I had the PPH operation one year ago, since then I have been feelingpainful dully and comfortless on the healed cut. The twice CT show that more than 20 titanium nails form a circle. The cut anastomoses well and smoothly. All the nails have been covered under the mucous membrane and can’t be found by touching. I want to know whether there is any method to get the titanium nails out and whether there is any danger to do so.
