Years ago, I had a boxer with this condition. He was in a lot of pain with it and the surgery had to be performed very quickly. They had to remove about 12 inches of his small intestine. They didn't ever find what caused it (they called it the "telescoping" of his intestine). I am so glad you still have your baby after taking such a long time to diagnose the condition. It must not have been a complete blockage.

I had the same thing about 10 years ago. It took about 18 hours of tests and no pain meds in the ER before they did surgery, and they still had not figured out what it was before they cut me open! In my case, some scar tissue (what?!) in my intestine had caused it to kink up and cause a blockage. It was the most painful thing I've ever had!! I've had 3 kids and this was WAY worse!

Thank goodness he had the surgery and is doing better!
