Plain-English summary

A 10-year-old Limousine cow and an 18-year-old Thoroughbred mare were both having trouble breeding due to large growths in their uteruses. After examining them, veterinarians found these growths were uterine leiomyomas (a type of tumor) attached to the uterine wall. They successfully removed the tumors using a minimally invasive endoscopic technique, which helped preserve as much healthy tissue as possible. Both animals recovered quickly and returned to normal breeding function after the surgery.

Abstract

OBJECTIVE: To report successful minimally invasive treatment of a uterine leiomyoma in a cow and a mare. STUDY DESIGN: Clinical report. ANIMAL POPULATION: Limousine cow (n = 1), Thoroughbred mare (n = 1). METHODS: A 10-year-old cow and an 18-year-old mare were presented for difficulties in breeding and infertility, respectively. Examination of the reproductive tract revealed the presence of a large mass attached to the uterine wall via a wide and short peduncle in both cases. The mass expanded into the uterine lumen in the mare and into the abdomen in the cow. Both masses were removed using a minimally invasive endoscopic approach and a vessel-sealing and dividing device. RESULTS: Minimally invasive surgical resection of a subserosal and a submucosal leiomyoma with maximal sparing of uterine tissue resulted in a short convalescence period and apparent return to breeding function in a cow and a mare. Use of a vessel-sealing and dividing device provided excellent hemostasis and decreased tissue handling. CONCLUSION: Leiomyoma with short, wide, and thick peduncles were treated successfully in a cow and a mare with minimally invasive endoscopic approaches aiming at maximal uterine tissue preservation.
