ABSTRACT
Despite the availability of various modalities to locate small non-palpable pulmonary nodules during minimally invasive thoracoscopic surgery, precise lung nodule resection remains a challenge. Pre-operative localization techniques add additional time, expense, and complication rate. Intra-operative localization methods, such as ultrasound, may be a real-time solution, but challenges remain with visualizing deep parenchyma lesions and operator-dependent use. Many thoracoscopic wedge resections are performed using a combination of pre-operative imaging and intra-operative landmarks. Although usually cost and time-efficient, the problem occurs when a wedge resection is performed, and the nodule is not within the specimen. This case report describes the use of the O-arm Surgical Imaging System, a full-rotation imaging system that provides three-dimensional cone-beam imaging, in an 81-year-old male patient with a solid 8 mm left lower lobe lung nodule. After two unsuccessful wedge resections, we used the O-arm and finally resected the nodule with a negative surgical margin. The O-arm provided instant feedback regarding the nodule status, allowing a standard thoracoscopy room to function as a hybrid operating room without the need to reposition the patient. Rather than convert to a thoracotomy, proceed to a larger resection, or experience a missed nodule, the O-arm proved to be a helpful intra-operative tool to find a missing lung nodule.
