Pharyngoesophageal dysphagia and gastroesophageal reflux.

Pharyngoesophageal dysphagia occurred in 51.3 percent of 1,000 consecutive patients with gastroesophageal reflux. Aspiration, secondary to food obstruction, occurred in 30 percent of these patients, and some developed significant secondary respiratory symptoms. The site of obstruction was localized to the cricopharyngeus by timing the interval from swallow to obstruction. Cricopharyngeal incoordination was demonstrated in 20 of 52 patients studied by high speed esophageal manometry. Surgical correction of gastroesophageal reflux in patients with intractable reflux symptoms was shown to be effective in relieving pharyngoesophageal dysphagia in all but a small number of patients with very severe symptoms. In those with persistent dysphagia cricopharyngeal myotomy at a later stage was effective in giving relief.
