HI, hope things are going better for you. I knew there was something wrong with my band when I went from good restriction, to no restriction. While we were doing a fill under floroscopy, you could immediately see that there was a white looking substance that was directly around the port, but it didn't last long. The reason why you can't see it very well is because your body obsorbs it quickly, so the dr. has to be pretty quick, and i had to be laying in a particular way for it to be seen. We saw it once, and then went to do it again, and we didn't see it. He tried to take the saline out to do it one more time, but nothing came out, because the tubing had come apart. So we tried one more time with new saline and i had to remind him how I was position when we saw it leaking. And boom, there it was again. I was lying on my side when it was mot visible. Good luck, and pay attention to how you're laying, watch the monitor so that you can see it also, It is very hard to spot.
