ABOUT HISTOTRIPSY TREATMENT
Histotripsy is a non-invasive, image-guided treatment that destroys liver tumors using focused ultrasound energy. It is delivered through the Edison System, which sends high-intensity sound waves into the body to create microscopic bubble clouds within targeted tissue. These bubbles mechanically break down tumor cells, without the need for incisions, needles, radiation, or heat.
Unlike thermal ablation techniques such as radiofrequency ablation or microwave ablation, histotripsy does not rely on heat or radiation. Instead, it works mechanically, at the cellular level, which helps preserve nearby healthy liver tissue.
Histotripsy may be recommended for liver tumors that are not suitable for surgical removal, particularly when a non-invasive, localized option is needed. It is typically performed by trained specialists under imaging guidance, alongside ongoing monitoring and, when appropriate, other liver-directed or systemic cancer therapies.
WHO HISTOTRIPSY MAY BE SUITABLE FOR
Eligibility for histotripsy depends on your tumor characteristics, overall liver function, and treatment goals. Your healthcare provider may recommend histotripsy if you have liver tumors that are not suitable for surgical removal, need a non-invasive treatment option, or are not a candidate for thermal ablation procedures.
Histotripsy may also be considered when localized tumor treatment is needed while preserving surrounding healthy liver tissue. Locoregional therapies like histotripsy are generally recommended based on the size, number, and location of liver tumors, as well as overall liver function.
Because every patient's tumor and liver condition is different, there is no one-size-fits-all answer to who should have histotripsy. Your healthcare provider determines whether ultrasound-based therapy is an appropriate option after a full assessment of your liver disease and treatment goals.
ELIGIBILITY OVERVIEW
Histotripsy may be considered for adults with the following conditions, needs, or treatment goals:
Before recommending histotripsy, healthcare providers evaluate several factors to determine whether it is an appropriate option, including:
HOW HISTOTRIPSY CAN HELP YOUR LIVER
Histotripsy uses focused ultrasound energy to target liver tumors from outside the body. The Edison System delivers high-intensity sound waves through the skin to the tumor site, creating microscopic bubble clouds within the targeted tissue.
These bubble clouds mechanically disrupt and destroy tumor cells, without relying on heat, radiation, or surgical incisions. Because the effect is mechanical and tightly focused, histotripsy can preserve nearby healthy liver tissue while treating the tumor.
Histotripsy is performed by trained specialists under imaging guidance. Depending on the treatment plan and patient needs, sedation or anesthesia may be used. Long-term management after treatment depends on how the tumor responds, the stage of disease, and whether additional liver-directed or systemic therapies are needed.
LIVER BENEFITS
Before treatment, imaging studies identify and map the tumor. The Edison System then delivers focused ultrasound pulses through the skin to the targeted liver lesion. Because the energy comes from outside the body, no surgical incision or needle placement is required.
Focused ultrasound pulses create microscopic bubble clouds within the targeted tissue. These bubbles mechanically disrupt and destroy tumor cells. The tumor is broken down by this mechanical action, not by heat or radiation.
Histotripsy avoids the use of heat, radiation, and surgical incisions. This makes it an option for people who need a non-invasive treatment or who are not candidates for thermal ablation procedures. Your healthcare provider decides whether ultrasound-based therapy is appropriate for you.
The treatment is aimed at the tumor, so it is designed to minimize damage to the healthy liver tissue around it. This matters for people who need localized tumor treatment while keeping as much surrounding liver tissue as possible.
Histotripsy works mechanically, using focused ultrasound, to destroy liver tumors while preserving healthy surrounding tissue. It should only be performed and monitored under the guidance of a qualified healthcare team.
TREATMENT PROCESS
Imaging studies, such as CT or MRI, are performed to identify and map the tumor before treatment.
The Edison System delivers focused ultrasound pulses through the skin to the targeted liver lesion. No surgical incision or needle placement is required.
Treatment is performed by trained specialists under imaging guidance. Sedation or anesthesia may be used depending on the treatment plan and patient needs.
Most patients experience a relatively short recovery period and may resume normal activities soon after treatment, as advised by their healthcare provider.
Histotripsy is typically performed in one or more treatment sessions. Long-term management depends on tumor response, disease stage, and whether additional liver-directed or systemic therapies are needed.
Follow-up imaging and clinical assessments are performed to evaluate treatment response and monitor for tumor recurrence.
BENEFITS AND SAFETY
Histotripsy may support people with liver tumors that are not suitable for surgery by destroying tumor cells mechanically, without incisions, needles, radiation, or heat. Because the treatment is tightly focused, it can help minimize damage to the surrounding healthy liver tissue, and its non-invasive approach may allow for a shorter recovery and outpatient potential. The extent of these benefits varies from person to person, depending on tumor size, location, and overall liver function.
Histotripsy is not a stand-alone treatment — it works best as part of a broader, personalized care plan that may include imaging-based monitoring and, when appropriate, other liver-directed or systemic cancer therapies.
As with any procedure, histotripsy may cause side effects, ranging from mild discomfort near the treatment area to temporary changes in liver enzyme levels. Your healthcare provider will monitor your treatment response and liver function through follow-up imaging and clinical assessments.
BENEFITS
Histotripsy requires no incisions or needles. The ultrasound pulses pass through the skin to reach the tumor, which offers a non-invasive way to treat liver tumors that are not suitable for surgical removal.
The focused ultrasound energy minimizes damage to the liver tissue around the treated tumor. Keeping surrounding tissue intact is important for people who need localized treatment.
Histotripsy uses ultrasound energy rather than radiation to destroy tumor cells. It also does not rely on heat. Instead, it creates microscopic bubbles that mechanically break down the tumor.
Because histotripsy is non-invasive, it may allow shorter recovery times. Most patients have a relatively short recovery and may resume normal activities soon after treatment, as advised by their healthcare provider. Your own recovery depends on your care plan.
These effects are often mild and temporary. Your healthcare provider will discuss the potential benefits and risks before treatment and provide ongoing support, including follow-up imaging, to monitor treatment response.
SUPPORTING YOUR RESULTS
After histotripsy, patients are advised to maintain routine liver health follow-up, avoid alcohol if liver disease is present, and stay hydrated.
Following your oncology care plan, which may include combination systemic or liver-directed therapies, can help support long-term outcomes alongside histotripsy.

COMMON QUESTIONS
Histotripsy destroys the liver tumors it targets, but it does not replace the rest of your care. It is a localized treatment that uses focused ultrasound energy to break down tumor cells. What happens over the long term depends on how your tumor responds, your disease stage, and whether you need additional liver-directed or systemic therapies. Follow-up imaging and clinical assessments check how well treatment worked and watch for tumor recurrence. Talk with your healthcare provider about realistic goals for your treatment plan.
Your healthcare provider decides this after a full assessment. Histotripsy may be recommended if you have liver tumors that are not suitable for surgical removal, need a non-invasive treatment option, or are not a candidate for thermal ablation procedures. It may also be considered when you need localized tumor treatment that preserves the surrounding liver tissue. Your provider looks at the size, number, and location of your tumors, your overall liver function, and your imaging before deciding whether ultrasound-based therapy is appropriate.
Histotripsy works mechanically, while thermal ablation uses heat. The Edison System delivers focused ultrasound pulses that create microscopic bubble clouds inside the targeted tissue. These bubbles break down tumor cells without heat, radiation, or surgical incisions. Because the energy is tightly focused, the treatment is designed to preserve nearby healthy liver tissue. Histotripsy may be an option for people who are not candidates for thermal ablation, such as radiofrequency or microwave ablation.
The treatment is done from outside the body, with no incision or needle. First, imaging studies identify and map your tumor. During the procedure, the Edison System sends focused ultrasound pulses through your skin to the targeted liver lesion. Trained specialists perform the treatment under imaging guidance. Depending on your treatment plan and needs, you may receive sedation or anesthesia. Your care team will explain what to expect before your appointment.
Most people have a relatively short recovery and may return to normal activities soon after treatment, as their healthcare provider advises. Because histotripsy is non-invasive, it may allow shorter recovery times than more invasive options. Your own timeline depends on your overall health, your treatment plan, and the extent of treatment. During recovery, your provider may advise you to keep up routine liver follow-up, avoid alcohol if you have liver disease, and stay hydrated.
The most common side effects are abdominal discomfort, fatigue, mild pain near the treatment area, and mild swelling or inflammation in the treated area. Some people also have a temporary rise in liver enzymes. These effects are often mild and temporary. Your healthcare provider will discuss the potential benefits and risks with you before treatment. They will also monitor your response and liver function with follow-up imaging and clinical assessments.
