Summary

Ovariectomy (OVE) using electrothermal bipolar vessel sealing (EBVS) is a safer and faster spaying method for pigs compared to traditional ovariohysterectomy (OVH). This technique resulted in fewer complications and quicker recovery times, suggesting OVE can replace OVH.

Area of Science:

  • Veterinary Surgery
  • Animal Reproduction

Background:

  • Traditional ovariohysterectomy (OVH) for spaying pigs involves hand-tied ligatures.
  • Ovariectomy (OVE) using electrothermal bipolar vessel sealing (EBVS) is a newer technique being evaluated for safety and efficacy.

Purpose of the Study:

  • To compare the safety and efficacy of OVE with EBVS versus OVH with ligatures for spaying pigs.
  • To assess intraoperative and postoperative complications, surgical time, and recovery periods for both techniques.

Main Methods:

  • A retrospective case series reviewed medical records of 14 intact female pigs undergoing sterilization.
  • Pigs were divided into two groups: 5 undergoing OVH and 9 undergoing OVE.
  • Data collected included surgical technique, complications, hospitalization length, and long-term outcomes via owner questionnaires.

Basic Surgical Techniques in the Göttingen Minipig: Intubation, Bladder Catheterization, Femoral Vessel Catheterization, and Transcardial Perfusion

Published on: June 26, 2011

Main Results:

  • OVE resulted in significantly shorter mean incisional length (12 cm vs 22 cm) and surgical time (50 min vs 103 min) compared to OVH.
  • Postoperative complications were less frequent in the OVE group, with a significantly shorter return to normal behavior and appetite (1.1 days vs 4.3 days).
  • No significant differences were observed between groups after a mean follow-up of 36 months.

Conclusions:

  • OVE using EBVS is a faster and safer surgical technique for spaying pigs than OVH with ligatures.
  • The EBVS technique offers reduced perioperative complications and faster recovery.
  • OVE with EBVS is a viable alternative to OVH for pig sterilization.
