Laparoscopic Cholecystectomy
The need to have one’s gallbladder removed is generally due to
the formation of gallstones. Gallstones form when there is an imbalance
in the components in the bile that is normally stored in the
gallbladder. For most people, there is no known reason why gallstones
develop. Nevertheless, there are diseases that can predispose your child
to form gallstones. Children who have problems with blood cells being
broken down easily such as can happen in spherocytosis and sickle cell
anemia have increased incidence of gallstone formation.
Gallstones can be asymptomatic in that they are present but cause no
symptoms. Gallstones can intermittently block the connection between the
gallbladder and the common bile duct which can cause pain.
Patients may have nausea and vomiting associated with this blockage.
The pain is generally in the upper abdomen and can be localized to the
right upper abdomen. These symptoms often resolve within a relatively
short time, but usually mean that the gallbladder should be removed.
Acute and chronic inflammation of the gallbladder can occur if there
is persistent obstruction of the connection between the gallbladder and
the common bile duct. This is called cholecystitis. This blockage of
bile flow can lead to inflammation and potential infection of the
gallbladder. The symptoms are similar to that of symptomatic gallstones
with the addition of fever and the persistent pain. Occasionally, the
gallstone can lodge in the bile duct connecting the liver to the
intestine and block all bile flow resulting in jaundice (yellowing of
the skin).
The easiest way to diagnose gallstones is by performing an ultrasound
test. Occasionally, gallstones can be seen on plain x-ray and CT scans.
Once gallstones are found, they rarely resolve spontaneously. In
general, if the patient has pain due to the gallstones, the best
treatment is surgical removal of the gallbladder.
Surgery for removal of the gallbladder is accomplished under general
anesthesia. Most patients can be admitted the morning of surgery.
Occasionally, your child may need to be admitted a day or two before
surgery for preoperative preparation. This can be necessary in children
with sickle cell anemia who need to be transfused and given fluids
before surgery.
The minimally invasive technique for removal of the gallbladder is
called laparoscopic cholecystectomy. This means that several small
incisions (1/4 – 1/2 inch) are used to place a telescope and other
small instruments into the abdomen. This is done instead of a large
incision in the right upper abdomen which was traditionally done prior
to the development of laparoscopic techniques. The advantages of the
laparoscopic technique are a shorter hospitalization, diminished pain,
better cosmetic result and earlier return to full physical activity.
Rarely, the gallbladder anatomy is such that the procedure needs to be
converted to an open operation. This happens when the surgeon does not
feel it is safe to do the operation with laparoscopy. This can happen
when the gallbladder anatomy is not routine, when there are bleeding
problems, or when there is so much inflammation in the gallbladder that
it is hard to identify the correct anatomy.
During the operation, the surgeon may or may not perform an
intraoperative cholangiogram. For this study, a catheter is placed in
the gallbladder and dye is injected into the common bile duct to ensure
that there is no other obstruction. If there is an obstruction to the
common bile duct, then the surgeon may elect to explore the bile duct
either with the laparoscopic equipment or with an open operation.
Another option would be to leave the stones for a gastroenterologist to
remove using an endoscope passed through the mouth and into the first
part of the small intestine. With the endoscope in the small intestine,
the opening of the common bile duct into the intestine is opened widely
to allow extraction of the gallstones.
Complications from the laparoscopic cholecystectomy are infrequent.
They include infection, bleeding, injury to the intestine and bile
duct.
Your child generally will be discharged home on the first day after
surgery. Most children can return to school within a week after surgery
and are ready for all physical activities within two weeks.
