About this study
Official title: Supra-papillary Versus Trans-papillary Biliary Stenting in Malignant Peri-hilar Stenosis (SupraBilS): a Randomized Controlled Trial
This is a randomized controlled trial comparing patients with obstructive jaundice due to malignancies of the perihilar area of bile ducts and undergoing both preoperative and palliative biliary drainage. The comparison will focus on the technique:, on the one hand, an arm of patients undergoing standard-of-care ERCP with trans-papillary plastic protesis placement, and on the other hand, an experimental arm of patients undergoing suprapapillary plastic protesis placement with no sphincterotomy. The primary objective will be to compare the time-to-stent dysfunction in the two groups; secondary objectives will include a comparison of the safety, technical, and clinical success of the procedures.

What is being measured
The primary outcome is the main question the study is designed to answer.
Time-to-Stent disfunction
In days, calculated from the index procedure. Stent(s) dysfunction, which includes occlusion or migration of the stent(s) and tumour ingrowth/overgrowth, is defined as the presence of at least two of the following three criteria:
- New dilation of the biliary tree on imaging:
- Bilirubin level above 2 mg/dL (34.2 mmol/L) with a new increase ≥ 1 mg/dL compared with the value after initial clinical success, or elevation of alkaline phosphatase and/or g-glutamyl transferase greater than 2 times the upper normal limit with a new elevation of 30 U/L
- Cholangitis, characterized by fever along with leucocytosis (> 10,000/mL) or C-reactive protein levels above 20 mg/dL.
Measured: From index procedure to a minimum of one year of follow up.
Secondary outcomes (3)
Safety of the procedure
The incidence of Adverse events and severe adverse events will be compared. Adverse events (AEs) (timepoint 14 days) are defined according to the ASGE lexicon and graded according to the Adverse Events in GI endoscopy (AGREE) classification that classifies AEs in 5 grades from Grade I, any deviation from standard postprocedural course without need for pharmacological or interventional treatment, to Grade V, death of the patient. Sub-group analysis will be performed for procedure-related AEs. Severe adverse events are defined as AGREE≥3.
Measured: From the index procedure within 14 days.
Technical success
Defined as the placement of the stent(s) in the desired position (timepoint 0)
Measured: At the moment of index procedure.
Clinical Success
Defined as the reduction of bilirubin level ≥50% or at a level <2 mg/dL (34.2 mmol/L).
Measured: Between 14 and 30 days from the index procedure.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a randomized controlled trial comparing patients with obstructive jaundice due to malignancies of the perihilar area of bile ducts and undergoing both preoperative and palliative biliary drainage. The comparison will focus on the technique:, on the one hand, an arm of patients undergoing standard-of-care ERCP with trans-papillary plastic protesis placement, and on the other hand, an experimental arm of patients undergoing suprapapillary plastic protesis placement with no sphincterotomy. The primary objective will be to compare the time-to-stent dysfunction in the two groups; secondary objectives will include a comparison of the safety, technical, and clinical success of the procedures.
