Abstract
The method of locating pulmonary nodules before operation plays a crucial role in the surgery of pulmonary ground-glass nodules (GGNs). However, the methodologies surrounding intraoperative localization remains limited, with the majority procedures requiring specific additional equipment. We report a new approach in locating pulmonary GGNs by image-localized body surface marking intraoperative (IBMI) localization. A retrospective review of the medical records of 76 patients with pulmonary GGNs was performed. All patients underwent IBMI localization between January 2018 and March 2019. Twenty-six patients underwent CT-guided hook wire localization before IBMI localization during surgery. IBMI localization was undertaken directly without pre-treatment in the remaining patients. The efficacy and complications of this approach were analyzed and compared with other pre- or intraoperative localization methods in the current literature. The intraoperative localizations were performed successfully in 72 of all 76 patients pulmonary GGNs within a mean duration of 5.3±1.8 (range, 2.0 to 9.6) minutes. The GGNs in four cases were found to have a significant deviation (>1.5 cm) from the positioning points. All GGNs were successfully resected. Except for five cases of active chest wall bleeding (6.5%), no other intra- or postoperative complications occurred. The IBMI localization approach is a safe and short-duration procedure with high success rates and fewer complications. We used it for the first time for intraoperative localization of peripheral GGNs with excellent results.
