Abstract

Introduction Primary achalasia is an idiopathic motility disorder of the esophagus characterized by esophageal aperistalsis and incomplete relaxation of the lower esophageal sphincter (LES) in response to swallowing. The gold standard diagnostic method in adults is high-resolution manometry (HRM). Diagnostic criteria in adults are also used in children, but some HRM normal values may change depending on age.Case Report A 15-month-old girl was admitted to the hospital for evaluation due to persistent vomiting since birth. Vomiting included what she ate regardless of the amount of food she consumed. Barium esophagography revealed barium retention, esophageal dilatation, and a "bird's beak appearance" in the distal esophagus. Esophagogastroduodenoscopy revealed stenosis in the lower esophagus and bubbles at the esophagogastric junction.In HRM, the resting LES pressure was 43.4 mm Hg, there was pan-esophageal pressurization with 60% of swallows and no normal peristalsis. The patient was diagnosed with type II achalasia based on the Chicago 3.0 classification.First, the tube was inserted to ensure adequate nutrition of the patient, and approximately 4 months later, when the patient was 10 kg, the peroral endoscopic myotomy (POEM) procedure was performed.No complications developed during and after the procedure. At the 6th month after treatment, the patient was completely asymptomatic and her weight was within normal limits for her age.Conclusion POEM is an effective and safe method in the treatment of pediatric patients with idiopathic achalasia.
