To
understand the nature of gallstones, it is helpful to first look at the
anatomy of the gallbladder and bile ducts. The gallbladder is a pear-shaped
organ that rests under the liver in the right upper abdomen. The liver
produces bile, a yellow liquid needed by the intestine to help digest
fat and oils. Ducts, or tubes, carry bile from the liver to the gallbladder
and on to the intestine. Bile is stored in the gallbladder, which contracts
periodically to force the bile into the intestine.
How Do Gallstones Form?
Bile is composed of a variety of chemicals, including cholesterol, salts,
and certain pigments. The gallbladder absorbs water from the bile, causing
it to thicken. In some people, tiny crystals form from the cholesterol
and pigments. These crystals gradually grow until one or even hundreds
of gallstones develop. About 80 percent of gallstones are composed of
cholesterol, while the remainder are made of pigments, salts, and other
chemicals.
Who
Develops Gallstones?
It is well known that in the Western world middle-aged, white females
are most likely to develop gallstones. However, by age 60, almost 30 percent
of all men and women have gallstones. Losing weight very rapidly produces
stones in some people. Asian and African people have a low incidence of
gallstones, while certain American Indian tribes have almost a 100 percent
incidence in females by middle age. Therefore, heredity, age, and diet
are probably all important factors in developing gallstones. Practically
anyone, at any age and under certain conditions, can develop these stones.
Symptoms
Many patients with gallstones never experience symptoms. However, as many
as one-half of all gallstone patients eventually experience one of the
following:
Colic -- Colicy pain usually occurs after meals when
the gallbladder contracts. During this process, gallstones can lodge in
the outlet neck of the gallbladder or even in the main bile duct to the
intestine. This situation causes intermittent, often severe pain, which
is experienced in the upper-middle or right side of the upper abdomen,
or even in the right shoulder and, sometimes, under the breast bone. Colic
attacks last from a few minutes to several hours.
Gallbladder Inflammation -- Occasionally, the stones irritate
the gallbladder to such an extent that active and acute inflammation
results. This condition produces steady, dull, and usually severe pain
in the upper-right abdomen. This is known as acute cholecystitis. It
is a serious condition.
Yellow Jaundice -- When a gallstone becomes permanently lodged
in the main bile duct, the bile flow is blocked and cannot reach the
intestine. Therefore, bile backs up in the liver and spills into the
blood. The skin turns yellow, the urine dark and, perhaps, the stool
white, since it is bile that colors the stool brown.
Other Symptoms -- Gallstones are frequently blamed for causing
indigestion, nausea, and intolerance to fatty foods. However, it has
been found that persons without gallstones experience these symptoms
as frequently as those with stones. Therefore, the physician cannot
be certain that gallstones are causing these symptoms.
Diagnosis
The physician, and even the patient, may suspect the presence of gallstones
simply from the medical history. An ultrasound or sonography exam provides
a simple, quick method of diagnosis. In this test, sound waves are beamed
into the gallbladder. This test looks at the anatomy of the gallbladder.
Another way of testing is to evaluate its function. In this test (a hepatobiliary
scan) a small amount of radioactive material is injected by vein (IV).
It then concentrates in the gallbladder. An agent is then given by IV
that will cause the gallbladder to contract and empty. A diseased gallbladder
does not do this very well and so this test can indicate a gallbladder
problem.
Treatment
Because many patients with gallstones never develop symptoms, watchful
waiting is often indicated. In fact, it is usually recommended that patients
without symptoms receive no treatment. When treatment is needed, it usually
involves one of the following:
Laparoscopic Surgery -- This technique has rapidly become
the treatment of choice for many gallstone patients. A tiny incision is
made through the navel. A microvideo tube is then inserted through it.
Three other needle-like instruments are then inserted through the upper
abdomen. These are used to pick up and dissect the gallbladder which,
together with the stones, is teased out of the small incision. With this
technique, patients can usually go home the same or next day.
General Surgery -- In the past, general surgery was the treatment
of choice for symptomatic gallstones. Laparoscopic surgery is now possible
in most patients. With general surgery there is a 3 to 6 inch incision
in the right upper abdomen and a 3 to 6 day hospital stay. There are
instances in which this type of surgery is still necessary.
Gallstone Dissolving -- Drugs are now available that dissolve
cholesterol gallstones. Complete dissolving of gallstones takes from
six months to two years, with maintenance treatment often required afterward.
This approach works best on small stones.
Because of the speed and simplicity of laparoscopic surgery, this technique
is by far the one most commonly used. The body can function quite well
without the gallbladder, although diarrhea can be an occasional problem,
especially in patients with irritable bowel syndrome.
Prevention
There is now enough known about gallstones that certain recommendations
can be made about how to prevent them in the first place. Some of this
knowledge is pretty firm while some is only suggestive at this time.
Hard Evidence -- Achieve and maintain ideal body weight
but do not lose more than 3 lbs per week, especially using the super low-calorie
liquid fasting diets.
Soft Evidence -- Increased fiber in the diet, vitamin C (no
more than 500 mg a day) and caffeinated coffee may all be helpful. Additionally,
regular recreational and physical activity - vigorous walking, gardening,
aerobics - seem to have protective value.
Summary
Gallstones are a common disorder and often cause no symptoms. However,
they can produce severe pain and serious problems which, when discovered,
require a well-developed plan of action. The goal should be to avoid emergency
complications and surgery. For symptomatic stones, laparoscopic surgery
is most commonly performed, although other forms of treatment are available.
By consulting with the physician, the right treatment choice can be made.
