The recovery time for anal surgery depends on which kind of surgery was done on the anus. If the surgery was done for anal fissure or mixed hemorrhoids, the recovery time after surgery is about 4 weeks. If the surgery is for perianal abscess or fistula, the recovery time can be roughly estimated according to the size of the abscess cavity or the direction of the fistula, which is the size of the lesion. If the pus cavity is larger or the fistula is more complicated, the recovery time will be longer, and the recovery time for most perianal abscesses or fistulas is about 40-50 days; patients with severe degrees can basically recover completely in 2 months.
