BACKGROUND: Postoperative abdominal adhesions (PAAs) represent a frequent condition occurring in more than 90% of patients undergoing abdomen and pelvic surgeries, which can cause chronic abdominal pain, female infertility, and repeated bowel obstruction, requiring repetitive surgical interventions causing morbidity and mortality, as well as high costs. It is therefore of paramount clinical importance and significance to develop practical and reliable strategies for preventing the occurrence of PAAs. METHODS AND RESULTS: In this study, we demonstrated that Nianfukang (NFK, composed of polyethylene glycol 1450 and diclofenac sodium) is highly effective in preventing PAAs, likely by reducing leukocytes and inflammatory factors in the abdominal cavity, and inhibiting intestinal fibrosis in a rat model of PAAs induced by postoperative cecum scraping. We further uncovered that NFK downregulates the expression of TGF-ß1, a key factor for adhesion formation, to suppress the TGF-ß1/TGF-ßRIII/Smad2 signaling pathway, thereby inhibiting the proliferation and migration of fibroblasts and provided evidences for the involvement of the TGF-ß1/TGF-ßRIII/Smad2 axis in the prevention of PAAs in normal human colon fibroblast CCD-18Co. CONCLUSIONS: Our findings support NFK as a potential anti-adhesive product that has the advantages of significant effectiveness, safety profile, and low cost, as well as clear mechanism of action.
