How is a Keyhole Spay performed?
A step-by-step photo and video guide
1. Once asleep under anaesthetic, she is placed on her back onto the special tilting keyhole table and safely secured.
2. The abdomen is clipped and prepared in a sterile way
3. She is covered with a sterile drape in preparation for surgery
4. The drape is held in place with towel clamps
5. An imprint is made at the site of the planned trochar entry point
6. This is repeated for the second trochar
7. Local anaesthetic is injected into the imprinted areas in which the incisions will be made. This provides 6 hours of post operative pain relief
8. Two small 10 and 5mm incisions are made in the skin
9. An incision is made into the muscle layer to allow insertion of the large trochar
10. The trochar is carefully inserted into the abdominal cavity
11. The camera is white-balanced to ensure correct visualisation of colour. Carbon dioxide is pumped into the abdomen via the yellow tubing. This results in inflation and expansion of the abdominal cavity which enables better visualisation of the ovaries
12. The smaller trochar is positioned to allow placement of the camera
13. The trochars are held in position by a sterile assistant
14. Grasping forceps are used to pick up the ovary and the uterus is examined
15. A triangle is made with the uterus on the left of the picture and ovarian ligament on the right. The ovarian artery can be seen as the spiral in the middle of the triangle.
16. The ovary is positioned against the abdominal wall and finger pressure is made from outside the abdomen by the assistant. This is a guide as to where a hook should be positioned that will hold the ovary in place.
17. The hook is pushed through into the abdomen
18. The ovary is passed through the hook and released from the graspers
19. A special piece of equipment is used to cauterise (burn) the tissue sandwiched between the yellow prongs. The blade is then used to cut along the centre.
20. A close up view of the spiral ovarian artery
21. This photo demonstrates the blade cutting between the cauterised tissues.
22. The ovary is then removed through the hole made by the large trochar
23. The removed tissue is examined to make sure the entire ovary has been removed.
24. The dog is turned to the opposite side and the procedure repeated
25. The internal muscle layer is closed with a dissolvable stitch
26. The skin is closed together with skin glue. This is the final appearance of the surgical wound
27. Ready to go home!
