How long it takes to recover from anal fissure surgery depends on the severity of the fissure and how the surgery was performed. In general, it takes about 2-4 weeks to recover from anal fissure surgery. Anal fissure is a rupture and tear of the skin of the anal canal, and the most common surgical treatment is anal fissure excision. If the extent of the patient’s fissure is not particularly serious and the scope is small, the post-operative wound usually starts to repair in about 1 week and can basically heal in about 4 weeks. If the degree of anal fissure is less severe, anal fissure suture surgery can also be taken, and in general, recovery can be made in about 2 weeks. It is important to note that most anal fissure surgical incisions are open incisions and each bowel movement by the patient will cause irritation to the incision and therefore may result in delayed healing of the incision. Patients with anal fissures should pay attention to a light diet after surgery, avoid spicy and stimulating foods, and increase the intake of vegetables, fruits and other coarse fiber foods. Develop good bowel habits, keep the bowels open, and clean and disinfect the incision in time after the bowel movement.
