title: Late results following esophagomyotomy in children with achalasia.
abstract: Twenty one children with achalasia of the esophagus were treated from 1970 to 1986. There were 11 girls and ten boys (average age, 10.9 years; range, 6 months to 16 years). Diagnosis was established by barium swallow in 21 cases and confirmed by manometrics and motility studies in 14. Four children had unsuccessful dilatation (range, 1 to 16 dilatations/pt). All 21 children underwent modified anterior Heller esophagomyotomy (transabdominal in 15 and transthoracic in six). Concomitant Nissen fundoplication was performed in three. Follow-up from 1 to 14 years (mean, 6.3 years) showed complete relief of obstruction in 18 patients (86%), while three required additional procedures for persistent dysphagia. One child improved after a single dilatation, but two others eventually required a second esophagomyotomy. Three additional patients subsequently developed gastroesophageal reflux (GER), and two were managed with Nissen fundoplication; the third responded to medical management. The mortality for this series was zero. Postoperative complications occurred in nine children (42%) and was due to atelectasis and postoperative fever. Modified Heller esophagomyotomy is safe and effective in children with achalasia (mortality, 0%; relief of obstruction, 86%). Results were similar after a transabdominal or transthoracic approach. Esophageal dilatation was not an effective method of treatment. Although postsurgical barium swallow showed relief of obstruction, abnormal esophageal motility persisted, suggesting that long-term follow-up is important.
