Er, self surgery isnt recommended. A little story:
I had heard on a captain in the Army who thought he was tough as nails. Well, he cut his arm open one fine day, and, thinking himself Rambo, decided to stitch himself up. He got to stitch #2, and passed out.
I have read that, in a wilderness environment, because it is almost impossible to keep an area sterile, if the surgery diesnt kill the patient, sepsis, or other massive infections, most likely will.
