Endoscopic-assisted resection of a pedunculated uterine leiomyoma with maximal tissue preservation in a cow and a mare.

This research reports on the successful application of a minimally invasive surgical technique to remove uterine tumours (leiomyomas) in a cow and a mare, using an endoscope and a vessel-sealing and dividing device to safeguard maximum uterine tissue.

Objective and Research Subjects

• The study sought to look into new methods of surgically removing uterine leiomyomas – a type of noncancerous tumor in cows and mares, with a particular focus on minimizing damage to the existing uterine tissue.
• This process was done on a 10-year-old Limousine cow and an 18-year-old Thoroughbred mare. Both of these subjects had trouble breeding – infertility in the case of the mare, and unspecified breeding difficulties in case of the cow.

Methodology

• Initial examination of the reproductive tract of both animals revealed a large mass attached to the uterine wall by a wide and short peduncle (stalk).
• In the mare, the tumor extended into the uterine lumen (cavity), and in the cow, it extended into the abdomen.
• To remove these tumors, the researchers used a minimally invasive endoscopic approach, combined with a vessel-sealing and dividing device.

Results

• The surgical procedure was successful and resulted in maximum sparing of uterine tissue in both animals.
• In addition to this, there was a short convalescence (recovery) period, and both animals seemed to return to functioning breeding.
• The vessel-sealing and dividing device proved to be extremely useful in providing excellent hemostasis (stopping bleeding) and minimizing tissue handling.

Conclusion

• The study concludes by asserting that the minimally invasive endoscopic procedure aiming at maximal uterine tissue preservation was successful in treating leiomyomas (with short, wide, and thick peduncles) in a cow and a mare.
• This breakthrough could potentially change the way these conditions are treated in the future, providing a less invasive and more sustainable method for preserving the breeding capability of livestock.
