fibrosis of the esophageal wall
Introduction
Introduction Esophageal wall fibrosis refers to chronic recurrent lesions of esophagitis that can cause full-thickness destruction and fibrosis of the esophagus, resulting in esophageal stricture. Esophagitis is mainly caused by swallowing pain, difficulty, heartburn and post-sternal pain. When esophagitis is severe, it can cause esophageal fistula and esophageal stricture. When the lower end of the esophagus is degenerated by inflammation and then the columnar epithelial cells of the stomach grow out, it is called Barlow's esophagus. This is the predecessor of esophageal cancer and must be tracked for a long time. Generally, the bleeding of esophagitis is mild, but it may also cause vomiting or dissolving asphalt.
Cause
Cause
Swallowing hot food, sharp foreign bodies or chewing bones, ingesting corrosive agents and other direct damage to the esophageal mucosa cause inflammation.
Physical or chemical esophagitis: Esophagitis caused by radiation exposure is called radiation esophagitis. Drugs such as quinidine, tetracycline, potassium chloride, iron, etc. stimulate the esophageal mucosa, especially tablets that are stagnant in the esophagus, can also cause esophagitis. Esophagitis caused by overheated food can quickly heal itself. Long-term use of the stomach tube, stimulate the esophagus, can also cause esophagitis.
Antibiotics are used for too long, causing infection of the esophageal mucosal fungi.

Esophagography esophageal barium meal perspective
Most occur in people over 40 years old. The lower esophageal sphincter of a normal person acts as a barrier, making it difficult for the stomach contents to flow back into the esophagus. In this sphincter dysfunction, such as esophageal hiatal hernia or other causes of this sphincter dysfunction, gastric contents can flow back into the esophagus. The gastric juice contains acid and may also contain bile or pancreatic juice. These substances have a detrimental effect on the esophagus, and cause long-term repeated inversion into the esophagus, causing inflammation, erosion, and even ulceration on the esophageal mucosa. Chronic repetitive damage can cause full-thickness destruction and fibrosis of the esophagus, resulting in esophageal stricture. The clinical manifestations are mainly heartburn, symptoms appear at night when lying down, and symptoms are relieved when sitting up. This is a typical performance. When the weight is raised, the abdominal pressure is increased, and reflux can also occur. Some foods, such as orange juice, can cause symptoms. X-ray barium meal imaging can be used as a basis for diagnosis if the expectorant can flow up and down between the esophagus and the stomach. Esophageal microscopy showed white flaky exudation, erosion, ulceration and bleeding.
Diagnosis
Differential diagnosis
Clinical manifestations should be differentiated from esophagitis, peptic ulcer, various causes of dyspepsia, biliary tract disease, and esophageal motility.
