Five dogs with rectovaginal fistula and atresia ani that had been treated by surgical correction of the malformations were studied retrospectively. Ages at presentation varied from 1 to 3 months and weight from 350 g to 7.5 kg. The histories included voiding of feces through the vulva, with or without tenesmus, usually observed after weaning. Atresia ani, presence of feces in the vaginal canal, abdominal distention, and discomfort on abdominal palpation were observed during clinical examination. Also, 3 dogs had partial tail agenesis. In all dogs, the rectovaginal fistula was isolated and transected, the vulvar and rectal defects were closed separately, and the atresia ani was repaired. Normal defecation was restored, but 1 dog had fecal incontinence that subsequently resolved. One dog died 2.5 months postoperatively, and follow-up was done on the others for periods ranging from 1.6 year to 7.7 years. Surgical correction in dogs with rectovaginal fistula and atresia ani may result in a favorable outcome, if it is done early.
对5只患有直肠阴道瘘和肛门闭锁且已接受畸形手术矫正治疗的犬进行了回顾性研究。就诊时年龄从1个月至3个月不等，体重从350克至7.5千克。病史包括断奶后通常观察到的经外阴排粪，伴有或不伴有里急后重。临床检查时观察到肛门闭锁、阴道内有粪便、腹胀以及腹部触诊不适。此外，3只犬有部分尾发育不全。对所有犬只，分离并横断直肠阴道瘘，分别封闭外阴和直肠缺损，并修复肛门闭锁。恢复了正常排便，但1只犬有大便失禁，随后症状消失。1只犬术后2.5个月死亡，其余犬只随访1.6年至7.7年不等。对于患有直肠阴道瘘和肛门闭锁的犬只，早期进行手术矫正可能会取得良好效果。
