Achalasia of the cardia is a disorder of esophageal motility characterized by loss of peristalsis and failure of relaxation of the lower esophageal sphincter (LES) at swallowing. Treatment is directed toward symptomatic relief of the disorder by disrupting the circular muscle fibers of the lower esophageal sphincter . This can be achieved with surgical cardiomyotomy or balloon dilation. The aim of this study was to report the experience with pneumatic ballon dilation for treatment of achalasia in children in Pediatric Gastroenterology and nutrition Unit of Miguel Perez Carreño Hospital (Caracas, Venezuela), in the period between January, 2000 on December, 2007. Patients and method: 8 patients with radiological, manometric and endoscopic diagnosis of achalasia were studied prospectively, they were submitted to pneumatic dilation and later to a clinical and manometric follow-up with the objective of register their response to the treatment. A score of severity was calculated for the digestive symptoms, according to the proposed for Kim, et al. Before the procedure and later a month and the 6 months, the percentage of improvement was calculated with regard to initial one. Results: The average of age was of 8,3 years. There was no predominance of genre. 100 % of patients presented dysphagia and regurgitation and 87,5 % malnutrition and chronic cough. The procedures werw ended without complications. 1 patient (12,5%) needed a second session of dilation for persisting with clinic. The evolution was satisfactory, with notable reduction of the symptoms to one month (87,5 %) and to 6 months (100 %). Conclusions: we think that the pneumatic expansion is a therapy cost effective, with good response to short and medium term, low morbidity and continues being the first choice therapy in the treatment of the paediatric patients with acalasia.
