Typical symptoms of reflux esophagitis: heartburn, acid reflux, and sternal pain. This disease is commonly explained by the fact that food from the stomach or duodenum does not go down, but flows backwards into the stomach, esophagus, larynx and mouth, where the acidic substances such as stomach acid and bile burn the organ, causing acid reflux, heartburn and sternal pain due to pathological changes in the esophageal mucosa such as congestion and erosions and ulcers visible under the gastroscope. However, reflux esophagitis can also cause damage to tissues outside the esophagus, such as the pharynx and laryngeal airway, so it can sometimes be very “camouflaged”. It can manifest as other symptoms such as wheezing, coughing, foreign body sensation in the throat, belching, tightness in the throat, etc. It can be easily confused with other diseases such as non-cardiac chest pain, asthma, pharyngitis, throat reflux, ulcers, etc. Usually, mental stress, inattentive work and rest, irregular eating, obese people, smokers, and alcohol drinkers are the high-risk groups for GERD. In terms of age level, basically, middle-aged people around 40 years old have a higher percentage of GERD. GERD has become an increasingly prevalent disease worldwide, with a higher incidence of 10%-20% in Western countries. According to the statistics of the Chinese Society of Gastroenterology, the prevalence of GERD in China is gradually increasing. Treatment of GERD: In the past, the main treatment was gastroenterology, and patients needed long-term oral treatment with acid reflux inhibiting drugs, which had many side effects and gradually decreased in effectiveness. Due to the widespread use of laparoscopy, laparoscopic fundoplication for the treatment of reflux esophagitis and esophageal hiatal hernia has been clinically proven to be minimally invasive and reliable, and is currently the best surgical procedure for the treatment of reflux esophagitis and esophageal hiatal hernia, avoiding the drawbacks of long-term medication.
