On physical examination, the abdomen was distended, and there was bulging around the perineal region and severe straining. Upon palpation, the anal ring was felt at the anal area, voiding of feaces and urine from the vaginal opening was seen, while the fistula was felt upon vaginal palpation.

The patency of the newly constructed anal opening was however maintained with the use of fabricated syringe barrel. Full recovery was attained within 21 days. The animal was relived of pressure strain, pain through the surgical intervention with resultant increase in body condition score. Key words: Atresia ani, fistula, anal, palpation.
