- Liver resection involves removing a part of the liver – usually to treat a tumour or tumours.
- Liver resection relies on the fact that the liver is comprised of eight segments each with a separate blood supply and biliary drainage. Each segment or combination of segments can be removed safely up to 80% of normal liver volume (five to 6 segments in total). Ideally at least 20% of the liver volume should be left after surgery.
- If it looks like this figure may not be achieved after liver resection there are a number of interventions that can be undertaken to increase the size of the remaining liver.
The amount of liver that can be safely removed depends on how healthy the liver is.
- Liver resections are undertaken in three parts – dividing the blood supply to and biliary drainage as well as dividing the venous drainage from the liver to be removed. The final part involves dividing the liver tissue with an ultrasonic dissector (click here) which carefully divides the liver tissue and seals small blood vessels and bile ducts with heat.
- Liver resection can be undertaken via keyhole surgery (click here to see segments 2 and 3 removed using keyhole surgery) or using an open incision (click here to see the right side of the liver removed – segment 5-8)). In addition, at Harbour Surgery we also undertake keyhole surgery liver resections using the Da Vinci surgical robot to enhance the view and accuracy of the surgery.
The ability to perform the procedure laparoscopically or robotically depends on which part of the liver needs to be removed, the size of the tumour, the presence of adhesions from previous surgery and several other factors. The best approach for you will be discussed with you at your consultation.
Complications of liver surgery include:
- Bleeding
- Leak of bile from the cut liver surface
- Ascites (fluid development in the abdomen), jaundice, confusion and liver failure (where the remaining liver is not adequate)
- Overall the risk of dying during liver surgery is very low (<1/100,000). The risk of complications is dependent on the amount of liver removed and the type of operation. The most common complications are requiring a blood transfusion (risk 5%), a small bile leak from the cut edge of the liver (risk 7%: this is usually treated with aspiration under ultrasound guidance), chest infection (risk 5%; this is treated with antibiotics and physiotherapy) and blood clots (risk 1%; this is treated with blood thinning medication for several weeks).
