ESOPHAGEAL DILATION THERAPY FOR ACHALASIA OF THE ESOPHAGUS

Esophageal dilation therapy for esophageal achalasia has a 300-year history and remains the first-line therapy because of its low cost, progressively decreasing morbidity and mortality, and possibility of surgery for patients who do not improve. Another advantage is the feasibility of repeated trial even after surgery. The aim of this procedure is to produce a controlled tear in the lower esophageal sphincter muscle. Precise esophagographic, endoscopic, and manometric diagnosis is necessary for successful esophageal dilation therapy. In addition, the exclusion of pseudoachalasia using echogram or CT scan is important. The procedure should be carried out accurately to prevent complications. If perforation occurs, appropriate, timely management is required.
