Pancreatic adenocarcinoma recurrence after surgery (PARaS) is associated with poor outcomes. PARaS is locoregional in 50%-80%, effecting the resection bed and adjacent lymphatics.1-3 Detection of PARaS via endoscopic ultrasound (EUS) is challenging because recurrent malignancy is difficult to distinguish from normal postoperative changes. Diagnosing PARaS is important, because salvage chemotherapy/radiation improves survival.4,5 The purpose of this investigation is to determine the clinical utility of EUS fine-needle aspiration (FNA) in patients with suspected PARaS.
