AXIOS™ Stent over swirling line background.

Alternative effective care for high-risk cholecystitis patients

Patients deserve effective care options that may reduce pain and reinterventions while preserving quality of life.*1 Managing acute cholecystitis to give patients a drain-free life may be achieved through minimally invasive treatment alternatives including internal EUS-guided drainage or IR-guided gallstone removal. Boston Scientific offers a portfolio to assist in these treatments. We offer AXIOS™ Stent and Delivery System for internal drainage and SpyGlass™ Discover Digital Catheter for IR-guided gallstone removal.

When surgery is not an option, learn how EUS-guided gallbladder drainage with the AXIOS Stent may work as a viable treatment alternative.

Clinical benefits of AXIOS Stent technology

EUS-guided GBD with the AXIOS Stent and Electrocautery Enhanced Delivery System may keep patients free of an external drain from the onset, reducing the need for repeat drain procedures – and the risk of infection.†,2,3

Clinical background

In most cases, early laparoscopic cholecystectomy is the treatment of choice for acute cholecystitis. Yet it’s considered a high-risk procedure for the elderly, critically ill, those with significant comorbidities, and other nonsurgical candidates, making GBD a recommended treatment alternative.4

Percutaneous transhepatic gallbladder drainage (PT-GBD) has been the most common GBD technique used in clinical practice, but now there’s another option. EUS-guided GBD gives surgeons, interventional radiologists, and therapeutic endoscopists a treatment pathway that has benefits for patients, clinical teams, and hospitals.

Clinical outcomes and patient experience

With an expanded indication in the U.S., EUS-guided GBD using AXIOS Stent technology offers another viable treatment for managing acute cholecystitis for patients deemed as nonsurgical candidates.

EUS-guided GBD provides several clinical outcome benefits compared to PT-GBD, including reduced:

  • Short- and long-term adverse event rates*1
  • Reoccurrence rates*1
  • Reinterventions*1
  • Post-procedural pain*1

EUS-guided GBD also reduces negative quality-of-life impacts associated with external drains, including:

  • Pain at drain site†2
  • Inconvenience of maintenance†2
  • Risk of infection at drain site†3
  • Risk of inadvertent dislodgement*†2

A groundbreaking endoscopic option for acute cholecystitis management

EUS-guided GBD adoption can reduce unplanned:

  • Hospital readmissions‡1
  • Procedures related to external drain exchanges1
  • Risk of infection at drain site†3
  • Risk of inadvertent dislodgement2

Clinical trial results: EUS-guided GBD versus PT-GBD

First prospective, multicenter, randomized controlled trial provides outcomes of EUS-guided GBD (n=39)  versus PT-GBD (n=40). This study has shown that technical success, clinical success, and 30-day mortality rates are similar. However, patients undergoing EUS-guided GBD had significantly lower rates of 30-day and 1-year adverse events (AEs), recurrence, reintervention, unplanned admission, and post-procedural pain.1

Outcome

Study Reported Results

(95% Confidence Interval)

Technical Success

97.4% (86.5%, 99.9%)

Clinical Success

92.3% (79.1%, 98.4%)

Recurrent Cholecystitis

Overall AEs

25.6% (13.0%, 42.1%)

Re-interventions

2.6% (0.1%, 13.5%)

Retrospective, multicenter, comparative trial of 90 high-risk surgical patients with acute cholecystitis who underwent GBD. This study has shown that EUS-guided GBD has similar rates of technical and clinical success as PT-GBD, but reports shorter hospital stays, decreased need for reintervention, and a trend toward  fewer adverse events.2

Hot AXIOS 10mm×10mm and 15mm×10mm stents: The AXIOS Electrocautery-Enhanced-Stent and Delivery System is indicated for use to facilitate transgastric or transduodenal endoscopic drainage of symptomatic pancreatic pseudocysts ≥ 6 cm in size and walled-off necrosis ≥ 6 cm in size that are adherent to the gastric or bowel wall. Once placed, the AXIOS Stent functions as an access port allowing passage of standard and therapeutic endoscopes to facilitate debridement, irrigation, and cystoscopy. The stent is intended for implantation up to 60 days and should be removed upon confirmation of pseudocyst or walled-off necrosis resolution. The AXIOS Stent and Electrocautery-Enhanced Delivery System is indicated for use to facilitate transgastric or transduodenal endoscopic drainage of the gallbladder in patients with acute cholecystitis who are at high risk for surgery.
