This is an absolute contraindication to tummy tuck in my opinion and a sure case in which infection and risk outweighs any possible benefit
Thanks for your question. Unfortunately there is no simple answer as it depends on many factors including the extent of the tummy tuck required, the placement of your ileostomy. Generally speaking abdominoplasty surgery would not be recommended if you have an ileostomy but discussion with and between your general surgeon and a fully qualified plastic surgeon would clarify this for you.
