NON - ANATOMICAL
RESECTION
What is Non- Anatomical Resection?
Non-anatomical liver resection, often referred to as a wedge resection, is a surgical procedure where a diseased portion of the liver is removed without following the natural anatomical boundaries of liver segments. Unlike anatomical resections, which remove an entire lobe or segment, this technique focuses only on removing the tumor or affected area while preserving as much healthy liver tissue as possible.
When is it needed?
Non-anatomical resection is advised in select cases where organ preservation is more beneficial than extensive removal:
- Small Liver Tumors- When tumors are well-defined and away from major blood vessels.
- Benign Liver Lesions- Such as adenomas, hemangiomas, or focal nodular hyperplasia.
- Patients with Limited Liver Reserve- Especially those with cirrhosis or chronic liver disease.
- Metastatic Tumors- When cancer has spread to the liver but involves small, respectable deposits.
- High Risk Patients- Where larger resections could endanger overall liver function.
Process of Non- Anatomical Resection
Thorough imaging studies and liver function assessments to ensure surgery is safe.
Only the affected portion of the liver is carefully excised, leaving maximum healthy tissue intact.
Minimally invasive or open methods may be used depending on tumor location.
Close monitoring, pain management, and guided recovery to ensure a smooth return to normal life.
WHAT ARE
BENEFITS OF Non- Anatomical Resection
Choosing this conservative approach offers several important advantages:
Maximizes Liver Preservation
By removing only the diseased tissue and leaving the surrounding healthy liver untouched, this surgery ensures that patients retain maximum liver function for long-term safety.
Reduced surgical
risk
Since the resection volume is smaller compared to anatomical hepatectomies, the risks of bleeding, bile leakage, and other complications are significantly minimized.
safe for compromised livers
For patients with cirrhosis or reduced liver reserve, this technique offers a safer alternative by sparing as much functional tissue as possible.
faster recovery
Patients usually experience shorter hospital stays and a quicker return to daily activities, as the surgery is less extensive and less taxing on the body.
effective tumor control
When tumors are localized and well-defined, this surgery allows for complete removal with clear margins, offering excellent disease control without unnecessary tissue loss.
Flexibility of approach
Non-anatomical resections can be performed using open, laparoscopic, or robotic techniques, making it adaptable to different tumor locations and patient needs.
Why Trust Us for Non- Anatomical Resection

Our surgeons are trusted across India for their leadership in liver surgery. Their work has been featured in medical journals, presented at national conferences, and acknowledged in health magazines such as Silicon India (Top 10 Liver Transplant Surgeons, 2025).
FAQ
Common Questions We Hear From Patients
Your concerns are valid. Here are expert answers to help you make confident decisions about your liver health.
Yes, it is safe when performed on carefully selected patients. It is especially useful when complete liver removal is not possible due to limited reserve.
Anatomical resections remove whole liver segments based on vascular supply, while non-anatomical resections remove only the diseased portion without following natural segment boundaries.
Most patients recover within 5–7 days, though this may vary based on overall health and liver condition.
Yes, in many cases laparoscopic or robotic techniques are used for precise removal with minimal invasion.
No, the liver has a remarkable ability to regenerate. Since only a small portion is removed, function usually remains well-preserved.
Patients with large, multiple tumors or those involving critical vascular structures may not be suitable and may require major resections instead.
Take the First step to a
Precise surgery, safer recovery
Non-anatomical liver resection provides a safe, conservative option for patients who need tumor removal but cannot afford to lose large volumes of healthy liver. By choosing expert surgical care, you not only get precise tumor removal but also maximum preservation of liver function.
