AIM: to evaluate the results of submucosal laser destruction of hemorrhoids using a W-laser.PATIENTS AND METHODS: one-hundred twenty-four patients with chronic hemorrhoids underwent submucosal W-laser destruction of hemorrhoidal piles in September 2017 – January 2019.RESULTS: the time of the procedure was 18-22 minutes. The hospital stay was 7-10 hours. The maximal edema of the pararectal area appeared by the 3rd days and was resolved on 13-14 days. The size of the edema depended on the volume of anesthetic. Maximal pain was observed on days 1 and 3 after surgery. The period for taking analgesics was not more than 7 days. No prolapse of hemorrhoidal piles was detected in all patients after 4 weeks postoperatively. No rectal bleeding was detected in 97.3%. The excellent result of treatment was found in 70.2%, good – in 22.6%, bad – in 7.2%.CONCLUSION: submucosal W-laser destruction of hemorrhoidal piles showed a less pain intensity after surgery and a decrease in the complication rate, fast recovery and better quality of life.
