Study summary

The study will compare the outcomes of patients with gallstone related cholecystitis who are poor surgical candidates undergoing EUS guided cholecystoenterostomy via a lumen apposing metal stent (LAMS).

Read the detailed description

The study will include patients with stone related cholecystitis that are not adequate surgical candidates that will be treated with EUS guided cholecystoenterostomy with endoscopic stone extraction. Patients will be randomized to stent removal immediately after gallstones have been removed or to observation for 1 year with the stent in place. Outcomes to be measured include recurrence of stone disease and rate of complications from the procedure in both groups

Study arms

  • Experimental
    Scheduled removal

    This group involves patients who will have the LAMS removed immediately after all the stones have been cleared from the gallbladder

    Procedure: Stent removal

  • Active comparator
    Observation

    This group involves patients who will be followed closely for 1 year after all the stones have been removed from the gallbladder. These patients will keep the stent in place for 1 year and at that time the patients will be offered removal of the stent.

    Procedure: Stent removal

Interventions

  • ProcedureStent removal

    This is a procedural intervention in which the stent will be removed via endoscopy.

06

What researchers measure

Primary outcomes

  1. Recurrence of GB findings

    To compare the recurrence of GB findings in patients undergoing EUS guided GB drainage with a lumen-apposing metal stent(LAMS) assigned to scheduled stent removal vs those assigned to long-term observation only.

    Time frame: 1 year

Secondary outcomes

  1. Rate of adverse events related to LAMS

    To compare the rate of LAMS related adverse events in these two groups

    Time frame: 1 year
