Twenty-seven patients with these diverticula were evaluated with respect to pathogenesis, clinical aspects, diagnostic tests, therapy, and natural history for a mean of 27 months of followup. Thirteen diverticula were midesophageal, 11 were situated in the distal third of the esophagus, and 3 were in both regions. Esophageal dysmotility was observed in 85% of patients. Specific esophageal motor disorders were more frequent in association with diverticula of the distal third than in midesophageal diverticula, suggesting that they result from a pulsion mechanism. Traction was the possible mechanism in 27% of midesophageal diverticula. Endoscopic esophagitis was seen in one patient and abnormal acid reflux in 25% of the cases, mainly in patients with distal diverticula. Distal diverticula presented with more severe symptoms than did midesophageal diverticula, and 27% of those required surgical treatment. Patients with midesophageal diverticula seem to have a better prognosis than those with more distal disease.
