The actual fact is that you can find a lot of people who have been in the business for a long time. Shenyang Anorectal Hospital, Department of Anorectal Surgery, Liu Bin: In the north, severe mixed hemorrhoids are rarely selected for PPH surgery, which does not reflect the value of minimally invasive, our minimally invasive concept is less trauma, faster healing, good functional protection, and value for money. The actual fact is that you can find a lot of people who are not able to get a lot of information about the actual procedure. If there is still a lump outside the anus after the internal hemorrhoid is retracted, that is, if the external hemorrhoid is very obvious, it is not suitable for PPH surgery, but can be a combination of various methods, such as ligation, injection, and so on, which are all minimally invasive. The choice of which minimally invasive technique should be determined by the patient’s condition.
