Synonym(s): Ovariosalpingectomy, Salpingectomy, Salpingotomy, Spay, Neutering


Introduction

  • This is a fast and easy procedure in young animals used for prevention of unwanted pregnancy and development of ovarian and uterine disease.
  • It is also used in middle aged to older animals for treatment of ovarian disease such as cystic ovaries. This is the only curative treatment of choice for this condition.
  • Can be performed via the midline or bilateral flank approach.

Uses

Advantages

  • When performed in young animals, it is a fast and easy procedure.
  • Permanent contraceptive solution.
  • More cost effective than hormonal implants.
  • Allows for direct evaluation of the uterine tract and inspection for any early changes: can progress to an ovariohysterectomy in the same surgery if needed.
Midline ovariectomy
  • Easier visualization of organs.
  • Requires less experience.
Flank ovariectomy
  • Less exposure and involvement of the gastrointestinal tract compared to the midline technique:
    • This reduces risk of post-operative adhesions.
    • Less heat loss during procedure.
  • Although requiring two separate incisions, they are located dorsally out of the reach of the animal and not in direct contact with any bedding used post-operatively:
    • Lower risk of post-operative infections.
  • Post-operative healing is faster:
    • The incisions are smaller and not subjected to the weight of the abdominal organs vs midline incision.
  • Faster post-operative recovery.

Disadvantages

  • For treatment of ovarian disease, it is more invasive than medical treatment.
  • Requires a general anesthetic.
  • Risk of post-operative complications.
Midline ovariectomy
  • Operating time is usually longer due to involvement of the gastrointestinal tract.
  • Increased heat loss.
  • Slower post-operative recovery.
  • Potential higher risk of post-operative adhesions.
  • Poorer wound healing.
  • Higher rate of post-operative infections.
Flank ovariectomy
  • Does require some surgical experience.
  • Two separate incisions needed.
  • Requires manipulation of patient mid-surgery.
