True Coelomic Hernia and Herniorrhaphy in a Yellow-crowned Amazon Parrot ( Amazona ochrocephala)

An 8-year-old male yellow crowned Amazon parrot ( Amazona ochrocephala) was presented for an 8-month history of intermittent regurgitation, anorexia, and lethargy along with a 3-week history of a soft tissue mass cranial to the vent. Examination revealed a small soft tissue mass, approximately 2 cm in diameter, within the body wall of the coelomic cavity with no discoloration of the surrounding tissue. Full body computed tomography (CT) revealed a defect in the body wall on the ventral coelom from the right paramedian location extending to the right side, which contained intestines. Surgical exploration allowed for reduction of the coelomic hernia, which was encased in fibrous tissue and contained a well-vascularized and motile loop of bowel. The hernia sac was excised before closing the body wall in a simple interrupted pattern. Three months postoperatively, the bird was reported to be doing well at home with no further episodes of regurgitation or anorexia.
