2Endoscopic ultrasonography for gastric submucosal lesions显示文摘Gastric submucosal tumors(SMTs) are a rather frequent finding,occurring in about 0.36%of routine upper GIendoscopies.Endoscopic ultrasonography(EUS) has emerged as a reliable investigative procedure for evaluation of these lesions.Diagnostic EUS has the ability to differentiate intramural tumors from extraluminal compressions and can also show the layer of origin of gastric SMTs.Tumors can be further characterized by their layer of origin,echo pattern and margin.EUS-risk criteria of their malignant potential are presented,although the emergence of EUS-FNA has opened new indications for transmural tissue diagnosis and expanded the possibilities of EUS in SMTs of the stomach.Tissue diagnosis should address whether the SMT is a Gastrointestinal stromal tumour(GIST) or another tumor type and evaluate the malignant potential of a given GIST.However,there seems to be a lack of data on the optimal strategy in SMTs suspected to be GISTs with a negative EUS-FNA tissue diagnosis.The current management strategies,as well as open questions regarding their treatment are also presented.Ioannis S Papanikolaou Konstantinos Triantafyllou Anastasia Kourikou Thomas Rsch 2011World Journal of Gastrointestinal Endoscopy2011,3,5:44
3A case of successful management with splenectomy of intractable ascites due to congenital dyserythropoietic anemia type II-induced cirrhosis显示文摘The congenital dyserythropoietic anemias comprise agroup of rare hereditary disorders of erythropoiesis,characterized by ineffective erythropoiesis as thepredominant mechanism of anemia and by characteristicmorphological aberrations of the majority of erythroblastsin the bone marrow.Congenital dyserythropoieticanemia type II is the most frequent type.All types ofcongenital dyserythropoietic anemias distinctly share ahigh incidence of iron loading.Iron accumulation occurseven in untransfused patients and can result in heartfailure and liver cirrhosis.We have reported about apatient who presented with liver cirrhosis and intractableascites caused by congenital dyserythropoietic anemiatype Ⅱ.Her clinical course was further complicatedby the development of autoimmune hemolyticanemia.Splenectomy was eventually performed whichachieved complete resolution of ascites,increase ofhemoglobin concentration and abrogation of transfusionrequirements.Themistoklis Vassiliadis Vassilia Garipidou Vassilios Perifanis Konstantinos Tziomalos OIga Giouleme Kalliopi Patsiaoura Michalis Avramidis Nikolaos Nikolaidis Sofia Vakalopoulou Ioannis Tsitouridis Antonios Antoniadis Panagiotis Semertzidis Anna Kioumi Evangelos Premetis Nikolaos Eugenidis 2006World Journal of Gastroenterology2006,12,5:47
4Helicobacter pylori infection and endocrine disorders:Is there a link?显示文摘Helicobacter pylori(H pylori) infection is a leading world-wide infectious disease as it affects more than half of the world population and causes chronic gastritis,peptic ulcer disease and gastric malignancies.The infection elicits a chronic cellular inflammatory response in the gastric mucosa.However,the effects of this local inflammation may not be confi ned solely to the digestive tract but may spread to involve extraintestinal tissues and/or organs.Indeed,H pylori infection has been epidemiologically linked to extra-digestive conditions and diseases.In this context,it has been speculated that H pylori infection may be responsible for various endocrine disorders,such as autoimmune thyroid diseases,diabetes mellitus,dyslipidemia,obesity,osteoporosis and primary hyperparathyroidism.This is a review of the relationship between H pylori infection and these endocrine disorders.Konstantinos X Papamichael Garyphallia Papaioannou Helen Karga Anastasios Roussos Gerassimos J Mantzaris 2009World Journal of Gastroenterology2009,15,22:42
5Recurrence of choledocholithiasis following endoscopic bile duct clearance: Long term results and factors associated with recurrent bile duct stones显示文摘AIM To evaluate the rate of recurrence of symptomatic chol-edocholithiasis and identify factors associated with the recurrence of bile duct stones in patients who underwent endoscopic retrograde cholangiopancreatography(ERCP) and endoscopic sphincterotomy(EST) for bile duct stone disease.METHODS All patients who underwent ERCP and EST for bile duct stone disease and had their bile duct cleared from 1/1/2005 until 31/12/2008 was enrolled. All symptomatic recurrences during the study period(until 31/12/2015) were recorded. Clinical and laboratory data potentially associated with common bile duct(CBD) stone recurrence were retrospectively retrieved from patients' files.RESULTS A total of 495 patients were included. Sixty seven(67) out of 495 patients(13.5%) presented with recurrent symptomatic choledocholithiasis after 35.28 ± 16.9 mo while twenty two(22) of these patients(32.8%) experienced a second recurrence after 35.19 ± 23.2 mo. Factors associated with recurrence were size(diameter) of the largest CBD stone found at first presentation(10.2 ± 6.9 mm vs 7.2 ± 4.1 mm, P = 0.024), diameter of the CBD at the first examination(15.5 ± 6.3 mm vs 12.0 ± 4.6 mm, P = 0.005), use of mechanical lithotripsy(ML)(P = 0.04) and presence of difficult lithiasis(P = 0.04). Periampullary diverticula showed a trend towards significance(P = 0.066). On the contrary, number of stones, angulation of the CBD, number of ERCP sessions required to clear the CBD at first presentation, more than one ERCP session needed to clear the bile duct initially and a gallbladder in situ did not influence recurrence. CONCLUSION Bile duct stone recurrence is a possible late complication following endoscopic stone extraction and CBD clearance. It appears to be associated with anatomical parameters(CBD diameter) and stone characteristics(stone size, use of ML, difficult lithiasis) at first presentation.Christos Konstantakis Christos Triantos Vasileios Theopistos Georgios Theocharis Ioannis Maroulis Georgia Diamantopoulou Konstantinos Thomopoulos 2017World Journal of Gastrointestinal Endoscopy2017,9,1:46
6From diagnosis to treatment of hepatocellular carcinoma: An epidemic problem for both developed and developing world显示文摘Hepatocellular carcinoma(HCC) is the most frequent primary liver malignancy and the third cause of cancer-related death in the Western Countries. The well-established causes of HCC are chronic liver infections such as hepatitis B virus or chronic hepatitis C virus, nonalcoholic fatty liver disease, consumption of aflatoxins and tobacco smocking. Clinical presentation varies widely; patients can be asymptomatic while symptomatology extends from right upper abdominal quadrant paint and weight loss to obstructive jaundice and lethargy. Imaging is the first key and one of the most important aspects at all stages of diagnosis, therapy and follow-up of patients with HCC. The Barcelona Clinic Liver Cancer Staging System remains the most widely classification system used for HCC management guidelines. Up until now, HCC remains a challenge to early diagnose, and treat effectively; treating management is focused on hepatic resection, orthotopic liver transplantation, ablative therapies, chemoembolization and systemic therapies with cytotocix drugs, and targeted agents. This review article describes the current evidence on epidemiology, symptomatology, diagnosis and treatment of hepatocellular carcinoma.Dimitrios Dimitroulis Christos Damaskos Serena Valsami Spyridon Davakis Nikolaos Garmpis Eleftherios Spartalis Antonios Athanasiou Demetrios Moris Stratigoula Sakellariou Stylianos Kykalos Gerasimos Tsourouflis Anna Garmpi Ioanna Delladetsima Konstantinos Kontzoglou Gregory Kouraklis 2017World Journal of Gastroenterology2017,23,29:44
7Helicobacter pylori infection and inflammatory bowel disease: Is there a link?显示文摘Helicobacter pylori(H.pylori)infection is one of the most widely spread infectious diseases in humans.It can cause chronic gastritis,peptic ulcer disease and gastric malignancies and has been associated with extra-gastric disorders.H.pylori elicit a chronic systemic inflammatory response which,under certain conditions,may trigger autoimmune reactions and may be implicated in the pathogenesis of autoimmune diseases.Although the pathogenesis of inflammatory bowel disease(IBD)is unknown,it is thought to result from complex interactions between environmental factors and microbiota in the gut of individuals who are genetically susceptible.Several bacterial and viral agents have been implicated in the aetiology of IBD.In theory,H.pylori infection could be involved in the pathogenesis of IBD by inducing alterations in gastric and/or intestinal permeability or by causing immunological derangements resulting in absorption of antigenic material and autoimmunity via various immunological pathways.Similar mechanisms may also be responsible for the co-existence of IBD with other autoimmune diseases and/or extra-intestinal manifestations.However,the epidemiological data fail to support this association.Infact,various studies indicate that the prevalence of H.pylori infection is low in patients with IBD,suggesting a protective role for this infection in the development of IBD.In this report,we aim to shed light on proposed mechanisms and confounding factors underlying the potential link between H.pylori infection and IBD.Konstantinos Papamichael Panagiotis Konstantopoulos Gerassimos J Mantzaris 2014World Journal of Gastroenterology2014,20,21:33
8Current imaging strategies for the evaluation of uterine cervical cancer显示文摘Uterine cervical cancer still remains an important socioeconomic issue because it largely affects women of reproductive age.Prognosis is highly depended on extent of the disease at diagnosis and,therefore,accurate staging is crucial for optimal management.Cervical cancer is clinically staged,according to International Federation of Gynecology and Obstetrics guidelines,but,currently,there is increased use of cross sectional imaging modalities [computed tomography(CT),magnetic resonance imaging(MRI),positron emission tomography-CT(PET-CT)] for the study of important prognostic factors like tumor size,parametrial invasion,endocervical extension,pelvic side wall or adjacent/distal organs involvement and lymph node status.Imaging indications also include cervical cancer follow-up,evaluation of tumor response to treatment and selection of suitable candidates for less radical surgeries like radical trachelectomy for fertility preservation.The preferred imaging method for local cervical cancer evaluation is MRI;CT is equally effective for evaluation of extrauterine spread of the disease.PETCT shows high diagnostic performance for the detection of tumor relapse and metastatic lymph nodes.The aim of this review is to familiarize radiologists with the MRI appearance of cervical carcinoma and to discuss the indications of cross sectional imaging during the course of the disease in patients with cervical carcinoma.Charis Bourgioti Konstantinos Chatoupis Lia Angela Moulopoulos 2016World Journal of Radiology2016,8,4:29
9Systematic review of novel ablative methods in locally advanced pancreatic cancer显示文摘Unresectable locally advanced pancreatic cancer with or without metastatic disease is associated with a very poor prognosis.Current standard therapy is limited to chemotherapy or chemoradiotherapy.Few regimens have been shown to have a substantial survival advantage and novel treatment strategies are urgently needed.Thermal and laser based ablative techniques are widely used in many solid organ malignancies.Initial studies in the pancreas were associated with significant morbidity and mortality,which limited widespread adoption.Modifications to the various applications,in particular combining the techniques with high quality imaging such as computed tomography and intraoperative or endoscopic ultrasound has enabled real time treatment monitoring and significant improvements in safety.We conducted a systematic review of the litera-ture up to October 2013.Initial studies suggest that ablative therapies may confer an additional survival benefit over best supportive care but randomised studies are required to validate these findings.Margaret G Keane Konstantinos Bramis Stephen P Pereira Giuseppe K Fusai 2014World Journal of Gastroenterology2014,20,9:30
10History of the infantile hepatic hemangioma:From imaging to generating a differential diagnosis显示文摘We aim to provide an up-to-date summary of infantile hepatic hemangioma(IHH) and its misnomers and to dialectically present the differential diagnosis of these rare entities of the liver.Eligible peer-reviewed articles on hepatic infantile hemangiomas,published between 2000 and 2015,were reviewed for this study.IHH is the most common hepatic vascular tumor in children.Once a liver mass is identified in an infant,the differential diagnosis ranges from vascular malformations to benign and malignant tumors including mesenchymal hamartoma,hepatoblastoma,metastatic neuroblastoma,so careful physical examination,imaging studies,and,if indicated,tumor markers and biopsy,are of pivotal importance to ascertain the correct diagnosis.Despite the benign nature of IHHs,some of these lesions may demand medical and/or surgical intervention,especially for multiple and diffuse IHH.Complications can include hepatomegaly,hypothyroidism and cardiac failure.Therefore,a close follow-up is required until complete involution of the lesions.We propose an algorithm to guide the physicians towards the proper management of hepatic lesions.Maria Gnarra Gerald Behr Alison Kitajewski June K Wu Sudha A Anupindi Carrie J Shawber Nick Zavras Dimitrios Schizas Chris Salakos Konstantinos P Economopoulos 2016World Journal of Clinical Pediatrics2016,5,3:27
11Multipotent role of platelets in inflammatory bowel diseases:A clinical approach显示文摘There is evidence that inflammatory bowel diseases(IBD)combine both inflammation and coagulation in their pathogenesis and clinical manifestations.Although platelets(PLT)are well known for their role in hemo stasis,there are a rising number of studies supporting their considerable role as inflammatory amplifiers in chronic inflammatory conditions.IBD are associated with several alterations of PLT,including number shape,and function,and these abnormalities are main ly attributed to the highly activated state of circulating PLT in IBD patients.When PLT activate,they increase in size,release a great variety of bio-active inflamma tory and procoagulant molecules/particles,and express a variety of inflammatory receptors.These inflamma tory products may represent a part of the missing link between coagulation and inflammation,and can be considered as possible IBD pathogenesis instigators.In clinical practice,thrombocytosis is associated both with disease activity and iron deficiency anemia.Controlling inflammation and iron replacement in anemic patient usually leads to a normalization of PLT count.The aim of this review is to update the role of PLT in IBD and present recent data revealing the possible therapeutic implications of anti-PLT agents in future IBD remedies.Evangelos Voudoukis Konstantinos Karmiris Ioannis E Koutroubakis 2014World Journal of Gastroenterology2014,20,12:27
12Laparoscopic versus open appendectomy: Which way to go?显示文摘AIM: To compare the outcome of laparoscopic versus open appendectomy. METHODS: Prospectively collected data from 293 consecutive patients with acute appendicitis were studied. These comprised of 165 patients who underwent conventional appendectomy and 128 patients treated laparoscopically. The two groups were compared with respect to operative time, length of hospital stay, postoperative pain, complication rate and cost. RESULTS: There were no statistical differences regarding patient characteristics between the two groups. Conversion to laparotomy was necessary in 2 patients (1.5%). Laparoscopic appendectomy was associated with a shorter hospital stay (2.2 d vs 3.1 d, P = 0.04), and lower incidence of wound infection (5.3% vs 12.8%, P = 0.03). However, in patients with complicated disease, intra-abdominal abscess formation was more common after laparoscopic appendectomy (5.3% vs 2.1%, P = 0.002). The operative time and analgesia requirements were similar in the two groups. The cost of treatment was higher by 370 € in the laparoscopic group. CONCLUSION: Laparoscopic appendectomy is as safe and effi cient as open appendectomy, provided surgical experience and equipment are available.Ioannis Kehagias Stavros Nikolaos Karamanakos Spyros Panagiotopoulos Konstantinos Panagopoulos Fotis Kalfarentzos 2008World Journal of Gastroenterology2008,14,31:25
13Gut microbiota and non-alcoholic fatty liver disease显示文摘BACKGROUND: Non-alcoholic fatty liver disease(NAFLD) is a common disorder with poorly understood pathogenesis. Beyond environmental and genetic factors,cumulative data support the causative role of gut microbiota in disease development and progression.DATA SOURCE: We performed a Pub Med literature search with the following key words: 'non-alcoholic fatty liver disease','non-alcoholic steatohepatitis','fatty liver','gut microbiota' and 'microbiome',to review the data implicating gut microbiota in NAFLD development and progression.RESULTS: Recent metagenomic studies revealed differences in the phylum and genus levels between patients with fatty liver and healthy controls. While bacteroidetes and firmicutes remain the dominant phyla among NAFLD patients,their proportional abundance and genera detection vary among different studies. New techniques indicate a correlation between the methanogenic archaeon(methanobrevibacter smithii) and obesity,while the bacterium akkermanshia municiphila protects against metabolic syndrome. Among NAFLD patients,small intestinal bacterial overgrowth detected by breath tests might induce gut microbiota and host interactions,facilitating disease development.CONCLUSIONS: There is evidence that gut microbiota participates in NAFLD development through,among others,obesity induction,endogenous ethanol production,inflammatory response triggering and alterations in choline metabolism. Further studies with emerging techniques are needed to further elucidate the microbiome and host crosstalk in NAFLD pathogenesis.Paraskevas Gkolfakis George Dimitriadis Konstantinos Triantafyllou 2015Hepatobiliary & Pancreatic Diseases International2015,14,6:22
14Multisciplinary management of patients with liver metastasis from colorectal cancer显示文摘Colorectal cancer(CRC) is one of the leading causes of cancer-related death. Surgery, radiotherapy and chemotherapy have been till now the main therapeutic strategies for disease control and improvement of the overall survival. Twenty-five per cent(25%) of CRC patients have clinically detectable liver metastases at the initial diagnosis and approximately 50% develop liver metastases during their disease course. Twentythirty per cent(20%-30%) are CRC patients with metastases confined to the liver. Some years ago various studies showed a curative potential for liver metastases resection. For this reason some authors proposed the conversion of unresectable liver metastases to resectable to achieve cure. Since those results were published, a lot of regimens have been studied for resectability potential. Better results could be obtained by the combination of chemotherapy with targeted drugs, such as anti-VEGF and antiEGFR monoclonal antibodies. However an accurate selection for patients to treat with these regimens and to operate for liver metastases is mandatory to reduce the risk of complications. A multidisciplinary team approach represents the best way for a proper patient management. The team needs to include surgeons, oncologists, diagnostic and interventional radiologists with expertise in hepatobiliary disease, molecular pathologists, and clinical nurse specialists. This review summarizes the most important findings on surgery and systemic treatment of CRC-related liver metastases.Kathleen De Greef Christian Rolfo Antonio Russo Thiery Chapelle Giuseppe Bronte Francesco Passiglia Andreia Coelho Konstantinos Papadimitriou Marc Peeters 2016World Journal of Gastroenterology2016,22,32:22

16Chronic hepatitis C and liver fibrosis显示文摘Chronic infection with hepatitis C virus(HCV) is a leading cause of liver-related morbidity and mortality worldwide and predisposes to liver fibrosis and endstage liver complications. Liver fibrosis is the excessive accumulation of extracellular matrix proteins, including collagen, and is considered as a wound healing response to chronic liver injury. Its staging is critical for the management and prognosis of chronic hepatitis C(CHC) patients, whose number is expected to rise over the next decades, posing a major health care challenge. This review provides a brief update on HCV epidemiology, summarizes basic mechanistic concepts of HCV-dependent liver fibrogenesis, and discusses meth-ods for assessment of liver fibrosis that are routinely used in clinical practice. Liver biopsy was until recently considered as the gold standard to diagnose and stage liver fibrosis. However, its invasiveness and drawbacks led to the development of non-invasive methods, which include serum biomarkers, transient elastography and combination algorithms. Clinical studies with CHC patients demonstrated that non-invasive methods are in most cases accurate for diagnosis and for monitoring liver disease complications. Moreover, they have a high prognostic value and are cost-effective. Non-invasive methods for assessment of liver fibrosis are gradually being incorporated into new guidelines and are becoming standard of care, which significantly reduces the need for liver biopsy.Giada Sebastiani Konstantinos Gkouvatsos Kostas Pantopoulos 2014World Journal of Gastroenterology2014,20,32:19
17Helicobacter pylori infection and respiratory diseases:a review显示文摘In the past few years, a variety of extradigestive disorders,including cardiovascular, skin, rheumatic and liver diseases,have been associated with Helicobacter pylori(H. pylori)infection. The activation of inflammatory mediators by H. pyloriseems to be the pathogenetic mechanism underlying theobserved associations. The present review summarizes thecurrent literature, including our own studies, concerning theassociation between H. pvloriinfection and respiratory diseases.A small number of epidemiological and serologic, case-control studies suggest that H. pyloriinfection may beassociated with the development of chronic bronchitis. Afrequent coexistence of pulmonary tuberculosis and H. pyloriinfection has also been found. Moreover, recent studies haveshown an increasedH. pyloriseroprevalence in patients withbronchiectasis and in those with lung cancer. On the otherhand, bronchial asthma seems not to be related withH. pyloriinfection.All associations between H. pyloriinfection and respiratorydiseases are primarily based on case-control studies,concerning relatively small numbers of patients. Moreover,there is a lack of studies focused on the pathogenetic linkbetween respiratory diseases and H. pylori infection.Therefore, we believe that larger studies should beundertaken to confirm the observed results and to clarifythe underlying pathogenetic mechanisms.Anastasios Roussos Nikiforos Philippou Konstantinos I Gourgoulianis 2003World Journal of Gastroenterology2003,9,1:19

19Resolution of non-alcoholic steatohepatitis by rosuvastatin monotherapy in patients with metabolic syndrome显示文摘AIM: To investigate the effect of rosuvastatin monotherapy on non-alcoholic steatohepatitis(NASH). At present there is no effective treatment for non-alcoholic fatty liver disease or its advanced form NASH.METHODS: This prospective study included 20 biopsy proven patients with NASH, metabolic syndrome(Met S) and dyslipidaemia. Biochemical parameters of the blood of the patients and an ultrasonography of the liver were performed at baseline. Then patients receivedlifestyle advice and were treated for a 12 mo period with rosuvastatin(10 mg/d) monotherapy. Patients were re-evaluated during the study at 3 mo intervals, during which biochemical parameters of the blood were measured including liver enzymes. A repeat biopsy and ultrasonography of the liver were performed at the end of the study in all 20 patients. Changes in liver enzymes, fasting plasma glucose, serum creatinine, serum uric acid(SUA), high sensitivity C reactive protein(hs CRP) and lipid profile were assessed every 3 mo. The primary endpoint was the resolution of NASH and the secondary endpoints were the changes in liver enzyme and lipid values.RESULTS: The repeat liver biopsy and ultrasonography showed complete resolution of NASH in 19 patients, while the 20 th, which had no improvement but no deterioration either, developed arterial hypertension and substantial rise in triglyceride levels during the study, probably due to changes in lifestyle including alcohol abuse. Serum alanine transaminase, aspartate transaminase, and γ-glutamyl transpeptidase were normalised by the 3rd treatment month(ANOVA P < 0.001), while alkaline phosphatase activities by the 6th treatment month(ANOVA, P = 0.01). Fasting plasma glucose and glycated haemoglobin were significantly reduced(P < 0.001). Lipid values were normalised by the 3rd treatment month. No patient had Met S by the 9th treatment month. Body mass index and waist circumference remained unchanged during the study. Thus, changes in liver pathology and function should be attributed solely to rosuvastatin treatment. A limitation of the study is the absence of a control group.CONCLUSION: These findings suggest that rosuvastatin monotherapy could ameliorate biopsy proven NASH and resolve Met S within 12 mo. These effects and the reduction of fasting plasma glucose and SUA levels may reduce the risk of vascular and liver morbidity and mortality in NASH patients. These findings need confirmation in larger studies.Konstantinos Kargiotis Vasilios G Athyros Olga Giouleme Niki Katsiki Evangelia Katsiki Panagiotis Anagnostis Chrysoula Boutari Michael Doumas Asterios Karagiannis Dimitri P Mikhailidis 2015World Journal of Gastroenterology2015,21,25:18
20冠状动脉内影像学临床应用专家共识(第一部分):对冠状动脉介入治疗的指导与优化显示文摘欧洲心血管介入协会(EAPCI)专家组系统总结了血管内超声(IVUS)和光学相干断层成像(OCT)这两种血管内影像学检查临床应用指征的现有证据,提供了关于IVUS和OCT指导经皮冠状动脉介入治疗(PCI)的应用价值,并明确了最可能从腔内影像学指导的介入治疗中获得临床收益的患者或病变类型,同时详细论述了PCI前如何使用IVUS或OCT优化支架尺寸(支架长度和直径)和手术策略的选择。此外,专家推荐对支架失败(支架内再狭窄或支架内血栓形成)的患者应常规进行冠状动脉内影像学检查,并首选OCT。最后,重点论述了IVUS和OCT在指导PCI和评估支架失败两个方面的优势和局限性,并对未来需要深入研究的领域进行了展望。Lorenz Raber Gary S Mintz Konstantinos C Koskinas Thomas W Johnson Niels R Holm Yoshinubo Onuma Maria D Radu Michael Joner Bo Yu Haibo Jia Nicolas Meneveau Jose M.de la Torre Hemandez Javier Escaned Jonathan Hill Francesco Prati Antonio Colombo Carlo di Mario Evelyn Regar Davide Capodanno William Wijns Robert A Byme Giulio Guagliumi 2019中华心血管病杂志2019,47,1:17
