| 1 | Preoperative rectosigmoid endoscopic ultrasonography predicts the need for bowel resection in endometriosis显示文摘BACKGROUND Rectosigmoid endometriosis is an underdiagnosed disease responsible for abdominal pain, transit disorders and rectal bleeding. Two surgical approaches,rectosigmoid bowel resection(segmental or patch) or intramuscular layer dissection(shaving), are available.AIM To assess whether the lesion features observed via preoperative rectosigmoid endoscopic ultrasonography(RS-EUS) might predict the need for bowel resection.METHODS This multicentric retrospective study was conducted on patients with rectosigmoid endometriosis who underwent a curative surgical procedure,evaluated by RS-EUS performed by two trained operators, between January 2012 and March 2018. A univariate statistical analysis was performed on nodules' RSEUS features(thickness, width, infiltration of the submucosae, presence of a bump into the digestive lumen and presence of multiple rectosigmoid localizations). A multivariate logistic regression was then performed on the significant results.RESULTS Of the 367 patients, 73 patients with rectosigmoid endometriosis were evaluated by RS-EUS and underwent rectosigmoid surgery. After the univariate analysis was completed, thickness, width and infiltration of the submucosae were identified as potential predictive factors for bowel resection. In a multivariate logistic regression model, only thickness appeared to be a significant [odds ratio(OR) = 1.49, 95% confidence interval(CI): 1.04-2.12, P = 0.028] predictive factor for bowel resection. Receiver operating characteristic analysis performed showed that a thickness over 5.20 mm might be used as cut-off with a sensitivity of 76%, a specificity of 81%, and an area under carve = 0.82. The cut-off values for 100%sensitivity and 100% specificity were 0.90 mm and 10.00 mm, respectively. A trend concerning width to predict the need for resection was also observed(OR1.12, 95%CI: 1.00-1.26, P = 0.054)CONCLUSION The presence of a rectosigmoid nodule of endometriosis greater than 5.20 mm thick on RS-EUS might predict the need for bowel resection. | Victor Desplats René-Louis Vitte Joseph du Cheyron Gilles Roseau Arnaud Fauconnier Frédérick Moryoussef | 2019 | World Journal of Gastroenterology2019，25，6： | 9 |
| 2 | Clopidogrel and proton pump inhibitors-where do we stand in 2012?显示文摘Clopidogrel in association with aspirine is considered state of the art of medical treatment for acute coronary syndrome by reducing the risk of new ischemic events.Concomitant treatment with proton pump inhibitors in order to prevent gastrointestinal side effects is recommended by clinical guidelines.Clopidogrel needs metabolic activation predominantly by the hepatic cytochrome P450 isoenzyme Cytochrome 2C19(CYP2C19) and proton pump inhibitors(PPIs) are extensively metabolized by the CYP2C19 isoenzyme as well.Several pharmacodynamic studies investigating a potential clopidogrel-PPI interaction found a significant decrease of the clopidogrel platelet antiaggregation effect for omeprazole,but not for pantoprazole.Initial clinical cohort studies in 2009 reported an increased risk for adverse cardiovascular events,when under clopidogrel and PPI treatment at the same time.These observations led the United States Food and Drug Administration and the European Medecines Agency to discourage the combination of clopidogrel and PPI(especially omeprazole) in the same year.In contrast,more recent retrospective cohort studies including propensity score matching and the only existing randomized trial have not shown any difference concerning adverse cardiovascular events when concomitantly on clopidogrel and PPI or only on clopidogrel.Three meta-analyses report an inverse correlation between clopidogrel-PPI interaction and study quality,with high and moderate quality studies not reporting any association,rising concern about unmeasured confounders biasing the low quality studies.Thus,no definite evidence exists for an effect on mortality.Because PPI induced risk reduction clearly overweighs the possible adverse cardiovascular risk in patients with high risk of gastrointestinal bleeding,combination of clopidogrel with the less CYP2C19 inhibiting pantoprazole should be recommended. | Michael D Drepper Laurent Spahr Jean Louis Frossard | 2012 | World Journal of Gastroenterology2012，18，18： | 8 |
| 3 | Evaluation of Doppler-ultrasonography in the diagnosis of transjugular intrahepatic portosystemic shunt dysfunction: A prospective study显示文摘AIM To prospectively evaluate the performance of Dopplerultrasonography(US) for the detection of transjugular intrahepatic portosystemic shunt(TIPS) dysfunction within a multicenter cohort of cirrhotic patients.METHODS This study was conducted in 10 french teaching hospitals. After TIPS insertion, angiography and liver Doppler-US were carried out every six months to detect dysfunction(defined by a portosystemic gradient ≥ 12 mm Hg and/or a stent stenosis ≥ 50%). The association between ultrasonographic signs and dysfunction was studied by logistic random-effects models, and the diagnostic performance of each Doppler criterion was estimated by the bootstrap method. This study was approved by the ethics committee of Tours.RESULTS Two hundred and eighteen pairs of examinations performed on 87 cirrhotic patients were analyzed. Variables significantly associated with dysfunction were: The speed of flow in the portal vein(P = 0.008), the reversal of flow in the right(P = 0.038) and left(P = 0.049) portal branch, the loss of modulation of portal flow by the right atrium(P = 0.0005), ascites(P = 0.001) and the overall impression of the operator(P = 0.0001). The diagnostic performances of these variables were low; sensitivity was < 58% and negative predictive value was < 73%. Therefore, dysfunction cannot be ruled out from Doppler-US. CONCLUSION The performance of Doppler-US for the detection of TIPS dysfunction is poor compared to angiography. New tools are needed to improve diagnosis of TIPS dysfunction. | Charlotte Nicolas Amelie Le Gouge Louis d’Alteroche Jean Ayoub Monica Georgescu Vincent Vidal Denis Castaing Jean-Pierre Cercueil Patrick Chevallier Jerome Roumy Herve Trillaud Louis Boyer Vincent Le Pennec Christophe Perret Bruno Giraudeau Jean-Marc Perarnau STIC-TIPS group | 2017 | World Journal of Hepatology2017，9，27： | 6 |

| 7 | Ron receptor-dependent gene regulation in a mouse model of endotoxin-induced acute liver failure显示文摘BACKGROUND:Prior experimentation has shown that loss of the tyrosine kinase(TK) signaling domain of the Ron receptor leads to marked hepatocyte protection in a model of lipopolysaccharideinduced acute liver failure(ALF) in D-galactosamine(GalN)sensitized mice.The aim of this study was to identify the role of Ron in the regulation of hepatic gene expression.METHODS:Microarray analyses were performed on liver RNA isolated sequentially from wild-type(WT) and TK-/mice during the progression of ALF.Gene array data were validated using Western and immunohistochemistry analyses as well as with ex vivo culture systems.RESULTS:At baseline,101 genes were differentially expressed between WT and TK-/-livers,which regulate processes involved in hypoxia,proliferation,apoptosis and metabolism.One hour after ALF induction,WT livers exhibited increased cytokine expression compared to TK-/-livers,and after 4 hours,an induction of suppressor of cytokine signaling(SOCS) genes as well as JAK-STAT pathway activation were prominent in TK-/livers compared to controls.CONCLUSION:Our studies suggest a novel hepato-protective mechanism in Ron TK-/-mice wherein increased and sustained SOCS production and JAK-STAT activation in the hepatocyte may inhibit the destructive proinflammatory milieu and promote survival factors which blunt hepatic death and the ensuing development of ALF. | Rishikesh M Kulkarni Louis W Kutcher William D Stuart Daniel J Carson Mike A Leonis Susan E Waltz | 2012 | Hepatobiliary & Pancreatic Diseases International2012，11，4： | 3 |

| 10 | Role of endoscopic ultrasound in the screening and follow-up of high-risk individuals for familial pancreatic cancer显示文摘Managing familial pancreatic cancer(FPC)is challenging for gastroenterologists,surgeons and oncologists.High-risk individuals(HRI)for pancreatic cancer(PC)(FPC or with germline mutations)are a heterogeneous group of subjects with a theoretical lifetime cumulative risk of PC over 5%.Screening is mainly based on annual magnetic resonance imaging(MRI)and endoscopic ultrasound(EUS).The goal of screening is to identify early-stage operable cancers or high-risk precancerous lesions(pancreatic intraepithelial neoplasia or intraductal papillary mucinous neoplasms with high-grade dysplasia).In the literature,target lesions are identified in 2%-5%of HRI who undergo screening.EUS appears to provide better identification of small solid lesions(0%-46%of HRI)and chronicpancreatitis-like parenchymal changes(14%-77%of HRI),while MRI is probably the best modality to identify small cystic lesions(13%-49%of HRI).There are no specific studies in HRI on the use of contrast-enhanced harmonic EUS.EUS can also be used to obtain tissue samples.Nevertheless,there is still limited evidence on the accuracy of imaging procedures used for screening or agreement on which patients to treat.The cost-effectiveness of screening is also unclear.Certain new EUS-related techniques,such as searching for DNA abnormalities or protein markers in pancreatic fluid,appear to be promising. | Diane Lorenzo Vinciane Rebours Frédérique Maire Maxime Palazzo Jean-Michel Gonzalez Marie-Pierre Vullierme Alain Aubert Pascal Hammel Philippe Lévy Louis de Mestier | 2019 | World Journal of Gastroenterology2019，25，34： | 2 |
