Pseudocyst management: endoscopic drainage and other emerging techniques

Abstract

Pseudocyst formation is a well known complication of pancreatitis. Not all pancreatic pseudocysts require intervention. Selected patients who are asymptomatic can be subject to expectant management. Spontaneous resolution has been shown to occur in 40% to 50% of patients with no serious complications occurring during the observation period. Intervention is warranted if the patient is symptomatic, there is a progressive increase in size or if the pseudocyst is infected. Surgery was the only available treatment for pseudocysts for a long time. Of late other modalities like percutaneous, endoscopic, and laparoscopic drainage have come to be seen as viable alternatives.
