major trial to test a new surgical approach for lung cancer patients -

The University of the CHUM Research Centre (CRCHUM) is launching a major international clinical trial to test a minimally invasive surgical approach and safer for patients with lung cancer. thoracoscopy (VATS) lobectomy with ultrasonic sealing of the video-assisted pulmonary artery
Monic Ste-Marie, 48, is one of the first to benefit from this procedure developed by Dr. Moishe Liberman, thoracic surgeon and researcher at the CHUM Research Centre. January 19, 2016, he successfully removed the tumor of one centimeter lodged in his left lung. The operation was to make three small incisions in the chest and then removing the diseased part of the lung, guided by a video camera and using an electronic device to seal the pulmonary artery ultrasound to prevent bleeding during the operation.
"I think this technique could completely change the way we perform the surgery for lung cancer, which is the deadliest form of cancer in North America," said Dr. Liberman, who is also associate professor of surgery at the University of Montreal.
Currently, pulmonary lobectomy is the operation of a cancer of the lung most commonly performed in the world. It involves opening the chest and cutting the ribs to remove the lung lobe containing the cancer. But it leaves a long scar, and patients take six months to recover from this invasive and risky procedure. over the last 20 years, a new technique has to the point.. thoracoscopy (VATS) video-assisted lobectomy instead of making a long incision in the chest and breaking ribs, surgeons simply make small holes to reach the target area Their actions are guided by a video camera miniature inserted into the chest wall through one of the holes.
"The technique is beneficial, but it is not practiced, because the risk of major bleeding, it is difficult to control. Pulmonary arteries are thin and fragile in case of bleeding during open surgery, then it is easy. But sew us and that when we work with a camera and he is bleeding and we can not see through the lens, the patient. may die quickly, because the pulmonary artery is directly connected to the heart, "said Dr. Liberman
to facilitate and secure the process, it uses a new tool :. a kind of gun with a small three millimeters jaw at the end which seals the blood vessels using ultrasonic energy. the device, called HARMONIC ACE® + 7 Shears was designed by Ethicon, part of Johnson & Johnson. It is commonly used to seal small blood vessels of less than seven millimeters in diameter. Dr. Lieberman hopes to demonstrate that the ultrasonic spray is also effective for the branches of the pulmonary artery.
After five years of pre-clinical studies CRCHUM, first with animals, then in phase 1 and 2 clinical trials that have demonstrated the safety of the procedure, Dr. Liberman is now leading a large clinical phase 2 multi-center to assess the effectiveness of the technique in 150 patients in Canada, the US, and Europe. The $ 1.8 million project is funded by Johnson & Johnson. The results should be available in four years.
Each year, lung cancer kills about 1.59 million people in the world, largely due to smoking, which is responsible for 80% of cases, according to the World Health Organization . Cancer is particularly alarming because it is often diagnosed late, and the survival rate five years after diagnosis is rather low :. 17% of women and 14% men
Dr. Liberman hopes the new surgical approach he developed to save lives. "I think this will decrease the risk of bleeding and reduce postoperative pain. Patients will be able to resume their normal lives faster," he said.
Monic Ste-Marie had the . his luck lung cancer was diagnosed quickly Six months after the medical procedure vanguard that saved her life, she is doing well. ". I had pain for a month after the operation now, I still have trouble catching my breath, but that's normal, "she said
