Upper Esophageal Sphincter Dilation for Recalcitrant Dysphagia Secondary to Dermatomyositis

Abstract

Dermatomyositis is a rare multisystem autoimmune disorder occasionally accompanied by dysphagia. It is typically treated with immune modulating agents; however, dysphagia is often unresponsive to these. Previous reports have demonstrated the utility of videoflouroscopy and manometry in understanding the etiologies of dysphagia to inform a procedural target, historically the cricopharyngeus muscle. We present a case of dermatomyositis and dysphagia resistant to medical management in a patient found by videoflouroscopy and manometry to have severe oropharyngeal dysphagia, esophageal dysmotility and a cricopharyngeal web. We demonstrate the utility and safety of upper esophageal sphincter dilation by transnasal esophagoscopy even in the setting of multifactorial dysphagia.
