First off, it probably is not a good idea to use those terms, because they basically just indicate whether you intend to keep the ileostomy or not.
But, often, an end ileostomy is referred to by lay people as a permanent ileostomy. But, it can be temporary (as in the first step of a 3-step procedure). This is where the end of the small intestine is brought out through the abdomen. The rest of the small intestine/pouch is sewn off "blind" inside or removed. This type of ileostomy is easiest to care for, because it leaks less and you can keep a better seal with your wafer.
Usually what is referred to as a temporary ileostomy is actually a diverting ileostomy or loop ileostomy. This is where both the upstream and downstream sides of the small intestine is brought out through the abdomen, like a double barrel shotgun. Sometimes, people keep this type permanently. This type of ileostomy tends to leak more because it can retract or the shape can be odd. So, for long term or permanent status, it is not the preferred type.
If it is your intention to not put your pouch back into action after a respite with ileostomy, you want an end ileostomy, not a diverting ileostomy. But, the diverting is easier for the surgeon to perform and reverse.
Surgeons generally ALWAYS assume you will change your mind and want to reverse it. Another thing to think about is that they may be able to use your pouch to create a continent ileostomy, so you do not want to just trash it. A loop ileostomy will maintain a little bit of fecal stream, perhaps enough to maintain the health of the mucosa. Complete diversion could lead to diversion pouchitis, and make using the pouch for the continent ileostomy a little more tricky.
