(A) The rat model of abdominal sidewall defect-cecum abrasion. (B) PECE hydrogel applied on the injured abdominal wall and cecum. (C) Score-4 adhesion was observed between the injured abdominal wall and cecum in an NS-treated rat; intestine segments and omentum adhesion to the sutured midline incisions were also observed. (D) No adhesion was observed in the PECE gel-treated group.

Abbreviations: NS, normal saline; PECE, poly (ethylene glycol)-poly (ɛ-caprolactone)-poly (ethylene glycol) (PEG-PCL-PEG).
