Pancreatic fistula

Pancreatic fistula is one of the serious complications of acute and chronic pancreatitis after abdominal surgery, especially after pancreatic surgery and trauma. The definition of Yeo and Cameron in Creutzfeldt-Jakob surgery is: pancreatic duct rupture caused by various reasons, and pancreatic fluid leaked from the pancreatic duct for more than 7 days is pancreatic fistula. Pancreatic fistula is divided into extrapancreatic fistula and intrapancreatic fistula. The pancreatic juice flows out of the surface through the abdominal drainage tube or incision as an extrapancreatic fistula; the intrapancreatic fistula includes a pancreatic pseudocyst, pancreatic pleural ascites, and fistula between the pancreatic duct and other organs, such as a pancreatic tracheal fistula. If pancreatic fluid flows into the abdominal cavity but is surrounded by surrounding organ tissues, an intrapancreatic fistula is formed. It is customarily called an intrapancreatic fistula as a pancreatic pseudocyst, but its essence is still pancreatic fistula.
