Pak J Chest Med Jan ;27(3):133-9.

Background: Bronchoscopy is the examination of the airways with flexible or rigid endoscopes. The advantage of the flexible bronchoscope is that it can help in investigation of bronchioles for any findings. Bronchoscopy has progressed from a diagnostic tool to interventional and endobronchial ultrasound (EBUS) bronchoscopy in recent decades. Objective: Objective of the present study was to know indications, diagnostic yield and complications of Flexible Fiberoptic Bronchoscopy. Methodology: We looked at the medical records of 153 individuals who had a bronchoscopic surgery at the Medical Teaching Institute, Lady Reading Hospital in Peshawar between September 2020 and September 2021, using patient files, bronchoscopy suit records and hospital HMIS. Before the procedure, each patient or patient`s relative signed a written informed consent form. Demographic information, comorbidities, indications for the procedure, radiological findings, bronchoscopy findings, final diagnosis, and bronchoscopy complications were all obtained. Results: Of 153 patients, 91 (59%) were men. Majority of the participants (52%) were above 60 years of age. Hypertension (40%) was predominant comorbidity, followed by DM-II (39%), Asthma (22%) and others. 40% patient had significant exposure to tobacco smoke. The primary indication for bronchoscopy was suspected pulmonary infections (27%), followed by suspected malignancy or a lung mass on CT (23%) and hemoptysis. Other indications include, bilateral hilar LN, Undiagnosed lung infiltrates in immunocomprised patients etc. Overall diagnostic yield was 51%. The most common finding on chest X-ray was air space shadowing, followed by lung mass, hilar lymphadenopathy and cavity formation. Other less common features on Xray and CT included interstial opacities and others. 13% of the X-rays and 2.6% of the CTs were reported as normal. Conclusion: Bronchiscopy procedure help in disease prevention and findings of different disease like different chest infections, smear-negative TB, and malignancy. In detecting of these illness and other respiratory disorders, Flexible Bronchoscopy has a critical importance rule. Furthermore, it is a safe method with a high diagnostic yield for a variety of patients with respiratory illnesses.
