Crohnes Major Surgery?

My specialist is referring me to a doctor in a bigger city to do a surgery for my crohnes disease. They are going to scrap out inflamed tissue in my bowel because theres too much irritation for medication to treat effectively. Can you tell me about the name of the surgery and it's recovery time and the pain level of recovery? Because i've read some sites that say surgery for crohnes consists of removing part of the bowel, that sounds like cutting me open and chopping off a limb to me, and the nurse describe it as just scraping tissue... I'm going to ask when they call back but I want a more immediate answer?
