Never heard of staples staying in more than 10/14 days.
APR surgery 2/20/06, discharged from hospital 2/24, appointment with surgeon and Staples Out on 3/2 ... 10 days.
Almost 5 months post op now and still have visable pink spots either side of my incision where staples were. You might try the ointments for scars, but they didn't seem to make much difference on mine.
