Thanks for getting in touch. Yes, I feel very lucky.
You should check with your Doctor or a Nurse in your Care Team. I think it does depend on the kind of operation(s) you had and therefore what kind of stoma you have.
I then lived in England and had cancer in the lower bowel and after chemo and radiotheray I was successfully operated on. After a few months they told me I could try irrigation so I ordered the supplies and bought an irrigation pump from Braun (about#300).
Since 2005 I have been successfully irrigating and actuallu use stoma plugs (yes, no bag!). Unforyunately, I could not sourec the stoma plugs in the USA or Canada so I have them shipped once a year from the UK wher my family order them before shipping to me. The plugs are great because in conjunction with the irrigation it (usually) means no movement at all for two days and I pretty much operate as I used to.
Hope this helps.
