[Internal pancreatic fistula. Presentation of a new case]

Internal pancreatic fistulas are a well-known complication of chronic pancreatitis and should be added to the classic complications of malabsorption, diabetes, pain and pseudocyst. The fact that it is an infrequent complication (Bradley compiled about 200 reported cases in 1982) motivated us to make this clinical report. The importance of total parenteral nutrition (NPT), which leads to cure in 50% of these patients, and the usefulness of endoscopic retrograde cholangiopancreatography (ERCP) are evaluated in the cases in which surgery is contemplated.
