Usually, it takes half a month to a month for the wound to recover after the anal canal removal surgery. However, due to the different physical conditions of each person, the severity of the disease and the maintenance after the surgery, the recovery time will be different. If the condition is not very serious, the trauma after surgery is not very large, and there are no complications after surgery, you can recover in about half a month. If the trauma is large, because the anus is empty after removal, the skin healing rate will grow slowly, and infection and inflammation will occur during the recovery period, the recovery time will be extended and take about a month. Once the surgery is over, you need to go to the hospital for regular medication changes, and you need to eat a light and nutritious diet and pay attention not to have infections.
