PHOENIX – Each year more than 250,000 patients present with ground-glass opacities and other solitary pulmonary nodules, and they are difficult to locate.
“There’s been a need for our field to develop new technologies to find these nodules in the OR,” Dr. Sunil Singhal said in a video interview at the annual meeting of the Society of Thoracic Surgeons. “The fallback plan has always been that we can make a thoracotomy. Some studies have shown that in about one out of every two cases you end up opening a patient just to find a tiny little nodule.”
Dr. Singhal of the division of cardiothoracic surgery at the University of Pennsylvania School of Medicine, Philadelphia, discussed preoperative and intraoperative localization methods, including an investigational technology in which patients receive an intravascular dye that localizes the pulmonary tumor. “When we put our video-assisted thoracoscopic surgery camera in, the tumors are glowing,” he said. “We can then do a localized wedge excision and confirm margins of the staple line. We’ve done this [in] about 80 patients, and it’s been non-toxic, very safe, and very effective. Our biggest limitation has been our depth of penetration.”
Dr. Singhal reported having no financial disclosures.
