Background: Most previously described techniques for laparoscopic inguinal hernioplasty (IH) in horses require advanced laparoscopic skills. Our objective was to describe a new laparoscopic IH technique using a surgical anchoring system.
Methods: Standing laparoscopic IH was performed unilaterally in eight experimental stallions, using the contralateral inguinal canal (IC) as a control. A polyether ether ketone harpoon was anchored in the craniolateral aspect of the vaginal ring, and an extracorporeal knot was used to fix the device. Clinical evaluation, including testicular palpation and lameness examination, was conducted before and for 4 weeks after surgery. Repeat laparoscopy was performed 28 days later.
Results: Standing laparoscopic IH was performed in all horses with a surgical time of 38 ± 12.85 minutes. In two animals, a small peritoneal tear occurred that did not require repair. No other complications were recorded. On repeat laparoscopy, all devices were in place, and the IC remained partially closed in all horses.
Limitations: The procedure was performed on normal experimental horses and has not been employed on horses that have had an inguinal hernia.
Conclusions: This new standing laparoscopic hernioplasty technique provides another potential method for simple partial closure of the IC in stallions at risk of or with history of inguinal herniation.
