Hepatectomy: The Definitive Guide to Liver Resection in the UK
Hepatectomy, or liver resection, is a complex surgical procedure that involves removing a portion of the liver. Despite its technical challenges, it has become an established treatment option for various liver conditions, including cancer and certain benign diseases. This comprehensive guide explains what Hepatectomy is, why it is performed, how specialists plan and carry out the operation, what patients can expect before and after surgery, and what the future holds for liver resections in the United Kingdom.
What Is Hepatectomy?
Definition and purpose
Hepatectomy refers to the surgical removal of part of the liver. The liver, the body’s largest internal organ, has a remarkable ability to regenerate after tissue loss. In a Hepatectomy, surgeons carefully remove diseased or damaged segments while preserving as much healthy liver tissue as possible. The overarching aim is to achieve local disease control while maintaining sufficient liver function for recovery and ongoing health.
Why some patients need a Hepatectomy
There are several circumstances in which a Hepatectomy may be recommended. These include malignant conditions such as hepatocellular carcinoma (primary liver cancer) and liver metastases from cancers located elsewhere in the body, most commonly colorectal cancer. Benign conditions—such as certain liver cysts or adenomas that threaten complications—may also be treated with removal of affected liver tissue. The decision hinges on tumour biology, liver reserve, overall health, and the feasibility of removing the disease while leaving enough healthy liver behind to support function.
Why and When Hepatectomy Is Considered
Indications: when a liver resection is appropriate
For hepatocellular carcinoma, Hepatectomy can offer potential cure or long-term disease control in carefully selected patients. When liver metastases are present, removing tumours can improve survival and, in some scenarios, enable other treatments such as chemotherapy or regional therapies. Benign lesions that cause symptoms or carry a risk of rupture may also prompt consideration of a Hepatectomy. The clinician weighs the extent of disease against the planned future liver remnant to ensure the liver will recover effectively after surgery.
Assessing the right candidate
Preoperative assessment focuses on liver function, volume, and the patient’s overall fitness. A patient’s age, coexisting medical conditions, and the presence of cirrhosis or hepatitis influence risk. Meticulous planning helps identify whether a standard or extended hepatectomy is feasible and whether additional procedures to boost liver capacity before surgery might be required.
Types of Hepatectomy
Anatomical vs non-anatomical (wedge) resection
Anatomical Hepatectomy follows the liver’s internal segmental anatomy, removing the entire segment(s) supplied by a specific hepatic artery and portal vein branch. Non-anatomical or wedge resections remove only the tumour and a small margin of surrounding tissue without strictly following segmental boundaries. Each approach has its place, depending on tumour size, location, and how much healthy liver can be spared.
Major vs minor hepatectomy
A minor Hepatectomy typically involves removal of a single segment or small portion of the liver. A major Hepatectomy refers to removing two or more segments or a larger portion, which carries greater risk of postoperative complications and a longer recovery but may be necessary to achieve clear margins.
Common resection types
- Right Hepatectomy (removal of segments V–VIII)
- Left Hepatectomy (removal of segments II–IV)
- Extended right or extended left hepatectomy (involving additional adjacent segments)
- Trisectionectomy or bi-segmentectomy in more extensive disease
- Segmentectomy (removal of a single liver segment)
Laparoscopic and robotic approaches
Hepatectomy can be performed through open surgery or using minimally invasive techniques such as laparoscopy or robotics. Laparoscopic Hepatectomy often results in smaller wounds, less pain, and faster recovery for suitable cases. Robotic-assisted techniques offer enhanced precision and range of motion for complex resections in experienced hands. Your surgical team will discuss the most appropriate approach based on tumour location, liver function, and their expertise.
Preoperative Assessment and Planning
Core tests and evaluations
Before a Hepatectomy, a thorough evaluation is carried out. Blood tests assess liver function, coagulation, and overall health. Imaging studies—typically contrast-enhanced CT or MRI scans—map tumour location and liver anatomy. An assessment of the future liver remnant (FLR) estimates how much healthy liver will remain after surgery, which is crucial for predicting postoperative liver function.
Liver function and risk stratification
Clinicians may use scoring systems such as the Child-Pugh score or the MELD score to gauge liver reserve. Tests like indocyanine green (ICG) clearance help measure how efficiently the liver processes substances and can inform surgical planning. In some cases, portal vein embolisation (PVE) or two-stage hepatectomy may be considered to stimulate growth of the remaining liver before the operation, increasing safety for larger resections.
Volumetry and future planning
Volumetric analysis estimates the volume of liver that will remain after the planned Hepatectomy. If the FLR is deemed insufficient, strategies to augment liver volume or alternative treatments may be explored. Comprehensive planning also includes assessing abdominal anatomy, prior surgeries, and potential adhesions that could influence access and technique during the operation.
The Surgical Journey: What Happens in the Operating Theatre
Anesthesia and patient preparation
Hepatectomy is performed under general anaesthesia. The anaesthetist monitors heart rhythm, blood pressure, oxygenation, and fluid balance throughout the procedure. A rolling or supine position is chosen to optimise access to the liver and control blood loss. Prophylactic antibiotics are commonly administered to reduce infection risk.
Approach and exposure
Surgeons select open, laparoscopic, or robotic techniques based on tumour location and the patient’s anatomy. The liver is carefully mobilised, and special attention is given to controlling bleeding, which can be significant in liver surgery given the organ’s abundant blood supply.
Bleeding control and liver transection
Strategies include the Pringle manoeuvre (temporary clamping of the hepatic inflow) to minimise blood loss during transection. Intraoperative ultrasound helps identify tumour margins and actual liver vessels. Parenchymal transection is performed with energy devices, ultrasonic shears, or advanced bipolar devices. Meticulous hemostasis is essential, and drains may be placed to monitor for postoperative fluid collections or leaks.
Specimen handling and recovery in theatre
The removed tissue is examined to confirm margins and characteristics. After resection, the liver is repositioned, and the wound is closed with care to reduce postoperative pain. Recovery in the operating theatre area precedes transfer to a dedicated postoperative ward or intensive care unit, depending on the patient’s condition and the extent of surgery.
Recovery and Aftercare
Immediate postoperative period
After a Hepatectomy, most patients spend time in a high-dependency or surgical ward. Pain control is tailored to maximise comfort while encouraging early movement and breathing exercises. Oxygen therapy and careful fluid management help support recovery. Nutrition is resumed gradually, with clear guidance on when to start eating and what to eat to aid healing.
Pain management and mobilisation
Effective pain relief typically includes a combination of regional anaesthesia, non-opioid analgesics, and, when appropriate, limited opioids. Early mobilisation reduces the risk of complications such as chest infections and deep vein thrombosis. Physiotherapists may support breathing exercises and gentle activity in the days following surgery.
Diet and activity after a Hepatectomy
Most patients can progress from intravenous to oral fluids and then to a regular diet as tolerated. Long-term activity is encouraged progressively, with a focus on gradually resuming normal daily life while avoiding heavy lifting in the initial weeks. The exact timeline varies by individual and the extent of resection.
Follow-up and surveillance
Postoperative follow-up typically includes clinical reviews, imaging, and blood tests to monitor liver function and check for recurrence. Adjuvant therapies, if indicated, are coordinated with the multidisciplinary team. Patients are advised on signs of potential complications and when to seek urgent care.
Risks and Complications
What to expect in the early days and weeks
All major surgeries carry risks. In Hepatectomy, potential complications include bile leak, infection, bleeding, and liver failure in rare cases. Other issues such as fluid collections, wound problems, or blood clots can occur. The team discusses these risks openly, helping patients make informed decisions about treatment options.
Long-term considerations
Most people recover well and regain normal activities, but some may experience slower liver function improvement or fatigue in the months following surgery. Regular follow-up helps detect any late complications and provides reassurance about recovery progress.
Recovery Timeline and Prognosis
Short-term milestones
In the first week after Hepatectomy, patients are closely monitored for signs of complications. By the second week, some may begin light activity and short walks. Hospital length of stay varies with the operation’s extent, but many patients are discharged within one to two weeks if recovery is uncomplicated.
Long-term outlook by indication
Outcomes after Hepatectomy depend on the underlying disease. For certain liver cancers and metastases, surgical resection can achieve long-term disease control and improved survival. The liver’s regenerative capacity supports recovery, especially in patients with good baseline liver function and careful perioperative management. The decision about proceeding with Hepatectomy includes a realistic appraisal of potential benefits and risks.
Living with Hepatectomy: Lifestyle and Aftercare
Dietary considerations
A balanced, liver-friendly diet supports healing. Emphasise vegetables, lean proteins, whole grains, and healthy fats while limiting highly processed foods, alcohol, and added sugars in the early postoperative period. Hydration and portion control help maintain energy as you adjust to new routines after Hepatectomy.
Activity and exercise
Gradual progression from gentle walking to more structured exercise is typical. Always follow your surgical team’s guidance regarding activity limits in the weeks following the operation. Returning to work and other daily activities should align with personal recovery and the advice given by clinicians.
Alcohol and medications
Your alcohol intake should be discussed with your doctor. In the healing phase, it’s common to limit or avoid alcohol to protect the liver. Always review medications with your healthcare team, especially over-the-counter remedies and supplements that could affect liver function or interact with prescribed therapies.
Vaccinations and health maintenance
Maintaining general health and following vaccination schedules, where appropriate, can help support recovery and reduce infection risk. Your clinician will provide tailored recommendations based on your health status and the nature of your liver condition.
The Future of Hepatectomy: Innovation and Research
Advances in imaging and planning
Improvements in preoperative imaging, volumetric analysis, and simulation help surgeons plan complex Hepatectomy with greater precision. Enhanced intraoperative imaging and navigation support better identification of tumour margins and important vessels, contributing to safer resections and better outcomes.
Minimally invasive and robotic techniques
Robotic and advanced laparoscopic approaches continue to expand the range of patients who can undergo Hepatectomy with less morbidity. As experience grows, more complex liver tumours can be addressed using these techniques, potentially shortening recovery times.
Strategies to protect the liver
Research into augmenting future liver remnant (FLR) and liver regeneration, including staged hepatectomies and ALPPS (Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy), aims to extend the boundaries of what is surgically feasible for patients with extensive liver disease. Such strategies are selected carefully, with patient safety as the priority.
Patient Experience in the UK: Pathways to Hepatectomy
Seeking a second opinion and multi-disciplinary care
Hepatectomy decisions are best made within a multidisciplinary team that includes hepatobiliary surgeons, radiologists, anaesthetists, hepatologists, and oncologists. If you have concerns or want to explore all options, seeking a second opinion can be valuable, particularly for complex cases.
Referral pathways and NHS versus private care
In the UK, referrals typically begin with a general practitioner or consultant who can direct you to specialised hepatobiliary services. NHS care offers comprehensive management and access to multidisciplinary teams, with private options available for those who prefer shorter wait times or additional choices. Your care team will discuss the most appropriate path based on clinical need and personal circumstances.
