What is liver resection and why is it done?
Liver resection in plain language
is a surgical removal of the entire or certain portion of the liver. It is also
known as partial or full hepatectomy depending upon the amount of the liver
portion removed. A complete liver resection is carried out in setting of a
transplant of a diseased liver and then it is removed from the deceased donor.
A living donor is needed to give the patient that amount of liver tissue which
is fixed with the procedure called partial hepatectomy. This procedure is
usually carried out with both minimally invasive or the traditional open
surgical approaches. The goal of the procedure called liver resection to make
the patient free from the tumor he or she has in the liver tissues.
Which patients with liver cancer undergo liver resection?
The patients suffering from liver
cancer (also known as Hepatocellular Cancer or HCC), the procedure liver
resection is confined to the patients with 1 or 2 small size tumors that is
confined inside the liver with no invasion seen over the blood vessels. This
simply result to the stringent rules, in practice, very limited amount of
patients with this ailment can undergo the surgery called liver resection. One
of the biggest concerns to this procedure regarding the resection is that after
the surgery, the patient may end getting the liver failure with this ailment.
The failure of the liver can occur when the remaining portion of this organ is
improper or linked with the menace called caner.
What is the goal of liver resection?
The goal of this procedure is to
simply get rid of the tumor seen in the liver tissues along with the
surrounding areas without leaving a single cell of the tumor. This procedure is
therefore limited to the patients who are seen with around few small size
tumors usually of 3 cm or less and the best liver function, ideally without
linked cirrhosis. This simply results to these ardent protocols hence very
limited amount of liver cancer that is seen going for this surgery. However,
the only one worry, which the patients can unfortunately face is the liver
failure after this surgery, which is regarded as one of the fatal risks of the
procedure.
Can a portion of the remaining normal liver grow back?
The answer is yes. When you find
your liver being removed with small amount of liver from your body, the
remaining ones can be easily seen growing back to the appropriate lost size in
order to see them in an original position. This regeneration can be seen
occurring within 1-2 weeks. However, the cirrhotic liver cannot be seen growing
back hence before the procedure resection is carried out for the ailment, the
non-tumor area of the liver, which has to be biopsied in order to find whether
these are linked to cirrhosis.
What are the results (survival and recurrence) of liver resection?
For the patients suffering from
HCC and have opted this procedure is seen having a five year survival seen
among the people of around 10 to 60 percent. This will depend upon the kind and
size of the tumor. A number of these patients are seen with recurrence of the
liver cancer, which can be seen in other portion of the organ of liver. Also,
it should be kept in mind that the survival rate of the patients not opting the
surgery with similar sort of tumor is possibly comparable. As per some studies
carried out in the west, the survival rate of people consuming alcohol
injection or radiofrequency ablation procedure can be compared to the survival
rates of the people who have opted for the resection surgery. But make sure these cannot be compared head
to head.
