Algorithm for selection of lymph nodes undergoing EUS FNA. When more than one lymph node was identified in a specific location, the one with the greater number of malignant EUS criteria (more suspicious) was initially selected for EUS FNA. The procedure was terminated if either suspicious cells were found on the smear or no additional lymph nodes were found on the EUS examination.
