Surgical Repair of Congenital Rectovaginal Fistula and Atresia Ani in a Lamb

A five days old lamb was presented with a history of voiding faeces through the vulva, with tenesmus since birth. Clinical examination revealed presence of faeces in the vaginal region, abdominal distension, discomfort on abdominal palpation and absence of anal opening. The case was tentatively diagnosed as a rectovaginal fistula with atresia ani and subjected to surgical intervention. A linear skin incision made from the base of anal opening to the dorsal wall of the vulva. The Rectal wall was identified and separated from the communication. The Rectum was sutured to the skin at the anal opening and anus was reconstructed. Postoperatively animal was treated with Fluids and antibiotics. Animal recovered uneventfully.
