CONTACT SPECIALISTWhat are oncological liver resections?
Liver resections consist of surgical removal of a portion of the liver containing a tumor. It is the treatment with the greatest curative potential for colorectal liver metastases and for primary liver tumors such as hepatocellular carcinoma.
The liver has a unique regeneration capacity, allowing removal of up to 70-80% of the organ in patients with preserved liver function. This property makes extensive resections with curative intent possible.
Types of liver resections
Different types of resection exist depending on tumor extent and location:
Segmentectomy
Resection of one or several liver segments following the vascular anatomy of the liver. Allows larger resections with less parenchymal loss.
Hepatectomy
Removal of a complete liver lobe (right or left). Necessary for large or central tumors.
Extended hepatectomy
Resection of more than 60% of the liver. May require preoperative preparation techniques to increase the volume of the liver remnant.
High-complexity techniques in liver surgery
We use the most modern techniques to optimize outcomes:
Laparoscopic and robotic surgery
Minimally invasive approach for selected resections, with less postoperative pain and faster recovery.
Portal vein embolization
Preoperative technique to induce hypertrophy of the liver lobe that will remain after resection, making initially unresectable cases operable.
ALPPS
Two-stage procedure that accelerates liver regeneration, allowing extensive resections in patients with insufficient liver volume.
Intraoperative ultrasound
Real-time visualization of vascular anatomy and liver lesions during surgery to guide resection.
Indications for liver surgery
Liver resections are indicated in various pathologies:
Colorectal metastases
Main indication for oncological liver surgery. Resection can be curative in selected patients with 5-year survival rates exceeding 50%.
Hepatocellular carcinoma
Primary liver tumor. Resection is indicated in patients with preserved liver function and localized disease.
Cholangiocarcinoma
Intrahepatic bile duct tumor. Requires extensive resections including the affected bile duct.
Metastases from other origins
In selected cases, metastases from neuroendocrine tumors, breast, ovary, or others may benefit from liver surgery.
Our experience in liver surgery
At Quenet-Torrent Institute we have a team specialized in oncological hepatobiliary surgery. We perform the full spectrum of liver resections, from minimally invasive procedures to complex hepatectomies.
We work in close collaboration with interventional radiologists, medical oncologists, and hepatologists to offer a multidisciplinary approach that maximizes treatment options for each patient.

Wonderful surgical team, among the best out there. Dr. Torrent (expert in peritoneal carcinomatosis) is an exceptional surgeon and an even better person. His coordinator is super kind, fast and efficient. The human treatment is great and the results are too. This is of vital importance for cancer patients.

In the public healthcare system they gave my father a maximum of one year to live. They only offered him chemo and no hope, said it was impossible, that nothing could be done. He had several tumors inside the peritoneal sac with metastases. A year and a half later he is clean, completely cured. His latest PET scan came back clean. We are very happy. Thanks to Dr. Torrent and his team. THANK YOU.

Excellent professionals, especially Dr. Torrent, attentive at all times to the patient (my wife), operated for peritoneal pseudomyxoma. They helped us with all our needs since we came from outside Barcelona. Thank you Elisabeth. We are very grateful to Quenet Torrent Institute, thank you for everything.

I am a 63-year-old patient. They detected adrenal gland cancer and told me there was nothing to be done. I sought a second opinion and they told me about the Quenet Torrent team, specialists in complex operations. Dr. Torrent, from the first moment, told me they could operate. They operated and removed a large tumor mass. I spent a week in the ICU and a month on the ward. Every day he came morning and evening, no matter Saturday or Sunday. Never throw in the towel. I am happy to have found these professionals who gave me my life back. Thank you.

I have peritoneal carcinomatosis. Sending my diagnosis to every center, practically all agreed on palliative chemo with little survival time since I had very aggressive cell types. Until we reached Dr. Quenet, Dr. Torrent and their team. I can only confirm what their CV announces: they are far ahead of the rest. They saved my life — at surgery the harmful cells everyone diagnosed (and used to refuse to operate) were not there. This intervention has become the best investment of my life.
