Microwave Ablation Burns Away Liver Tumors


CLEVELAND, Ohio. (Ivanhoe Newswire)— This year, over 40,000 people in the United States will be diagnosed with liver cancer. The gold standard for treating large malignant liver tumors is resection— cutting the tumor and the surrounding liver out of the body. Now, details on the first hospital in the world to perform a new microwave ablation technique that is burning away tennis ball-sized tumors.

For many patients with large liver tumors—the standard treatment is cutting it out, an option that can be traumatic and take a long time to recover. Now, Cleveland Clinic is the first hospital in the world to use newly FDA approved ablation technology that delivers 150-watts of microwave energy with a single needle.

Surgeons start this minimally invasive procedure by making two small incisions in the upper abdomen. Then …

“We insert this special camera, that we can look inside,” explained Eren Berber, MD, MBA, director of surgical liver tumor ablation at Cleveland Clinic.

This camera, and laparoscopic ultrasound, are used to examine the liver and expose the tumor for microwave ablation.

“Through a very small incision, a couple of millimeters, we introduce our ablation needle under the ultrasound guide,” described Dr. Berber.

Then, the microwave generator is fired up—delivering immense heat to Doctor Berber that he harnesses to burn and destroy the tumor.

Dr. Berber, a world leader in advanced laparoscopic ablation technologies, says that this treatment’s benefits include better recoveries, less pain, and a quicker return to normal life.

“If you burn it with these new technologies, the patients can go home the next day,” Dr. Berber shared.

Surgeons also perfom a biopsy during the procedure using a very small needle under the laparoscopic camera to confirm the diagnosis before proceeding with the microwave ablation. Following this groundbreaking procedure, the patient is doing well, and scans show no trace of the tumor.

TOPIC:            FIRST-IN-THE-WORLD MICROWAVE ABLATION BURNS AWAY LIVER                                    TUMORS

REPORT:       MB #4866

BACKGROUND: The liver is a vital organ that serves many critical functions in the body. It is responsible for metabolism of drugs and toxins, removing degradation products of normal body metabolism from the blood, and synthesis of many important proteins and enzymes. The liver is located in the upper right quadrant of the abdomen and is divided in eight segments reflecting the eight major divisions of the portal vein and bile duct. Blood enters the liver via two main channels, one being the hepatic artery and the other being the portal vein. These bring nutrients and oxygen into liver cells, also called hepatocytes, and bile ducts. Blood leaves the liver via hepatic veins and into the inferior vena cava which immediately enters the heart. The liver helps create bile, excretes it into microscopic channels that form into bile ducts that join into a single hepatic duct the brings bile to the intestine.

DIAGNOSING: The traditional form of treatment for large malignant tumors that form on the liver is resection, or hepatectomy. Liver resection is the removal of all or a portion of the liver. Only people with good liver function, good enough general health to sustain surgery, and a single tumor that has not grown into blood vessels can have this operation. Most patients with liver cancer also have cirrhosis meaning depending on the severity of the cirrhosis, there may not be enough liver left behind to properly function following resection. Before surgery becomes a viable treatment option, imaging tests such as CT and MRI with angiography are done to see if the cancer can actually be removed completely.

NEW TECHNOLOGY: Cleveland Clinic is the first hospital in the world to perform a new FDA-approved microwave ablation technology that can burn liver tumors away rather than cut them out. The procedure is minimally invasive and uses a single needle connected to a powerful 150-watt microwave generator. This new procedure can burn away a malignant liver tumor as large as two and a half inches. During the operation, a laparoscopic ultrasound probe is inserted through two small  incisions into the abdomen to locate the tumor. Surgeons then perform a quick biopsy using an extremely small biopsy needle under laparoscopic view to confirm the cancer diagnosis before proceeding with the ablation procedure. Then, using the ultrasound for navigation, a needle is inserted through the skin into the liver tumor. When surgeons are ready, the microwave generator is powered up, delivering heat that destroys the lesion. Ultrasound monitoring confirms the entirety of the tumor is treated by the microwave ablation.
