In terms of the precision of the surgery and the degree of pain caused to the patient, it is obviously better compared to traditional surgery PPH surgery for the following reasons: 1. PPH surgery is more precise and causes less damage to the patient compared to traditional hemorrhoid surgery, especially to be able to remove the mucosa as well as the submucosal tissue from the hemorrhoid all at once. This treatment is similar to the usual rectal anatomy, minimizing the appearance of surgical sequelae.2. The most important point of hemorrhoid cutting surgery is to prevent anal stenosis from occurring. Traditional surgery requires cutting the anal sphincter first, which can easily lead to fecal incontinence, but PPH surgery does not need to do so, and PPH surgery is less risky and less traumatic for patients compared to traditional surgery.
