Endoscopic ultrasound-guided injective ablative treatment of pancreatic cystic neoplasms

Table 1 Different injective ablative treatment methods

Agent	Concentration	Infusing method	Injected volume	Agent left
Ethanol	80%-100%, mainly 80%-99%	Single agent	50%, 90%, or 100% of the fluid extracted from the cyst	No ethanol
Ethanol + paclitaxe	Ethanol: 99%; paclitaxel: 2 mg/mL, 3 mg/mL, or 6 mg/mL	Paclitaxe was injected after the full aspiration of ethanol	Equal to the volume of cyst fluid aspirated	All paclitaxel
Lauromacrogol	10 mg/mL	Single agent	Ensuring the cystic wall completely soaked in solution	Mainly 2-10 mL lauromacrogol
Paclitaxel + gemcitabine	Paclitaxel: 3 mg/mL; gemcitabine: 19 mg/mL	Mixed to make a paclitaxel-gemcitabine cocktail	Equal to the original amount aspirated and the upper limit is 8 mL	All cocktail
