Eligibility
Inclusion criteria
Inclusion criteria: 1. Age 18 years or more at the time of obtaining informed consent. 2. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. 3. Findings on contrast-enhanced CT or contrast-enhanced MRI consistent with invasive pancreatic ductal adenocarcinoma. 4. Determined to have resectable (R) or borderline resectable (BR) pancreatic cancer based on abdominal contrast-enhanced CT or MRI, and scheduled to undergo neoadjuvant therapy. 5. Presence of distal biliary stricture on contrast-enhanced CT or MRI (defined as extrahepatic bile duct obstruction with the proximal end of the stricture located at least 2 cm distal to the hepatic hilum), for which biliary drainage is deemed necessary. 6. No prior biliary drainage for malignant biliary obstruction using plastic stent (PS), endoscopic nasobiliary drainage (ENBD), or self-expandable metal stent (SEMS). In addition, no prior percutaneous biliary drainage (percutaneous transhepatic biliary drainage (PTBD) or percutaneous transhepatic gallbladder drainage (PTGBD)) has been performed. (Prior procedures for benign diseases such as choledocholithiasis or cholelithiasis are permitted.) 7. Written informed consent for participation in the study obtained from the patient based on their free will. Neoadjuvant therapy, The treatment modality is not specified and may include radiotherapy.
Exclusion criteria
Exclusion criteria: 1. Concomitant acute cholangitis corresponding to Grade III (severe) according to the Tokyo Guidelines 2018. 2. Presence of gastrointestinal obstruction symptoms. 3. Suspected pancreatobiliary malunion based on imaging findings from CT, MRI, abdominal ultrasonography (AUS), or endoscopic ultrasonography (EUS). 4. Reconstructed gastrointestinal tract other than Billroth I. 5. Difficulty in discontinuing or substituting antithrombotic therapy according to the "Guideline, Management of antithrombotic agents for endoscopic procedures." 6. Considered inappropriate for participation in this study at the discretion of the investigator.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Proportion of event-free survivors at 12 weeks (recurrent biliary obstruction, pancreatitis, cholecystitis, non stent related cholangitis, gastrointestinal bleeding, aspiration pneumonia, liver abscess, gastrointestinal perforation, or death). | — |
Secondary
| Measure | Time frame |
|---|---|
