Abstract

Atresia ani or imperforate anus is a congenital anomaly defined as the failure of development of anal opening. A two day old male buffalo calf was presented to the polyclinic with the history of not passingfaeces since birth. Based on history and clinical examination the case was diagnosed as atresia ani et recti. It was decided to perform emergency surgery to correct the condition. Surgery was done under epidural anesthesia and local infiltration analgesia using lignocaine hydrochloride 2 %. Skin incision was made in a cruciate pattern. The rectal cul-de-sac was identified by blunt dissection and was sutured to the perineal wall. Reconstruction of anal opening was done. Post-operatively animal was treated with antibiotics and anti-inflammatory drugs for five days. The skin sutures were removed on 11th post-operative day. The buffalo calf showed normal defecation pattern and made an uneventful recovery.
