This appears, unfortunately, to be the fairly classic pharyngoesophageal problem that often develops in this disorder. See:

            Abstract 
  Background: Esophageal motility is often disturbed in patients with myotonic dystrophy. The esophageal motor derangement pattern and its correlation with esophageal and peripheral motor symptoms is not well defined. Our aims were to evaluate: 1) pharyngo-esophageal motor abnormalities in these patients; 2) the relationship between motor involvement and clinical manifestations; and 3) the correlation between pharyngo-esophageal motility abnormalities and peripheral neuromuscular involvement. Methods: We compared data from 18 patients and 18 healthy controls. Neuromuscular affectation was quantified with a five-point muscular disability rating scale. Pharyngo-esophageal symptoms were assessed with a directed questionnaire, whereas motility was evaluated by means of manometry. Results: Myotonic dystrophy patients had diminished pharyngeal contraction amplitude, upper esophageal sphincter basal pressure, and esophageal body contraction amplitude compared with the control
 group (P < 0.001). No signs of esophageal myotony were evident. Simultaneous esophageal waves after more than 40% of liquid swallows were found in 80% of patients. No relationship between esophageal manometric alteration and esophageal or peripheral motility symptoms was elicited. Conclusion: In patients with myotonic dystrophy pharyngo-esophageal motility is severely deranged in both amplitude and coordination. These abnormalities may be present even if symptoms referred by the patient or the severity of the disease is not remarkable.
