Endoscopic ultrasonography‐guided ethanol‐lipiodol ablation of small neuroendocrine tumors: What volume should we inject?

We read with interest the manuscript by Choi et al. (1), which describes EUS-guided ethanol-lipiodol ablation (EUS-ELA) of 40 neuroendocrine tumors (NETs) in 33 patients. The inclusion criteria were a diameter <2, low suitability for surgery, or refusal of surgery. By reading the article it is not clear the volume of the EL solution that was injected to obtain ablation of NETs. This article is protected by copyright. All rights reserved.
