Liver resection surgery is an operation to remove a diseased or damaged part of the liver while preserving enough healthy liver tissue to maintain essential functions.
I am Dr. Bipin Vibhute, Liver and Multiorgan Transplant Surgeon at Jupiter Hospital, Pune. I evaluate patients who may need liver surgery and help them understand when the procedure is appropriate, how it is performed, and what recovery involves.
The decision to perform liver resection depends on the underlying condition, the location and size of the affected area, the health of the remaining liver, and the patient’s overall fitness for surgery.
Key Takeaways
- Liver resection, also called hepatectomy, involves removing part of the liver or, in selected cases, a larger portion.
- It may be recommended for certain liver tumours, selected liver cancers, and specific non-cancerous liver conditions.
- The suitability of surgery depends on liver function, the amount of healthy liver remaining, and the patient’s overall health.
- Recovery varies according to the extent of surgery, the surgical approach, and any complications.
- The liver can regenerate after part of it is removed, provided the remaining liver tissue is healthy enough.
What Is Liver Resection Surgery?
Liver resection is a surgical procedure in which a portion of the liver containing a tumour, diseased tissue, or another abnormality is removed. The procedure is also known as a partial hepatectomy.
The liver performs several essential functions, including processing nutrients, producing bile, helping regulate blood clotting, and removing certain waste products from the blood. Because of these functions, planning liver surgery requires careful assessment of how much healthy liver tissue will remain after the operation.
The extent of resection depends on the location and spread of the disease. Some patients need only a small section removed, while others may require removal of a larger portion.
The aim is to remove the affected tissue while preserving enough functioning liver to support recovery and long-term health.
When Is Liver Resection Surgery Recommended?
Liver resection may be recommended when an abnormal area can be removed safely and the remaining liver is expected to function adequately.
The decision depends on the diagnosis and whether surgery offers a meaningful clinical benefit.
1. Liver Cancer
Some patients with primary liver cancer, including hepatocellular carcinoma, may be suitable for liver resection.
Suitability depends on the tumour’s size and location, whether it has spread, liver function, and the presence of conditions such as cirrhosis or portal hypertension. Not every patient with liver cancer can undergo resection.
Other treatments, including liver transplantation, may be more appropriate depending on the stage of the disease and the condition of the liver.
2. Liver Metastases
Cancer that begins in another organ can sometimes spread to the liver. In selected patients, particularly those with certain colorectal cancers that have spread to the liver, surgery to remove the affected tissue may form part of the treatment plan.
The decision depends on the primary cancer, the number and distribution of liver lesions, whether disease exists elsewhere, and whether all intended treatment targets can be addressed.
3. Benign Liver Tumours
Some non-cancerous liver growths do not require surgery and can be monitored. However, removal may be considered if a lesion causes symptoms, grows, has a significant risk of complications, or cannot be confidently distinguished from a malignant tumour.
The type of lesion and its clinical features guide the decision.
4. Selected Liver Cysts and Other Conditions
Certain complex cysts or other localised liver abnormalities may require surgery when they cause symptoms or complications. The appropriate treatment depends on the nature of the condition. Liver resection is not necessary for every liver cyst or benign abnormality.
Who Is Suitable for Liver Resection Surgery?
A patient may be suitable for liver resection if the disease can be removed effectively and enough healthy, functioning liver will remain after surgery.
For liver cancer, the National Cancer Institute’s PDQ treatment summary lists the criteria clinicians use to select patients for resection, including liver function and portal hypertension.
Before recommending an operation, I consider several factors:
- Liver function: The liver must have sufficient functional capacity to support the body after surgery.
- Location of the affected area: Its relationship to major blood vessels, bile ducts, and other structures influences the surgical plan.
- Extent of disease: The number, size, and distribution of lesions help determine whether removal is feasible.
- General health: Heart function, lung health, nutrition, and other medical conditions affect surgical risk.
- Underlying liver disease: Cirrhosis, fatty liver disease, or other chronic liver conditions may influence eligibility.
- Future liver remnant: The amount and quality of liver tissue expected to remain are central to surgical planning.
Some patients may benefit from other treatments before surgery or from a different treatment altogether.
For liver cancer, stage is a major part of that assessment, and Liver Cancer Stages: Your Treatment & Prognosis Guide explains how it shapes the options. The final recommendation follows a detailed assessment rather than the scan findings alone.
What Tests Are Needed Before Liver Resection?
Preoperative tests help identify the liver condition, map the affected area, assess liver function, and estimate whether surgery can be performed safely.
The exact tests depend on the patient’s diagnosis and medical history. They may include:
- Ultrasound, CT scan, or MRI: These help identify the location, size, and number of liver lesions and their relationship to important structures.
- Liver function tests: Blood tests assess aspects of liver health and function.
- Complete blood count and clotting tests: These help assess blood cell levels and the body’s ability to form clots.
- Kidney function and other blood tests: These help assess general fitness for surgery.
- Assessment of the future liver remnant: The surgical team evaluates how much functional liver tissue will remain after the planned resection.
- Additional investigations: Depending on the suspected diagnosis, further imaging, tumour markers, or other tests may be required.
A biopsy is not necessary in every case. Whether it is appropriate depends on the suspected condition and whether the result would change management.
How Is Liver Resection Surgery Performed?
Liver resection is performed under general anaesthesia, using an open or minimally invasive approach depending on the disease and the complexity of the operation.
For a side-by-side comparison of the two approaches, see Minimally Invasive vs Open HPB Surgery: What’s the Difference?
The surgical plan is individualised according to the location of the affected tissue and the amount of liver that needs to be removed.
- Open Liver Surgery
In open surgery, the surgeon makes an incision in the abdomen to access the liver. This approach may be needed for larger or more complex lesions, certain anatomical locations, or operations requiring extensive access to blood vessels and surrounding structures.
- Laparoscopic Liver Resection
In laparoscopic surgery, the surgeon uses specialised instruments and a camera inserted through small incisions. This approach may be suitable for selected patients and can offer benefits such as smaller incisions and potentially faster recovery.
However, laparoscopic surgery is not appropriate for every liver condition. The decision depends on the patient’s anatomy, the disease, and the surgical team’s assessment.
- Robotic-Assisted Liver Surgery
Robotic-assisted surgery may be an option in selected cases where the necessary equipment and expertise are available. It uses robotic instruments controlled by the surgeon.
The choice between open, laparoscopic, and robotic-assisted surgery depends on what is safest and most appropriate for the individual patient. Minimally invasive surgery is not automatically the best option in every case.
What Are the Risks of Liver Resection Surgery?
Liver resection is a major operation, and its risks depend on the extent of surgery, the patient’s liver function, and overall health.
Possible complications include:
- Bleeding: The liver has a rich blood supply, so bleeding can occur during or after surgery.
- Infection: An infection may develop in the wound or inside the abdomen.
- Bile leak: Bile may leak from the cut surface of the liver or a divided bile duct.
- Blood clots: Surgery and reduced mobility can increase the risk of clots.
- Liver dysfunction: The remaining liver may not function adequately, particularly if the preoperative liver reserve is poor.
- Fluid collections: Fluid may collect around the operated area and occasionally require treatment.
- Anaesthesia-related complications: These depend partly on the patient’s medical condition.
The risk of serious liver dysfunction is an important reason to assess liver function and the future liver remnant carefully before surgery.
I discuss the expected benefits, potential complications, and alternatives with patients before recommending the procedure. Individual risk cannot be determined from the diagnosis alone.
How Long Does It Take to Recover From Hepatectomy?
Recovery after hepatectomy varies according to the amount of liver removed, the surgical approach, the patient’s health, and whether complications occur.
Some patients recover sooner after minimally invasive surgery, while those undergoing extensive open surgery may need more time.
Recovery generally includes the following stages:
- First Few Days After Surgery
The medical team monitors pain, vital signs, liver function, bleeding, and other possible complications. Patients are usually encouraged to begin moving as soon as it is safe to do so.
Food and fluids are introduced according to recovery and medical advice.
- Hospital Recovery
The length of the hospital stay depends on the extent of surgery and the patient’s progress. Before discharge, the team assesses whether pain is controlled, eating and drinking are adequate, mobility is safe, and there are no complications requiring continued hospital care.
- First Few Weeks at Home
Tiredness, reduced appetite, and discomfort around the incision may continue for some time. Patients should gradually increase activity according to their surgeon’s instructions and avoid heavy lifting or strenuous exercise until cleared.
- Returning to Normal Activities
Some people resume lighter daily activities within a few weeks, while full recovery can take longer, particularly after extensive surgery. Return to work, driving, and exercise should be guided by recovery, medication use, and the surgeon’s advice.
There is no single liver resection recovery time that applies to every patient. Follow-up appointments help assess healing, liver function, and the need for any additional treatment.
Can the Liver Grow Back After Liver Resection?
Yes. The liver has a remarkable capacity to regenerate after part of it is removed, provided the remaining tissue is sufficiently healthy.
Regeneration means that the remaining liver tissue increases its mass and functional capacity to compensate for the removed portion. It does not mean that the liver necessarily grows back into exactly the same shape as before surgery.
The extent and speed of regeneration vary between patients. Factors such as underlying liver disease, the volume of liver removed, nutrition, and overall health can influence the process.
Patients with significant cirrhosis or impaired liver function may have a reduced capacity to recover. This is why assessing the quality and function of the remaining liver is as important as planning the removal of the diseased portion.
What Precautions Should You Take After Liver Resection?
Following your surgical team’s instructions and attending scheduled follow-up appointments are essential parts of recovery.
After discharge, patients should:
- Take prescribed medicines as directed.
- Keep the surgical wound clean and follow wound-care instructions.
- Eat balanced meals and maintain adequate fluid intake, as advised.
- Increase walking and other activities gradually.
- Avoid alcohol unless the treating team confirms it is safe. Patients with alcohol-related liver disease should receive specific advice and support.
- Avoid unapproved supplements or herbal products that may affect the liver or interact with medication.
- Attend follow-up visits and complete recommended blood tests or scans.
Seek urgent medical assessment if you develop fever, worsening abdominal pain, persistent vomiting, yellowing of the eyes or skin, increasing abdominal swelling, wound discharge, shortness of breath, or unusual bleeding. Sudden chest pain, severe breathing difficulty, or collapse requires emergency care.

Frequently Asked Questions About Liver Resection
1. Is liver resection a major surgery?
Yes, liver resection is generally considered major surgery. The extent of the operation and the patient’s overall health determine the level of risk and the recovery period. Smaller resections may be less complex than operations involving a larger portion of the liver.
2. Can you live normally after part of your liver is removed?
Many patients can return to their usual activities after recovery, provided the remaining liver functions adequately and the underlying condition is appropriately managed. Recovery and long-term outcomes depend on the amount removed, liver health, and whether further treatment is required.
3. What foods should I eat after liver resection surgery?
A balanced diet with adequate protein and calories can support healing. Depending on your condition, your team may recommend foods such as pulses, eggs, dairy products, fish, lean meats, vegetables, fruits, and whole grains. Dietary needs vary, especially in patients with chronic liver disease, so follow your clinician’s or dietitian’s advice.
4. How long will I stay in the hospital after hepatectomy?
The hospital stay depends on the extent of surgery and how quickly you recover. Your care team will monitor your condition and determine when it is safe to return home. Complications or additional medical needs may extend the stay.
5. When is liver resection necessary?
Liver resection may be necessary when a liver tumour or another localised condition can be removed safely and surgery offers a suitable treatment option. The decision depends on the diagnosis, disease extent, liver function, and the expected benefit of surgery.
6. Is liver resection possible for patients with cirrhosis?
Some patients with early or well-compensated cirrhosis may be considered for resection, but careful selection is essential. The degree of liver dysfunction, portal hypertension, and the amount of liver that would remain after surgery are important considerations. Other treatments may be more appropriate for some patients.
7. Can the liver grow back after liver resection?
The remaining liver can regenerate and increase its functional capacity after surgery. However, regeneration varies, and the liver may not return to its exact original shape or volume. Underlying liver disease can limit this process.
8. Is laparoscopic liver resection better than open surgery?
Neither approach is best for every patient. Laparoscopic surgery may offer smaller incisions and a potentially shorter recovery in selected cases. Open surgery may be more appropriate for complex or extensive procedures. The choice depends on the disease and the safest surgical plan.
9. What are the warning signs after liver resection surgery?
Fever, worsening abdominal pain, persistent vomiting, jaundice, increasing abdominal swelling, wound discharge, or unusual bleeding require prompt medical assessment. Severe breathing difficulty, chest pain, or collapse requires emergency care.
10. Does every liver tumour require surgery?
No. Not every liver tumour needs surgical removal. Management depends on whether the tumour is benign or malignant, its size and location, symptoms, disease stage, and the patient’s overall health. Options may include monitoring, surgery, local treatments, or other cancer therapies.
Final Thoughts
Liver resection can be an important treatment option for selected patients with liver tumours and other localised liver conditions. However, the decision requires more than identifying an abnormality on a scan.
The key is to determine whether the affected tissue can be removed safely while preserving enough healthy liver to support recovery. Careful preoperative assessment, an appropriate surgical approach, and structured postoperative follow-up all contribute to the treatment plan.
If you have been advised to consider hepatectomy, discuss the potential benefits, risks, alternatives, and expected recovery with a liver surgeon before making a decision.
