Percutaneous Lung Nodule Resection With Sealing
UC Irvine, Irvine, CA, USA.
BACKGROUND:The Lung Cancer Screening Trial demonstrated that a 20% increase in lung cancer survival can be achieved by early detection and treatment. However, currently approximately 3% of patients eligible for lung cancer screening are referred by their physicians in great part due to the uncertainty and perceived risk of detecting a nodule and the interventions that may be required.METHODS: We have developed a device capable of removing a lung nodule percutaneously using advanced bipolar energy lung coring. Using a live porcine model under anesthesia,3cm cores of lung were obtained while sealing the lung as the coring element is advanced.RESULTS:In 5 trials to date a 1.2cm by 3 cm core of lung tissue was removed percutaneously with successful elimination of bleeding and air leak in a live animal model.CONCLUSION:Percutaneous lung nodule resection is possible without bleeding or air leak. This could result in greatly improved diagnostics, increased referral and lung cancer survival.
