Minimally invasive hemorrhoid surgery, because there is no surgical incision around the anus, patients recover faster and suffer less postoperative pain. minimally invasive hemorrhoid surgery includes RPH and PPH. the first, RPH, also known as automatic ligation, is generally indicated for stage I and II internal hemorrhoids whose main symptom is bleeding without severe protruding symptoms, and cannot be used to treat external hemorrhoids. After surgery, patients may experience anal swelling and discomfort due to the ligation of internal hemorrhoids, and the symptoms usually disappear in 5-7 days after surgery. The second, PPH, also known as suprahemorrhoidal mucosal circumferential excision and stapling, is generally indicated for more severe circumferential mixed hemorrhoids. During the surgery, the rectal mucosa is removed circumferentially and then stapled, which has a lifting effect and is more effective in treating external hemorrhoids. However, minimally invasive surgery for hemorrhoids requires the use of surgical instruments, which are self-funded, so the cost of treatment is relatively high.
