Abstract
BACKGROUND: We hypothesize that excessive fibrin formation and inflammation induced by antiadhesive material, SurgiWrap (SW), would have an adverse effect on wound healing. It was evaluated by a thyroidectomy murine wound model.
METHODS: Excessive fibrin formation was induced by isthmectomy without hemostasis. Rats were allocated into isthmectomy with SurgiWrap (I+SW+), I+SW-, I-SW+, I-SW-, and isthmectomy after electrocautery for hemostasis (I+C+SW-). The SWs were placed on the superficial and visceral layers for gross and microscopic evaluation.
RESULTS: Microscopic examination showed collagen deposition occurred in the I-SW- sham group and at a higher level in I+C+SW-. The collagen deposition decreased in groups without SW with time but increased in groups with SW. Use of SW produced more inflammation and more collagen deposition. The I+SW + group developed the largest area of collagen deposition at 4 weeks and more collagen deposition than the I-SW + group.
CONCLUSION: The SW induced more collagen deposition increasing with time. The collagen deposition produced by SW was worsened by excessive fibrin formation and inflammation.
