  • Title: Percutaneous drainage of pancreatic pseudocysts: a prospective study.
    Author: D'Egidio A, Schein M.
    Journal: World J Surg; 1992; 16(1):141-5; discussion 145-6. PubMed ID: 1290254.
    Abstract:
    We classify pancreatic pseudocysts in 3 types: post-necrotic type I, related to acute pancreatitis; post-necrotic type II, related to an acute attack superimposed on chronic pancreatitis; and retention type III, due to chronic pancreatitis with ductal stricture. A prospective study on percutaneous catheter drainage of post-necrotic pseudocysts (type I and II) was undertaken from 1987 to 1990. Twenty-three pseudocysts in 21 patients were drained. Overall recurrence rate was 4%; 2 patients had fistulization of the catheter into bowel; no deaths occurred. The procedure was successful in all type I cysts; in type II cysts it was associated with prolonged drainage and increased risk of complications when cyst-duct communication was present. Percutaneous drainage has no role to play in type III retention cysts. Guidelines regarding indications for treatment and the techniques employed are described.
