Surgical treatment of cardiac achalasia in children is still the main line of treatment with a success rate of 70-80%. Balloon dilatation is less widely used due to inappropriate size of balloons. The authors report on their experience in 11 children with cardiac achalasia over the last 7 years using balloon dilatation as the treatment of choice, 8 boys and 3 girls with ages ranging from 1.5-14 years (average 7.5 years) were investigated. One family (brother and sister) presented with no glucocorticoid deficiency or other anomalies, one patient had mental retardation, the rest had no associated anomalies. All patients presented with vomiting, 7 with dysphagia, 6 with loss of weight, 5 with recurrent chest infection and 2 with retrosternal pain. Radiological diagnosis was accurate in all patients, endoscopy with biopsy were done to confirm diagnosis and exclude other pathology, manometry yielded positive results in 4 patients. Dilatation was done under general anesthesia with fluoroscopic control, balloons were used over a guide wire (balloon sizes were 18-35 mm). Seven patients had 2 sessions and 4 had 3 sessions with radiological follow-up after the second dilatation. Follow-up ranged from 2-7 years: excellent results were achieved in 8 patients (72.7%) with disappearance of symptoms and marked radiologic improvement, 2 still have mild symptoms with overall success (90.9%), one had mild gastroesophageal reflux, controlled medically, and one had mild dysphagia but his status was improved compared to that before dilatation. One patient had recurrent dysphagia necessitating cardiomyotomy (9.1%). Results were not related to age or sex. The authors recommend balloon dilatation in children with cardiac achalasia as the treatment of choice or even as the only feasible treatment.
