Air Leaks: Aerosol glycerine System
A range of different leak will be done with different needle sizes on the lung. Perform localization on staple lines used surgically during pulmonary surgeries, as they are known to not consistently give an airtight closure. The lung will be put in the ex-vivo model and ask for a surgeon to localize the leaks with our system. The needle incisions will be repeat on another lung and ask the same surgeon to localize the leaks with the submersion test. To perform the submersion test the surgeon will have to submerge the lung in saline solution and to check the presence of air bubbles. The lung is inflated to pressures of 20 to 40 cm H209. The precision of both systems will be compared by the minimal incision the minimal incision the surgeon was able to localize.

About This Trial
Air leaks represent one of the most common complications and postoperative morbidity in thoracic surgery. Air leaks have been associated with the largest preventable morbidity associated with increased costs following lobectomy (typically related to increased length of stay). However, the standard used to detect and localize the air leaks, the submersion test, is not suitable for the standard surgical procedure, Video Assisted Thoracic Surgery. Considering the prevalence of this complication and the absence of a surgical standard of care for such complications, the aim of this study is to develop a system to create and send a glycerine aerosol smoke in the lungs of the patient. The smoke is visible with standard laparoscope and will flow though the pulmonary leak, thereby reducing postoperative surgical complications, morbidity, and length of stay for patients undergoing pulmonary resection.
