Abstract:

Background and purpose: Lung cancer is currently the greatest threat to human life and health of the malignant tumor, clinical examination revealed a solitary pulmonary nodules (SPN), including a significant portion of early stage lung cancer. The research aimed to discuss the diagnosis value of CT guidance Hookwire positioning thoracoscopic surgery for solitary pulmonary nodule. Methods: From Jul. 2011 to Jun. 2013, 310 SPN patients in the Department of Thoracic Surgery of Fudan University Shanghai Cancer Center were collected. Hookwire positioning pins were retained guided by CT scan into the patients’ body. Video assisted thoracic surgery (VATS) pulmonary wedge resection was adopted. According to the result of intraoperative frozen pathology, further treatment method was decided. Positioning accuracy, complications, VATS lung wedge resection surgery successful rate, transfer rate in the chest and SPN pathological classification and other indicators were calculated with statistical methods. Results: Hookwire positioning successful rate was 100%, meanwhile, 2 patients with hemoptysis received symptomatic treatment. Intraoperative Hookwire fell off in 12 patients (3.87%), VATS wedge resection surgery successful rate was 99%, transit thoracotomy was carried out in 3 patients. SPN postoperative histological pathology results: 237 cases with primary lung cancer, 73 cases with benign lesions. Conclusion: The method of CT guided Hookwire thoracoscopic surgery after positioning in treatment of SPN has higher diagnostic accuracy rate, reliable curative effect, fewer complications and great value in clinical promotion.
