10-20 days after anal fistula surgery, the wound more fresh granulation tissue growth, bright red, belongs to the normal performance of wound healing.
The recovery process after anal fistula surgery mainly includes inflammatory phase, granulation growth phase, epithelial covering phase. Among them, 10-20 days after anal fistula surgery with the fading of necrotic tissue, there will be fresh granulation tissue growth.
Normal flat granulation is a sign of wound healing and growth of meat, but excessive friction on the wound surface will easily lead to abnormal proliferation of granulation tissue, which is higher than the skin, or the granulation tissue is uneven, it is generally recommended to trim, trimming and flattening is more conducive to wound healing, epithelial tissue coverage, so as not to lead to pseudo-healing of the wound.
