JM van der Klooster, AF Grootendorst, JW Brouwers, A Late Presentation of Postpneumonectomy Pleural Empyema and Bronchopleural Fistula. 1998; 18(6): 567-569 To the Editor. Bronchopleural fistula (BPF) is a rare but serious complication after pneumonectomy. The recognition and diagnosis of bronchial stump disruption can be very difficult and may lead to a delay in the management of this life-threatening condition. Modern high-technology imaging techniques, such as fiberoptic bronchoscopy, computed tomography and ventilation scintigraphy, are generally used to identify the site of persistent air leakage. Bronchography is rarely of value in detecting small leaks, but has been useful in the demonstration of large ones. 1 We would like to highlight the use of methylene blue as a safe, effective and relatively noninvasive means of confirming the diagnosis of an occult postpneumonectomy BPF with pleural empyema. Little attention has been paid to this simple bedside test since 1955, when Franz et al. reported a 33.3% yield in their 24 patients who had pulmonary resections.2 As most cases of postpneu-monectomy BPF develop within days, weeks, or at the most, months of the operation, it should be noted that our case is an unusual late-presenting variant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
