Abstract

Background: Fiberoptic bronchoscopy (FOB) with transbronchial biopsy (TBB) is complicated by a pneumothorax in 1-4% of cases. Performance of routine post-TBB chest radiography (CXR) results in an extremely low diagnostic yield but nevertheless is the common clinical practice prevailing today. It has previously been suggested that routine post-TBB CXR could be avoided in asymptomatic patients. Objective: The objective of this study was to prospectively assess the feasibility and safety of this approach. Methods: The study group included 201 consecutive patients who underwent FOB with TBB at our institution between January 2009 and September 2014. All subjects completed a preprocedural, a 2-hour postprocedural, and a 24- to 48-hour postprocedural symptom questionnaire (chest pain, dyspnea, and cough). Post-TBB CXR was ordered by the treating physician only if indicated. All cases of pneumothorax were documented. Additionally, the following information was recorded: sex, age, immune status, indication for FOB, total number of biopsies done, lobe sampled, and pulse oxygen saturation. Results: Sixteen CXRs were ordered by the treating physician due to suspected pneumothorax (8%). Early-onset pneumothorax (i.e. within 2 h of TBB) was diagnosed radiologically in 6 patients (3%). Two late-onset pneumothoraxes (1%) were diagnosed more than 24 h after TBB. No pneumothoraxes of clinical significance were diagnosed among asymptomatic patients without significant oxygen desaturation events. Conclusions: Among asymptomatic patients without significant desaturation events, pneumothorax is rare and usually of negligible clinical significance. Therefore, performance of routine CXR after TBB is not necessary and can be safely avoided in this category of patients.
