ABSTRACT
OBJECTIVES:
The aim of this study was to evaluate a new self-expanding tract sealant device, designed to prevent pneumothorax after computed tomography (CT)-guided lung biopsy, as an intraoperative marker for small pulmonary nodules or ground-glass opacities during minimally invasive thoracic surgery.METHODS:
Three patients with pulmonary nodules underwent CT-guided biopsies in our radiology department. During the same procedure, using a 19-gauge coaxial needle, a self-expanding tract sealant device was positioned in the lung nodule to be used not only for the prevention of pneumothorax but also as an intraoperative marker. A few days later, conventional thoracoscopic surgery was scheduled. A visual examination was performed. The site of the deployment of the BioSentry device was determined by checking for the proximal end of it beyond the visceral pleura. Thoracoscopic wedge resections using endoscopic staplers were performed to confirm histological characteristics, surgical margins and correct placement of the plug.RESULTS:
Three consecutive patients underwent CT-guided placement of this self-expanding tract sealant device (BioSentry) before surgery, without complications. The thoracoscopic resection was performed with success. The plug was easy to visualize with the scope, and all removed nodules had surgical free margins and the plug was correctly positioned in all patients.CONCLUSIONS:
The self-expanding tract sealant device was created for the reduction of pneumothorax and chest tube placement rates after percutaneous lung biopsy. We used it for the first time for intraoperative localization of peripheral small solid nodules or ground-glass opacities with good results.
