Bronchoscopy in adults at a tertiary care centre: indications and complications.

ABSTRACT

Fibreoptic bronchoscopy (FOB) helps in visualisation of the endobronchial tree. Fibreoptic bronchoscopies were done in 429 cases between January 1999 and January 2000 [322 men (75.1%) and 107 women (24.9%)]. Patients were between 12 and 89 years of age (mean+/- SD = 49 +/- 15.1 years). Of which, 196 (45.7%) had lung cancer and 233 (54.4%) had non-malignant disease [Tuberculosis (TB) 26, miliary TB 16, non-resolving pneumonia 29, atypical pneumonia 10, bronchiectasis 11, aspergillosis 12, sarcoidosis 17, interstitial lung disease (ILD) 20, haemoptysis with normal chest x-ray 13 and miscellaneous 79]. In this series of 429 patients a significant number of patients (n = 127) presented with fever (38 malignant and 89 non-malignant disease, p < 0.0001), 137 had haemoptysis (74 malignant and 63 non-malignant disease, p < 0.01), 89 had chest pain (61 malignant and 28 non-malignant disease, p < 0.0001) and 29 patients presented with complaint of anorexia (21 malignant and 8 non-malignant disease, p < 0.003). High prevalence of lung lesions in the right upper lobe [10.4% (43 of 411)] and left main bronchus [12% (49 of 411)] was observed. Left upper lobe showed 8.7% (36 patients) lesions and right middle lobe showed 5.5% (23 patients) lesions. In 143 (34.8%) patients, FOB findings were normal. Out of 407 patients, FOB was suggestive of necrotic/nodular growth in 159 patients (39.1%), infiltrative growth in 8 patients (1.9%), and extrinsic compression was found in 39 patients (9.6%). In 143 patients (35.2%) no endobronchial growth was seen. Bronchial biopsy (BB) was performed in 162 (37.8%) patients, transbronchial lung biopsy in 56 patients (13.1%), bronchial washing for cytology in 350 patients (81.5%), bronchial washing for AFB in 302 patients (70.3%), bronchial washing for culture in 67 patients (15.6%), bronchial washing for fungus in 64 patients (14.9%) and Pneumocystis carinii infection was looked for in 6 patients (1.4%). Postbronchoscopy complications were recorded as follows Early termination of FOB due to decreased O2 saturation in 10 cases (2.4%), postbiopsy bleeding in 5 cases (1.2%), post FOB fever in 5 cases (1.2%), chest pain in 7 patients (1.7%) and pneumothorax occurred in 2 patients (0.5%). FOB performed in outpatient setting is a useful and safe modality. Most patients in whom FOB was done in the present setup had suspected lung cancer. No major complications were encountered.
