Patients with recurrent years of untreated gastric disease are often diagnosed with chronic non-atrophic gastritis with bulging erosions or flat erosions after gastroscopy, and the symptoms are usually reduced with some gastric drugs such as omeprazole or traditional Chinese medicine, but the erosion foci are difficult to heal and eliminate, and the symptoms still recur, and once the diet is not careful, exertion or weather changes, the symptoms will be aggravated, repeatedly for many years, with multiple medical consultations and repeated gastroscopy, all suggesting the presence of Celiac foci, due to the lingering symptoms, seriously reduce the quality of life of patients. If left untreated for a long time, some patients can develop precancerous lesions such as intestinalization or atypical hyperplasia, and in severe cases, cancerous changes can occur. Why do these patients have various uncomfortable symptoms such as abdominal pain, distention and stuffiness that recur year after year? Whenever the stomach contraction, or slightly hard irritating food stimulation, or too much stomach acid, will stimulate the erosion foci, causing discomfort symptoms in the upper abdomen, such as distension, stuffiness, pain, etc., but the symptoms are not very serious, so some patients are negligent to consult the doctor and miss the treatment time, resulting in lifelong regret. Therefore, some patients are negligent in seeking medical treatment and miss the opportunity of treatment, resulting in lifelong regret. With the progress of modern science and technology, people have tried a variety of ways to treat these diseases, and in recent years our latest application of argon ion coagulation (commonly known as argon knife or APC surgery) has a very good clinical effect on these diseases. Argon ion coagulation, is a new non-contact treatment method, its energy through the ionization of argon gas conduction to the target tissue, so that the target tissue in the high temperature coagulation necrosis, so as to achieve the role of destruction of diseased tissue. Generally, the depth of coagulated target tissue does not exceed 0.3cm, which has the advantages of high efficiency, safety and small trauma. It is widely used clinically to stop bleeding in the gastrointestinal tract, palliative treatment of gastrointestinal tumors, and treatment of gastrointestinal polyps and gastric sinus capillary dilation, and many other diseases. This treatment method artificially destroys the erosion foci and regrows new mucosa, thus achieving the elimination of the erosion foci, and the patient’s abdominal pain and bloating symptoms are significantly improved, with excellent clinical efficacy.
