Study start date: July 1, 2004

Actual date on which the first participant was enrolled.

Our ongoing natural history studies of the etiology and immune abnormalities of the group of diseases known collectively as the inflammatory bowel diseases require access to clinical samples of intestinal tissue as well as blood samples for genotyping. This protocol provides a mechanism for procurement of intestinal samples obtained at the time of medically-indicated surgical procedures from patients with IBD or some other non-IBD diagnosis (to act as a control group). In addition it allows for the procurement of blood for DNA preparation as more IBD susceptibility genes are discovered and we further our work on association of genetic polymorphisms/mutations with the phenotype and immune abnormalities observed in our IBD patients.
