EUS-guided ethanol ablation for pancreatic cystic lesions
EUS-EA for PCLs was accomplished using the following protocol (Video).
- The longest diameter was measured
- 80% of the cystic fluid was aspirated, after which 99% ethanol was injected and stored in the cyst for 1 min
- Step number 2 was repeated twice, but retention time was prolonged to 3~5min
- All injected ethanol and remnant cystic fluid was aspirated
