Comparing EUS-guided gallbladder drainage to antibiotics for high-risk patients with acute cholecystitis
Official title: Upfront Endoscopic Ultrasound-guided Gallbladder Drainage (EUS-GBD) Versus Standard Protocol (Antibiotics First) for Mild to Moderate Acute Cholecystitis in Patients Who Are Very-high-risk for Cholecystectomy: A Randomized-controlled Trial.
Run by Chinese University of Hong Kong · NCT05893511 · Data updated 2026-11-12
This study is testing whether draining the gallbladder using a special ultrasound technique works better than antibiotics for high-risk patients with acute cholecystitis.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18 and older suffering from mild to moderate acute calculous cholecystitis who are at very high risk for surgery.
✕Probably not a fit
Patients with severe acute cholecystitis, those with certain comorbidities, or those unwilling to participate in follow-up assessments may not benefit from this study.

What this trial studies
This clinical trial aims to evaluate the effectiveness of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) compared to a standard antibiotic treatment in patients at very high risk for surgery due to mild to moderate acute cholecystitis. The study will randomly assign participants to receive either EUS-GBD or antibiotics first, with the primary goal of determining the rate of recurrent acute cholecystitis within one year. This international randomized controlled trial will include patients aged 18 and older who meet specific inclusion criteria related to their health status and the severity of their condition.
Why it matters
Potential benefit: If successful, this approach could provide a less invasive treatment option for high-risk patients, potentially reducing the recurrence of acute cholecystitis.
How similar studies have gone: While the approach of EUS-GBD is gaining attention, this specific comparison against antibiotics in high-risk patients is relatively novel and has not been extensively tested in prior studies.
