After surgery, scar tissue proliferation can easily occur, especially with repeated stimulation of defecation, which can also lead to aggravation of the disease. Physiotherapy can be used to gradually improve the condition. Applying warm salt water or potassium permanganate in a sitz bath every day before going to bed can soften the scar and help stop itching. After each bowel movement, you should wash promptly, which can also relieve the symptoms. It is also important to pay attention to the regularity of life, not to overeat, to develop good habits of regular bowel movements, and not to drink and smoke, and not to eat spicy food and stimulating food. For severe scar tissue hyperplasia, which can also affect the bowel function of the patient, surgical treatment is required if necessary, that is, removal of the scar tissue.
