Standing laparoscopic inguinal hernioplasty using cyanoacrylate for preventing recurrence of acquired strangulated inguinal herniation in 10 stallions.

This research article presents a surgical technique using cyanoacrylate glue for inguinal hernioplasty in horses and sees its application and effectiveness in preventing recurrent inguinal herniation in stallions that previously acquired strangulated inguinal hernia.

Procedure of the Surgical Technique

• This research conducted the study on 10 stallions with a history of Strangulated Inguinal Hernia (SIH).
• The unique method of Hernioplasty is conducted on standing horses via four laparoscopic (minimally invasive surgery involving a small incision and the use of a laparoscope) portals.
• The mesorchium (a part of the spermatic cord that approximate the testicle) was retracted using an instrument called Babcock forceps.
• A flexible polyethylene extension tube was introduced through the sheath of a laparoscopic needle and then n-butyl-2-cyanoacrylate (a type of glue that adheres rapidly) was injected into the inguinal canal, including its margins. Another Babcock forceps was used at the same time to prevent the cyanoacrylate from spreading too deep into the tissue.
• The craniolateral parts of the vaginal ring were compressed until full adhesion between the visceral (internal organs) and parietal walls (outer layers) was achieved.
• In two horses, the lateral part of the vaginal ring was sutured before gluing. A contralateral approach (involving the opposite side) was used to check the caudomedial part of the vaginal ring.

Results and Conclusion

• The research found no recurrence of inguinal hernia in the stallions, up to four years after the surgery.
• The procedure was considered safe as no major complications were reported and an excellent cosmetic outcome was observed, meaning that the horses did not show noticeable negative physical changes from the surgery.
• All the horses could be used for their intended purpose post-surgery and those that were used for breeding remained fertile, proving the procedure did not affect their reproductive capabilities.
• The research concluded that standing inguinal hernioplasty using cyanoacrylate is an efficient and safe method for closing the vaginal ring in stallions, thus revealing its potential as an effective surgical intervention for preventing recurrence of strangulated inguinal hernia.
