Is hemorrhoids surgery a traditional operation or a minimally invasive operation?

The advantages of minimally invasive surgery are beyond doubt. Its advantages are: (1) no pain after operation; (2) Short operation time, little injury and quick recovery; (3) There is no injury to anal sphincter, incontinence and anal stenosis; (4) The recurrence rate of hemorrhoids is low and the appearance is beautiful. Traditional surgery cannot be compared with it. The traditional method is mainly low in price and easy to be accepted by the general public.
