Very interesting, thanks for posting that! That's not entirely unlike what I've been experiencing, though I believe my obstructions might originate slightly above the pouch, given my history of adhesions and the area where the abdominal discomfort tends to be localized (near the old stoma site). But then again, the cramping and abdominal discomfort could also be caused by stool backing up that can't fully enter the pouch. Clearly some stool is passing around the obstruction in both our cases, though, and in my case it seems there's a sudden release and then whoosh and it's all out. So when they pass, they tend to pass fairly quickly, though I'm left with residual discomfort for a day or two.
I've been scoped several times in the last few years, most recently February. Is that how ELS or PRA is diagnosed, I wonder. All things to run by my surgeon, for sure! Thanks everyone for the feedback!
