Trial of Identifying the Lung Intersegmental Plane by Iron Sucrose Injection Staining

This is a protocol to determine the safety and feasibility of using Iron Sucrose Injection to identify the lung intersegmental plane. This is relevant because the detection of small and early lung cancer is becoming increasingly common. segmentectomy may become a more prominent procedure for early-small lung cancer. One of the most difficult aspects of complete segmentectomy is detection of the intersegmental plane while maintaining an adequate surgical margin and remaining lung function. The method used to detect the intersegmental plane remains controversial. It is hoped that this technology can be used to recognize the intersegmental plane on the pleural surface and the pulmonary parenchyma and will save lots of money for patients in developing countries.
