Abstract

Background: Positron emission tomography (PET) is commonly employed to detect distant metastatic disease in patients with known or suspected cancer. When the PET demonstrates uptake near the esophagus, stomach, duodenum, or rectum, EUS can be used to evaluate these areas to confirm or exclude malignant disease. The effectiveness of EUS for this indication is not known. The aim of this study was to evaluate the impact of EUS with or without FNA on the clinical management of patients with positive PET scans.
