EUS guided drainage of pancreatic pseudocysts (PPC’s), abscesses and fluid collections (PFC’s)

Abstract

Fluid collections around the pancreas occur as a sequel to an attack of acute pancreatitis, or less often secondary to ductal obstruction in chronic pancreatitis. Not all fluid collections around the pancreas are called pseudocysts (PPC’s). A PPC is a well demarcated collection of fluid rich in pancreatic enzymes and having a well defined wall of fibrous or granulation tissue [1]. Formation of a PPC requires at least 4 weeks from the onset of pancreatitis. Before 4 weeks, it is called a pancreatic fluid collection (PFC). PPC’s are usually sterile. In presence of pus, they are called pancreatic abscess. Some amount of solid debris is often found in the floor of a PPC, even without active infection [1].
