Poor recruitment

Pancreatic cysts are becoming diagnosed more frequently due to the increased use and sensitivity of imaging. A subset of these cysts are pre-cancerous, therefore suggested treatment is surgery for removal. However, surgery involves significant risks and emerging opinion suggests that not all cysts need to be surgically removed. An alternative therapy would be ideal, in particular for those where surgical risk outweighs the benefits of resection. Ethanol and paclitaxel ablation of pancreatic cysts may be a viable alternative to surgical resection.

Our hypothesis is that ethanol with paclitaxel ablation is a safe and effective method for treatment in those with per-cancerous, mucinous pancreatic cysts.

Inclusion Criteria:

2. Cyst size > 15mm but <50mm

3. 3 or fewer cyst compartments

4. Age ≥18 and ≤ 85

Exclusion Criteria:

1. Inability to safely undergo EUS examination with standard conscious sedation
2. Inability for safe FNA needle insertion into the cyst (eg: intervening vessel)

5. Active pancreatitis or pancreatic infection
6. Active sepsis/bacteremia
7. Inability to provide informed consent
