There are 2 general types of surgical treatment for cancer of
the gallbladder -- potentially curative surgery and palliative surgery.
Potentially curative surgery is done when imaging tests
indicate a there is good chance that the surgeon will be able to remove
all of the cancer. Doctors may use the term resectable to
describe cancers they believe can be removed by potentially curative
surgery and unresectable
to describe those they think have spread too far or are in too
difficult a place to be entirely removed by surgery. Unfortunately,
only a small portion of gallbladder cancers are resectable when they
are first found.
Palliative surgery may be done to relieve pain or prevent
complications, such as blockage of the bile ducts, if the tumor is too
widespread to be completely removed. Palliative surgery is not expected
to cure the cancer, but it can sometimes help relieve symptoms and/or
prolong a person's life. Palliative surgery is described in more detail
in the section "Palliative
therapy."
Surgery to remove gallbladder cancer can have significant side
effects and, depending on how extensive it is, may require several
weeks for recovery. Patients whose cancer is not curable may want to
carefully weigh the pros and cons of surgery or treatments that require
significant recovery time. Unless there is clear evidence that such
treatments will improve the patient's chance for longer survival or
improved quality of life, some patients with very advanced stages of
gallbladder cancer may choose to avoid them.
Cholecystectomy (simple cholecystectomy)
The operation to remove the gallbladder is called a
cholecystectomy. If the entire gallbladder (but only the gallbladder)
is removed, the operation may be called simple cholecystectomy.
Most doctors use this operation to treat gallbladder cancer
only if there is a very good chance that the cancer is at a very early
stage (T1a) and is unlikely to have spread outside of the gallbladder.
It's not possible for doctors to know the true extent of the disease
until after surgery, when the gallbladder is looked at under a
microscope. If at this point the cancer is still found to be at an
early stage, no further surgery may be needed. But if the cancer is
found to be more advanced than was believed, a second, more extensive
surgery is typically recommended.
Gallbladder cancers are sometimes found incidentally (by
accident) after a person has a cholecystectomy for another reason, such
as gallstones. Again, if the doctor feels it's likely that the cancer
has been completely removed, no further surgery may be needed. If
there's a chance the cancer may have spread beyond the gallbladder,
more extensive surgery may be advised.
A simple cholecystectomy may be done in 2 ways:
Laparoscopic
cholecystectomy: This is the most common way to remove a
gallbladder for benign problems. This method uses a laparoscope, a
thin, flexible tube with a tiny video camera on the end that is
inserted through a small surgical opening in the patient's abdomen.
Surgical instruments are placed through several other small openings to
remove the gallbladder.
Laparoscopic surgery tends to be easier for patients because
of the smaller incision size. But because laparoscopic cholecystectomy
has sometimes led to the accidental spread of the cancer to other parts
the body, it is usually not done if gallbladder cancer is suspected.
If gallbladder cancer is found during a laparoscopic
cholecystectomy, the surgeon will switch to an open cholecystectomy
(making a larger incision and using standard surgery tools for the rest
of the operation). The change is made to avoid the risk of leaving
behind cancer that may have spread outside the gallbladder. It may also
avoid "seeding" the abdominal cavity with cancer cells that might be
squeezed out of the gallbladder as it is removed. Laparoscopic
cholecystectomy is not a cancer operation because most people treated
this way have cancer left behind that will need to be removed in
another, more extended, operation.
Open
cholecystectomy: In this approach, the surgeon removes
the gallbladder through a large incision (cut) in the abdominal wall.
This method is used for some operations for gallstones, and a type of
open cholecystectomy often is used if gallbladder cancer is suspected.
Extended (radical) cholecystectomy
Because of the risk that the cancer will come back if just the
gallbladder is removed, a more extensive operation, known as an
extended (or radical) cholecystectomy, is done in most cases of
gallbladder cancer. This can be an involved, complex operation, and it
is best done by a surgeon experienced in treating gallbladder cancer.
The extent of the surgery depends on where the cancer is
located and how far it might have spread. At a minimum, an extended
cholecystectomy removes:
- the gallbladder
- about an inch or more of liver tissue next to the
gallbladder
- all of the lymph nodes in the region
If the surgeon feels it is needed and the patient is healthy
enough, the operation may also include one or more of the following:
- removing more of the liver, ranging from a wedge-shaped
section of the liver close to the gallbladder (wedge resection) to a
whole lobe of the liver (hepatic lobectomy)
- removing the common bile duct
- removing part or all of the ligament that runs between the
liver and the intestines
- removing lymph nodes around the pancreas, around the major
blood vessels leading to the liver (the portal vein and hepatic
artery), and around the artery that brings blood to most of the small
intestine and to the pancreas (removing lymph nodes is called a lymphadenectomy or lymph node dissection)
- removing the duodenum (the first part of the small
intestine into which the bile duct drains)
- removing any other areas of organs to which cancer has
spread
Often, when gallbladder cancer is suspected, the surgeon will
do a laparoscopy before any other surgery. In this procedure, a small
cut is made so that a long, lighted tube called a laparoscope can be
inserted into the abdomen. The doctor uses the laparoscope to look
around the abdominal cavity for signs of cancer spread. This helps in
planning the operation to remove the cancer.
Possible risks and side effects
The risks and side effects of surgery depend in large part on
how much tissue is removed and a person's general health before the
surgery. All surgery carries some risk, including the possibility of
bleeding, infections, complications from anesthesia, and pneumonia.
Laparoscopic cholecystectomy is the least invasive operation
and tends to have fewer side effects. Most people will have at least
some pain from the incisions for a few days after the operation,
although this can usually be controlled with medicines if needed. The
incision is larger for an open cholecystectomy, so there is usually
more pain and a longer recovery time.
Extended cholecystectomy is a major operation that may involve
removing parts of several organs. This can have a significant effect on
a person's recovery and health after the surgery. Because most of the
organs are involved in digestion, eating problems may be a concern for
some time after surgery.
