Preventing acute cholecystitis using endoscopic techniques

Efficacy of ETGBD Parallel Insertion With Fully Covered Self-expandable Metal Stent for Preventing Acute Cholecystitis in Patients With Low Cystic Duct Insertion

NA · Seoul National University Hospital · NCT06287112

This study is testing if a new endoscopic technique can help prevent acute cholecystitis in patients with certain conditions better than standard care.

What this trial studies

This clinical trial aims to evaluate the efficacy of endoscopic transpapillary gallbladder drainage (ETGBD) combined with the insertion of a fully covered self-expanding metal stent in preventing acute cholecystitis in patients with specific anatomical conditions. The study hypothesizes that this approach will reduce the frequency and severity of complications associated with biliary obstruction. Participants will be monitored for the occurrence of cholecystitis and the need for additional invasive procedures. The trial will compare outcomes in patients receiving this intervention against standard care.

Who should consider this trial

Good fit: Ideal candidates are adults aged 19 and older with confirmed biliary obstruction and specific anatomical conditions.

Not a fit: Patients with prior gallbladder drainage procedures or those with acute cholecystitis will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of acute cholecystitis in at-risk patients.

How similar studies have performed: While similar approaches have been explored, this specific combination of ETGBD and fully covered stents is novel and has not been extensively tested.
