The management of pancreatic pseudocysts (PPs) has traditionally been surgical. Although
highly effective, surgery may be associated with a complication rate of 35% and a
mortality rate of 10%. This has encouraged the development of nonsurgical approaches.
Percutaneous puncture and aspiration under US or CT guidance have been used, but aspiration
alone was found to be ineffective, because of high recurrence rates, up to 71%. Continuous
percutaneous drainage with indwelling catheters reduces the relapse rates but may
be associated with a complication rate, ranging from 5% to 60%. Complications include
fistula formation, infection, and bleeding.
