Case Description:
A 4-month-old Hampshire ram underwent open right inguinal herniorrhaphy and unilateral castration following herniation that developed after a kick injury. Seven months later, the ram was reevaluated because of scrotal swelling of 1 month's duration as well as suspected left inguinal hernia.
Clinical Findings:
The ram had marked scrotal swelling. Palpation of the left testicle revealed no abnormalities. Ultrasonographic examination revealed heterogenous tissue within the cranial and medial portions of the scrotum with pronounced accumulation of hypoechoic fluid at the scrotal apex. Examination findings indicated left-sided indirect inguinal herniation of omentum.
Treatment And Outcome:
To preserve fertility, left inguinal hernioplasty without castration was performed. The ram was anesthetized and placed in dorsal recumbency, and laparoscopic abdominal evaluation revealed omental entrapment within the left inguinal ring. The omentum was removed, and a polypropylene mesh was secured over the internal inguinal ring with an articulating hernia stapler. Following mesh placement, a dorsally based peritoneal flap was elevated and secured over the mesh repair. The ram recovered well from surgery; there was no repeated herniation following the surgical correction, and the ram was able to breed successfully without complication.
Clinical Relevance:
Laparoscopic mesh hernioplasty can be successful in rams with inguinal hernias when preservation of fertility is preferred.
