Self-assembling peptide (SAP) gel is a safe and effective endoscopic treatment for gastrointestinal bleeding (GIB), achieving 93.1% hemostasis. This innovative therapy shows promise for managing GIB with minimal adverse events.
Area of Science:
- Gastroenterology
- Biomaterials Science
Background:
- Gastrointestinal bleeding (GIB) is a significant cause of mortality, necessitating effective endoscopic treatments.
- Traditional endoscopic therapies include mechanical, thermal, and injection methods.
- Self-assembling peptide (SAP) gel presents a novel hemostatic agent for GIB management.
Approach:
- A systematic review and meta-analysis was conducted, searching major databases up to November 2022.
- Included 7 studies with 427 patients, analyzing hemostasis success, rebleeding, and adverse events.
- Employed random-effects models to calculate pooled estimates and 95% confidence intervals.
Key Points:
- SAP application was technically successful in all patients, including 34% on anticoagulation/antiplatelet agents.
- Pooled successful hemostasis rate was 93.1% (95% CI 84.7-97.0).
- Rebleeding rates were 8.9% (95% CI 5.3-14.4), with no SAP-related adverse events observed.
Conclusions:
- Self-assembling peptide (SAP) demonstrates safety and efficacy as an endoscopic treatment for GIB.
- SAP offers improved visualization compared to spray-based modalities.
- Further prospective or randomized controlled trials are warranted to validate these findings.
