If a family member has just heard the words “you may need a liver transplant,” families are often reading late at night with several browser tabs open, trying to understand MELD scores, donor options, waiting lists, costs, risks, and hospital choices.
That is the most common starting point for almost every family who eventually walks into a transplant clinic.
This guide is written to help patients and families understand what a liver transplant actually involves, when it becomes necessary, how living and deceased donor pathways work in India, how the TRANSTAN process works in Tamil Nadu, what the surgery and recovery look like, and how to choose the surgeon and team they can trust with this decision.
The internet has thousands of pages on liver transplantation, but very few explain how this journey works for patients and families in Chennai and Tamil Nadu. This guide is meant to bridge that gap.
One thing Dr. Manikandan Kathirvel tells families early is this: not every patient with liver disease needs a transplant, and not every patient who needs a transplant needs it immediately. The purpose of a transplant evaluation is not to push every patient toward surgery. It is to understand whether transplantation is truly needed, whether the timing is right, and whether there are safer or better options available.
Key Takeaways
A liver transplant becomes necessary when the liver can no longer perform its essential functions, most commonly in decompensated cirrhosis, acute liver failure, or selected liver cancers confined to the liver.
India has two main transplant pathways: living donor liver transplant, where a healthy family member donates part of the liver, and deceased donor liver transplant, where an organ is allocated through a state waiting list.
The MELD score helps estimate how urgently a patient needs transplant. Most programmes begin considering deceased donor listing when the score approaches 15, but transplant timing depends on more than the number alone.
In Tamil Nadu, deceased donor liver allocation is managed by TRANSTAN, a state-run authority that prioritises patients based on medical urgency, blood group compatibility, and allocation rules.
A living donor transplant offers more control over timing, but donor safety must always be treated as seriously as recipient outcome.
Choosing a liver transplant surgeon should depend on transplant-specific experience, HPB expertise, hospital ICU infrastructure, donor safety protocols, transparency, and continuity of long-term care, not reputation alone.

What Is a Liver Transplant?
A liver transplant is a major operation in which a diseased or failing liver is removed and replaced with a healthy liver from a donor.
The donor liver may come from:
- A living donor, usually a close family member who donates part of their liver
- A deceased donor, usually a brain-dead donor whose liver is allocated through the state organ donation system
The liver is unique because it can regenerate. After living donation, both the donor’s remaining liver and the recipient’s transplanted liver segment grow over the following weeks to meet the body’s needs.
The liver performs hundreds of essential functions. It filters toxins, produces clotting proteins, supports digestion, regulates blood sugar, stores energy, and helps fight infection. When the liver fails completely, no machine can replace all these functions. Dialysis can temporarily support kidney failure, but there is no equivalent long-term machine for liver failure.
Once the liver has failed beyond recovery, transplantation becomes the only definitive treatment.
When Is a Liver Transplant Needed?
Not every patient with liver disease needs a transplant.
This is one of the most important points for families to understand.
Many patients have liver disease for years before transplant becomes necessary. The usual progression is:
- Fatty liver
- Liver inflammation
- Fibrosis
- Cirrhosis
- Decompensated cirrhosis or liver failure
A transplant is usually considered when the liver disease has reached the stage where complications begin to occur.
These include:
- Fluid accumulation in the abdomen, called ascites
- Vomiting blood or passing black stools due to variceal bleeding
- Confusion or drowsiness due to hepatic encephalopathy
- Persistent jaundice
- Repeated infections
- Kidney dysfunction due to liver failure
- Severe muscle wasting and frailty
- Certain liver cancers, especially hepatocellular carcinoma, when confined to the liver
In India, common causes of liver failure include:
- Alcohol-related liver disease
- Hepatitis B
- Hepatitis C
- Non-alcoholic fatty liver disease related to diabetes and obesity
- Autoimmune liver disease
- Metabolic and inherited liver conditions
- Acute liver failure due to viral hepatitis, drugs, or toxins
One of the commonest situations Dr. Manikandan Kathirvel sees is a family arriving after the first major emergency — vomiting blood, severe abdominal swelling, or ICU admission. In many of these patients, warning signs had been present for months. His advice is simple: do not wait for the next emergency before asking whether transplant should be considered.
Understanding the MELD Score
The MELD score, or Model for End-Stage Liver Disease score, is used to estimate the severity of liver disease and the urgency of transplant.
It is calculated using blood tests, mainly:
- Bilirubin
- Creatinine
- INR
The score usually ranges from 6 to 40.
| MELD Score | General Meaning |
| 6–14 | Liver disease present but relatively stable |
| 15–24 | Moderate to serious disease; transplant evaluation often begins |
| 25–34 | Severe liver disease; transplant becomes a clinical priority |
| 35–40 | Critical illness; urgent transplant may be needed |
A MELD score is very important, especially for deceased donor transplant waiting lists. However, it does not tell the whole story.
In his practice, Dr. Manikandan Kathirvel does not make transplant decisions based on MELD score alone. Some patients with modest MELD scores may have repeated infections, severe ascites, poor quality of life, muscle wasting, or repeated hospital admissions. These patients may be sicker than the number suggests. Equally, a patient with a high MELD score may sometimes improve with careful medical treatment.
The MELD score is a guide. It does not replace clinical judgement.
Signs That Suggest It Is Time for Transplant Evaluation
A patient with known liver disease should seek transplant evaluation if any of the following appear:
- Persistent jaundice
- Abdominal swelling
- Repeated fluid tapping
- Confusion, sleepiness, or personality change
- Vomiting blood
- Black stools
- Recurrent hospital admissions
- Kidney dysfunction
- Severe fatigue or muscle wasting
- Liver cancer diagnosed in a cirrhotic liver
None of these automatically means transplant is required. But they do mean the patient should be assessed by a liver transplant specialist.
Early evaluation gives families more options. Late evaluation often means decisions have to be made in crisis. [Request an Evaluation →]
Living Donor vs Deceased Donor Liver Transplant
Families in India usually face two possible pathways.
Living Donor Liver Transplant
In a living donor liver transplant, a healthy person donates part of their liver to the patient.
The donor is usually a close family member, such as:
- Spouse
- Parent
- Adult child
- Sibling
- Grandparent
Under Indian law, living liver donation is primarily allowed from near relatives. Donation from distant relatives or unrelated individuals requires additional approval from an Authorisation Committee to ensure the donation is voluntary and not commercial.
Living donor transplant is the dominant model in India because deceased organ donation has not yet met the national demand.
The advantage of living donor transplant is timing. The family does not need to wait for a deceased donor organ to become available. Once the recipient and donor are suitable, surgery can be planned.
However, donor safety is absolutely central.
Living liver donation is a major operation. It is not a minor procedure, and it is not risk-free. A responsible transplant programme treats the donor as a patient in their own right, not simply as a means to help the recipient.
A donor should be accepted only if the risk is medically acceptable.
For a complete picture of what donation involves, see What the Liver Donor Goes Through: Surgery, Recovery and Long-Term Health.
Deceased Donor Liver Transplant
In a deceased donor liver transplant, the liver comes from a brain-dead donor and is allocated through the state organ donation system.
This option is important for patients who:
- Do not have a suitable living donor
- Have donors who are medically unfit
- Prefer to avoid risk to a living donor
- Are already listed and waiting for an organ
The main challenge is timing. A deceased donor liver cannot be scheduled. It depends on organ availability, blood group, MELD score, and allocation priority.
In Tamil Nadu, this process is coordinated through TRANSTAN.
How TRANSTAN Works in Tamil Nadu
Tamil Nadu has one of India’s strongest deceased organ donation systems.
For liver transplant patients, this means the deceased donor pathway is organised through a formal state system rather than private negotiation.
In practical terms, the process involves:
- Evaluation by a transplant centre
The patient is assessed to confirm whether they are medically suitable for deceased donor liver transplant. - Registration with TRANSTAN
The hospital registers the patient on the deceased donor waiting list with the required documents. - Priority based on urgency and compatibility
Allocation is based on medical urgency, MELD score, blood group compatibility, and TRANSTAN rules. It is not simply first-come, first-served. - Organ availability
When a brain-dead donor becomes available, organs are matched according to the allocation policy. - Notification and surgery
If a suitable liver is allocated, the patient is called urgently for transplant.
A common misunderstanding is that families believe they should first try living donor transplant and only later register for deceased donor transplant if that fails. In many cases, that wastes valuable time.
Dr. Manikandan Kathirvel usually advises suitable patients to keep both options open: register for deceased donor transplant while simultaneously evaluating a living donor, if one is available. These pathways are not competitors. They are parallel options, and keeping both active often protects the patient from delay.
For a complete breakdown of the process and what to expect at each stage, see The TRANSTAN Process: How Deceased Donor Liver Transplants Work in Tamil Nadu.
How to Choose a Liver Transplant Surgeon
Choosing a liver transplant surgeon is one of the most important decisions a family will make.
This decision should not be based only on reputation, advertisements, or the size of the hospital building.
The following factors matter far more.
1. Transplant-specific experience
Liver transplant is not general surgery. It is not routine gastrointestinal surgery. It requires specific experience in complex liver anatomy, vascular reconstruction, graft selection, donor safety, and post-transplant complications.
Ask about the surgeon’s liver transplant experience specifically.
2. HPB expertise
Many transplant decisions overlap with complex liver, bile duct, and pancreas surgery.
A surgeon trained in both liver transplant and HPB surgery can guide patients more safely when the options include resection, transplant, biliary reconstruction, or non-surgical treatment.
3. Donor safety approach
For living donor transplant, the donor must be protected.
A good transplant surgeon should be willing to reject a donor if the risk is unacceptable, even if that delays the recipient’s surgery.
A donor is not just a donor. The donor is also a patient.
4. Hospital infrastructure
A liver transplant programme depends on the entire hospital ecosystem:
- Liver ICU
- Experienced transplant anaesthesia team
- Hepatology support
- Blood bank readiness
- Interventional radiology
- Infection control
- 24-hour transplant team availability
- Long-term follow-up system
The surgeon matters, but the system around the surgeon matters equally.
5. Transparency
A good surgeon should explain:
- Why transplant is needed
- Whether transplant can wait
- Whether alternatives exist
- What the risks are
- What can go wrong
- What recovery will involve
- What the long-term responsibilities are
Families should be cautious if they hear only reassurance and no discussion of risk.
6. Comfort with second opinions
A confident transplant surgeon should never be offended by a second opinion.
In fact, Dr. Manikandan Kathirvel encourages families to ask questions and compare opinions. A transplant decision should be made with clarity, not fear.
One question Dr. Manikandan Kathirvel believes every family should ask a transplant surgeon is:
“If this were your own family member, would you recommend transplant at this stage?”
The answer often reveals whether the recommendation is truly based on the patient’s condition and timing.
The Patient Journey: Evaluation, Surgery, and Recovery
Phase 1: Evaluation
A liver transplant evaluation usually includes:
- Liver function assessment
- MELD score calculation
- CT or MRI scan
- Cardiac assessment
- Lung assessment
- Infection screening
- Cancer screening where relevant
- Nutritional assessment
- Frailty assessment
- Psychosocial evaluation
- Anaesthesia fitness review
For living donor transplant, the donor undergoes a separate and equally detailed evaluation, including:
- Blood group compatibility
- Liver volume assessment
- CT angiography
- Bile duct anatomy assessment
- Medical fitness assessment
- Psychological and voluntary donation assessment
This phase may take a few days in urgent cases or a few weeks in stable cases.
Phase 2: Surgery
A living donor liver transplant involves two operations happening in coordination:
- Donor surgery to remove part of the liver
- Recipient surgery to remove the diseased liver and implant the donated liver portion
The surgery usually takes several hours and depends on anatomical complexity, recipient condition, and graft type.
A deceased donor liver transplant involves retrieval of the donor liver from another hospital or location, followed by implantation in the recipient.
Phase 3: ICU Recovery
After surgery, the patient is cared for in a dedicated liver transplant ICU.
The team monitors:
- Liver function
- Blood flow to the liver
- Bile production
- Kidney function
- Infection
- Bleeding
- Rejection
- Breathing and circulation
Most patients gradually move from ICU to the ward once stable.
Phase 4: Hospital Discharge
Hospital stay varies depending on the patient’s condition and recovery.
Many patients remain in hospital for two to three weeks, though some need longer if complications occur.
Before discharge, families are educated about:
- Immunosuppressant medicines
- Infection precautions
- Diet
- Blood test schedule
- Warning signs
- Follow-up visits
- When to contact the transplant team urgently
Phase 5: The First Year
The first year after liver transplant is the most important period of adjustment.
Patients need:
- Regular blood tests
- Medication monitoring
- Infection prevention
- Nutritional recovery
- Gradual return to activity
- Screening for rejection or complications
Immunosuppressant medicines must be taken lifelong unless changed by the transplant team. They should never be stopped because the patient feels well.
Most patients return to a good quality of life after transplant, but long-term success depends heavily on disciplined follow-up.
What the Liver Donor Goes Through
A living liver donor undergoes major surgery and deserves full, independent attention.
The donor evaluation checks:
- General health
- Liver size
- Liver fat content
- Blood vessels
- Bile ducts
- Future liver remnant
- Psychological readiness
- Voluntary consent
The donor operation removes a portion of the liver, usually the right or left lobe depending on recipient need and donor safety.
After donation:
- The donor usually spends time in ICU or high-dependency care
- Hospital stay is often shorter than the recipient’s
- Recovery at home takes several weeks
- Liver regeneration occurs over 6–8 weeks
- Most donors return to normal life after recovery
However, donation is not risk-free. Families should never be pressured into donation, and donors should never feel morally forced.
A safe transplant programme protects the donor even when the recipient is very sick.
HPB Conditions That May Lead to a Transplant Discussion
Some transplant discussions begin not with cirrhosis but with a complex HPB diagnosis.
This is where combined expertise in liver transplant and HPB surgery becomes especially important.
Hepatocellular Carcinoma
In patients with liver cancer arising in cirrhosis, the treatment may be:
- Liver resection
- Liver transplant
- Ablation
- TACE or other bridging treatment
- Systemic therapy
The right decision depends on tumour size, tumour number, liver function, portal hypertension, and transplant eligibility.
Hilar Cholangiocarcinoma
This is a complex bile duct cancer located where the right and left bile ducts join.
Treatment may involve:
- Major liver resection
- Bile duct resection
- Vascular reconstruction
- Selected transplant protocols in specific cases
These decisions require advanced liver and bile duct surgical judgement.
Severe Biliary Strictures
Complex bile duct strictures may occur after injury, inflammation, surgery, or chronic disease.
Some can be reconstructed surgically. Others may already have caused irreversible liver damage.
The key question is whether the patient needs reconstruction, resection, drainage, or transplant.
Complex Liver Tumours
Some liver tumours initially considered “inoperable” may still have options after specialist review, including:
- Portal vein embolisation
- Staged hepatectomy
- ALPPS in selected cases
- Vascular reconstruction
- Transplant in selected indications
- Downstaging treatment before surgery
A second opinion from a surgeon trained in both HPB and transplant surgery can be valuable before accepting that no surgical option exists.

Common Myths About Liver Transplant
Myth 1: “A liver transplant means the patient is at the end stage and nothing else can be done.”
Not always. Transplant is a major treatment, but in suitable patients it can restore long-term survival and quality of life.
Myth 2: “Older patients cannot undergo liver transplant.”
Age alone does not decide transplant eligibility. Overall fitness, heart and lung function, frailty, infection status, and cancer status matter more than age alone.
Myth 3: “A living donor will become weak forever.”
Most carefully selected donors recover well and return to normal life. However, donor surgery is still major surgery and must be approached seriously.
Myth 4: “The highest MELD score always means transplant immediately.”
A high MELD score indicates severity, but timing depends on the full clinical picture. Some patients improve with medical treatment, while others with lower MELD scores may need earlier transplant evaluation.
Myth 5: “Once transplant is done, medicines can eventually be stopped.”
Immunosuppressant medicines are lifelong. Stopping them without medical supervision can lead to rejection and graft loss.
Myth 6: “If one hospital says transplant is not possible, there is no hope.”
Not always. Complex cases should be reviewed by experienced liver transplant and HPB teams. In some cases, alternative surgical or non-surgical options may still exist.
About Dr. Manikandan Kathirvel
Dr. Manikandan Kathirvel is a Consultant Liver Transplant and HPB Surgeon at Gleneagles Hospital, Chennai, with over 15 years of surgical experience and more than 300 liver and pancreas transplants performed.
After completing his MBBS, MS in General Surgery, and M.Ch in Gastrointestinal Surgery at Amrita Institute of Medical Sciences, he undertook two consecutive advanced fellowships in the United Kingdom: an Advanced Multi-Organ Transplant Fellowship at Cambridge University Hospitals NHS Foundation Trust (2018–2020), followed by an Advanced HPB and Liver Transplant Fellowship at Royal Free London NHS Foundation Trust (2020–2023).
He subsequently held Consultant appointments across the Royal Free London NHS Foundation Trust and Whittington Health NHS Trust before returning to India.
He holds MRCS (England) from the Royal College of Surgeons of England, FRCS (Transplant Surgery) from the Royal College of Surgeons of Edinburgh—the UK subspecialty fellowship examination in transplant surgery—and MFSTEd (Membership of the Faculty of Surgical Trainers, Edinburgh), recognising his commitment to excellence in surgical education and training.
He has also been awarded CESR (Certificate of Eligibility for Specialist Registration) in General Surgery by the UK General Medical Council, confirming that his training and experience are equivalent to UK CCT (Certificate of Completion of Training) standards for independent consultant practice.
He has performed over 2,000 major HPB and gastrointestinal procedures across his career.

He has been an investigator and collaborator in several multicentre clinical studies and continues to contribute to research, quality improvement, and innovation within hepatobiliary and transplant surgery.
His dual training in transplant surgery and complex hepatobiliary and pancreatic surgery means he evaluates patients across the full spectrum of conditions covered in this guide, from straightforward living donor cases to the complex overlap between transplant decision-making and HPB oncology.
His approach is simple: not every patient needs surgery, and not every patient who needs surgery needs the same operation. His role is to help families understand the options clearly, explain risks honestly, and recommend the treatment that gives the best chance of meaningful long-term recovery.
Deciding What to Do Next?
If a family member has been diagnosed with decompensated cirrhosis, liver failure, liver cancer, or a complex HPB condition, it is better to seek clarity early. A transplant evaluation does not mean surgery is guaranteed. It means the patient’s condition, timing, risks, and options are properly assessed. Early assessment gives families time. Late assessment often leaves only emergency decisions. Request an evaluation with Dr. Manikandan Kathirvel in Chennai. No prior referral is required.
