title: Nifedipine for the poor-risk elderly patient with achalasia: objective response demonstrated by solid meal study.
abstract: We described an 84-year-old woman with symptomatic achalasia who refused both dilation and surgical treatment. She was treated with the calcium channel blocking drug nifedipine, with significant relief of symptoms. Objective evidence of response to the drug was confirmed by using an egg salad sandwich meal labeled with 99mTc-DTPA.
