Reminds me of the story about Hugh Glass. At one point a bear disemboweled him. He apparently either killed or at least severely discouraged the bear using a hunting knife, pulled his guts back into his abdomen, made a poultice using moss and herbs, and eventually made his way back to town with a story and some pelts.

If this sounds suspiciously like The Revenant, it's because that movie was based on the story of Hugh Glass. Beyond surviving a bear attack the stories surrounding him are fanciful at best
