2例犬胸部食道梗阻的诊治

Diagnosis and Treatment of Thoracic Esophageal Obstruction in Two Dogs

犬胸部食道梗阻大多因吞咽了边缘锐利的骨头、金属、玩具等异物而引起,以多涎、呕吐和频繁的吞咽动作,以及呼吸困难为特征。完全阻塞的病例,液体和固体食物吞咽后立即返流,不完全阻塞的病例,流质食物可通过梗塞部位。体积较大的异物压迫气管会造成呼吸困难。尖锐的异物可以造成食道穿孔,导致胸膜炎发生,患犬表现为厌食、发热和胸腔积液,甚至出现感染性休克。本文报道了2例犬胸部食道完全梗阻的诊断和治疗过程。结果表明,X线检查对识别异物和确定阻塞部位有特殊作用;对患病动物及早实施开胸术和食道切开术取出异物,配合术后抗感染治疗和静脉营养支持,预后良好。

Most of Canine thoracic esophageal obstruction is caused by swallowing sharp bone,metal,toys and other foreign bodies,which are characterized by polysialia,vomiting,frequent swallowing and dyspnea.In the case of complete obstruction,liquid and solid food can reflux immediately after swallowing.In the case of incomplete obstruction,the liquid food can pass through the infarct site.The pressure of the trachea by bigger-sized foreign bodies can cause dyspnea.Sharp foreign bodies can cause perforation of esophagus,further bringing about pleurisy,and suffered dogs showed symptoms such as anorexia,fever and pleural effusion,even septic shock.This paper reported the diagnosis and treatment of complete obstruction of thoracic esophagus in two dogs.The results showed that X-ray examination had critical effect on identifying foreign bodies and determining the blocking area.The prognosis of the canine was good,which was early performed by thoracotomy and esophagotomy,combined with postoperative anti-infect treatment and nutritional support via venous approach.
