Staged endoscopic ventricular foreign body removal in a gyr falcon (Falco rusticolus).

A large ventricular foreign body was identified on radiographs in a captive-bred gyr falcon (Falco rusticolus) that was presented for paresis and swollen abdomen. On endoscopic examination, a large shiny mass was visible in the ventriculus. An ingluviotomy was done, and pieces of the mass, which consisted of a ball of artificial grass fibers, were removed by using a rigid endoscope and grasping forceps. Subsequently, 4 more ingluviotomies were required to gain endoscopic access to the ventriculus and to allow staged removal of the mass in a piecemeal fashion. Feeding the falcon a feathered quail and allowing it to cast naturally removed the remaining fibers of the mass. No deleterious effects were observed in the bird.
