Plastic biliary stent patency in patients with locally advanced pancreatic adenocarcinoma receiving downstaging chemotherapy.

Background: Plastic stents in patients with biliary obstruction caused by pancreatic adenocarcinoma are typically exchanged at 3-month intervals. Plastic stents may have reduced durability in patients receiving chemotherapy.

Objective: To determine the duration of plastic biliary stent patency in patients undergoing chemotherapy for pancreatic adenocarcinoma.
