Antibiotic Prophylaxis Is Not Required for Endoscopic Ultrasonography-Guided Fine-Needle Aspiration of Pancreatic Cystic Lesions, Based on a Randomized Trial

Background & AimsGuidelines recommend routine antibiotic prophylaxis for patients undergoing endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) of pancreatic cysts, but there is conflicting evidence for its necessity. We investigated whether performing the procedure without antimicrobial prophylaxis increases the incidence of infection.MethodsWe performed a multicenter, randomized, noninferiority trial to compare prophylaxis with...
