Acquired megaesophagus of suspected neuromuscular origin was diagnosed in a six year old Holstein cow. The dilatation was restricted to the lower cervical esophagus. Signs included projectile regurgitation of chewed ingesta at variable periods of time after swallowing, nasal discharge of mucus and feed particles, and a cough. A secondary aspiration pneumonia was associated with this condition. The dilated portion of the esophagus was detected utilizing positive contrast radiography and fiberoptic endoscopy. Treatment consisted of feed management and antibiotics. Deglutition in the cow returned to normal over a three month period despite radiographic and fiberoptic endoscopic evidence of a persistent dilatation of the esophagus.
一头6岁的荷斯坦奶牛被诊断出患有疑似神经肌肉源性的后天性巨食管症。扩张仅限于颈段食管下部。症状包括吞咽后不同时间段出现的咀嚼食物喷射性反流、鼻腔排出黏液和饲料颗粒以及咳嗽。这种情况还伴有继发性吸入性肺炎。通过阳性造影剂造影和纤维内镜检查发现了食管的扩张部分。治疗包括饲料管理和使用抗生素。尽管造影和纤维内镜检查显示食管持续扩张，但这头奶牛的吞咽功能在三个月内恢复了正常。
