What is a reasonable approach to the management of GERD?
There are several ways to approach the evaluation and
management of GERD. The approach depends primarily on
the frequency and severity of symptoms, the adequacy of
the response to treatment, and the presence of
complications.
For infrequent heartburn, the most common symptom of
GERD, life-style changes and an occasional antacid may
be all that is necessary. If heartburn is frequent,
daily non-prescription-strength (over-the-counter) H2
antagonists may be necessary. A foam barrier also can be
used with the antacid or H2 antagonist.
If life-style changes and antacids, non-prescription H2
antagonists, and a foam barrier do not adequately
relieve heartburn, it is time to see a physician for
further evaluation and to consider prescription-strength
drugs. The evaluation by the physician should include an
assessment for possible complications of GERD based on
the presence of such symptoms or findings as:
cough,
asthma,
hoarseness,
sore throat,
difficulty swallowing,
unexplained lung infections, or
anemia (due to bleeding from esophageal inflammation or
ulceration).
Clues to the presence of diseases that may mimic GERD,
such as gastric or duodenal ulcers and esophageal
motility disorders, should be sought.
If there are no symptoms or signs of complications and
no suspicion of other diseases, a therapeutic trial of
acid suppression with H2 antagonists often is used. If
H2 antagonists are not adequately effective, a second
trial, with the more potent PPIs, can be given.
Sometimes, a trial of treatment begins with a PPI and
skips the H2 antagonist. If treatment relieves the
symptoms completely, no further evaluation may be
necessary and the effective drug, the H2 antagonist or
PPI, is continued. As discussed previously, however,
there are potential problems with this commonly used
approach, and some physicians would recommend a further
evaluation for almost all patients they see.
If at the time of evaluation, there are symptoms or
signs that suggest complicated GERD or a disease other
than GERD or if the relief of symptoms with H2
antagonists or PPIs is not satisfactory, a further
evaluation by endoscopy (EGD) definitely should be done.
There are several possible results of endoscopy and each
requires a different approach to treatment. If the
esophagus is normal and no other diseases are found, the
goal of treatment simply is to relieve symptoms.
Therefore, prescription strength H2 antagonists or PPIs
are appropriate. If damage to the esophagus (esophagitis
or ulceration) is found, the goal of treatment is
healing the damage. In this case, PPIs are preferred
over H2 antagonists because they are more effective for
healing.
If complications of GERD, such as stricture or Barrett's
esophagus are found, treatment with PPIs also is more
appropriate. However, the adequacy of the PPI treatment
probably should be evaluated with a 24-hour pH study
during treatment with the PPI. (With PPIs, although the
amount of acid reflux may be reduced enough to control
symptoms, it may still be abnormally high. Therefore,
judging the adequacy of suppression of acid reflux by
only the response of symptoms to treatment is not
satisfactory.) Strictures may also need to be treated by
endoscopic dilatation (widening) of the esophageal
narrowing. With Barrett's esophagus, periodic endoscopic
examination should be done to identify pre-malignant
changes in the esophagus.
If symptoms of GERD do not respond to maximum doses of
PPI, there are two options for management. The first is
to perform 24-hour pH testing to determine whether the
PPI is ineffective or if a disease other than GERD is
likely to be present. If the PPI is ineffective, a
higher dose of PPI may be tried. The second option is to
go ahead without 24 hour pH testing and to increase the
dose of PPI. Another alternative is to add another drug
to the PPI that works in a way that is different from
the PPI, for example, a pro-motility drug or a foam
barrier. If necessary, all three types of drugs can be
used. If there is not a satisfactory response to this
maximal treatment, 24 hour pH testing should be done.
Who should consider surgery or, perhaps, an endoscopic
treatment trial for GERD? (As mentioned previously, the
effectiveness of the recently developed endoscopic
treatments remains to be determined.) Patients should
consider surgery if they have regurgitation that cannot
be controlled with drugs. This recommendation is
particularly important if the regurgitation results in
infections in the lungs or occurs at night when
aspiration into the lungs is more likely. Patients also
should consider surgery if they require large doses of
PPI or multiple drugs to control their reflux. Still, it
is debated whether or not a desire to be free of the
need to take life-long drugs to prevent symptoms of GERD
is by itself a satisfactory reason for having surgery.
Some physicians—primarily surgeons—recommend that all
patients with Barrett's esophagus should have surgery.
This recommendation is based on the belief that surgery
is more effective than treatment with drugs in
preventing both the reflux and the cancerous changes in
the esophagus. There are no studies, however,
demonstrating the superiority of surgery over drugs for
the treatment of GERD and its complications. Moreover,
the effectiveness of drug treatment can be monitored
with 24 hour pH testing. |
