What researchers measure

Primary outcomes

  1. Freedom from symptomatic recurrent biliary obstruction requiring reintervention

    Time frame: 6 months

Secondary outcomes

  1. Technical success

    Technical success is defined as a stent successfully delivered and placed at its intended location at the end of the procedure.

    Time frame: Immediately following completion of the stent placement procedure

  2. Incidence of device-related adverse events

    Time frame: 6 months

  3. Ease of use

    Ease of use will be evaluated on a five point scale ranging from very easy to very difficult.

    Time frame: Immediately following completion of the stent placement procedure
