A 6-week-old intact female coton de Tulear dog presented to a veterinary teaching hospital (VTH) internal medicine service for dysphagia that was persistent since birth. The patient was diagnosed with cricopharyngeal achalasia based on a fluoroscopic swallow study. To facilitate surgical intervention, a percutaneous endoscopic gastrostomy (PEG) tube was placed to bypass the upper esophageal sphincter and provide nutritional support until the dog was larger. At 6 mo of age, the dog underwent unilateral cricopharyngeal and thyropharyngeal myectomy. Marked improvement in dysphagia was noted immediately postoperatively. Improvement in dysphagia persisted in this dog, with continued marked improvement in clinical signs noted 1 y postoperatively. Key clinical message: Cricopharyngeal achalasia can be successfully managed with surgical intervention with a good long-term prognosis. Before surgical intervention, nutritional support is of critical importance. A combined procedure of cricopharyngeal and thyropharyngeal myectomy may be associated with outcomes superior to those of alternative procedures.
一只 6 周龄未去势的雌性科顿德图莱勒犬因自出生以来持续性吞咽困难而到兽医教学医院（VTH）内科就诊。根据荧光透视吞咽研究，该患者被诊断为环咽肌失弛缓症。为了便于手术干预，放置了经皮内镜胃造口术（PEG）管以绕过食管上括约肌并提供营养支持，直到狗长大一些。在 6 月龄时，狗接受了单侧环咽肌和甲状旁腺肌切除术。术后立即注意到吞咽困难明显改善。该犬的吞咽困难持续改善，术后 1 年临床症状持续显著改善。关键临床信息：环咽肌失弛缓症可以通过手术干预成功治疗，预后良好。手术干预前，营养支持至关重要。环咽肌和甲状旁腺肌切除术的联合手术可能与其他替代手术相比具有更好的结果。
