Laparoscopic cryptorchidectomy using a resorbable self-locking loop device in dorsally recumbent horses.

Abstract: To report the use and feasibility of a self-locking resorbable loop device for cryptorchidectomy. Methods: Clinical prospective study. Methods: Twenty horses. Methods: Horses suspected to have an abdominal testicle/s after admission work-up were enrolled. Horses were anesthetized in dorsal recumbency and a standard laparoscopic technique was performed. The looped device was inserted into the abdomen, glided around the testis/cord and tightened. Then, the spermatic cord was transected prior testis removal. Surgical procedure details and remarks, perioperative complications and total surgical time were recorded. Short- (>3 weeks) and long-term (>6 months) follow-ups were obtained by telephone questionnaire. Results: Median total surgical time was 67 min (range: 43-189 min) and significantly shortened after the first four horses. The loop device was easily glided around 13/20 abdominal testes and required more time and technical skills around larger testes (≥3 years). Excellent intraoperative hemostasis was achieved in 17 horses. Three horses demonstrated mild intraoperative bleeding that required retightening, device replacement or adding a second device, respectively. Three horses developed mild postoperative hemoabdomen identified ultrasonographically and were successfully managed medically. Follow-up revealed no significant complications related to the procedure. One horse was euthanized for colic 4 months after surgery and one died of hemolytic shock 17 months postoperatively. Conclusions: This device represents another method to perform equine cryptorchidectomy that requires minimal training and laparoscopic expertise but demands knowledge of the device and application to prevent complications. Conclusions: Laparoscopic cryptorchidectomy using this device is an alternative technique for horses <3 years.

Summary

This research solely focuses on implementing a self-locking resorbable loop device for cryptorchidectomy in horses. The study aimed to evaluate this new method’s feasibility and efficiency by recording the surgical procedure’s details, complications, and total time. The outcomes revealed the technique as a viable solution for horses less than 3 years old.

Research Methodology

  • In this clinical prospective study, twenty horses suspected of having an abdominal testicle due to admission work-up were examined.
  • Horses were put under anesthesia and a standard laparoscopic technique was applied.
  • The self-locking resorbable loop device was used in the procedure. It was inserted into the abdomen, adjusted around the testis/cord, and then tightened.
  • The spermatic cord was cut prior to the removal of the testis.
  • The surgical procedure’s details and remarks, any complications during the procedure, and the total surgical time were meticulously recorded.
  • Follow-up data was collected for short-term (over 3 weeks) and long-term (over 6 months).

Results

  • The median total surgical time was found to be 67 minutes, with the maximum span extending to 189 minutes. The surgical time was significantly shortened after the first four horses.
  • The use of a loop device was facile with 13 out of the 20 abdominal testes. However, it demanded more time and technical skills for larger testes (equal to or greater than 3 years).
  • Excellent intraoperative hemostasis was achieved in 17 horses. Three of the horses underwent mild intraoperative bleeding that required the loop device to be retightened, replaced, or added with a second device.
  • Three horses developed mild postoperative hemoabdomen, identified via an ultrasonogram, and were managed medically.
  • There were no significant complications related to the procedure documented in the follow-ups. One of the horses was euthanized due to colic 4 months following the surgery while another passed due to hemolytic shock 17 months postoperatively.

Conclusions

  • The study showed that the resorbable loop device offers yet another method for equine cryptorchidectomy. It predominantly requires knowledge of the device and its application to prevent complications rather than substantial training and laparoscopic expertise.
  • The cryptorchidectomy using this device is a viable alternative technique for horses younger than 3 years.
