It's pretty easily visualized in the 12 weeker. When you see the ovary, which has the cauliflowery look you will see a white strip down below it at the back running toward the tail, which is the oviduct. The thing you have to watch out for is the blood vessels that run with it, so a pair of very small forceps to pick it up without getting hold of the blood vessels is a definite plus. Those recessed ear forceps are awesome for that because your hand doesn't get into your line of sight. I lift it up with the forceps, make a little hole in the connective tissue behind it, the grasp and lock it with a pair of hemostats. I let the forcept hang free outside the cavity, so the oviduct is elevated. Then you have two hands to finish loosening it up and dissecting it back as far s you can toward the ovary. once the upper end is loose, then use the hemostat to lift up and out of the abdominal cavity and cut it as far down as you can without damaging the intestines. And you're done.
