Efficacy and Safety of Endoscopic Ultrasonography-Guided Ethanol Injections of Small Pancreatic Neuroendocrine Neoplasms: a prospective, multicenter study

Endoscopic ultrasonography (EUS)-guided ethanol injection (EI) has recently been introduced as one of the management strategies for pancreatic neuroendocrine neoplasms (PNENs). However, its role as a surgical alternative is unclear. We evaluated the efficacy and safety of EUS-EI in treating small PNENs through a prospective multicentre study.
