The Montreal classification has been widely used in Crohn's disease since 2005 to categorize patients by the age of onset (A), location (L), behavior (B), and upper gastrointestinal tract perianal involvement. With evolving management paradigms disease, we aimed assess performance gastroenterologists applying classification. An online survey was conducted among participants at an international educational conference on inflammatory bowel diseases. Participants classified 20 theoretical cases...

A 62-year-old woman with porto-sinusoidal vascular disorder and portal hypertension was admitted to the emergency department for hematemesis anemia (hemoglobin 8.1 mg/dL). Five years ago, she had been treated at another hospital two sessions of endoscopic variceal ligation (EVL) esophageal bleeding. After hemodynamic stabilization, an upper gastrointestinal endoscopy performed large-caliber varices red signs were found in middle lower third esophagus. There no active EVL (Speedband Superview...

Abstract Background Some epidemiological studies suggest that long-term exposure to environmental air pollutants, such as particulate matter (PM), could have a role in inflammatory bowel disease (IBD) incidence and pathogenesis. However, less is known about the potential effect of short-term pollution exposure. The aim this study investigate whether associated with occurrence IBD flares. Methods Anonymized hospital discharge records (HDR) ICD-9-CM codes 555 (Crohn’s disease) 556 (ulcerative...

Abstract Background Subcutaneous (SC) infliximab (IFX) effectively maintains biochemical, clinical and endoscopic remission in inflammatory bowel disease (IBD) with a comparable safety profile to intravenous (IV) formulation. Transmural healing is considered desirable long-term treatment endpoint IBD, especially Crohn’s (CD). Whether switching from SC-IFX transmural IBD still unknown. Methods This preliminary report prospective multicentre cohort study on patients IV-IFX switched SC-IFX....
