I've had two resections and it took some time after both to get a more predicatable bowel schedule! At first, I was constantly having "run-as-fast you can diarrhea"! Talk with your dr., though. He/she can give you tips on things to do . . . I took lomotil/immodium for awhile and that helped. I was also told to start fiber when I was able since I wasn't in danger of a stricture anymore . . .
I had pretty much the same resection done in July 07. It takes several months for things to slow back down. I am 6 months out and am FINALLY getting to where I can eat out or at family gatherings and not stress out about it. As always with Crohn's you never know so I am still aware of bathrooms and whatnot, but its much better. When I came home from the surgery and started eating it was about a 15-30 min period where I would stay close to the bathroom (and that would last for awhile till I was sure I wasn't going to go anymore) and now at this point, sometimes I might not go for 4-6 hours after eating. It will get better. :)
I had an ileal resection, with removal of the appendix and ileocaecal valve, in October, 1999--and, with rare exceptions, I've had the diarrhea and urgency ever since. Any medications that I've been given either (a) are opiates and keep me from driving when I take them, or (b) block me up miserably (e.g., cholestyramine), with uncomfortable gas bubbles and much worse diarrhea when the drug wears off. No doctor has been able to find a way to alleviate these symptoms.
Other people (as above) seem to have had better luck than I have with remedies after an ileal resection. What the heck--I'm used to the whole syndrome now.
