The so-called minimally invasive external hemorrhoids are excision methods with incisions <1cm, which are often used for patients with mild cases or small external hemorrhoids. For example, ring-shaped hemorrhoids and semi-ring-shaped hemorrhoids can be treated with minimally invasive treatment, which requires 3-5 incisions for treatment. Soybean or corn-like external hemorrhoids can be treated with minimally invasive techniques such as laser and freezing. It is usually cured basically completely in 1-2 weeks. After surgery, you need to maintain local hygiene, change the medication regularly every day, eat a light diet, avoid spicy and greasy, quit smoking and alcohol, and pay attention to keeping warm to prevent the condition from getting cold.
