ANAL ATRESIA IN PIGS – CASE REPORT

Anal atresia is a congenital malformation of the posterior intestine of pigs, characterized by the absence of a functional anal orifice and considered relevant from a clinical and productive point of view, due to the high mortality associated with the absence of surgical intervention. This study aims to report a case of anal atresia in a piglet, highlighting the clinical, diagnostic and surgical aspects involved. A three-day-old mixed-breed male pig showed no anal opening and mild abdominal distension. The clinical diagnosis indicated congenital anal atresia, and a corrective surgical procedure was performed under epidural block with lidocaine, associated with sedation with ketamine and diazepam. The technique consisted of a perineal incision, identification and traction of the rectal ampulla, followed by the preparation of a functional anal ostium and mucocutaneous suture in a separate simple pattern, using absorbable suture. The postoperative protocol included analgesia, anti-inflammatory, local hygiene, and application of healing ointment, resulting in a favorable clinical evolution, with complete healing in ten days and absence of complications. The case highlights the feasibility of surgical correction of anal atresia in pigs, emphasizing that the prognosis is directly related to the type of anomaly and the clinical conditions of the patient, in addition to reinforcing the importance of reports that expand the knowledge about congenital malformations in pig farming.
