Core tip: Ethanol, a commonly used ablative agent, has been used to successfully and safely ablate solid and cystic hepatic lesions via percutaneous injection. Endoscopic ultrasonography (EUS)-guided ethanol ablation, a minimally invasive approach, was recently developed and has been successfully applied as treatment of pancreatic cysts, pancreatic neuroendocrine tumors, and abdominal metastatic lesions. Although it is not likely to replace radical resection for treating localized lesions or systemic therapy for managing metastatic tumors, EUS-guided ablation therapies represent an attractive alternative treatment modality for patients who refuse or are not eligible for surgery.
