title: Severe dysphagia, dysmotility, and unusual saccular dilation (diverticulum) of the esophagus following excision of an asymptomatic congenital cyst.
abstract: Iatrogenic dysmotility syndromes, particularly achalasia-like conditions, occasionally complicate esophageal and paraesophageal surgery. We describe a patient who developed a very unusual (and as far as we know unreported) syndrome characterized by severe dysphagia, esophageal dysmotility (segmental simultaneous contractions of the distal esophagus), and very large saccular outpouching (diverticulum) involving the right wall of the distal half of the esophagus as a consequence of excision of an asymptomatic congenital cyst. The cyst had been discovered as an incidental finding on a preemployment chest x-ray. Our patient's dysphagia did not improve with nonsurgical treatments that are usually successful for idiopathic and iatrogenic achalasia.
