OBJECTIVE: To evaluate signalment, clinical findings, surgical treatment, and long-term outcomes in puppies and kittens after surgical repair of various types of atresia ani (AA) with or without concomitant anogenital or rectogenital malformations.
DESIGN: Retrospective case series.
ANIMALS: 11 puppies and 1 kitten.
PROCEDURES: Medical records of 2 veterinary teaching hospitals were reviewed for puppies and kittens that underwent surgical treatment for AA. Information regarding signalment, diagnosis, surgical procedures, follow-up time, and outcome was recorded. A previously described classification scheme was used to classify AA as type I, II, III, or IV. Follow-up times and outcomes were evaluated.
RESULTS: AA was classified as type I in 3 animals, type II in 6, and type III in 3. Nine of 12 patients had anogenital or rectogenital malformations; 8 of these had rectovaginal fistulas. Eleven animals underwent in situ anoplasty, and 1 underwent surgery in which the rectovaginal fistula was used for anal reconstruction. Six also underwent balloon dilation for treatment of anal stenosis, and revision anoplasty was performed in 5. All patients with type I or II AA survived ≥ 1 year. Two puppies with type III AA were euthanized 3 and 40 days after surgery. Follow-up time for the remaining 10 patients ranged from 12 to 92 months, and 3 had fecal incontinence.
CONCLUSIONS AND CLINICAL RELEVANCE: Surgical repair of type I or II AA resulted in long-term survival and fecal continence in most cases. Although numbers were small, patients with type III AA had poorer outcomes than did those with type I or II AA.
