Animals can live a surprising amount of time with a permanent hole to their stomach, especially if it is a surgically made fistula. Humans have had fistulas; the first human on record as having one was a French Canadian by the name of Alexis St. Martin. He sustained a life-threatening musket wound in 1822, and was marked a terminal case by his physician. However, he managed to heal and was mostly functional again within two years – except for a hole in his stomach that would never close. Through this hole doctors were able to examine inner workings of his stomach.
