Agar blue localization of small pulmonary nodules and ground glass opacifications for thoracoscopic resection.

BACKGROUND: Screening for lung cancer using high resolution computed tomography (CT) has produced encouraging early results. Extremely small nodules and non-palpable areas of opacifications are able to be detected, but pose a challenge to the thoracic surgeon trying to resect these areas. METHODS: Forty five patients with ground glass opacifications (GGOs) or small pulmonary nodules underwent pre-operative CT-guided placement of methylene blue dyed agar and/or hook wire needle localization prior to thoracoscopic resection. Progel was applied to any intraoperative air leaks observed after successful resection. RESULTS: All lesions were successfully excised thoracoscopically. The blue agar aided in localization of these areas and did not affect the histological architecture during pathologic evaluation. CONCLUSIONS: Careful pre-operative evaluation and planning, including use of selective CT-guided blue agar localization and hook wire placement, may greatly assist in thoracoscopically locating and resecting these often difficult-to-visualize lesions.

AVATS: Awake Video Assisted Thoracic Surgery--extended series report.

BACKGROUND: Traditionally, video-assisted thoracic surgery (VATS) is performed under general anesthesia with selective ventilation and endotracheal intubation. Although some sparse data exists on VATS under local anesthesia, most series reserve this technique for pleural-based surgery. Performing VATS under local anesthesia may extend the benefits of this procedure to those unable to tolerate general anesthesia and improve outcomes. METHOD: We have extended this technique to include more complex procedures, with results that surpass traditional open thoracotomies. We analyzed 293 patients who underwent awake video-assisted thoracic surgery (AVATS) from June 2010 to January 2014. RESULTS: Procedures such as pleural biopsies, wedge resections, decortications, and even lobectomies were able to be safely performed using AVATS technique with comparable or better results than VATS under general anesthesia. CONCLUSION: AVATS is a feasible technique with equal or improved outcomes without compromise in safety. Further study may help delineate the role of this technique in the care of the thoracic surgical patient.
