Atresia Ani Et Vulva and Rectovaginal Fistula: A Clinical Presentation in a Calf

Abstract

Anomalies are not uncommon in various domestic animal species, particularly among ruminants. However, when examining anomalies collectively, those pertaining to the urogenital system in calves and lambs are relatively infrequent occurrences. Instances of atresia ani, atresia recti, intestinal atresia, and rectovaginal fistula are more prevalent in calves. While these anomalies may manifest individually or in combination, cases involving atresia vulva are notably rare in such occurrences. The subject of this case report was a 5-day-old female Jersey cross calf, weighing 11 kg. The calf was presented to the Surgery clinic at Siirt University Faculty of Veterinary Medicine Animal Hospital, with the primary concerns being the absence of vulvar lips and issues related to anal patency. Following clinical, radiologic, and ultrasonographic evaluations, a diagnosis of atresia ani et vulva, accompanied by a rectovaginal fistula, was established. The decision was made to proceed with operative intervention. During the operative intervention, the anus hole was opened appropriately using the classical atresia sudden operative intervention method and the vulva was opened using the vaginoplasty method. During the operation, feces and urine output were checked, and the wound lips and rectovaginal fistula were sutured in accordance with the technique. Follow-up visits indicated normal defecation and urination, with the wound lips healing without complications.
