Esophageal hiatal hernia can cause chest pain. An esophageal hiatal hernia is caused by an abnormal development of the esophageal hiatus, which results in a series of symptoms or discomfort when abdominal organs or tissues such as the stomach, greater omentum, and intestines enter the chest through the esophageal hiatus in the presence of increased intra-abdominal pressure. Most of the symptoms of esophageal hiatal hernia are mainly acid reflux, heartburn, hiccups, retrosternal or epigastric pain, difficulty in swallowing, while some may have chest tightness, dyspnea and other discomforts, which can be easily misdiagnosed or missed, and need to undergo peptic imaging, gastroscopy and so on. Asymptomatic hiatal hernia patients usually do not need treatment, and symptomatic patients are treated with general treatment, medication and surgery. It is recommended that patients with hiatal hernia go to the Department of Thoracic Surgery as soon as possible and receive standardized treatment under the guidance of a physician.
