A thermoresponsive positively charged PNIPAM/Ga3+ (PGa III) hydrogel sealant forms single-step Janus-type tissue adhesion and repairs gastrointestinal fistulas in rat and pig models.
- Why it matters: Gastrointestinal fistulas cause major morbidity and mortality, and endoscopic repair still struggles with combining easy delivery with hydrogel sealing that resists harsh conditions.
- What they did: The team created a slug-inspired biomimetic self-assembled, injectable PGa III hydrogel and tested it for endoscopic GF repair in living Sprague-Dawley rats and Bama miniature pigs.
- The result: PGa III effectively repaired gastrointestinal fistulas and supported non-invasive endoscopic surgery in both animal models, suggesting a route to safer, more effective clinical options and potential use in other organs.
