A bit of reading suggests that colonic irrigation and enemas are the same thing - cleaning of the lower intestine by introducing water which causes the bowels to excrete their contents.
I don't see that this can be bad for you given that there are people that need to do this every day in order to get rid of their faeces - ie. anyone who has had an operation that means they no longer have the last part of their intestines (their rectum), and instead have to apply an enema via a stoma (hole in the abdominal wall direct to the intestines)...
As to whether it is better for you than getting rid of your poo the regular way i don't know?...
