EUS-guided ethanol ablation in patients with solid pseudopapillary neoplasm: a four-case series.

Background/aims: Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare tumor with low malignant potential, though 10-15% may show invasive or metastatic behavior. This study aimed to evaluate the safety and efficacy of endoscopic ultrasound-guided ethanol ablation (EUS-EI) in patients with SPN who were not surgical candidates.

Methods: Four patients with SPN who declined or were ineligible for surgery underwent EUS-EI at Aichi Cancer Center.
