Could conscious sedation replace general anesthesia for gallbladder drainage?

NCT ID NCT07704021

First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time

Summary

This study tests whether endoscopic ultrasound-guided gallbladder drainage can be safely performed using conscious sedation given by the endoscopist, instead of deep sedation or general anesthesia. The trial enrolls elderly, high-risk patients with acute cholecystitis who are not candidates for surgery. Researchers will monitor for sedation-related complications such as low oxygen levels or need for airway support, as well as procedure-related problems within 30 days.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
endoscopic ultrasound-guided gallbladder drainage under endoscopist-directed conscious sedation
What this could lead to
If successful, this approach could offer a safer, less invasive drainage option for elderly or frail patients who cannot undergo surgery or tolerate general anesthesia.
What could go wrong
This is a small, single-center study with only 48 participants, so results may not apply broadly. Conscious sedation may still carry risks like oxygen drops or need for emergency deeper sedation.
