An endoscopic retrograde cholangiopancreatography (ERCP)-based algorithm for the management of pancreatic pseudocysts.
In the treatment of pancreatic pseudocysts, percutaneous and endoscopic drainage have, in certain cases, become alternatives to surgery. However, each treatment modality carries risks of complications and recurrences that may be minimized by the appropriate allocation of therapy. This article proposes the use of an endoscopic retrograde cholangiopancreatography (ERCP)-based algorithm as a means to allocate pseudocyst therapy based on the findings of pancreatic duct obstruction or pseudocyst communication. To evaluate this algorithm, the records of a series of patients with pancreatic pseudocysts seen at Duke University Medical Center from 1984 to 1990 were reviewed. Of 102 patients, 73 had symptomatic pseudocysts that required treatment. Forty of the 69 elective interventions were preceded by ERCPs and retrospectively applied to the algorithm. The number of adverse outcomes (treatment failures + complications) of the group that followed the algorithm was 3 of 26 (12%), while the number of adverse outcomes of the group that did not follow the algorithm was 6 of 14 (43%) (p less than 0.04 by Fisher's exact test). These two subgroups were similar in all other characteristics examined. Therefore, this ERCP-based algorithm may be used to allocate pseudocyst treatment; however, a prospective trial is necessary to prove its efficacy.
