Bronchopleural fistula with associated empyema after pneumonectomy, although uncommon, is a serious and potentially lethal complication. This is reinforced by this retrospective review presented by Hollaus and associates of 96 patients in which 65 patients (67%) died. Although there was a wide spectrum of presentations, it is of interest that of the 49 patients initially treated with operation by a variety of procedures, 20 (41%) died and 21 (43%) were dismissed with healed wounds. Of the 36 patients initially treated with bronchoscopy, 5 (14%) died, in 11 (31%) the fistula healed, and only 4 (11%) left with a healed wound. Also, 12 patients who had failed bronchoscopic treatment underwent secondary surgical procedures, with two additional deaths.
Treatment should result in an alive patient with a healed wound. Prevention is paramount. Meticulous closure of the bronchus, leaving a short bronchus to prevent pooling of secretions and subsequent infection, and not contaminating the pleural space during the course of the procedure are all important in preventing this complication. Also, a previously irradiated bronchus should be reinforced with vascularized tissue at the time of the initial operation.
Our current treatment plan after stabilization of the patient is (1) open drainage by an Eloesser flap or reopening of the original thoracotomy, (2) reclosure of the bronchus reinforced with vascularized tissue, preferably transposed muscle, and (3) when the fistula is healed, obliteration of the pleural space by a Clagett maneuver. Although invasive and time consuming, this can lead to a successful outcome in many patients. Pairolero and associates [1] reported on 45 patients with a postpneumonectomy empyema of whom 28 had an associated bronchopleural fistula. Following the above plan, the bronchopleural fistula was successfully closed in 24 of the 28 patients (86%). There were three operative deaths (11%), all in patients in whom the fistula could not be successfully closed. Of 31 patients in the entire group, Clagett closure was ultimately successful in 26 (84%).
My colleagues and I continue to believe aggressive treatment of postpneumonectomy bronchopleural fistula and empyema provides the best opportunity for a successful long-term result.
