Publication Evaluation of the diagnostic yield of lung cancer on various Bronchoscopic modalities Authors(Nepalese Respiratory Society, 2023) Shahi, Rejina; Bhatta, Narendra; Verma, Avatar; Upreti, Augraj; Gurung, Kum Bahadur; Chaudhary, Sabnam; Dhakal, Nishchal; Mishra, Deebya RajAbstract: Background: The application of cytological techniques in identifying malignant respiratory tract lesions has been widely praised as a significant achievement. Flexible fiberoptic bronchoscopy has greatly transformed respiratory cytology, making procedures such as bronchial brushings, broncho-alveolar lavage, and bronchial forceps biopsy more convenient, accessible, and popular. Methodology: All the suspected cases of lung cancer from 1st Jan, 2020 - 31st Dec, 2022 fulfilling inclusion criteria who have undergone flexible bronchoscopy in our center have been analyzed and enrolled in the study. Results: Out of 90 patients, 85 were found to be malignant. Squamous cell carcinoma was the most common carcinoma (31.1%) followed by adenocarcinoma (26.7%), non-small Cell Lung Carcinoma (17.8%) and small cell carcinoma (12.2%), majority of the cases were of 6-7th decade of life and were smoker. Sensitivities of Bronchoalveolar Lavage (BAL), Bronchial brush, Endobronchial forceps Biopsy (EBB), Transbronchial Lung Biopsy (TBLB) and Transbronchial Needle Aspiration (TBNA) were found to be 32%, 87%, 83%, 55% and 69% respectively. Diagnostic accuracy of BAL, bronchial brush, EBB, TBLB and TBNA were found to be 36%, 87%, 83%, 55% and 61% respectively. Conclusion: With a greater sensitivity (87%) and diagnostic accuracy (87%), bronchial brushing shows great promise as a convenient cytological technique suitable for screening ambiguous cases and early detection of lung cancer, as it saves the time required for processing biopsy samples.Publication Flexible bronchoscopy for removal of airway foreign bodies: A single center experience Authors(Nepalese Respiratory Society, 2023) Dhungana, Ashesh; Shrestha, Prajowl; Shrestha, Deepa Kumari; Verma, Avatar; Oli, Ritamvara; Thakur, LaxmanAbstract: Background: Airway foreign bodies are rare in occurrence and challenging to manage. The presentation varies depending upon the size, site, and nature of the aspirated material. Although rigid bronchoscopy is the preferred choice in children; distally lodged foreign bodies in adults have high success rate of extraction with flexible bronchoscope. Objective: The aim of this study is to evaluate the utility of flexible bronchoscopy for removal of airway foreign bodies in adolescents and adults. Methods: In a retrospective study conducted between January 2018 to March 2024 at National Academy of Medical Sciences, Bir hospital; medical records of patients undergoing bronchoscopy for airway foreign bodies were extracted. Methods and Material: Demographic parameters, type and location of foreign body, extraction procedure, accessory equipment used, and the success rates were analyzed. Complications during and after the procedure were also recorded. Results: During the study period, a total of 3143 bronchoscopies were performed, of which 18 (0.57%) were done for foreign body extraction. Patients were aged between 12 to 89 years; cough was the commonest symptom and lobar collapse was the commonest radiological sign. Organic foreign bodies accounted for 61% cases and inorganic 39%. Right lower lobe was the commonest site. Successful flexible bronchoscopy assisted extraction was achieved in 89%. Of the 18 patients, 12 (67%) were successfully removed with rat toothed forceps and five (28%) with basket device. No major complications were noted. Conclusions: Flexible bronchoscopy has a high success rate in management of airway foreign bodies and should always be considered as first line in adults.Publication Metabolic Signature and Obstructive Sleep Apnea in Nepalese Patients(Nepalese Respiratory Society, 2023) Verma, Avatar; Bhatta, Narendra; Mishra, Deebya Raj; Shahi, Rejina; Uprety, Augraj; Aryal, Prakash; Yadav, Devesh Kumar; Lama, UrmilaAbstract: Introduction: Untreated Obstructive Sleep Apnea (OSA) causes sleep related symptoms and also causes increased incidence of RTA, cardiovascular diseases and all cause mortality. Currently OSA has been recognized as the consequence of number of interrelated metabolic and oxidative pathologies. As there are limited data of association of OSA with metabolic stress and its correlation with severity of OSA, study of metabolic profile of these patients in view of defining the Metabolic signature of OSA was carried out in eastern Nepal. Objectives: To study metabolic profile of OSA and its association with clinical severity. Methods: Hospital based descriptive cross sectional study. Biochemical profile results related to metabolic –oxidative pathway of the OSA patients were obtained. Quantitative and qualitative data were obtained. Quantitative data were compared using Mann–Whitney test while qualitative variables compared using Pearson χ2. Correlation was carried out using Pearson and Spearman’s test. P-value<0.05 considered significant. Results: 33 patients of OSA were enrolled. Majority of patients had deranged metabolic and oxidative parameters despite mild OSA. Among metabolic stress parameters, most commonly deranged were decreased high density lipoprotein (HDL), increased mean arterial pressure (MAP), waist circumference (WC) and raised fasting blood sugar (FBS). Increased MAP and increased WC was significantly corelated with severity. Conclusion: Besides symptom complex, OSA is also harbinger of metabolic stress that can lead to various cardiometabolic diseases and premature mortality thus early recognition and treatment can mitigate these consequences.Publication Ultrasound-Guided Percutaneous Transthoracic Biopsy by Pulmonologists(Nepalese Respiratory Society, 2024) Verma, Avatar; Bhatta, Narendra; Shahi, Rejina; Lama, Urmila; Aryal, Prakash; Pantha, Srijan; Hamal, Sangita; Mishra, Deebya RajAbstract: Background: Ultrasound-guided transthoracic needle biopsy (USG-TTNB) is a simple and safe procedure carried out to obtain a tissue sample for confirmation of the diagnosis of various thoracic pathologies. These procedures are usually carried out by radiologists in our country. However, there is good efficacy and fewer complications even in the hands of chest physicians, as shown by many studies published abroad. Considering this, the study is carried out to evaluate outcomes of USG-TTNB by pulmonologists in Nepal. Objective: To study the efficacy and complications associated with USG-guided transthoracic needle biopsies performed by pulmonologists. Methods: Retrospective analysis of 77 patients undergoing USG-TTNB by pulmonologists at BPKIHS from November 2019 to November 2023 were analyzed. The efficacy of the procedure and the complication rate were derived. Efficacy was calculated as proportion of the patients who had undergone the biopsy and resulted in a clinically contributory specimen. Results: Mean age: 62.5 ± 13.7 years; 63.6% female. Transthoracic Fine Needle Aspiration showed a diagnostic yield of 82.6 % of patients, whereas that of trucut biopsy was 86.7 % with a combined diagnostic yield of 94 %. Pneumothorax occurred in four (5.2 %) of patients, and hemothorax occurred in two (2.6 %) of patients. Conclusion: USG-guided percutaneous transthoracic biopsy by a pulmonologist is a procedure with good diagnostic yield and a lower complication rate.
