| 1 | Esophageal cancer: Risk factors,screening and endoscopic treatment in Western and Eastern countries显示文摘Esophageal cancer is one of the most unknown and deadliest cancers worldwide,mainly because of its extremely aggressive nature and poor survival rate.Esophageal cancer is the 6th leading cause of death from cancer and the 8th most common cancer in the world.The 5-year survival is around 15%-25%.There are clear differences between the risk factors of both histological types that affect their incidence and distribution worldwide.There are areas of high incidence of squamous cell carcinoma(some areas in China) that meet the requirements for cost-effectiveness of endoscopy for early diagnosis in the general population of those areas.In Europe and United States the predominant histologic subtype is adenocarcinoma.The role of early diagnosis of adenocarcinoma in Barrett's esophagus remains controversial.The differences in the therapeutic management of early esophageal carcinoma(high-grade dysplasia,T1 a,T1 b,N0) between different parts of the world may be explained by the number of cancers diagnosed at an early stage.In areas where the incidence is high(China and Japan among others) early diagnoses is more frequent and has led to the development of endoscopic techniques for definitive treatment that achieve very effective results with a minimum number of complications and preserving the functionality of the esophagus. | María José Domper Arnal ángel Ferrández Arenas ángel Lanas Arbeloa | 2015 | World Journal of Gastroenterology2015，21，26： | 116 |
| 2 | Pathogenesis and clinical management of Helicobacter pylori gastric infection显示文摘Helicobacter pylori(H.pylori)is a gram-negative bacterium that infects approximately 4.4 billion individuals worldwide.However,its prevalence varies among different geographic areas,and is influenced by several factors.The infection can be acquired by means of oral-oral or fecal-oral transmission,and the pathogen possesses various mechanisms that improve its capacity of mobility,adherence and manipulation of the gastric microenvironment,making possible the colonization of an organ with a highly acidic lumen.In addition,H.pylori presents a large variety of virulence factors that improve its pathogenicity,of which we highlight cytotoxin associated antigen A,vacuolating cytotoxin,duodenal ulcer promoting gene A protein,outer inflammatory protein and gamma-glutamyl transpeptidase.The host immune system,mainly by means of a Th1-polarized response,also plays a crucial role in the infection course.Although most H.pylori-positive individuals remain asymptomatic,the infection predisposes the development of various clinical conditions as peptic ulcers,gastric adenocarcinomas and mucosa-associated lymphoid tissue lymphomas.Invasive and non-invasive diagnostic methods,each of them with their related advantages and limitations,have been applied in H.pylori detection.Moreover,bacterial resistance to antimicrobial therapy is a major challenge in the treatment of this infection,and new therapy alternatives are being tested to improve H.pylori eradication.Last but not least,the development of effective vaccines against H.pylori infection have been the aim of several research studies. | Breno Bittencourt de Brito Filipe Ant?nio Fran?a da Silva Aline Silva Soares Vinícius Afonso Pereira Maria Luísa Cordeiro Santos Mariana Miranda Sampaio Pedro Henrique Moreira Neves Fabrício Freire de Melo | 2019 | World Journal of Gastroenterology2019，25，37： | 84 |
| 3 | Nuclear Factor-κB:Activation and Regulation during Toll-Like Receptor Signaling显示文摘Toll-like receptors (TLRs) recognize distinct microbial components to initiate the innate and adaptive immune responses. TLR activation culminates in the expression of appropriate pro-inflammatory and immunomodulatory factors to meet pathogenic challenges. The transcription factor NF-κB is the master regulator of all TLR-induced responses and its activation is the pivotal event in TLR-mediated activation of the innate immune response. Many of the key molecular events required for TLR-induced NF-κB activation have been elucidated. However, much remain to be learned about the ability of TLRs to generate pathogen-specific responses using a limited number of transcription factors. This review will focus on our current understanding of NF-κB activation by TLRs and potential mechanisms for achieving a signal-specific response through NF-κB. | Ruaidhrí J.

| 4 | Colorectal cancer: From prevention to personalized medicine显示文摘Colorectal cancer(CRC)is a very heterogeneous disease that is caused by the interaction of genetic and environmental factors.CRC develops through a gradual accumulation of genetic and epigenetic changes,leading to the transformation of normal colonic mucosa into invasive cancer.CRC is one of the most prevalent and incident cancers worldwide,as well as one of the most deadly.Approximately 1235108 people are diagnosed annually with CRC,and 609051 die from CRC annually.The World Health Organization estimates an increase of77%in the number of newly diagnosed cases of CRCand an increase of 80%in deaths from CRC by 2030.The incidence of CRC can benefit from different strategies depending on its stage:health promotion through health education campaigns(when the disease is not yet present),the implementation of screening programs(for detection of the disease in its early stages),and the development of nearly personalized treatments according to both patient characteristics(age,sex)and the cancer itself(gene expression).Although there are different strategies for screening and although the number of such strategies is increasing due to the potential of emerging technologies in molecular marker application,not all strategies meet the criteria required for screening tests in population programs;the three most accepted tests are the fecal occult blood test(FOBT),colonoscopy and sigmoidoscopy.FOBT is the most used method for CRC screening worldwide and is also the primary choice in most population-based screening programs in Europe.Due to its non-invasive nature and low cost,it is one of the most accepted techniques by population.CRC is a very heterogeneous disease,and with a few exceptions(APC,p53,KRAS),most of the genes involved in CRC are observed in a small percentage of cases.The design of genetic and epigenetic marker panels that are able to provide maximum coverage in the diagnosis of colorectal neoplasia seems a reasonable strategy.In recent years,the use of DNA,RNA and protein markers in different biological samples has been explored as strategies for CRC diagnosis.Although there is not yet sufficient evidence to recommend the analysis of biomarkers such as DNA,RNA or proteins in the blood or stool,it is likely that given the quick progression of technology tools in molecular biology,increasingly sensitive and less expensive,these tools will gradually be employed in clinical practice and will likely be developed in mass. | Gemma Binefa Francisco Rodríguez-Moranta àlex Teule Manuel Medina-Hayas | 2014 | World Journal of Gastroenterology2014，20，22： | 67 |
| 5 | Pathophysiological 角色和在糖尿病的 nephropathy 的发炎的治疗学的含意显示文摘 Diabetes mellitus and its complications are becoming one of the most important health problems in the world. Diabetic nephropathy is now the main cause of end-stage renal disease. The mechanisms leading tothe development and progression of renal injury are not well known. Therefore, it is very important to f ind new pathogenic pathways to provide opportunities for early diagnosis and targets for novel treatments. At the present time, we know that activation of innate immunity with development of a chronic low grade inflammatory response is a recognized factor in the pathogenesis of diabetic nephropathy. Numerous experimental and clinical studies have shown the participation of different inflammatory molecules and pathways in the pathophysiology of this complication. | Desirée Luis-Rodríguez Alberto Martínez-Castelao José Luis Górriz Fernando de lvaro Juan F Navarro-González | 2012 | World Journal of Diabetes2012，3，1： | 55 |
| 6 | Different strategies of treatment for uterine cervical carcinoma stage ⅠB2-ⅡB显示文摘Uterine cervical cancer is the second most common gynecological malignancy. It is estimated that over 35% of tumors are diagnosed at locally advanced disease, stage ⅠB2-ⅡB with an estimated 5-year overall survival of 60%. During the last decades, the initial treatment for these women has been debated and largely varies through different countries. Thus, radical concurrent chemoradiation is the standard of care in United Sated and Canada, and neoadjuvant chemotherapy followed by radical surgery is the first line of treatment in some institutions of Europe, Asia and Latin America. Until today, there is no evidence of which strategy is better over the other. This article describe the evidence as well as the advantages and disadvantages of the main strategies of treatment for women affected by uterine cervical cancer stage ⅠB2-ⅡB. | Lucas Minig María Guadalupe Patrono Nuria Romero Juan Francisco Rodríguez Moreno Jesús Garcia-Donas | 2014 | World Journal of Clinical Oncology2014，5，2： | 46 |
| 7 | Acute-on-chronic liver failure:Pathogenesis,prognostic factors and management显示文摘Acute-on-chronic liver failure(ACLF) is increasingly recognized as a complex syndrome that is reversiblein many cases. It is characterized by an acute deterioration of liver function in the background of a pre-existing chronic liver disease often associated with a high short-term mortality rate. Organ failure(OF) is always associated, and plays a key role in determining the course, and the outcome of the disease. The definition of ACLF remains controversial due to its overall ambiguity, with several disparate criteria among various associations dedicated to the study of liver diseases. Although the precise pathogenesis needs to be clarified, it appears that an altered host response to injury might be a contributing factor caused by immune dysfunction, ultimately leading to a pro-inflammatory status, and eventually to OF. The PIRO concept(Predisposition, Insult, Response and Organ Failure) has been proposed to better approach the underlying mechanisms. It is accepted that ACLF is a different and specific form of liver failure, where a precipitating event is always involved, even though it cannot always be ascertained. According to several studies, infections and active alcoholism often trigger ACLF. Viral hepatitis, gastrointestinal haemorrhage, or drug induced liver injury, which can also provoke the syndrome. This review mainly focuses on the physiopathology and prognostic aspects. We believe these features are essential to further understanding and providing the rationale for improveddisease management strategies. | Sara Blasco-Algora José Masegosa-Ataz María Luisa Gutiérrez-García Sonia Alonso-López Conrado M Fernández-Rodríguez | 2015 | World Journal of Gastroenterology2015，21，42： | 45 |
| 8 | Two-dimensional speckle tracking echocardiography for the assessment of atrial function显示文摘Echocardiography is the most common diagnostic method for assessing atrial function but the technique has some limitations. Traditionally, assessment of left atrial function has been performed by measuring volumes with 2D echocardiography. Additionally, it can be assessed with transmitral Doppler and pulmonary vein Doppler. Recently, an alternative method has been incorporated, namely, measurement of myocardial deformation with color tissue Doppler-derived strain. However, this method has several limitations, such as suboptimal reproducibility, angle-dependence, signal artifacts and the fact that it only measures regional strain and does not obtain information about the curved portion of the atrial roof. To overcome these limitations in the quantification of atrial function, the use of speckle tracking echocardiography (STE) strain has been proposed. This technique is not derived from Doppler but rather from 2D echocardiography; it is angle-independent and allows one to measure global as well as regional atrial strain. In this editorial, we describe the physical and pathophysiological concepts of STE and underline the clinical usefulness of this new technique. | Tomás Francisco Cianciulli María Cristina Saccheri Jorge Alberto Lax Alejandra Marina Bermann Daniel Ernesto Ferreiro | 2010 | World Journal of Cardiology2010，2，7： | 39 |
| 9 | Hepatogenic differentiation of human mesenchymal stem cells from adipose tissue in comparison with bone marrow mesenchymal stem cells显示文摘AIM: To investigate and compare the hepatogenic transdifferentiation of adipose tissue-derived stem cells (ADSC) and bone marrow-derived mesenchymal stem cells (BMSC) in vitro. Transdifferentiation of BMSC into hepatic cells in vivo has been described. Adipose tissue represents an accessible source of ADSC, with similar characteristics to BMSC.METHODS: BMSCs were obtained from patients under-going total hip arthroplasty and ADSC from human adi-pose tissue obtained from lipectomy. Cells were grown in medium containing 15% human serum. Cultures were serum deprived for 2 d before cultivating under similar pro-hepatogenic conditions to those of liver develop-ment using a 2-step protocol with sequential addition of growth factors, cytokines and hormones. Hepatic differ-entiation was RT-PCR-assessed and liver-marker genes were immunohistochemically analysed. RESULTS: BMSC and ADSC exhibited a fibroblastic mor-phology that changed to a polygonal shape when cells differentiated. Expression of stem cell marker Thy1 de-creased in differentiated ADSC and BMSC. However, the expression of the hepatic markers, albumin and CYPs increased to a similar extent in differentiated BMSC and ADSC. Hepatic gene activation could be attributed to in-creased liver-enriched transcription factors (C/EBPβ and HNF4α), as demonstrated by adenoviral expression vec-tors.CONCLUSION: Mesenchymal stem cells can be induced to hepatogenic transdifferentiation in vitro. ADSCs have a similar hepatogenic differentiation potential to BMSC, but a longer culture period and higher proliferation ca-pacity. Therefore, adipose tissue may be an ideal source of large amounts of autologous stem cells, and may become an alternative for hepatocyte regeneration, liver cell transplantation or preclinical drug testing. | Raquel Taléns-Visconti Ana Bonora Ramiro Jover Vicente Mirabet Francisco Carbonell José Vicente Castell María José Gómez-Lechón | 2006 | World Journal of Gastroenterology2006，12，36： | 35 |

| 11 | WJD 5^(th) Anniversary Special Issues(2): Type 2 diabetes Type 2 diabetes and cardiovascular disease: Have all risk factors the same strength?显示文摘Diabetes mellitus is a chronic condition that occurs when the body cannot produce enough or effectively use of insulin.Compared with individuals without diabetes,patients with type 2 diabetes mellitus have a considerably higher risk of cardiovascular morbidity and mortality,and are disproportionately affected by cardiovascular disease.Most of this excess risk is it associated with an augmented prevalence of well-known risk factors such as hypertension,dyslipidaemia and obesity in these patients.However the improved cardiovascular disease in type 2 diabetes mellitus patients can not be attributed solely to the higher prevalence of traditional risk factors.Therefore other non-traditional risk factors may be important in people with type 2 diabetes mellitus.Cardiovascular disease is increased in type 2 diabetes mellitus subjects due to a complex combination of various traditional and non-traditional risk factors that have an important role to play in the beginning and the evolution of atherosclerosis over its long natural history from endothelial function to clinical events.Many of these risk factors could be common history for both di-abetes mellitus and cardiovascular disease,reinforcing the postulate that both disorders come independently from'common soil'.The objective of this review is to highlight the weight of traditional and non-traditional risk factors for cardiovascular disease in the setting of type 2 diabetes mellitus and discuss their position in the pathogenesis of the excess cardiovascular disease mortality and morbidity in these patients. | Iciar Martín-Timón Cristina Sevillano-Collantes Amparo Segura-Galindo Francisco Javier del Caizo-Gómez | 2014 | World Journal of Diabetes2014，5，4： | 32 |
| 12 | Metabolic syndrome as a risk factor for gallstone disease显示文摘AIM: To establish an association between the presence of metabolic syndrome and the development of gallstone disease.METHOIDS: We carried out a cross-sectional study in a check-up unit in a university hospital in Mexico City. We enrolled 245 subjects, comprising 65 subjects with gallstones (36 women, 29 men) and 180 controls (79women and 101 men without gallstones). Body mass index, waist circumference, blood pressure, plasma insulin, and serum lipids and lipoproteins levels were measured. Insulin resistance was calculated by homeostasis model assessment. Unconditional logistic regressionanalysis (univariate and multivariate) was used to calculate the risk of gallstone disease associated with the presence of at least three of the criteria (Adult Treatment Panel Ⅲ). Analyses were adjusted for age and sex.RESULTS: Among 245 subjects, metabolic syndrome was present in 40% of gallstone disease subjects, compared with 17.2% of the controls, adjusted by age and gender (odds ratio (OR) = 2.79; 95%CI, 1.46-5.33; P = 0.002),a dose-dependent effect was observed with each component of metabolic syndrome (OR = 2.36, 95%CI, 0.72-7.71;P = 0.16 with one component and OR = 5.54, 95%CI,1.35-22.74; P = 0.02 with four components of metabolic syndrome). Homeostasis model assessment was significantly associated with gallstone disease (adjusted OR = 2.25;95%CI, 1.08-4.69; P = 0.03).CONCLUSION: We conclude that as for cardiovascular disease and diabetes mellitus, gallstone disease appears to be strongly associated with metabolic syndrome. | Nahum Méndez-Sánchez Norberto C.

| 13 | Reactivation of hepatitis B virus infection after cytotoxic chemotherapy or immunosuppressive therapy显示文摘Reactivation of hepatitis B is defined as the recurrence or an abrupt rise in hepatitis B virus(HBV) replication,often accompanied by an increase in serum transaminase levels,and both events occurring in a patient with a previous inactive hepatitis B infection.This reactivation can occur in situations in which the ratio of HBV replication and immune response is altered.It can happen during the treatment of hemato-oncological malignancies with chemotherapy and in immunosuppression of autoimmune diseases.Clinical manifestations of hepatitis B reactivation are variable and can range from asymptomatic to acute hepatitis,which are sometimes serious and result in acute liver failure with risk of death,and usually occur in the periods between cycles or at the end of chemotherapy.Immunosuppressive drugs such as corticosteroids or azathioprine can induce HBV reactivation in patients carrying hepatitis B virus surface antigen(HBsAg) or anti-HBc,but much less frequently than chemotherapy treatments.The tumor necrosis factorαinhibitors infliximab,etanercept and adalimumab may cause reactivation of hepatitis B,and the overall frequency with infliximab may be similar(50%-66%) to that caused by chemotherapy.Baseline HBV serology is recommended for all patients receiving chemotherapy and immunosuppressive drugs,and HBsAg positive patients should receive anti-HBV prophylaxis to decrease virus reactivation and death rates. | María Luisa Manzano-Alonso Gregorio Castellano-Tortajada | 2011 | World Journal of Gastroenterology2011，17，12： | 31 |
| 14 | Complications of hip fractures: A review显示文摘Nowadays, fracture surgery represents a big part of the orthopedic surgeon workload, and usually has associated major clinical and social cost implications. These fractures have several complications. Some of these are medical, and other related to the surgical treatment itself. Medical complications may affect around 20% of patients with hip fracture. Cognitive and neurological alterations, cardiopulmonary affections(alone or combined), venous thromboembolism, gastrointestinal tract bleeding, urinary tract complications, perioperative anemia, electrolytic and metabolic disorders, and pressure scars are the most important medical complications after hip surgery in terms of frequency, increase of length of stay and perioperative mortality. Complications arising from hip fracture surgery are fairly common, and vary depending on whether the fracture is intracapsular or extracapsular. The main problems in intracapsular fractures are biological: vascularization of the femoral head, and lack of periosteum-a major contributor to fracture healing- in the femoral neck. In extracapsularfractures, by contrast, the problem is mechanical, and relates to load-bearing. Early surgical fixation, the role of anti-thromboembolic and anti-infective prophylaxis, good pain control at the perioperative, detection and management of delirium, correct urinary tract management, avoidance of malnutrition, vitamin D supplementation, osteoporosis treatment and advancement of early mobilization to improve functional recovery and falls prevention are basic recommendations for an optimal maintenance of hip fractured patients. | Pedro Carpintero Jose Ramón Caeiro Rocío Carpintero Angela Morales Samuel Silva Manuel Mesa | 2014 | World Journal of Orthopedics2014，5，4： | 31 |
| 15 | Short-term clinical outcomes of laparoscopic vs open rectal excision for rectal cancer: A systematic review and metaanalysis显示文摘AIM To review evidence on the short-term clinical outcomes of laparoscopic(LRR) vs open rectal resection(ORR) for rectal cancer.METHODS A systematic literature search was performed using Cochrane Central Register, MEDLINE, EMBASE, Scopus, Open Grey and Clinical Trials.gov register for randomized clinical trials(RCTs) comparing LRR vs ORR for rectal cancer and reporting short-term clinical outcomes. Articles published in English from January 1, 1995 to June, 30 2016 that met the selection criteria were retrieved and reviewed. The Preferred Reporting Items for Systematic reviews and Meta-Analysis(PRISMA) statements checklist for reporting a systematic review was followed. Random-effect models were used to estimate mean differences and risk ratios. The robustness and heterogeneity of the results were explored by performing sensitivity analyses. The pooledeffect was considered significant when P < 0.05.RESULTS Overall, 14 RCTs were included. No differences were found in postoperative mortality(P = 0.19) and morbidity(P = 0.75) rates. The mean operative time was 36.67 min longer(95%CI: 27.22-46.11, P < 0.00001), the mean estimated blood loss was 88.80 ml lower(95%CI:-117.25 to-60.34, P < 0.00001), and the mean incision length was 11.17 cm smaller(95%CI:-13.88 to-8.47, P < 0.00001) for LRR than ORR. These results were confirmed by sensitivity analyses that focused on the four major RCTs. The mean length of hospital stay was 1.71 d shorter(95%CI:-2.84 to-0.58, P < 0.003) for LRR than ORR. Similarly, bowel recovery(i.e., day of the first bowel movement) was 0.68 d shorter(95%CI:-1.00 to-0.36, P < 0.00001) for LRR. The sensitivity analysis did not confirm a significant difference between LRR and ORR for these latter two parameters. The overall quality of the evidence was rated as high. CONCLUSION LRR is associated with lesser blood loss, smaller incision length, and longer operative times compared to ORR. No differences are observed for postoperative morbidity and mortality. | Aleix Martínez-Pérez Maria Clotilde Carra Francesco Brunetti Nicola de'Angelis | 2017 | World Journal of Gastroenterology2017，23，44： | 33 |
| 16 | Comparative review of vertebroplasty and kyphoplasty显示文摘The aim of this review is to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain and improve functional outcome from ver-tebral fractures secondary to osteoporosis and tumor conditions. In 2009, two open randomized controlled trials published in the New England Journal of Medicine questioned the value of vertebroplasty in treating ver-tebral compression fractures. Nevertheless, the prac-tice of physicians treating these conditions has barely changed. The objective of this review is to try to clarify the most important issues, based on our own experi-ence and the reported evidence about both techniques, and to guide towards the most appropriate choice of treatment of vertebral fractures, although many ques-tions still remain unanswered. | Ferno Ruiz Santiago Alicia Santiago Chinchilla Luis Guzmán álvarez Antonio Luis Pérez Abela Maria del Mar Castellano García Miguel Pajares López | 2014 | World Journal of Radiology2014，6，6： | 30 |
| 17 | An overview of animal models for investigating the pathogenesis and therapeutic strategies in acute hepatic failure显示文摘Acute hepatic failure (AHF) is a severe liver injury accompanied by hepatic encephalopathy which causes multiorgan failure with an extremely high mortality rate, even if intensive care is provided. Management of severe AHF continues to be one of the most challenging problems in clinical medicine. Liver transplantation has been shown to be the most effective therapy, but the procedure is limited by shortage of donor organs. Although a number of clinical trials testing different liver assist devices are under way, these systems alone have no significant effect on patient survival and are only regarded as a useful approach to bridge patients with AHF to liver transplantation. As a result, reproducible experimental animal models resembling the clinical conditions are still needed. The three main approaches used to create an animal model for AHF are: surgical procedures, toxic liver injury and infective procedures. Most common models are based on surgical techniques (total/partial hepatectomy, complete/transient devascularization) or the use of hepatotoxic drugs (acetaminophen, galactosamine, thioacetamide, and others), and very few satisfactory viral models are available. We have recently developed a viral model of AHF by means of the inoculation of rabbits with the virus of rabbit hemorrhagic disease. This model displays biochemical and histological characteristics, and clinical features that resemble those in human AHF. In the present article an overview is given of the most widely used animal models of AHF, and their main advantages and disadvantages are reviewed. | María Jesús Tuón Marcelino Alvarez Jesús M Culebras Javier González-Gallego | 2009 | World Journal of Gastroenterology2009，15，25： | 29 |
| 18 | Endoscopic management of esophageal varices显示文摘The rupture of gastric varices results in variceal hemorrhage, which is one the most lethal complications of cirrhosis. Endoscopic therapies for varices aim to reduce variceal wall tension by obliteration of the varix. The two principal methods available for esophageal varices are endoscopic sclerotherapy (EST) and band ligation (EBL). The advantages of EST are that it is cheap and easy to use, and the injection catheter fits through the working channel of a diagnostic gastroscope. Endoscopic variceal ligation obliterates varices by causing mechanical strangulation with rubber bands. The following review aims to describe the utility of EBL and EST in different situations, such as acute bleeding, primary and secondary | Joaquin Poza Cordon Consuelo Froilan Torres Aurora Burgos García Francisco Gea Rodriguez Jose Manuel Suárez de Parga | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，7： | 27 |
| 19 | Risk factors associated with the development of ischemic colitis显示文摘AIM:To ascertain the role of cardiovascular risk factors,cardiovascular diseases,standard treatments and other diseases in the development of ischemic colitis(IC).METHODS:A retrospective,case-control study was designed,using matched data and covering 161 incident cases of IC who required admission to our hospital from 1998 through 2003.IC was diagnosed on the basis of endoscopic findings and diagnostic or compatible his-tology.Controls were randomly chosen from a cohort of patients who were admitted in the same period and required a colonoscopy,excluding those with diagnosis of colitis.Cases were matched with controls(ratio 1:2),by age and sex.A conditional logistic regression was performed.RESULTS:A total of 483 patients(161 cases,322 con-trols)were included;mean age 75.67±10.03 years,55.9%women.The principal indications for colonos-copy in the control group were lower gastrointestinal hemorrhage(35.4%),anemia(33.9%),abdominal pain(19.9%)and diarrhea(9.6%).The endoscopic findings in this group were hemorrhoids(25.5%),diverticular disease(30.4%),polyps(19.9%)and colorectal cancer(10.2%).The following variables were associated with IC in the univariate analysis:arterial hypertension(P= 0.033);dyslipidemia(P<0.001);diabetes mellitus(P =0.025);peripheral arterial disease(P=0.004);heart failure(P=0.026);treatment with hypotensive drugs(P=0.023);angiotensin-converting enzyme inhibitors;(P=0.018);calcium channel antagonists(P=0.028);and acetylsalicylic acid(ASA)(P<0.001).Finally,the following variables were independently associated with the development of IC:diabetes mellitus[odds ratio(OR)1.76,95%confidence interval(CI):1.001-3.077,P=0.046];dyslipidemia(OR 2.12,95%CI:1.26-3.57,P=0.004);heart failure(OR 3.17,95%CI:1.31-7.68,P=0.01);peripheral arterial disease(OR 4.1,95%CI:1.32-12.72,P=0.015);treatment with digoxin(digitalis)(OR 0.27,95%CI:0.084-0.857,P=0.026);and ASA(OR 1.97,95%CI:1.16-3.36,P=0.012).CONCLUSION:The development of an episode of IC was independently associated with diabetes,dyslipid-emia,presence of heart failure,peripheral arterial dis-ease and treatment with digoxin or ASA. | Joaquín Cubiella Fernández Luisa Núez Calvo Elvira González Vázquez Maria Jesús García García Maria Teresa Alves Pérez Isabel Martínez Silva Javier Fernández Seara | 2010 | World Journal of Gastroenterology2010，16，36： | 27 |
| 20 | Laparoscopic and robot-assisted laparoscopic digestivesurgery:Present and future directions显示文摘Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen's fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated. | Juan C Rodríguez-Sanjuán Marcos Gómez-Ruiz Soledad Trugeda-Carrera Carlos Manuel-Palazuelos Antonio López-Useros Manuel Gómez-Fleitas | 2016 | World Journal of Gastroenterology2016，22，6： | 27 |
