I Had Surgery They Left Staples On The Inside. Is This Normal?

Normally not,but due to the new technology is possible if the staples are made of some harmless material that disintegrate with time inside the body
or can be possible they are stitches??
With material made out of animal organs
as cat tripe that same way it just disintegrate inside the body

Yes it is normal to leave staples on the inside after surgery.

Most staples now days are dissolved while your skin heals; otherwise your doctor would have to remove the staples in a followup visit.

When in doubt, call your doctor's office.

Best wishes!

It is a common practice to leave staples on the inside incision to strengthen the cut so as not to cause tearing of the tissue and a general weakening of the area that was cut.
