| 1 | Transjugular intrahepatic portosystemic shunt for the management of acute variceal hemorrhage显示文摘Acute variceal hemorrhage,a life-threatening condition that requires a multidisciplinary approach for effective therapy,is defined as visible bleeding from an esophageal or gastric varix at the time of endoscopy,the presence of large esophageal varices with recent stigmata of bleeding,or fresh blood visible in the stomach with no other source of bleeding identified.Transfusion of blood products,pharmacological treatments and early endoscopic therapy are often effective;however,if primary hemostasis cannot be obtained or if uncontrollable early rebleeding occurs,transjugular intrahepatic portosystemic shunt(TIPS)is recommended as rescue treatment.The TIPS represents a major advance in the treatment of complications of portal hypertension.Acute variceal hemorrhage that is poorly controlled with endoscopic therapy is generally well controlled with TIPS,which has a 90%to 100%success rate.However,TIPS is associated with a mortality of 30%to 50%in such a setting.Emergency TIPS should be considered early in patients with refractory variceal bleeding once medical treatment and endoscopic sclerotherapy failure,before the clinical condition worsens.Furthermore,admission to specialized centers is mandatory in such a setting and regional protocols are essential to be organized effectively.This review article discusses initial management and then focuses on the specific role of TIPS as a primary therapy to control acute variceal hemorrhage,particularly as a rescue therapy following failure of endoscopic approaches. | Romaric Loffroy Louis Estivalet Violaine Cherblanc Sylvain Favelier Pierre Pottecher Samia Hamza Anne Minello Patrick Hillon Pierre Thouant Pierre-Henri Lefevre Denis Krausé Jean-Pierre Cercueil | 2013 | World Journal of Gastroenterology2013，19，37： | 25 |
| 2 | Colon cancer-associated B2 Escherichia coli colonize gut mucosa and promote cell proliferation显示文摘AIM:To provide further insight into the characterization of mucosa-associated Escherichia coli(E.coli)isolated from the colonic mucosa of cancer patients.METHODS:Phylogroups and the presence of cyclomodulin-encoding genes of mucosa-associated E.coli from colon cancer and diverticulosis specimens weredetermined by PCR.Adhesion and invasion experiments were performed with I-407 intestinal epithelial cells using gentamicin protection assay.Carcinoembryonic antigen-related cell adhesion molecule 6(CEACAM6)expression in T84 intestinal epithelial cells was measured by enzyme-linked immunosorbent assay and by Western Blot.Gut colonization,inflammation and procarcinogenic potential were assessed in a chronic infection model using CEABAC10 transgenic mice.Cell proliferation was analyzed by real-time mRNA quantification of PCNA and immunohistochemistry staining of Ki67.RESULTS:Analysis of mucosa-associated E.coli from colon cancer and diverticulosis specimens showed that whatever the origin of the E.coli strains,86%of cyclomodulin-positive E.coli belonged to B2 phylogroup and most harbored polyketide synthase(pks)island,which encodes colibactin,and/or cytotoxic necrotizing factor(cnf)genes.In vitro assays using I-407 intestinal epithelial cells revealed that mucosa-associated B2 E.coli strains were poorly adherent and invasive.However,mucosa-associated B2 E.coli similarly to Crohn’s disease-associated E.coli are able to induce CEACAM6expression in T84 intestinal epithelial cells.In addition,in vivo experiments using a chronic infection model of CEACAM6 expressing mice showed that B2 E.coli strain11G5 isolated from colon cancer is able to highly persist in the gut,and to induce colon inflammation,epithelial damages and cell proliferation.CONCLUSION:In conclusion,these data bring new insights into the ability of E.coli isolated from patients with colon cancer to establish persistent colonization,exacerbate inflammation and trigger carcinogenesis. | Jennifer Raisch Emmanuel Buc Mathilde Bonnet Pierre Sauvanet Emilie Vazeille Amélie de Vallée Pierre Déchelotte Claude Darcha Denis Pezet Richard Bonnet Marie-Agnès Bringer Arlette Darfeuille-Michaud | 2014 | World Journal of Gastroenterology2014，20，21： | 12 |
| 3 | Endovascular management of visceral artery aneurysms: When to watch, when to intervene?显示文摘Visceral artery aneurysms(VAA) include splanchnic and renal artery aneurysms. They represent a rare clinical entity, although their detection is rising due to an increased use of cross-sectional imaging. Rupture is the most devastating complication, and is associated with a high morbidity and mortality. In addition, increased percutaneous endovascular interventions have raised the incidence of iatrogenic visceral artery pseudoaneurysms(VAPAs). For this reason, elective repair is preferable in the appropriately chosen patient. Controversy still exists regarding their treatment. Over the past decade, there has been steady increase in the utilization of minimally invasive, non-operative interventions, for vascular aneurysmal disease. All VAAs and VAPAs can technically be fixed by endovascular techniques but that does not mean they should. These catheter-based techniques constitute an excellent approach in the elective setting. However, in the emergent setting it may carry a higher morbidity and mortality. The decision for intervention has to take into account the size and the natural history of the lesion, the risk of rupture, which is high during pregnancy, and the relative risk of surgical or radiological intervention. For splanchnic artery aneurysms, we should recognize that we are not, in reality, well informed about their natural history. For most asymptomatic aneurysms, expectant treatment is acceptable. For large, symptomatic or aneurysms with a high risk of rupture, endovascular treatment has become the firstline therapy. Treatment of VAPAs is always mandatory because of the high risk of rupture. We present our point of view on interventional radiology in the splanchnic arteries, focusing on what has been achieved and the remaining challenges. | Romaric Loffroy Sylvain Favelier Pierre Pottecher Pierre-Yves Genson Louis Estivalet Sophie Gehin Jean-Pierre Cercueil Denis Krausé | 2015 | World Journal of Radiology2015，7，7： | 11 |
| 4 | Association of colorectal cancer with pathogenic Escherichia coli: Focus on mechanisms using optical imaging显示文摘AIM: To investigate the molecular or cellular mechanisms related to the infection of epithelial colonic mucosa by pks-positive Escherichia coli(E. coli) using optical imaging.METHODS: We choose to evaluate the tumor metabolic activity using a fluorodeoxyglucose analogue as 2-deoxyglucosone fluorescent probes and to correlate it with tumoral volume(mm^3). Inflammation measuring myeloperoxidase(MPO) activity and reactive oxygen species production was monitored by a bioluminescent(BLI) inflammation probe and related to histological examination and MPO levels by enzyme-linked immunosorbent assay(ELISA) on tumor specimens. The detection and quantitation of these two signals were validated on a xenograft model of human colon adenocarcinoma epithelial cells(HCT116) in nude mice infected with a pks-positive E. coli. The inflammatory BLI signal was validated intra-digestively in the colitisCEABAC10 DSS models, which mimicked Crohn's disease. RESULTS: Using a 2-deoxyglucosone fluorescent probe, we observed a high and specific HCT116 tumor uptake in correlation with tumoral volume(P = 0.0036). Using the inflammation probe targeting MPO, we detected a rapid systemic elimination and a significant increase of the BLI signal in the pks-positive E. coli-infected HCT116 xenograft group(P < 0.005). ELISA confirmed that MPO levels were significantly higher(1556 ± 313.6 vs 234.6 ± 121.6 ng/m L P = 0.001) in xenografts infected with the pathogenic E. coli strain. Moreover, histological examination of tumor samples confirmed massive infiltration of pks-positive E. coli-infected HCT116 tumors by inflammatory cells compared to the uninfected group. These data showed that infection with the pathogenic E. coli strain enhanced inflammation and ROS production in tumors before tumor growth. Moreover, we demonstrated that the intra-digestive monitoring of inflammation is feasible in a reference colitis murine model(CEABAC10/DSS).CONCLUSION: Using BLI and fluorescence optical imaging, we provided tools to better understand hostpathogen interactions at the early stage of disease, such as inflammatory bowel disease and colorectal cancer. | Julie Veziant Johan Gagnière Elodie Jouberton Virginie Bonnin Pierre Sauvanet Denis Pezet Nicolas Barnich Elisabeth Miot-Noirault Mathilde Bonnet | 2016 | World Journal of Clinical Oncology2016，7，3： | 10 |

| 6 | Endoscopy-based management decreases the risk of postoperative recurrences in Crohn's disease显示文摘AIM: To investigate whether an endoscopy-based management could prevent the long-term risk of postoperative recurrence.METHODS: From the pathology department database, we retrospectively retrieved the data of all the patients operated on for Crohn's disease(CD) in our center(1986-2015). Endoscopy-based management was defined as systematic postoperative colonoscopy(median time after surgery = 9.5 mo) in patients with no clinical postoperative recurrence at the time of endoscopy. RESULTS: From 205 patients who underwent surgery, 161 patients(follow-up > 6 mo) were included. Endoscopic postoperative recurrence occurred in 67.6%, 79.7%, and 95.5% of the patients, respectively 5, 10 and 20 years after surgery. The rate of clinical postoperative recurrence was 61.4%, 75.9%, and 92.5% at 5, 10 and 20 years, respectively. The rate of surgical postoperative recurrence was 19.0%, 38.9% and 64.7%, respectively, 5, 10 and 20 years after surgery. In multivariate analysis, previous intestinal resection, prior exposure to anti-TNF therapy before surgery, and fistulizing phenotype(B3) were postoperative risk factors. Previous perianal abscess/fistula(other perianal lesions excluded), were predictive of only symptomatic recurrence. In multivariate analysis, an endoscopy-based management(n = 49/161) prevented clinical(HR = 0.4, 95%CI: 0.25-0.66, P < 0.001) and surgical postoperative recurrence(HR = 0.30, 95%CI: 0.13-0.70, P = 0.006).CONCLUSION: Endoscopy-based management should be recommended in all CD patients within the first year after surgery as it highly decreases the long-term risk of clinical recurrence and reoperation. | Anne-Laure Boucher Bruno Pereira Stéphanie Decousus Marion Goutte Felix Goutorbe Anne Dubois Johan Gagniere Corinne Borderon Juliette Joubert Denis Pezet Michel Dapoigny Pierre J Déchelotte Gilles Bommelaer Anthony Buisson | 2016 | World Journal of Gastroenterology2016，22，21： | 3 |

| 12 | Macro-or microencapsulation of pig islets to cure type 1 diabetes显示文摘Although allogeneic islet transplantation can successfully cure type 1 diabetes,it has limited applicability.For example,organs are in short supply;several human pancreas donors are often needed to treat one diabetic recipient;the intrahepatic site may not be the most appropriate site for islet implantation;and immunosuppressive regimens,which are associated with side effects,are often required to prolong survival of the islet graft.An alternative source of insulinproducing cells would therefore be of major interest.Pigs represent a possible alternative source of beta cells.Grafting of pig islets may appear difficult because of the immunologic species barrier,but pig islets have been shown to function in primates for at least 6 mo with clinically incompatible immunosuppression.Therefore,a bioartificial pancreas made of encapsulated pig islets may resolve issues associated with islet allotransplantation.Although several groups have shown that encapsulated pig islets are functional in small-animal models,less is known about the use of bioartificial pancreases in large-animal models.In this review,we summarize current knowledge of encapsulated pig islets,to determine obstacles to implantation in humans and possible solutions to overcome these obstacles. | Denis Dufrane Pierre Gianello | 2012 | World Journal of Gastroenterology2012，18，47： | 2 |
