Flexible Fiberoptic Bronchoscopy: Indications, Diagnostic Yield and Complications

Area of Science:

• Pulmonology
• Respiratory Medicine
• Diagnostic Procedures

Background:

• Flexible fiberoptic bronchoscopy (FFB) is a cornerstone in diagnosing and managing diverse respiratory ailments.
• Assessing the utility of FFB in a clinical setting is crucial for optimizing patient care.

Purpose of the Study:

• To evaluate the primary indications for FFB.
• To determine the diagnostic yield of FFB across various respiratory diseases.
• To assess the safety and complication rates associated with FFB procedures.

Main Methods:

• Retrospective review of 216 patients undergoing FFB between July 2009 and June 2012.
• Analysis of indications, diagnostic outcomes for different respiratory conditions, and recorded complications.
• Data collection included patient demographics, procedure details, and etiological findings.

Main Results:

• FFB was performed for diagnostic purposes in 91.7% of cases, with an overall diagnostic yield of 46%.
• Mycobacterium tuberculosis (MTB) and malignancy were the leading indications.
• High diagnostic yields were observed for eosinophilic pneumonia (100%) and pulmonary infiltrates in HIV patients (85.7%).
• Complications were infrequent (1.5%), with no mortality reported.

Conclusions:

• FFB is a safe and valuable procedure for diagnosing respiratory conditions, particularly infections like MTB and malignancies.
• The diagnostic efficacy of FFB is notably high in specific conditions such as eosinophilic pneumonia and HIV-associated pulmonary infiltrates.
• FFB serves as an essential tool for both diagnostic and therapeutic interventions in respiratory medicine.
