Abdominal wall hernias are generally either congenital or acquired. Common etiologies in birds include obesity, endocrine abnormalities, trauma, and intracoelomic masses.1-7 Repair of hernias has been successful in various avian species, although most reports have been in smaller birds with minor defects.4-7 This case report describes the successful reconstruction of a large defect in the left abdominal wall of a wild brown pelican (Pelecanus occidentalis).
An immature brown pelican presented to the South Florida Wildlife Center with a large abdominal swelling, which was diagnosed as a hernia of the left abdominal wall. An initial unsuccessful attempt at repair found that there was no discernible remnant of the left abdominal wall, suggesting a congenital or traumatic etiology. Two months later, the hernia was repaired using a polypropylenea mesh implant. The absent abdominal wall was reconstructed by tacking the mesh to the linea alba, the epaxial muscles, and around the last rib and pubis. Nonabsorbable polypropyleneb suture was used in a simple interrupted pattern to secure the mesh in place. The subcutaneous tissues and skin were closed in a single layer using absorbable polydioxanonec suture in a continuous pattern. Post-surgically, an infection developed in the subcutaneous tissues at the surgical site. Exploration of the area confirmed that the mesh was not infected and was incorporated into a healthy granulation bed. After removal of infectious subcutaneous exudate, the patient recovered quickly and exhibited normal behavior in an outdoor enclosure. Three months later, the pelican was released off the east coast of south Florida.
