Abstract: | Objective: To review the efficacy and safety of unilateral ovariectomy by use of a standing hand‐assisted laparoscopic approach and evaluate the effect of ovary size on posttransection hemorrhage after application of a linear stapling device. Study Design: Case series. Animals: Horses (n=65) aged 2–20 years. Methods: Medical records of mares that had ovariectomy performed by use of a standing hand‐assisted laparoscopic approach were reviewed. Data retrieved were signalment, ovary removed (left, right), ovarian size, ovarian pathology, intraoperative and postoperative complications, and length of hospitalization. Results: Mean ovarian diameter was 17 cm. Histopathology (52 mares) confirmed 41 granulosa cell tumors (79%), 8 ovarian cysts (15%), 1 teratoma (2%), and 2 ovaries (4%) without abnormalities. Hemorrhage was observed laparoscopically in 16 mares after transection of the mesovarium. Complications encountered during surgery included 1 mare collapsing in the stocks and 1 mare that hemorrhaged excessively from the incision. Postoperative complications included 2 cases of mild colic. Overall complication rate was 6%. Conclusions: All attempts to remove the target ovary were successful. The approach is safe for the mare, as complications encountered were similar to those recently reported for other approaches. |
