BACKGROUND: Foreign body aspiration is an uncommon entity in adults. Herein, we describe our experience with flexible bronchoscopy in the removal of tracheobronchial foreign bodies in adults. We also conducted a systematic review of the literature on the topic of foreign body inhalation in adults managed with flexible bronchoscopy. METHODS: The bronchoscopy database (from 1979 to 2014) was reviewed for subjects > 12 y of age with a history of foreign body aspiration managed with flexible bronchoscopy. Demographic, clinical, and bronchoscopy data were collected and analyzed. PubMed was reviewed for studies describing the use of flexible bronchoscopy for foreign body extraction in adults. RESULTS: During the study period, a total of 25,998 flexible bronchoscopies were performed. Of these, 65 subjects (mean age of 32.8 y, 49 males) were identified who had undergone bronchoscopy for foreign body aspiration. Nonresolving pneumonia (30.6%), direct foreign body visualization (24.6%), and segmental collapse (18.4%) were the most common radiological abnormalities. Foreign bodies were identified in 49 cases during bronchoscopy and successfully removed in 45 (91.8%) subjects with no major complications. Metallic (41%) and organic (25.6%) foreign bodies were the most common. Shark-tooth (44.9%) and alligator (32.6%) were the most commonly used forceps in retrieving the foreign bodies. The systematic review yielded 18 studies (1,554 subjects with foreign body inhalation). In adults, the proportion of flexible bronchoscopy (6 studies, 354/159,074 procedures) performed for the indication of foreign bodies among the total flexible bronchoscopies was 0.24% (95% CI 0.18 -0.31). The overall success of flexible bronchoscopy (18 studies, 1,185 subjects) for foreign body extraction was 89.6% (95% CI 86.1-93.2). CONCLUSIONS: Foreign body aspiration is a rare indication for flexible bronchoscopy in adults. Flexible bronchoscopy has a high success rate in removal of inhaled foreign body and can be considered the preferred initial procedure for management of airway foreign bodies in adults.

Chronic obstructive pulmonary disease (COPD) is a major public health problem in India. Although several International guidelines for diagnosis and management of COPD are available, yet there are lot of gaps in recognition and management of COPD in India due to vast differences in availability and affordability of healthcare facilities across the country. The Indian Chest Society (ICS) and the National College of Chest Physicians (NCCP) of India have joined hands to come out with these evidence-based guidelines to help the physicians at all levels of healthcare to diagnose and manage COPD in a scientific manner. Besides the International literature, the Indian studies were specifically analyzed to arrive at simple and practical recommendations. The evidence is presented under these five headings: (a) definitions, epidemiology, and disease burden; (b) disease assessment and diagnosis; (c) pharmacologic management of stable COPD; (d) management of acute exacerbations; and (e) nonpharmacologic and preventive measures. The modified grade system was used for classifying the quality of evidence as 1, 2, 3, or usual practice point (UPP). The strength of recommendation was graded as A or B depending upon the level of evidence.

BACKGROUND: The use of endoscopic ultrasound with bronchoscope-guided fine-needle aspiration (EUS-B-FNA) has been described in the evaluation of mediastinal lymphadenopathy. Herein, we conduct a meta-analysis to estimate the overall diagnostic yield and safety of EUS-B-FNA combined with endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), in the diagnosis of mediastinal lymphadenopathy. METHODS: The PubMed and EmBase databases were searched for studies reporting the outcomes of EUS-B-FNA in diagnosis of mediastinal lymphadenopathy. The study quality was assessed using the QualSyst tool. The yield of EBUS-TBNA alone and the combined procedure (EBUS-TBNA and EUS-B-FNA) were analyzed by calculating the sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio for each study, and pooling the study results using a random effects model. Heterogeneity and publication bias were assessed for individual outcomes. The additional diagnostic gain of EUS-B-FNA over EBUS-TBNA was calculated using proportion meta-analysis. RESULTS: Our search yielded 10 studies (1,080 subjects with mediastinal lymphadenopathy). The sensitivity of the combined procedure was significantly higher than EBUS-TBNA alone (91% vs 80%, P ‫؍‬ .004), in staging of lung cancer (4 studies, 465 subjects). The additional diagnostic gain of EUS-B-FNA over EBUS-TBNA was 7.6% in the diagnosis of mediastinal adenopathy. No serious complication of EUS-B-FNA procedure was reported. Clinical and statistical heterogeneity was present without any evidence of publication bias. CONCLUSIONS: Combining EBUS-TBNA and EUS-B-FNA is an effective and safe method, superior to EBUS-TBNA alone, in the diagnosis of mediastinal lymphadenopathy. Good quality randomized controlled trials are required to confirm the results of this systematic review.
