Biliary Externalization After Pancreaticoduodenectomy

Prospective Study Correlating External Biliary Stenting and Pancreatic Fistula Following Pancreaticoduodenectomy

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.

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.

Inclusion Criteria:

• Provision of informed consent
• Patient age > 18 years old;
• Elective pancreaticoduodenectomy performed for primary pancreatic disease.

Exclusion Criteria:

• Pancreaticoduodenectomy with multivisceral resection (organ other than duodenum, pancreas, gallbladder, and bile duct);
• Patients with peritoneal or liver metastases found during surgery.
