Comparison of Preoperative CT Scan Guided and Intraoperative Hybrid DynaCT Scan-Guided Small Lung Tumor Localization

We will perform intraoperative lung tumor localization in CGMH hybrid operation room(Room 51) equipped with the Siemens Artis Zeego system with DynaCT imaging capabilities. The system provides images equivalent to a 16-slice spiral CT scanner in a single 6-s sweep.

Preoperative localization of the lung nodule will be carried out in the radiology department on the day of surgery using local anesthesia. CT-guided hook-wire or methyl blue dye will be placed percutaneously through a 22-gauge needle with the distal end deep to the nodule. The patient will then be taken to the operating room, where under general anesthesia with lung isolation, the nodule will be removed by wedge excision with endostaplers (Endo-GIA-II, United States Surgical,Norwalk, Conn; Echelon Endostapler, Ethicon Endo-Surgery, Cincinnati,Ohio) under the guidance of preoperative lung marking. If the lesion could not be excised using the VATS technique, the patient underwent an open thoracotomy.
