Introduction: Bronchopleural fistula is a rare but potentially fatal complication of pulmonary resections and proper management is essential for its resolution. In this study, we analyzed the incidence of fistula after pulmonary resection and reported data about endoscopic and conservative treatments of this complication., Methods: From January 2003 to December 2013, 835 patients underwent anatomic lung resections: 786 (94.1 %) had a lobectomy and 49 (5.9 %) a pneumonectomy. Bronchopleural fistula was suspected by clinical signs and confirmed by endoscopic visualization., Results: Eighteen patients (2.2 %) developed a bronchopleural fistula, 11 in lobectomy group (1.4 %) and 7 in pneumonectomy group (14.3 %). The fistula size ranged between <1 mm and 6 mm and mean time of fistula onset was 33.9 ± 54.9 days after surgery. Of 18 patients who developed fistula, one died due to acute respiratory failure and another one was reoperated and then died to causes unrelated to the treatment. All the remaining 16 patients were treated with a conservative therapy that consisted in keeping or replacing a drainage chest tube. Nine of them underwent also endoscopic closure of the fistula using biological or synthetic glues. The mean period of time elapsed for the resolution of this complication was shorter with combined (conservative + endoscopic) than with conservative treatment alone (15.4 ± 13.2 vs. 25.8 ± 13.2 days, respectively), but without significant difference between the two methods (p: 0.299)., Conclusion: Endoscopic therapy, associated with a conservative treatment, is a safe and useful option in the management of the postoperative bronchopleural fistula.

Objective: A bronchopleural fistula (BPF) is a serious complication after pulmonary resection and carries a high mortality rate. It remains a therapeutic challenge. The lack of a consensus suggests that no optimal therapy is available; however, endoscopic closure of a fistula may avoid extensive and potentially risky surgery., Methods: Seventeen patients (15 men and 2 women) with a BPF after a pneumonectomy (n = 2) or a lobectomy (n = 15), seen between 1995 and 2010, were reviewed. Their median age was 50 years (range, 14-75 years). Underlying diseases were malignant (n = 4) and nonmalignant (n = 13)., Results: The mean interval between surgery and fistula development was 20 days (range, 5-270 days). Clinical symptoms leading to a diagnosis of BPF were a persistent air leak (n = 2), a persistent air leak associated with pleural empyema (n = 3), pleural empyema alone (n = 11), and dyspnea (n = 1). Mean fistula size was 3.3 mm (range, 2-9 mm). Treatment consisted of oriented pleural drainage, adequate antibiotic therapy, and endoscopic closure of the fistula with local application of silver nitrate through a flexible bronchoscope (3-15 sessions, 3 times per week). Fistula closure was successful in 16 patients, but failed in 1 patient, who died from acute respiratory distress., Conclusions: BPF is a severe complication in thoracic surgery. The combination of pleural drainage, adequate antibiotic treatment, and mucosal application of silver nitrate, through a flexible bronchoscope, is an efficient alternative and avoids extensive surgical intervention., (Copyright © 2013 The American Association for Thoracic Surgery.

Objectives: Fistulas between the oesophagus and the respiratory tract can occur as a complication to anastomotic dehiscence after oesophageal resection, without any signs of local residual tumour growth. Other causes that are, by definition, benign may rarely prevail. The traditional therapeutic approach is to divert the proximal portion of the oesophagus and transpose the conduit into the abdominal cavity. With the introduction and development of self-expandable metal stents (SEMS), new therapeutic options have emerged for these severe complications. We have evaluated our stent-based strategy for managing these life-threatening situations., Methods: At Karolinska University Hospital, all patients admitted with an oesophago-respiratory fistula during the period 2003-2011 followed a stent-based strategy. On clinical suspicion, a prompt computed tomography scan was performed with contrast ingestion, to visualize the status of the anastomosis and the potential communications. Often an endoscopy was done to assess the oesophagus and the conduit. The respiratory tree was inspected through a concomitant bronchoscopy. The double-stent strategy presently applied meant that covered self-expandable metal stents (SEMS) were applied on the alimentary and airway sides to adequately cover the fistula orifice on both sides. The subsequent clinical course determined the ensuing therapeutic strategy., Results: During the study period, 17 cases with oesophago-respiratory fistulas were treated at our unit, of which 13 exhibited fistulation following an oesophageal resection due to cancer and 4 cases had a benign underlying disease. The cancer patients did not show any obvious demographic profile when it came to the cancer sub-location, histological type of cancer, or treatment with neoadjuvant chemo- and radiochemotherapy. There was an equal distribution between hand-sutured and stapled anastomoses. In 10 of the cases, the anastomoses were located in the upper right chest; the remainder in the neck, and all reconstructions were carried out by a tubulized stomach. The diagnosis of the fistula tract between the anastomotic area and the respiratory tract was attained on the 15th postoperative day (median), with a range from 5 to 24 days., Conclusions: When an oesophago-respiratory fistula is diagnosed, even in a situation where no neoplastic tissue is prevailing, attempts should be made to close the fistula tract by SEMS from both directions, i.e. from the oesophageal as well as the respiratory side. By this means, a majority of these patients can be initially managed conservatively with prospects of a successful outcome, although virtually all will eventually require a single-stage resection and reconstruction.
