A zwitterionic dual-network hydrogel patch with anti-inflammatory properties for efficient peritoneal adhesion prevention.

Postoperative peritoneal adhesion, driven by inflammatory response and fibrotic deposition, remains the most common complication following abdominal surgeries, with limited effective solutions.
