outcome was defined as mRS score at discharge≥2.Dependency at discharge was defined as mRS score between 2 to 5.RESULTS:NAFLD was present in 7.7%of the study population.Patients with NAFLD had lower serum high-density lipoprotein cholesterol and higher triglyceride levels than patients without NAFLD(P<0.05 for both comparisons).Demographic data,the prevalence of other cardiovascular risk factors and the prevalence of established CVD did not differ between the two groups.At admission,the NIHSS score did not differ between patients with and without NAFLD(6.3±6.4and 8.8±9.6,respectively;P=NS).At discharge,the mRS score did not differ between the two groups(1.9±2.2 and 2.6±2.2 in patients with and without NAFLD,respectively;P=NS).Rates of dependency at discharge were also similar in patients with and without NAFLD(36.8%and 55.0%,respectively;P=NS)as were the rates of adverse outcome(42.9%and58.6%,respectively;P=NS).In-hospital mortality rates also did not differ between the 2 groups(8.0%and 7.0%in patients with and without NAFLD,respectively;P=NS).CONCLUSION:The presence of NAFLD in patients admitted for acute ischemic stroke does not appear to be associated with more severe stroke or with worse in-hospital outcome. | Konstantinos Tziomalos Vasilios Giampatzis Stella D Bouziana Marianna Spanou Maria Papadopoulou Athinodoros Pavlidis Stavroula Kostaki Andreas Bozikas Christos Savopoulos Apostolos I Hatzitolios | 2013 | World Journal of Hepatology2013，5，11： | 2 |
