Current Primary Outcome Measures  ICMJE
 (submitted: December 5, 2018)
Resolution of Acute Cholecystitis [ Time Frame: Up to 15 weeks ]
Time to resolution of acute cholecystitis measured in days. Resolution is defined as either a fever of less than 100.5°F, or at least a 4-point decrease in the pain score, or WBC count less than 12,000/cc, with improvement in at least two of these categories without the deterioration of the third category.

Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: December 5, 2018)
Rate of re-interventions [ Time Frame: Through study completion, Up to 15 weeks ]
Rate of re-interventions including but not limited to stent migration, stent occlusion by GB stones, and luminal debridement.
Original Secondary Outcome Measures  ICMJE Same as current
Current Other Pre-specified Outcome Measures
 (submitted: December 5, 2018)
  • Stent Patency [ Time Frame: Intraoperative (Stent placement through stent removal) ]
    Stent patency (ability to facilitate gallbladder drainage) defined indirectly as resolution of acute cholecystitis or, in the absence of resolution of acute cholecystitis, endoscopic observation of unobstructed AXIOSTM stent lumen
  • Technical stent placement success [ Time Frame: Intraoperative (stent placement) ]
    Technical AXIOS stent placement success, defined as transmural placement of the AXIOSTM stent with confirmed stent patency via (i) drainage visualized through the stent or fluoroscopically, or (ii) ability to endoscopically observe the inner walls of the gallbladder through the AXIOSTM stent
  • Technical stent removal success [ Time Frame: Intraoperative (stent removal) ]
    Technical stent removal success, defined as the ability to remove the AXIOS stent endoscopically without stent removal related serious adverse events
  • Acute Cholecystitis recurrence [ Time Frame: Through study completion, up to 15 weeks ]
    Recurrence of acute cholecystitis and its management post AXIOS stent removal
  • Number of cumulative hospital and ICU days [ Time Frame: Through study completion, up to 15 weeks ]
    Number of cumulative hospital and ICU days from initial stent placement to resolution of symptoms of acute cholecystitis
Original Other Pre-specified Outcome Measures Same as current
Descriptive Information
Brief Title  ICMJE AXIOS™ for Gallbladder Drainage as an Alternative to Percutaneous Drainage IDE
Official Title  ICMJE A Multicenter, Prospective Study of EUS-Guided Transluminal Gallbladder Drainage in Patients With Acute Cholecystitis as an Alternative to Percutaneous Gallbladder Drainage
Brief Summary To evaluate the safety and effectiveness of the AXIOS™ Stent with Electrocautery Enhanced Delivery System in the management of symptoms of acute cholecystitis as an alternative to percutaneous gallbladder drainage.
Detailed Description This study is a prospective, single arm, multi center trial. Treatment of up to 30 patients will take place at up to 9 clinical centers. Patients who meet all eligibility criteria will receive the AXIOS stent for up to 60 days indwell and 72 hour follow-up after stent removal.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  1. Patient requiring intervention for the management of symptoms associated with acute cholecystitis
