Esophageal-cardia achalasia (esophageal achalasia), also known as cardia spasm and megaesophagus, is a disease caused by esophageal neuromuscular dysfunction, which is mainly characterized by lack of peristalsis, high pressure of the lower esophageal sphincter (LES) and a reduced relaxation response to swallowing movements. Clinical manifestations include dysphagia, food reflux and lower retrosternal discomfort or pain. The treatment of cardia failure can be done by both surgery and balloon dilation: 1. Balloon dilation: Gastroscopic balloon dilation is an endoscopic treatment method used for cardia failure, which is a method to relax and dilate the lower esophageal sphincter through balloon tension to improve symptoms such as choking and regurgitation of food. A balloon with a probe as the anterior guide is inserted through the mouth under fluoroscopy, allowing the probe to enter the stomach, while the balloon is fixed at the connection between the esophagus and the stomach, injecting air or fluid, and stopping the air or fluid injection when chest pain appears. It was left in place for 5 to 10 minutes and then withdrawn and repeated three times. After 5 years of follow-up after one treatment, the effective rate was 60% to 80%. The effective standard is that the dysphagia disappears and normal diet can be resumed. 2, surgical treatment: laparoscopic cardia esophageal myotomy, the lower part of the esophagus and the gastroesophageal junction circular muscle cut to release the obstruction around the cardia, with the characteristics of small trauma, safe and effective. The symptom improvement rate of surgical treatment is about 80% to 86%.
