Image-guided video-assisted thoracoscopic surgery (iVATS): a single center experience and review.

Abstract

Lung cancer screening techniques using low-dose computed tomography (LDCT) scans have improved over the last decade. This means that there is an increased rate of detection of small, often non-palpable, nodules and ground-glass opacities. Obtaining a definitive diagnosis of these nodules using techniques such as percutaneous image-guided biopsy or intraoperative localization is challenging, and these nodules have traditionally undergone routine surveillance. Image-guided video-assisted thoracoscopic surgery (iVATS), which is performed in a hybrid operating room, has made it more feasible to biopsy and resect these nodules. The first thoracic surgery hybrid operative room was introduced at our institution at Brigham and Women's Hospital. Herein, we describe our experience implementing this technique including the methods we used to train key personnel such as radiologists, surgeons, and anesthesiologists to ensure that this technique successfully translated to a clinical setting. We review the benefits of iVATS, which includes decreased rate of fiducial dislodgement, real-time imaging which facilitates successful fiducial placement, and smaller sized resection of lung parenchyma. We will also describe the comparisons between traditional diagnostic methods and iVATS, patient selection criteria and important technical details. Some centers describe alternative techniques for several of the technical aspects, including patient positioning, which we also mention. Lastly, we describe adverse events after iVATS, which are comparable to those seen after a standard VATS.
