Trial Information

Endoscopic Ethanol Ablation of Communicating Pancreatic Cystic Neoplasms

Subjects will undergo EUS and/or ERCP as outpatients. For cysts shown to communicate with
the main pancreas duct, a balloon catheter will be placed in the main pancreatic duct via
ERCP. The balloon catheter will isolate the cyst from the main pancreatic duct, allowing
ethanol injections of the cyst. A pancreatic duct stent will be placed in some patients,
requiring repeat endoscopy for removal at another time.

Inclusion Criteria:

- Presence of a pancreatic cystic lesion, at least 2 cm in maximum diameter

- Cyst may communicate, or definitely communicates, with the pancreatic duct (based on
prior CT, MR, ERCP, or EUS images)

- Treatment of the cystic lesion is desired due to symptoms or concern for subsequent

- Age at least 18 years

- Able to give informed consent

- Surgical treatment has been considered and a surgical consultation offered to the
patient, OR the subject's cyst does not meet consensus criteria for surgical
resection. (Current consensus criteria for resection are one or more of the
following: cyst is symptomatic, ≥ 3 cm in diameter, contains a mural nodule, cytology
of cyst fluid is positive for malignancy, or main pancreatic duct diameter is > 6

Exclusion Criteria:

- Known or suspected pregnancy, or nursing

- History of pancreatitis within 3 months prior to study endoscopy procedures

- Cyst has a primarily microcystic architecture on EUS
