Reflux esophagitis is a relatively common benign gastroesophageal lesion, especially in young and middle-aged women. Symptoms can be mild or severe, mild reflux is only occasional acid reflux, heartburn sensation, quickly recover symptoms, without medication, severe patients, there will be significant acid reflux water, persistent burning sensation behind the sternum, and even pain in the throat, cough, very few will lead to asthma attacks, seriously affecting the quality of life, reflux esophagitis burning sensation behind the sternum. Diagnosis of reflux esophagitis: First, there are typical symptoms mentioned above, and second, it is clear through gastroscopy that inflammation and ulcerative manifestations of esophageal mucosa, or even intestinal epithelial metaplasia occurs in the lower esophageal mucosa (Barrett’s esophagus, a precancerous disease of esophageal cancer and esophagogastric junction cancer). If reflux esophagitis is clearly diagnosed, it needs to be treated according to the principles of reflux esophagitis treatment, and gastroscopy is an important tool for the diagnosis of reflux esophagitis. The pathogenesis of reflux esophagitis: It is the relaxation of the lower esophageal sphincter, the decrease of pressure in the esophagus, and the relaxation of the cardia, which leads to the reflux of gastric acid/pepsin and even bile into the esophagus. Normally, the mucosa of the esophagus is free from gastric juice and bile, and the corrosion of the esophageal mucosa by these digestive juices, and the destruction will lead to acute and chronic inflammatory episodes of the esophageal mucosa, and the digestive juices will also stimulate the throat, producing a burning sensation and irritation coughing and other symptoms. Treatment of reflux esophagitis: Improvement of dietary habits: In mild cases of reflux esophagitis, symptoms can usually be reduced by improving dietary habits. For example, reduce the amount of food eaten at each meal, eat small amounts of multiple meals, do not eat too full, and try to avoid foods that reduce the muscle tone of the lower esophagus, such as strong tea, chocolate, and high-fat foods. Obesity is also an unfavorable factor in reflux esophagitis, for obese patients should reduce weight can reduce intra-abdominal pressure and reflux. Reduce actions that increase abdominal pressure, such as avoiding weight holding and bending, do not wear tight clothing and pants, if you have long-term chronic constipation, it is recommended to take laxatives or drink more water to improve constipation. If combined with asthma, to consult the respiratory department, and actively treat asthma, is also possible to reduce abdominal pressure and reduce the chance of reflux. Elevating the head of the bed 15cm during sleep, not eating 6 hours before bedtime, and avoiding smoking and alcohol can all reduce the episodes of esophageal reflux, and minimize chocolate and strong tea. Medication: For patients with obvious symptoms, on the basis of improving diet and living habits, medication should be combined. Mainly from the following aspects of medication. 1, reduce gastric acid secretion: oral baking soda or aluminum hydroxide gel can neutralize gastric acid, reduce the acidity of gastric juice, and reduce the damage to esophageal mucosa; oral proton pump inhibitors, such as a variety of lazoloid drugs, are relatively strong drugs to inhibit gastric acid secretion. 2, drugs that promote the emptying of the esophagus and stomach: dopamine antagonists such drugs can promote the emptying of the esophagus and stomach and increase the tension of the LES. Such drugs include metoclopramide (gastrofluan) and domperidone (morpholine), taken before bed and before meals. Cisapride promotes peristalsis and emptying of the esophagus and stomach through the release of acetylcholine from the postganglionic nerves of the intestinal muscular plexus, thereby reducing gastroesophageal reflux, and oral medication to promote gastric motility. 3, the protection of the esophagus and gastric mucosa drugs: commonly used are colloidal bismuth pectin, magnesium aluminum carbonate, Jervil, etc. For patients whose symptoms are not relieved by improving their dietary habits and contents, and who are not relieved by regular medication, and whose lives are seriously affected by the treatment, consider surgery as appropriate. Surgical treatment: Generally, surgical treatment is not easily chosen. Unless the patient still has severe symptoms after regular medication and dietary improvement, or even causes chronic respiratory disease, surgery is considered to enhance the anti-reflux mechanism; or the patient has a severe esophageal hiatal hernia that requires surgical repair to alleviate the symptoms of esophageal reflux; or the long-term reflux leads to serious complications, such as severe stricture of the esophagus, and other problems that require surgical solution. Surgery is the last treatment option to be considered: For patients with clearly diagnosed reflux esophagitis, active treatment is recommended. Patients in remission after treatment will not cause serious consequences, but if there is no treatment or symptoms continue to worsen or persist for a long time, it may easily lead to the chemosis of squamous epithelial cells in the lower esophagus into intestinal epithelial cells (Barrett’s esophagus), which is prone to carcinogenesis. Active treatment of reflux esophagitis can effectively reduce the occurrence of esophageal cancer
