Surgery for Living Liver Donors

What is surgery for living liver donors?

During surgery for living liver donation, surgeons remove part of a donor’s liver to transplant it into another person whose liver is no longer working (called a partial hepatectomy). Usually, a living liver donor must be age 18 or older.

Surgeons leave the rest of the donor’s liver in their body. This part will grow to at least 80% of its original size within a few months and will return to working normally. 

Type of surgery

What it does

Type of recipient

Right lobe hepatectomy

Removes 50-70% of the liver’s right lobe


Left lobe hepatectomy

Removes 20-50% of the liver’s left lobe

Adults who are small or not very sick, bigger children, and teens

Left lateral segment hepatectomy

Removes 10-25% of the liver’s left lobe

Small children

How does the donor transplant team know which part of the liver to remove?

To decide which part of your liver to remove, the donor transplant team will do imaging tests, such as an MRI or CT scan. These tests show the liver’s size and how your arteries, veins, and bile ducts are arranged in your body.

To decide how much liver the recipient needs, the recipient's transplant team will do similar tests and consider the recipient’s age, size, and how sick they are. 

What happens during the donor surgery?

For this major surgery, the donor transplant team will:

1. Give anesthesia to put you to sleep

2. Make a cut (incision) in your abdominal wall (belly area)

3. Remove the part of your liver that will best help the recipient – making sure you are left with enough liver (at least 30%) to support you until it grows bigger (regenerates) within a few months 

What will the recovery from donor surgery be like?

In the first week

Recovery from major surgery can be different for different donors, but usually:

  • You will stay in the hospital for 4-7 days
  • Your transplant team will check you very carefully for the first few days and do blood tests to make sure your liver returns to working normally
  • In the hospital, you will take strong pain medicine and the doctors will tell you how to return to normal eating and activity over time
  • You can go home once your pain, eating, and activity are stable

Don’t be alarmed if it seems that the recipient is having a faster and smoother recovery than you are as the donor. Remember that the recipient was sick before the transplant and now hopefully is doing better with a new liver, while you were healthy and then had a major surgery.   

In the first 3-4 months

In the first 3 months after donation, many donors have some physical symptoms such as belly or back pain. These go away over time in 3 months - 2 years after donation.

Your return to work after donation can depend on your symptoms, age, and how physical your job is:

  • Donors with jobs that take little physical work can usually return 1-2 months after surgery
  • Donors with jobs that take heavy lifting or other physical work may return 3 months or more after surgery to avoid problems
  • Rarely, donors aren’t able to return to their jobs because of physical symptoms

If you take care of family members such as children or your liver recipient, other people will need to take on those caregiving tasks while you recover.  

What are the possible problems from liver donor surgery?

Chance of problems

For liver donors, the chance of health problems from surgery is highest in the first 1-2 months after surgery. Once your remaining liver has grown back, your chance of problems is lowered.

Your chance of problems usually depends on how much of your liver is removed and if you have other health conditions:

  • Right lobe liver donors have health problems about 24-40% of the time (and severe problems happen more often in right lobe donors)
  • Left lobe liver donors have health problems about 9% of the time 

Common problems

This table shows problems from liver donation surgery and how often they happen. 

Less common problems

In people who donated their right lobe, recent reports show the risk of dying is 0.2% (2 in 1,000 people) or less.

According to OPTN/UNOS data as of September 15, 2020, out of 5,330 living liver donors in the US, 3 (0.06%) developed “liver failure/liver failure requiring a liver transplant”.

Given that the first adult-to-adult living donor liver transplant using the right lobe of the liver occurred in 1996, there are no outcome studies in right lobe donors beyond 20 years.
