Comparison of a Short Modified Metal Stent Versus Plastic Stent as a Bridge to Surgery in Pancreatic Cancer With Malignant Biliary Obstruction (BRIDGE-8)

18 mai 2026 mis à jour par: Il Sang Shin, Soonchunhyang University Hospital

Multicenter Randomized Trial of a Short Modified 8-mm-diameter Fully Covered Metal Stent Versus Plastic Stent as a Bridge to Surgery in Pancreatic Cancer With Malignant Biliary Obstruction

This study is a multicenter, randomized clinical trial designed to compare the effectiveness and safety of a modified 8-mm fully covered self-expandable metal stent (FCSEMS) with a conventional plastic stent for preoperative biliary drainage in patients with pancreatic cancer and malignant biliary obstruction.

In patients who require biliary drainage before surgery, stent placement is commonly performed using endoscopic retrograde cholangiopancreatography (ERCP). However, the optimal stent type remains uncertain.

Participants will be randomly assigned to receive either the modified FCSEMS or a plastic stent. The primary objective is to evaluate the rate of stent-related complications requiring reintervention before surgery. Secondary outcomes include stent patency, adverse events, and surgical outcomes.

The results of this study are expected to help determine the most appropriate stent strategy for patients undergoing surgery for pancreatic cancer.

Description détaillée

Pancreatic cancer is a highly aggressive malignancy with a poor prognosis, and many patients present with malignant biliary obstruction at the time of diagnosis. Preoperative biliary drainage is frequently required in patients undergoing neoadjuvant chemotherapy or delayed surgery to relieve jaundice and prevent complications such as cholangitis.

Endoscopic retrograde cholangiopancreatography (ERCP) with stent placement is the standard approach for biliary drainage. Plastic stents (PS) are widely used due to their low cost and ease of removal; however, they are associated with a relatively short patency and frequent occlusion, often necessitating repeated interventions. Fully covered self-expandable metal stents (FCSEMS) have demonstrated longer patency, but concerns remain regarding adverse events and potential impact on subsequent surgical procedures.

A modified non-flared 8-mm diameter FCSEMS has been developed to reduce complications while maintaining adequate patency. Its design includes a dumbbell-shaped structure with a narrower central portion to prevent migration, a fully covered membrane to reduce tissue ingrowth, and a retrieval lasso to facilitate removal. This design may offer advantages over both conventional FCSEMS and plastic stents in the preoperative setting.

This study is a prospective, multicenter, open-label, randomized controlled trial designed to compare a modified 8-mm FCSEMS with a plastic stent for preoperative biliary drainage in patients with pancreatic cancer and malignant biliary obstruction. Eligible patients will be randomly assigned in a 1:1 ratio to receive either the modified FCSEMS or a plastic stent.

The primary endpoint is the stent-related non-event rate at the time of surgery, defined as the proportion of patients who do not require reintervention due to stent-related complications before surgery. Secondary endpoints include the incidence of recurrent biliary obstruction, time to recurrent biliary obstruction, stent-related adverse events, technical success, surgical outcomes, and overall survival.

All procedures will be performed using standard ERCP techniques by experienced endoscopists. Patients will be followed until surgery and throughout the postoperative period to assess clinical outcomes.

The findings of this study are expected to provide evidence to guide optimal stent selection for preoperative biliary drainage in patients with pancreatic cancer, particularly in the context of neoadjuvant treatment strategies.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: M-FCSEMS group
Participants in this arm will undergo endoscopic retrograde cholangiopancreatography (ERCP) with placement of a modified 8-mm fully covered self-expandable metal stent (FCSEMS) for preoperative biliary drainage.
Dispositif: Modified 8-mm Fully Covered Self-Expandable Metal Stent
A modified non-flared 8-mm fully covered self-expandable metal stent designed for preoperative biliary drainage. The stent features a dumbbell-shaped structure with a narrower central portion to reduce migration, a fully covered membrane to prevent tissue ingrowth, and a retrieval lasso to facilitate removal. It is deployed via ERCP across the malignant biliary stricture.
Autres noms:
  • M-FCSEMS
Comparateur actif: PS group
Participants in this arm will undergo endoscopic retrograde cholangiopancreatography (ERCP) with placement of a plastic stent (PS) for preoperative biliary drainage.
Dispositif: Plastic stent
A conventional 8.5-Fr plastic biliary stent used for preoperative biliary drainage. The stent is placed via ERCP across the malignant biliary stricture and represents the standard treatment option, although it is associated with shorter patency and a higher risk of occlusion compared to metal stents.
