title: Long-term outcome of peroral endoscopic myotomy for achalasia treatment in a 9-year-old female patient.
abstract: Achalasia is a primary motility disorder with incomplete lower esophageal sphincter relaxation; it has an annual incidence of 0.11 cases per 100 000 children. Peroral endoscopic myotomy (POEM) is a new endoscopic treatment method for achalasia. Reports about POEM in pediatric patients are rare. We herein report the case of a 9-year-old female patient with achalasia who underwent POEM. The patient underwent endoscopic balloon dilatation because medication was not effective at a previous hospital; however, endoscopic balloon dilatation was not effective either. She then underwent successful POEM upon admission at our hospital. The patient was symptom-free at 2 years postoperatively with no signs of esophagitis in the absence of proton-pump inhibitor therapy.
