Onset timing of delayed complications and criteria of follow-up after operation for esophageal achalasia

摘要: Background. The purpose of this study was to define the length follow-up necessary obtain definitive results Heller myotomy for therapy esophageal achalasia and modalities long-term follow-up. Insufficient myotomy, periesophageal scarring, gastroesophageal reflux esophagitis are most common late complications operation achalasia. Columnar-lined esophagus with or without dysplasia cancer can further complicate postoperative esophagitis. Because progressive worsening time has been reported, we assessed timing appearance these complications. Methods. Since 1973, 129 patients submitted were clinically objectively followed up. Mean 97.4 months (range, 12 268 months). Of patients, 42 up less than 5 years (17 voluntary drop outs, 10 reoperations, 3 deaths, in follow-up), 47 more years, 26 15 2 20 years. onset symptoms related evaluated as development cancer.
