What is liver ablation?

liver ablation is surgical treatment of liver cancer. These treatments use a technique called radiofrequency ablation, in which a high -frequency electric current is used to destroy cancer cells. Radiofrequency ablation of the liver is a minimally invasive procedure that is an effective treatment option for many people with liver cancer, whether the tumor has been created in the liver or metastashed from another place.

Radiofrequency ablation of liver can be for many types of people. In particular, it is an effective alternative to surgical procedure and is therefore suitable for people who are not good surgical candidates. For example, if there are a few small tumors that must be removed if there is one or more tumors in a place that is not accessible by surgery, or if the patient is not good enough to undergo surgery, radiofrequency ablation may be a good alternative option.

This treatment of cancer relies on the use of radiofrequency equipment and medical equipmentDisplay. The medical imaging device used can be several types, including magnetic resonance imaging, computer tomography or ultrasound, depending on the patient's needs. This device is used during the procedure to guide the electrodes to the tumor.

Radiofrequency equipment used during the liver ablation procedure is able to generate high -frequency electric current. This electric current generates heat. Heat is able to destroy cancer cells when directed to a patient's tumor. This treatment destroys large amounts of healthy liver tissue because healthy cells have higher heat resistance than cancer cells. Treatment of ablation may therefore destroy cancer cells when leaving healthy tissue intact and unharmed.

Along with the destruction of cancer cells, radiofrequency energy, it also cauterizes and closes small bloods that feed the tumor. This significantly reduces the risk of cancer deathThe cells can cause bleeding in the liver. Over time, dead cancer cells are removed from the liver and are replaced by scar tissue.

In most cases, liver ablation may be performed under a local anesthetic. In this type of ablation, electrodes walk through small cuts in the skin. When this technique is used, the patient has intravenous sedative to help him stay relaxed all the time. Depending on the size and number of destroyed tumors, it takes a progress between one and three hours.

is normal to feel pain after radiofrequency ablation; This pain can usually be controlled by drugs for oral pain. For most people, pain is gone within one week. Approximately one week after the procedure, the patient will undergo a computer tomography scan (CT) or magnetic display (MRI) to determine how successful ablation of topacing was. Further scanning is done three to four times a year to determine whether new tumors have appeared.
