Surgery for pancreatic cancer
Surgical treatment for pancreatic cancer falls into two main
categories. Firstly surgery can be performed to completely remove
the cancer, and secondly where surgery is necessary to help
alleviate symptoms.
Removing the cancer - Curative surgery
If the tumour is small (usually less than 3 cm across), there
are no signs that it has spread, and you are fit and healthy,
surgery is considered the most effective treatment option.
Unfortunately this usually only applies to about 15 to 20 out of
100 patients (15 - 20%).
This is considered a major operation and will only be done by a
specialist who is trained and experienced in pancreatic surgery.
You will probably need to be referred to a regional pancreatic
cancer surgical centre where the team get to treat between 100 -
200 pancreatic cancer patients a year. Click here to find out
where your nearest centre is.
Depending on where the cancer is and how much of the pancreas is
involved, potentially all or just part of the pancreas will be
removed:
- Whipple's operation - involves the removal of
the head of the pancreas, the lower end of the stomach, most of the
duodenum (first part of the small intestines), the common bile
duct, gall bladder and the surrounding lymph nodes. The remaining
part of the stomach, bile duct and pancreas are then reattached to
the small intestines.
- Pylorus-preserving pancreatoduodenectomy
- occasionally it is not necessary to remove the
lower end of the stomach thus preserving the stomach valve (the
pylorus) that empties into the small intestines.
- Distal pancreatectomy - also called 'left'
pancreatectomy, it is performed on the tail end or body of the
pancreas which is furthest away from the join to the duodenum
- Total pancreatectomy - sometimes it is
necessary to remove the whole pancreas if there is a large cystic
or endocrine tumour
Surgery for helping with symptoms of pancreatic cancer -
Palliative surgery
If the cancer has spread and cannot be removed, there are a
number of operations that might be recommended by your doctor to
help alleviate some of the symptoms of the disease. The most common
symptoms which need surgical intervention are jaundice, bowel
obstruction and pain.
Jaundice
This is caused when the cancer is blocking the bile duct and can
lead to a number of symptoms including:
- Yellowing of skin and eyes
- Feeling sick
- Itchy skin
- Altered bowel habits (wind and even pale smelly stools)
- Feeling weak and a general lack of energy
The blockage in the duct can be treated a number of ways:
- Insertion of a plastic or metal tube called a
stent - Usually this can be inserted endoscopically while
the patient is sedated. See the section on ERCP
- Endoscopic Retrograde Cholangio-Pancreatography in
the diagnosis section for more information.
- Biliary bypass - if placing a stent is not
possible, an operation that allows the bile to drain away by
bypassing the blockage can be performed. Also known as a
choledocho-jejunostomy it is where the bile duct is cut above the
blockage and then reattached directly into the small
intestines.
Bowel obstruction
The upper part of the small intestines - the duodenum - can
become blocked by the tumour. This will cause a number of symptoms
including:
- Feeling of sickness after eating
- Vomiting after eating which provides relief from the
symptoms
- Weight loss
This blockage is quite common and can be relieved by an
operation known as a:
- Gastric bypass - where the duodenum below the
blockage is attached directly to the stomach allowing the food to
pass through into the bowels.
Control of pain
If you have pain that is difficult to control with other
therapies (drugs or radiotherapy) it may be possible to treat
the pain by blocking the nerves that supply the pancreas.
- Coeliac plexus nerve block - the nerves from
the pancreas collect just behind it in a thick bundle called the
Coeliac Plexus. By injecting a special chemical directly into this
nerve plexus you may receive pain relief. The operation is usually
carried out under sedation in which you receive an injection in
your arm or the back of your hand that makes you drowsy and relaxed
but does not put you to 'sleep'. Then with the aid of a CT scan or
an EUS the doctor can inject the chemical into the nerve
plexus.
