T2-weighted MR can depict Crohn disease lesions and help assess mural and transmural inflammation with the same accuracy as gadolinium-enhanced T1-weighted MR. Combination of gadolinium-enhanced T1- and T2-weighted sequences is useful in the assessment of Crohn disease.

SUMMARY BackgroundSevere ulcerative colitis is a life-threatening disorder, despite i.v. glucocorticoids treatment. Infliximab has been proposed as a safe rescue therapy.

Preliminary studies suggest that similar rates for induction of remission can be expected from 5-ASA enemas and MMx for patients with left-sided ulcerative colitis.

Cyclic administration of rifaximin is effective in obtaining symptom relief in uncomplicated diverticular disease of the colon. The incidence of episodes of diverticulitis in the group treated with rifaximin was lower than that in the group treated with glucomannan alone.

Summary Background  Surgical resection is almost inevitable in Crohn’s disease. Surgery is usually performed for refractory or complicated disease: no studies appear to have been carried out, so far, to evaluate the potential benefits of performing surgery early in the course of the disease. Aim  To compare the long‐term course of Crohn’s disease following ileo‐caecal resection performed at the time of diagnosis (early surgery) or during the course of the disease (late surgery). Patients and methods  Overall 207 patients with ileo‐caecal Crohn’s disease at their first resection were reviewed: 83 patients underwent surgery at the time of diagnosis (early surgery), while 124 underwent surgery 54.2 months (range 1–438) after diagnosis (late surgery). The mean follow‐up after surgery was 147 months (range 12–534). The primary endpoint was clinical recurrence, defined as need for corticosteroids for symptomatic disease in the presence of endoscopic and/or radiologic recurrence. Secondary endpoints were need for immunosuppressants and surgical recurrence. Statistical analysis: Kaplan–Meier survival method and Cox proportional hazards regression model. Results  Within 10 years after surgery, the cumulative probability of clinical recurrence was significantly lower in the early surgery group (Log Rank test P = 0.01). A trend was observed regarding the need for immunosuppressants (P = 0.05). No difference was observed regarding surgical recurrence. At multivariate analysis, early surgery was the only independent variable associated with a reduced risk of clinical recurrence (Hazard ratio, HR = 0.57; 95% CI 0.35 to 0.92, P = 0.02), but not with need for immunosuppressants and surgical recurrence (HR = 0.51; 95% CI 0.20 to 1.30, P = 0.15; HR = 0.66; 95% CI 0.33 to 1.35, P = 0.25, respectively). Conclusion  Early surgery prolongs clinical remission compared to surgery performed during the course of the disease, but the natural history of disease is not modified.
