Study objectives	An important problem after surgical resection of Crohn's disease remains the high risk of recurrence. The anastomosis region is the most common localisation for recurrence and may lead to prompt reoperation. The configuration of the anastomosis is an often discussed reason for this phenomena. Wide stapled latero-lateral anastomoses appear to provide fewer relapses due to a reduced risk of re-stenosis than conventional sutured end-to-end-anastomosis, on the other hand there seems to be an increased risk of fistulas after stapled anastomosis. The existing literature on this topic has several essential deficits thus reducing their validity. Therefore a randomised controlled multicentre trial under standardised conditions is necessary to achieve a high validity to investigate the influence of latero-lateral versus end-to-end ileo-ascendostomy on recurrence and complications after ileocaecal resection in patients with Crohn's disease.
Ethics approval(s)	Local Medical Ethics Committee gave approval on the 20th October 2005
Health condition(s) or problem(s) studied	Crohn's disease
Intervention	Group one: ileocaecal resection with conventional sutured end-to-end ileo-ascendostomy Group two: ileocaecal resection with stapled latero-lateral ileo-ascendostomy The total duration of follow-up for both treatment arms is 3 years.
Intervention type	Other
Primary outcome measure(s)	Endoscopic proven perianastomotic relapse of bowel inflammation one year after surgical resection (using an endoscopic relapse score).
Key secondary outcome measure(s)	1. Endoscopic proven perianastomotic relapse of bowel inflammation three years after surgical resection (using an endoscopic relapse score): one and three years after randomisation 2. Symptomatic perianastomotic relapse (diarrhoea, pain, fever, weight reduction, increasing inflammation parameters in blood): one and three years after randomisation 3. Relapse with indication for surgical resection: one and three years after randomisation 4. Anastomotic leaks: day of discharge from the hospital
