Liver Resections


Liver is the largest solid organ in the body. It occupies the right upper quadrant of the abdomen, tucked underneath the diaphragm. The liver has the major metabolic functions of the body all under control and it is vital and essential for life. The functions of the liver are:

  • a detoxifying function which is mainly getting rid of the toxic materials that get absorbed from the gastrointestinal tract and also the metabolites that are toxic to the bodies system that get produced by other organs, such as lactate and the false neurotransmitters. This detoxifying function is a major part of the liver function
  • regulation of blood glucose levels. A glucose homeostasis is an essential part for human life and the liver in addition to the pancreas play a major role in the process of metabolising and ensuring adequate levels of glucose in the blood for metabolic functions of the rest of the body.
  • production of the clotting factors that help the blood to coagulate whenever injury or a bleeding site occurs.
  • excretory function by which the liver gets rid of the bilirubin pigment which is the byproduct of recycling of red blood cells in the reticuloendothelial system of the body. This will be secreted by the liver in the form of what is called coagulated bilirubin. It is the pigment that gives the bile and the bowel motion its natural colour.

In terms of anatomy the liver is a solid organ supplied by a dual type of blood supply which is unique to the liver. A venous supply to the liver comes from what is called the portal vein and that is the vein that drains all the blood from the gastrointestinal tract from the stomach down to the rectum. So all the blood that comes from the gastrointestinal tract passes in the first instance into the liver for metabolic functions and detoxification and then it goes into the circulation by the inferior vena cava via what is called the hepatic veins. The liver also has got arteries that supply most of the oxygen to it and they come from the abdominal aorta.

Primary Liver Cancers

Primary Liver Cancer

Primary cancer of the liver is a common disease. It is a worldwide health problem, particularly in countries where there is a lot of infections with hepatitis virus B and hepatitis virus C. In Australia the main cause for the liver disease and cirrhosis is alcohol. There are other causes of cirrhosis, some of them are inherited, such as haemochromatosis and the disorders of metabolism of copper and there are other problems. Also with the rising incidence of obesity there is a disease which is called Nonalcoholic steatohepatitis (fatty liver).

If the disease is unchecked and untreated the process can progress into liver damage where the patient will manifest a disease which is called liver cirrhosis and in practical terms, what that means is they will likely to proceed to failure of the liver function which manifests itself in the form of bleeding tendency, yellow discolouration of the sclera of the eyes, weight loss and abdominal distention.

If the tumours of the liver are found early in the pace where they are in their early stages they can be cured by surgical treatment. That would be indicated for a low risk lesion particularly if it is less than 5cm. These lesions tend to be multiple where the liver could be effected in several areas as the process of cirrhosis makes the liver tissue a fertile ground for development of new growths.

You would need to discuss with your physician the available options of the treatment. The available options in general will be surgical resection which usually has the best outcome. That would be offered to a patient with good liver function when the disease is in its early stages. However, if the liver is badly diseased and reaching the final stages of liver cirrhosis then surgery won’t be an option. Some patients might be suitable for liver transplant in those cases.

There is an intermediate group where the cancer is advanced with bad features such as multi lobular disease and large size tumours and it may not be surgically treatable then a liver directed therapy in the form of localised chemotherapy of radiation therapy might be indicated.

Some patients do present at late stages where the liver function is quite poor and also their cancer is too bad. Patients in this situation might be advised only to have palliative measures or get enrolled in some medical trials if there are any available.

Liver Resection for Bowel Cancer

In the last two decades it has been established as an effective treatment for metastatic cancer of the bowel that spreads to the liver with a cure rate of almost 50%. When you discuss the cure rate with your surgeon this means that the patient who has had the operation will be well and alive in five years time after the operation. Usually the operation involves removal of one or more parts of the liver surgically. You find that commonly you would need chemotherapy, particularly if there are certain risk factors for recurrence. The recurrence rate is about 60% in the first few years. When the disease recurs there will be other forms of treatment. Surgery can still be done either as a second stage or a re-resection pattern. Also, there are other forms of liver directed therapy that can be useful. These might be internal chemotherapy or internal radiotherapy to the liver. The surgeon will discuss with you the pros and cons of having a liver resection for such type of tumours and you will need to be aware of the risks and complications that are associated with it and also the expected long-term benefits of the operation.

Liver Resection:



Segments of the human liver and current surgical nomenclature of liver sections.

Liver surgery  is proved to be safe and effective for a variety for condition such as primary tumours of then liver and secondary metastases, particularly metastatic bowel cancer, which is currently the most common indication for liver surgery.

Usually the patient gets admitted to the hospital on the morning of the operation, prior to that a thorough investigation is conducted to ensure that a patients general health, particularly the heart and lungs are suitable for major surgery.

A morphine injection in the spinal fluid is given for pain control. The operation is conducted under general anaesthesia, the anaesthetist will insert a venous access, arterial line for monitoring, administration of fluids and medications and a urine catheter is inserted when the patient is asleep.

Most operations are performed in an open fashion with incision below the right rib cage that is usually extended in the midline that will look like a Hocky stick.

The surgeon will perform ultrasound on the liver at the time of the exploration. The operation can take up to several hours depending on the complexity. Usually there is no need for a blood transfusion unless there is excessive loss due to complexity. At the end of the operation the patient will be awake and will spend a few nights in the intensive care unit for monitoring , the patient is allowed to resume oral intake on that evening. On average the patient will spend 5-7 days in the hospital


  1. Complications from any abdominal surgery is relatively common, such as respiratory and cardiac issues, also wound infections
  2. Bleeding: relatively uncommon, it manifests either as bleeding in the drain or falling levels of heamoglobin, this may necessitate blood transfusion or less likely a return to the operation theatre.
  3. Bile leak: this is specific to liver operations and is relatively common( 5-8%), bile leak can lead to internal infection and abscess collection; it is usually managed by endoscopy if bile appears in the drain, if an infective collection is suspected by fever and high white blood cells count, then a CT is performed and the collection gets drained in the radiology department.
  4. Liver failure: this is uncommon but a serious complication that can occur in complex situations and when the liver is diseased, it manifests as a rising level of bilirubin and deficiency of  clotting factors and excessive drowsiness. This occurs if the liver does not regenerate properly and usually becomes evident five days after the operation. There is no specific treatment to it apart from supportive care and  it can be fatal if there is no response.
