| 1 | Portal vein thrombosis:Insight into physiopathology,diagnosis,and treatment显示文摘Portal vein thrombosis (PVT) is a relatively common complication in patients with liver cirrhosis, but might also occur in absence of an overt liver disease. Several causes, either local or systemic, might play an important role in PVT pathogenesis. Frequently, more than one risk factor could be identified; however, occasionally no single factor is discernable. Clinical examination, laboratory investigations, and imaging are helpful to provide a quick diagnosis, as prompt treatment might greatly affect a patient's outcome. In this review, we analyze the physiopathological mechanisms of PVT development, together with the hemodynamic and functional alterations related to this condition. Moreover, we describe the principal factors most frequently involved in PVT development and the recent knowledge concerning diagnostic and therapeutic procedures. Finally, we analyze the implications of PVT in the setting of liver transplantation and its possible influence on patients' future prognoses. | Francesca R Ponziani Maria A Zocco Chiara Campanale Emanuele Rinninella Annalisa Tortora Luca Di Maurizio Giuseppe Bombardieri Raimondo De Cristofaro Anna M De Gaetano Raffaele Landolfi Antonio Gasbarrini | 2010 | World Journal of Gastroenterology2010，16，2： | 75 |
| 2 | Pancreatic neuroendocrine neoplasms: Magnetic resonance imaging features according to grade and stage显示文摘AIM To describe magnetic resonance(MR) imaging features of pancreatic neuroendocrine neoplasms(Pan NENs) according to their grade and tumor-nodes-metastases stage by comparing them to histopathology and todetermine the accuracy of MR imaging features in predicting their biological behavior.METHODS This study was approved by our institutional review board; requirement for informed patient consent was waived due to the retrospective nature of the study. Preoperative MR examinations of 55 Pan NEN patients(29 men, 26 women; mean age of 57.6 years, range 21-83 years) performed between June 2013 and December 2015 were reviewed. Qualitative and quantitative features were compared between tumor grades and stages determined by histopathological analysis.RESULTS Ill defined margins were more common in G2-3 and stage Ⅲ-Ⅳ PanN ENs than in G1 and low-stage tumors(P < 0.001); this feature had high specificity in the identification of G2-3 and stage Ⅲ-Ⅳ tumors(90.3% and 96%, 95%CI: 73.1-97.5 and 77.7-99.8). The mean apparent diffusion coefficient value was significantly lower in G2-3 and stage Ⅲ-Ⅳ lesions compared to well differentiated and low-stage tumors(1.09 × 10-3 mm2/s vs 1.45 × 10-3 mm2/s and 1.10 × 10-3 mm2/s vs 1.53 × 10-3 mm2/s, P = 0.003 and 0.001). Receiving operator characteristic analysis determined optimal cutoffs of 1.21 and 1.28 × 10-3 mm2/s for the identification of G2-3 and stage Ⅲ-Ⅳ tumors, with sensitivity and specificity values of 70.8/80.7% and 64.5/64%(95%CI: 48.7-86.6/60-92.7 and 45.4-80.2/42.6-81.3).CONCLUSION MR features of PanN ENs vary according to their grade of differentiation and their stage at diagnosis and could predict the biological behavior of these tumors. | Riccardo De Robertis Sara Cingarlini Paolo Tinazzi Martini Silvia Ortolani Giovanni Butturini Luca Landoni Paolo Regi Roberto Girelli Paola Capelli Stefano Gobbo Giampaolo Tortora Aldo Scarpa Paolo Pederzoli Mirko D'Onofrio | 2017 | World Journal of Gastroenterology2017，23，2： | 16 |
| 3 | Intermediate hepatocellular carcinoma: How to choose the best treatment modality?显示文摘Intermediate stage, or stage B according to Barcelona Clinic Liver Cancer classification, of hepatocellular carcinoma(HCC) comprises a heterogeneous population with different tumor burden and liver function. This heterogeneity is confirmed by the large variability of treatment choice and disease-relate survival. The aim of this review was to highlight the existing evidences regarding this specific topic. In a multidisciplinary evaluation, patients with large(> 5 cm) solitary HCC should be firstly considered for liver resection(LR). When LR is unfeasible, locoregional treatments are evaluable therapeutic options, being transarterial chemoembolization(TACE), the most used procedure. Percutaneous ablation can be an evaluable treatment for large HCC. However, the efficacy of all ablative procedures decrease as tumor size increases over 3 cm. In clinical practice, a combination treatment strategy [TACE or transarterial radioembolization(TARE)-plus percutaneous ablation] is 'a priori' preferred in a relevant percentage of these patients. On the other hands, sorafenib is the treatment of choice in patients who are unsuitable to surgery and/or with a contraindication to locoregional treatments. In multifocal HCC, TACE is the first-line treatment. The role of TARE is still undefined. Surgery may have also a role in the treatment of multifocal HCC in selected cases(patients with up to three nodules, multifocal HCC involving 2-3 adjacent liver segments). In some patients with bilobar disease the combination of LR and ablative treatment may be a valuable option. The choice of the best treatment in the patient with intermediate stage HCC should be 'patient-tailored' and made by a multidisciplinary team. | Giovan Giuseppe Di Costanzo Raffaella Tortora | 2015 | World Journal of Hepatology2015，7，9： | 12 |
| 4 | Role of Helicobacter pylori infection on nutrition and metabolism显示文摘Helicobacter pylori(H. pylori) is a gram-negative pathogen that is widespread all over the world, infecting more than 50% of the world's population. It is etiologically associated with non-atrophic and atrophic gastritis, peptic ulcer and shows a deep association with primary gastric B-cell lymphoma and gastric adenocarcinoma. Recently, the medical research focused on the modification of the gastric environment induced by H. pylori infection, possibly affecting the absorption of nutrients and drugs as well as the production of hormones strongly implicated in the regulation of appetite and growth. Interestingly, the absorption of iron and vitamin B12 is impaired by H. pylori infection, while infected subjects have lower basal and fasting serum levels of ghrelin and higher concentration of leptin compared to controls. Since leptin is an anorexigenic hormone, and ghrelin stimulates powerfully the release of growth hormone in humans, H. pylori infection may finally induce growth retardation if acquired very early in the childhood and in malnourished children. This review is focused on the nutritional effects of H. pylori infection, such as the reduced bioavailability or the malabsorbption of essential nutrients, and of gastrointestinal hormones, as well as on the relationship between H. pylori and the metabolic syndrome. | Francesco Franceschi Tortora Annalisa Di Rienzo Teresa D'Angelo Giovanna Gianluca Ianiro Scaldaferri Franco Gerardi Viviana Tesori Valentina Lopetuso Loris Riccardo Gasbarrini Antonio | 2014 | World Journal of Gastroenterology2014，20，36： | 11 |
| 5 | Prognostication and response assessment in liver and pancreatic tumors:The new imaging显示文摘Diffusion-weighted imaging(DWI), dynamic contrastenhanced magnetic resonance imaging(DCE-MRI) and perfusion computed tomography(CT) are technical improvements of morphologic imaging that can evaluate functional properties of hepato-bilio-pancreatic tumors during conventional MRI or CT examinations.Nevertheless, the term 'functional imaging' is commonly used to describe molecular imaging techniques, as positron emission tomography(PET)CT/MRI, which still represent the most widely used methods for the evaluation of functional properties of solid neoplasms; unlike PET or single photon emission computed tomography, functional imaging techniques applied to conventional MRI/CT examinations do not require the administration of radiolabeled drugs or specific equipments. Moreover, DWI and DCE-MRI can be performed during the same session, thus providing a comprehensive 'one-step' morphological and functional evaluation of hepato-bilio-pancreatic tumors. Literature data reveal that functional imaging techniques could be proposed for the evaluation of these tumors before treatment, given that they may improve staging and predict prognosis or clinical outcome. Microscopic changes within neoplastic tissues induced by treatments can be detected and quantified with functional imaging,therefore these techniques could be used also for posttreatment assessment, even at an early stage. The aim of this editorial is to describe possible applications of new functional imaging techniques apart frommolecular imaging to hepatic and pancreatic tumors through a review of up-to-date literature data, with a particular emphasis on pathological correlations,prognostic stratification and post-treatment monitoring. | Riccardo De Robertis Paolo Tinazzi Martini Emanuele Demozzi Gino Puntel Silvia Ortolani Sara Cingarlini Andrea Ruzzenente Alfredo Guglielmi Giampaolo Tortora Claudio Bassi Paolo Pederzoli Mirko D'Onofrio | 2015 | World Journal of Gastroenterology2015，21，22： | 10 |

| 7 | Efficacy and safety of endoscopic papillary balloon dilation for the removal of bile duct stones: Data from a “real-life” multicenter study on Dilation-Assisted Stone Extraction显示文摘AIM To report data on Dilation-Assisted Stone Extraction(DASE) use in clinical practice and its efficacy and safety trough three Italian referral centers for biliopancreatic diseases treatment. METHODS From January 2011 to December 2015 we collected data on 120 patients treated with DASE. Technical success was obtained when the endoscopist was able to place the balloon trough the papilla inflating the balloon until the final diameter for an adequate time(at least 30 s). Clinical success was obtained after complete stone removal(no remaining stones were visible at the cholangiogram).RESULTS Forty-nine male(40.8%) and 71 female(59%) were enrolled. The mean age was 67.8 years ± 15.7. The mean common bile duct(CBD) dilation was 19.2 mm± 3.9 and the mean size of stones 15.8 ± 2.9. DASE was applied as first approach in 38%(62% after initial failure of stones extraction). Technical and clinical success was of 91% and 87% respectively. In those in which DASE failed alternative treatment were adopted. After DASE 18% of patients experienced a complication(bleeding 9%, pancreatitis 8%, perforation 0.8%). At univariable analysis, elective endoscopic retrograde cholangiopancreatography(P = 0.031), DASE as first approach(P = 0.032), and cannulation of major papilla followed by guidewire insertion(P = 0.004) were related to low risk of complications. Pre-cut was related to an increased risk of complications(P = 0.01). CONCLUSION DASE allowed a higher first-session success rate and can be consider a valid alternative to endoscopic sphincterotomy not only for bigger CBD stones. | Roberto Di Mitri Filippo Mocciaro Socrate Pallio Giulia Maria Pecoraro Andrea Tortora Claudio Zulli Simona Attardo Attilio Maurano | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，18： | 3 |
| 8 | Fecal calprotectin in coeliac disease显示文摘We would like to share with the readers the results of our experience in 50 celiac disease(CD)patients,enrolled between September 2012 and April 2013,who were referred to our third-level CD Unit.The fecal calprotectin(FC)concentration of 50 adults with newly diagnosed CD was compared to that of a control group of 50 healthy subjects.FC level was determined by enzyme linked immunosorbent assay with diagnostic cutoff of 75μg/g.In addition,we tried to correlate the FC level with symptoms,histological severity of CD(Marsh grade)and level of tissue transglutaminase antibodies(aTg)in CD patients.Finally,FC level was increased in five CD patients and in four controls(10%vs 8%,P=NS);mean FC concentration of patients and controls were 57.7(SD±29.1)and 45.1(SD±38.4)respectively.Furthermore,no significant correlation was seen between FC levels and symptoms/Marsh grade/aTg.The five CD patients did not show inflammatory lesions(e.g.,ulcers,erosions)at upper endoscopy.The four healthy controls with positive FC were followed-up for further six months;in this observational period they did not show clinical signs of any underlying disease.On these bases,we think that FC is not able to investigate the subclinical inflammatory changes of active CD and FC should be considered a useless tool in the diagnostic work-up of uncomplicated CD but it should be accompanied by aTg when ruling out organic disease in patients with irritable bowel syndrome. | Pietro Capone Antonio Rispo Nicola Imperatore Nicola Caporaso Raffaella Tortora | 2014 | World Journal of Gastroenterology2014，20，2： | 3 |
| 9 | Management of single pulmonary metastases from colorectal cancer:State of the art显示文摘Colorectal cancer(CRC)is one of the most common causes of death from cancer.Lung seeding occurs in approximately 10%of patients surgically treated for primary CRC with radical intent:the lung is the most common site of metastases after the liver.While surgical treatment of liver metastases is widely accepted to affect long-term outcomes,more controversial and not standardized is the therapy for CRC patients developing lung metastases.Experience suggests the potential curative role of pulmonary metastasectomy,especially in oligometastatic disease.However,the optimal strategy of care and the definition of prognostic factors after treatment still need to be defined.This review focused on the uncommon scenario of single pulmonary metastases from CRC.We explored pertinent literature and provide an overview of the epidemiology,clinical characteristics and imaging of single pulmonary metastases from CRC.Additionally,we identified the best available evidence for overall management.In particular,we analyzed the role and results of locoregional approaches(surgery,radiotherapy or ablative procedures)and their integration with systemic therapy. | Marco Chiappetta Lisa Salvatore Maria Teresa Congedo Maria Bensi Viola De Luca Leonardo PetraccaCiavarella Floriana Camarda Jessica Evangelista Vincenzo Valentini Giampaolo Tortora StefanoMargaritora Filippo Lococo | 2022 | World Journal of Gastrointestinal Oncology2022，14，4： | 2 |

| 14 | Metastatic pancreatic cancer: Is there a light at the end of the tunnel?显示文摘Due to extremely poor prognosis,pancreatic cancer(PDAC)represents the fourth leading cause of cancerrelated death in Western countries.For more than a decade,gemcitabine(Gem)has been the mainstay of first-line PDAC treatment.Many efforts aimed at improving single-agent Gem efficacy by either combining it with a second cytotoxic/molecularly targeted agent or pharmacokinetic modulation provided disappointing results.Recently,the field of systemic therapy of advanced PDAC is finally moving forward.Polychemotherapy has shown promise over single-agent Gem:regimens like PEFG-PEXG-PDXG and GTX provide significant potential advantages in terms of survival and/or disease control,although sometimes at the cost of poor tolerability.The PRODIGE 4/ACCORD 11 was the first phaseⅢtrial to provide unequivocal benefit using the polychemotherapy regimen FOLFIRINOX;however the less favorable safety profile and the characteristics of the enrolled population,restrict the use of FOLFIRINOX to young and fit PDAC patients.The nanoparticle albumin-bound paclitaxel(nab-Paclitaxel)formulation was developed to overcome resistance due to the desmoplastic stroma surrounding pancreatic cancer cells.Regardless of whether or not this is its main mechanisms of action,the combination of nabPaclitaxel plus Gem showed a statistically and clinically significant survival advantage over single agent Gem and significantly improved all the secondary endpoints.Furthermore,recent findings on maintenance therapy are opening up potential new avenues in the treatment of advanced PDAC,particularly in a new era in which highly effective first-line regimens allow patients to experience prolonged disease control.Here,we provide an overview of recent advances in the systemic treatment of advanced PDAC,mostly focusing on recent findings that have set new standards in metastatic disease.Potential avenues for further development in the metastatic setting and current efforts to integratenew effective chemotherapy regimens in earlier stages of disease(neoadjuvant,adjuvant,and multimodal approaches in both resectable and unresectable patients)are also briefly discussed. | Vanja Vaccaro Isabella Sperduti Sabrina Vari Emilio Bria Davide Melisi Carlo Garufi Carmen Nuzzo Aldo Scarpa Giampaolo Tortora Francesco Cognetti Michele Reni Michele Milella | 2015 | World Journal of Gastroenterology2015，21，16： | 2 |
