BackgroundMechanical staplers are widely employed in minimally invasive anatomic lung resections, but have limitations when managing smaller pulmonary arterial and venous branches. Published data is lacking regarding the safety and efficacy of pulmonary vessel ligation using ultrasonic shears. We describe a single-surgeon experience employing ultrasonic shears for the ligation of pulmonary vasculature during lobectomy and segmentectomy, primarily in the setting of video-assisted thoracic surgery (VATS) resection.MethodsA retrospective chart review was conducted for all patients, who underwent anatomic resection, between 2008 and 2014. Charts were divided into 2 groups based on method of ligation (energy based or conventional). Dictated operative reports were reviewed and patient demographics, tumor characteristics, and complications were recorded.ResultsUltrasonic shears were used for pulmonary vessel ligation (5 to 6 mm) in 82 of 283 anatomic resections. A total of 118 vessels were ligated with ultrasonic shears. The majority of patients (83%) in the energy-based ligation group underwent VATS resection. There were fewer complications in the energy-based ligation group (26% vs 38%; p = 0.05); however, rates of intraoperative transfusion, prolonged air leak, empyema, and return to the operating room were similar across the 2 groups, and no statistically significant difference was found. There were no postoperative complications directly attributable to ultrasonic vessel ligation.ConclusionsEnergy-based ligation of small-diameter pulmonary vessels is a safe and useful adjunct in anatomic VATS resection and a viable alternative to mechanical stapling. Its narrow profile and thin blades make it ideal for ligation of pulmonary vasculature, particularly where the size and necessary clearance of mechanical staplers prohibit safe dissection.Copyright © 2016 The Society of Thoracic Surgeons.
