New study tests safer bile duct drainage for cancer patients
NCT ID NCT06653192
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two procedures to relieve bile duct blockage caused by cancer. About 120 patients with pancreatic or bile duct cancer will be randomly assigned to get either a newer ultrasound-guided drainage or the standard ERCP procedure. The goal is to see which method has fewer failures and causes less pancreatitis.

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.
