Liver Transplant - Symptoms

liver transplant conditions & treatments

Unless the liver damage is fairly severe or advanced, diseases of the liver are often "silent", and patients may be unaware of any issues. Different liver diseases may affect some functions more than others, resulting in variability between patients.

Some symptoms include:

  • Yellow discoloration of skin and urine (Jaundice)          
  • Fluid buildup in the abdomen, legs and lungs
  • Easy bruising and bleeding, initially from the gums      
  • Increasing sensitivity with alcohol and drugs
  • Massive bleeding from the gut             
  • Serious infections
  • Drowsiness, forgetfulness, lack of concentration, confusion and coma

Types of Transplant


If your liver disease is progressive and liver transplantation may be the appropriate treatment, you will be referred to the liver transplant co-ordinator. Arrangements will be made for you to meet the liver specialist for an assessment. A variety of tests will be carried out to confirm the diagnosis, assess the extent of your disease and gauge your suitability for liver transplantation. The assessment period may take up to 5-7 days in hospital. 

There are 2 types of liver transplant available in Singapore, namely: Deceased Donor Liver Transplant and Living Donor Liver Transplant. 

1. Deceased Donor Liver Transplant (DDLT)

This involves replacing the recipient’s diseased liver with a whole liver from a deceased donor. A deceased donor is defined as a patient who is certified brain dead, however bodily function is maintained with medications and life support machines. This is beneficial to patients with decompensated liver disease like liver failure and liver cancer. With this transplant, it will help to prolong lifespan, improve quality of life and you will get to spend more time with your loved ones. However, deceased donors do not come by often and it happens rather spontaneously. The waiting time is therefore uncertain. 

2. Living Donor Liver Transplant (LDLT)

This involves replacing the recipient’s diseased liver with part of a healthy liver from a healthy living donor. This donor may be your immediate family or close friends. (benefits of surgery are the same as DDLT). Unlike DDLT, LDLT can be planned. It takes about 3 – 6 months from the start of counselling to the date of planned surgery. 

We would require another counselling session to go in detail regarding living donor living transplant. If any of your family members/ friends are keen to be a living donor, they could contact us anytime. 

Please know that LDLT does not affect your standing on the DDLT list. 

Waiting List

To select for patients to receive a deceased donor liver, we use a highly confidential list called the National Waiting List. This list is made up of patients grouped according to blood groups. 

Transplant Work Up 

Before we can put you on the DDLT national waiting list, we will need to determine if you are suitable to undergo a major surgery like liver transplant. Hence, you will be admitted for 5 – 7 days to undergo an extensive liver transplant work up.
 

What to expect while on the waiting list 

When you are officially listed on the DDLT national waiting list, it would mean that we may call you in at any point in time if there is a suitable donor for you. Your phone must be switched on 24/7, and you will need to update us if there are any changes to your contact details or any new phone numbers to be added. You will also have to update us if you are travelling. Waiting time for DDLT is unpredictable and may vary depending on your liver condition.  

In order to remain eligible on the waiting list, you will be asked to return regularly for blood tests, scans and appointments with our liver transplant specialist. Hence, you will have to come for your scheduled tests and appointments as arranged. We take patients’ compliance to appointments, tests and medications very seriously. 

Transplant Activation

When you are activated for liver transplant, you will have to make your way to SGH within the stipulated time given (1 to 1.5 hours) as DDLT is an emergency operation. You will be asked not to eat or drink anything from the time you receive our call. Blood tests, Xrays, ECG and COVID swab will be performed when you are admitted. You are only required to bring along your NRIC as well as a family member to assist with the administrative works for your admission. 

Please be expected to wait anytime between 6 to 12 hours from the time you are admitted till the commencement of your surgery as our team of specialists have to assess the condition of the donor’s liver. 


Liver Transplant - Preparing for surgery

Liver transplant is one of the most complicated surgeries one could undergo (hence requiring the extensive work up to ensure that your body is able to withstand a long surgery). For recipients, the total surgery time may range anywhere between 10 to 16 hours, sometimes even longer especially if you had past abdominal surgeries. This surgery involves making an incision across your mid abdomen in the shape of an inverted T. Your surgery proceeds in 2 major steps – the explantation of your diseased liver, followed by implantation of the donor’s liver.  

Liver Transplant - Post-surgery care

​Average length of stay is about 2 – 4 weeks depending on your recovery. SGH Liver Transplant team will work with you closely to help you towards your recovery, and you will be on lifetime follow up with us.

Frequently Asked Questions about Liver Transplant

What are the tests required for transplant suitability? 

During this work up, various blood tests, scans and x rays will be done to assess your heart, lungs and liver, as well as assessment by a team of transplant specialists. Since the tests and assessments are extensive, they will be done as inpatient over the course of 5 - 7 days. If more tests are required, you may need to stay even longer. 

After all the assessments are completed, our team will collate your reports and discussed in our Liver Transplant Meeting on the following Tuesday. Our team will discuss your tests results and determine if you are suitable to undergo liver transplant. We will contact you thereafter on your eligibility to be placed on the DDLT waiting list. 

What are the potential complications?

Surgical complications may include bile duct leakage, damage to the biliary tree, bleeding, formation of blood clots, infection (of wound or hospital acquired infections e.g. pneumonia), rejection of donated liver. Additional procedures/surgeries may be required if any of these complications arise. 

What to expect after a liver transplant surgery?

You will be admitted to the Surgical Intensive Care Unit (SICU) immediately after surgery where the team of specialists will monitor you very closely. Blood tests and scans will be done throughout the day to ensure there is no active bleeding/rejection/infections. There will be multiple tubes and lines (including feeding tube, indwelling urinary catheter (IUC), arterial lines, endotracheal tube) attached to your body, please do not be alarmed. The average length of stay in SICU stay is around 2 - 3 days and may defer depending on your rate of recovery. Once your condition improves, we will transfer you to a high dependency single room at our transplant ward where you will spend the rest of your stay recovering. Our transplant team will work with you closely to help you towards your recovery.

Please avoid carrying heavy objects for at least the first 6 months after surgery to allow your wound to completely heal. 

Will I be kept on any medications?

You will be given immunosuppressants to prevent your body from rejecting the new liver. 3 different agents will be given immediately post-transplant, namely:

  1. Tacrolimus (FK) or Cyclosporin
  2. Cellcept (MMF) or Myfortic
  3. Prednisolone (oral steroid)

Initial dosage of these medications will be high as the risks of rejection is the highest immediately after surgery. Your blood test results are indicative of how well your body is adapting to the new liver. Once your condition improves, our specialists will taper your medications down very carefully. Ideally, you will be left with only one type of immunosuppressant which you will have to take for life. 

Be expected to return for multiple appointments, scans and blood tests after surgery as it is crucial for us to monitor you closely to prevent any complications/rejections from occurring. Initially, you will have to return frequently for appointments with our liver transplant specialists. However, the frequency of appointments will decrease as your condition stabilizes over time. Most of our stable patients are only on annual follow up with us with 6 monthly interim blood tests and scans.

Liver transplant is a big step forward in your life where your compliance and dedication are tantamount.

What should I avoid after liver transplant?

  1. Alcohol: As alcohol is processed by the liver, it is essential to remain abstinent from alcohol after liver transplant.
  2. Smoking:  Cigarettes are the number one cause of death in Singapore through complications such as heart diseases and lung cancer. Cigarette smoking after a liver transplant may limit the extent of your recovery and return to fitness. You are not to resume smoking after liver transplant. By smoking, you are:
    • increasing your risk of chest infection
    • increasing your risk of lung cancer
    • increasing your risk of high blood pressure
    • Increasing your risk of having a heart attack or stroke
  3. Raw food: Risks of food contamination leading to infections
  4. Grapefruit: food-drug interactions with your immunosuppressants
  5. Sedentary lifestyle: Although your quality of life will improve after a liver transplant, you should continue to lead a healthy lifestyle.

When in doubt, always consult the liver transplant care team.
