Overview
Removing the left liver when disease sits on that side.
A total left hepatectomy removes segments 2, 3, and 4 of the liver — the entire left lobe — while the right liver (segments 5 through 8) is preserved. The left liver is the smaller side, accounting for roughly 30–40% of total volume, so this operation leaves more healthy liver behind than a right hepatectomy. It is the right operation when cancer or other disease is confined to the left side, and it is a critical part of treatment when hilar bile-duct cancer (Klatskin tumor) involves the left hepatic duct.
Left hepatectomies are particularly well suited to minimally invasive technique because the dissection is on the side of the abdomen that is easier to reach with a laparoscope or robot. When the disease involves the bile-duct confluence at the hilum, the operation is more complex — the liver remnant has to be reconnected to the intestine with a Roux-en-Y hepaticojejunostomy. We map the biliary anatomy on MRCP before surgery and plan the reconstruction step by step.
Who is a candidate?
Patients with disease confined to the left liver — primary liver cancer, intrahepatic bile-duct cancer, hilar cholangiocarcinoma involving left ducts, colorectal metastases, or selected benign tumors — are candidates. Because more healthy liver remains compared to a right hepatectomy, even patients with mild liver disease can often tolerate this operation safely. We confirm resectability with cross-sectional imaging, lab work, and tumor board review before proceeding.
How we perform it
You are asleep under general anesthesia. Through a small upper-abdominal incision or laparoscopic and robotic ports, we expose the porta hepatis and the left side of the liver. The left hepatic artery, left portal vein, and left hepatic duct are isolated and divided. The line of color change along Cantlie's line marks the transection plane. We divide the liver with ultrasonic dissection and energy sealing, controlling each small vessel and bile duct. The left hepatic vein is divided last. When hilar disease is involved, the right hepatic duct is reconstructed to a Roux limb of small bowel.
Recovery
Most patients stay 4–6 days in the hospital. The first day in step-down level care, then a regular room as recovery progresses. You will walk and start a regular diet within a day or two. Mild liver enzyme elevation is expected and resolves over weeks. We follow up at 2 weeks, repeat labs at 6 weeks, and image at 3 months — by which time the right liver has typically grown to nearly the size of the original whole liver and full normal activity is the rule.
Why Florida Surgical
Dr. Shaw is fellowship-trained in hepato-pancreato-biliary (HPB) surgery and surgical oncology. Hilar dissection, biliary reconstruction, and minimally invasive left hepatectomy are core expertise — and outcomes are tightly linked to the experience of the operating team. We use intraoperative ultrasound on every liver case and present every cancer at multidisciplinary tumor board so the surgical plan is paired with the right systemic therapy.
Frequently asked questions
How is this different from a right hepatectomy?
The left liver is smaller — segments 2, 3, and 4 make up about 30–40% of the total liver volume — so a total left hepatectomy is less of a volume hit than a right hepatectomy. It is the operation of choice when tumor sits on the left side or when the bile-duct cancer involves the left ducts.
Can this operation be done minimally invasively?
Left-sided liver resections — particularly the lateral segments (2 and 3) — are well suited to laparoscopic and robotic technique. A formal total left hepatectomy can be done minimally invasively in many cases when there is no major vascular involvement.
Will my liver grow back?
Yes. The right liver hypertrophies over weeks to months and takes over the work of the whole liver. Most patients have near-normal liver function by 3 months.
Why is the bile-duct anatomy important?
When the tumor is at the liver hilum — the entry point of the bile ducts and vessels — the left hepatic duct can be involved. We map the biliary anatomy before surgery and may need to reconstruct the bile drainage with a Roux-en-Y hepaticojejunostomy. This is high-specialty work and we plan it carefully.
What is the recovery like?
Most patients stay 4–6 days in the hospital — a little shorter than a right hepatectomy. Light activity at one to two weeks, return to most normal activities at 6 weeks, and full liver regrowth by 3 months.
