Thanks for the link. I'm excited that Crohns seems to be an area with promising active research so we might have it solved in the next few decades. For me personally, as my condition is only mild / moderate, I believe I should be able to get it under control without the more experimental methods, although will always consider them when appropriate. Between my father (who is a doctor) and my mother (who is ... open minded), no potential treatment seems to go unanalysed in my household.
