Correct answer: E — Repair in theatre by an appropriately trained clinician

Third- and fourth-degree tears require repair by an appropriately trained clinician, usually in theatre with adequate analgesia, lighting and instruments. Skin glue or conservative healing is inappropriate for anal sphincter injury. Delaying repair to 6 weeks risks infection, incontinence and poor healing. Postnatal follow-up and pelvic floor support are also important.
