Treatment of disorder
There is a muscle named as diaphragm between thoracic and abdominal. Organs continuing from thoracic to abdominal, such as Esophagus, main artery and inferior main artery, are coming through the diaphragm. The hole where thoracic is coming through diaphragm is called as esophageal hiatus.
The status where part of stomach in the abdominal breaks into thoracic through the esophageal hiatus, is called as esophageal hiatal hernia.
Esophageal hiatus become loose by advancing age or congenital reason, and by applying pressure from abdominal, esophageal hiatal hernia is developed. Report says that this disease is common among middle to high aged women.
The reason of abdominal pressure, chronic cough caused by obesity or bronchial asthma can be considered.
Even though there is esophageal hiatal hernia, in case if there are no symptoms, it does not become problem. But by having esophageal hiatal hernia if stomach acid backflows to esophagus, symptoms like heart burn or abnormal feeling at thoracic area may appear. These status is called as reflux esophagitis.
Diagnosed by upper alimentary canal contrast study or upper alimentary canal endoscopic exam. Depend on the shape of hernia, it is categorized into ;
Among above category, sliding type is common.
Oral medicine treatment is performed to prevent backflow of stomach acid as main symptom improvement. But when oral medicine treatment does not improve symptom, then surgical operation is performed.
Bring a broken stomach part back to abdominal, and make loosed and enlarged esophageal hiatus to small to prevent breakage. And, surgery, which binds stomach around esophagus to prevent backflow of stomach acid, is added. (Nissen method). Recently, laparoscopic surgery, which apply less burden to patient, is conducting.
Refraining from alcohol, caffeine or oily food may prevent backflow of stomach acid. Besides, backflow of stomach acid becomes easy to occur if lay down immediately after the meal.
