i had mine out almost 3 years ago.
no ill effects if anything i am able to eat better, no more heart burn like pains in my upper right abdomen.

ok when i eat excessive amounts of red wine and fatty food i get teh runs, but i can still eat it in moderation.

have enevr had pain in the area since teh operation
it is done through key hole surgery so 2 or 3 2 cm cuts
