Atresia anal associada a fístula retovaginal em cadelas : relato de três casos

Abstract

The objective of this work is to report the surgical correction, the operative complications developed and the therapeutic management instituted in 3 dogs diagnosed with type IV anal atresia. The three puppies were treated and monitored until surgical discharge. Among the clinical signs initially presented were: tenesmus, loose stools and abdominal distension. The diagnosis was based on physical examination and complementary tests, such as abdominal radiography. Surgical treatment was based on transposing the fistula to the correct anatomical location of the anal opening, and proved to be effective in the 3 animals reported, as it allowed the maintenance of the normal functions of the patients' genitourinary and gastrointestinal tracts. Postoperative management consisted of antibiotics, analgesics, laxatives and dressings. Thus, the postoperative complications observed were: tenesmus and intestinal constipation. No suture dehiscence, anal stenosis or fecal incontinence were observed. Therefore, it is concluded that early diagnosis of anal atresia and corrective surgery can contribute to better chances of survival for the patient. However, postoperative complications are common in dogs with anal atresia and may be associated with a worse prognosis in some of them.
