[Bronchial fistula postpneumonectomy: predictive factors].

OBJECTIVE

To determine predictive factors of bronchial fistula following pneumonectomy.

METHODS

In 14 years (1989-2003), we collect 58 cases of bronchial fistula following 725 consecutive pneumonectomy in the service of thoracic surgery of the Sainte Marguerite Hospital in Marseilles. There were 53 cases (91.4%) of cancers and 5 cases (8.6%) of various pathology. The average age of the patients was of 61 +/- 10 years (range 24 to 80 years). The sex ratio M/F was 8.7. The software of regression SPSS (version11.5) was used to identify the factors risk of a bronchial fistula after a univariate and multivariate analysis.

RESULTS

The prevalence of the bronchial fistula after a pneumonectomy was 8%.The preoperative factors which increased to a significant degree the incidence of the bronchial dent to the univariate analysis were the chronic smoking (P < 0.001), the existence of COPD (P = 0.001) and of a previous thoracic surgery (P = 0.01). Operational data like a right- side pulmonary resection (P < 0.001), the type of bronchial stup carried out (P = 0.03) as and an extended pneumonectomy to the auricule (P = 0.03) were significant risk factors. With the logistic regression the significant risk factors were the chronic smoking (P = 0.002), the existence of COPD (P = 0.003), a previous pulmonary surgery (P = 0.03) and the right - side of the pneumonectomy (P < 0.001). The indication of the pneumonectomy was retained neither by the univariate analysis, nor by the logistic regression significant risk factors.

CONCLUSIONS

The predictive factors of a bronchial fistula after a pneumonectomy are dominated by respiratory co-morbidities. To prevent this complication, we insist on the stop of the tobacco, a better respiratory preparation and the acquisition of a protocol adapted of the bronchial stub after a pneumonectomy particularly on the right side.
