After hemorrhoid surgery, there will be a certain amount of local trauma in the anus, and the wound will spread into the anal canal. If the wound is not changed properly or there is excessive local granulation, pseudo-healing will form. The clinical symptom of pseudo-healing is that the wound has grown and lived on the outside, and there will be local foci of inflammatory infection inside the wound, which will cause intermittent episodes of pain in the local anal wound. After the wound has pseudo-healed, the pseudo-healed wound needs to be opened as soon as possible to allow the hemorrhoid wound to grow from the inside out, and the wound needs to be properly disinfected, changed and drained. Only when the wound is drained and thoroughly disinfected can sterile growth be ensured. If there is excessive elevation of the granulation locally in the anus or on the outside of the wound, the excessive granulation needs to be trimmed at the time of dressing change to avoid pseudo-healing.
