Abstract:
Objective:To investigate the diagnostic value of rapid on-site evaluation (ROSE) technique in the mucosal biopsy under respiratory endoscopy in children with active tuberculosis.Methods:Clinical data of 40 patients with active tuberculosis diagnosed in Department of Respiratory Intervention, Qilu Children′s Hospital, Shandong University from June 2017 to January 2020 were retrospectively analyzed.Results:(1) There were 33 cases of tracheobronchial tuberculosis and 7 cases of tuberculous pleurisy in the 40 cases, among them 9 cases were difficult to diagnose.(2)Among 33 cases of tracheobronchial tuberculosis, 24 cases (72.7%) of caseous necrosis breaking into the lumen, and 9 cases (27.3%) of mucosal swelling and external pressure.Cytological ROSE (C-ROSE) showed granuloma, epithelioid cells and lymphocytic infiltration with all bronchial mucosal biopsies.Different positives results of microbiological ROSE (M-ROSE) in different biopsy parts: positive results were found 6 times at caseous necrosis (13.6%, 6/44 times), 4 times at granulation hyperplasia (12.5%, 4/32 times), 2 times at hyperemia and edema (22.2%, 2/18 times), 0 time at yellow-white necrosis, and 54 times at the junction between lesions and normal mucosa (81.8%, 54/66 times). The mucosal pathology showed granuloma, exudation and necrosis, including 22 cases with tuberculous granuloma, 5 cases with characteristic tuberculous nodules, and 11 cases with positive acid-fast staining.(3)Seven cases of tuberculous pleurisy, serious pleural adhesion, pleural hyperemia and edema were observed under thoracoscopy.After clearing the adhesive tape, scattered caseous miliary nodules were found in pleura in 4 cases with a difficult clinical diagnosis.The C-ROSE of smear on thoracoscopic biopsy were characterized by necrotic and histopathic cell, with multinucleated giant cells, but granuloma was rare.M-ROSE in different parts: 8 times positive for millet nodules (80.0%), 0 time positive for adhesion band, 2 times positive for congestion oedema (14.3%); biopsy pathology showed granuloma and necrosis, with 3 cases characteristic tuberculosis nodules and 2 cases positive for anti-acid staining.(4)Pathogenic microorganisms were detected in 19 children using next generation sequencing (NGS) and Mycobacterium tuberculosis/Rifampicin resistance real-time nucleic acid amplification detection technology (Xpert MTB/RIF), including 7 positive for NGS (36.8%), 8 positive (42.1%) and 5 positive for both NGS and Xpert MTB/RIF (26.3%).Conclusions:Respiratory endoscopy combined with ROSE technique has important clinical significance in early diagnosis of active tuberculosis in children, and it is worth of promotion and applying.
