A 5-year old intact female lutino cockatiel presented for a chronic non-reducible hernia in the right flank. The bird had been treated unsuccessfully via centesis and drain placement. Upon presentation, the cockatiel had moderate coelomic distention and a 3-4 cm abdominal hernia in the right flank. Exploratory coelomotomy was performed to diagnose the cause of the hernia. Significant findings included multiple fibrinous adhesions on the gastrointestinal and reproductive tracts, cystic right oviduct, impacted left oviduct, and left ovarian cysts. A bilateral salpingohysterectomy was performed. The ovarian cysts were drained and removed. The coelomic cavity was closed. A skin incision over the hernia revealed a subcutaneous cystic sac and leaking right abdominal air sac. The cystic sac was removed. The air sac was sutured closed before repairing the body wall. The cockatiel recovered from anesthesia uneventfully and was discharged two days later. The patient did not experience recurrence of the hernia.
