†, other procedures include combined pleural biopsy and wedge resection, combined lobectomy and lymphadenectomy, VATS biopsy, resection of posterior mediastinal mass, and lobectomy that was converted to thoracotomy; ‡, class I surgical site infections are defined as clean wounds (non-traumatic wound, noninflamed, no break in technique, no entry of the infection into the gastrointestinal, genitourinary or respiratory tract or oropharynx); §, perioperative interventions include pressure to resolve a minor staple line bleeding, a drain for a leak, a resection of additional lung tissue to release a reinforced reload that got stuck and could no longer be opened (the only device-related adverse event), and two other interventions to address a leak and a bleed that occurred away from the buttressed staple line; ¶, pre-discharge reinterventions were the insertion of a drain to address the air leak that developed postoperatively and the exchange of the drain type.
