I'm happy for you! As long as there is no severe underlaying condition, rabbits often recover from ileus if the problem is detected and treated quickly. Now, it would be better to understand why the problem occured to avoid a repeat. It might stem from a bit of stress (Aki had a brief episode last december after a tree was cut just in front of the rabbits' room, she was moulting at the time and well stress + lots of hair was enough to provoke stasis), a hay your rabbit doesn't like much, something he ate (like fibers from a carpet...), but it might also come from a health problem.
