The principle of PPH surgery is mainly to excise the mucosa of hemorrhoids, reduce local tissue proliferation, and lift up and fix the anal cushion. PPH surgery, i.e. anastomotic hemorrhoidal mucosal excision and stapling, is suitable for internal hemorrhoids of degree Ⅲ and Ⅶ, as well as internal hemorrhoids of degree Ⅱ and circumferential hemorrhoids that have failed non-surgical treatment. The main purpose of the procedure is to lift up and fix the displaced anal cushion, and the rectal mucosa and submucosa 2~4cm above 2cm from the dentate line are removed by tubular circular anastomosis. the procedure has the advantages of less pain, shorter operation time, and quicker recovery. When suffering from hemorrhoids, you should seek medical treatment in time, choose the appropriate treatment under the guidance of professional doctors, and adjust your lifestyle in order to maximize the quality of life.
