Achalasia. A possible late cause of postpolio dysphagia

Abstract

The aim of this paper is to describe a patient with severe postpolio problems who developed achalasia. A 66-year-old patient came to our observation for severe dysphagia. He had suffered from paralytic poliomyelitis at the age of 7 months and had severe residual deficits. At the age of 62 he presented with sudden pain localized in the distribution of the C4 and C5 dermatomes and an inability to abduct the left arm. At the time, he experienced only occasional and mild dysphagia; his esophagus was not dilated and emptied normally. Over the following months his muscular function improved, but dysphagia worsened. We found a megaesophagus with a sigmoid appearance and the manometric features of achalasia. Pneumatic dilatation produced good resolution of dysphagia. A year later manometry showed the reappearance of peristalsis after all wet swallows. In patients with postpolio dysphagia, the possible presence of achalasia must be considered.
