Pancreatic pseudocysts and fluid collections: percutaneous approaches.

Radiological imaging and intervention play important roles in the management of pancreatic fluid collections and pseudocysts. Computed tomography evaluation of the severity of pancreatitis and assessment of its course are now routine. Percutaneous drainage of pancreatic pseudocysts and abscesses is commonly performed as an adjunct to surgical treatment and is frequently definitive therapy. Percutaneous débridement of pancreatic necrosis has recently emerged as a viable alternative to open surgical treatment.
