Laparoscopic ovariectomy using the endo-GIA stapling device and endo-catch pouches and evaluation of analgesic efficacy of epidural morphine sulfate in 10 mares.
Abstract: To evaluate use of ENDO-GIA staples and ENDO-Catch pouches for ovariectomy in mares and to evaluate the efficacy of epidural morphine analgesia. Methods: Randomized clinical trial. Methods: Mares (n = 10) with normal ovaries. Methods: An Endo-GIA II stapler (United States Surgical Corp., Norwalk, CT) was used to amputate the ovaries bilaterally, in standing mares, and Endo-Catch II pouches (United States Surgical Corp.) were used for retrieval. Epidural morphine was used in 5 mares, and procedure duration, volume of lidocaine required to desensitize the ovarian pedicle, and sedation were compared with horses not administered epidural morphine. Results: Use of the Endo-GIA II stapling device was an easy and an efficient method of ovariectomy, which was facilitated by use of epidural morphine. For the epidural group, the mean (+/-SD) surgical time was 69.2 +/- 10.2 minutes compared with 124.4 +/- 21.2 minutes for mares not administered morphine. Less systemic sedation was required for mares administered epidural morphine. Conclusions: Minimal ovarian manipulation was required to apply the stapler, hemorrhage was slight, and none of the mares had complications. Epidural morphine provided effective analgesia, improving patient comfort, and reduced the sedation needed to perform ovariectomy. Conclusions: Endo-GIA II staples are an efficient method for ovariectomy in normal mares. Epidural morphine should be considered to facilitate ovariectomy because less sedation and local anesthetic administration is required.

The research conducted a clinical trial to determine the efficiency of using the ENDO-GIA staple device and ENDO-Catch pouches to perform ovary removal in horses. They also evaluated the effectiveness of an epidural morphine sulfate for pain relief during the procedure.
Methodology
The study relied on a randomized clinical trial design and used ten mares that had normal ovaries. The researchers employed an Endo-GIA II stapler for amputating the ovaries bilaterally and the Endo-Catch II pouches for retrieval, both tools are produced by the United States Surgical Corp.
The trial divided the mares into two groups. One group had five mares who were administered epidural morphine; and the other group consisted of the remaining five mares who were not given epidural morphine. Variables such as the duration of the procedure, the quantity of lidocaine necessary to numb the ovarian pedicle, and the level of sedation were compared between these two groups.
Results
- The study found that the Endo-GIA II stapling device was an easy and efficient tool to perform the ovary removal.
- For the group administered with epidural morphine, the average surgical time was notably less (approximately 69.2 minutes) compared to the group that did not receive morphine (around 124.4 minutes).
- The group that received epidural morphine also required less systemic sedation.
- Hemorrhage was minimal, and none of the mares experienced complications.
Conclusion
The findings from this study indicate that using the Endo-GIA II staples is an efficient method for ovary removal in normal mares. Moreover, the use of epidural morphine seems beneficial as it offers effective pain relief, thus improving the comfort level of the patients. Reduced sedation and local anesthetic administration were also noted, which suggests that epidural morphine could facilitate ovary removal procedures among mares.
