Pancreatic cysts are common, and some pancreas cysts have malignant potential. Usual treatment of these cysts is either observation or surgical removal of part or all of the pancreas. Minimally invasive treatment via endoscopy has been described, using endoscopic ultrasound (EUS) guided ethanol injections. Such studies exclude cysts that communicate with the main pancreatic duct, to avoid burning the main pancreatic duct with ethanol. In this study, pancreas cysts communicating with the main pancreas duct are treated with ethanol via endoscopic retrograde cholangiopancreatography (ERCP) and/or EUS.

Primary Outcome Measures:
  • Occurrence of adverse events requiring treatment or hospitalization [ Time Frame: 3 days, 30 days ] [ Designated as safety issue: Yes ]
  • Decrease in volume of the pancreatic cyst by cross-sectional imaging studies (CT or MR) performed before and after treatment [ Time Frame: 6 months, 12 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 25
Study Start Date: January 2010
Estimated Study Completion Date: January 2015
Estimated Primary Completion Date: January 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cyst ethanol lavage
Subjects receiving the study intervention
Procedure: EUS and/or ERCP with ethanol injections of pancreatic cyst
Lavage of cyst with 80% ethanol
Other Names:
  • Alcohol lavage
  • Alcohol injection
  • Ethanol lavage
  • Ethanol injection
  • Endoscopic treatment
  • Pancreas cyst ablation

Detailed Description:

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.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

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 malignancy
  • 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 mm.)

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
