J.W.
I have one word of advice. INFORMATION. I am a nurse but that doesn't make me an expert on every medical condition although my family sometimes thinks so. I would do some internet searches and find out a couple things:
1. what exactly it is including worst and best case senerios.
2. how it is diagnosed..palpition(the MD feeling it),x-ray, MRI, CTscan, upper & lower GI series..and how it is treated medically vs surgically
3. revisit the surgeon and ask all the questions that you learned from your research
4. ask what are the outcomes of treatment short term vs long term...immediate cure or lasting disability...how it will effect her digestive tract and reproductive system
Don't be afraid of what you will find out. Your child all ready has the condition. She was born that way and that fact is completely out of your control. Your power is in knowing your battle and the weapons you'll use to beat it.
You are a good Mom you'll decide what's best for your child. And doctors do this for a living they know what they're doing. Millions of people are treated everyday by talented doctors that you never hear on the news...The rare quack is the only thing you hear on the news because it is rare that doctors don't know what they're talking about. You will get though this because there isn't anything else to do but go though it. We will say a pray for you that you pass though it with calm and stregnth.
