Julie,
There are a few things I am unclear about in regard to your husband’s proposed treatment. First, the notion of “detox” in reference to gut cleansing is generally thought of as pseudoscience at best, and this is when you have a colon. Without a colon, what would you be “detoxing” anyway? And, bring your own enema kit? What sort of treatment center is this? My primary concern is that your husband might be getting involved in treatment that is without evidence based data and/or ineffective. There are many of us who have struggled with chronic pouchitis, and we have tried many non-medical options. Usually, they waste our time and money. But, if your husband has success with this, please come back and let us know.
I have heard of tap water enema rinses (typically before bed), but not for detox. This is just to facilitate complete pouch emptying. Some people find that it helps prevent bacterial overgrowth inthe pouch. As stated before, just use an empty Fleet enema container.
Most people hope to restore normal gut flora using oral probiotics. Failing that, fecal transplant has been used with varying success. But that is so far only approved to treat persistent C. difficile infection.
