Brian, I had ileostomy surgery in June and had a wound vac on from the end of June thru mid August. I had a lot of infection inside my abdomen, so they cut it and the scar tissue out and didn't staple anything, so my abdomen had large wounds to heal. The wound vaccuum hurt me so bad at first that I would always cry, especially when it was turned on. I had a home health care nurse come in twice weekly and we would repeat the procedure. Towards the end, it didn't hurt anymore, but I don't ever want one again! Also, it can't be hidden and it makes noise, especially if there is a leakage.
