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)
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)
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)
OBJECTIVE Bacterial agents have been implicated in the early recurrence of Crohn's disease after ileocolectomy. The aim of our study was to identify and quantify bacteria associated with the ileal mucosa in patients and controls and to correlate specific bacteria with recurrence. METHODS The predominant bacterial microflora of the ileum were enumerated(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)
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 Mucosal lesions of pouchitis are characterized by a neutrophil infiltrate. Interleukin (IL)-8 is the main mediator involved in neutrophil recruitment and is down-regulated by IL-10. AIM To look for an imbalance between IL-8 and IL-10 in patients with pouchitis. PATIENTS/METHODS 18 patients having an ileoanal pouch for ulcerative colitis were(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)
