Efficacy and safety of endosonography-guided transvascular needle aspiration of thoracic and abdominal lesions: A systematic review and meta-analysis.
Journal of Clinical Ultrasound : JCU 2023 May
BACKGROUND: The diagnosis of intrathoracic and abdominal masses is challenging when lesions are located behind major vessels. Endoscopic ultrasound (EUS) or endobronchial ultrasound (EBUS)-guided transvascular needle aspiration (TVNA) provides a potentially useful diagnostic tool for such lesions. Data with respect to the safety and outcome of E-TVNA are scarce. Hence, this meta-analysis was conducted to assess the critical role of E-TVNA for diagnosis of various lesions.
METHODS AND MATERIAL: A meta-analysis was performed by pooling the data from studies obtained from comprehensive search of Medline, Embase, and Scopus from January 2000 to September 2022. The outcomes analyzed included sample adequacy, diagnostic accuracy and adverse events including bleeding.
RESULTS: A total of 17 studies (n = 411) were included in the final analysis. The pooled rate of sample adequacy was 91.5% [95% confidence interval (CI): 86.8-96.2], while the pooled rate of diagnostic accuracy was 85.0% (95% CI: 78.9-91.2). The pooled rate of bleeding with E-TVNA was 1.4% (95% CI 0.0-3.1%). All the episodes of bleeding were mild and resolved without any further intervention. There was no significant heterogeneity with respect to various outcomes and results were comparable on sensitivity analysis.
CONCLUSIONS: E-TVNA offers a safe and accurate diagnostic modality for the diagnosis of mediastinal and abdominal lesions located on the other side of major vessels. Selection of potential candidates and close periprocedural observation are essential to improve the outcome.
