Hi Disney mom--mine started after exactly 19 years too-must be a jinxed number! I hope you only have one episode and they go away which can happen--these are awful to live with. I'm still kind of bitter and trying to process mentally having to live in chronic intestinal pain--I thought that once my colitis was cured by this surgery way back when, those days would be done Anyway, my surgeon said it isn't unheard of for blockages to start decades after surgery--something about adhesions getting stronger over time and/or our bodies slightly shifting with age. She also said many adhesion problems don't show up--even on CT's. It's frustrating because I don't think this is something regular, unspecialized doctors know (i.e. ER doctors). Every ER dr. I've seen says "oh you're fine" (despite being doubled over in pain and puking) and 1 hour later the surgeons come in and say "no, she has a blockage". It gets old having to keep proving this to ER physicians. Please keep us updated on how things go, and good luck.
