Etiological treatment of esophageal achalasia are absent. None of the currently available treatment methods can restore normal esophageal peristalsis and the functionality of the lower esophageal sphincter, thereby alleviating dysphagia and other symptoms of achalasia. Therapeutic procedures currently used for the effective treatment of achalasia of the esophagus are represented by laparoscopic Heller's myotomy and endoscopic balloon dilatation of the esophagus. According to the literature, Heller's myotomy is considered as a method of choice in children, since it provides more reliable results in comparison with pneumatic expansion during prolonged observation. Peroral endoscopic myotomy (POEM) is a new endoscopic method for the treatment of esophageal achalasia, first reported by P. Pasricha in experiment, and then H. Inoue performed this operation in adult patients. There are only a few studies on the use of POEM in children and adolescents. Existing studies have demonstrated the feasibility of this procedure in children, low level of complications and excellent results with short-term observation. Several studies have reported high efficacy in the use of POEM in children, ranging from 90% to 100%. Reports of the occurrence of complications after POEM in children are sporadic and are represented by the formation of subcutaneous emphysema, carboperitoneum, retroperitoneum and mediastinal emphysema. Obviously, detailed studies with longer observation are required before the role of POEM in the treatment of esophageal achalasia in children can be established. If preliminary results are confirmed, POEM can be a real alternative to Heller's myotomy in pediatric patients. This study is intended to explore the potential and safety of the use of POEM for the treatment of achalasia in children based on a review of existing data in the scientific literature.
