Laser utility in the treatment of hemorrhoidal pathology: a review of literature

Hemorrhoidal disease is a common reason for consultation in proctology. It can be treated in several ways (medical, endoscopic, and surgical). Laser treatment has been described since 1960 and has developed in recent years. The purpose of this literature review was to study the results of laser treatment of hemorrhoids and to compare them with those of surgical methods. We performed a systematic search of the literature by querying the Medline, Google Scholar, and Cochrane Library databases. Retrospective studies and case reports were excluded. We selected 11 studies both techniques HeLP (hemorrhoid laser procedure) and LHP (laser hemorrhoidoplasty procedure). The total number of patients was 1179 including 1059 patients treated with laser and 120 treated surgically within the context of comparative studies. The age of the patients varies between 18 and 74 years old. HeLP laser treatment was significantly superior to surgical treatment in terms of postoperative pain (p < 0.001), hemorrhoidal disease downgrading (p < 0.001), and postoperative satisfaction (p < 0.001). Similarly, LHP laser treatment was significantly superior to surgical treatment in terms of operative duration (p < 0.00001), intraoperative bleeding (p < 0.00001), postoperative pain at H12 and H24 (p < 0.00001 and p = 0.0003), and postoperative bleeding rate (p < 0.001). The laser represents a revolution in the field of proctology mainly in the treatment of hemorrhoidal pathology. It is a safe, effective, and less painful mini-invasive technique. More rigorous studies will be needed to better evaluate this technique.
