The fistula, the fistula

Again, we are having trouble with the fistula.  As we are feeding Peter more formula, the fistula output is getting cloudy, like a watery milk color, and is going up in volume.  We gave him blue food dye in his formula today to see if it is formula coming out of his fistula.  The good news is that no blue food dye came out the fistula; we saw it all exit the ileostomy.  The bad news is that there is likely something going on that needs to be addressed.    We will be collecting some of the fistula output for analysis.  Details about what the problem is and how to manage it are still to follow.  I don't think the docs feel it is something terrible, but it does seem to be a setback in our goal of getting him off IV nutrition.
