Abstract
Purpose
The radiological features of achalasia of the esophagus are well known and have been described. However, very little is known concerning the natural history of this disease. We aimed to determine the evolutive radiological changes of the esophagus in a group of patients with achalasia who had not previously undergone any treatment.
Methods
We undertook a prospective study of 14 patients with achalasia from a group of 205 patients. They included 9 women and 5 men who did not receive any treatment at the initial diagnosis. Two radiological parameters were evaluated: (a) the maximal internal diameter of the middle third of the thoracic esophagus in millimeters and (b) the internal diameter of the esophagogastric junction in millimeters.
Results
At a mean follow-up of 5-years without any treatment, there was a significant increase in the diameter of the thoracic esophagus, with a rate of “dilatation” of 6.1 mm/year. In addition, there was a significant decrease of the internal diameter of the esophagogastric junction, with a rate of “stenosis” of 1 mm/year. The lower esophageal sphincter was hypertensive in all with an incomplete relaxation.
Conclusion
These results suggest that there is a progressive deterioration in the radiological parameters of the esophagus in patients with achalasia not treated over a 5-year period of observation.
