Whether the recovery from a second surgery for anal fistula is quick primarily depends on whether the surgical wound is infected and bleeding, and it is also directly related to the patient's own immunity and the size of the wound.

Generally, if the wound from the second surgery is relatively small and the patient does not have diabetes, tuberculosis, or inflammatory bowel disease, then the postoperative recovery tends to be quicker. Moreover, the patient should eat foods rich in high-quality protein and persist in changing dressings to avoid infection and bleeding of the wound, which also facilitates recovery after anal fistula surgery.

However, if the wound from the anal fistula surgery is larger and the second procedure involves the seton technique, and since the patient's second surgery is for a high complex anal fistula, the recovery time is relatively slower. Additionally, if the patient has diabetes or inflammatory bowel disease, this will directly affect the postoperative recovery.
