What is reflux esophagitis? Reflux esophagitis is a disease in which stomach contents flow back into the esophagus causing clinical symptoms and inflammation of the esophagus. Patients usually present with heartburn, retrosternal pain, acid reflux and regurgitation, and difficulty swallowing. The symptoms are aggravated after eating and at night, and in severe cases, the patient cannot sleep flat, even with cough and reflux asthma, causing pain. What are the dangers of reflux esophagitis in Tianjin Nankai Hospital Minimally Invasive Surgery Center Zhao Hongzhi? Patients who do not undergo long-term systemic treatment or whose symptoms cannot be completely controlled by systemic medication will not only have narrowing of the esophagus, ulcers, or even complications of gastrointestinal bleeding, but can also progress to esophageal cancer in severe cases. What is the current status of treatment for reflux esophagitis? For moderate to severe reflux esophagitis, treatment by laparoscopic fundoplication has been internationally recognized as the gold standard for the treatment of the disease, with obvious advantages such as less trauma, shorter hospital stay, and good and long-lasting anti-reflux effect. In the past, PPI drugs (omeprazole, etc.) were usually taken for control, but long-term medication can cause serious side effects, such as anemia, and gradually have poor results. Our minimally invasive surgery center has carried out laparoscopic fundoplication to treat reflux esophagitis since 2001, which is the leading level in China. So far, our department has successfully performed hundreds of cases of this procedure, and the results of postoperative return visits are all good.
