Hi there... let me offer up my input on the surgeries....
They did a colonoscopy in November, and couldn't get the scope through the stricture in my ileum area (no ileum there though, because they took that out in 2007). I had surgery in January (actually 2 weeks ago yesterday), as I was having partial obstructions in December, more frequently than usual.
This was my second surgery. First surgery, they removed 20 cm of my small intestine, the ileum area (so that included just a small bit of the large as well). The second surgery... which was 6 years later... removed about 40 cm... with 30 being in the ole ileum area once again.
Even with both surgeries, I don't have a ileostomy. I have to take some medicine to help with the short bowel issues... but otherwise things are going fine. I am back at work already, started Monday as I felt like I could do it. So far it has been no problem... and I have been working full 8 hour days. Though keep in mind that my job is a rather sedentary job... I sit in front of a computer all day and don't do a huge amount of moving.
I think this surgery will vary depending on the surgeon and what they do. I call my surgeon a bit of an artist. She has done wonders with many people in the past. My last surgery, they did two port holes and a small 2 inch incision along the bottom of my belly. This time around, they didn't even do any port holes... just the two inch incision. I couldn't believe they could do what they did with just that one hole.
Anyway, just stay positive. Depending on how much they remove, you may not need an ostomy. For both of my surgeries, I haven't needed it... so I guess it all varies depending on surgeon and person...
Stay positive, and hope things get better for you soon!
