I did the Agile Patency Capsule bit and 26 hours later the little darling was still in my intestine so no PCE for me. *sigh*
It depends on how "prissy" and diligent you are whether you find the remnants of the APC. There is a tiny "rod" in it. MAYBE 1/4 inch long and 1/6 inch round or wide.
I swalloed the APC on a Tuesday, it was stuck about
the proximal end of the terminal ileum 26 hours later on Wednesday.
Friday I passed the little rod that was all that was left of the APC. I can't swear on the Bible that that little rod would appear on xray but I'm sure that is what its purpose is. The APC itself showed up VERY CLEAR and stark white on xray. At least the entire middle section did, the two rounded ends of the capsule had already started dissolving 26 hours after ingesting the APC.
More than likely that little "rod" is why you aren't a candidate for even the APC, Gachrons. It is small enough to slip into one of those diverticula whereas the APC or the PCE are not. I'm sure the concern is that if the APC didn't pass w/in 26 hours and dissolved in the intestine the "rod" would then be a potential risk for those diverticula as it continued the journey thru.
