What this trial studies

This clinical trial investigates the efficacy of prophylactic injection of a saline-epinephrine solution to prevent delayed bleeding following endoscopic sphincterotomy (EST). It is a single-blinded, parallel group, multi-center, randomized controlled trial involving approximately 400 participants, divided into two groups: one receiving the injection and the other not. The primary outcome measured will be the incidence of delayed post-EST bleeding within 30 days after the procedure. Secondary outcomes include the rate of adverse effects and the need for additional hemostatic interventions.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 20 years or older who experience transient bleeding after endoscopic sphincterotomy.

Not a fit: Patients with prior sphincterotomy, severe liver disease, or active gastrointestinal bleeding are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of delayed bleeding complications in patients undergoing endoscopic sphincterotomy.

How similar studies have performed: While the use of epinephrine for managing post-sphincterotomy bleeding is common, the specific prophylactic approach being tested in this trial is novel and has not been extensively studied.
