"Gerbovich wrote in his diary that night:
“When Rogozov had made the incision and was manipulating his own innards as he removed the appendix, his intestine gurgled, which was highly unpleasant for us; it made one want to turn away, flee, not look—but I kept my head and stayed. Artemev and Teplinsky also held their places, although it later turned out they had both gone quite dizzy and were close to fainting … Rogozov himself was calm and focused on his work, but sweat was running down his face and he frequently asked Teplinsky to wipe his forehead … The operation ended at 4 am local time. By the end, Rogozov was very pale and obviously tired, but he finished everything off."

Auto-appendectomy in the Antarctic: case report — Rogozov and Bermel 339: b4965 — BMJ - A Russian physician stationed in the Antarctic operated on himself to remove his own infected appendix. Amazing.
