Surgical procedures for cardia achalasia are suitable for those with obvious esophageal inflammation, initial cardia achalasia, and failed medical procedures, as follows: 1. Traditional thoracic surgery: using the open chest method, enter the chest cavity to free the esophagus, then pull off the esophageal muscle layer, while preserving the integrity of the esophageal mucosa layer, so that the esophagus becomes patent; 2. Minimally invasive surgery: 2-3 holes are made in the chest cavity, and thoracoscopic micro-operating instruments are used to cut off the external circular muscle of the esophagus longitudinally, preserving only the mucosa, so that the esophagus becomes patent.
