Hiatus Hernia
The
hiatus hernia is one of the most misunderstood and maligned conditions
in medicine. People blame this hernia for much more than it ever does.
Patients with a hiatus hernia need to understand what it is and what might
occur with it. Most importantly, they need to know it is unusual for serious
problems to develop from this type of hernia.
Anatomy
The diaphragm is a sheet of muscle that separates the lungs from the
abdomen. When a person takes a deep breath, the dome-shaped diaphragm
contracts and flattens. In doing this, the diaphragm pulls air into the
lungs. The left diaphragm contains a small hole through which passes the
tube-shaped esophagus that carries food and liquid to the stomach. Normally
this hole, called a hiatus, is small and fits snugly around the esophagus.
The J-shaped stomach sits below the diaphragm.
What Causes a Hiatus Hernia?
In some people, the hiatus or hole in the diaphragm weakens and enlarges.
It is not known why this occurs. It may be due to heredity, while in others
it may be caused by obesity, exercises such as weightlifting, or straining
at stool. Whatever the cause, a portion of the stomach herniates, or moves
up, into the chest cavity through this enlarged hole. A hiatus hernia
is now present. Hiatus hernias are very common, occuring in up to 60 percent
of people by age 60.
What Are the Different Types of Hiatus Hernia?
- Sliding Hiatus Hernia -- In this most common type of hiatus
hernia, the herniated portion of the stomach slides back and forth,
into and out of the chest. These hernias are normally small and usually
cause no problems or even symptoms.
- Fixed Hiatus Hernia -- In this case, the upper part of the
stomach is caught up in the chest. Even with this hernia, there may
be few symptoms. However, the potential for problems in the esophagus
is increased.
- Complicated or Serious Hiatus Hernia -- Fortunately, this type
of hernia is uncommon. It includes a variety of patterns of herniation
of the stomach, including cases in which the entire stomach moves up
in the chest. There is a high likelihood that medical problems will
occur with this hernia and that treatment, frequently involving surgery,
will be required. Complicated hernias are uncommon.
Symptoms
In most patients, hiatus hernias cause no symptoms. This is especially
true of sliding hernias. When symptoms occur, they may only be heartburn
and regurgitation, when stomach acid refluxes back into the esophagus.
Some patients with fixed hiatus hernias experience chronic reflux of acid
into the esophagus, which may cause injury and bleeding. Anemia, or low
red blood cell count, can result. Further, chronic inflammation of the
lower esophagus may produce scarring and narrowing in this area. This,
in turn, makes swallowing difficult, and food does not pass easily into
the stomach.
Does Hiatus Hernia Cause Pain and Indigestion?
It is wrong to always blame a hiatus hernia for pain and indigestion.
Hiatus hernias generally do not cause acute pain. This symptom may result
from other disorders, such as peptic ulcers or even heart disease. Some
patients with coronary heart disease fool themselves into believing their
discomfort is due to a hiatus hernia. If upper-abdominal pain or indigestion
occurs, people should not mislead themselves into thinking the cause is
a hiatus hernia. Instead, the patient should seek medical advice.
Diagnosis
Diagnosis of a hiatus hernia is typically made through an upper GI
barium x-ray. A complementary test is gastroscopy, or upper-intestinal
endoscopy, in which the physician visually examines the esophagus and
stomach using a flexible scope while the patient is lightly sedated.
What Are the Complications?
The complications of hiatus hernia are:
- Chronic heartburn and inflammation of the lower esophagus, called
reflux esophagitis
- Anemia due to chronic bleeding from the lower esophagus
- Scarring and narrowing of the lower esophagus causing difficulty in
swallowing
- While sleeping, stomach secretions can seep up the esophagus and into
the lungs causing chronic cough, wheezing, and even pneumonia
In addition, the complicated hernia can cause serious problems such as
difficulty in breathing or severe chest pain, especially in the elderly.
Treatment
Treatment is called for only when the hernia results in symptoms,
such as persistent heartburn or difficulty in swallowing. Acid inflammation
and ulceration of the lower esophagus also require treatment.
General guidelines for treating heartburn and esophagitis (inflammation
of the esophagus) are:
- Avoid (or use only in moderation) foods and substances that increase
reflux of acid into the esophagus, such as:
- nicotine (cigarettes)
- caffeine
- chocolate
- fatty foods
- peppermint
- alcohol
- spearmint
- Eat smaller, more frequent meals and do not eat within 2-3 hours of
bedtime.
- Avoid bending, stooping, abdominal exercises, tight belts, and girdles
all of which increase abdominal pressure and cause reflux.
- If overweight, lose weight. Obesity also increases abdominal pressure.
- Prescription medications. Certain drugs, such as intestinal antispasmodics,
calcium channel blockers, and some antidepressants weaken the muscle
strength of the lower espohagus.
- Elevate the head of the bed 8 to 10 inches by putting pillows or a
wedge under the upper part of the mattress. Gravity then helps keep
stomach acid out of the esophagus while sleeping.
Other Treatments
Drugs -- Some medicines effectively reduce the secretion
of stomach acid, while others increase the muscle strength of the lower
esophagus, thereby reducing acid reflux.
Surgery -- The complicated hiatus hernia requires surgery occasionally
on an emergency basis. Surgery otherwise is reserved for those patients
with complications that cannot be handled with medications. The mere
presence of a hiatus hernia is not a reason for surgery.
Summary
A hiatus hernia is an extremely common condition which usually does
not cause symptoms or problems. However, when it does, the physician can
frequently treat the problem effectively with a well-planned program.
Surgery is infrequently required to treat a hiatus hernia.
