Surgical management of atresia ani et recti with congenital absence of tail (anury) in a male buffalo calf

Abstract

A day old male buffalo calf was presented with complaints of abdominal straining and lack of defecation. On examination it was found that the calf had no tail with blunt posterior sacral margin and absence of anal opening. The case was diagnosed as congenital anury with atresia ani et recti. Cruciate incision was made at the anal area to create an anal opening by sedating the animal with 0.1 mg/kg of xylazine administered intravenously and under local infiltration with 2% lidocaine which facilitated passing of plenty of meconium. Surgical wound was closed in simple interrupted pattern with nylon. The animal was administered ceftriaxone for 5 days, meloxicam for 3 days and antiseptic dressing with HIMAX ointment had an uneventful recovery.
