Honestly, I don't know, but if I had to guess it'd be the 3-footer. I asked the tech before they knocked me out if it would take as long as a colonoscopy and he said that sometimes they're out in 10 minutes with upper endoscopy. That leads me to believe that it is a short one. I know he was specifically looking at a spot he thought was narrowed in my duodenum, which didn't end up being narrowed, but sharply bent. Seems like 3 feet would be sufficient. But to be perfectly honest, I have no clue.
I did have a pillcam about a month ago, so scopes have literally been all through my guts. I know the pill can't biopsy, but at least he's gotten a visual of everything.
I had a positive prometheus IBD serology, which is the reason he went beyond a colonoscopy in the first place. From what I've researched, it seems like most feel that test should not be used in initial diagnostics. Maybe it was a false positive, I dunno. I was a little surprised that he's never done any other blood work, although maybe if you're not clearly "flaring" then that would be as big a shot in the dark. No mention of CT scans or any barium tests. At least I know that Crohn's can hide out and be all sneaky, so I'm aware of this stuff for future reference, you know?
Just for the sake of background I have these really periodic episodes of diarrhea and cramping, and actually haven't had one in all of May. Coincidentally or not, I've been on probiotics for that time. I'm not in chronic pain by any means. I know my GI thought IBS right off the bat, but told me he had to exclude Celiac and Crohns first. I'm not even sure my symptoms fit that textbook IBS definition. I don't know. If I hadn't fainted from one of those episodes, I'd have never gone to the doc in the first place, as we have a high deductible insurance plan.
So I guess barring any weird results from the biopsies, for the time being I am not a Crohnie. While I'm thinking about it...he says I have "esophagitis" which is inflammation of the esophagus...so how do they tell that sort of inflammation apart from the type associated with Crohn's Disease?
Thanks and sorry this got so long!!
