Hemorrhoids is one of the most common proctological diseases of the anal canal. In the guidelines presented in 2018 in „Diseases of the Colon & Rectum”, the American Society of Colon and Rectal Surgeons (ASCRS) hasn’t specified laser techniques as a method of treatment. The first attempts of laser trail in hemorrhoidal treatment were made at the end of the 70s by using laser CO2 instead of scalpel. Nowadays one of the newest devices is Leonardo laser which emits fan-shaped movement of 1470 nm length. It enabled the development of laser hemorrhoidoplasty technique (LHP). The advantage of this procedure is decrease of hemorrhoidal plexus by obliteration of hemorrhoidal vessels leading to their fibrosis. It reclaims almost anatomical architecture of anal canal without a necessity to excise the extended hemorrhoids. Development of the connective tissue fibers guarantees adequate adhesion of mucosa to the underlying tissue which prevents the recurrence of the disease, especially the ones connected with prolapsing of hemorrhoids. The article contains a description of the method recommended by the manufacturer of Leonardo laser with the autors’ modifications developed on the basis of their own experience.
