Omg NO I wasn't offended at all. It IS funny in a very pathetic way. My husband now wants to go visit the place as a part of a museum mile tour. No thanks.
Yeah Diatriozic Acid is the contrast solution better known as Amidotrizoic Acid or Gastrographin...so I get it now...this basically makes them come out in final and in tact (takes me a while sorry)..... Here is an older abstract by NCBI on "ejecting cestodes":

I see what you mean....it looks like the bomb and if I knew I had a Tapeworm (i'm not sure what mine is) I surely would want to make SURE the thing was out and it looks like this is the way. It's controversial (here) so you would have to go elsewhere to get it I am sure or you would have to find someone here who uses it for adhesive bowel obstruction....that would be hard. I'm assuming you know or highly suspect you have a tapeworm.
I would contact this doctor and get some leads and/or contact NCBI at NIH (sponsored the original studies it looks like). It was a long time ago but you never know.
Japan just seems like the place naturally right? The land of raw fish? So this parasitic infection is not looked at as such an "anomaly" there due to the amount of raw fish eaten. And, in fact, it looks like this is the "usual" method they use. Pretty advanced place. Impressive.
And here there on the site it says....
"Since Oi et al.  reported the successful expulsion of unfragmented cestodes by intraduodenal injection of amidotrizoic acid (Gastrografin; Nihon Shering), many patients in Japan with cestodiasis have been treated with this agent . Gastrografin injection is now the treatment of choice for cestodiasis in Japan"
I am going to Thailand in a few months and if I, before then, I find out that THAT is what I have and the people who would accurately diagnose and treat it were in Japan, I absolutely would go there and get this stuff. Absolutely. I would email good ole Dr. Gatanaga and get them to hook me up! They may even do it in Bangkok as well IDK. I would not have even thought about that because the places that I have been in mainly were really really behind.
I'll bet though that one could even find a clinic there that was above ground AND had ventilation too :)
