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.
