Introduction<br />
Bronchoscopy is a useful diagnostic tool used by physicians to diagnose diseases including lung cancer and<br />
tuberculosis (TB) and is often done in line with radiological imaging to aid diagnosis. This audit was designed<br />
to review results obtained from bronchoscopies and its correlation with radiological diagnosis.<br />
Methods<br />
140 patients that had undergone bronchoscopy from May 2010 to January 2011 in Hospital Selayang<br />
were included. Demographic data, radiological interpretations and bronchoscopy results were collected<br />
retrospectively from clinical notes.<br />
Results<br />
Majority of the patients were inpatient (49.3%), male (65.7%) and Malay (50%). Average age was 54.8 years.<br />
The main indication was to rule out TB (36.4%) or malignancy (33.6%), to find the aetiology of the radiological<br />
abnormalities (23.6%) and to rule out opportunistic infection (5.7%). 48.6% had abnormal findings while 20%<br />
were suspicious of malignancy. 59.3% of biopsies and 42.9% of brushings were positive for malignancy. Of<br />
the bronchoalveolar lavage (BAL) findings (n=138), 7.1% were positive for malignancy and 2.2% showed<br />
features of tuberculosis. For those procedures done to rule out TB (n=51), 19.6% were found to be smear<br />
positive and 37.3% were culture positive. Out of the bronchoscopies done for suspected malignancy (n=47),<br />
36.1% had positive biopsy results, 6.4% had positive brushings and 21.3% had positive BAL cytology results.<br />
Bronchoscopy were only diagnostic in 7 cases out of those done to find out the aetiology of the radiological<br />
abnormalities (n=31). Bronchoscopy provided an alternative diagnosis in 10 cases and only confirmed the<br />
radiological suspected diagnosis in 44 cases.<br />
Conclusion<br />
From this audit, results gained from bronchoscopy overall had poor correlation with the diagnosis suspected<br />
radiologically.<br />
