Oesophageal impaction in a Canada goose (Branta canadensis).
An oesophageal impaction, consisting of plant material and nylon fishing line, and alimentary parasitism were diagnosed and treated in a Canada goose. At presentation the bird was non-ambulatory with flaccid neck muscles, lethargic, emaciated, dehydrated and had watery brown to green faeces. Palpation of the neck revealed a solid tubular mass ventrally in the mid-cervical region with gritty material cranial to it. Radiographs disclosed an oesophageal mass containing seed or grit-like radio-opaque material, and dilated cranial oesophagus containing radio-opaque material. Laboratory investigations revealed non-regenerative anaemia, heterophilia, lymphopenia, hypoproteinaemia, and many strongyle eggs in faeces. Treatment included supportive therapy, oesophageal gavage, oesophagotomy and drug therapy. The bird recovered and was released 27 days after initial presentation.
