It seems from recent feedback from surgeons performing lung surgery that the goal of achieving full resolution of all air leaks is both difficult to attain and practically perhaps not essential. Surveying our customer feedback as expressed in theatre recently it seems that while air leak resolution is of course an ideal, in cases where air leak is widespread the goal of air leak resolution extends as far as enabling reinflation of the lung. Our experience in complex cases such as decortication definitely brings it home that full air leak resolution may be beyond any sealant option, while achieving sustainable reinflation is the most desirable intraoperative goal.
