A comparison of efficacy and safety of preoperative versus intraoperative computed tomography-guided thoracoscopic lung resection.
Journal of Thoracic and Cardiovascular Surgery 2018 July 21
BACKGROUND: The efficacy and safety of intraoperative computed tomography (IOCT)-guided lung tumor localization and resection performed in a hybrid operating room (OR) compared with the conventional 2-stage preoperative CT (POCT)-guided approach for the treatment of small and deep solitary pulmonary nodules (SPNs) remains unknown.
METHODS: We compared IOCT-guided (IOCT group) and POCT-guided (POCT group) thoracoscopic resections in 64 consecutive patients with SPNs. The main outcome measures included efficacy, safety, and radiation exposure.
RESULTS: The IOCT (n = 34) and POCT (n = 30) groups had a similar SPN depth-to-size ratio. All SPNs were successfully localized and removed using a minimally invasive approach. There were no significant intergroup differences in localization procedural time (mean, 17.68 [IOCT] vs 19.63 minutes [POCT]; P = .257) and radiation exposure (median, 3.65 [IOCT] vs 6.88 mSv [POCT]; P = .506). The use of a hybrid operating room (OR) for tumor localization significantly reduced the patient time at risk (ie, the interval from completion of localization to skin incision; mean, 215.83 [POCT] vs 13.06 minutes [IOCT]; P < .001). However, the IOCT-guided approach significantly increased the time under general anesthesia (mean, 120.61 [POCT] vs 163.1 minutes [IOCT]; P < .001) and the total OR utilization time (mean, 168.68 [POCT] vs 227.41 minutes [IOCT]; P < .001).
CONCLUSIONS: Compared with the POCT-guided approach, the IOCT-guided approach decreased the time at risk, despite a significant increase in the global OR utilization time. Because no significant outcome differences were evident, the choice between the 2 approaches should be based on the most readily available approach at a surgeon's specific facility.
