n this single-center study we analyze patients who underwent elective PD from January_2014 to December_2017. Patients are divided into two groups: standard PD (ST-PD)vs PD with external biliary stent(PD-BS). Demographic, preoperative, intraoperative, and postoperative variables will be analyze, including complications according to the Clavien-Dindo classification, and those specific to pancreatic surgeries, and mortality rates within 90 days of operation.
Postoperative pancreatic fistula(POPF) is the most common complication of pancreaticoduodenectomy (PD). Sometimes POPF is associated with biliary fistula(BF), or mixed fistula. The purpose of this study is to assess whether the severity of the fistulae, when present, is decreased with an external biliary stent in place.
