Here is a short video of myself and, a friend performing surgery on a 4 day old hatchling Black Headed Python to remove harden yolk (sometimes called hard belly) from the intestinal tract.
If the harden yolk is not removed....it is certain death for the hatchling as it can't digest any food because of the blockage.
It's not for the weak stomached.....it's a bit gross. haha. And... the harden yolk has the look, texture and feel of spam.....yuk. lol.
We simply go in through the umbilicus and move the harden yolk to on end of the opening and push out. Sometimes (as in this case) we have to dig around in there a little bit to actually find the harden yolk.
Thus far, I've only had to do this a few times and, in each case....the animals thrived.
