EUS-guided Choledochoduodenostomy vs ERCP as First Line in Malignant Distal Obstruction (CARPEDIEM Trial)

May 2, 2026 updated by: Joan B Gornals, Hospital Universitari de Bellvitge

Endoscopic Ultrasound-Guided Biliary Drainage With Lumen-Apposing Stent vs Classical ERCP for First-line Therapy of Malignant Distal Biliary Obstruction: An Open-label, Multicenter Randomized Trial (CARPEDIEM Trial)

The aim of this clinical trial is to evaluate the biliary drainage technical failure rate and/or the postprocedure acute pancreatitis rate between EUS-CDS vs ERCP procedures in patients with distal malignant biliary obstruction.

Detailed Description

Ecoendoscopy-guided choledochoduodenostomy (EUS-CDS) has been extended as a second line treatment in cases of ERCP failure in malignant distal biliary obstruction (MDBO). However, there are clinical trials which have compared it with ERCP as a first line treatment for MDBO in palliative patients, showing similar clinical and technical success and adverse events (AEs) rate between both techniques. Data about the benefit of this techique in potentially surgical patients is still limited.

Recent retrospective study (Janet J et al, Ann Surg Oncol 2023) and two recent meta-analysis (Barbosa E et al, GIE 2024; Gopakumar H et al, AM J Gastr 2024; both with > 500 cases) found that EUS-CDS group had significantly less technical failure rate and less postprocedure pancreatitis rate.

Thus, our hypothesis is that EUS-CDS has benefits in terms of decreasing those rates (technical failure, postprocedure pancreatitis) when compared to ERCP in MDBO in potentially surgical patients with resectable and borderline disease.

Description

Inclusion Criteria:

  • Malignant distal biliary obstruction diagnosed in patient considered RESECTABLE or POTENTIALLY RESECTABLE/BORDERLINE with biliary drainage indication: i) impaired hepatic enzymes (including hyperbilirubinemia) x3 times upper the superior normal value. ii) Radiologic singns of extrahepatic bile duct obstruction with presence of retrograde dilatation, of at least 12-mm axial diameter.
  • Consensual malignancy by a bilio-pancreatic multidisciplinar committe (histological confirmation is not mandatory)
  • Patient capable of understanding and/or singning the informed consent.
  • Patient who understands the type of study and will comply with all follow-up tests throughout its duration

Exclusion Criteria:

  • Pregnancy or lactation.
  • Severe coagulation disorder: INR > 1.5 non correctable with plasma administration and/or platelet count < 50.000/mm3.
  • Distal malignant biliary strictures in patients considered directly resectable, non-surgical, unresectable, or palliative
  • Benign or uncertain etiology of biliary strictures or strictures located proximally or in close proximity to the hilum.
  • Patients with prior biliary stents or other biliary drainages (e.g., PTCD).
  • Altered intestinal anatomy due to prior surgery that prevents or hinders papillary access (e.g., gastric bypass, Billroth II, duodenal switch, Roux-en-Y).
  • Stenosis in the antral or duodenal region that prevents access to the duodenum and reaching the papilla.
  • Situations that do not allow for upper gastrointestinal endoscopy (e.g., esophageal stricture).
  • Patients with functional diversity, who lack the capacity to understand the nature and potential consequences of the study, except when a legal representative is available.
  • Patients incapable of maintaining follow-up appointments (lack of adherence).
  • Lack of informed consent.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: ERCP with SEMS

Endoscopic retrograde cholangiopancreatography (ERCP) with deployment of a self-expandable metallic stent (SEMS). Gold standard in malignant distal biliary obstruction (MDBO) in current practice.

ERCP technique: Cannulation with papillotome (advanced cannulation techniques are allowed). Sphincterotomy. Self-expandable metallic stent (SEMS) deployment.
Procedure: Endoscopic biliary drainage
Decompression of the bile duct by endoscopic aproach.
Device: Self-expandable metallic stent (SEMS)

Self-expandable metallic stent (SEMS) deployment:

Covering: Uncovered or Partially Covered. Non covered if gallbladder is present.

Size: 10x40mm or 10x60mm or 10x80mm.
Experimental: EUS-CDS with LAMS-Pigtail

Echoendoscopy-guided Choledochoduodenostomy (EUS-CDS) with deployment of a lumen-apposing metal stent (LAMS) and axis-orienting double-pigtail plastic stent throug LAMS.
