Single Plastic Stent Vs. Fully Covered Self-Expanding Metal Stent on Benign Biliary Stricture Secondary to Chronic Pancreatitis
Sponsor: Changhai Hospital
Summary
The goal of this clinical trial is to compare the efficacy and safety of a single plastic stent versus a fully covered self-expanded metal stent in relieving benign biliary stricture secondary to chronic pancreatitis. The main questions it aims to answer is: Whether the efficacy of a single plastic stent is non-inferior to that of a fully covered metal stent in patients with benign biliary stricture secondary to chronic pancreatitis？ Participants will be randomly assigned to receive either a single plastic stent (SPS) placement or fully covered self-expanded metal stent placement treatment for 6 months, and they will be followed up for 18 months.

Interventions
endoscopic retrograde biliary drainage (single plastic stent)
Participants will undergo ERCP. A flexible tube is inserted into the duodenum, crossing the sphincter of Oddi to access the biliary system. And the location, diameter, and length of biliary stricture will be evaluated by injection of contrast media. A single plastic stent is then placed across the biliary stricture, allowing the bile duct to resume drainage. The participants will be observed closely after ERCP and record complications. Imaging evaluation will be conducted 6 months after stenting to confirm spontaneous passage of the biliary duct stent, and the stent will be removed via ERCP if it is still in place.
