Preliminary results of anatomic lung resection using energy-based tissue and vessel coagulative fusion technology.
OBJECTIVE
Mechanical stapling devices have been established as the mainstay of therapy in the selective isolation and division of bronchial and vascular structures during anatomic lung resection. Few data are available regarding the application of energy-based tissue fusion technology during anatomic lung resection. In the present study, we evaluated the use of energy-based instruments for the division of the pulmonary arterial and venous branches during anatomic lung resection.


METHODS
Anatomic lung resection (segmentectomy or lobectomy) was performed using energy-based coagulative fusion technology. A low-profile jaw can be used to facilitate dissection in both open and video-assisted thoracic surgery cases, applying a seal 6 mm wide by 22 mm in length. Two energy applications were applied to the arterial and venous branches before vessel division.


RESULTS
The bipolar tissue fusion system was used in 211 patients between 2008 and 2010 (104 lobectomies and 107 anatomic segmentectomies). Initially, we used a device with a smaller, curved jaw (n = 12), producing a 3.3- to 4.7-cm seal. No arterial dehiscences and 2 partial venous dehiscences that were recognized and controlled intraoperatively occurred. For the remaining cases, we used a new device with a larger jaw that applied a seal 6 mm wide by 22 mm in length. No arterial or venous dehiscences (vessel size range, 0.4-1.2 cm) occurred.


CONCLUSIONS
The bipolar tissue fusion system provided safe and reliable control of pulmonary arterial and venous branches during anatomic lung resection. The use of energy-based tissue fusion technology represents a reasonable alternative to mechanical stapling devices during anatomic lung resection.
