W175as "drain output of any measurable volume of fluid on or after postoperative day 3 with an amylase content greater than three times the serum amylase activity"
[11].The overall rate of pancreatic fistula after pancreaticoduodenectomy ranges from 17% in patients in whom the pancreatic remnant has a hard consistency
[12] and exocrine pancreatic function and pancreatic juice output are impaired
[13] to 25% in cases in which the pancreas is soft
[1], that is, the parenchyma is normal
[13]. Soft pancreatic texture
[1,3,13] and small pancreatic duct size
[3] are the most important preoperative risk factors for the development of pancreatic fistula.
The diagnosis of pancreatic fistula usually is made an average of 7 days after pancreaticoduodenectomy [5,14,15].
