It sounds like you've gone through a lot. IBD or inflammatory bowel disease includes
both ulcerative colitis and Crohn's. The
main difference between the two are location and the degree that the intestine
is inflamed. Crohn's can affect anywhere
through the entire gastrointestinal tract, from the esophagus through the
rectum, while ulcerative colitis in confined to the colon. Colectomy usually cures UC, so if symptoms
are recurring Crohn's may be the diagnosis.
This should be easily known by having you doctor look over the pathology
report from the surgery to know how much of the intestine was inflamed.
