Evaluation of a motorized morcellator for laparoscopic removal of granulosa-theca cell tumors in standing mares.

This research article discusses the usage of a motorized morcellator for laparoscopic removal of granulosa-theca cell tumors (GCTs) in mares, with the outcome showing positive results and minimal complications.

Research Methodology

• Seven mares, ranging from ages 4-15, with unilateral GCTs were the subjects examined for this study.
• The GCT tumor sizes were determined via transrectal palpation and ultrasonography.
• The mares were kept standing and sedated while three laparoscopic portal sites were established in the paralumbar fossa.
• The GCT was observed laparoscopically; afterwards, the mesovarium was desensitized, the ovarian pedicle was transected with a LigaSure device, and the ovary was grasped with forceps.
• The ovary was then cut into cylindrical blocks using a motorized morcellator, and these tissue blocks were removed through the laparoscopic sleeve.
• Data was collected on the outcome by conducting telephone interviews with the owners 6-40 months post-surgery.

Results

• The median measurement for the GCTs was estimated at 17 cm based on ultrasonography, with a range of 10-22 cm noted.
• The surgical time duration was between 2 and 4.5 hours.
• No surgical complications were reported during the operations.
• Post-surgery, two mares developed mild subcutaneous emphysema at the portal sites.
• The recovery period was brief and the owners were happy with the cosmetic results. Furthermore, there were no reoccurrences of the clinical signs associated with GCTs.

Conclusions

• The usage of a motorized morcellator effectively facilitated the piecemeal removal of large GCTs through a relatively minor laparoscopic portal.
• The low incidence of surgical complications and favorable cosmetic outcomes were significant positive results.
• The study demonstrates that a motorized morcellator is a safe and minimally invasive method for performing laparoscopic removal of GCTs in mares.
