BACKGROUND Healing of mucosal lesions appears to offer significant benefit and is an important end point in clinical trials of treatment for Crohn's disease. The only validated endoscopic activity score at present is the Crohn's Disease Endoscopic Index of Severity, which is complicated and time consuming and, hence, is unsuitable for routine use. The aim(More)
BACKGROUND Extreme obesity increases morbi-mortality in bariatric surgery. We previously showed that significant weight loss can be obtained within 3 months in super-super obese patients (BMI > 60 kg/m(2)) with an intragastric balloon (IGB). Here, we explored the potential benefit of preoperative IGB on the outcome of laparoscopic gastric bypass (LGBP) in(More)
BACKGROUND & AIMS Adherent-invasive Escherichia coli (AIEC) pathovar has been identified in the intestinal mucosa of patients with Crohn's disease (CD). AIEC reference strain LF82 is able to adhere to intestinal epithelial cells, to invade epithelial cells via a mechanism involving actin polymerization and microtubules, and to survive and replicate within(More)
5-aminosalicylic acid (5-ASA) is an antiinflammatory drug widely used in the treatment of inflammatory bowel diseases. It is known to inhibit the production of cytokines and inflammatory mediators, but the mechanism underlying the intestinal effects of 5-ASA remains unknown. Based on the common activities of peroxisome proliferator-activated receptor-gamma(More)
UNLABELLED Transjugular intrahepatic portosystemic shunt (TIPS) is a more effective treatment for refractory ascites than large volume paracentesis (LVP), but the magnitude of its effect in terms of control of ascites, encephalopathy and survival has not been established. AIM This meta-analysis compare TIPS to LVP in terms of control of ascites at 4 and(More)
BACKGROUND AND AIMS Following ileocolonic resection for Crohn's disease (CD), early endoscopic recurrence predicts recurrence of symptoms. The aim of the study was to compare ileocolonoscopy and wireless capsule endoscopy (WCE) for the detection of postoperative recurrence in CD. METHODS WCE and ileocolonoscopy were performed within six months following(More)
BACKGROUND No study on bioclinical criteria predicting a biliary origin for acute pancreatitis has included endosonography as a reference examination. Re-examination of bioclinical parameters deserves consideration in the era where other causes are known (e.g. hereditary, autoimmune). AIM AND METHODS To determine the performance of bioclinical markers in(More)
BACKGROUND AND AIMS Recent studies with mu opioid receptor (MOR) deficient mice support a physiological anti-inflammatory effect of MOR at the colon interface. To better understand the potential pharmacological effect of certain opiates in inflammatory bowel diseases (IBD), we (1) evaluated the regulation in vivo and in vitro of human MOR expression by(More)
BACKGROUND The pathogenesis of Crohn's disease (CD) involved microbial factors. Some Helicobacter species, the so-called entero-hepatic Helicobacters (EHH), can naturally colonize the intestinal surface and have been detected in humans. Aim To look for an association between CD and the presence of EHH DNA in intestinal biopsies. METHODS Two groups of(More)
The purpose of this study was to assess the usefulness of helical CT in depicting the location of acute lower gastrointestinal bleeding. A three-phase helical CT of the abdomen was performed in 24 patients referred for acute lower gastrointestinal bleeding. The diagnosis of the bleeding site was established by CT when there was at least one of the following(More)
