|q2= When can you repair this type of injury?

|q2= When can you repair this type of injury?

|a2= Where foaling and injury has occurred less than 3 hours before examination, immediate repair can be investigated but is rarely indicated. Usually severe bruising and laceration are present and repair should be delayed until granulation of the area occurs in 6–8 weeks or even longer.

|q3= What two common surgical techniques can be used in this repair and how do they differ?

|a3= (1) The Aanes technique is a two-stage repair: stage 1 reconstructs the rectovestibular shelf but leaves the perineal body open; in stage 2, the perineal body is closed 3–4 weeks later.

(2) The Goetze technique is a single-stage operation: the principle is to evert the rectal mucosa into the rectum and vaginal mucosa into the vagina with a form of purse string suture.
