Case description- A 2 years old common mynah (Acridotheres tristis) of unknown sex, weighing 180 g, with history of lack of appetite and depression was referred to the veterinary hospital of Lorestan University.
Clinical findings- Clinical signs included: anorexia, depression and diarrhea. Lateral radiograph showed a soft tissue opacity foreign body within the body with its distal end, seemingly in the ventriculus and its proximal end extending to the thoracic esophagus.
Treatment and outcome- Because the foreign body can cause obstruction, the decision was made to remove the foreign body by surgery technique. The feathers at the incision site were plucked and the skin was prepared in the usual surgical procedure. An incision (2cm) was made along the ventral midline and after tenting the abdominal musculature and O2 was distributed in the abdominal cavity. Then ventriculus was approached through an initial stab incision in the mid-portion of the ventricular and the foreign body, which was a sewing elastic band, was pulled out slowly with a small mosquito hemostat.
Clinical relevance- For removing of a foreign body in GI tract of birds several techniques were reported that depended on size, composition and position of FB in GI tract. In this mynah, due to the position of FB in ventricular cavity, celiotomy method was used. In abdominal surgery changes in the mechanical properties of the respiratory system, may reduce the volume of breathing. So, for preventing of hypoxia, using of O2 is useful.
