Colpotomy: Stab Incision.

Colpotomy: Stab Incision.
One gloved finger is inserted through the stab incision in the fornix, and it enters the peritoneal cavity of this cadaver specimen. Notice the flaccid horns of the uterus. For a live mare she is sedated and given epidural anesthesia. It is imparative to induce pneumovagina to stretch the vaginal wall. A 2 to 3 cm incision is made in the fornix at a 10:00 or 2:00 o'clock position [depending on whether one uses the left or right hand respectively].
