Publication Metastatic Supraclavicular Lymph Nodes among Patients with Lung Carcinoma in a Tertiary Care Centre: A Descriptive Cross-sectional Study(Nepal Medical Association, 2023) Lamichhane, Suman; Thapa, Ajit; Chataut, Dinesh; Suwal, Sundar; Ansari, Mukhtar Alam; Yadav, Birendra KumarAbstract Introduction: Metastatic spread of lung cancer to supraclavicular lymph nodes is considered distant metastasis for treatment purposes. Detection of supraclavicular lymph node metastasis in patients with lung cancer serves for tissue diagnosis by itself and also helps avoid more invasive biopsy from the primary lung mass itself. Ultrasonography of the lower neck can detect supraclavicular lymph nodes before they are palpable and can also be used for safe sampling of these lymph nodes. The aim of this study was to find out the prevalence of metastatic supraclavicular lymph nodes among patients with lung carcinoma in a tertiary care centre. Methods: A descriptive cross-sectional study done in a tertiary care center, carried out from 15 September 2019 to 14 September 2020. Ethical approval was obtained from the Institutional Review Committee (Reference number: 84(611)E2/076/077). The study was done among 92 patients with biopsy-proven lung cancer (lung mass or supraclavicular lymph node biopsy) who were referred for evaluation, and/or percutaneous transthoracic biopsy. Convenience sampling method was used. Point estimate and 90% Confidence Interval were calculated. Results: Among 92 patients with proven lung cancer, metastatic supraclavicular lymph nodes were seen in 13 patients (14.10%) (8.17- 19.73, 90% Confidence Interval). Among 13 patients with metastatic lymph nodes, 9 (69.23%) had palpable supraclavicular lymph nodes. The majority 11 (84.61%) had round-shaped lymph nodes. All metastatic lymph nodes showed loss of echogenic fatty hilum. A total of 12 (92.30%) metastatic lymph nodes showed a peripheral disorganized pattern of vascularity. Conclusions: The prevalence of metastatic supraclavicular lymph nodes was lower than in similar studies done in international settings.Publication Ultrasound Guided Biopsy among Patients with Lung Lesions Undergoing Procedures in Interventional Radiology of a Tertiary Care Centre(Nepal Medical Association, 2024) Kayastha, Prakash; Adhikari, Binaya; Paudel, Sharma; Suwal, Sundar; Shingh, Shashi Shekhar; Chapagain, Pradip; Regmi, Pradeep RajAbstract Introduction: Minimally invasive image-guided percutaneous core needle biopsy can obtain tissue samples for diagnosis of subpleural lung cancer, which is crucial for the correct management of lung lesions. Common complications of lung biopsy include pneumothorax, parenchymal haemorrhage and haemoptysis. The study aimed to determine the prevalence of ultrasound-guided biopsy among patients with lung lesions undergoing procedures in interventional radiology of a tertiary care centre. Methods: A descriptive cross-sectional study was performed in the Department of Radiology and Imaging from 1 August 2018 to 30 September 2019 after obtaining ethical approval from the Institutional Review Committee. USG-guided biopsy of peripheral lung lesions was performed with an 18 gauge semiautomatic biopsy instrument and a 17 gauge coaxial needle. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 188 biopsy of lung lesions, ultrasound-guided biopsies were performed in 28 (14.89%) (9.80-19.98, 95% Confidence Interval). Conclusions: The prevalence of ultrasound guided biopsy among lung lesions is lower than other studies done in similar settings.
