Also, not to give you yet another option, but some people opt for temporary diversion, with the intention of hooking the pouch back up later on. There is a school of thought that "resting" the pouch for a time will give it a chance to heal, allowing for a reconnect later on.
However, in that case, you would most likely be stuck with a loop ileo rather than an end, and a loop is really not ideal for the long term.
