  • Title: A 78-year-old man with difficulty swallowing.
    Author: Hirano I, Kahrilas PJ.
    Journal: Clin Gastroenterol Hepatol; 2011 Jun; 9(6):470-4. PubMed ID: 21320642.
    Abstract:
    CP bar is an uncommon but important cause of dysphagia in elderly people. A CP bar is often undetected during upper endoscopy and might be missed with barium radiography if adequate attention is not focused on the hypopharynx. In suspected cases, evaluation for alternative etiologies of dysphagia is important because the CP bar might be an incidental finding. Secondary causes of CP dysfunction resulting from underlying primary myopathic or neuropathic disorders should be considered before therapy. The effectiveness of dilation and surgical myotomy in alleviating dysphagia associated with CP bars has been reported in small series.
