Clinical utility of rapid on-site cytopathology

Published:August 23, 2016DOI:https://doi.org/10.1016/j.gie.2016.08.008
      EUS-guided FNA (EUS-FNA) is an important technique for evaluating pancreatic lesions, lymphadenopathy adjacent to the intestinal tract, and GI subepithelial lesions. Rapid on-site evaluation (ROSE) involves the immediate application of the EUS-FNA sample from the EUS needle to a slide that is quickly stained and examined, typically in the endoscopy suite. The samples may be evaluated by a cytotechnician, a cytopathologist, or both. The simplicity and utility of the ROSE technique are not typically appreciated by those not performing EUS. We present 4 case scenarios that demonstrate ROSE slide preparation and examination (Video 1, available online at www.giejournal.org; Fig. 1). The ROSE technique may improve diagnostic yield and allow for adjustments in EUS-FNA technique. In addition, if an immediate diagnosis of malignancy is made, patient care may be expedited.
