Using Endoscopic Ultrasound to Sample Intra-Abdominal Lymph Nodes

Many endosonographers do not perform these biopsies, but they probably should.

Many patients are found to have enlarged intra-abdominal lymph nodes (adenopathy) on cross-sectional imaging of unclear etiology. These patients are often referred for CT-guided or surgical biopsy. Endoscopic ultrasound–guided fine-needle aspiration (EUS FNA) can also be used to evaluate intra-abdominal lymph nodes, but many endosonographers have little or no experience with this procedure.

To determine the diagnostic accuracy of EUS FNA in this setting, investigators in China conducted a meta-analysis of 12 studies involving 774 patients undergoing EUS FNA of enlarged intra-abdominal lymph nodes. The overall pooled sensitivity of EUS FNA for lymphadenopathy was 94%, the pooled specificity was 98%, the pooled positive likelihood ratio was 17…
