The main symptoms of achalasia, which is relatively rare in children and adolescents, are vomiting and progressive dysphagia due to lower esophageal strictures. As feeding is affected, it can lead to malnutrition and severe developmental disorders. Therefore, surgical treatment is often required. Due to the specific location of the lesion, which is located in the thoracoabdominal region, traditional open surgery is poorly exposed, often with long surgical incisions, trauma, and slow postoperative recovery. In order to reduce the pain of the child and improve the postoperative patient satisfaction. Laparoscopic minimally invasive esophageal and cardia myotomy + gastric fundoplication requires only 4 small holes in the abdomen. The operation is also performed under the lumpectomy with clear vision, accurate positioning and minimal disturbance to the abdominal cavity, and the child can be minimized from the surgical blow. The child can resume eating and drinking on the first day after surgery and can be discharged from the hospital in 4-5 days. Through the review and follow-up of the operated patients, all patients achieved good treatment results and the symptoms of postoperative esophageal obstruction were significantly relieved. And the surgical scar gradually faded after six months postoperatively, achieving the cosmetic effect of minimally invasive surgery.
