## Overview Inguinal hernia occurs when intestine passes through the inguinal canal into the scrotum, most often in stallions. A reducible hernia may be present from birth or acquired. If the intestine becomes trapped and strangulated, it is a surgical emergency with colic and a firm, painful, non-reducible swelling. ## Causes Congenital enlarged inguinal ring or acquired herniation, often after breeding or trauma. ## Diagnosis Palpation of scrotal swelling, ultrasound, and signs of colic if strangulated. ## Treatment Manual reduction under sedation for uncomplicated cases. Emergency surgery for strangulated hernias. Castration is often performed at the same time in stallions. ## Recovery and Prognosis Good if reduced before bowel compromise. Strangulated cases have a more guarded outlook. ## Prevention None for congenital predisposition. Prompt attention to scrotal swelling.
