I had the gastric emptying. I stayed for 4 hours and mine turned out totally normal. I think at the 4 hour mark I only had just traces left in my stomach.
I believe that if you have delayed stomach emptying, it can cause you to have wrap issues because things are not moving through fast enough and it puts pressure on your wrap. I am not an expert on this, but your results are really good so that just means that its another indicator you are a good candidate for surgery.
