I saw this story on another site, searched it here and couldn't find it, but thought it would be a good submission to the Cellar.
In early May 1961 a Russian surgeon named Leonid Ivanovich Rogozov was the only medical personal on a mission to the Antarctic to build a new base. On this mission, Rogozov diagnosed himself with acute appendicitis. Being the only surgeon in a remote location gave him little option; he had to preform the surgery himself or die.
I can't even imagine having steady hands while operating on myself.
