Basically, you don't want ANYTHING in your body to be necrotic (probably not spelling it right, but it's phonetic).
Pete had his gallbladder removed this morning/afternoon and it was necrotic. The surgery went very well, and if you're easily grossed out you probably don't want to read this part, but the good news is that though it was enlarged and pretty yucky looking, when they cut it in half, the pus was all inside. That's where you want it, not floating around your stomach cavity looking for something to make sick. Because it was so well contained, the incision was very small and he should recover very quickly. I am probably being overly optimistic thinking he might be back at TIRR by the weekend, but I can do that every now and again.
He is on his way back to his room now, although I expected he would already be here. I will give him a big kiss for everyone. Thank you all very much for your prayers and kind thoughts.
