Study Design: There will be a total of 10 patients undergoing this experimental surgical procedure once meeting all entry criteria and subsequent to obtaining informed consent. Follow-up endoscopic examination will be conducted approximately 6 weeks following the procedure to determine the success of the drainage of the pseudocyst. Longer term follow-up will be determined by the patient's overall condition. These 10 patients will be compared to a retrospective review of 10 patients to compare pseudocyst size, degree of pain and hospital length of stay. The degree of pain will be assessed using the Wong-Baker Pain Scale. The retrospective series will be a matched cohort based on size of the pseudocyst and age and comorbidities of the patient.
