Do not try this at home! As far as stories of “guts” goes, this one wins the golden appendix award. During an expedition to the Antarctic, Russian surgeon Leonid Rogozov came down with serious appendicitis. As the only surgeon he was faced with death or performing the operation himself! There was no chance of flying out because of the snow and blizzards. So, Rogozov did an auto-appendectomy. He instructed people to help, but had the obvious problem of not being able to use a general anaesthetic, since he had to remain conscious and functional, obviously. So, he just injected novocaine, and got into professional detached operating mode. And, despite everything, he successfully completed the operation, and returned to normal duties in just two weeks. Talk about manly toughness!

It has been said that where there is no surgeon, no medical help whatsoever, it is better than nothing to Face the inevitable bursting of the appendix by sitting upright with the knees pulled into the chest, so if lucky, pus might drain into the bottom of the pelvis, and become walled off into an abscess. I don’t know if this would work, but in such a situation, one might try anything. Articles also report that antibiotics taken soon enough might help:
