Esophageal stenosis that cannot be passed by gastroscope is mainly considered to be caused by esophageal cancer, esophagitis and other factors, and it is recommended to be examined by upper gastrointestinal imaging and using small probe gastroscope.
1. Upper gastrointestinal imaging: When the gastroscope can not pass through the patient due to esophageal cancer, barium can be consumed and upper gastrointestinal imaging can be carried out to clarify the mucous membrane of the esophagus and gastric wall through the barium revealed to determine whether there is any mucous membrane damage, rupture or obstruction, and to clarify the nature of the esophageal stenosis.
2. Small probe gastroscope: when the patient has esophagitis, it can cause swelling of the esophageal mucosa, resulting in the normal probe can not pass through normally, at this time to replace the small probe gastroscope, can pass through the narrow esophagus, to detect the esophageal and gastric mucosa situation.
When patients have this situation, it is recommended to listen to the guidance of a professional physician and not to make blind judgments on their own.
