Rigid Bronchoscopy: A Life-Saving Intervention in the Removal of Foreign Body in Adults at a Busy Tertiary Care Unit.

Introduction Foreign body (FB) aspiration is a potentially lethal emergency and is not uncommon in adults. Rigid bronchoscopy (RB) is a useful procedure for the extraction of these FBs, and it has a high success rate. The aim of this study was to document the clinical presentation of FB aspirations and management outcomes of non-vegetative FB extraction using RB as a therapeutic modality. Method This prospective interventional study was conducted in the Department of Thoracic Surgery, Jinnah Postgraduate Medical Centre (JPMC), Karachi from May 2019 to April 2020. Patients of both genders of ages 12 years or above, presenting with FB aspiration were included. RB was performed in all patients. Results Chest radiograph (CXR) identified FBs in all 60 patients, 51 of whom were females and nine males. In 24 (40%) patients, a CT scan was performed to accurately localize the FB. Left bronchus was the most common location of the FB (n=39; 65%). Scarf pin was the most common type (n=45; 75%) of FB, followed by sewing needle (n=7; 11.7%), safety pin (n=5; 8.3%), and tire repair needle (n=3; 5%). In 53 (88.3%) patients, RB was successful in retrieving the FB. Thoracotomy was performed in the remaining seven patients due to inaccessibility. One (1.7%) patient died due to the rupture of the thoracic aortic aneurysm. Conclusion Accidental aspiration of pins and needles can be fatal in adults. RB is a life-saving modality for safely removing these FBs. However, thoracotomy should be used as a life-saving procedure in cases of FBs affecting secondary bronchi or beyond.
