A 10-year-old neutered male Labrador Retriever dog was diagnosed with idiopathic megaesophagus. Despite receiving conventional treatments including elevated feeding, the dog showed repeated regurgitation and aspiration pneumonia, consequently developing weight loss and severe malnutrition. For the purpose of controlling regurgitation, an esophagostomy tube was placed for draining the esophageal fluid. Additionally, an esophagogastric tube was placed for nutritional support. After tube placement, the average frequency of regurgitation was reduced from 2.4 times a day to 0.1 times a day. The nutritional state of the dog improved gradually, and the body weight increased from 18.5 to 27.9 kg. The dog died on day 951, and necropsy revealed a gastric ulcer (2.5 cm in diameter), presumably esophagostomy tube-induced injury. This case report suggests that patients with idiopathic megaesophagus and persistent regurgitation might benefit from esophageal drainage through an esophagostomy tube.
一只10岁已绝育的雄性拉布拉多寻回犬被诊断患有特发性巨食管症。尽管接受了包括抬高喂食在内的常规治疗，但这只狗仍反复出现反流和吸入性肺炎，进而导致体重减轻和严重营养不良。为了控制反流，放置了一根食管造口管以引流食管内的液体。此外，还放置了一根食管胃管用于营养支持。放置管子后，反流的平均频率从每天2.4次降至每天0.1次。这只狗的营养状况逐渐改善，体重从18.5千克增加到27.9千克。这只狗在第951天死亡，尸检发现一个直径为2.5厘米的胃溃疡，推测是食管造口管造成的损伤。本病例报告表明，患有特发性巨食管症且持续反流的患者可能会从通过食管造口管进行食管引流中获益。
