Use of a temporary incontinent end-on colostomy in a cat for the management of rectocutaneous fistulas associated with atresia ani

A 2 1/2-month-old cat was evaluated for the presence of multiple draining tracts ventral to the tail of 8 days duration. Clinical and radiographic examination revealed that the cat had rectocutaneous fistulas and type II atresia ani. The cat underwent a temporary end-on colostomy for faecal diversion. Sixty days after surgery and after the fistulas resolved the animal underwent a second surgery for colostomy closure and anal reconstruction. Two years after surgery the cat was reported to be in good health with no faecal incontinence.
