Pancreatic ascites has the characteristics of highly proteinaceous, amylase-rich intraperitoneal fluid. It usually occurs as a result of rupture of a pseudocyst or disruption of main pancreatic duct during the course of acute or chronic pancreatitis. It can be managed by traditional conservative methods including fasting, total parenteral nutrition and ascites tapping or surgical interventions. Recently, several cases of treating pancreatic ascites with somatostatin analogue (octreotide) successfully have been reported. We experienced a patient with chronic pancreatitis and pancreatic ascites, who was successfully treated by somatostatin analogue (octreotide). (Kor J Gastroenterol 2000;35:517 - 521)
