My Little Penguin, I have no idea! This was his 3rd or 4th endoscopy/sigmoidoscopy. She stimulated his pancreas this time and took samples from that. Before, his GI thought he has cystic fibrosis and did sweat tests, and the first came out borderline positive, which about gave us heart attacks. The second came out normal. His blood work has always been off, but not crazy off. I assumed she was looking for more scarring in his esophagus or strictures - his past tests have shown scarring consistent with bad reflux. The nurse called and told me his esophagus looked good, noe strictures, no more scarring, but the Dr. wanted to see me that day. His twin Abby hadn't been discharged from FL Hospital yet, so I couldn't get him across town to Arnold Palmer Hospital on Fri. I don't know everything they did biopsies for, but when I google active focal colitis, which the nurse said they found, it says the causes can be colitis caused by infection (possible I guess, but its not as if he's more sick than he always is) ischemia (lack of blood flow usually found in old people) or Crohn's and that it especially correlates to Crohns in children. The nurse said I have to come in to discuss "his treatment options and plan" so I know there is something more involved going on. I've learned the only time I don't get details even when I'm pushy is when a Dr. has bad news and wants to give it in person! I'm going to assume he needs more tests though, since the GI hasn't done blood work in two years. Should I ask for testing for EOS? ( not sure what that is... Going to google it now!). Tha is everyone!
