Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Total 211 patients underwent pancreatoduodenectomy after preoperative biliary drainage at Seoul National University Hospital.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
144 patients and 68 patients were intended to be treated with ERBD/ENBD and PTBD, respectively. Among 144 patients, 39 patients were switched to PTBD due to a procedure failure. Finally, 104 and 107 patients were treated with ERBD/ENBD and PTBD, respectively. Clinical outcomes were compared on the basis on the final drainage method

Reporting Groups
ERBD biliary drainage : biliary drainage via ERBD/ENBD
PTBD biliary drainage : biliary drainage via PTBD
