Congestive erosion of the lower esophagus near the cardia can be treated by identifying the cause of the disease, which usually includes general treatment, medication and surgery. Congestion and erosion of the lower esophagus near the cardia can be caused by improper diet, or gastroesophageal reflux disease, cardia cancer and other diseases. 1. Improper diet: prolonged intake of spicy and stimulating foods, raw and cold foods and prolonged alcohol abuse will damage the mucous membrane at the esophageal cardia, resulting in ulceration and erosion. You can maintain a light diet, avoid spicy and stimulating foods, and eat regularly to reduce the burden on the gastrointestinal tract. 2. Gastroesophageal reflux disease (GERD): gastroesophageal reflux patients’ gastric acid, bile and other digestive fluids go upward to stimulate the mucous membrane at the esophageal cardia, causing cardia erosion, you can use bismuth such as bismuth potassium citrate to protect the gastric mucous membrane; omeprazole and other proton pump inhibitors to inhibit the secretion of gastric acid; moxapride and other gastroenterological dynamics to promote gastric emptying to reduce the gastric reflux of gastric contents. 3. Cardia cancer: it is an epithelial malignant tumor occurring at the junction of stomach and esophagus, and erosion of cardia can be seen in gastroscopy, which is usually related to the tumor and stimulation of gastric acid. Endoscopic mucosal resection or endoscopic palliative treatment is feasible. It is recommended that patients with congestive erosion of the lower esophagus near the cardia consult a doctor to clarify the etiology, rationalize and standardize the treatment, and medications should be taken in accordance with the doctor’s instructions.
