Background: The true efficacy of EUS-guided ethanol lavage (EEL) of pancreatic cystic neoplasms is unclear. This study aimed to assess long-term outcomes and adverse events of EEL by using a standardized protocol. Methods: Single-center, prospective, pilot study in which participants with suspected mucinous cyst neoplasms or branch duct intraductal papillary mucinous neoplasms ≥1 cm in maximum diameter underwent EEL with 80% ethanol. Follow-up cross-sectional imaging was obtained to assess for changes in cyst volume. Results: Twenty-three patients underwent EEL (57% male, mean age 70 years). Mean duration of follow-up was 40 months (range 9-82 months). Mean calculated final concentration of ethanol achieved in treated cysts was 50% (range 0%-79%). Complete resolution of pancreatic cystic neoplasms occurred in 2 participants (9%). When stratified into those participants who achieved ≥80% versus
