title: Efficacy of the transthoracic modified Heller myotomy in children with achalasia--a 21-year experience.
abstract: From 1974 to 1995, 19 children with achalasia of the esophagus have been treated at our institution. Presenting symptoms included vomiting (n = 14), dysphagia (n = 13), failure to thrive (n = 6), and odynophagia (n = 1). Diagnosis was established by a barium swallow in 19, with eight also undergoing esophageal manometry. Six boys and 13 girls with an average age of 10 years (range, 1.3 to 17.6) underwent a transthoracic, modified anterior Heller esophagomyotomy (HM). Five underwent a concomitant, modified, Belsey fundoplication (BF). Follow-up ranging from 6 months to 21 years (mean, 9 years) was accomplished in all 19 patients by both office visits and telephone interviews. Early postoperative follow-up showed initial swallowing difficulty in two (14%) patients with a HM alone and in four out of five (80%) patients treated with a HM and BF. All patients (n = 5) with a HM and BF and one with a HM alone required one esophageal dilation during the first postoperative year. These initial swallowing difficulties resolved in all six patients during this first postoperative year. Late postoperative follow-up, however, indicates occasional, mild dysphagia in two out of five with an HM and BF resulting in complete relief of presenting symptoms in 17 of the 19 patients (90%). All patients rated their overall result as either excellent (68%) or good (32%) with none rating it as fair or poor. None of the 19 patients had clinical evidence of gastroesophageal reflux, although five patients had evidence of nonpathologic reflux noted during upper gastrointestinal x-ray. Recurrent vomiting, asthma, wheezing, or esophagitis symptoms have not been reported by any patients. No patients required reoperation, and there were no deaths or postoperative complications. Modified Heller esophagomyotomy is safe (0% mortality) and effective (90% relief of symptoms) in children with achalasia. A concurrent modified Belsey fundoplication results in early and late mild postoperative dysphagia that was responsive to esophageal dilation. The transthoracic, modified Heller esophagomyotomy without a fundoplication is currently our treatment of choice for achalasia in children.
