Hiatus Hernia is a condition in which the upperpart of stomach bulges or squeezes through the opening in diaphragm (large muscle separating chest and abdomen). Diaphragm has a slight natural opening (hiatus) that acts as a path for oesophagus which allows the food to enter the stomach. However, when stomach gets pushed through diaphragm in the chest, hiatus hernia develops.
A small Hiatus Hernia has almost no signs and symptoms and may be discovered accidentally during other workup. However, large hital hernia may allow food & acid to go back in esophagus causing Heartburn.
Other symptoms which may be seen with large hernia are acid reflux or regurgitation of food or liquids in mouth, difficulty in swallowing, shortness of breath and occasionally chest pain.
Diagnosis is usually by upper GI Endoscopy done for one of the typical symptoms or seen accidentally while evaluating other disease. In this the endoscopist passes a flexible tube with camera and light (endoscope) down the throat and visualizes the inside of esophagus and stomach. Other tests are contrast x-ray of upper digestive system (Barium Meal) – wherein contrast coating allows the radiologist to identify silhouette of stomach protruding in the chest and esophageal manometry and 24hour pH study.
Since most people with hiatus hernia do not have any symptoms, they won’t need any treatment. However if the hernia is large and if one experience recurrent heartburn, acid reflux or breathing discomfort, treatment may be needed.
With the current minimally invasive approach, the morbidity of surgery is least and results excellent
